The following solution is:

• briefest. Somewhat similar to here. It's also minimal: The table in the DIV is orthogonal to your question.
• fastest: getElementById is called once at the outset. This may or may not suit your purposes.
• It uses pure JavaScript (i.e. without JQuery).
• It uses a button. Your taste may vary.
• extensible: it's ready to add more DIVs, sharing the code.

mydiv = document.getElementById("showmehideme");_x000D_
_x000D_
function showhide(d) {_x000D_
    d.style.display = (d.style.display !== "none") ? "none" : "block";_x000D_
}

#mydiv { background-color: #ddd; }

<button id="button" onclick="showhide(mydiv)">Show/Hide</button>_x000D_
<div id="showmehideme">_x000D_
    This div will show and hide on button click._x000D_
</div>

Use show/hide method as below

$("div").show();//To Show

$("div").hide();//To Hide

Just wanted to illustrate, in the context of nested lists, the usefulness of the hidden checkbox <input> approach @jeffmcneill recommends — a context where each shown/hidden element should hold its state independently of focus and the show/hide state of other elements on the page.

Giving values with a common set of beginning characters to the id attributes of all the checkboxes used for the shown/hidden elements on the page lets you use an economical [id^=""] selector scheme for the stylesheet rules that toggle your clickable element’s appearance and the related shown/hidden element’s display state back and forth. Here, my ids are ‘expanded-1,’ ‘expanded-2,’ ‘expanded-3.’

Note that I’ve also used @Diepen’s :after selector idea in order to keep the <label> element free of content in the html.

Note also that the <input> <label> <div class="collapsible"> sequence matters, and the corresponding CSS with + selector instead of ~.

Use following JQuery. Demo

$(function() {
    $('#row_dim').hide(); 
    $('#type').change(function(){
        if($('#type').val() == 'parcel') {
            $('#row_dim').show(); 
        } else {
            $('#row_dim').hide(); 
        } 
    });
});

I would like to do this without attaching a class to every td

Personally, I would go with the the class-on-each-td/th/col approach. Then you can switch columns on and off using a single write to className on the container, assuming style rules like:

table.hide1 .col1 { display: none; }
table.hide2 .col2 { display: none; }
...

This is going to be faster than any JS loop approach; for really long tables it can make a significant difference to responsiveness.

If you can get away with not supporting IE6, you could use adjacency selectors to avoid having to add the class attributes to tds. Or alternatively, if your concern is making the markup cleaner, you could add them from JavaScript automatically in an initialisation step.

You can use .is(':visible') to test if something is visible and .is(':hidden') to test for the opposite:

$('#offers').toggle(!$('#column-left form').is(':visible')); // or:
$('#offers').toggle($('#column-left form').is(':hidden'));

Why don't you try the fadeIn() instead of using a show() with delay(). I think what you are trying to do can be done with this. Here is the jQuery code for fadeIn and FadeOut() which also has inbuilt method for delaying the process.

$(document).ready(function(){
   $('element').click(function(){
      //effects take place in 3000ms
      $('element_to_hide').fadeOut(3000);
      $('element_to_show').fadeIn(3000);
   });
}

UPDATE 2

@Override
    protected void onResume() {
        super.onResume();
        mUserNameEdit.requestFocus();

        mUserNameEdit.postDelayed(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                InputMethodManager keyboard = (InputMethodManager)
                getSystemService(Context.INPUT_METHOD_SERVICE);
                keyboard.showSoftInput(mUserNameEdit, 0);
            }
        },200); //use 300 to make it run when coming back from lock screen
    }

I tried very hard and found out a solution ... whenever a new activity starts then keyboard cant open but we can use Runnable in onResume and it is working fine so please try this code and check...

UPDATE 1

add this line in your AppLogin.java

mUserNameEdit.requestFocus();

and this line in your AppList.java

listview.requestFocus()'

after this check your application if it is not working then add this line in your AndroidManifest.xml file

<activity android:name=".AppLogin" android:configChanges="keyboardHidden|orientation"></activity>
<activity android:name=".AppList" android:configChanges="keyboard|orientation"></activity>

ORIGINAL ANSWER

 InputMethodManager imm = (InputMethodManager)this.getSystemService(Service.INPUT_METHOD_SERVICE);

for hide keyboard

 imm.hideSoftInputFromWindow(ed.getWindowToken(), 0); 

for show keyboard

 imm.showSoftInput(ed, 0);

for focus on EditText

 ed.requestFocus();

where ed is EditText

To get all column name you can iterate over the data_all2.columns.

columns = data_all2.columns
for col in columns:
    print col

You will get all column names. Or you can store all column names to another list variable and then print list.

Use media queries. Your CSS code would be:

@media screen and (max-width: 1024px) {
    .yourClass {
        display: none !important;
    }
}

The problem you're having is that the event-handlers are being bound before the elements are present in the DOM, if you wrap the jQuery inside of a $(document).ready() then it should work perfectly well:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").show("slow");
        });

    });

An alternative is to place the <script></script> at the foot of the page, so it's encountered after the DOM has been loaded and ready.

To make the div hide again, once the #music element is clicked, simply use toggle():

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").toggle();
        });
    });

JS Fiddle demo.

And for fading:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").fadeToggle();
        });
    });

JS Fiddle demo.

Try something like this

jQuery

$('#toggle_icon').toggle(function() {

    $('#toggle_icon').text('-');
    $('#toggle_text').slideToggle();

}, function() {

    $('#toggle_icon').text('+');
    $('#toggle_text').slideToggle();

});

HTML

<a href="#" id="toggle_icon">+</a>

<div id="toggle_text" style="display: none">
    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s
</div>

You can use the below effect to animate, you can change the values as per your requirements

$("#myElem").fadeIn('slow').animate({opacity: 1.0}, 1500).effect("pulsate", { times: 2 }, 800).fadeOut('slow'); 

It is possible to show smooth if you use Animation. In style just add "animation: show 1s" and the whole appearance discribe in keyframes.

Before you use DecimalFormat you need to use the following import or your code will not work:

import java.text.DecimalFormat;

The code for formatting is:

DecimalFormat precision = new DecimalFormat("0.00"); 
// dblVariable is a number variable and not a String in this case
txtTextField.setText(precision.format(dblVariable));

Bless is a high quality, full featured hex editor.

It is written in mono/Gtk# and its primary platform is GNU/Linux. However it should be able to run without problems on every platform that mono and Gtk# run.

Bless currently provides the following features:

• Efficient editing of large data files and block devices.
• Multilevel undo - redo operations.
• Customizable data views.
• Fast data rendering on screen.
• Multiple tabs.
• Fast find and replace operations.
• A data conversion table.
• Advanced copy/paste capabilities.
• Highlighting of selection pattern matches in the file.
• Plugin based architecture.
• Export of data to text and html (others with plugins).
• Bitwise operations on data.
• A comprehensive user manual.

wxHexEditor is another Free Hex Editor, built because there is no good hex editor for Linux system, specially for big files.

• It uses 64 bit file descriptors (supports files or devices up to 2^64 bytes , means some exabytes but tested only 1 PetaByte file (yet). ).
• It does NOT copy whole file to your RAM. That make it FAST and can open files (which sizes are Multi Giga < Tera < Peta < Exabytes)
• Could open your devices on Linux, Windows or MacOSX.
• Memory Usage : Currently ~10 MegaBytes while opened multiple > ~8GB files.
• Could operate thru XOR encryption.
• Written with C++/wxWidgets GUI libs and can be used with other OSes such as Mac OS, Windows as native application.
• You can copy/edit your Disks, HDD Sectors with it.( Usefull for rescue files/partitions by hand. )
• You can delete/insert bytes to file, more than once, without creating temp file.

DHEX is a more than just another hex editor: It includes a diff mode, which can be used to easily and conveniently compare two binary files. Since it is based on ncurses and is themeable, it can run on any number of systems and scenarios. With its utilization of search logs, it is possible to track changes in different iterations of files easily. Wikipedia article

You can sort on Linux to find some more here: http://en.wikipedia.org/wiki/Comparison_of_hex_editors

You may want to use a nullable datetime. Datetime? someDate = null;

You may find instances of people using DateTime.Max or DateTime.Min in such instances, but I highly doubt you want to do that. It leads to bugs with edge cases, code that's harder to read, etc.

Ubuntu 14.04:

simple cat -e <filename> works just fine.

This displays Unix line endings (\n or LF) as $ and Windows line endings (\r\n or CRLF) as ^M$.

The answer by Peter Ritchie was what I wanted, and Stephen Cleary's article about returning early in ASP.NET was very helpful.

As a more general problem however (not specific to an ASP.NET context) the following Console application demonstrates the usage and behavior of Peter's answer using Task.ContinueWith(...)

static void Main(string[] args)
{
  try
  {
    // output "hello world" as method returns early
    Console.WriteLine(GetStringData());
  }
  catch
  {
    // Exception is NOT caught here
  }
  Console.ReadLine();
}

public static string GetStringData()
{
  MyAsyncMethod().ContinueWith(OnMyAsyncMethodFailed, TaskContinuationOptions.OnlyOnFaulted);
  return "hello world";
}

public static async Task MyAsyncMethod()
{
  await Task.Run(() => { throw new Exception("thrown on background thread"); });
}

public static void OnMyAsyncMethodFailed(Task task)
{
  Exception ex = task.Exception;
  // Deal with exceptions here however you want
}

GetStringData() returns early without awaiting MyAsyncMethod() and exceptions thrown in MyAsyncMethod() are dealt with in OnMyAsyncMethodFailed(Task task) and not in the try/catch around GetStringData()

Key thing is to add the recipients as a list of email ids in your sendmail call.

import smtplib
from email.mime.multipart import MIMEMultipart

me = "[email protected]"
to = "[email protected]"
cc = "[email protected],[email protected]"
bcc = "[email protected],[email protected]"

rcpt = cc.split(",") + bcc.split(",") + [to]
msg = MIMEMultipart('alternative')
msg['Subject'] = "my subject"
msg['To'] = to
msg['Cc'] = cc
msg.attach(my_msg_body)
server = smtplib.SMTP("localhost") # or your smtp server
server.sendmail(me, rcpt, msg.as_string())
server.quit()

Use brackets:

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND 
    (date='$Date_Today' 
     OR date='$Date_Yesterday' 
     OR date='$Date_TwoDaysAgo' 
     OR date='$Date_ThreeDaysAgo' 
     OR date='$Date_FourDaysAgo' 
     OR date='$Date_FiveDaysAgo' 
     OR date='$Date_SixDaysAgo' 
     OR date='$Date_SevenDaysAgo'
    )
");

But you should alsos have a look at the IN operator. So you can say ´date IN ('$date1','$date2',...)`

But if you have always a set of consecutive days why don't you do the following for the date part

date <= $Date_Today AND date >= $Date_SevenDaysAgo

In Eclipse, go to Build Path, click "Add Library", select JRE System Library, click "Next", select option "Workspace default JRE(i)", and click "Finish".

This worked for me.

Here is an easier way that worked for me:

const express = require('express');
var app = express();
var fs = require('fs');

app.post('/upload', async function(req, res) {

  var file = JSON.parse(JSON.stringify(req.files))

  var file_name = file.file.name

  //if you want just the buffer format you can use it
  var buffer = new Buffer.from(file.file.data.data)

  //uncomment await if you want to do stuff after the file is created

  /*await*/
  fs.writeFile(file_name, buffer, async(err) => {

    console.log("Successfully Written to File.");


    // do what you want with the file it is in (__dirname + "/" + file_name)

    console.log("end  :  " + new Date())

    console.log(result_stt + "")

    fs.unlink(__dirname + "/" + file_name, () => {})
    res.send(result_stt)
  });


});

For that you need to enter one command that is missing from bitbucket commands

Please try git init.

The ECMAscript standard does not specify which sort algorithm is to be used. Indeed, different browsers feature different sort algorithms. For example, Mozilla/Firefox's sort() is not stable (in the sorting sense of the word) when sorting a map. IE's sort() is stable.

You can use something like code below, if you need to affect only specific value, and not touch others:

view.getLayoutParams().width = newWidth;

If you are using Oracle Database then you can achieve this using contains query. Contains querys are faster than like query.

If you need all of the words

SELECT * FROM MyTable WHERE CONTAINS(Column1,'word1 and word2 and word3', 1) > 0

If you need any of the words

SELECT * FROM MyTable WHERE CONTAINS(Column1,'word1 or word2 or word3', 1) > 0

Contains need index of type CONTEXT on your column.

CREATE INDEX SEARCH_IDX ON MyTable(Column) INDEXTYPE IS CTXSYS.CONTEXT

An application binary interface (ABI) is similar to an API, but the function is not accessible to the caller at source code level. Only a binary representation is accessible/available.

ABIs may be defined at the processor-architecture level or at the OS level. The ABIs are standards to be followed by the code-generator phase of the compiler. The standard is fixed either by the OS or by the processor.

Functionality: Define the mechanism/standard to make function calls independent of the implementation language or a specific compiler/linker/toolchain. Provide the mechanism which allows JNI, or a Python-C interface, etc.

Existing entities: Functions in machine code form.

Consumer: Another function (including one in another language, compiled by another compiler, or linked by another linker).

In Android Studio, above Version 3.6, There is a new location to toggle Gradle's offline mode To enable or disable Gradle's offline mode.

To enable or disable Gradle's offline mode, select View > Tool Windows > Gradle from the menu. In the top bar of the Gradle window, click Toggle Offline Mode (near settings icon).

It's a little bit confusing on the icon, anyway offline mode is enabled when the toggle button is highlighted. :)

I would try one of the following:

1.> numpy.random.randint

import numpy as np
X1 = np.random.randint(low=0, high=10, size=(15,))

print (X1)
>>> array([3, 0, 9, 0, 5, 7, 6, 9, 6, 7, 9, 6, 6, 9, 8])

2.> numpy.random.uniform

import numpy as np
X2 = np.random.uniform(low=0, high=10, size=(15,)).astype(int)

print (X2)
>>> array([8, 3, 6, 9, 1, 0, 3, 6, 3, 3, 1, 2, 4, 0, 4])

3.> numpy.random.choice

import numpy as np
X3 = np.random.choice(a=10, size=15 )

print (X3)
>>> array([1, 4, 0, 2, 5, 2, 7, 5, 0, 0, 8, 4, 4, 0, 9])

4.> random.randrange

from random import randrange
X4 = [randrange(10) for i in range(15)]

print (X4)
>>> [2, 1, 4, 1, 2, 8, 8, 6, 4, 1, 0, 5, 8, 3, 5]

5.> random.randint

from random import randint
X5 = [randint(0, 9) for i in range(0, 15)]

print (X5)
>>> [6, 2, 6, 9, 5, 3, 2, 3, 3, 4, 4, 7, 4, 9, 6]

Speed:

? np.random.uniform and np.random.randint are much faster (~10 times faster) than np.random.choice, random.randrange, random.randint .

%timeit np.random.randint(low=0, high=10, size=(15,))
>> 1.64 µs ± 7.83 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

%timeit np.random.uniform(low=0, high=10, size=(15,)).astype(int)
>> 2.15 µs ± 38.6 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

%timeit np.random.choice(a=10, size=15 )
>> 21 µs ± 629 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)

%timeit [randrange(10) for i in range(15)]
>> 12.9 µs ± 60.4 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

%timeit [randint(0, 9) for i in range(0, 15)]
>> 20 µs ± 386 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

Notes:

1.> np.random.randint generates random integers over the half-open interval [low, high).

2.> np.random.uniform generates uniformly distributed numbers over the half-open interval [low, high).

3.> np.random.choice generates a random sample over the half-open interval [low, high) as if the argument a was np.arange(n).

4.> random.randrange(stop) generates a random number from range(start, stop, step).

5.> random.randint(a, b) returns a random integer N such that a <= N <= b.

6.> astype(int) casts the numpy array to int data type.

7.> I have chosen size = (15,). This will give you a numpy array of length = 15.

I'm not sure what you mean by having tried it onblur, but to get the length of any string, use its .length property, so in the case of a textbox or textarea:

document.getElementById("textarea").value.length

Changing that ID, of course, to whatever the actual ID is.

This is a javascript function adapted from @Telanor's code. When passing a image base64 as first argument to the function, it returns the base64 of the resized image. maxWidth and maxHeight are optional.

function thumbnail(base64, maxWidth, maxHeight) {

  // Max size for thumbnail
  if(typeof(maxWidth) === 'undefined') var maxWidth = 500;
  if(typeof(maxHeight) === 'undefined') var maxHeight = 500;

  // Create and initialize two canvas
  var canvas = document.createElement("canvas");
  var ctx = canvas.getContext("2d");
  var canvasCopy = document.createElement("canvas");
  var copyContext = canvasCopy.getContext("2d");

  // Create original image
  var img = new Image();
  img.src = base64;

  // Determine new ratio based on max size
  var ratio = 1;
  if(img.width > maxWidth)
    ratio = maxWidth / img.width;
  else if(img.height > maxHeight)
    ratio = maxHeight / img.height;

  // Draw original image in second canvas
  canvasCopy.width = img.width;
  canvasCopy.height = img.height;
  copyContext.drawImage(img, 0, 0);

  // Copy and resize second canvas to first canvas
  canvas.width = img.width * ratio;
  canvas.height = img.height * ratio;
  ctx.drawImage(canvasCopy, 0, 0, canvasCopy.width, canvasCopy.height, 0, 0, canvas.width, canvas.height);

  return canvas.toDataURL();

}

You have forgotten to mark the getProducts return type as an array. In your getProducts it says that it will return a single product. So change it to this:

public getProducts(): Observable<Product[]> {
    return this.http.get<Product[]>(`api/products/v1/`);
  }

None of the other answers suggests downloading just the missing plugin.

Before you delete your whole .m2 repository and re-download all project dependencies and all plugins, you may want to try:

mvn dependency:resolve-plugins

That will download just the missing plugins.

Here is a short cheatsheet that covers typical cases:

// sort
list.sort(naturalOrder())

// sort (reversed)
list.sort(reverseOrder())

// sort by field
list.sort(comparing(Type::getField))

// sort by field (reversed)
list.sort(comparing(Type::getField).reversed())

// sort by int field
list.sort(comparingInt(Type::getIntField))

// sort by double field (reversed)
list.sort(comparingDouble(Type::getDoubleField).reversed())

// sort by nullable field (nulls last)
list.sort(comparing(Type::getNullableField, nullsLast(naturalOrder())))

// two-level sort
list.sort(comparing(Type::getField1).thenComparing(Type::getField2))

When you do new Promise((resolve)... the type inferred was Promise<{}> because you should have used new Promise<number>((resolve).

It is interesting that this issue was only highlighted when the async keyword was added. I would recommend reporting this issue to the TS team on GitHub.

There are many ways you can get around this issue. All the following functions have the same behavior:

const whatever1 = () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever2 = async () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever3 = async () => {
    return await new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever4 = async () => {
    return Promise.resolve(4);
};

const whatever5 = async () => {
    return await Promise.resolve(4);
};

const whatever6 = async () => Promise.resolve(4);

const whatever7 = async () => await Promise.resolve(4);

In your IDE you will be able to see that the inferred type for all these functions is () => Promise<number>.

You can use the BS Typeahead fork which supports ajax calls. Then you will be able to write:

$('.typeahead').typeahead({
    source: function (typeahead, query) {
        return $.get('/typeahead', { query: query }, function (data) {
            return typeahead.process(data);
        });
    }
});

Recently travis killed the execution of a test (without having changed anything related (and successful builds on developer machines!)), thus BUILD FAILURE. One of the causes was this (see @agudian answer):

Surefire does not support tests or any referenced libraries calling System.exit()`

(since the test class indeed called System.exit(-1)).

1. Using a simple return statement instead helps.

2. To make travis happy again, I also had to add the surefire parameters (<argLine>) provided by @xiaohuo. (also, I had to remove -XX:MaxPermSize=256m to be able to build on one of my desktops)

Doing only one of the two things didn't worked.

For more background read When should we call System.exit in Java.

As @JaredPar pointed out in his answer use parseFloat with replace

var fullcost = parseFloat($("#fullcost").text().replace(',', '.'));

Just replacing the comma with a dot will fix, Unless it's a number over the thousands like 1.000.000,00 this way will give you the wrong digit. So you need to replace the comma remove the dots.

// Remove all dot's. Replace the comma.
var fullcost = parseFloat($("#fullcost").text().replace(/\./g,'').replace(',', '.'));

By using two replaces you'll be able to deal with the data without receiving wrong digits in the output.

Additionally, you could use just the same variable for the member of the input list which is currently accessed and for the element inside this member. However, this might even make it more (list) incomprehensible.

input = [[1, 2], [3, 4]]
[x for x in input for x in x]

First for x in input is evaluated, leading to one member list of the input, then, Python walks through the second part for x in x during which the x-value is overwritten by the current element it is accessing, then the first x defines what we want to return.

For anyone who comes across this in the future, I want to share this gem from the PHP docs, posted by an anonymous user:

There seems to be some confusion here. The distinction between pointers and references is not particularly helpful. The behavior in some of the "comprehensive" examples already posted can be explained in simpler unifying terms. Hayley's code, for example, is doing EXACTLY what you should expect it should. (Using >= 5.3)

First principle: A pointer stores a memory address to access an object. Any time an object is assigned, a pointer is generated. (I haven't delved TOO deeply into the Zend engine yet, but as far as I can see, this applies)

2nd principle, and source of the most confusion: Passing a variable to a function is done by default as a value pass, ie, you are working with a copy. "But objects are passed by reference!" A common misconception both here and in the Java world. I never said a copy OF WHAT. The default passing is done by value. Always. WHAT is being copied and passed, however, is the pointer. When using the "->", you will of course be accessing the same internals as the original variable in the caller function. Just using "=" will only play with copies.

3rd principle: "&" automatically and permanently sets another variable name/pointer to the same memory address as something else until you decouple them. It is correct to use the term "alias" here. Think of it as joining two pointers at the hip until forcibly separated with "unset()". This functionality exists both in the same scope and when an argument is passed to a function. Often the passed argument is called a "reference," due to certain distinctions between "passing by value" and "passing by reference" that were clearer in C and C++.

Just remember: pointers to objects, not objects themselves, are passed to functions. These pointers are COPIES of the original unless you use "&" in your parameter list to actually pass the originals. Only when you dig into the internals of an object will the originals change.

And here's the example they provide:

<?php

//The two are meant to be the same
$a = "Clark Kent"; //a==Clark Kent
$b = &$a; //The two will now share the same fate.

$b="Superman"; // $a=="Superman" too.
echo $a;
echo $a="Clark Kent"; // $b=="Clark Kent" too.
unset($b); // $b divorced from $a
$b="Bizarro";
echo $a; // $a=="Clark Kent" still, since $b is a free agent pointer now.

//The two are NOT meant to be the same.
$c="King";
$d="Pretender to the Throne";
echo $c."\n"; // $c=="King"
echo $d."\n"; // $d=="Pretender to the Throne"
swapByValue($c, $d);
echo $c."\n"; // $c=="King"
echo $d."\n"; // $d=="Pretender to the Throne"
swapByRef($c, $d);
echo $c."\n"; // $c=="Pretender to the Throne"
echo $d."\n"; // $d=="King"

function swapByValue($x, $y){
$temp=$x;
$x=$y;
$y=$temp;
//All this beautiful work will disappear
//because it was done on COPIES of pointers.
//The originals pointers still point as they did.
}

function swapByRef(&$x, &$y){
$temp=$x;
$x=$y;
$y=$temp;
//Note the parameter list: now we switched 'em REAL good.
}

?>

I wrote an extensive, detailed blog post on this subject for JavaScript, but I believe it applies equally well to PHP, C++, and any other language where people seem to be confused about pass by value vs. pass by reference.

Clearly, PHP, like C++, is a language that does support pass by reference. By default, objects are passed by value. When working with variables that store objects, it helps to see those variables as pointers (because that is fundamentally what they are, at the assembly level). If you pass a pointer by value, you can still "trace" the pointer and modify the properties of the object being pointed to. What you cannot do is have it point to a different object. Only if you explicitly declare a parameter as being passed by reference will you be able to do that.

There is another case where the two possibilities differ, on top of those already mentioned: if you need to call a non-public constructor (protected or private), make_shared might not be able to access it, while the variant with the new works fine.

class A
{
public:

    A(): val(0){}

    std::shared_ptr<A> createNext(){ return std::make_shared<A>(val+1); }
    // Invalid because make_shared needs to call A(int) **internally**

    std::shared_ptr<A> createNext(){ return std::shared_ptr<A>(new A(val+1)); }
    // Works fine because A(int) is called explicitly

private:

    int val;

    A(int v): val(v){}
};

Combining previous answers with finding the container ID based on the Docker image name:

docker inspect --format '{{ .NetworkSettings.IPAddress }}' `docker ps | grep $IMAGE_NAME | sed 's/\|/ /' | awk '{print $1}'`

The solution is the /Y switch:

xcopy "C:\Users\ADMIN\Desktop\*.*" "D:\Backup\" /K /D /H /Y

namespace std
{
    inline string to_string(int _Val)
    {   // Convert long long to string
        char _Buf[2 * _MAX_INT_DIG];
        snprintf(_Buf, "%d", _Val);
        return (string(_Buf));
    }
}

You can now use to_string(5).

Or like this:

Code::whereNotIn('to_be_used_by_user_id', [2])->get();

I would like to propose a generalization with awk.

When the file is made by blocks of a fixed size and the lines to delete are repeated for each block, awk can work fine in such a way

awk '{nl=((NR-1)%2000)+1; if ( (nl<714) || ((nl>1025)&&(nl<1029)) ) print  $0}'
 OriginFile.dat > MyOutputCuttedFile.dat

In this example the size for the block is 2000 and I want to print the lines [1..713] and [1026..1029].

• NR is the variable used by awk to store the current line number.
• % gives the remainder (or modulus) of the division of two integers;
• nl=((NR-1)%BLOCKSIZE)+1 Here we write in the variable nl the line number inside the current block. (see below)
• || and && are the logical operator OR and AND.
• print $0 writes the full line

Why ((NR-1)%BLOCKSIZE)+1:
(NR-1) We need a shift of one because 1%3=1, 2%3=2, but 3%3=0.
  +1   We add again 1 because we want to restore the desired order.

+-----+------+----------+------------+
| NR  | NR%3 | (NR-1)%3 | (NR-1)%3+1 |
+-----+------+----------+------------+
|  1  |  1   |    0     |     1      |
|  2  |  2   |    1     |     2      |
|  3  |  0   |    2     |     3      |
|  4  |  1   |    0     |     1      |
+-----+------+----------+------------+

it is very simple and one line of code

<a href="#" title="delete" class="delete" onclick="return confirm('Are you sure you want to delete this item')">Delete</a>

python doc strings are free-form, you can document it in any way you like.

Examples:

def mymethod(self, foo, bars):
    """
    Does neat stuff!
    Parameters:
      foo - a foo of type FooType to bar with.
      bars - The list of bars
    """

Now, there are some conventions, but python doesn't enforce any of them. Some projects have their own conventions. Some tools to work with docstrings also follow specific conventions.

From CLI:

$ su - postgres 
$ psql template1
template1=# CREATE USER tester WITH PASSWORD 'test_password';
template1=# GRANT ALL PRIVILEGES ON DATABASE "test_database" to tester;
template1=# \q

PHP (as tested on localhost, it works as expected):

  $connString = 'port=5432 dbname=test_database user=tester password=test_password';
  $connHandler = pg_connect($connString);
  echo 'Connected to '.pg_dbname($connHandler);

UPDATE

Now it's easier than ever (Angular 1.3), just add a debounce option on the model.

<input type="text" ng-model="searchStr" ng-model-options="{debounce: 1000}">

Updated plunker:
http://plnkr.co/edit/4V13gK

Documentation on ngModelOptions:
https://docs.angularjs.org/api/ng/directive/ngModelOptions

Old method:

Here's another method with no dependencies beyond angular itself.

You need set a timeout and compare your current string with the past version, if both are the same then it performs the search.

$scope.$watch('searchStr', function (tmpStr)
{
  if (!tmpStr || tmpStr.length == 0)
    return 0;
   $timeout(function() {

    // if searchStr is still the same..
    // go ahead and retrieve the data
    if (tmpStr === $scope.searchStr)
    {
      $http.get('//echo.jsontest.com/res/'+ tmpStr).success(function(data) {
        // update the textarea
        $scope.responseData = data.res; 
      });
    }
  }, 1000);
});

and this goes into your view:

<input type="text" data-ng-model="searchStr">

<textarea> {{responseData}} </textarea>

.Net Core seems to be missing the DispatcherTimer.

If we are OK with using an async method, Task.Delay will meet our needs. This can also be useful if you want to wait inside of a for loop for rate-limiting reasons.

public async Task DoTasks(List<Items> items)
{
    foreach (var item in items)
    {
        await Task.Delay(2 * 1000);
        DoWork(item);
    }
}

You can await the completion of this method as follows:

public async void TaskCaller(List<Item> items)
{
    await DoTasks(items);
}

You might be looking for IgnoreDataMemberAttribute.

try this

json = $.grep(newcurrPayment.paymentTypeInsert, function (el, idx) { return el.FirstName == "Test1" }, true)

All the answers here suggest to use ipairs but beware, it does not work all the time.

t = {[2] = 44, [4]=77, [6]=88}

--This for loop prints the table
for key,value in next,t,nil do 
  print(key,value) 
end

--This one does not print the table
for key,value in ipairs(t) do 
  print(key,value) 
end

READ AT LEAST THE FIRST PARA HERE!

I know this is 3 years too late, but Matt's (accepted) answer is incomplete and will eventually get you into trouble. The key here is that, if you choose to use multipart/form-data, the boundary must not appear in the file data that the server eventually receives.

This is not a problem for application/x-www-form-urlencoded, because there is no boundary. x-www-form-urlencoded can also always handle binary data, by the simple expedient of turning one arbitrary byte into three 7BIT bytes. Inefficient, but it works (and note that the comment about not being able to send filenames as well as binary data is incorrect; you just send it as another key/value pair).

The problem with multipart/form-data is that the boundary separator must not be present in the file data (see RFC 2388; section 5.2 also includes a rather lame excuse for not having a proper aggregate MIME type that avoids this problem).

So, at first sight, multipart/form-data is of no value whatsoever in any file upload, binary or otherwise. If you don't choose your boundary correctly, then you will eventually have a problem, whether you're sending plain text or raw binary - the server will find a boundary in the wrong place, and your file will be truncated, or the POST will fail.

The key is to choose an encoding and a boundary such that your selected boundary characters cannot appear in the encoded output. One simple solution is to use base64 (do not use raw binary). In base64 3 arbitrary bytes are encoded into four 7-bit characters, where the output character set is [A-Za-z0-9+/=] (i.e. alphanumerics, '+', '/' or '='). = is a special case, and may only appear at the end of the encoded output, as a single = or a double ==. Now, choose your boundary as a 7-bit ASCII string which cannot appear in base64 output. Many choices you see on the net fail this test - the MDN forms docs, for example, use "blob" as a boundary when sending binary data - not good. However, something like "!blob!" will never appear in base64 output.

Issue

Here are a couple of things to notice in order to understand the connected component's behavior in your code:

The Arity of connect Matters: connect(mapStateToProps, mapDispatchToProps)

React-Redux calls connect with the first argument mapStateToProps, and second argument mapDispatchToProps.

Therefore, although you've passed in your mapDispatchToProps, React-Redux in fact treats that as mapState because it is the first argument. You still get the injected onSubmit function in your component because the return of mapState is merged into your component's props. But that is not how mapDispatch is supposed to be injected.

You may use mapDispatch without defining mapState. Pass in null in place of mapState and your component will not subject to store changes.

Connected Component Receives dispatch by Default, When No mapDispatch Is Provided

Also, your component receives dispatch because it received null for its second position for mapDispatch. If you properly pass in mapDispatch, your component will not receive dispatch.

Common Practice

The above answers why the component behaved that way. Although, it is common practice that you simply pass in your action creator using mapStateToProps's object shorthand. And call that within your component's onSubmit That is:

import { setAddresses } from '../actions.js'

const Start = (props) => {
  // ... omitted
  return <div>
    {/** omitted */}
    <FlatButton 
       label='Does Not Work'
       onClick={this.props.setAddresses({
         pickup: this.refs.pickup.state.address,
         dropoff: this.refs.dropoff.state.address
       })} 
    />
  </div>
};

const mapStateToProps = { setAddresses };
export default connect(null, mapDispatchToProps)(Start)

I was getting this exception when debugging in PyCharm, given that no breakpoint was being hit. To prevent it, I added a breakpoint just after the with block, and then it stopped happening.

In very laymen terms the class is a mold and the object is the copy made with that mold. Static belong to the mold and can be accessed directly without making any copies, hence the example above

Perl one-liner would be a simple version of Maxim's solution

perl -MList::Util=shuffle -e 'print shuffle(<STDIN>);' < myfile

Your countLines(String filename) method throws IOException.

You can't use it in a member declaration. You'll need to perform the operation in a main(String[] args) method.

Your main(String[] args) method will get the IOException thrown to it by countLines and it will need to handle or declare it.

Try this to just throw the IOException from main

public class MyClass {
  private int lineCount;
  public static void main(String[] args) throws IOException {
    lineCount = LineCounter.countLines(sFileName);
  }
}

or this to handle it and wrap it in an unchecked IllegalArgumentException:

public class MyClass {
  private int lineCount;
  private String sFileName  = "myfile";
  public static void main(String[] args) throws IOException {
    try {
      lineCount = LineCounter.countLines(sFileName);
     } catch (IOException e) {
       throw new IllegalArgumentException("Unable to load " + sFileName, e);
     }
  }
}

Yes! By passing a stream context in the third parameter:

This has really puzzled me for a while but this is what I found in the end.

When you call, sc.close() in first method, it not only closes your scanner but closes your System.in input stream as well. You can verify it by printing its status at very top of the second method as :

    System.out.println(System.in.available());

So, now when you re-instantiate, Scanner in second method, it doesn't find any open System.in stream and hence the exception.

I doubt if there is any way out to reopen System.in because:

public void close() throws IOException --> Closes this input stream and releases any system resources associated with this stream. The general contract of close is that it closes the input stream. A closed stream cannot perform input operations and **cannot be reopened.**

The only good solution for your problem is to initiate the Scanner in your main method, pass that as argument in your two methods, and close it again in your main method e.g.:

main method related code block:

Scanner scanner = new Scanner(System.in);  

// Ask users for quantities 
PromptCustomerQty(customer, ProductList, scanner );

// Ask user for payment method
PromptCustomerPayment(customer, scanner );

//close the scanner 
scanner.close();

Your Methods:

 public static void PromptCustomerQty(Customer customer, 
                             ArrayList<Product> ProductList, Scanner scanner) {

    // no more scanner instantiation
    ...
    // no more scanner close
 }


 public static void PromptCustomerPayment (Customer customer, Scanner sc) {

    // no more scanner instantiation
    ...
    // no more scanner close
 }

Hope this gives you some insight about the failure and possible resolution.

I still think after Java 1.5, enum is the best available singleton implementation available as it also ensures that, even in the multi threaded environments, only one instance is created.

public enum Singleton {
    INSTANCE;
}

And you are done!

Solution is here:

SomeModel.last(5).reverse

Since rails is lazy, it will eventually hit the database with SQL like: "SELECT table.* FROM table ORDER BY table.id DESC LIMIT 5".

Updated:

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

Original answer:

# Create a backup of master branch
git branch backup_master

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

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

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

# Delete unused branch
git branch -d backup_master

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

You declared them, but you didn't initialize them. Initializing them is setting them equal to a value:

int a;        // This is a declaration
a = 0;        // This is an initialization
int b = 1;    // This is a declaration and initialization

You get the error because you haven't initialized the variables, but you increment them (e.g., a++) in the for loop.

Java primitives have default values but as one user commented below

Their default value is zero when declared as class members. Local variables don't have default values

Go to obj folder in you app folder, then Debug. In there delete the manifest file and build again. It worked for me.

Another way to do this is by using the bitstring module:

>>> from bitstring import BitArray
>>> input_str = '0xff'
>>> c = BitArray(hex=input_str)
>>> c.bin
'0b11111111'

And if you need to strip the leading 0b:

>>> c.bin[2:]
'11111111'

The bitstring module isn't a requirement, as jcollado's answer shows, but it has lots of performant methods for turning input into bits and manipulating them. You might find this handy (or not), for example:

>>> c.uint
255
>>> c.invert()
>>> c.bin[2:]
'00000000'

etc.

In some ways, your question seems very legitimate, but I still might label it an XY problem. I'm guessing the end result is that you want to display the sorted values in some way? As Bergi said in the comments, you can never quite rely on Javascript objects ( {i_am: "an_object"} ) to show their properties in any particular order.

For the displaying order, I might suggest you take each key of the object (ie, i_am) and sort them into an ordered array. Then, use that array when retrieving elements of your object to display. Pseudocode:

var keys = [...]
var sortedKeys = [...]
for (var i = 0; i < sortedKeys.length; i++) {
  var key = sortedKeys[i];
  addObjectToTable(json[key]);
}

The accepted solution of modifying a Run Configuration wasn't ideal for me as I have a few different run configurations and could easily forget to do this when adding further ones in future. Also I wanted the setting to apply whenever running anything, e.g. when running JUnit tests by right-clicking and selecting "Run As" -> "JUnit Test".

The above can be achieved by modifying the JRE/JDK settings instead:-

1. Go to Window -> Preferences.
2. Select Java -> Installed JREs
3. Select your default JRE (which could be a JDK) and click on "Edit..."
4. Change the "Default VM arguments" value as required, e.g. -Xms512m -Xmx4G -XX:MaxPermSize=256M

It's simply “No such directory entry”. Since directory entries can be directories or files (or symlinks, or sockets, or pipes, or devices), the name ENOFILE would have been too narrow in its meaning.

There are various methods for collision resolution.Some of them are Separate Chaining,Open addressing,Robin Hood hashing,Cuckoo Hashing etc.

Java uses Separate Chaining for resolving collisions in Hash tables.Here is a great link to how it happens: http://javapapers.com/core-java/java-hashtable/

Similar to the answer before there there is

location.host

The location global has more fun facts about the current url as well. ( protocol, host, port, pathname, search, hash )

I have created a utility function (tested once on a device where I was getting an incorrect country code based on locale).

Reference: CountryCodePicker.java

fun getDetectedCountry(context: Context, defaultCountryIsoCode: String): String {

    detectSIMCountry(context)?.let {
        return it

    detectNetworkCountry(context)?.let {
        return it
    }

    detectLocaleCountry(context)?.let {
        return it
    }

    return defaultCountryIsoCode
}

private fun detectSIMCountry(context: Context): String? {
    try {
        val telephonyManager = context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
        Log.d(TAG, "detectSIMCountry: ${telephonyManager.simCountryIso}")
        return telephonyManager.simCountryIso
    }
    catch (e: Exception) {
        e.printStackTrace()
    }
    return null
}

private fun detectNetworkCountry(context: Context): String? {
    try {
        val telephonyManager = context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
        Log.d(TAG, "detectNetworkCountry: ${telephonyManager.simCountryIso}")
        return telephonyManager.networkCountryIso
    }
    catch (e: Exception) {
        e.printStackTrace()
    }
    return null
}

private fun detectLocaleCountry(context: Context): String? {
    try {
        val localeCountryISO = context.getResources().getConfiguration().locale.getCountry()
        Log.d(TAG, "detectNetworkCountry: $localeCountryISO")
        return localeCountryISO
    }
    catch (e: Exception) {
        e.printStackTrace()
    }
    return null

That syntax should work OK, but you can try this alternative.

let localURL = URL.init(fileURLWithPath: Bundle.main.path(forResource: "index", ofType: "html", inDirectory: "CWP")!)
myWebView.load(NSURLRequest.init(url: localURL) as URLRequest)

This adjusts for some of the finer syntax changes in 3.01 and keeps the directory structure in place so you can embed related HTML files.

Use this code:

'{:x}'.format(int(line))

it allows you to specify a number of digits too:

'{:06x}'.format(123)
# '00007b'

For Python 2.6 use

'{0:x}'.format(int(line))

or

'{0:06x}'.format(int(line))

You can disable/enable pagers for specific outputs in the global configuration as well:

git config --global pager.diff false

Or to set the core.pager option, just provide an empty string:

git config --global core.pager ''

This is better in my opinion than setting it to cat as you say.

p is a pointer variable. Its value is the address of i. When you call f, you pass the value of p, which is the address of i.

You could write it like this:

switch (varName)
{
   case "afshin": 
   case "saeed": 
   case "larry": 
       alert('Hey');
       break;

   default: 
       alert('Default case');
       break;
}         

ThreadLocal is a specially provisioned functionality by JVM to provide an isolated storage space for threads only. like the value of instance scoped variable are bound to a given instance of a class only. each object has its only values and they can not see each other value. so is the concept of ThreadLocal variables, they are local to the thread in the sense of object instances other thread except for the one which created it, can not see it. See Here

import java.util.concurrent.atomic.AtomicInteger;
import java.util.stream.IntStream;


public class ThreadId {
private static final AtomicInteger nextId = new AtomicInteger(1000);

// Thread local variable containing each thread's ID
private static final ThreadLocal<Integer> threadId = ThreadLocal.withInitial(() -> nextId.getAndIncrement());


// Returns the current thread's unique ID, assigning it if necessary
public static int get() {
    return threadId.get();
}

public static void main(String[] args) {

    new Thread(() -> IntStream.range(1, 3).forEach(i -> {
        System.out.println(Thread.currentThread().getName() + " >> " + new ThreadId().get());
    })).start();

    new Thread(() -> IntStream.range(1, 3).forEach(i -> {
        System.out.println(Thread.currentThread().getName() + " >> " + new ThreadId().get());
    })).start();

    new Thread(() -> IntStream.range(1, 3).forEach(i -> {
        System.out.println(Thread.currentThread().getName() + " >> " + new ThreadId().get());
    })).start();

}
}

You could specify the dtype directly when constructing the DataFrame:

>>> df = pd.DataFrame(index=range(0,4),columns=['A'], dtype='float')
>>> df.dtypes
A    float64
dtype: object

Specifying the dtype forces Pandas to try creating the DataFrame with that type, rather than trying to infer it.

You can use an event listener to close the clip after it is played

import java.io.File;
import javax.sound.sampled.*;

public void play(File file) 
{
    try
    {
        final Clip clip = (Clip)AudioSystem.getLine(new Line.Info(Clip.class));

        clip.addLineListener(new LineListener()
        {
            @Override
            public void update(LineEvent event)
            {
                if (event.getType() == LineEvent.Type.STOP)
                    clip.close();
            }
        });

        clip.open(AudioSystem.getAudioInputStream(file));
        clip.start();
    }
    catch (Exception exc)
    {
        exc.printStackTrace(System.out);
    }
}

For years I used Hungarian notation in my programming. Other than some visual clutter and the task of changing the prefix when I changed the data type, no one could convince me otherwise. Until recently--when I had to combine existing C# and VB.NET assemblies in the same solution.

The result: I had to pass a "fltSomeVariable" to a "sngSomeVariable" method parameter. Even as someone who programs in both C# and VB.NET, it caught me off guard and made me pause for a moment. (C# and VB.NET sometimes use different names to represent the same data type--float and single, for example.)

Now consider this: what if you create a COM component that's callable from many languages? The VB.NET and C# "conversion" was easy for a .NET programmer. But what about someone that develops in C++ or Java? Does "dwSomeVariable" mean anything to a .NET developer not familiar with C++?

I had this error because I was providing a string of arguments to subprocess.call instead of an array of arguments. To prevent this, use shlex.split:

import shlex, subprocess
command_line = "ls -a"
args = shlex.split(command_line)
p = subprocess.Popen(args)

@JsonFormat only work for standard format supported by the jackson version that you are using.

Ex :- compatible with any of standard forms ("yyyy-MM-dd'T'HH:mm:ss.SSSZ", "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "EEE, dd MMM yyyy HH:mm:ss zzz", "yyyy-MM-dd")) for jackson 2.8.6

You can simply change the name of the file by changing the name of the file in the second parameter of move_uploaded_file.

Instead of

move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $_FILES["file"]["name"]);

Use

$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = round(microtime(true)) . '.' . end($temp);
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename);

Changed to reflect your question, will product a random number based on the current time and append the extension from the originally uploaded file.

Try this,

alter table goods add column `id` int(10) unsigned primary key auto_increment

setTimeout(callback,t) is used to run callback after at least t millisecond. The actual delay depends on many external factors like OS timer granularity and system load.

So, there is a possibility that it will be called slightly after the set time, but will never be called before.

A timer can't span more than 24.8 days.

You can use Include Directives

<%
 if(request.getParameter("p")!=null)
 { 
   String p = request.getParameter("p");
%>    

<%@include file="<%="includes/" + p +".jsp"%>"%>

<% 
 }
%>

or JSP Include Action

<%
 if(request.getParameter("p")!=null)
 { 
   String p = request.getParameter("p");
%>    

<jsp:include page="<%="includes/"+p+".jsp"%>"/>

<% 
 }
%>

the different is include directive includes a file during the translation phase. while JSP Include Action includes a file at the time the page is requested

I recommend Spring MVC Framework as your controller to manipulate things. use url pattern instead of parameter.

example:

www.yourwebsite.com/products

instead of

www.yourwebsite.com/?p=products

Watch this video Spring MVC Framework

Are you explicitly setting the values as blank? For example:

<input type="text" name="textfield" value="">

That should stop browsers putting data in where it shouldn't. Alternatively, you can add the autocomplete attribute to the form tag:

<form autocomplete="off" ...></form>

let firstname = "paresh"
let lastname = "hirpara"
let itsme = "\(firstname) \(lastname)"

Here is a simpler way to iterate and print values in vector.

for(int x: A) // for integer x in vector A
    cout<< x <<" "; 

e is the short var reference for event object which will be passed to event handlers.

The event object essentially has lot of interesting methods and properties that can be used in the event handlers.

In the example you have posted is a click handler which is a MouseEvent

$(<element selector>).click(function(e) {
    // does something
    alert(e.type); //will return you click
}

DEMO - Mouse Events DEMO uses e.which and e.type

There are two methods to consider which achieve the same effect for handling null pointers to C-style strings.

The ternary operator

void setvalue(const char *value)
{
    std::string mValue = value ? value : "";

}

or the humble if statement

void setvalue(const char *value)
{
    std::string mValue;
    if(value) mValue = value;

}

In both cases, value is only assigned to mValue when value is not a null pointer. In all other cases (i.e. when value is null), mValue will contain an empty string.

The ternary operator method may be useful for providing an alternative default string literal in the absence of a value from value:

std::string mValue = value ? value : "(NULL)";

I suggest using pubnub. I tried using ServiceWorkers and PushNotification from the browser however, however when I tried it webviews did not support this.

https://www.pubnub.com/docs/web-javascript/pubnub-javascript-sdk

 WebConfigurationManager.ConnectionStrings["YourConnectionString"].ProviderName;

$rootScope is a big global variable, which is fine for one-off things, or small apps. Use a service if you want to encapsulate your model and/or behavior (and possibly reuse it elsewhere). In addition to the google group post the OP mentioned, see also https://groups.google.com/d/topic/angular/eegk_lB6kVs/discussion.

Very old question, but I tried everything suggested above and still could not get it resolved.

Turns out that, I had after insert/update trigger for the main table which tracked the changes by inserting the record in history table having similar structure. I increased the size in the main table column but forgot to change the size of history table column and that created the problem.

I did similar changes in the other table and error is gone.

Swift 4 Examples

Example #1 using closure

NotificationCenter.default.addObserver(forName: .UIApplicationUserDidTakeScreenshot, 
                                       object: nil, 
                                       queue: OperationQueue.main) { notification in
    print("\(notification) that a screenshot was taken!")
}

Example #2 with selector

NotificationCenter.default.addObserver(self, 
                                       selector: #selector(screenshotTaken), 
                                       name: .UIApplicationUserDidTakeScreenshot, 
                                       object: nil)

@objc func screenshotTaken() {
    print("Screenshot taken!")
}

For http connections, the WebRequest and WebResponse classes use SSL to communicate with web hosts that support SSL. The decision to use SSL is made by the WebRequest class, based on the URI it is given. If the URI begins with "https:", SSL is used; if the URI begins with "http:", an unencrypted connection is used.

Actually this is not really the same to import a variable with:

from file1 import x1
print(x1)

and

import file1
print(file1.x1)

Altough at import time x1 and file1.x1 have the same value, they are not the same variables. For instance, call a function in file1 that modifies x1 and then try to print the variable from the main file: you will not see the modified value.

Session.Abandon() destroys the session and the Session_OnEnd event is triggered.

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive.

So, if you use Session.Abandon(), you lose that specific session and the user will get a new session key. You could use it for example when the user logs out.

Use Session.Clear(), if you want that the user remaining in the same session (if you don't want the user to relogin for example) and reset all the session specific data.

Apparently random.sample was introduced in python 2.3

so for version under that, we can use shuffle (example for 4 items):

myRange =  range(0,len(mylist)) 
shuffle(myRange)
coupons = [ bestCoupons[i] for i in sorted(myRange[:4]) ]

Schema information which is designed to be very close to that of the SQL-92 INFORMATION_SCHEMA may be obtained for the Jet/ACE engine (which is what I assume you mean by 'access') via the OLE DB providers.

See:

OpenSchema Method (ADO)

Supported Schema Rowsets

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.calendar, menu);
        if(show_list == true) {         

        if(!locale.equalsIgnoreCase("sk")) menu.findItem(R.id.action_cyclesn).setVisible(false);

        return true;
    }

Proper jdbc call should look something like:

try { 
    Connection conn;
    Statement stmt;
    ResultSet rs; 

    try {
        conn = DriverManager.getConnection(myUrl,"",""); 
        stmt = conn.createStatement(); 
        rs = stmt.executeQuery(myQuery); 

        while ( rs.next() ) { 
            // process results
        } 

    } catch (SqlException e) { 
        System.err.println("Got an exception! "); 
        System.err.println(e.getMessage()); 
    } finally {
        // you should release your resources here
        if (rs != null) { 
            rs.close();
        }

        if (stmt != null) {
            stmt.close();
        }

        if (conn != null) {
            conn.close();
        }
    }
} catch (SqlException e) {
    System.err.println("Got an exception! "); 
    System.err.println(e.getMessage()); 
}

you can close connection (or statement) only after you get result from result set. Safest way is to do it in finally block. However close() could also throe SqlException, hence the other try-catch block.

Dirty checkedness

This concept provides an example where the difference is observable: http://www.w3.org/TR/html5/forms.html#concept-input-checked-dirty

Try it out:

• click the button. Both checkboxes got checked.
• uncheck both checkboxes.
• click the button again. Only the prop checkbox got checked. BANG!

$('button').on('click', function() {_x000D_
  $('#attr').attr('checked', 'checked')_x000D_
  $('#prop').prop('checked', true)_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<label>attr <input id="attr" type="checkbox"></label>_x000D_
<label>prop <input id="prop" type="checkbox"></label>_x000D_
<button type="button">Set checked attr and prop.</button>

For some attributes like disabled on button, adding or removing the content attribute disabled="disabled" always toggles the property (called IDL attribute in HTML5) because http://www.w3.org/TR/html5/forms.html#attr-fe-disabled says:

The disabled IDL attribute must reflect the disabled content attribute.

so you might get away with it, although it is ugly since it modifies HTML without need.

For other attributes like checked="checked" on input type="checkbox", things break, because once you click on it, it becomes dirty, and then adding or removing the checked="checked" content attribute does not toggle checkedness anymore.

This is why you should use mostly .prop, as it affects the effective property directly, instead of relying on complex side-effects of modifying the HTML.

QEMU has a fantastic utility called qmeu-img that will translate between all manner of disk image formats. An article on this process is at http://thedarkmaster.wordpress.com/2007/03/12/vmware-virtual-machine-to-virtual-box-conversion-how-to/

I recall in my head that I used qemu-img to roll multiple VMDKs into one, but I don't have that computer with me to retest the process. Even if I'm wrong, the article above includes a section that describes how to convert them with your VMWare tools.

This worked form me.. PHP Code on page.php

 $query_de="sql statements here";
 $sql_de = sqlsrv_query($conn,$query_de);
      if ($sql_de)
      {
        echo "SQLSuccess";
       }
         exit();

and then AJAX Code has bellow

jQuery.ajax({
                    url  : "page.php",
                    type : "POST",
                    data : {
                            buttonsave   : 1,
                            var1         : val1,
                            var2         : val2,
                              },
                  success:function(data)
                           {
                     if(jQuery.trim(data) === "SQLSuccess")
                                   {
                           alert("Se agrego correctamente");
                          // alert(data);
                                      } else { alert(data);}
                              },
                   error: function(error)
                           {
                    alert("Error AJAX not working: "+ error );
                              } 
               }); 

NOTE: the word 'SQLSuccess' must be received from PHP

that the OpenSSL extension enabled and the directory languages with "br"? first checks the data.

I had the same problem. The reason - wrong proxy was configured and because of that npm was unable to download packages.

So your best bet is to the see the output of

$ npm install --verbose

and identify the problem. If you have never configured proxy, then possible causes can be

• Very outdated npm version.
• Some problem with your internet connection.
• Permissions are not sufficient for npm to modify files.

ps -fC PROCESSNAME

ps and grep is a dangerous combination -- grep tries to match everything on each line (thus the all too common: grep -v grep hack). ps -C doesn't use grep, it uses the process table for an exact match. Thus, you'll get an accurate list with: ps -fC sh rather finding every process with sh somewhere on the line.

Change your code to the following :

Function Foo($directory)
    {
        echo $directory
    }

    if ($args.Length -eq 0)
    {
        echo "Usage: Foo <directory>"
    }
    else
    {
        Foo([string[]]$args)
    }

And then invoke it as:

powershell -ExecutionPolicy RemoteSigned -File "c:\foo.ps1" "c:\Documents and Settings" "c:\test"

Old question and all of that. But this is yet another way that offers some advantages.

On Windows, you could ask the task scheduler to start your app again for you. This has the advantage of waiting a specific amount of time before the app is restarted. You can go to task manager and delete the task and it stops repeating.

SimpleDateFormat hhmm = new SimpleDateFormat("kk:mm");    
Calendar aCal = Calendar.getInstance(); 
aCal.add(Calendar.SECOND, 65);
String nextMinute = hhmm.format(aCal.getTime()); //Task Scheduler Doesn't accept seconds and won't do current minute.
String[] create = {"c:\\windows\\system32\\schtasks.exe", "/CREATE", "/F", "/TN", "RestartMyProg", "/SC", "ONCE", "/ST", nextMinute, "/TR", "java -jar c:\\my\\dev\\RestartTest.jar"};  
Process proc = Runtime.getRuntime().exec(create, null, null);
System.out.println("Exit Now");
try {Thread.sleep(1000);} catch (Exception e){} // just so you can see it better
System.exit(0);

You can use the properties tab in eclipse to set various values.

It can be done in bash itself if you have control of the configuration file format. You just need to source (".") the configuration file rather than subshell it. That ensures the variables are created in the context of the current shell (and continue to exist) rather than the subshell (where the variable disappear when the subshell exits).

$ cat config.data
    export parm_jdbc=jdbc:db2://box7.co.uk:5000/INSTA
    export parm_user=pax
    export parm_pwd=never_you_mind

$ cat go.bash
    . config.data
    echo "JDBC string is " $parm_jdbc
    echo "Username is    " $parm_user
    echo "Password is    " $parm_pwd

$ bash go.bash
    JDBC string is  jdbc:db2://box7.co.uk:5000/INSTA
    Username is     pax
    Password is     never_you_mind

If your config file cannot be a shell script, you can just 'compile' it before executing thus (the compilation depends on your input format).

$ cat config.data
    parm_jdbc=jdbc:db2://box7.co.uk:5000/INSTA # JDBC URL
    parm_user=pax                              # user name
    parm_pwd=never_you_mind                    # password

$ cat go.bash
    cat config.data
        | sed 's/#.*$//'
        | sed 's/[ \t]*$//'
        | sed 's/^[ \t]*//'
        | grep -v '^$'
        | sed 's/^/export '
        >config.data-compiled
    . config.data-compiled
    echo "JDBC string is " $parm_jdbc
    echo "Username is    " $parm_user
    echo "Password is    " $parm_pwd

$ bash go.bash
    JDBC string is  jdbc:db2://box7.co.uk:5000/INSTA
    Username is     pax
    Password is     never_you_mind

In your specific case, you could use something like:

$ cat config.data
    export p_p1=val1
    export p_p2=val2
$ cat go.bash
    . ./config.data
    echo "select * from dbtable where p1 = '$p_p1' and p2 like '$p_p2%' order by p1"
$ bash go.bash
    select * from dbtable where p1 = 'val1' and p2 like 'val2%' order by p1

Then pipe the output of go.bash into MySQL and voila, hopefully you won't destroy your database :-).

Three ways to check if a property is present in a javascript object:

1. !!obj.theProperty
   Will convert value to bool. returns true for all but the false value
2. 'theProperty' in obj
   Will return true if the property exists, no matter its value (even empty)
3. obj.hasOwnProperty('theProperty')
   Does not check the prototype chain. (since all objects have the toString method, 1 and 2 will return true on it, while 3 can return false on it.)

Reference:

http://book.mixu.net/node/ch5.html

First: As it currently stands, the $User variable does not have a .Users property. In your code, $User simply represents one line (the "current" line in the foreach loop) from the text file.

$getmembership = Get-ADUser $User -Properties MemberOf | Select -ExpandProperty memberof

Secondly, I do not believe you can query an entire forest with one command. You will have to break it down into smaller chunks:

1. Query forest for list of domains
2. Call Get-ADUser for each domain (you may have to specify alternate credentials via the -Credential parameter

Thirdly, to get a list of groups that a user is a member of:

$User = Get-ADUser -Identity trevor -Properties *;
$GroupMembership = ($user.memberof | % { (Get-ADGroup $_).Name; }) -join ';';

# Result:
Orchestrator Users Group;ConfigMgr Administrators;Service Manager Admins;Domain Admins;Schema Admins

Fourthly: To get the final, desired string format, simply add the $User.Name, a semicolon, and the $GroupMembership string together:

$User.SamAccountName + ';' + $GroupMembership;

This is the new way to do it:

Path root = FileSystems.getDefault().getPath("").toAbsolutePath();
Path filePath = Paths.get(root.toString(),"src", "main", "resources", fileName);

Or even better:

Path root = Paths.get(".").normalize().toAbsolutePath();

But I would take it one step further:

public String getUsersProjectRootDirectory() {
    String envRootDir = System.getProperty("user.dir");
    Path rootDIr = Paths.get(".").normalize().toAbsolutePath();
    if ( rootDir.startsWith(envRootDir) ) {
        return rootDir;
    } else {
        throw new RuntimeException("Root dir not found in user directory.");
    }
}

The documentation (https://angular.io/guide/template-syntax#!#star-template) gives the following example. Say we have template code like this:

<hero-detail *ngIf="currentHero" [hero]="currentHero"></hero-detail>

Before it will be rendered, it will be "de-sugared". That is, the asterix notation will be transcribed to the notation:

<template [ngIf]="currentHero">
  <hero-detail [hero]="currentHero"></hero-detail>
</template>

If 'currentHero' is truthy this will be rendered as

<hero-detail> [...] </hero-detail>

But what if you want an conditional output like this:

<h1>Title</h1><br>
<p>text</p>

.. and you don't want the output be wrapped in a container.

You could write the de-sugared version directly like so:

<template [ngIf]="showContent">
  <h1>Title</h1>
  <p>text</p><br>
</template>

And this will work fine. However, now we need ngIf to have brackets [] instead of an asterix *, and this is confusing (https://github.com/angular/angular.io/issues/2303)

For that reason a different notation was created, like so:

<ng-container *ngIf="showContent"><br>
  <h1>Title</h1><br>
  <p>text</p><br>
</ng-container>

Both versions will produce the same results (only the h1 and p tag will be rendered). The second one is preferred because you can use *ngIf like always.

Please read and strongly consider my advice in the comments of your post. That being said, if you still have a good reason to do this, check out this list of crypto modules for Node. It has modules for dealing with both sha1 and base64.

It's simple. Do this, in your Manifest file.

<activity
    android:name="Your app name"
    android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.HOME" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
</activity>

The Servlet Specification JSR-315 clearly defines the web container behavior in the service (and doGet, doPost, doPut etc.) methods (2.3.3.1 Multithreading Issues, Page 9):

A servlet container may send concurrent requests through the service method of the servlet. To handle the requests, the Servlet Developer must make adequate provisions for concurrent processing with multiple threads in the service method.

Although it is not recommended, an alternative for the Developer is to implement the SingleThreadModel interface which requires the container to guarantee that there is only one request thread at a time in the service method. A servlet container may satisfy this requirement by serializing requests on a servlet, or by maintaining a pool of servlet instances. If the servlet is part of a Web application that has been marked as distributable, the container may maintain a pool of servlet instances in each JVM that the application is distributed across.

For servlets not implementing the SingleThreadModel interface, if the service method (or methods such as doGet or doPost which are dispatched to the service method of the HttpServlet abstract class) has been defined with the synchronized keyword, the servlet container cannot use the instance pool approach, but must serialize requests through it. It is strongly recommended that Developers not synchronize the service method (or methods dispatched to it) in these circumstances because of detrimental effects on performance

To use AWK to cut off the first and last fields:

awk '{$1 = ""; $NF = ""; print}' inputfile

Unfortunately, that leaves the field separators, so

aaa bbb ccc

becomes

[space]bbb[space]

To do this using kurumi's answer which won't leave extra spaces, but in a way that's specific to your requirements:

awk '{delim = ""; for (i=2;i<=NF-1;i++) {printf delim "%s", $i; delim = OFS}; printf "\n"}' inputfile

This also fixes a couple of problems in that answer.

To generalize that:

awk -v skipstart=1 -v skipend=1 '{delim = ""; for (i=skipstart+1;i<=NF-skipend;i++) {printf delim "%s", $i; delim = OFS}; printf "\n"}' inputfile

Then you can change the number of fields to skip at the beginning or end by changing the variable assignments at the beginning of the command.

With Spring it's easy. Be it a file, or folder, or even multiple files, there are chances, you can do it via injection.

This example demonstrates the injection of multiple files located in x/y/z folder.

import org.springframework.beans.factory.annotation.Value;
import org.springframework.core.io.Resource;
import org.springframework.stereotype.Service;

@Service
public class StackoverflowService {
    @Value("classpath:x/y/z/*")
    private Resource[] resources;

    public List<String> getResourceNames() {
        return Arrays.stream(resources)
                .map(Resource::getFilename)
                .collect(Collectors.toList());
    }
}

It does work for resources in the filesystem as well as in JARs.

You can declare as many Exceptions as you want for your interface method. But the class you gave in your question is invalid. It should read

public class MyClass implements MyInterface {
  public void find(int x) throws A_Exception, B_Exception{
    ----
    ----
    ---
  }
}

Then an interface would look like this

public interface MyInterface {
  void find(int x) throws A_Exception, B_Exception;
}

Just add the following to your html code (withing the <head>) and you are done.

HTML:

<style>
      tr:nth-of-type(odd) {
      background-color:#ccc;
    }
</style>

Easier and faster than jQuery examples.

You can use Popen, and then you can check the procedure's status:

from subprocess import Popen

proc = Popen(['ls', '-l'])
if proc.poll() is None:
    proc.kill()

Check out subprocess.Popen.

replace

[bash:~] $ sudo update-alternatives --install /usr/bin/python python \
/usr/bin/python2.7 2

[bash:~] $ sudo update-alternatives --install /usr/bin/python python \

with

[bash:~] $ sudo update-alternatives --install /usr/local/bin/python python \
/usr/bin/python2.7 2

[bash:~] $ sudo update-alternatives --install /usr/local/bin/python python \
/usr/bin/python3.5 3

e.g. installing into /usr/local/bin instead of /usr/bin.

and ensure the /usr/local/bin is before /usr/bin in PATH.

i.e.

[bash:~] $ echo $PATH
/usr/local/bin:/usr/bin:/bin

Ensure this always is the case by adding

export PATH=/usr/local/bin:$PATH

to the end of your ~/.bashrc file. Prefixing the PATH environment variable with custom bin folder such as /usr/local/bin or /opt/<some install>/bin is generally recommended to ensure that customizations are found before the default system ones.

The various overloads of Runtime.getRuntime().exec(...) take either an array of strings or a single string. The single-string overloads of exec() will tokenise the string into an array of arguments, before passing the string array onto one of the exec() overloads that takes a string array. The ProcessBuilder constructors, on the other hand, only take a varargs array of strings or a List of strings, where each string in the array or list is assumed to be an individual argument. Either way, the arguments obtained are then joined up into a string that is passed to the OS to execute.

So, for example, on Windows,

Runtime.getRuntime().exec("C:\DoStuff.exe -arg1 -arg2");

will run a DoStuff.exe program with the two given arguments. In this case, the command-line gets tokenised and put back together. However,

ProcessBuilder b = new ProcessBuilder("C:\DoStuff.exe -arg1 -arg2");

will fail, unless there happens to be a program whose name is DoStuff.exe -arg1 -arg2 in C:\. This is because there's no tokenisation: the command to run is assumed to have already been tokenised. Instead, you should use

ProcessBuilder b = new ProcessBuilder("C:\DoStuff.exe", "-arg1", "-arg2");

or alternatively

List<String> params = java.util.Arrays.asList("C:\DoStuff.exe", "-arg1", "-arg2");
ProcessBuilder b = new ProcessBuilder(params);

import the module

import pandas as pd
import oursql

connect

conn=oursql.connect(host="localhost",user="me",passwd="mypassword",db="classicmodels")
sql="Select customerName, city,country from customers order by customerName,country,city"
df_mysql = pd.read_sql(sql,conn)
print df_mysql

That works just fine and using pandas.io.sql frame_works (with the deprecation warning). Database used is the sample database from mysql tutorial.

Some of the "getResourceAsStream()" options in this answer didn't work for me, but this one did:

SomeClassWithinYourSourceDir.class.getClassLoader().getResourceAsStream("yourResource");

I used a function to get current datetime

 protected function getCurrentDate()
    {
        $now = Carbon::now();
        return $now->toDateTimeString('');
    }

However I get an error.

Carbon\Exceptions\UnitException
Precision unit expected among: minute, second, millisecond and microsecond.

Any ideas how to get the time in a format like day.month.Year Hour:minute

The easiest way would be to set the main thread to sleep 3000 milliseconds (3 seconds):

for(int i = 0; i< 10; i++) {
    try {
        //sending the actual Thread of execution to sleep X milliseconds
        Thread.sleep(3000);
    } catch(InterruptedException ie) {}
    System.out.println("Hello world!"):
}

This will stop the thread at least X milliseconds. The thread could be sleeping more time, but that's up to the JVM. The only thing guaranteed is that the thread will sleep at least those milliseconds. Take a look at the Thread#sleep doc:

Causes the currently executing thread to sleep (temporarily cease execution) for the specified number of milliseconds, subject to the precision and accuracy of system timers and schedulers.

it worked. Just modified it

global $woocommerce, $post;

$order = new WC_Order($post->ID);

//to escape # from order id 

$order_id = trim(str_replace('#', '', $order->get_order_number()));

int main()
{
  int array[11];
  printf("Write down your ID number!\n");
  for(int i=0;i<id_length;i++)
  scanf("%d", &array[i]);
  if (array[0]==1)
  {
    printf("\nThis person is a male.");
  }
  else if (array[0]==2)
  {
    printf("\nThis person is a female.");
  }
  return 0;
}

(1) Is it possible to pass a JSON object to the url like in Ex.2?

No, because http://localhost:8080/api/v1/mno/objectKey/{"id":1, "name":"Saif"} is not a valid URL.

If you want to do it the RESTful way, use http://localhost:8080/api/v1/mno/objectKey/1/Saif, and defined your method like this:

@RequestMapping(path = "/mno/objectKey/{id}/{name}", method = RequestMethod.GET)
public Book getBook(@PathVariable int id, @PathVariable String name) {
    // code here
}

(2) How can we pass and parse the parameters in Ex.1?

Just add two request parameters, and give the correct path.

@RequestMapping(path = "/mno/objectKey", method = RequestMethod.GET)
public Book getBook(@RequestParam int id, @RequestParam String name) {
    // code here
}

UPDATE (from comment)

What if we have a complicated parameter structure ?

"A": [ {
    "B": 37181,
    "timestamp": 1160100436,
    "categories": [ {
        "categoryID": 2653,
        "timestamp": 1158555774
    }, {
        "categoryID": 4453,
        "timestamp": 1158555774
    } ]
} ]

Send that as a POST with the JSON data in the request body, not in the URL, and specify a content type of application/json.

@RequestMapping(path = "/mno/objectKey", method = RequestMethod.POST, consumes = "application/json")
public Book getBook(@RequestBody ObjectKey objectKey) {
    // code here
}

Just in case someone makes the same error I did before stumbling on this page, that is, adding CSS reset rules (like the very popular reset by Eric Meyer used on millions of websites) after including bootstrap.

Also, perhaps I should point out that such reset won't be necessary with bootstrap given bootsrap actually implements the normalize.css v3.0.2 reset.

For those coming in 2018:

The ONLY Solution worked for me:

<?php

    if (ob_get_level() == 0) ob_start();
    for ($i = 0; $i<10; $i++){

        echo "<br> Line to show.";
        echo str_pad('',4096)."\n";    

        ob_flush();
        flush();
        sleep(2);
    }

    echo "Done.";

    ob_end_flush();
?>

and its very important to keep de "4096" part because it seems that "fills" the buffer...

As we don't know what are the names of your activities classes, let's call your current activity Activity1, and the one you wish to open - Activity2 (these are the names of the classes)

First you need to define an intent that will be sent to Activity2:

Intent launchActivity2 = new Intent(Activity1.this, Activity2.class);

Then, you can simply launch the activity by running:
startActivity(launchActivity2 );

In VB.NET:

Dim webClient As New System.Net.WebClient
Dim result As String = webClient.DownloadString("http://api.hostip.info/?ip=68.180.206.184")

In C#:

System.Net.WebClient webClient = new System.Net.WebClient();
string result = webClient.DownloadString("http://api.hostip.info/?ip=68.180.206.184");

A two-liner which uses python. It works particularly well if you're writing a single .sh file and you don't want to depend on another .py file. It also leverages the usage of pipe |. echo "{\"field\": \"value\"}" can be replaced by anything printing a json to the stdout.

echo "{\"field\": \"value\"}" | python -c 'import sys, json
print(json.load(sys.stdin)["field"])'

Rather than querying the DOM for elements (which isn't very angular see "Thinking in AngularJS" if I have a jQuery background?) you should perform your DOM manipulation within your directive. The element is available to you in your link function.

So in your myDirective

return {
    link: function (scope, element, attr) {
        element.html('Hello world');
    }
}

If you must perform the query outside of the directive then it would be possible to use querySelectorAll in modern browers

angular.element(document.querySelectorAll("[my-directive]"));

however you would need to use jquery to support IE8 and backwards

angular.element($("[my-directive]"));

or write your own method as demonstrated here Get elements by attribute when querySelectorAll is not available without using libraries?

We can access super class elements by using super keyword

Consider we have two classes, Parent class and Child class, with different implementations of method foo. Now in child class if we want to call the method foo of parent class, we can do so by super.foo(); we can also access parent elements by super keyword.

    class parent {
    String str="I am parent";
    //method of parent Class
    public void foo() {
        System.out.println("Hello World " + str);
    }
}

class child extends parent {
    String str="I am child";
    // different foo implementation in child Class
    public void foo() {
        System.out.println("Hello World "+str);
    }

    // calling the foo method of parent class

Ubuntu Users:

I had the same problem and I fixed it by installing nodejson my system independent of the gem.

on ubuntu its: sudo apt-get install nodejs

I'm using 64bit ubuntu 11.10

update: From @Galina 's answer below I'm guessing that the latest version of nodejs is required, so @steve98177 your best option on a redhat(or CentOS) box is to install from source code as @Galina did, but as you can't "make/install" on this box ?, I suggest you try to install a fedora rpm(long shot) https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager or find another RH/CentOs box(that you can 'make' on) and create your own rpm and install on original RH box(if old glibc on RH plays nice).

The real issue here(IMHO) is installing Gems that have dependencies on installed packages outside of the ruby environment, is there a way of knowing before installing ? an RFI for Gems or bundler ?

CentOS/RedHat Users:

sudo yum install nodejs

If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:

• Bootstrap Datetime Picker 1

• Bootstrap Datetime Picker 2

The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.

Please check that your form tag have this attribute:

enctype="multipart/form-data"

Whether you're running within the context of ASP.NET or not, you should be able to use HostingEnvironment.ApplicationPhysicalPath

Hope this might be useful to you.

Write File:

private void writeToFile(String data,Context context) {
    try {
        OutputStreamWriter outputStreamWriter = new OutputStreamWriter(context.openFileOutput("config.txt", Context.MODE_PRIVATE));
        outputStreamWriter.write(data);
        outputStreamWriter.close();
    }
    catch (IOException e) {
        Log.e("Exception", "File write failed: " + e.toString());
    } 
}

Read File:

private String readFromFile(Context context) {

    String ret = "";

    try {
        InputStream inputStream = context.openFileInput("config.txt");

        if ( inputStream != null ) {
            InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
            BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
            String receiveString = "";
            StringBuilder stringBuilder = new StringBuilder();

            while ( (receiveString = bufferedReader.readLine()) != null ) {
                stringBuilder.append("\n").append(receiveString);
            }

            inputStream.close();
            ret = stringBuilder.toString();
        }
    }
    catch (FileNotFoundException e) {
        Log.e("login activity", "File not found: " + e.toString());
    } catch (IOException e) {
        Log.e("login activity", "Can not read file: " + e.toString());
    }

    return ret;
}

Below is the program to execute the rest api in python-

import requests
url = 'https://url'
data = '{  "platform": {    "login": {      "userName": "name",      "password": "pwd"    }  } }'
response = requests.post(url, data=data,headers={"Content-Type": "application/json"})
print(response)
sid=response.json()['platform']['login']['sessionId']   //to extract the detail from response
print(response.text)
print(sid)

Define the path of the Visual Studio in your ~/.bash_profile as follow

export PATH="$PATH:/Applications/Visual Studio Code.app/Contents/Resources/app/bin"

 public class Main extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        EditText et = (EditText) findViewById(R.id.et);
        EditText et_city = (EditText) findViewById(R.id.et_city);
        // Set the default text of second EditText widget
        et_city.setText("USA");
 }
}

The basic problem here is that you are mistaking System.Environment.Exit for return.

std::cout.precision(2);
std::cout<<std::fixed;

when you are using operator overloading try this.

Here is one way of getting the design that you want.

Start with the following HTML:

<div class="container">
    <div class="row-fluid">
        <div class="span12">
            <div class="nav">nav area</div>
            <div class="bg-image">
                <img src="http://unplugged.ee/wp-content/uploads/2013/03/frank2.jpg">
                 <h1>This is centered text.</h1>
            </div>
            <div class="main">main area</div>
        </div>
    </div>
</div>

Note that the background image is now part of the regular flow of the document.

Apply the following CSS:

.bg-image {
    position: relative;
}
.bg-image img {
    display: block;
    width: 100%;
    max-width: 1200px; /* corresponds to max height of 450px */
    margin: 0 auto;
}
.bg-image h1 {
    position: absolute;
    text-align: center;
    bottom: 0;
    left: 0;
    right: 0;
    color: white;
}
.nav, .main {
    background-color: #f6f6f6;
    text-align: center;
}

How This Works

The image is set an regular flow content with a width of 100%, so it will adjust itself responsively to the width of the parent container. However, you want the height to be no more than 450px, which corresponds to the image width of 1200px, so set the maximum width of the image to 1200px. You can keep the image centered by using display: block and margin: 0 auto.

The text is painted over the image by using absolute positioning. In the simplest case, I stretch the h1 element to be the full width of the parent and use text-align: center to center the text. Use the top or bottom offsets to place the text where it is needed.

If your banner images are going to vary in aspect ratio, you will need to adjust the maximum width value for .bg-image img dynamically using jQuery/Javascript, but otherwise, this approach has a lot to offer.

Below Bash Script Deletes all the tags located in registry except the latest.

for D in /registry-data/docker/registry/v2/repositories/*; do

    if [ -z "$(ls -A ${D}/_manifests/tags/)" ]; then
        echo ''
    else
        for R in $(ls -t ${D}/_manifests/tags/ | tail -n +2); do
            digest=$(curl -k -I -s -H -X GET http://xx.xx.xx.xx:5000/v2/$(basename  ${D})/manifests/${R} -H 'accept: application/vnd.docker.distribution.manifest.v2+json'  | grep Docker-Content-Digest | awk '{print $2}' )

Yes, every Android device have a unique serial numbers you can able to get it from this code. Build.SERIAL. Note that it was only added in API level 9, and it may not be present on all devices. To get a unique ID on earlier platforms, you'll need to read something like the MAC address or IMEI.

One can also make use of the tracemalloc module from the Python standard library. It seems to work well for objects whose class is implemented in C (unlike Pympler, for instance).

On macOS with the default python installation you need to add /Users/<you>/Library/Python/2.7/bin/ to your $PATH.

Add this to your .bash_profile:

export PATH="/Users/<you>/Library/Python/2.7/bin:$PATH"

That's where pip installs the executables.

Tip: For non-default python version which python to find the location of your python installation and replace that portion in the path above. (Thanks for the hint Sanket_Diwale)

For file and directory search purpose I would want to offer use specialized multithreading .NET library that possess a wide search opportunities and works very fast.

All information about library you can find on GitHub: https://github.com/VladPVS/FastSearchLibrary

If you want to download it you can do it here: https://github.com/VladPVS/FastSearchLibrary/releases

If you have any questions please ask them.

It is one demonstrative example how you can use it:

class Searcher
{
    private static object locker = new object(); 

    private FileSearcher searcher;

    List<FileInfo> files;

    public Searcher()
    {
        files = new List<FileInfo>(); // create list that will contain search result
    }

    public void Startsearch()
    {
        CancellationTokenSource tokenSource = new CancellationTokenSource();
        // create tokenSource to get stop search process possibility

        searcher = new FileSearcher(@"C:\", (f) =>
        {
            return Regex.IsMatch(f.Name, @".*[Dd]ragon.*.jpg$");
        }, tokenSource);  // give tokenSource in constructor


        searcher.FilesFound += (sender, arg) => // subscribe on FilesFound event
        {
            lock (locker) // using a lock is obligatorily
            {
                arg.Files.ForEach((f) =>
                {
                    files.Add(f); // add the next received file to the search results list
                    Console.WriteLine($"File location: {f.FullName}, \nCreation.Time: {f.CreationTime}");
                });

                if (files.Count >= 10) // one can choose any stopping condition
                    searcher.StopSearch();
            }
        };

        searcher.SearchCompleted += (sender, arg) => // subscribe on SearchCompleted event
        {
            if (arg.IsCanceled) // check whether StopSearch() called
                Console.WriteLine("Search stopped.");
            else
                Console.WriteLine("Search completed.");

            Console.WriteLine($"Quantity of files: {files.Count}"); // show amount of finding files
        };

        searcher.StartSearchAsync();
        // start search process as an asynchronous operation that doesn't block the called thread
    }
}

I had this and am mystified as to what has caused it, even after reading the above responses. My solution was to do

git reset --hard origin/master

Then that just resets my (local) copy of master (which I assume is screwed up) to the correct point, as represented by (remote) origin/master.

WARNING: You will lose all changes not yet pushed to origin/master.

The skinny is that a CPU loads data from memory addresses, stores data to memory addresses, and execute instructions sequentially out of memory addresses, with some conditional jumps in the sequence of instructions processed. Each of these three categories of instructions involves computing an address to a memory cell to be used in the machine instruction. Because machine instructions are of a variable length depending on the particular instruction involved, and because we string a variable length of them together as we build our machine code, there is a two step process involved in calculating and building any addresses.

First we laying out the allocation of memory as best we can before we can know what exactly goes in each cell. We figure out the bytes, or words, or whatever that form the instructions and literals and any data. We just start allocating memory and building the values that will create the program as we go, and note down anyplace we need to go back and fix an address. In that place we put a dummy to just pad the location so we can continue to calculate memory size. For example our first machine code might take one cell. The next machine code might take 3 cells, involving one machine code cell and two address cells. Now our address pointer is 4. We know what goes in the machine cell, which is the op code, but we have to wait to calculate what goes in the address cells till we know where that data will be located, i.e. what will be the machine address of that data.

If there were just one source file a compiler could theoretically produce fully executable machine code without a linker. In a two pass process it could calculate all of the actual addresses to all of the data cells referenced by any machine load or store instructions. And it could calculate all of the absolute addresses referenced by any absolute jump instructions. This is how simpler compilers, like the one in Forth work, with no linker.

A linker is something that allows blocks of code to be compiled separately. This can speed up the overall process of building code, and allows some flexibility with how the blocks are later used, in other words they can be relocated in memory, for example adding 1000 to every address to scoot the block up by 1000 address cells.

So what the compiler outputs is rough machine code that is not yet fully built, but is laid out so we know the size of everything, in other words so we can start to calculate where all of the absolute addresses will be located. the compiler also outputs a list of symbols which are name/address pairs. The symbols relate a memory offset in the machine code in the module with a name. The offset being the absolute distance to the memory location of the symbol in the module.

That's where we get to the linker. The linker first slaps all of these blocks of machine code together end to end and notes down where each one starts. Then it calculates the addresses to be fixed by adding together the relative offset within a module and the absolute position of the module in the bigger layout.

Obviously I've oversimplified this so you can try to grasp it, and I have deliberately not used the jargon of object files, symbol tables, etc. which to me is part of the confusion.

Try this:

public void test(){
// net.sf.json.JSONObject, net.sf.json.JSONArray    

List objList = new ArrayList();
objList.add("obj1");
objList.add("obj2");
objList.add("obj3");
HashMap objMap = new HashMap();
objMap.put("key1", "value1");
objMap.put("key2", "value2");
objMap.put("key3", "value3");
System.out.println("JSONArray :: "+(JSONArray)JSONSerializer.toJSON(objList));
System.out.println("JSONObject :: "+(JSONObject)JSONSerializer.toJSON(objMap));
}

you can find API here.

Before HTML5 we can use:

parent.location.hash = "hello";

and:

window.location.replace("http:www.example.com");

This method will reload your page, but HTML5 introduced the history.pushState(page, caption, replace_url) that should not reload your page.

Here's an example of how you'd use filter within your AngularJS JavaScript (rather than in an HTML element).

In this example, we have an array of Country records, each containing a name and a 3-character ISO code.

We want to write a function which will search through this list for a record which matches a specific 3-character code.

Here's how we'd do it without using filter:

$scope.FindCountryByCode = function (CountryCode) {
    //  Search through an array of Country records for one containing a particular 3-character country-code.
    //  Returns either a record, or NULL, if the country couldn't be found.
    for (var i = 0; i < $scope.CountryList.length; i++) {
        if ($scope.CountryList[i].IsoAlpha3 == CountryCode) {
            return $scope.CountryList[i];
        };
    };
    return null;
};

Yup, nothing wrong with that.

But here's how the same function would look, using filter:

$scope.FindCountryByCode = function (CountryCode) {
    //  Search through an array of Country records for one containing a particular 3-character country-code.
    //  Returns either a record, or NULL, if the country couldn't be found.

    var matches = $scope.CountryList.filter(function (el) { return el.IsoAlpha3 == CountryCode; })

    //  If 'filter' didn't find any matching records, its result will be an array of 0 records.
    if (matches.length == 0)
        return null;

    //  Otherwise, it should've found just one matching record
    return matches[0];
};

Much neater.

Remember that filter returns an array as a result (a list of matching records), so in this example, we'll either want to return 1 record, or NULL.

Hope this helps.

Objective-C

NSError *err = [NSError errorWithDomain:@"some_domain"
                                   code:100

                               }];

Swift 3

let error = NSError(domain: "some_domain",

                  userInfo: [NSLocalizedDescriptionKey: "Something went wrong"])

android_sdk_root is a system variable which points to root folder of android sdk tools. You probably get the error because the variable is not set. To set it in Android Studio go to:

1. File -> project Structure into Project Structure
2. Left -> SDK Location
3. SDK location select Android SDK location

If you have installed android SDK please refer to this answer to find the path to it: https://stackoverflow.com/a/15702396/3625900

I think Nosql is "more suitable" in these scenarios at least (more supplementary is welcome)

1. Easy to scale horizontally by just adding more nodes.

2. Query on large data set

   Imagine tons of tweets posted on twitter every day. In RDMS, there could be tables with millions (or billions?) of rows, and you don't want to do query on those tables directly, not even mentioning, most of time, table joins are also needed for complex queries.

3. Disk I/O bottleneck

   If a website needs to send results to different users based on users' real-time info, we are probably talking about tens or hundreds of thousands of SQL read/write requests per second. Then disk i/o will be a serious bottleneck.

string tail = test.Substring(test.LastIndexOf('-') + 1);

You can use a $ sign like:

OUTPUT=$(expression)

You may also want to try two backslashes (\\") to escape the escape character.

I've tried different cases and only when owner was set to nginx (chown -R nginx:nginx "/var/www/myfolder") - it started to work as expected.

With your example:

avgDists = np.array([1, 8, 6, 9, 4])

Obtain indexes of n maximal values:

ids = np.argpartition(avgDists, -n)[-n:]

Sort them in descending order:

ids = ids[np.argsort(avgDists[ids])[::-1]]

Obtain results (for n=4):

>>> avgDists[ids]
array([9, 8, 6, 4])

Seems the SMTP as internet standard uses only reliable Transport protocol. RFC821 has TCP, NCP, NITS as examples!

Add a word boundary \b at the end of the regex:

/^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}\b/

if the space after ) is optional:

/^(\([0-9]{3}\)\s*|[0-9]{3}-)[0-9]{3}-[0-9]{4}\b/

EDIT: This did/does work at the time I wrote it, but as Blexen pointed out, it's not in the spec.

Add an option like so:

<option default>Select Your Beverage</option>

The correct way:

<option selected="selected">Select Your Beverage</option>

HTTP 2.0 is a binary protocol that multiplexes numerous streams going over a single (normally TLS-encrypted) TCP connection.

The contents of each stream are HTTP 1.1 requests and responses, just encoded and packed up differently. HTTP2 adds a number of features to manage the streams, but leaves old semantics untouched.

Let me share my experience for this issue fix.

Open target -> Build phases -> Copy Bundle Resources and remove info.plist.

Note: If you're using any extensions, remove the info.plist of that extension from the Targets.

Hope it helps.

Because setting the div's display style property to "" doesn't change anything in the CSS rule itself. That basically just creates an "empty," inline CSS rule, which has no effect beyond clearing the same property on that element.

You need to set it to something that has a value:

document.getElementById('mybox').style.display = "block";

What you're doing would work if you were replacing an inline style on the div, like this:

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

document.getElementById('mybox').style.display = "";

You should bear in mind that a-z, A-Z, 0-9, ., _ and - are not the only valid characters in the start of an email address.

Gmail, for example, lets you put a "+" sign in the address to "fake" a different email (e.g. [email protected] will also get email sent to [email protected]).

micky.o'[email protected] would not appreciate your code stopping them entering their address ... apostrophes are perfectly valid in email addresses.

The Closure "check" of a valid email address mentioned above is, as it states itself, quite naïve:

http://code.google.com/p/closure-library/source/browse/trunk/closure/goog/format/emailaddress.js#198

I recommend being very open in your client side code, and then much more heavyweight like sending an email with a link to really check that it's "valid" (as in - syntactically valid for their provider, and also not misspelled).

Something like this:

var pattern = /[^@]+@[-a-z\.]\.[a-z\.]{2,6}/

Bearing in mind that theoretically you can have two @ signs in an email address, and I haven't even included characters beyond latin1 in the domain names!

The accepted answer is best, but since there's more than one way to do it, here's another solution:

if [ "$string" != "${string/foo/}" ]; then
    echo "It's there!"
fi

${var/search/replace} is $var with the first instance of search replaced by replace, if it is found (it doesn't change $var). If you try to replace foo by nothing, and the string has changed, then obviously foo was found.

I'm also open to suggestion on how to tidy this up, if there are any? :-)

Well, you could not use the span element, for semantic reasons. And you don't have to define the class PerformanceCell. The cells and rows can be accessed by using PerformanceTable tr {} and PerformanceTable tr {}, respectively.

For the spacing part, I have got the same problem several times. I shamefully admit I avoided the problem, so I am very curious to any answers too.

There are two ways you can do this; with patch and with patch.object

Patch assumes that you are not directly importing the object but that it is being used by the object you are testing as in the following

#foo.py
def some_fn():
    return 'some_fn'

class Foo(object):
    def method_1(self):
        return some_fn()

#bar.py
import foo
class Bar(object):
    def method_2(self):
        tmp = foo.Foo()
        return tmp.method_1()

#test_case_1.py
import bar
from mock import patch

@patch('foo.some_fn')
def test_bar(mock_some_fn):
    mock_some_fn.return_value = 'test-val-1'
    tmp = bar.Bar()
    assert tmp.method_2() == 'test-val-1'
    mock_some_fn.return_value = 'test-val-2'
    assert tmp.method_2() == 'test-val-2'

If you are directly importing the module to be tested, you can use patch.object as follows:

#test_case_2.py
import foo
from mock import patch

@patch.object(foo, 'some_fn')
def test_foo(test_some_fn):
    test_some_fn.return_value = 'test-val-1'
    tmp = foo.Foo()
    assert tmp.method_1() == 'test-val-1'
    test_some_fn.return_value = 'test-val-2'
    assert tmp.method_1() == 'test-val-2'

In both cases some_fn will be 'un-mocked' after the test function is complete.

Edit: In order to mock multiple functions, just add more decorators to the function and add arguments to take in the extra parameters

@patch.object(foo, 'some_fn')
@patch.object(foo, 'other_fn')
def test_foo(test_other_fn, test_some_fn):
    ...

Note that the closer the decorator is to the function definition, the earlier it is in the parameter list.

Event Modifiers

You can refer to event modifiers in vuejs to prevent form submission on enter key.

It is a very common need to call event.preventDefault() or event.stopPropagation() inside event handlers.

Although we can do this easily inside methods, it would be better if the methods can be purely about data logic rather than having to deal with DOM event details.

To address this problem, Vue provides event modifiers for v-on. Recall that modifiers are directive postfixes denoted by a dot.

<form v-on:submit.prevent="<method>">
  ...
</form>

As the documentation states, this is syntactical sugar for e.preventDefault() and will stop the unwanted form submission on press of enter key.

Here is a working fiddle.

new Vue({_x000D_
  el: '#myApp',_x000D_
  data: {_x000D_
    emailAddress: '',_x000D_
    log: ''_x000D_
  },_x000D_
  methods: {_x000D_
    validateEmailAddress: function(e) {_x000D_
      if (e.keyCode === 13) {_x000D_
        alert('Enter was pressed');_x000D_
      } else if (e.keyCode === 50) {_x000D_
        alert('@ was pressed');_x000D_
      }      _x000D_
      this.log += e.key;_x000D_
    },_x000D_
    _x000D_
    postEmailAddress: function() {_x000D_
   this.log += '\n\nPosting';_x000D_
    },_x000D_
    noop () {_x000D_
      // do nothing ?_x000D_
    }_x000D_
  }_x000D_
})

html, body, #editor {_x000D_
  margin: 0;_x000D_
  height: 100%;_x000D_
  color: #333;_x000D_
}

<script src="https://unpkg.com/[email protected]/dist/vue.js"></script>_x000D_
<div id="myApp" style="padding:2rem; background-color:#fff;">_x000D_
<form v-on:submit.prevent="noop">_x000D_
  <input type="text" v-model="emailAddress" v-on:keyup="validateEmailAddress" />_x000D_
  <button type="button" v-on:click="postEmailAddress" >Subscribe</button> _x000D_
  <br /><br />_x000D_
  _x000D_
  <textarea v-model="log" rows="4"></textarea>  _x000D_

</div>

FFMpeg can do this by seeking to the given timestamp and extracting exactly one frame as an image, see for instance:

ffmpeg -i input_file.mp4 -ss 01:23:45 -vframes 1 output.jpg

Let's explain the options:

-i input file           the path to the input file
-ss 01:23:45            seek the position to the specified timestamp
-vframes 1              only handle one video frame
output.jpg              output filename, should have a well-known extension

The -ss parameter accepts a value in the form HH:MM:SS[.xxx] or as a number in seconds. If you need a percentage, you need to compute the video duration beforehand.

Do you absolutely have to use clone? Most people agree that Java's clone is broken.

Josh Bloch on Design - Copy Constructor versus Cloning

If you've read the item about cloning in my book, especially if you read between the lines, you will know that I think clone is deeply broken. [...] It's a shame that Cloneable is broken, but it happens.

You may read more discussion on the topic in his book Effective Java 2nd Edition, Item 11: Override clone judiciously. He recommends instead to use a copy constructor or copy factory.

He went on to write pages of pages on how, if you feel you must, you should implement clone. But he closed with this:

Is all this complexities really necessary? Rarely. If you extend a class that implements Cloneable, you have little choice but to implement a well-behaved clone method. Otherwise, you are better off providing alternative means of object copying, or simply not providing the capability.

The emphasis was his, not mine.

Since you made it clear that you have little choice but to implement clone, here's what you can do in this case: make sure that MyObject extends java.lang.Object implements java.lang.Cloneable. If that's the case, then you can guarantee that you will NEVER catch a CloneNotSupportedException. Throwing AssertionError as some have suggested seems reasonable, but you can also add a comment that explains why the catch block will never be entered in this particular case.

Alternatively, as others have also suggested, you can perhaps implement clone without calling super.clone.

Swift 5:

1- Create a String extension to get attributedText

extension String {

    var underLined: NSAttributedString {
        NSMutableAttributedString(string: self, attributes: [.underlineStyle: NSUnderlineStyle.single.rawValue])
    }

}

2- Use it

On buttons:

button.setAttributedTitle(yourButtonTitle.underLined, for: .normal)

On Labels:

label.attributedText = yourLabelTitle.underLined

Or Stoyboard version

My solution would be after converting data to numerical type:

Top15[['Citable docs per Capita','Energy Supply per Capita']].corr()

put it your input field

ref={(el) => this.myInput = el}

You should override __repr__ or __unicode__ methods instead of using message, the args you provide when you construct the exception will be in the args attribute of the exception object.

glOrtho describes a transformation that produces a parallel projection. The current matrix (see glMatrixMode) is multiplied by this matrix and the result replaces the current matrix, as if glMultMatrix were called with the following matrix as its argument:

OpenGL documentation (my bold)

The numbers define the locations of the clipping planes (left, right, bottom, top, near and far).

The "normal" projection is a perspective projection that provides the illusion of depth. Wikipedia defines a parallel projection as:

Parallel projections have lines of projection that are parallel both in reality and in the projection plane.

Parallel projection corresponds to a perspective projection with a hypothetical viewpoint—e.g., one where the camera lies an infinite distance away from the object and has an infinite focal length, or "zoom".

If you just want a number to come back try this.

create temp sequence temp_seq;
SELECT inline_v1.ROWNUM,inline_v1.c1
FROM
(
select nextval('temp_seq') as ROWNUM, c1 
from sometable
)inline_v1;

You can add a order by to the inline_v1 SQL so your ROWNUM has some sequential meaning to your data.

select nextval('temp_seq') as ROWNUM, c1 
from sometable
ORDER BY c1 desc;

Might not be the fastest, but it's an option if you really do need them.

This action is not bound to a key by default, to bind it do this:

1. File > Preferences > Keyboard Shortcuts (Ctrl+K, Ctrl+S)
2. Search for "find folder"
3. Press the + icon on the left of "filesExplorer.findInFolder" search result
4. Enter your desired key combination

On Linux, give read/write permissions to the entire folder containing the database file.

Also, SELinux might be blocking the write. You need to set the correct permissions.

In my SELinux Management GUI (on Fedora 19), I checked the box on the line labelled httpd_unified (Unify HTTPD handling of all content files), and I was good to go.

>> items = [1,2,3,4]
>> Z = [3,4,5,6]

>> print list(set(items)-set(Z))
[1, 2]

I faced the same 415 http error when sending objects, serialized into JSON, via PUT/PUSH requests to my JAX-rs services, in other words my server was not able to de-serialize the objects from JSON. In my case, the server was able to serialize successfully the same objects in JSON when sending them into its responses.

As mentioned in the other responses I have correctly set the Accept and Content-Type headers to application/json, but it doesn't suffice.

Solution

I simply forgot a default constructor with no parameters for my DTO objects. Yes this is the same reasoning behind @Entity objects, you need a constructor with no parameters for the ORM to instantiate objects and populate the fields later.

Adding the constructor with no parameters to my DTO objects solved my issue. Here follows an example that resembles my code:

Wrong

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {
    public NumberDTO(Number number) {
        this.number = number;
    }

    private Number number;

    public Number getNumber() {
        return number;
    }

    public void setNumber(Number string) {
        this.number = string;
    }
}

Right

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {

    public NumberDTO() {
    }

    public NumberDTO(Number number) {
        this.number = number;
    }

    private Number number;

    public Number getNumber() {
        return number;
    }

    public void setNumber(Number string) {
        this.number = string;
    }
}

I lost hours, I hope this'll save yours ;-)

You cannot do it with just method, unless you use some javascript framework like jquery which supports it ..

string s = '<div id="myDiv"></div>'
var htmlObject = $(s); // jquery call

but still, it would not be found by the getElementById because for that to work the element must be in the DOM... just creating in the memory does not insert it in the dom.

You would need to use append or appendTo or after etc.. to put it in the dom first..

Of'course all these can be done through regular javascript but it would take more steps to accomplish the same thing... and the logic is the same in both cases..

you can do this---

<input type="button" onClic="changebackColor">

function changebackColor(){
document.body.style.backgroundColor = "black";
document.getElementByID("divID").style.backgroundColor = "black";      
window.setTimeout("yourFunction()",10000);
}

Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%" - but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.

It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.

To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%".

Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.

Updated answer to reflect question update:

I say that doing a WHERE field LIKE "%value%" is slower than WHERE field LIKE "value%" if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:

1/ If you do SELECT field FROM table WHERE field LIKE "%value%", MySQL will scan the entire table, and only send the fields containing "value".

2/ If you do SELECT field FROM table and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.

Solution: Please do use the WHERE clause, and use EXPLAIN to see the performance.
