Here is all you need to know about relative file paths:

• Starting with / returns to the root directory and starts there

• Starting with ../ moves one directory backward and starts there

• Starting with ../../ moves two directories backward and starts there (and so on...)

• To move forward, just start with the first sub directory and keep moving forward.

Since there's no language listed, I'll answer this in Swift. We highly recommend using Firebase Storage and the Firebase Realtime Database together to accomplish lists of downloads:

Shared:

// Firebase services
var database: FIRDatabase!
var storage: FIRStorage!
...
// Initialize Database, Auth, Storage
database = FIRDatabase.database()
storage = FIRStorage.storage()
...
// Initialize an array for your pictures
var picArray: [UIImage]()

Upload:

let fileData = NSData() // get data...
let storageRef = storage.reference().child("myFiles/myFile")
storageRef.putData(fileData).observeStatus(.Success) { (snapshot) in
  // When the image has successfully uploaded, we get it's download URL
  let downloadURL = snapshot.metadata?.downloadURL()?.absoluteString
  // Write the download URL to the Realtime Database
  let dbRef = database.reference().child("myFiles/myFile")
  dbRef.setValue(downloadURL)
}

Download:

let dbRef = database.reference().child("myFiles")
dbRef.observeEventType(.ChildAdded, withBlock: { (snapshot) in
  // Get download URL from snapshot
  let downloadURL = snapshot.value() as! String
  // Create a storage reference from the URL
  let storageRef = storage.referenceFromURL(downloadURL)
  // Download the data, assuming a max size of 1MB (you can change this as necessary)
  storageRef.dataWithMaxSize(1 * 1024 * 1024) { (data, error) -> Void in
    // Create a UIImage, add it to the array
    let pic = UIImage(data: data)
    picArray.append(pic)
  })
})

For more information, see Zero to App: Develop with Firebase, and it's associated source code, for a practical example of how to do this.

Other alternatives for summing the columns are

numpy.einsum('ij->j', a)

and

numpy.dot(a.T, numpy.ones(a.shape[0]))

If the number of rows and columns is in the same order of magnitude, all of the possibilities are roughly equally fast:

If there are only a few columns, however, both the einsum and the dot solution significantly outperform numpy's sum (note the log-scale):

Code to reproduce the plots:

import numpy
import perfplot


def numpy_sum(a):
    return numpy.sum(a, axis=1)


def einsum(a):
    return numpy.einsum('ij->i', a)


def dot_ones(a):
    return numpy.dot(a, numpy.ones(a.shape[1]))


perfplot.save(
    "out1.png",
    # setup=lambda n: numpy.random.rand(n, n),
    setup=lambda n: numpy.random.rand(n, 3),
    n_range=[2**k for k in range(15)],
    kernels=[numpy_sum, einsum, dot_ones],
    logx=True,
    logy=True,
    xlabel='len(a)',
    )

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

TS has a JavaScript runtime

Typescript has a JavaScript runtime because it gets compiled to JS. This means JS objects which are built in as part of the language such as JSON, Object, and Math are also available in TS. Therefore we can just use the JSON.parse method to parse the JSON string.

Example:

const JSONStr = '{"name": "Bob", "error": false}'

// The JSON object is part of the runtime
const parsedObj = JSON.parse(JSONStr);

console.log(parsedObj);
// [LOG]: {
//   "name": "Bob",
//   "error": false
// } 

// The Object object is also part of the runtime so we can use it in TS
const objKeys = Object.keys(parsedObj);

console.log(objKeys);
// [LOG]: ["name", "error"] 

The only thing now is that parsedObj is type any which is generally a bad practice in TS. We can type the object if we are using type guards. Here is an example:

const JSONStr = '{"name": "Bob", "error": false}'
const parsedObj = JSON.parse(JSONStr);

interface nameErr {
  name: string;
  error: boolean;
}

function isNameErr(arg: any): arg is nameErr {
  if (typeof arg.name === 'string' && typeof arg.error === 'boolean') {
    return true;
  } else {
    return false;
  }
}

if (isNameErr(parsedObj)) {
  // Within this if statement parsedObj is type nameErr;
  parsedObj
}

There is Array.filter():

var numbers = [1, 2, 3, 4, 5];
var filtered = numbers.filter(function(x) { return x > 3; });

// As a JavaScript 1.8 expression closure
filtered = numbers.filter(function(x) x > 3);

Note that Array.filter() is not standard ECMAScript, and it does not appear in ECMAScript specs older than ES5 (thanks Yi Jiang and jAndy). As such, it may not be supported by other ECMAScript dialects like JScript (on MSIE).

Nov 2020 Update: Array.filter is now supported across all major browsers.

I'm getting an index out of range error with the accepted answer solution. Reason: When range start, it is not iterate value one by one, it is iterate by index. If you modified a slice while it is in range, it will induce some problem.

Old Answer:

chars := []string{"a", "a", "b"}

for i, v := range chars {
    fmt.Printf("%+v, %d, %s\n", chars, i, v)
    if v == "a" {
        chars = append(chars[:i], chars[i+1:]...)
    }
}
fmt.Printf("%+v", chars)

Expected :

[a a b], 0, a
[a b], 0, a
[b], 0, b
Result: [b]

Actual:

// Autual
[a a b], 0, a
[a b], 1, b
[a b], 2, b
Result: [a b]

Correct Way (Solution):

chars := []string{"a", "a", "b"}

for i := 0; i < len(chars); i++ {
    if chars[i] == "a" {
        chars = append(chars[:i], chars[i+1:]...)
        i-- // form the remove item index to start iterate next item
    }
}

fmt.Printf("%+v", chars)

The Denver SQL Server Users group has had some really good presentations over the last couple of months on the new features in SQL 2008 including one from Paul Nielsen just last week shortly after he got back from "Jump Start" up in Redmond (if I remember the name of the event correctly).

A couple of caveats on all of the "new features" for SQL 2008, the triage to determine which features will be in the various editions is still in progress. Many/most of the new/very cool features like data compression, partitioned indexes, policies, etc. are only going to be in the enterprise edition. Unless you're planning on running enterprise edition a lot of the features that are in the CTP's will probably not be in SQL 2008 standard, etc.

On other minor but often overlooked issue - SQL 2008 will only be 64-bit, if you're buying new hardware shouldn't be an issue but if you're planning on using existing hardware... also, if you've got dependencies on third party drivers (e.g. oracle) best be sure that a 64-bit version is available/works

you need to use -e flag for echo then you can

echo -e "\t\t x"

Sure, a Linked List is a bit confusing for programming n00bs, pretty much the temptation is to look at it as Russian Dolls, because that's what it seems like, a LinkedList Object in a LinkedList Object. But that's a touch difficult to visualize, instead look at it like a computer.

LinkedList = Data + Next Member

Where it's the last member of the list if next is NULL

So a 5 member LinkedList would be:

LinkedList(Data1, LinkedList(Data2, LinkedList(Data3, LinkedList(Data4, LinkedList(Data5, NULL)))))

But you can think of it as simply:

Data1 -> Data2 -> Data3 -> Data4 -> Data5 -> NULL

So, how do we find the end of this? Well, we know that the NULL is the end so:

public void append(LinkedList myNextNode) {
  LinkedList current = this; //Make a variable to store a pointer to this LinkedList
  while (current.next != NULL) { //While we're not at the last node of the LinkedList
    current = current.next; //Go further down the rabbit hole.
  }
  current.next = myNextNode; //Now we're at the end, so simply replace the NULL with another Linked List!
  return; //and we're done!
}

This is very simple code of course, and it will infinitely loop if you feed it a circularly linked list! But that's the basics.

Here is a way to do this with the Walrus Operator (new in Python 3.8)

f = open("a.txt", "r")

while (c := f.read(n)):
    process(c)

f.close()

Useful Python Docs (3.8):

Another option that worked for me was to bind the network namespace of the host to the docker.

By adding:

docker run --net host

Using table-layout: fixed as a property for table and width: calc(100%/3); for td (assuming there are 3 td's). With these two properties set, the table cells will be equal in size.

Refer to the demo.

No loop necessary. Three methods that come to mind:

Array.prototype.some()

This is the most exact answer for your question, i.e. "check if something exists", implying a bool result. This will be true if there are any 'Magenic' objects, false otherwise:

let hasMagenicVendor = vendors.some( vendor => vendor['Name'] === 'Magenic' )

Array.prototype.filter()

This will return an array of all 'Magenic' objects, even if there is only one (will return a one-element array):

let magenicVendors = vendors.filter( vendor => vendor['Name'] === 'Magenic' )

If you try to coerce this to a boolean, it will not work, as an empty array (no 'Magenic' objects) is still truthy. So just use magenicVendors.length in your conditional.

Array.prototype.find()

This will return the first 'Magenic' object (or undefined if there aren't any):

let magenicVendor = vendors.find( vendor => vendor['Name'] === 'Magenic' );

This coerces to a boolean okay (any object is truthy, undefined is falsy).

Note: I'm using vendor["Name"] instead of vendor.Name because of the weird casing of the property names.

Note 2: No reason to use loose equality (==) instead of strict equality (===) when checking the name.

This is what you would like to do:

OurKey.SetValue("Password", StringEncryptor.EncryptString(textBoxPassword.Text));
OurKey.GetValue("Password", StringEncryptor.DecryptString(textBoxPassword.Text));

You can do that with this the following classes. This class is a generic class is the client endpoint. It enables IOC of various encryption algorithms using Ninject.

public class StringEncryptor
{
    private static IKernel _kernel;

    static StringEncryptor()
    {
        _kernel = new StandardKernel(new EncryptionModule());
    }

    public static string EncryptString(string plainText)
    {
        return _kernel.Get<IStringEncryptor>().EncryptString(plainText);
    }

    public static string DecryptString(string encryptedText)
    {
        return _kernel.Get<IStringEncryptor>().DecryptString(encryptedText);
    }
}

This next class is the ninject class that allows you to inject the various algorithms:

public class EncryptionModule : StandardModule
{
    public override void Load()
    {
        Bind<IStringEncryptor>().To<TripleDESStringEncryptor>();
    }
}

This is the interface that any algorithm needs to implement to encrypt/decrypt strings:

public interface IStringEncryptor
{
    string EncryptString(string plainText);
    string DecryptString(string encryptedText);
}

This is a implementation using the TripleDES algorithm:

public class TripleDESStringEncryptor : IStringEncryptor
{
    private byte[] _key;
    private byte[] _iv;
    private TripleDESCryptoServiceProvider _provider;

    public TripleDESStringEncryptor()
    {
        _key = System.Text.ASCIIEncoding.ASCII.GetBytes("GSYAHAGCBDUUADIADKOPAAAW");
        _iv = System.Text.ASCIIEncoding.ASCII.GetBytes("USAZBGAW");
        _provider = new TripleDESCryptoServiceProvider();
    }

    #region IStringEncryptor Members

    public string EncryptString(string plainText)
    {
        return Transform(plainText, _provider.CreateEncryptor(_key, _iv));
    }

    public string DecryptString(string encryptedText)
    {
        return Transform(encryptedText, _provider.CreateDecryptor(_key, _iv));
    }

    #endregion

    private string Transform(string text, ICryptoTransform transform)
    {
        if (text == null)
        {
            return null;
        }
        using (MemoryStream stream = new MemoryStream())
        {
            using (CryptoStream cryptoStream = new CryptoStream(stream, transform, CryptoStreamMode.Write))
            {
                byte[] input = Encoding.Default.GetBytes(text);
                cryptoStream.Write(input, 0, input.Length);
                cryptoStream.FlushFinalBlock();

                return Encoding.Default.GetString(stream.ToArray());
            }
        }
    }
}

Underscore-java library contains methods push(values), pop(), shift() and unshift(values).

Code example:

import com.github.underscore.U:

List<String> strings = Arrays.asList("one", "two", " three");
List<String> newStrings = U.push(strings, "four", "five");
// ["one", " two", "three", " four", "five"]
String newPopString = U.pop(strings).fst();
// " three"
String newShiftString = U.shift(strings).fst();
// "one"
List<String> newUnshiftStrings = U.unshift(strings, "four", "five");
// ["four", " five", "one", " two", "three"]

Note: There is no magic to animating a gif: it is either an animated gif or it is not. If the gif is not visible, very likely the path to the gif is wrong - or, as in your case, the container (div/p/etc) is not large enough to display it. In your code sample, you did not specify height or width and that appeared to be problem.

If the gif is displayed but not animating, see reference links at very bottom of this answer.

Displaying the gif + overlay, however, is easier than you might think.

All you need are two absolute-position DIVs: an overlay div, and a div that contains your loading gif. Both have higher z-index than your page content, and the image has a higher z-index than the overlay - so they will display above the page when visible.

So, when the button is pressed, just unhide those two divs. That's it!

Once upon a midnight dreary, while I pondered weak and weary, over many a quaint and curious routine of forgotten code... While I nodded, nearly napping, suddenly there came a tapping... as of someone gently rapping - rapping at my office door. 'Tis the team leader, I muttered, tapping at my office door - only this and nothing more. Ah, distinctly I remember it was in the bleak December and each separate React print-out lay there crumpled on the floor. Eagerly I wished the morrow; vainly I had sought to borrow from Stack-O surcease from sorrow - sorrow for my routine's core. For the brilliant but unworking code my angels seem to just ignore. I'll be tweaking code... forevermore! - <a href="http://www.online-literature.com/poe/335/" target="_blank">Apologies To Poe</a></div>_x000D_

Continuing this answer, There is another difference that if you want your method to return different values for example when it is first time called, second time called etc then you can pass values so for example...

PowerMockito.doReturn(false, false, true).when(SomeClass.class, "SomeMethod", Matchers.any(SomeClass.class));

So it will return false when the method is called in same test case and then it will return false again and lastly true.

Another option would be to use a symbolic link. ie:

ln -s ~/Files/Scripts/Main ~/myFold

After that you can perform operations to ~/myFold, such as:

cp some_file.txt ~/myFold

which will put the file in ~/Files/Scripts/Main. You can remove the symbolic link at any time with rm ~/myFold, which will keep the original directory.

Here some guide how to fix it. Go to :

cd /var/www

sudo chown www-data:www-data * -R

sudo usermod -a -G www-data username

Change userneme with your username. I hope it help.

BalusC excellent answer covers most of the patterns for web applications.

Some application may require Chain-of-responsibility_pattern

In object-oriented design, the chain-of-responsibility pattern is a design pattern consisting of a source of command objects and a series of processing objects. Each processing object contains logic that defines the types of command objects that it can handle; the rest are passed to the next processing object in the chain.

Use case to use this pattern:

When handler to process a request(command) is unknown and this request can be sent to multiple objects. Generally you set successor to object. If current object can't handle the request or process the request partially and forward the same request to successor object.

Useful SE questions/articles:

Why would I ever use a Chain of Responsibility over a Decorator?

Non-regex solution

I ran some benchmarks, and this solution won hugely:¹

str.slice(str.indexOf(delim) + delim.length)

// as function
function gobbleStart(str, delim) {
    return str.slice(str.indexOf(delim) + delim.length);
}

// as polyfill
String.prototype.gobbleStart = function(delim) {
    return this.slice(this.indexOf(delim) + delim.length);
};

Performance comparison with other solutions

The only close contender was the same line of code, except using substr instead of slice.

Other solutions I tried involving split or RegExps took a big performance hit and were about 2 orders of magnitude slower. Using join on the results of split, of course, adds an additional performance penalty.

Why are they slower? Any time a new object or array has to be created, JS has to request a chunk of memory from the OS. This process is very slow.

Here are some general guidelines, in case you are chasing benchmarks:

• New dynamic memory allocations for objects {} or arrays [] (like the one that split creates) will cost a lot in performance.
• RegExp searches are more complicated and therefore slower than string searches.
• If you already have an array, destructuring arrays is about as fast as explicitly indexing them, and looks awesome.

Removing beyond the first instance

Here's a solution that will slice up to and including the nth instance. It's not quite as fast, but on the OP's question, gobble(element, '_', 1) is still >2x faster than a RegExp or split solution and can do more:

/*
`gobble`, given a positive, non-zero `limit`, deletes
characters from the beginning of `haystack` until `needle` has
been encountered and deleted `limit` times or no more instances
of `needle` exist; then it returns what remains. If `limit` is
zero or negative, delete from the beginning only until `-(limit)`
occurrences or less of `needle` remain.
*/
function gobble(haystack, needle, limit = 0) {
  let remain = limit;
  if (limit <= 0) { // set remain to count of delim - num to leave
    let i = 0;
    while (i < haystack.length) {
      const found = haystack.indexOf(needle, i);
      if (found === -1) {
        break;
      }
      remain++;
      i = found + needle.length;
    }
  }

  let i = 0;
  while (remain > 0) {
    const found = haystack.indexOf(needle, i);
    if (found === -1) {
      break;
    }
    remain--;
    i = found + needle.length;
  }
  return haystack.slice(i);
}

With the above definition, gobble('path/to/file.txt', '/') would give the name of the file, and gobble('prefix_category_item', '_', 1) would remove the prefix like the first solution in this answer.

1. Tests were run in Chrome 70.0.3538.110 on macOSX 10.14.

In the following example you have an PHP array, then firstly create a JavaScript array by a PHP array:

<script type="javascript">
    day = new Array(<?php echo implode(',', $day); ?>);
    week = new Array(<?php echo implode(',',$week); ?>);
    month = new Array(<?php echo implode(',',$month); ?>);

    <!--  Then pass it to the JavaScript function:   -->

    drawChart(<?php echo count($day); ?>, day, week, month);
</script>

$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential("username", "password");
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body)

Just change $EmailTo, and username/password in $SMTPClient.Credentials... Do not include @gmail.com in your username...

On some OS you get . .. and .DS_Store, Well we can't use them so let's us hide them.

First start get all information about the files, using scandir()

// Folder where you want to get all files names from
$dir = "uploads/";

/* Hide this */
$hideName = array('.','..','.DS_Store');    

// Sort in ascending order - this is default
$files = scandir($dir);
/* While this to there no more files are */
foreach($files as $filename) {
    if(!in_array($filename, $hideName)){
       /* echo the name of the files */
       echo "$filename<br>";
    }
}

There are two reasons you might get this message:

1. ASP.Net is not configured. For this run from Administrator command %FrameworkDir%\%FrameworkVersion%\aspnet_regiis -i. Read the message carefully. On Windows8/IIS8 it may say that this is no longer supported and you may have to use Turn Windows Features On/Off dialog in Install/Uninstall a Program in Control Panel.
2. Another reason this may happen is because your App Pool is not configured correctly. For example, you created website for WordPress and you also want to throw in few aspx files in there, WordPress creates app pool that says don't run CLR stuff. To fix this just open up App Pool and enable CLR.

You can use SimpleDateformat for change string to date

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String strDate = "2000-01-01";
Date date = sdf.parse(strDate);

Here is what worked for me (Angular 7):

First import HttpClientModule in your app.module.ts if you didn't:

import { HttpClientModule } from '@angular/common/http';
...
imports: [
        HttpClientModule
    ],

Then change your service

@Injectable()
export class FooService {

to

@Injectable({
    providedIn: 'root'
})
export class FooService {

Hope it helps.

Edit:

providedIn

Determines which injectors will provide the injectable, by either associating it with an @NgModule or other InjectorType, or by specifying that this injectable should be provided in one of the following injectors:

'root' : The application-level injector in most apps.

'platform' : A special singleton platform injector shared by all applications on the page.

'any' : Provides a unique instance in every module (including lazy modules) that injects the token.

Be careful platform is available only since Angular 9 (https://blog.angular.io/version-9-of-angular-now-available-project-ivy-has-arrived-23c97b63cfa3)

Read more about Injectable here: https://angular.io/api/core/Injectable

Looking around for an API Level 5 solution using ContactsContract API you could slightly modify the code above with the following:

  Intent intent = new Intent(Intent.ACTION_PICK);
  intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
  startActivityForResult(intent, PICK_CONTACT);

And then in onActivityResult use the column name:

  ContactsContract.Contacts.DISPLAY_NAME

It is not possible to get the users computer name with Javascript. You can get all details about the browser and network. But not more than that.

Like some one answered in one of the previous question today.

I already did a favor of visiting your website, May be I will return or refer other friends.. I also told you where I am and what OS, Browser and screen resolution I use Why do you want to know the color of my underwear? ;-)

You cannot do it using asp.net as well.

In Select2 version 4 each option has the same properties of the objects in the list;

if you have the object

Obj = {
  name: "Alberas",
  description: "developer",
  birthDate: "01/01/1990"
}

then you retrieve the selected data

var data = $('#id-selected-input').select2('data');
console.log(data[0].name);
console.log(data[0].description);
console.log(data[0].birthDate);
 

If you are using localhost and PHP set to this to solve the issue:

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: Content-Type'); 

From your front-end use:

{headers: {"Content-Type": "application/json"}}

and boom no more issues from localhost!

Just had same problem. Using Xcode 8.3.3 and wanted to use AppIcon in Assests catalogue. Tried all sorts of Stack Overflow answers without success.

Finally learned about a deep clean step from Ken/Apple Forum:

• removed all icon files, whether from resources (delete - trash) or appicon file (select - remove selected items); removed even assets folder
• deep cleaned (Use the Product menu w/option key pressed, then choose to 'clean build folder')

• added a new asset catalogue and called it "Assets" right clicked in Assets folder and added new app icon set - changed that one in inspector to be for iOS >=7 triple

• checked all my icon files OUTSIDE of Xcode (all were already png files of right resolution, but some had still colour profile attached from photoshop elements or did have indexed colour instead of RGB profile. so I made sure I only save a png file without colour profile and from a background layer) - not sure that was necessary

• archived the build from Product menu
• validated and uploaded the build from Window - Organizer

Or simple Sass-Compass:

@mixin col-xs() {
    @media (max-width: 767px) {
        @content;
    }
}
@mixin col-sm() {
    @media (min-width: 768px) and (max-width: 991px) {
        @content;
    }
}
@mixin col-md() {
    @media (min-width: 992px) and (max-width: 1199px) {
        @content;
    }
}
@mixin col-lg() {
    @media (min-width: 1200px) {
        @content;
    }
}

Example:

#content-box {
    @include border-radius(18px);
    @include adjust-font-size-to(18pt);
    padding:20px;
    border:1px solid red;
    @include col-xs() {
        width: 200px;
        float: none;
    }
}

Say you want to save the string I'm a "foobar" in the database.
Your query will look something like INSERT INTO foos (text) VALUES ("$text").
With the $text variable replaced, this will look like this:

INSERT INTO foos (text) VALUES ("I'm a "foobar"")

Now, where exactly does the string end? You may know, an SQL parser doesn't. Not only will this simply break this query, it can also be abused to inject SQL commands you didn't intend.

mysql_real_escape_string makes sure such ambiguities do not occur by escaping characters which have special meaning to an SQL parser:

mysql_real_escape_string($text)  =>  I\'m a \"foobar\"

This becomes:

INSERT INTO foos (text) VALUES ("I\'m a \"foobar\"")

This makes the statement unambiguous and safe. The \ signals that the following character is not to be taken by its special meaning as string terminator. There are a few such characters that mysql_real_escape_string takes care of.

Escaping is a pretty universal thing in programming languages BTW, all along the same lines. If you want to type the above sentence literally in PHP, you need to escape it as well for the same reasons:

$text = 'I\'m a "foobar"';
// or
$text = "I'm a \"foobar\"";

Anchor href link apply to li:

#menu li a {
       display:block;
    }

HTML:

<select onchange="cityChanged(this.value)">
      <option value="CHICAGO">Chicago</option>
      <option value="NEWYORK">New York</option>
</select>

JS:

function cityChanged(city) {
    alert(city);
}

To do this cross browser including IE7+, you will need to expand the plugin with a transformation matrix. Since vendor prefix is done in jQuery from jquery-1.8+ I will leave that out for the transform property.

$.fn.animateRotate = function(endAngle, options, startAngle)
{
    return this.each(function()
    {
        var elem = $(this), rad, costheta, sintheta, matrixValues, noTransform = !('transform' in this.style || 'webkitTransform' in this.style || 'msTransform' in this.style || 'mozTransform' in this.style || 'oTransform' in this.style),
            anims = {}, animsEnd = {};
        if(typeof options !== 'object')
        {
            options = {};
        }
        else if(typeof options.extra === 'object')
        {
            anims = options.extra;
            animsEnd = options.extra;
        }
        anims.deg = startAngle;
        animsEnd.deg = endAngle;
        options.step = function(now, fx)
        {
            if(fx.prop === 'deg')
            {
                if(noTransform)
                {
                    rad = now * (Math.PI * 2 / 360);
                    costheta = Math.cos(rad);
                    sintheta = Math.sin(rad);
                    matrixValues = 'M11=' + costheta + ', M12=-'+ sintheta +', M21='+ sintheta +', M22='+ costheta;
                    $('body').append('Test ' + matrixValues + '<br />');
                    elem.css({
                        'filter': 'progid:DXImageTransform.Microsoft.Matrix(sizingMethod=\'auto expand\','+matrixValues+')',
                        '-ms-filter': 'progid:DXImageTransform.Microsoft.Matrix(sizingMethod=\'auto expand\','+matrixValues+')'
                    });
                }
                else
                {
                    elem.css({
                        //webkitTransform: 'rotate('+now+'deg)',
                        //mozTransform: 'rotate('+now+'deg)',
                        //msTransform: 'rotate('+now+'deg)',
                        //oTransform: 'rotate('+now+'deg)',
                        transform: 'rotate('+now+'deg)'
                    });
                }
            }
        };
        if(startAngle)
        {
            $(anims).animate(animsEnd, options);
        }
        else
        {
            elem.animate(animsEnd, options);
        }
    });
};

Note: The parameters options and startAngle are optional, if you only need to set startAngle use {} or null for options.

Example usage:

var obj = $(document.createElement('div'));
obj.on("click", function(){
    obj.stop().animateRotate(180, {
        duration: 250,
        complete: function()
        {
            obj.animateRotate(0, {
                duration: 250
            });
        }
    });
});
obj.text('Click me!');
obj.css({cursor: 'pointer', position: 'absolute'});
$('body').append(obj);

See also this jsfiddle for a demo.

Update: You can now also pass extra: {} in the options. This will make you able to execute other animations simultaneously. For example:

obj.animateRotate(90, {extra: {marginLeft: '100px', opacity: 0.5}});

This will rotate the element 90 degrees, and move it to the right with 100px and make it semi-transparent all at the same time during the animation.

Run

rake db:migrate:down VERSION=<version>

Where <version> is the version number of your migration file you want to revert.

Example:-

rake db:migrate:down VERSION=3846656238

re.sub is definitely what you are looking for. And so you know, you don't need the anchors and the wildcards.

re.sub(r"(?i)interfaceOpDataFile", "interfaceOpDataFile %s" % filein, line)

will do the same thing--matching the first substring that looks like "interfaceOpDataFile" and replacing it.

Never ever mix more languages.

<script type="text/javascript">
    var data = @Json.Encode(Model); // !!!! export data !!!!

    for(var prop in data){
      console.log( prop + " "+ data[prop]);
    }

In case of problem you can also try

@Html.Raw(Json.Encode(Model));

To create icon you can use Glyphicon in Bootstrap:

<a href="#" class="btn btn-info btn-sm">
    <span class="glyphicon glyphicon-menu-hamburger"></span>
</a>

And then control size of icon in css:

.glyphicon-menu-hamburger {
  font-size: npx;
}

Simplest solution:

Just add quotes, I really don't know why it's not auto-implemented by Spring boot when response type defined as application/json, but it works great.

@PostMapping("/create")
public String foo()
{
    String result = "something"
    return "\"" + result + "\"";
}

I tried to put the font size in the styles.xml but when i went to use it it was only allowing resources from the dimen folder so put it in there instead, dont know it this is right

        <Button
                android:layout_weight="1"
                android:id="@+id/three_btn"
                android:layout_height="match_parent"
                android:layout_width="0dp"
                android:onClick="onButtonClick"
                android:textColor="#EEEEEE"
                android:textStyle="bold"
                android:textSize="@dimen/buttonFontSize"
                android:text="3"/>

Please try something like:

=IF(LEN(C1)>10,VALUE(LEFT(C1,FIND(" ",C1,8))),IF(ISTEXT(C1),DATE(RIGHT(C1,4),MID(C1,4,2),LEFT(C1,2)),C1))  

You seem to have three main possible scenarios:

1. Space-separated date with time as text (eg as A1 below)
2. Hyphen-separated date as text (eg as A2 below)
3. Formatted date index (as A4 and A5 below)

ColumnA below is formatted General and ColumnB as Date (my default setting). ColumnC also as date but with custom formatting to suit the appearances mentioned in your question.
A clue as to whether or not text format is the left or right alignment of the cells’ contents.

I am suggesting separate treatment for each of the above three main cases, so use =IF to differentiate them.

Case #1

This is longer than any of the others, so can be distinguished as having a length greater than say 10 characters, with =LEN.
In this case we want all but the last six characters but for added flexibility (for instance, in case the time element included seconds) I have chosen to count from the left rather than from the right. The problem then is that the month names may vary in length, so I have chosen to look for the space that immediately follows the year to indicate the limit for the relevant number of characters.

This with =FIND which looks for a space (" ") in C1, starting with the eighth character within C1 counting from the left, on the assumption that for this case days will be expressed as two characters and months as three or more.

Since =LEFT is a string function it returns a string, but this can be converted to a value with=VALUE.

So

=VALUE(LEFT(C1,FIND(" ",C1,8))) 

returns 40671 in this example – in Excel’s 1900 date system the date serial number for May 5, 2011.

Case #2

If the length of C1 is not greater than 10 characters, we still need to distinguish between a text entry or a value entry which I have chosen to do with =ISTEXT and, where the if condition is TRUE (as for C2) apply =DATE which takes three parameters, here provided by:

=RIGHT(C2,4)  

Takes the last four characters of C2, hence 2011 in this example.

=MID(C2,4,2) 

Starting at the fourth character, takes the next two characters of C2, hence 05 in this example (representing May).

=LEFT(C2,2))  

Takes the first two characters of C2, hence 08 in this example (representing the 8th day of the month). Date is not a text function so does not need to be wrapped in =VALUE.

Taken together

=DATE(RIGHT(C2,4),MID(C2,4,2),LEFT(C2,2)) 

also returns 40671 in this example, but from different input from Case #1.

Case #3

Is simple because already a date serial number, so just

=C2  

is sufficient.

Put the above together to cover all three cases in a single formula:

=IF(LEN(C1)>10,VALUE(LEFT(C1,FIND(" ",C1,8))),IF(ISTEXT(C1),DATE(RIGHT(C1,4),MID(C1,4,2),LEFT(C1,2)),C1))  

as applied in ColumnF (formatted to suit OP) or in General format (to show values are integers) in ColumnH:

There is a way to catch the error directly in the except clause with ConnectionResetError, better to isolate the right error. This example also catches the timeout.

from urllib.request import urlopen 
from socket import timeout

url = "http://......"
try: 
    string = urlopen(url, timeout=5).read()
except ConnectionResetError:
    print("==> ConnectionResetError")
    pass
except timeout: 
    print("==> Timeout")
    pass

If the browser that you are planning to use is Mozilla (Addon development) (not sure of chrome) you can use the following method in Javascript

function DOM( string )
{
    var {Cc, Ci} = require("chrome");
    var parser = Cc["@mozilla.org/xmlextras/domparser;1"].createInstance(Ci.nsIDOMParser);
    console.log("PARSING OF DOM COMPLETED ...");
    return (parser.parseFromString(string, "text/html"));
};

Hope this helps

For simply checking against Object or Array without additional function call (speed). As also posted here.

isArray()

isArray = function(a) {
    return (!!a) && (a.constructor === Array);
};
console.log(isArray(        )); // false
console.log(isArray(    null)); // false
console.log(isArray(    true)); // false
console.log(isArray(       1)); // false
console.log(isArray(   'str')); // false
console.log(isArray(      {})); // false
console.log(isArray(new Date)); // false
console.log(isArray(      [])); // true

isLiteralObject() - Note: use for Object literals only, as it returns false for custom objects, like new Date or new YourCustomObject.

isLiteralObject = function(a) {
    return (!!a) && (a.constructor === Object);
};
console.log(isLiteralObject(        )); // false
console.log(isLiteralObject(    null)); // false
console.log(isLiteralObject(    true)); // false
console.log(isLiteralObject(       1)); // false
console.log(isLiteralObject(   'str')); // false
console.log(isLiteralObject(      [])); // false
console.log(isLiteralObject(new Date)); // false
console.log(isLiteralObject(      {})); // true

I discovered today that we can now debug Javascript With the developer tool bar plugins integreted in IE 8.

• Click ? Tools on the toolbar, to the right of the tabs.
• Select Developer Tools. The Developer Tools dialogue should open.
• Click the Script tab in the dialogue.
• Click the Start Debugging button.

You can use watch, breakpoint, see the call stack etc, similarly to debuggers in professional browsers.

You can also use the statement debugger; in your JavaScript code the set a breakpoint.

Updated for pandas 0.20 given that ix is deprecated. This demonstrates not only how to use loc, iloc, at, iat, set_value, but how to accomplish, mixed positional/label based indexing.

loc - label based
Allows you to pass 1-D arrays as indexers. Arrays can be either slices (subsets) of the index or column, or they can be boolean arrays which are equal in length to the index or columns.

Special Note: when a scalar indexer is passed, loc can assign a new index or column value that didn't exist before.

# label based, but we can use position values
# to get the labels from the index object
df.loc[df.index[2], 'ColName'] = 3

df.loc[df.index[1:3], 'ColName'] = 3

iloc - position based
Similar to loc except with positions rather that index values. However, you cannot assign new columns or indices.

# position based, but we can get the position
# from the columns object via the `get_loc` method
df.iloc[2, df.columns.get_loc('ColName')] = 3

df.iloc[2, 4] = 3

df.iloc[:3, 2:4] = 3

at - label based
Works very similar to loc for scalar indexers. Cannot operate on array indexers. Can! assign new indices and columns.

Advantage over loc is that this is faster.
Disadvantage is that you can't use arrays for indexers.

# label based, but we can use position values
# to get the labels from the index object
df.at[df.index[2], 'ColName'] = 3

df.at['C', 'ColName'] = 3

iat - position based
Works similarly to iloc. Cannot work in array indexers. Cannot! assign new indices and columns.

Advantage over iloc is that this is faster.
Disadvantage is that you can't use arrays for indexers.

# position based, but we can get the position
# from the columns object via the `get_loc` method
IBM.iat[2, IBM.columns.get_loc('PNL')] = 3

set_value - label based
Works very similar to loc for scalar indexers. Cannot operate on array indexers. Can! assign new indices and columns

Advantage Super fast, because there is very little overhead!
Disadvantage There is very little overhead because pandas is not doing a bunch of safety checks. Use at your own risk. Also, this is not intended for public use.

# label based, but we can use position values
# to get the labels from the index object
df.set_value(df.index[2], 'ColName', 3)

set_value with takable=True - position based
Works similarly to iloc. Cannot work in array indexers. Cannot! assign new indices and columns.

Advantage Super fast, because there is very little overhead!
Disadvantage There is very little overhead because pandas is not doing a bunch of safety checks. Use at your own risk. Also, this is not intended for public use.

# position based, but we can get the position
# from the columns object via the `get_loc` method
df.set_value(2, df.columns.get_loc('ColName'), 3, takable=True)

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

2 lines code and you are done:

$oDate = new DateTime("2019-11-23");

// now your date object has been updated with last day of month    
$oDate->setDate($oDate->format("Y"),$oDate->format("m"),$oDate->format("t"));

// or to just echo you can skip the above line using this
echo $oDate->format("Y-m-t");

This one really works. Also has the benefit that you can use media queries to easily turn off the horizontal style — for instance if you want to stack them vertically when on mobile phone.

Any of LinearLayout.LayoutParams and TableLayout.LayoutParams worked for me, for buttons the right one is TableRow.LayoutParams. That is:

            TableRow.LayoutParams buttonParams = new TableRow.LayoutParams(
                    TableRow.LayoutParams.MATCH_PARENT,
                    TableRow.LayoutParams.WRAP_CONTENT, 1f);

About using MATCH_PARENT or WRAP_CONTENT be the same.

As in:

In [3]: os.path.exists('/d/temp')
Out[3]: True

Probably toss in a os.path.isdir(...) to be sure.

First off, it is perfectly feasible to use R successfully for years and not need to know the answer to this question. R handles the differences between the (usual) numerics and integers for you in the background.

> is.numeric(1)

[1] TRUE

> is.integer(1)

[1] FALSE

> is.numeric(1L)

[1] TRUE

> is.integer(1L)

[1] TRUE

(Putting capital 'L' after an integer forces it to be stored as an integer.)

As you can see "integer" is a subset of "numeric".

Integers only go to a little more than 2 billion, while the other numerics can be much bigger. They can be bigger because they are stored as double precision floating point numbers. This means that the number is stored in two pieces: the exponent (like 308 above, except in base 2 rather than base 10), and the "significand" (like 1.797693 above).

Note that 'is.integer' is not a test of whether you have a whole number, but a test of how the data are stored.

One thing to watch out for is that the colon operator, :, will return integers if the start and end points are whole numbers. For example, 1:5 creates an integer vector of numbers from 1 to 5. You don't need to append the letter L.

Starting with PHP 8 (2020-11-24), you can use str_contains:

if (str_contains('www.domain.com/car/', 'car')) {
   echo 'car is exist';
} else {
   echo 'no cars';
}

Simply put, if an exception or error is thrown, something's wrong. It may not be something very wrong, but creating, throwing, and catching errors and exceptions just for the sake of using goto statements is not a good idea, and it's rarely done. 99% of the time, there was a problem somewhere.

Problems need to be dealt with. Just like how it is in life, in programming, if you just leave problems alone and try to ignore them, they don't just go away on their own a lot of times; instead they get bigger and multiply. To prevent a problem from growing on you and striking again further down the road, you either 1) eliminate it and clean up the mess afterwards, or 2) contain it and clean up the mess afterwards.

Just ignoring exceptions and errors and leaving them be like that is a good way to experience memory leaks, outstanding database connections, needless locks on file permissions, etc.

On rare occasions, the problem is so miniscule, trivial, and - aside from needing a try...catch block - self-contained, that there really is just no mess to be cleaned up afterwards. These are the only occasions when this best practice doesn't necessarily apply. In my experience, this has generally meant that whatever the code is doing is basically petty and forgoable, and something like retry attempts or special messages are worth neither the complexity nor holding the thread up on.

At my company, the rule is to almost always do something in a catch block, and if you don't do anything, then you must always place a comment with a very good reason why not. You must never pass or leave an empty catch block when there is anything to be done.

Multiple folks have already pointed that

$ screen -ls

would list the screen sessions.

Here is another trick that may be useful to you.

If you add the following command as a last line in your .bashrc file on server xxx, then it will automatically reconnect to your screen session on login.

screen -d -r

Hope you find it useful.

Not a direct answer to your question.. But following is the only syntax that used to work for me -

data: '{"winNumber": "' + win + '"}',

And the parameter-name match with the argument of the server method

You can directly plot the lines you want by feeding the plot command with the corresponding data (boundaries of the segments):

plot([x1, x2], [y1, y2], color='k', linestyle='-', linewidth=2)

(of course you can choose the color, line width, line style, etc.)

From your example:

import numpy as np
import matplotlib.pyplot as plt

np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")


# draw vertical line from (70,100) to (70, 250)
plt.plot([70, 70], [100, 250], 'k-', lw=2)

# draw diagonal line from (70, 90) to (90, 200)
plt.plot([70, 90], [90, 200], 'k-')

plt.show()

A trick I learned from this PR if you don't want to define it as a static final variable but want to save a bit of overhead and guarantee thread safe.

private static final ThreadLocal<ObjectMapper> om = new ThreadLocal<ObjectMapper>() {
    @Override
    protected ObjectMapper initialValue() {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        return objectMapper;
    }
};

public static ObjectMapper getObjectMapper() {
    return om.get();
}

file = open("filename.txt", newline='')
for row in self.data:
    print(row)

Save data to a variable(file), so you need a with.

You can use your own isEmpty (for multiple collection) method too. Add this your Util class.

public static boolean isEmpty(Collection... collections) {
    for (Collection collection : collections) {
        if (null == collection || collection.isEmpty())
            return true;
    }

It seems that one of the most common reasons this happens is if you install a new version of PostgreSQL without stopping the service of an existing installation. This was a particular headache of mine, too. Before installing or upgrading, particularly on OS X and using the one click installer from Enterprise DB, make sure you check the status of the old installation before proceeding.

Use the pdfpages package.

\usepackage{pdfpages}

To include all the pages in the PDF file:

\includepdf[pages=-]{myfile.pdf}

To include just the first page of a PDF:

\includepdf[pages={1}]{myfile.pdf}

You need to split the string:

>>> s = 'http://www.domain.com/?s=some&two=20'
>>> s.split('&')
['http://www.domain.com/?s=some', 'two=20']

That will return a list as you can see so you can do:

>>> s2 = s.split('&')[0]
>>> print s2
http://www.domain.com/?s=some

it's best and safest to use pgrep -f with kill, or just pkill -f, greping ps's output can go wrong.

Unlike using ps | grep with which you need to filter out the grep line by adding | grep -v or using pattern tricks, pgrep just won't pick itself by design.

Moreover, should your pattern appear in ps's UID/USER, SDATE/START or any other column, you'll get unwanted processes in the output and kill them, pgrep+pkill don't suffer from this flaw.

also I found that killall -r/ -regexp didn't work with my regular expression.

pkill -f "^python3 path/to/my_script$"

Another way to do this!

When Node.js is not installed using the msi installer, npm needs to be setup manually.

setting up npm

First, let's say we have the node.exe file located in the folder c:\nodejs. Now to setup npm-

1. Download the latest npm release from GitHub (https://github.com/npm/npm/releases)
2. Create folders c:\nodejs\node_modules and c:\nodejs\node_modules\npm
3. Unzip the downloaded zip file in c:\nodejs\node_modules\npm folder
4. Copy npm and npm.cmd files from c:\nodejs\node_modules\npm\bin to c:\nodejs folder

In order to test npm, open cmd.exe change working directory to c:\nodejs and type npm --version. You will see the version of npm if it is setup correctly.

Once setup is done, it can be used to install/uninstall packages locally or globally. For more information on using npm visit https://docs.npmjs.com/.

As the final step you can add node's folder path c:\nodejs to the path environment variable so that you don't have to specify full path when running node.exe and npm at command prompt.

Standard C doesn't define binary constants. There's a GNU (I believe) extension though (among popular compilers, clang adapts it as well): the 0b prefix:

int foo = 0b1010;

If you want to stick with standard C, then there's an option: you can combine a macro and a function to create an almost readable "binary constant" feature:

#define B(x) S_to_binary_(#x)

static inline unsigned long long S_to_binary_(const char *s)
{
        unsigned long long i = 0;
        while (*s) {
                i <<= 1;
                i += *s++ - '0';
        }
        return i;
}

And then you can use it like this:

int foo = B(1010);

If you turn on heavy compiler optimizations, the compiler will most likely eliminate the function call completely (constant folding) or will at least inline it, so this won't even be a performance issue.

Proof:

The following code:

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


#define B(x) S_to_binary_(#x)

static inline unsigned long long S_to_binary_(const char *s)
{
    unsigned long long i = 0;
    while (*s) {
        i <<= 1;
        i += *s++ - '0';
    }
    return i;
}

int main()
{
    int foo = B(001100101);

    printf("%d\n", foo);

    return 0;
}

has been compiled using clang -o baz.S baz.c -Wall -O3 -S, and it produced the following assembly:

    .section    __TEXT,__text,regular,pure_instructions
    .globl  _main
    .align  4, 0x90

So clang completely eliminated the call to the function, and replaced its return value with 101. Neat, huh?

For those interested, Spring MVC (3.x at least) returns a 400 in this case, which seems wrong to me.

I tested several Google URLs (accounts.google.com) and removed required parameters, and they generally return a 404 in this case.

I would copy Google.

If you're using multiple slides, and you can use jQuery, you can do the follow to deal with multiple sliders easily:

function updateRangeInput(elem) {_x000D_
  $(elem).next().val($(elem).val());_x000D_
}

input { padding: 8px; border: 1px solid #ddd; color: #555; display: block; }_x000D_
input[type=text] { width: 100px; }_x000D_
input[type=range] { width: 400px; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<input type="range" min="0" max="100" oninput="updateRangeInput(this)" value="0">_x000D_
<input type="text" value="0">_x000D_
_x000D_
<input type="range" min="0" max="100" oninput="updateRangeInput(this)" value="50">_x000D_
<input type="text" value="50">

Also, by using oninput on the <input type='range'> you'll receive events while dragging the range.

A somewhat important distinction is if the element is an input or not. If an input you can use:

$('#selector').val().length;

otherwise if the element is a different html element like a paragraph or list item div etc, you must use

$('#selector').text().length;

Sorting in an ORDER BY is done by the first column, and then by each additional column in the specified statement.

For instance, consider the following data:

Column1    Column2
=======    =======
1          Smith
2          Jones
1          Anderson
3          Andrews

The query

SELECT Column1, Column2 FROM thedata ORDER BY Column1, Column2

would first sort by all of the values in Column1

and then sort the columns by Column2 to produce this:

Column1    Column2
=======    =======
1          Anderson
1          Smith
2          Jones
3          Andrews

In other words, the data is first sorted in Column1 order, and then each subset (Column1 rows that have 1 as their value) are sorted in order of the second column.

The difference between the two statements you posted is that the rows in the first one would be sorted first by prod_price (price order, from lowest to highest), and then by order of name (meaning that if two items have the same price, the one with the lower alpha value for name would be listed first), while the second would sort in name order only (meaning that prices would appear in order based on the prod_name without regard for price).

The error is in this line: (% load pygmentize %}, an invalid tag. Change it to {% load pygmentize %}

If you try to be aware of i18n the solution get even more complicated.

The problem is that in other languages the suffix may depend not only on the number itself, but also on the noun it counts. For example in Russian it would be "2-?? ????", but "2-?? ??????" (these mean "2nd day", but "2nd week"). This is not apply if we formatting only days, but in a bit more generic case you should be aware of complexity.

I think nice solution (I didn't have time to actually implement) would be to extend SimpleDateFormetter to apply Locale-aware MessageFormat before passing to the parent class. This way you would be able to support let say for March formats %M to get "3-rd", %MM to get "03-rd" and %MMM to get "third". From outside this class looks like regular SimpleDateFormatter, but supports more formats. Also if this pattern would be by mistake applied by regular SimpleDateFormetter the result would be incorrectly formatted, but still readable.

To use a MySQL AUTO_INCREMENT column, you are supposed to use an IDENTITY strategy:

@Id @GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;

Which is what you'd get when using AUTO with MySQL:

@Id @GeneratedValue(strategy=GenerationType.AUTO)
private Long id;

Which is actually equivalent to

@Id @GeneratedValue
private Long id;

In other words, your mapping should work. But Hibernate should omit the id column in the SQL insert statement, and it is not. There must be a kind of mismatch somewhere.

Did you specify a MySQL dialect in your Hibernate configuration (probably MySQL5InnoDBDialect or MySQL5Dialect depending on the engine you're using)?

Also, who created the table? Can you show the corresponding DDL?

Follow-up: I can't reproduce your problem. Using the code of your entity and your DDL, Hibernate generates the following (expected) SQL with MySQL:

insert 
into
    Operator
    (active, password, username) 
values
    (?, ?, ?)

Note that the id column is absent from the above statement, as expected.

To sum up, your code, the table definition and the dialect are correct and coherent, it should work. If it doesn't for you, maybe something is out of sync (do a clean build, double check the build directory, etc) or something else is just wrong (check the logs for anything suspicious).

Regarding the dialect, the only difference between MySQL5Dialect or MySQL5InnoDBDialect is that the later adds ENGINE=InnoDB to the table objects when generating the DDL. Using one or the other doesn't change the generated SQL.

Direct Javascript calls between frames and/or windows are only allowed if they conform to the same-origin policy. If your window and iframe share a common parent domain you can set document.domain to "domain lower") one or both such that they can communicate. Otherwise you'll need to look into something like the postMessage() API.

Don't video encoding algorithms like MPEG compute the difference between each frame of a video so they can just encode the delta? You might look into how video encoding algorithms compute those frame differences.

Try adding a BindingResult parameter to methods annotated with @RequestMapping which have a @ModelAttribute annotated parameters. After each @ModelAttribute parameter, Spring looks for a BindingResult in the next parameter position (order is important).

So try changing:

@RequestMapping(method = RequestMethod.POST)
public String loadCharts(HttpServletRequest request, ModelMap model, @ModelAttribute("sideForm") Chart chart) 
...

To:

@RequestMapping(method = RequestMethod.POST)
public String loadCharts(@ModelAttribute("sideForm") Chart chart, BindingResult bindingResult, HttpServletRequest request, ModelMap model) 
...

This is not the most glamorous way but works.

(must have using System.Linq;)

 int maxValue = anArray.Max();
 int maxIndex = anArray.ToList().IndexOf(maxValue);

You can check whether the variable is a number like this: $val -is [int]

This will work for numeric values, but not if the number is wrapped in quotes:

1 -is [int]
True
"1" -is [int]
False

dynamic_cast is known to be inefficient. It traverses up the inheritance hierarchy, and it is the only solution if you have multiple levels of inheritance, and need to check if an object is an instance of any one of the types in its type hierarchy.

But if a more limited form of instanceof that only checks if an object is exactly the type you specify, suffices for your needs, the function below would be a lot more efficient:

template<typename T, typename K>
inline bool isType(const K &k) {
    return typeid(T).hash_code() == typeid(k).hash_code();
}

Here's an example of how you'd invoke the function above:

DerivedA k;
Base *p = &k;

cout << boolalpha << isType<DerivedA>(*p) << endl;  // true
cout << boolalpha << isType<DerivedB>(*p) << endl;  // false

You'd specify template type A (as the type you're checking for), and pass in the object you want to test as the argument (from which template type K would be inferred).

• The children of a row-flexbox container automatically fill the container's vertical space.

• Specify flex: 1; for a child if you want it to fill the remaining horizontal space:

If that empty Date really bugs you, you can also to create a simpler Time structure:

// more work is required to make this even close to production ready
class Time
{
    // TODO: don't forget to add validation
    public int Hours   { get; set; }
    public int Minutes { get; set; }
    public int Seconds { get; set; }

    public override string ToString()
    {  
        return String.Format(
            "{0:00}:{1:00}:{2:00}",
            this.Hours, this.Minutes, this.Seconds);
    }
}

Or, why to bother: if you don't need to do any calculation with that information, just store it as String.

$xml = $( $.parseXML( xml ) );

$xml.find("<<your_xml_tag_name>>").each(function(index,elem){
    // elem = found XML element
});

For me what did the trick was running the command

git config auto.crlf false

inside the folder of the project, I wanted it specifically for one project.

That command changed the file in path {project_name}/.git/config (fyi .git is a hidden folder) by adding the lines

[auto]
    crlf = false

at the end of the file. I suppose changing the file does the same trick as well.

if you don't want to start nginx as root.

first creat log file :

sudo touch /var/log/nginx/error.log

and then fix permissions:

sudo chown -R www-data:www-data /var/log/nginx

sudo find /var/log/nginx -type f -exec chmod 666 {} \;

sudo find /var/log/nginx -type d -exec chmod 755 {} \;

Well you can just call this link

The proper function is int fileno(FILE *stream). It can be found in <stdio.h>, and is a POSIX standard but not standard C.

Just spent 4 hours with this problem. Finally realized that you must not use zero as view id. You would think that it is allowed as NO_ID == -1, but things tend to go haywire if you give it to your view...

Null termination is a bad design pattern best left in the history books. There's still plenty of inertia behind c-strings, so it can't be avoided there. But there's no reason to use it in the OP's example.

Don't use any terminator, and use sizeof(array) / sizeof(array[0]) to get the number of elements.

All tables within the bootstrap stretch according to their container, which you can easily do by placing your table inside a .span* grid element of your choice. If you wish to remove this property you can create your own table class and simply add it to the table you want to expand with the content within:

.table-nonfluid {
   width: auto !important;
}

You can add this class inside your own stylesheet and simply add it to the container of your table like so:

<table class="table table-nonfluid"> ... </table>

This way your change won't affect the bootstrap stylesheet itself (you might want to have a fluid table somewhere else in your document).

When you use varargs, it can result in the creation of an Object[] to hold the arguments.

Due to escape analysis, the JIT can optimise away this array creation. (One of the few times I have found it does so) Its not guaranteed to be optimised away, but I wouldn't worry about it unless you see its an issue in your memory profiler.

AFAIK @SafeVarargs suppresses a warning by the compiler and doesn't change how the JIT behaves.

For this you need to create a function that adds the function to an object, then it will execute depending on the amount of arguments you send to the function:

<script > 
//Main function to add the methods
function addMethod(object, name, fn) {
  var old = object[name];
  object[name] = function(){
    if (fn.length == arguments.length)
      return fn.apply(this, arguments)
    else if (typeof old == 'function')
      return old.apply(this, arguments);
  };
}


?  var ninjas = {
   values: ["Dean Edwards", "Sam Stephenson", "Alex Russell"]
};

//Here we declare the first function with no arguments passed
  addMethod(ninjas, "find", function(){
    return this.values;
});

//Second function with one argument
  addMethod(ninjas, "find", function(name){
    var ret = [];
    for (var i = 0; i < this.values.length; i++)
      if (this.values[i].indexOf(name) == 0)
        ret.push(this.values[i]);
    return ret;
  });

//Third function with two arguments
  addMethod(ninjas, "find", function(first, last){
    var ret = [];
    for (var i = 0; i < this.values.length; i++)
      if (this.values[i] == (first + " " + last))
        ret.push(this.values[i]);
    return ret;
  });


//Now you can do:
ninjas.find();
ninjas.find("Sam");
ninjas.find("Dean", "Edwards")
</script>

Rather than using the ssh:// protocol prefix, you can continue using the conventional URL form for accessing git over SSH, with one small change. As a reminder, the conventional URL is:

git@host:path/to/repo.git

To specify an alternative port, put brackets around the user@host part, including the port:

[git@host:port]:path/to/repo.git

But if the port change is merely temporary, you can tell git to use a different SSH command instead of changing your repository’s remote URL:

export GIT_SSH_COMMAND='ssh -p port'
git clone git@host:path/to/repo.git # for instance

Why not so?:

set host=%COMPUTERNAME%
echo %host%

Seems to be identical just in case that SQL server will not try to read data which is not required for the query, the optimizer is clever enough

It can have sense when join on complex query (i.e which have joings, groupings etc itself) then, yes, it is better to specify required fields.

But there is one more point. If the query is simple there is no difference but EVERY extra action even which is supposed to improve performance makes optimizer works harder and optimizer can fail to get the best plan in time and will run not optimal query. So extras select can be a such action which can even decrease performance

This is the SQL Order of execution of a Query,

You can check order of execution with examples from this article.

For you question below lines might be helpful and directly got from this article.

3. GROUP BY --> The remaining rows after the WHERE constraints are applied are then grouped based on common values in the column specified in the GROUP BY clause. As a result of the grouping, there will only be as many rows as there are unique values in that column. Implicitly, this means that you should only need to use this when you have aggregate functions in your query.

4. HAVING --> If the query has a GROUP BY clause, then the constraints in the HAVING clause are then applied to the grouped rows, discard the grouped rows that don't satisfy the constraint. Like the WHERE clause, aliases are also not accessible from this step in most databases.

I had the same problem. My customer ordered me Python 3.4 script that updates XLS (not XLSX) Excel files.

The 1st package xlrd was installed by "pip install" without problems in my Python home.

The 2nd one xlwt needed to say "pip install xlwt-future" to be compatible.

The 3rd one xlutils has no support for Python 3, but I adapted it a little bit and now it works at least for dummy script:

#!C:\Python343\python
from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils
from xlrd import open_workbook # http://pypi.python.org/pypi/xlrd
from xlwt import easyxf # http://pypi.python.org/pypi/xlwt

file_path = 'C:\Dev\Test_upd.xls'
rb = open_workbook('C:\Dev\Test.xls',formatting_info=True)
r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file
wb = copy(rb) # a writable copy (I can't read values out of this, only write to it)
w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy
w_sheet.write(1, 1, 'Value')
wb.save(file_path)

I attached the file here: http://ifolder.su/43507580

Write to [email protected] if it got expired.

P.S.: Some functions are not called in the dummy example, so maybe they will need for an adaptation also. Who wants to do it, fix exceptions one-by-one with a google help. It's not a very difficult task, because the package code is small...

You can also use the transform: scale("") option.

The problem is that you're not initializing the pointer. You've created a pointer to "anywhere you want"—which could be the address of some other variable, or the middle of your code, or some memory that isn't mapped at all.

You need to create an int variable somewhere in memory for the int * variable to point at.

Your second example does this, but it does other things that aren't relevant here. Here's the simplest thing you need to do:

int main(){
    int variable;
    int *ptr = &variable;
    *ptr = 20;
    printf("%d", *ptr);
    return 0;
}

Here, the int variable isn't initialized—but that's fine, because you're just going to replace whatever value was there with 20. The key is that the pointer is initialized to point to the variable. In fact, you could just allocate some raw memory to point to, if you want:

int main(){
    void *memory = malloc(sizeof(int));
    int *ptr = (int *)memory;
    *ptr = 20;
    printf("%d", *ptr);
    free(memory);
    return 0;
}

If you are ok with small tweak - we know that bootstrap works with a width of 12

<div class="row">
      <div class="col-md-1">
            Keep it blank it becomes left offset
      </div> 
      <div class="col-md-5">
      </div>
      <div class="col-md-5">
      </div>
      <div class="col-md-1">
            Keep it blank it becomes right offset
      </div
</div>

I am sure there is a better way to do this, but i was in a hurry so used this trick

Try using xmltype.createxml(xml).

As in,

select extract(xmltype.createxml(xml), '//fax').getStringVal() from mytab;

It worked for me.

If you want to improve or manipulate even further.

Try something like this.

Select *
from xmltable(xmlnamespaces('some-name-space' as "ns", 
                                  'another-name-space' as "ns1",
                           ), 
                    '/ns/ns1/foo/bar'
                    passing xmltype.createxml(xml) 
                    columns id varchar2(10) path '//ns//ns1/id',
                            idboss varchar2(500) path '//ns0//ns1/idboss',
                            etc....

                    ) nice_xml_table

Hope it helps someone.

I ran into the problem of not having set my sources root folder (project window--right click folder, mark directory as > sources root). If you don't set this IDEA doesn't parse the file.

SELECT CONVERT_TZ() will work for that.but its not working for me.

Why, what error do you get?

SELECT CONVERT_TZ(displaytime,'GMT','MET');

should work if your column type is timestamp, or date

http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_convert-tz

Test how this works:

SELECT CONVERT_TZ(a_ad_display.displaytime,'+00:00','+04:00');

Check your timezone-table

SELECT * FROM mysql.time_zone;
SELECT * FROM mysql.time_zone_name;

http://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html

If those tables are empty, you have not initialized your timezone tables. According to link above you can use mysql_tzinfo_to_sql program to load the Time Zone Tables. Please try this

shell> mysql_tzinfo_to_sql /usr/share/zoneinfo

or if not working read more: http://dev.mysql.com/doc/refman/5.5/en/mysql-tzinfo-to-sql.html

No need to remember flags. Remember that you can always do:

subprocess.call(["chmod", "a-w", "file/path])

Not portable but easy to write and remember:

• u - user
• g - group
• o - other
• a - all
• + or - (add or remove permission)
• r - read
• w - write
• x - execute

Refer man chmod for additional options and more detailed explanation.

The above answers will work, but just in case you want a different approach, try classname: https://github.com/JedWatson/classnames

You just use an ImageButton and make the background whatever you want and set the icon as the src.

<ImageButton
    android:id="@+id/ImageButton01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/album_icon"
    android:background="@drawable/round_button" />

If you want to pass the variable to your proxy backend, you have to set it with the proxy module.

location / {
    proxy_pass                      http://example.com;
    proxy_set_header                Host example.com;
    proxy_set_header                HTTP_Country-Code $geoip_country_code;
    proxy_pass_request_headers      on;
}

And now it's passed to the proxy backend.

import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;

private String getDateTime() {
    DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
    Date date = new Date();
    return dateFormat.format(date);
}

  {
    "name": "Pizza",
    "price": "10",
    "quantity": "7"
  },
  {
    "name": "Cerveja",
    "price": "12",
    "quantity": "5"
  },
  {
    "name": "Hamburguer",
    "price": "10",

Note This is an improvement in @user3516549 answer and I have check it on Moto G3 with Android 6.0.1
I have this issue so I have tried answer of @user3516549 but in some cases it was not working properly. I have found that in Android 6.0(or above) when we start gallery image pick intent then a screen will open that shows recent images when user select image from this list we will get uri as

content://com.android.providers.media.documents/document/image%3A52530

while if user select gallery from sliding drawer instead of recent then we will get uri as

content://media/external/images/media/52530

So I have handle it in getRealPathFromURI_API19()

public static String getRealPathFromURI_API19(Context context, Uri uri) {
        String filePath = "";
        if (uri.getHost().contains("com.android.providers.media")) {
            // Image pick from recent 
            String wholeID = DocumentsContract.getDocumentId(uri);

            // Split at colon, use second item in the array
            String id = wholeID.split(":")[1];

            String[] column = {MediaStore.Images.Media.DATA};

            // where id is equal to
            String sel = MediaStore.Images.Media._ID + "=?";

            Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                    column, sel, new String[]{id}, null);

            int columnIndex = cursor.getColumnIndex(column[0]);

            if (cursor.moveToFirst()) {
                filePath = cursor.getString(columnIndex);
            }
            cursor.close();
            return filePath;
        } else {
            // image pick from gallery 
           return  getRealPathFromURI_BelowAPI11(context,uri)
        }

    }

EDIT1 : if you are trying to get image path of file in external sdcard in higher version then check my question

EDIT2 Here is complete code with handling virtual files and host other than com.android.providers I have tested this method with content://com.adobe.scan.android.documents/document/

Using pure bash :

$ cat file.txt
US/Central - 10:26 PM (CST)
$ while read a b time x; do [[ $b == - ]] && echo $time; done < file.txt

another solution with bash regex :

$ [[ "US/Central - 10:26 PM (CST)" =~ -[[:space:]]*([0-9]{2}:[0-9]{2}) ]] &&
    echo ${BASH_REMATCH[1]}

another solution using grep and look-around advanced regex :

$ echo "US/Central - 10:26 PM (CST)" | grep -oP "\-\s+\K\d{2}:\d{2}"

another solution using sed :

$ echo "US/Central - 10:26 PM (CST)" |
    sed 's/.*\- *\([0-9]\{2\}:[0-9]\{2\}\).*/\1/'

another solution using perl :

$ echo "US/Central - 10:26 PM (CST)" |
    perl -lne 'print $& if /\-\s+\K\d{2}:\d{2}/'

and last one using awk :

$ echo "US/Central - 10:26 PM (CST)" |
    awk '{for (i=0; i<=NF; i++){if ($i == "-"){print $(i+1);exit}}}'

This flexbox principle also works horizontally

During calculations of flex bases and flexible lengths, auto margins are treated as 0.
Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Setting an automatic left margin for the Last Item will do the work.

.last-item {
  margin-left: auto;
}

Code Example:

.container {_x000D_
  display: flex;_x000D_
  width: 400px;_x000D_
  outline: 1px solid black;_x000D_
}_x000D_
_x000D_
p {_x000D_
  height: 50px;_x000D_
  width: 50px;_x000D_
  margin: 5px;_x000D_
  background-color: blue;_x000D_
}_x000D_
_x000D_
.last-item {_x000D_
  margin-left: auto;_x000D_
}

<div class="container">_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p class="last-item"></p>_x000D_
</div>

sklearn.linear_model.LinearRegression will do it:

from sklearn import linear_model
clf = linear_model.LinearRegression()
clf.fit([[getattr(t, 'x%d' % i) for i in range(1, 8)] for t in texts],
        [t.y for t in texts])

Then clf.coef_ will have the regression coefficients.

sklearn.linear_model also has similar interfaces to do various kinds of regularizations on the regression.

The EASIEST (and definitely the quickest) way to do requires WINRAR, 7zip or similar archiving software:

1. Find the project folder in windows explorer - double click to open this folder.

2. Create a new folder and name it "Backup."

3. While still in the project folder, select all files / folders, except the "backup" folder.

4. Right-click and select "add to archive" or "create archive" (command will be different depending on your archiving software)

5. Name the archive and click ok.

6. Move this archive to the "Backup" folder.

You're Done - to open the backup archive, open "Backup" folder and right-click on the backup file. Select "Extract" or create a new folder to which the files will be extracted and hit "ok" then open the project as you normally would from Android Studio, etc.

But, why not use css? That way you can keep the button as a submit type.

html:

<input type="submit" value="go" />

css:

button, input[type="submit"] {
    background:url(/images/submit.png) no-repeat;"
}

Works like a charm.

EDIT: If you want to remove the default button styles, you can use the following css:

button, input[type="submit"]{
    color: inherit;
    border: none;
    padding: 0;
    font: inherit;
    cursor: pointer;
    outline: inherit;
}

You can choose any extension in the world if you setup Apache correctly. You could use .html to do PHP if you set up in your Apache config.

In conclusion, extension has nothing to do with the app or website itself. You can use the one you want, but normaly, use .php (to not reinvent the wheel)

But in 2019, you should use routing and forgot about extension at the end.

I recommend you using Laravel.

In answer to @KingCrunch: True, Apache not use it by default but you can easily use it if you change config. But this it not recommended since everybody know that it not really an option.

I already saw .html files that executed PHP using the html extension.

A simple code to list all the Items from DynamoDB Table by specifying the region of AWS Service.

import boto3

dynamodb = boto3.resource('dynamodb', region_name='ap-south-1')
table = dynamodb.Table('puppy_store')
response = table.scan()
items = response['Items']

# Prints All the Items at once
print(items)

# Prints Items line by line
for i, j in enumerate(items):
    print(f"Num: {i} --> {j}")

By "camera position," it sounds like you want to adjust the elevation and the azimuth angle that you use to view the 3D plot. You can set this with ax.view_init. I've used the below script to first create the plot, then I determined a good elevation, or elev, from which to view my plot. I then adjusted the azimuth angle, or azim, to vary the full 360deg around my plot, saving the figure at each instance (and noting which azimuth angle as I saved the plot). For a more complicated camera pan, you can adjust both the elevation and angle to achieve the desired effect.

    from mpl_toolkits.mplot3d import Axes3D
    ax = Axes3D(fig)
    ax.scatter(xx,yy,zz, marker='o', s=20, c="goldenrod", alpha=0.6)
    for ii in xrange(0,360,1):
        ax.view_init(elev=10., azim=ii)
        savefig("movie%d.png" % ii)

Web applications are dynamic websites.

According to wikipedia, website is the abstract term of this paradigm.

A website, also written as web site, or simply site, is a set of related web pages typically served from a single web domain. A website is hosted on at least one web server, accessible via a network such as the Internet or a private local area network through an Internet address known as a uniform resource locator (URL). All publicly accessible websites collectively constitute the World Wide Web. (Source: http://en.wikipedia.org/wiki/Website)

Therefore, the Web Application is a type of website regardless of its purpose, in fact, a dynamic website, but the website is not indeed a web application.

In my point of view, all modern websites are web applications, including CMS's. Does anyone in the world still writes manual static html files, I don't think so. Even though, some websites have few static pages, but if they were created dynamically via a CMS, then it is definitely a CMS web application.

If some users of the code have different language settings format might not work. Thus I use the following code that gives the time stamp in format "yyymmdd hhMMss" regardless of language.

Function TimeStamp()

Dim d(1 To 6)
Dim i As Integer


iNow = Now
d(1) = Year(iNow)
d(2) = Month(iNow)
d(3) = Day(iNow)
d(4) = Hour(iNow)
d(5) = Minute(iNow)
d(6) = Second(iNow)

For i = 1 To 6
    If d(i) < 10 Then TimeStamp = TimeStamp & "0"
    TimeStamp = TimeStamp & d(i)
    If i = 3 Then TimeStamp = TimeStamp & " "
Next i

End Function

Quick note: Check if you have other Python versions, if you have removed them, make sure you did that right. If you have Miniconda on your system then Python will not be removed easily.

What worked for me: removed other Python versions and the Miniconda, reinstalled Python and the matplotlib library and everything worked great.

I added opacity to the line, so it seems thinner:

Since we're all guessing, I might as well give mine: I've always thought it stood for Python. That may sound pretty stupid -- what, P for Python?! -- but in my defense, I vaguely remembered this thread [emphasis mine]:

Subject: Claiming (?P...) regex syntax extensions

From: Guido van Rossum ([email protected])

Date: Dec 10, 1997 3:36:19 pm

I have an unusual request for the Perl developers (those that develop the Perl language). I hope this (perl5-porters) is the right list. I am cc'ing the Python string-sig because it is the origin of most of the work I'm discussing here.

You are probably aware of Python. I am Python's creator; I am planning to release a next "major" version, Python 1.5, by the end of this year. I hope that Python and Perl can co-exist in years to come; cross-pollination can be good for both languages. (I believe Larry had a good look at Python when he added objects to Perl 5; O'Reilly publishes books about both languages.)

As you may know, Python 1.5 adds a new regular expression module that more closely matches Perl's syntax. We've tried to be as close to the Perl syntax as possible within Python's syntax. However, the regex syntax has some Python-specific extensions, which all begin with (?P . Currently there are two of them:

(?P<foo>...) Similar to regular grouping parentheses, but the text
matched by the group is accessible after the match has been performed, via the symbolic group name "foo".

(?P=foo) Matches the same string as that matched by the group named "foo". Equivalent to \1, \2, etc. except that the group is referred
to by name, not number.

I hope that this Python-specific extension won't conflict with any future Perl extensions to the Perl regex syntax. If you have plans to use (?P, please let us know as soon as possible so we can resolve the conflict. Otherwise, it would be nice if the (?P syntax could be permanently reserved for Python-specific syntax extensions. (Is there some kind of registry of extensions?)

to which Larry Wall replied:

[...] There's no registry as of now--yours is the first request from outside perl5-porters, so it's a pretty low-bandwidth activity. (Sorry it was even lower last week--I was off in New York at Internet World.)

Anyway, as far as I'm concerned, you may certainly have 'P' with my blessing. (Obviously Perl doesn't need the 'P' at this point. :-) [...]

So I don't know what the original choice of P was motivated by -- pattern? placeholder? penguins? -- but you can understand why I've always associated it with Python. Which considering that (1) I don't like regular expressions and avoid them wherever possible, and (2) this thread happened fifteen years ago, is kind of odd.

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

You can simply run sudo service docker start which will start running your docker server. You can check if you have the docker server by running service --status-all, you should see docker listed.

The issue arose because of not including jar file as part of the project. I was just including it in tomcat lib. Using the below in web.xml works now:

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>
        org.springframework.web.filter.DelegatingFilterProxy
    </filter-class>
</filter>

 <filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<filter>
    <filter-name>CORS</filter-name>
    <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>

    <init-param>
        <param-name>cors.allowOrigin</param-name>
        <param-value>*</param-value>
    </init-param>
    <init-param>
        <param-name>cors.supportsCredentials</param-name>
        <param-value>false</param-value>
    </init-param>
    <init-param>
        <param-name>cors.supportedHeaders</param-name>
        <param-value>accept, authorization, origin</param-value>
    </init-param>
    <init-param>
        <param-name>cors.supportedMethods</param-name>
        <param-value>GET, POST, HEAD, OPTIONS</param-value>
    </init-param>
</filter>


<filter-mapping>
    <filter-name>CORS</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

And the below in your project dependency:

<dependency>
    <groupId>com.thetransactioncompany</groupId>
    <artifactId>cors-filter</artifactId>
    <version>1.3.2</version>
</dependency>

Stopping Event Propagation in some particular elements ma y become dangerous as it may prevent other some scripts from running. So check whether the triggering is from the excluded area from inside the function.

$(document).on('click', function(event) {
  if (!$(event.target).closest('#menucontainer').length) {
    // Hide the menus.
  }
});

Here function is initiated when clicking on document, but it excludes triggering from #menucontainer. For details https://css-tricks.com/dangers-stopping-event-propagation/

You will need to define "special characters", but it's likely that for some string s you mean:

import re
if re.match(r'^\w+$', s):
    # s is good-to-go

If we're going to be as sloppy as to use tolower(), do this:

char blah[] = "blah blah Blah BLAH blAH\0"; int i=0; while(blah[i]|=' ', blah[++i]) {}

But, well, it kinda explodes if you feed it some symbols/numerals, and in general it's evil. Good interview question, though.

It can be detected by storing the previous scrollTop value and comparing the current scrollTop value with it.

JavaScript :

var lastScrollTop = 0;

// element should be replaced with the actual target element on which you have applied scroll, use window in case of no target element.
element.addEventListener("scroll", function(){ // or window.addEventListener("scroll"....
   var st = window.pageYOffset || document.documentElement.scrollTop; // Credits: "https://github.com/qeremy/so/blob/master/so.dom.js#L426"
   if (st > lastScrollTop){
      // downscroll code
   } else {
      // upscroll code
   }
   lastScrollTop = st <= 0 ? 0 : st; // For Mobile or negative scrolling
}, false);

ui-router doesn't track the previous state once it transitions, but the event $stateChangeSuccess is broadcast on the $rootScope when the state changes.

You should be able to catch the prior state from that event (from is the state you're leaving):

$rootScope.$on('$stateChangeSuccess', function (ev, to, toParams, from, fromParams) {
   //assign the "from" parameter to something
});

I think use ref is safe for me, dont need care about some method above.

class Company extends XComponent {
    constructor(props) {
        super(props);
        this.data = {};
    }
    fetchData(data) {
        this.resetState(data);
    }
    render() {
        return (
            <Input ref={c => this.data['name'] = c} type="text" className="form-control" />
        );
    }
}
class XComponent extends Component {
    resetState(obj) {
        for (var property in obj) {
            if (obj.hasOwnProperty(property) && typeof this.data[property] !== 'undefined') {
                if ( obj[property] !== this.data[property].state.value )
                    this.data[property].setState({value: obj[property]});
                else continue;
            }
            continue;
        }
    }
}

You can use

select * 
from transaction 
where (Card_No='123') and (transaction_date = convert(varchar(10),getdate(),101))

In the case you're interested in extremely minor, almost immeasurable performance increases, add a constructor to your Line class, giving you such:

public class Line
{
    public Line(string sku, int qty)
    {
        this.Sku = sku;
        this.Qty = qty;
    }

    public string Sku { get; set; }
    public int Qty    { get; set; }
}

Then create a specialized collection class based on List<Line> with one new method, Add:

public class LineList : List<Line>
{
    public void Add(string sku, int qty)
    {
        this.Add(new Line(sku, qty));
    }
}

Then the code which populates your list gets a bit less verbose by using a collection initializer:

LineList myLines = new LineList
{
    { "ABCD1", 1 },
    { "ABCD2", 1 },
    { "ABCD3", 1 }
};

And, of course, as the other answers state, it's trivial to extract the SKUs into a string array with LINQ:

string[] mySKUsArray = myLines.Select(myLine => myLine.Sku).ToArray();

The typical formula for recalculation of 2D array indices into 1D array index is

index = indexX * arrayWidth + indexY;

Alternatively you can use

index = indexY * arrayHeight + indexX;

(assuming that arrayWidth is measured along X axis, and arrayHeight along Y axis)

Of course, one can come up with many different formulae that provide alternative unique mappings, but normally there's no need to.

In C/C++ languages built-in multidimensional arrays are stored in memory so that the last index changes the fastest, meaning that for an array declared as

int xy[10][10];

element xy[5][3] is immediately followed by xy[5][4] in memory. You might want to follow that convention as well, choosing one of the above two formulae depending on which index (X or Y) you consider to be the "last" of the two.

Try this

frame$twohouses <- ifelse(frame$data>1, 2, 1)
 frame
   data twohouses
1     0         1
2     1         1
3     2         2
4     3         2
5     4         2
6     2         2
7     3         2
8     1         1
9     4         2
10    3         2
11    2         2
12    4         2
13    0         1
14    1         1
15    2         2
16    0         1
17    2         2
18    1         1
19    2         2
20    0         1
21    4         2

Use user.dir key for get project location using java.

Code:

System.out.println("Present Project Directory : "+ System.getProperty("user.dir"));

OutPut:

Present Project Directory :C:\workspace\MyEclipse 10\examples\MySqlMavenDomain

For displaying all systems properties simply use System.getProperties();

Use Key value in System.getProperty("java.version"); for get output.

Code:

Properties properties = System.getProperties();
Enumeration<Object> enumeration = properties.keys();
for (int i = 0; i < properties.size(); i++) {
    Object obj = enumeration.nextElement();
    System.out.println("Key: "+obj+"\tOutPut= "+System.getProperty(obj.toString()));
}

If you want to plot a single line connecting all the points in the list

plt.plot(li[:])

plt.show()

This will plot a line connecting all the pairs in the list as points on a Cartesian plane from the starting of the list to the end. I hope that this is what you wanted.

Using some simple command line (bash scripting):

$ cat /dev/urandom | tr -cd 'a-z0-9,.?/\-' | head -c 30 | xargs
t315,qeqaszwz6kxv?761rf.cj/7gc

$ cat /dev/urandom | tr -cd 'a-z0-9,.?/\-' | head -c 1 | xargs
f

• cat /dev/urandom: get a random stream of char from the kernel
• tr: keep only char char we want
• head: take only the first n chars
• xargs: just for adding a '\n' char

when I started xampp on my windows 10 there were many options available, unfortunately every one of them failed. I ll list them so that you don't go through all of them again.

THINGS THAT DIDN'T WORK

1) i installed xampp initially in a different drive and not c because of UAC issues so i uninstalled Xampp and installed it again in c (didn't work) 2) while reinstalling i deactivated the antivirus as setup said that some installing might not end up properly(realized it doesn't matter :) lmao) 3) i tried to change ports several times of xampp from 80 to some different number like 8080 etc. still nothing happened 4) i then tried using firefox as it is believed that internet explorer or internet edge is not a good browser for xampp 5) after that i went to config file i.e config.inc inside phpmyadmin folder and did some crap as were given in the instructions. Failure it was 6) then i closed laptop and went to sleep(XD srry leave this point) 7) then i tried searching for windows web services in the services.msc to disable it. i couldn't find it

WHAT WORKED

On eighth time i got success.This is what i did 8)In control panel, where you have actions , modules PIDs, Ports you will see Services under which you will see gray boxes which are actually checkboxes but are empty initially. i checked it so that xampp services start and apache services start. now you will see them ticked. After that just change the port of xampp and apache to 80.

I hope it helps. cheers ;)

Building on @general03's answer, you can use Android's built-in style to customize the dialog quickly. You can find the dialog themes under android.R.style.Theme_DeviceDefault_Dialogxxx.

For example:

builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_Dialog_MinWidth);
builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_Dialog_NoActionBar);
builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_DialogWhenLarge);

It sounds like you want to use join, e.g.:

var text = list.join();

In my deployment I can't use app.config neither to embed what Andrew Webb suggested.
So I'm doing this:

    IWebProxy proxy = WebRequest.GetSystemWebProxy();
    proxy.Credentials = CredentialCache.DefaultCredentials;

    WebClient wc = new WebClient();
    wc.UseDefaultCredentials = true;
    wc.Proxy = proxy;

Just in case you want to check my IE settings:

To cross-correlate 1d arrays use numpy.correlate.

For 2d arrays, use scipy.signal.correlate2d.

There is also scipy.stsci.convolve.correlate2d.

There is also matplotlib.pyplot.xcorr which is based on numpy.correlate.

See this post on the SciPy mailing list for some links to different implementations.

Edit: @user333700 added a link to the SciPy ticket for this issue in a comment.

I'm using Linux Mint 18.2 of this writing. I had a similar issue; when trying to load myphpadmin, it said: "1045 - Access denied for user 'root'@'localhost' (using password: NO)"

I found the file in the /opt/lampp/phpmyadmin directory. I opened the config.inc.php file with my text editor and typed in the correct password. Saved it, and launched it successfully. Profit!

I was having problems with modifying folders and files, I had to change permission to access all my files in /opt/lampp/ directory. I hope this helps someone in the future.

I was running Jenkins executing java -jar jenkins.war.

In my case Jenkins wrote webroot in an stdout: webroot: $user.home/.jenkins. So admin secret key was placed in a ~/.jenkins/secrets/initialAdminPassword.

The problem with your code seems to be the elseif-statement which should be else if (Notice the space).

I rewrote and simplyfied the code to this:

$(document).ready(function () {

    if (screen.width < 1024) {
        $(".yourClass").hide();
    }
    else {

        $(".yourClass").show();
    }

});

Try

expect(new ThrowableMessageMatcher(new StringContains(message)))

instead of

expectMessage(message)

You may write a custom ExpectedException or utility method to wrap up the code.

The regular expression I ended up using for when I want to allow spaces in the middle of my string, but not at the beginning or end was this:

[\S]+(\s[\S]+)*

or

^[\S]+(\s[\S]+)*$

So, I know this is an old question, but you could do something like:

if (/^\s+$/.test(myString)) {
    //string contains characters and white spaces
}

or you can do what nickf said and use:

if (/\S/.test(myString)) {
    // string is not empty and not just whitespace
}

When converting SVG to transparent PNG, don't forget to put this BEFORE $imagick->readImageBlob():

$imagick->setBackgroundColor(new ImagickPixel('transparent'));

Another method without having to update your Python code at all, would be to redirect via the console.

Basically, have your Python script print() as usual, then call the script from the command line and use command line redirection. Like this:

$ python ./myscript.py > output.txt

Your output.txt file will now contain all output from your Python script.

Edit:
To address the comment; for Windows, change the forward-slash to a backslash.
(i.e. .\myscript.py)

If that's what I understood, it's like this:

C:\Users\(username)\AppData\Local\Programs\Python\Python(version)

COPY (not delete) python.exe and rename to py.exe and execute:

py filename.py

1. You could call std::terminate() from any thread and the thread you're referring to will forcefully end.

2. You could arrange for ~thread() to be executed on the object of the target thread, without a intervening join() nor detach() on that object. This will have the same effect as option 1.

3. You could design an exception which has a destructor which throws an exception. And then arrange for the target thread to throw this exception when it is to be forcefully terminated. The tricky part on this one is getting the target thread to throw this exception.

Options 1 and 2 don't leak intra-process resources, but they terminate every thread.

Option 3 will probably leak resources, but is partially cooperative in that the target thread has to agree to throw the exception.

There is no portable way in C++11 (that I'm aware of) to non-cooperatively kill a single thread in a multi-thread program (i.e. without killing all threads). There was no motivation to design such a feature.

A std::thread may have this member function:

native_handle_type native_handle();

You might be able to use this to call an OS-dependent function to do what you want. For example on Apple's OS's, this function exists and native_handle_type is a pthread_t. If you are successful, you are likely to leak resources.

I have one strange problem. In fact when i plug my phone to my mac the time of the device change but not use the actual hour. For example on my computer I have this hour : 05:17 pm but on my phone when is unlocked time is frozen to 09:41 am so when i try to build my app on phone from xCode i have the next error message :

Please verify that your device’s clock is properly set

The strange thing is that when my phone is still pluged to the mac the time on lockScreen is good (05:17 pm)... And if i check on Date & Time on general settings I have this strange thing too (time of statusbar is wrong but time below is good) :

Wrong time on statusBar

After few minutes i understood that it was because of QuickTime Player which was running on my mac with view of my iPhone (i was going to save a video demo of my app).

To resolve the problem I had to quit all applications and restart computer.

In plus at the end if problem persists do these steps :

• xcode: Preferences > Accounts
• Select your apple account
• Remove it
• Add your Apple account (+)
• Run your app again.

Hope this can help.

Thank you,

I know this is a question regarding the CSS.Tooltips library. However, for anyone else came here resulting from google search "tooltip for input box" like I did, here is the simplest way:

<input title="This is the text of the tooltip" value="44"/>

UTC dates don't need any timezone info since they're UTC, which by definition means that they have no offset.

I prefer feature before layers, but I guess it depends on you project. Consider your forces:

• Dependencies
  Try minimize package dependencies, especially between features. Extract APIs if necessary.
• Team organization
  In some organizations teams work on features and in others on layers. This influence how code is organized, use it to formalize APIs or encourage cooperation.
• Deployment and versioning
  Putting everything into a module make deployment and versioning simpler, but bug fixing harder. Splitting things enable better control, scalability and availability.
• Respond to change
  Well organized code is much simpler to change than a big ball of mud.
• Size (people and lines of code)
  The bigger the more formalized/standardized it needs to be.
• Importance/quality
  Some code is more important than other. APIs should be more stable then the implementation. Therefore it needs to be clearly separated.
• Level of abstraction and entry point
  It should be possible for an outsider to know what the code is about, and where to start reading from looking at the package tree.

Example:

com/company/module
  + feature1/
    - MainClass          // The entry point for exploring
    + api/               // Public interface, used by other features
    + domain/
      - AggregateRoot
      + api/             // Internal API, complements the public, used by web
      + impl/ 
    + persistence/       
    + web/               // presentation layer 
    + services/          // Rest or other remote API 
    + support/            
  + feature2/
  + support/             // Any support or utils used by more than on feature
    + io
    + config
    + persistence
    + web

This is just an example. It is quite formal. For example it defines 2 interfaces for feature1. Normally that is not required, but could be a good idea if used differently by different people. You may let the internal API extend the public.

I do not like the 'impl' or 'support' names, but they help separate the less important stuff from the important (domain and API). When it comes to naming I like to be as concrete as possible. If you have a package called 'utils' with 20 classes, move StringUtils to support/string, HttpUtil to support/http and so on.
