bundle install --path vendor/cache

generally fixes it as that is the more common problem. Basically, your bundler path configuration is messed up. See their documentation (first paragraph) for where to find those configurations and change them manually if needed.

If you want to bypass that restriction when fetching the contents with fetch API or XMLHttpRequest in javascript, you can use a proxy server so that it sets the header Access-Control-Allow-Origin to *.

const express = require('express');
const request = require('request');

const app = express();

app.use((req, res, next) => {
  res.header('Access-Control-Allow-Origin', '*');
  next();
});

app.get('/fetch', (req, res) => {
  request(
    { url: req.query.url },
    (error, response, body) => {
      if (error || response.statusCode !== 200) {
        return res.status(500).send('error');
      }
      res.send(body);
    }
  )
});

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => console.log(`listening on ${PORT}`));

Above is a sample code( node Js required ) which can act as a proxy server. For eg: If I want to fetch https://www.google.com normally a CORS error is thrown, but now since the request is sent through the proxy server hosted locally at port 3000, the proxy server adds the Access-Control-Allow-Origin header in the response and there wont be any issue.

Send a GET request to http://localhost:3000/fetch?url=Your URL here , instead of directly sending the request to the URl you want to fetch.

Your URL here stands for the URL you wish to fetch eg: https://www.google.com

I have same problem.

I fixed by android sdk tool version downgrade.

The steps.

1. Delete android sdk "tools" folder : [Your Android SDK root]/tools -> tools

2. Download SDK Tools: http://dl-ssl.google.com/android/repository/tools_r25.2.5-windows.zip

3. Extract that to Android SDK root

4. Build your project

Perfectly fine.
You can't instantiate abstract classes.. but abstract classes can be used to house common implementations for m1() and m3().
So if m2() implementation is different for each implementation but m1 and m3 are not. You could create different concrete IAnything implementations with just the different m2 implementation and derive from AbstractThing -- honoring the DRY principle. Validating if the interface is completely implemented for an abstract class is futile..

Update: Interestingly, I find that C# enforces this as a compile error. You are forced to copy the method signatures and prefix them with 'abstract public' in the abstract base class in this scenario.. (something new everyday:)

Following are the results when we use both [MaxLength] and [StringLength] attributes, in EF code first. If both are used, [MaxLength] wins the race. See the test result in studentname column in below class

 public class Student
 {
    public Student () {}

    [Key]
    [Column(Order=1)]
    public int StudentKey { get; set; }

    //[MaxLength(50),StringLength(60)]    //studentname column will be nvarchar(50)
    //[StringLength(60)]    //studentname column will be nvarchar(60)
    [MaxLength(50)] //studentname column will be nvarchar(50)
    public string StudentName { get; set; }

    [Timestamp]
    public byte[] RowVersion { get; set; }
 }

You can do this all from within your service executable in response to events fired from the InstallUtil process. Override the OnAfterInstall event to use a ServiceController class to start the service.

Although adequate answers have already been given, I'd like to propose a less verbose solution, that can be used without the helper methods available in an MVC controller class. Using a third party library called "RazorEngine" you can use .Net file IO to get the contents of the razor file and call

string html = Razor.Parse(razorViewContentString, modelObject);

Get the third party library here.

How about a pragmatic answer.

Let's go to youtube and run this code

Object.fromEntries(Object.entries([...document.querySelectorAll('[id]')].reduce((s, e) => { s[e.id] = (s[e.id] || 0) + 1; return s; }, {})).filter(([k,v]) => v > 1))

and see all the repeated ids.

Changing the code above to show ids repeated more than 10 times here's the list it produced

additional-metadata-line: 43
avatar: 46
avatar-link: 43
button: 120
buttons: 45
byline-container: 45
channel-name: 44
container: 51
content: 49
details: 43
dismissable: 46
dismissed: 46
dismissed-content: 43
hover-overlays: 45
img: 90
menu: 50
meta: 44
metadata: 44
metadata-line: 43
mouseover-overlay: 45
overlays: 45
repeat: 36
separator: 43
text: 49
text-container: 44
thumbnail: 46
tooltip: 80
top-level-buttons: 45
video-title: 43
video-title-link: 43

Other sites that use the same id more than once include Amazon.com, ebay.com, expedia.com, cnn.com

clearly ids are just another piece of metadata on an element.

getElementById is pretty much obsolete. You can use querySelectorAll for all elements or querySelector for the first, regardless of selector so if you want all elements with id foo then

document.querySelectorAll('#foo')  // returns all elements with id="foo"

where as if you want only the first element use querySelector

document.querySelector('#foo')  // returns the first element with id="foo"
document.querySelector('.foo')  // returns the first element with class "foo"
document.querySelector('foo')   // returns the first <foo> element
document.querySelector('foo .foo #foo') // returns the first element with
                                        // id="foo" that has an ancestor
                                        // with class "foo" who has an
                                        // ancestor <foo> element.

And we can see that using selectors we can find different elements with the same id.

function addClick(selector, add) {
  document.querySelector(selector).addEventListener('click', function() {
    const e = this.parentElement.querySelector('span');
    e.textContent = parseInt(e.textContent) + add;
  });
}
addClick('.e #foo', 1);
addClick('.f #foo', 10);

body { font-size: x-large; font-weight: bold; }
.a #foo { color: red; }
.b #foo { color: green; }
div:nth-child(3) #foo { color: blue; }
#foo { color: purple }

<div class="a"><span id="foo">a</span></div>
<div class="b"><span id="foo">b</span></div>
<div><span id="foo">c</span></div>
<span id="foo">d</span>
<div class="e"><button type="button" id="foo">+1</button>: <span>0</span></div>
<div class="f"><button type="button" id="foo">+10</button>: <span>0</span></div>

Where it matters that id is unique

• <a> tags can reference ids as in <a href="#foo">. Clicking it will jump the document to the first element with id="foo". Similarly the hash tag in the URL which is effectively the same feature.

• <label> tags have a for attribute that specifies which element they are labeling by id. Clicking the label clicks/activates/give-the-focus-to the corresponding element. The label will only affect the first element with a matching id

label { user-select: none; }

<p>nested for checking</p>
<form>
  <div><input type="checkbox" id="foo"><label for="foo">foo</label></div>
</form>
<form>
  <div><input type="checkbox" id="foo"><label for="foo">foo (clicking here will check first checkbox)</label></div>
</form>

Otherwise, id is just another tool in your toolbox.

If you pass a String argument it will count the repetition of each word

/**
 * @param string
 * @return map which contain the word and value as the no of repatation
 */
public Map findDuplicateString(String str) {
    String[] stringArrays = str.split(" ");
    Map<String, Integer> map = new HashMap<String, Integer>();
    Set<String> words = new HashSet<String>(Arrays.asList(stringArrays));
    int count = 0;
    for (String word : words) {
        for (String temp : stringArrays) {
            if (word.equals(temp)) {
                ++count;
            }
        }
        map.put(word, count);
        count = 0;
    }

    return map;

}

output:

 Word1=2, word2=4, word2=1,. . .

yum uses RPM, so the following command will list the contents of the installed package:

$ rpm -ql package-name

You can use the % operator to find the remainder of a division, and compare the result with 0.

Example:

if (number % divisor == 0)
{
    //code for perfect divisor
}
else
{
    //the number doesn't divide perfectly by divisor
}

This implementation wrap entity exception to exception with detail text. It handles DbEntityValidationException, DbUpdateException, datetime2 range errors (MS SQL), and include key of invalid entity in message (useful when savind many entities at one SaveChanges call).

First, override SaveChanges in DbContext class:

public class AppDbContext : DbContext
{
    public override int SaveChanges()
    {
        try
        {
            return base.SaveChanges();
        }
        catch (DbEntityValidationException dbEntityValidationException)
        {
            throw ExceptionHelper.CreateFromEntityValidation(dbEntityValidationException);
        }
        catch (DbUpdateException dbUpdateException)
        {
            throw ExceptionHelper.CreateFromDbUpdateException(dbUpdateException);
        }
    }   

    public override async Task<int> SaveChangesAsync(CancellationToken cancellationToken)
    {
        try
        {
            return await base.SaveChangesAsync(cancellationToken);
        }
        catch (DbEntityValidationException dbEntityValidationException)
        {
            throw ExceptionHelper.CreateFromEntityValidation(dbEntityValidationException);
        }
        catch (DbUpdateException dbUpdateException)
        {
            throw ExceptionHelper.CreateFromDbUpdateException(dbUpdateException);
        }
    }

ExceptionHelper class:

public class ExceptionHelper
{
    public static Exception CreateFromEntityValidation(DbEntityValidationException ex)
    {
        return new Exception(GetDbEntityValidationMessage(ex), ex);
    }

    public static string GetDbEntityValidationMessage(DbEntityValidationException ex)
    {
        // Retrieve the error messages as a list of strings.
        var errorMessages = ex.EntityValidationErrors
            .SelectMany(x => x.ValidationErrors)
            .Select(x => x.ErrorMessage);

        // Join the list to a single string.
        var fullErrorMessage = string.Join("; ", errorMessages);

        // Combine the original exception message with the new one.
        var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);
        return exceptionMessage;
    }

    public static IEnumerable<Exception> GetInners(Exception ex)
    {
        for (Exception e = ex; e != null; e = e.InnerException)
            yield return e;
    }

    public static Exception CreateFromDbUpdateException(DbUpdateException dbUpdateException)
    {
        var inner = GetInners(dbUpdateException).Last();
        string message = "";
        int i = 1;
        foreach (var entry in dbUpdateException.Entries)
        {
            var entry1 = entry;
            var obj = entry1.CurrentValues.ToObject();
            var type = obj.GetType();
            var propertyNames = entry1.CurrentValues.PropertyNames.Where(x => inner.Message.Contains(x)).ToList();
            // check MS SQL datetime2 error
            if (inner.Message.Contains("datetime2"))
            {
                var propertyNames2 = from x in type.GetProperties()
                                        where x.PropertyType == typeof(DateTime) ||
                                            x.PropertyType == typeof(DateTime?)
                                        select x.Name;
                propertyNames.AddRange(propertyNames2);
            }

            message += "Entry " + i++ + " " + type.Name + ": " + string.Join("; ", propertyNames.Select(x =>
                string.Format("'{0}' = '{1}'", x, entry1.CurrentValues[x])));
        }
        return new Exception(message, dbUpdateException);
    }
}

Bootstrap 3

Here are the selectors used in BS3, if you want to stay consistent:

@media(max-width:767px){}
@media(min-width:768px){}
@media(min-width:992px){}
@media(min-width:1200px){}

Note: FYI, this may be useful for debugging:

<span class="visible-xs">SIZE XS</span>
<span class="visible-sm">SIZE SM</span>
<span class="visible-md">SIZE MD</span>
<span class="visible-lg">SIZE LG</span>

Bootstrap 4

Here are the selectors used in BS4. There is no "lowest" setting in BS4 because "extra small" is the default. I.e. you would first code the XS size and then have these media overrides afterwards.

@media(min-width:576px){}
@media(min-width:768px){}
@media(min-width:992px){}
@media(min-width:1200px){}

Update 2019-02-11: BS3 info is still accurate as of version 3.4.0, updated BS4 for new grid, accurate as of 4.3.0.

Try it:

img {
  pointer-events: none;
}

and try to avoid

* {
  pointer-events: none;
}

I think the following code is more pythonic:

from hashlib import md5

def get_md5(fname):
    m = md5()
    with open(fname, 'rb') as fp:
        for chunk in fp:
            m.update(chunk)
    return m.hexdigest()

Yes, both use deferred execution. Let's illustrate the difference using the SQL Server profiler....

When we run the following code:

MarketDevEntities db = new MarketDevEntities();

IEnumerable<WebLog> first = db.WebLogs;
var second = first.Where(c => c.DurationSeconds > 10);
var third = second.Where(c => c.WebLogID > 100);
var result = third.Where(c => c.EmailAddress.Length > 11);

Console.Write(result.First().UserName);

In SQL Server profiler we find a command equal to:

"SELECT * FROM [dbo].[WebLog]"

It approximately takes 90 seconds to run that block of code against a WebLog table which has 1 million records.

So, all table records are loaded into memory as objects, and then with each .Where() it will be another filter in memory against these objects.

When we use IQueryable instead of IEnumerable in the above example (second line):

In SQL Server profiler we find a command equal to:

"SELECT TOP 1 * FROM [dbo].[WebLog] WHERE [DurationSeconds] > 10 AND [WebLogID] > 100 AND LEN([EmailAddress]) > 11"

It approximately takes four seconds to run this block of code using IQueryable.

IQueryable has a property called Expression which stores a tree expression which starts being created when we used the result in our example (which is called deferred execution), and at the end this expression will be converted to an SQL query to run on the database engine.

git reset --hard origin/master

will remove all commits not in origin/master where origin is the repo name and master is the name of the branch.

See if the following syntax suits you:

// WeekEnd enumeration
enum WeekEnd
{
    Sunday = 1,
    Saturday = 7
};

// String support for WeekEnd
Begin_Enum_String( WeekEnd )
{
    Enum_String( Sunday );
    Enum_String( Saturday );
}
End_Enum_String;

// Convert from WeekEnd to string
const std::string &str = EnumString<WeekEnd>::From( Saturday );
// str should now be "Saturday"

// Convert from string to WeekEnd
WeekEnd w;
EnumString<WeekEnd>::To( w, "Sunday" );
// w should now be Sunday

If it does, then you might want to check out this article:
http://www.gamedev.net/reference/snippets/features/cppstringizing/

There are several things wrong with this as you can see in the other posts, but the reason you're getting that error is because you name your form getElementById. So document.getElementById now points to your form instead of the default method that javascript provides. See my fiddle for a working demo https://jsfiddle.net/jemartin80/nhjehwqk/.

function checkValues()
{
   var isFormValid, form_fname;

   isFormValid = true;
   form_fname = document.getElementById("fname");
   if (form_fname.value === "")
   {
       isFormValid = false;
   }
   isFormValid || alert("I am indicating that there is something wrong with your input.")

   return isFormValid;
}

Use an AppDomain

It is safer and more flexible to load the assembly into its own AppDomain first.

So instead of the answer given previously:

var asm = Assembly.LoadFile(@"C:\myDll.dll");
var type = asm.GetType("TestRunner");
var runnable = Activator.CreateInstance(type) as IRunnable;
if (runnable == null) throw new Exception("broke");
runnable.Run();

I would suggest the following (adapted from this answer to a related question):

var domain = AppDomain.CreateDomain("NewDomainName");
var t = typeof(TypeIWantToLoad);
var runnable = domain.CreateInstanceFromAndUnwrap(@"C:\myDll.dll", t.Name) as IRunnable;
if (runnable == null) throw new Exception("broke");
runnable.Run();

Now you can unload the assembly and have different security settings.

If you want even more flexibility and power for dynamic loading and unloading of assemblies, you should look at the Managed Add-ins Framework (i.e. the System.AddIn namespace). For more information, see this article on Add-ins and Extensibility on MSDN.

No you cannot. The only thing you can do is to insert content. Like so:

p:after {
    content: "yo";
}

The key difference in a nutshell is that reset moves the current branch reference, while checkout does not (it moves HEAD).

As the Pro Git book explains under Reset Demystified,

The first thing reset will do is move what HEAD points to. This isn’t the same as changing HEAD itself (which is what checkout does); reset moves the branch that HEAD is pointing to. This means if HEAD is set to the master branch (i.e. you’re currently on the master branch), running git reset 9e5e6a4 will start by making master point to 9e5e6a4. [emphasis added]

See also VonC's answer for a very helpful text and diagram excerpt from the same article, which I won't duplicate here.

Of course there are a lot more details about what effects checkout and reset can have on the index and the working tree, depending on what parameters are used. There can be lots of similarities and differences between the two commands. But as I see it, the most crucial difference is whether they move the tip of the current branch.

append: Appends object at the end.

x = [1, 2, 3]
x.append([4, 5])
print (x)

gives you: [1, 2, 3, [4, 5]]

extend: Extends list by appending elements from the iterable.

x = [1, 2, 3]
x.extend([4, 5])
print (x)

gives you: [1, 2, 3, 4, 5]

This will change your current working directory to so that opening relative paths will work:

import os
os.chdir("/home/udi/foo")

However, you asked how to change into whatever directory your Python script is located, even if you don't know what directory that will be when you're writing your script. To do this, you can use the os.path functions:

import os

abspath = os.path.abspath(__file__)
dname = os.path.dirname(abspath)
os.chdir(dname)

This takes the filename of your script, converts it to an absolute path, then extracts the directory of that path, then changes into that directory.

Simply add an extension to the -i flag. This basically creates a backup file with the original file.

sed -i.bakup 's/linenumber/number/' ~/.vimrc

sed will execute without the error

Not quite, the AND has to be lower-case.

<xsl:when test="4 &lt; 5 and 1 &lt; 2">
<!-- do something -->
</xsl:when>

I've had the same problem with you.

cd to ../etc/ then use ls to make sure your "paths" file is in , vim paths, add "/usr/local/bin" at the end of the file.

django-admin --version
python manage.py --version
pip freeze | grep django

You could also take a look at the DatePeriod class:

$period = new DatePeriod(
     new DateTime('2010-10-01'),
     new DateInterval('P1D'),
     new DateTime('2010-10-05')
);

Which should get you an array with DateTime objects.

To iterate

foreach ($period as $key => $value) {
    //$value->format('Y-m-d')       
}

On a Mac, before doing all the hard work, simply check your settings in System Preferences > MySQL. More often than not, I've experienced the team running into this problem since The MySQL Server Instance is stopped.

Click the Start MySQL Server button, and magic will happen.

If you are using freezegun package in tests you may need to have more smart isinstance checks which works well with FakeDate and original Date/Datetime beeing inside with freeze_time context:

def isinstance_date(value):
    """Safe replacement for isinstance date which works smoothly also with Mocked freezetime"""
    import datetime
    if isinstance(value, datetime.date) and not isinstance(value, datetime.datetime):
        return True
    elif type(datetime.datetime.today().date()) == type(value):
        return True
    else:
        return False


def isinstance_datetime(value):
    """Safe replacement for isinstance datetime which works smoothly also with Mocked freezetime """
    import datetime
    if isinstance(value, datetime.datetime):
        return True
    elif type(datetime.datetime.now()) == type(value):
        return True
    else:
        return False

and tests to verify the implementation

class TestDateUtils(TestCase):

    def setUp(self):
        self.date_orig = datetime.date(2000, 10, 10)
        self.datetime_orig = datetime.datetime(2000, 10, 10)

        with freeze_time('2001-01-01'):
            self.date_freezed = datetime.date(2002, 10, 10)
            self.datetime_freezed = datetime.datetime(2002, 10, 10)

    def test_isinstance_date(self):
        def check():
            self.assertTrue(isinstance_date(self.date_orig))
            self.assertTrue(isinstance_date(self.date_freezed))
            self.assertFalse(isinstance_date(self.datetime_orig))
            self.assertFalse(isinstance_date(self.datetime_freezed))
            self.assertFalse(isinstance_date(None))

        check()
        with freeze_time('2005-01-01'):
            check()

    def test_isinstance_datetime(self):
        def check():
            self.assertFalse(isinstance_datetime(self.date_orig))
            self.assertFalse(isinstance_datetime(self.date_freezed))
            self.assertTrue(isinstance_datetime(self.datetime_orig))
            self.assertTrue(isinstance_datetime(self.datetime_freezed))
            self.assertFalse(isinstance_datetime(None))

        check()
        with freeze_time('2005-01-01'):
            check()

You need Optional.isPresent() and orElse(). Your snippet won;t work because it doesn't return anything if not present.

The point of Optional is to return it from the method.

Alternatively, with MTCNN and OpenCV(other dependencies including TensorFlow also required), you can:

1 Perform face detection(Input an image, output all boxes of detected faces):

from mtcnn.mtcnn import MTCNN
import cv2

face_detector = MTCNN()

img = cv2.imread("Anthony_Hopkins_0001.jpg")
detect_boxes = face_detector.detect_faces(img)
print(detect_boxes)

[{'box': [73, 69, 98, 123], 'confidence': 0.9996458292007446, 'keypoints': {'left_eye': (102, 116), 'right_eye': (150, 114), 'nose': (129, 142), 'mouth_left': (112, 168), 'mouth_right': (146, 167)}}]

2 save all detected faces to separate files:

for i in range(len(detect_boxes)):
    box = detect_boxes[i]["box"]
    face_img = img[box[1]:(box[1] + box[3]), box[0]:(box[0] + box[2])]
    cv2.imwrite("face-{:03d}.jpg".format(i+1), face_img)

3 or Draw rectangles of all detected faces:

for box in detect_boxes:
    box = box["box"]
    pt1 = (box[0], box[1]) # top left
    pt2 = (box[0] + box[2], box[1] + box[3]) # bottom right
    cv2.rectangle(img, pt1, pt2, (0,255,0), 2)
cv2.imwrite("detected-boxes.jpg", img)

As a supplementary, on Amazon EC2, what I need to do is:

sudo yum install freetype-devel
sudo yum install libpng-devel
sudo pip install matplotlib

Adding to the above answers, I put the following lines in my .bash_profile (or .zshrc for MacOS 10.15+) which makes it really convenient to switch (including @elektromin's comment for java 9):

alias j12="export JAVA_HOME=`/usr/libexec/java_home -v 12`; java -version"
alias j11="export JAVA_HOME=`/usr/libexec/java_home -v 11`; java -version"
alias j10="export JAVA_HOME=`/usr/libexec/java_home -v 10`; java -version"
alias j9="export JAVA_HOME=`/usr/libexec/java_home -v 9`; java -version"
alias j8="export JAVA_HOME=`/usr/libexec/java_home -v 1.8`; java -version"
alias j7="export JAVA_HOME=`/usr/libexec/java_home -v 1.7`; java -version"

After inserting, execute $ source .bash_profile

I can switch to Java 8 by typing the following:

$ j8
java version "1.8.0_102"
Java(TM) SE Runtime Environment (build 1.8.0_102-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode)

Logging options are provider-specific. You need to know which JPA implementation do you use.

• Hibernate (see here):

  <property name = "hibernate.show_sql" value = "true" />
  

• EclipseLink (see here):

  <property name="eclipselink.logging.level" value="FINE"/>
  

• OpenJPA (see here):

  <property name="openjpa.Log" value="DefaultLevel=WARN,Runtime=INFO,Tool=INFO,SQL=TRACE"/>
  

• DataNucleus (see here):

  Set the log category DataNucleus.Datastore.Native to a level, like DEBUG.

I'm assuming your column is 38 characters in length, so you want to truncate itemdescription to fit within the database. A utility function like the following should do what you want:

/**
 * Truncates s to fit within len. If s is null, null is returned.
 **/
public String truncate(String s, int len) { 
  if (s == null) return null;
  return s.substring(0, Math.min(len, s.length()));
}

then you just call it like so:

String value = "_";
if (itemdescription != null && itemdescription.length() > 0) {
  value = truncate(itemdescription, 38);
}

pstmt2.setString(3, value);

Here is some code I wrote to help us identify and correct untrusted CONSTRAINTs in a DATABASE. It generates the code to fix each issue.

    ;WITH Untrusted (ConstraintType, ConstraintName, ConstraintTable, ParentTable, IsDisabled, IsNotForReplication, IsNotTrusted, RowIndex) AS

        , fk.is_not_trusted
        , ROW_NUMBER() OVER (ORDER BY OBJECT_NAME( fk.parent_object_id), OBJECT_NAME( fk.referenced_object_id), fk.name) AS RowIndex
    FROM 
        sys.foreign_keys fk 
    WHERE 
        is_ms_shipped = 0 
        AND fk.is_not_trusted = 1       

    UNION ALL

        AND cc.is_not_trusted = 1

)

If the format is guaranteed to be correct YYYY/MM/DD and exactly the same between the two fields then you can use:

if (startdate > enddate) {
   alert('error'
}

As a string comparison

Without JQuery

String.prototype.ucwords = function() {
    str = this.trim();
    return str.replace(/(^([a-zA-Z\p{M}]))|([ -][a-zA-Z\p{M}])/g, function(s){
        return s.toUpperCase();
    });
};

console.log('hello world'.ucwords()); // Display Hello World

Yes:

<input required title="Enter something OR ELSE." /> 

The title attribute will be used to notify the user of a problem.

Expires and Cache-Control are "strong caching headers"

Last-Modified and ETag are "weak caching headers"

First the browser check Expires/Cache-Control to determine whether or not to make a request to the server

If have to make a request, it will send Last-Modified/ETag in the HTTP request. If the Etag value of the document matches that, the server will send a 304 code instead of 200, and no content. The browser will load the contents from its cache.

Thanks for this. You can change the hover icon by assigning a CSS class to the row like:

<tr class="pointer" onclick="document.location = 'links.html';">

and the CSS looks like:

<style>
    .pointer { cursor: pointer; }
</style>

If you do not need a table border, apply this:

table{
    table-layout:fixed;
    border-collapse:collapse;
}
td{
    word-wrap: break-word;
}

How about something like:

gem dependency devise --pipe | cut -d \  -f 1 | xargs gem uninstall -a

(this assumes that you're not using bundler - but I guess you're not since removing from your bundle gemspec would solve the problem)

I had a similar problem and solved it using list...not sure if this will help or not

classes = list(unique_labels(y_true, y_pred))

if ( $('#whatever')[0] ) {...}

The jQuery object which is returned by all native jQuery methods is NOT an array, it is an object with many properties; one of them being a "length" property. You can also check for size() or get(0) or get() - 'get(0)' works the same as accessing the first element, i.e. $(elem)[0]

For macOS in 2018+ (as ALL of the solutions above are failing for me):

Simply go to the official nodejs site, download the official nodejs package and install it by double clicking. It's the most simple, safe and always-working thing you can do.

This won't do what you are expecting:

<img src="image1.gif" alt="image2.gif" />

The ALT attribute is text-only--it won't do anything special if you give it an image URL.

If you want to initially display a low res image, then replace it with a high res image, you could do some javascript coding to swap out the images. Or, perhaps load the image into a div which has a background pattern filled with the low res image. Then, when the high res image loads, it'll load overtop the background.

Unfortunately, there's no direct way to do this.

Your second attempt will create a link to image2, but actually display image1.

<a href="image2.gif" ><img src="image1.gif"/></a>

If you want to popup a higher res version, @Sam's suggestion is a good idea.

This CSS might work for you (it works for me in Firefox 3):

<html>
<head>
    <style>
        .lowres { background-image: url('low-res.png');}
    </style>
</head>
<body>
    <div class="lowres" style="height:500px; width:500px">
        <img src="hi-res.png" />
    </div>
</body>
</html>

In that example, you have to set the div height/width to that of the image. It will actually load both images simultaneously, but presuming the low-res one loads quick, you might see it first while the hi-res image downloads.

You have to add the order direction right after the column name:

$qb->orderBy('column1 ASC, column2 DESC');

As you have noted, multiple calls to orderBy do not stack, but you can make multiple calls to addOrderBy:

$qb->addOrderBy('column1', 'ASC')
   ->addOrderBy('column2', 'DESC');

I got a bad result with git push origin branch1:branch2 command:

In my case, branch2 is deleted and branch1 has been updated with some new changes.

Hence, if you want only the changes push on the branch2 from the branch1, try procedures below:

• On branch1: git add .
• On branch1: git commit -m 'comments'

• On branch1: git push origin branch1

• On branch2: git pull origin branch1

• On branch1: revert to the previous commit.

This is what finally worked for me:

So far as my observation goes, any answer posted here can have unexpected side effects.

In ES2015-compatible enviroment, you can avoid any side effects by using WeakMap.

const id = (() => {
    let currentId = 0;
    const map = new WeakMap();

    return (object) => {
        if (!map.has(object)) {
            map.set(object, ++currentId);
        }

        return map.get(object);
    };
})();

id({}); //=> 1

The file is a german file (Arbeitsblätter = worksheets). The table names (Tabelle3 etc) are in the correct order. You just need to read these tags;)

I posted that in jQuery forums (I hope it can help):

Diving into the jQM code i've found this solution. I hope it can help other people:

To refresh a dynamically modified page:

function refreshPage(page){
    // Page refresh
    page.trigger('pagecreate');
    page.listview('refresh');
}

It works even if you create new headers, navbars or footers. I've tested it with jQM 1.0.1.

select user_name
from my_table
where nlssort(user_name, 'NLS_SORT = Latin_CI') = nlssort('%AbC%', 'NLS_SORT = Latin_CI')

this is pretty simple:

HttpUtility.HtmlDecode(Model.Content)

Another Solution, you could also return a HTMLString, Razor will output the correct formatting:

in the view itself:

@Html.GetSomeHtml()

in controller:

public static HtmlString GetSomeHtml()
{
    var Data = "abc<br/>123";
    return new HtmlString(Data);
}

Just as reference, you can also use Mysql Variables to save temporary results, e.g.:

SET @v1 := (SELECT ... );
UPDATE ... SET ... WHERE x=@v1;

This solution worked very well for me, i'm doing this in a directive:

scope.$watch(attrs.testWatch, function() {.....}, true);

the true works pretty well and react for all the chnages (add, delete, or modify a field).

Here is a working plunker for play with it.

Deeply Watching an Array in AngularJS

I hope this can be useful for you. If you have any questions, feel free for ask, I'll try to help :)

Using leech's answer with indexOf (to support IE)

This is using what leech talked about, but making it work for IE (IE doesn't support matches):

function closest(el, selector, stopSelector) {
  var retval = null;
  while (el) {
    if (el.className.indexOf(selector) > -1) {
      retval = el;
      break
    } else if (stopSelector && el.className.indexOf(stopSelector) > -1) {
      break
    }
    el = el.parentElement;
  }
  return retval;
}

It's not perfect, but it works if the selector is unique enough so it won't accidentally match the incorrect element.

foreach is almost equivalent to :

var enumerator = list.GetEnumerator();
var element;
while(enumerator.MoveNext()){
  element = enumerator.Current;
}

and in order to implemetn a "foreach" compliant pattern, this need to provide a class that have a method GetEnumerator() which returns an object that have a MoveNext() method, a Reset() method and a Current property.

Indeed, you do not need to implement neither IEnumerable nor IEnumerator.

Some derived points:

• foreach does not need to know the collection length so allows to iterate through a "stream" or a kind of "elements producer".
• foreach calls virtual methods on the iterator (the most of the time) so can perform less well than for.

Most basic regex is following:

(^([0-9A-Fa-f]{8}[-][0-9A-Fa-f]{4}[-][0-9A-Fa-f]{4}[-][0-9A-Fa-f]{4}[-][0-9A-Fa-f]{12})$) 

or you could paste it here.

Hope this saves you some time.

1. Open the file using vi myfile.csv
2. Press Escape
3. Type :%s/replaceme/withthis/
4. Type :wq and press Enter

Now you will have the new pattern in your file.

The first example demonstrates event delegation. The event handler is bound to an element higher up the DOM tree (in this case, the document) and will be executed when an event reaches that element having originated on an element matching the selector.

This is possible because most DOM events bubble up the tree from the point of origin. If you click on the #id element, a click event is generated that will bubble up through all of the ancestor elements (side note: there is actually a phase before this, called the 'capture phase', when the event comes down the tree to the target). You can capture the event on any of those ancestors.

The second example binds the event handler directly to the element. The event will still bubble (unless you prevent that in the handler) but since the handler is bound to the target, you won't see the effects of this process.

By delegating an event handler, you can ensure it is executed for elements that did not exist in the DOM at the time of binding. If your #id element was created after your second example, your handler would never execute. By binding to an element that you know is definitely in the DOM at the time of execution, you ensure that your handler will actually be attached to something and can be executed as appropriate later on.

With the Material Components library you can use the CircularProgressIndicator:

Something like:

<com.google.android.material.progressindicator.CircularProgressIndicator
      android:indeterminate="true"          
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      app:indicatorColor="@array/progress_colors"
      app:indicatorSize="xxdp"
      app:showAnimationBehavior="inward"/>

where array/progress_colors is an array with the colors:

  <integer-array name="progress_colors">
    <item>@color/yellow_500</item>
    <item>@color/blue_700</item>
    <item>@color/red_500</item>
  </integer-array>

Note: it requires at least the version 1.3.0

use .load to load your image. to test if you get an error ( let's say 404 ) you can do the following:

$("#img_id").error(function(){
  //$(this).hide();
  //alert("img not loaded");
  //some action you whant here
});

careful - .error() event will not trigger when the src attribute is empty for an image.

If you are the owner it is simple:

• Go to your repo and click the Settings button.
• In the left menu click Collaborators
• Then Add their name.

Then collaborator should visit this example repo link https://github.com/user/repo/invitations

Here is what we are using at http://www.develop.com/webcasts to keep people from accidentally leaving the page while a video is playing or paused.

$(document).ready(function() {

    var video = $("video#webcast_video");
    if (video.length <= 0) {
        return;
    }

    window.onbeforeunload = function () {
        var htmlVideo = video[0];
        if (htmlVideo.currentTime < 0.01 || htmlVideo.ended) {
            return null;
        }

        return "Leaving this page will stop your video.";
    };
}

You can try something like this..

CREATE TABLE 'sample'.'picture' ( 
'idpicture' INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, 
'caption' VARCHAR(45) NOT NULL, 
'img' LONGBLOB NOT NULL, 
 PRIMARY KEY('idpicture')) TYPE = InnoDB;

Strings are compared lexicographically using the numeric equivalents (the result of the built-in function ord()) of their characters. Unicode and 8-bit strings are fully interoperable in this behavior.

If you want two objects with the same elements but in a different order to compare equal, then the obvious thing to do is compare sorted copies of them - for instance, for the dictionaries represented by your JSON strings a and b:

import json

a = json.loads("""
{
    "errors": [
        {"error": "invalid", "field": "email"},
        {"error": "required", "field": "name"}
    ],
    "success": false
}
""")

b = json.loads("""
{
    "success": false,
    "errors": [
        {"error": "required", "field": "name"},
        {"error": "invalid", "field": "email"}
    ]
}
""")

>>> sorted(a.items()) == sorted(b.items())
False

... but that doesn't work, because in each case, the "errors" item of the top-level dict is a list with the same elements in a different order, and sorted() doesn't try to sort anything except the "top" level of an iterable.

To fix that, we can define an ordered function which will recursively sort any lists it finds (and convert dictionaries to lists of (key, value) pairs so that they're orderable):

def ordered(obj):
    if isinstance(obj, dict):
        return sorted((k, ordered(v)) for k, v in obj.items())
    if isinstance(obj, list):
        return sorted(ordered(x) for x in obj)
    else:
        return obj

If we apply this function to a and b, the results compare equal:

>>> ordered(a) == ordered(b)
True

Assuming you have HTML like this:

<div id='thediv'></div>

If you want to modify the style attribute of this div, you'd use

document.getElementById('thediv').style.[ATTRIBUTE] = '[VALUE]'

Replace [ATTRIBUTE] with the style attribute you want. Remember to remove '-' and make the following letter uppercase.

Examples

document.getElementById('thediv').style.display = 'none'; //changes the display
document.getElementById('thediv').style.paddingLeft = 'none'; //removes padding

Sometimes this happens because symlinks are not allowed in template settings: Advanced > Developer > Template Settings > Allow Symlinks

find_elements_by_xpath("//*[@class='class name']")

is a great solution

just in case you are on Unix, you can use time to get the execution time:

$ g++ myprog.cpp -o myprog
$ time ./myprog

If you've installed 32-bit Office on a 64-bit machine, you may need to check for the presence of "SOFTWARE\Wow6432Node\Microsoft\Office\12.0\", substituting the 12.0 with the appropriate version. This is certainly the case for Office 2007 installed on 64-bit Windows 7.

Note that Office 2010 (== 14.0) is the first Office for which a 64-bit version exists.

var lastname = "Hi";

if(typeof lastname !== "undefined")
{
  alert("Hi. Variable is defined.");
} 

import 'core-js/es7/array' 

into polyfill.ts worked for me.

The fact that the sort values in the OP are integers isn't relevant to the question per se. In other words, the accepted answer would work if the sort value was text. I bring this up to also point out that the sort can be modified during the sort (for example, to account for upper and lower case).

>>> sorted([(121, 'abc'), (231, 'def'), (148, 'ABC'), (221, 'DEF')], key=lambda x: x[1])
[(148, 'ABC'), (221, 'DEF'), (121, 'abc'), (231, 'def')]
>>> sorted([(121, 'abc'), (231, 'def'), (148, 'ABC'), (221, 'DEF')], key=lambda x: str.lower(x[1]))
[(121, 'abc'), (148, 'ABC'), (231, 'def'), (221, 'DEF')]

I found jszip quite useful. I've used so far only for reading, but they have create/edit capabilities as well.

Code wise it looks something like this

var new_zip = new JSZip();
new_zip.load(file);
new_zip.files["doc.xml"].asText() // this give you the text in the file

One thing I noticed is that it seems the file has to be in binary stream format (read using the .readAsArrayBuffer of FileReader(), otherwise I was getting errors saying I might have a corrupt zip file

Edit: Note from the 2.x to 3.0.0 upgrade guide:

The load() method and the constructor with data (new JSZip(data)) have been replaced by loadAsync().

You can read a group of txt files in a folder and echo the contents like this.

 <?php
$directory = "folder/";
$dir = opendir($directory);
$filenames = [];
while (($file = readdir($dir)) !== false) {
$filename = $directory . $file;
$type = filetype($filename);
if($type !== 'file') continue;
$filenames[] = $filename;
}
closedir($dir);
?>

The Excel number for a modern date is most easily calculated as the number of days since 12/30/1899 on the Gregorian calendar.

Excel treats the mythical date 01/00/1900 (i.e., 12/31/1899) as corresponding to 0, and incorrectly treats year 1900 as a leap year. So for dates before 03/01/1900, the Excel number is effectively the number of days after 12/31/1899.

However, Excel will not format any number below 0 (-1 gives you ##########) and so this only matters for "01/00/1900" to 02/28/1900, making it easier to just use the 12/30/1899 date as a base.

A complete function in DB2 SQL that accounts for the leap year 1900 error:

SELECT
   DAYS(INPUT_DATE)                 
   - DAYS(DATE('1899-12-30'))
   - CASE                       
        WHEN INPUT_DATE < DATE('1900-03-01')  
           THEN 1               
           ELSE 0               
     END

In my case, I had a collection of radio buttons that needed to be in a group. I just included a 'Selected' property in the model. Then, in the loop to output the radiobuttons just do...

@Html.RadioButtonFor(m => Model.Selected, Model.Categories[i].Title)

This way, the name is the same for all radio buttons. When the form is posted, the 'Selected' property is equal to the category title (or id or whatever) and this can be used to update the binding on the relevant radiobutton, like this...

model.Categories.Find(m => m.Title.Equals(model.Selected)).Selected = true;

May not be the best way, but it does work.

In new Smarty it is:

<pre>
{var_dump($variable)}
</pre>

In some tests here, it worked perfectly this way:

Decimal.Round(value, 2);

Hope this helps

Try:

var objDate = new Date("10/11/2009");

var strDate =
    objDate.toLocaleString("en", { day: "numeric" }) + ' ' +
    objDate.toLocaleString("en", { month: "long"  }) + ' ' +
    objDate.toLocaleString("en", { year: "numeric"});

You could try the same address with HTTP instead of HTTPS. Be aware that this does use HTTP instead of HTTPS and only some sites might support this method.

Example address: https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

wget http://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

*notice the http:// instead of https://.

This is probably not recommended though :)

If you can, try use curl.

EDIT:

FYI an example with username (and prompt for password) would be:

curl --user $USERNAME -O http://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

Where -O is

 -O, --remote-name
              Write output to a local file named like the remote file we get. (Only the file part of the remote file is used, the path is cut off.)

You can create a custom alertDialog and use a xml layout. in the layout, you can set the background color and textcolor.

Something like this:

Dialog dialog = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar);
LayoutInflater inflater = (LayoutInflater)ActivityName.this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_layout,(ViewGroup)findViewById(R.id.layout_root));
dialog.setContentView(view);

Extract zip file and put the relevant jar file ("mail.jar") in the classpath

As you said, there are many duplicate questions on the same topic. Any how explaining your situation.

The problem might be solved by adding a timeout to call your index.html

ie you need to add super.setIntegerProperty("loadUrlTimeoutValue", 70000); in your activity.java file ( inside src/com/yourProj/--/youractivity.java) above this line: super.loadUrl("file:///android_asset/www/index.html");

Explanation:

This can be happened due to the following reasons

The core reason: the problem is likely due to the speed of the emulator so the network is too slow complete the communication in a timely fashion.

This can be due to:

1. Your code/data/image is of too much of size ( I guess in your case you are using some images ,as you said you made some UI modifications, may be the size of images are high)
2. Your script may have a infinite or long loop, so that it takes too much of time to load.
3. You will be using too much of scripts (jQuery, iscroll, etc etc.. more number of plugins or scripts )

I think the best practice is to have single primary constructor to which the overloaded constructors refer to by calling this() with the relevant parameter defaults. The reason for this is that it makes it much clearer what is the constructed state of the object is - really you can think of the primary constructor as the only real constructor, the others just delegate to it

One example of this might be JTable - the primary constructor takes a TableModel (plus column and selection models) and the other constructors call this primary constructor.

For subclasses where the superclass already has overloaded constructors, I would tend to assume that it is reasonable to treat any of the parent class's constructors as primary and think it is perfectly legitimate not to have a single primary constructor. For example,when extending Exception, I often provide 3 constructors, one taking just a String message, one taking a Throwable cause and the other taking both. Each of these constructors calls super directly.

Three options for you:

1. Using just JavaScript's Date object (no libraries):

My previous answer for #1 was wrong (it added 24 hours, failing to account for transitions to and from daylight saving time; Clever Human pointed out that it would fail with November 7, 2010 in the Eastern timezone). Instead, Jigar's answer is the correct way to do this without a library:

var tomorrow = new Date();
tomorrow.setDate(tomorrow.getDate() + 1);

This works even for the last day of a month (or year), because the JavaScript date object is smart about rollover:

var lastDayOf2015 = new Date(2015, 11, 31);_x000D_
snippet.log("Last day of 2015: " + lastDayOf2015.toISOString());_x000D_
var nextDay = new Date(+lastDayOf2015);_x000D_
var dateValue = nextDay.getDate() + 1;_x000D_
snippet.log("Setting the 'date' part to " + dateValue);_x000D_
nextDay.setDate(dateValue);_x000D_
snippet.log("Resulting date: " + nextDay.toISOString());

<!-- Script provides the `snippet` object, see http://meta.stackexchange.com/a/242144/134069 -->_x000D_
<script src="//tjcrowder.github.io/simple-snippets-console/snippet.js"></script>

(This answer is currently accepted, so I can't delete it. Before it was accepted I suggested to the OP they accept Jigar's, but perhaps they accepted this one for items #2 or #3 on the list.)

2. Using MomentJS:

var today = moment();
var tomorrow = moment(today).add(1, 'days');

(Beware that add modifies the instance you call it on, rather than returning a new instance, so today.add(1, 'days') would modify today. That's why we start with a cloning op on var tomorrow = ....)

3. Using DateJS, but it hasn't been updated in a long time:

var today = new Date(); // Or Date.today()
var tomorrow = today.add(1).day();

Here is an answer that conserves GMT and time of the initial date

var date = new Date();_x000D_
_x000D_
var first_date = new Date(date); //Make a copy of the date we want the first and last days from_x000D_
first_date.setUTCDate(1); //Set the day as the first of the month_x000D_
_x000D_
var last_date = new Date(first_date); //Make a copy of the calculated first day_x000D_
last_date.setUTCMonth(last_date.getUTCMonth() + 1); //Add a month_x000D_
last_date.setUTCDate(0); //Set the date to 0, this goes to the last day of the previous month_x000D_
_x000D_
console.log(first_date.toJSON().substring(0, 10), last_date.toJSON().substring(0, 10)); //Log the dates with the format yyyy-mm-dd

Simple code that gives you the difference with multiple items if you want that:

a=[1,2,3,3,4]
b=[2,4]
tmp = copy.deepcopy(a)
for k in b:
    if k in tmp:
        tmp.remove(k)
print(tmp)

For PostgreSQL 9.3 or less...Or who likes all normalized to text

Three flavors of my old SwissKnife library: relname_exists(anyThing), relname_normalized(anyThing) and relnamechecked_to_array(anyThing). All checks from pg_catalog.pg_class table, and returns standard universal datatypes (boolean, text or text[]).

/**

 * Check and normalize to array the free-parameter relation-name.

     SELECT array[n.nspname::text, c.relname::text]

in order to get the ^M character to match I had to visually select it and then use the OS copy to clipboard command to retrieve it. You can test it by doing a search for the character before trying the replace command.

/^M

should select the first bad line

:%s/^M/\r/g

will replace all the errant ^M with carriage returns.

This is as functions in MacVim, which is based on gvim 7.

EDIT:

Having this problem again on my Windows 10 machine, which has Ubuntu for Windows, and I think this is causing fileformat issues for vim. In this case changing the ff to unix, mac, or dos did nothing other than to change the ^M to ^J and back again.

The solution in this case:

:%s/\r$/ /g
:%s/ $//g

The reason I went this route is because I wanted to ensure I was being non-destructive with my file. I could have :%s/\r$//g but that would have deleted the carriage returns right out, and could have had unexpected results. Instead we convert the singular CR character, here a ^M character, into a space, and then remove all spaces at the end of lines (which for me is a desirable result regardless)

Sorry for reviving an old question that has long since been answered, but there seemed to be some confusion afoot and I thought I'd help clear some of that up since this is coming up high in google searches.

Hm, looking at your first set of code, I think you have retrieved (maybe?) the hard drive model. The serial # comes from Win32_PhysicalMedia.

Get Hard Drive model

    ManagementObjectSearcher searcher = new
    ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");

   foreach(ManagementObject wmi_HD in searcher.Get())
   {
    HardDrive hd = new HardDrive();
    hd.Model = wmi_HD["Model"].ToString();
    hd.Type  = wmi_HD["InterfaceType"].ToString(); 
    hdCollection.Add(hd);
   }

Get the Serial Number

 searcher = new
    ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");

   int i = 0;
   foreach(ManagementObject wmi_HD in searcher.Get())
   {
    // get the hard drive from collection
    // using index
    HardDrive hd = (HardDrive)hdCollection[i];

    // get the hardware serial no.
    if (wmi_HD["SerialNumber"] == null)
     hd.SerialNo = "None";
    else
     hd.SerialNo = wmi_HD["SerialNumber"].ToString();

    ++i;
   }

Hope this helps :)

If you are reading from a file then you should hear the advice given and just put it into a double.

On the other hand, if you do have, say, a string you could use boost's lexical_cast.

Here is a (very simple) example:

int Foo(std::string anInt)
{
   return lexical_cast<int>(anInt);
}

You can proxyfy references to your object with, for example, dictionary singleton. You may store not object, but its ID or hash and access it trought the dictionary. Then when you need to remove the object you set value for its key to null.

For my project, I am set up to use https. I just got a new computer and cloned the project in git. The protocol and port number for the project are not saved in the solution file, so you have to make sure to set it again.

1. You can use the FindIndex() method to find the index of item.
2. Create a new list item.
3. Override indexed item with the new item.

List<Class1> list = new List<Class1>();

int index = list.FindIndex(item => item.Number == textBox6.Text);

Class1 newItem = new Class1();
newItem.Prob1 = "SomeValue";

list[index] = newItem;

$("a[href*='id=ABC']").addClass('active_jquery_menu');

the best way (for me) to make it it's the next infrastructure:

<form method="POST">
<input type="submit" formaction="default_url_when_press_enter" style="visibility: hidden; display: none;">
<!-- all your inputs -->
<input><input><input>
<!-- all your inputs -->
<button formaction="action1">Action1</button>
<button formaction="action2">Action2</button>
<input type="submit" value="Default Action">
</form>

with this structure you will send with enter a direction and the infinite possibilities for the rest of buttons.

You need to handle it via ajax submit.

Something like this:

$(function(){
    $('#subscribe-email-form').on('submit', function(e){
        e.preventDefault();
        $.ajax({
            url: url, //this is the submit URL
            type: 'GET', //or POST
            data: $('#subscribe-email-form').serialize(),
            success: function(data){
                 alert('successfully submitted')
            }
        });
    });
});

A better way would be to use a django form, and then render the following snippet:

<form>
    <div class="modal-body">
        <input type="email" placeholder="email"/>
        <p>This service will notify you by email should any issue arise that affects your plivo service.</p>
    </div>
    <div class="modal-footer">
        <input type="submit" value="SUBMIT" class="btn"/>
    </div>
</form>

via the context - example : {{form}}.

This should work:

#!/bin/bash

if [ "$#" -eq 0 ] || [ "$#" -gt 1 ] ; then
    echo "hello"
fi

I'm not sure if this is different in other shells but if you wish to use <, >, you need to put them inside double parenthesis like so:

if (("$#" > 1))
 ...

This helped me to call API that was using cookie authentication. I have passed authorization in header like this:

request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));

complete code:

// utility method to read the cookie value:
        public static string ReadCookie(string cookieName)
        {
            var cookies = HttpContext.Current.Request.Cookies;
            var cookie = cookies.Get(cookieName);
            if (cookie != null)
                return cookie.Value;
            return null;
        }

// using statements where you are creating your webclient
using System.Web.Script.Serialization;
using System.Net;
using System.IO;

// WebClient:

var requestUrl = "<API_url>";
var postRequest = new ClassRoom { name = "kushal seth" };

using (var webClient = new WebClient()) {
      JavaScriptSerializer serializer = new JavaScriptSerializer();
      byte[] requestData = Encoding.ASCII.GetBytes(serializer.Serialize(postRequest));
      HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;
      request.Method = "POST";
      request.ContentType = "application/json";                        
      request.ContentLength = requestData.Length;
      request.ContentType = "application/json";
      request.Expect = "application/json";
      request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));
      request.GetRequestStream().Write(requestData, 0, requestData.Length);

      using (var response = (HttpWebResponse)request.GetResponse()) {
         var reader = new StreamReader(response.GetResponseStream());
         var objText = reader.ReadToEnd(); // objText will have the value
      }
}

I like a @GLee approach and using it with fragment like below.

@Override
public void onBackPressed() {
    if(isTaskRoot()) {
        new ExitDialogFragment().show(getSupportFragmentManager(), null);
    } else {
        super.onBackPressed();
    }
}

Dialog using Fragment:

public class ExitDialogFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new AlertDialog.Builder(getActivity())
            .setTitle(R.string.exit_question)
            .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    getActivity().finish();
                }
            })
            .setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    getDialog().cancel();
                }
            })
            .create();
    }
}

Thread.sleep() is simple for the beginners and may be appropriate for unit tests and proofs of concept.

But please DO NOT use sleep() for production code. Eventually sleep() may bite you badly.

Best practice for multithreaded/multicore java applications to use the "thread wait" concept. Wait releases all the locks and monitors held by the thread, which allows other threads to acquire those monitors and proceed while your thread is sleeping peacefully.

Code below demonstrates that technique:

import java.util.concurrent.TimeUnit;
public class DelaySample {
    public static void main(String[] args) {
       DelayUtil d = new DelayUtil();
       System.out.println("started:"+ new Date());
       d.delay(500);
       System.out.println("half second after:"+ new Date());
       d.delay(1, TimeUnit.MINUTES); 
       System.out.println("1 minute after:"+ new Date());
    }
}

DelayUtil implementation:

import java.util.concurrent.TimeUnit;
import java.util.concurrent.locks.Condition;
import java.util.concurrent.locks.ReentrantLock;

public class DelayUtil {
    /** 
    *  Delays the current thread execution. 
    *  The thread loses ownership of any monitors. 
    *  Quits immediately if the thread is interrupted
    *  
    * @param durationInMillis the time duration in milliseconds
    */
   public void delay(final long durationInMillis) {
      delay(durationInMillis, TimeUnit.MILLISECONDS);
   }

   /** 
    * @param duration the time duration in the given {@code sourceUnit}
    * @param unit
    */
    public void delay(final long duration, final TimeUnit unit) {
        long currentTime = System.currentTimeMillis();
        long deadline = currentTime+unit.toMillis(duration);
        ReentrantLock lock = new ReentrantLock();
        Condition waitCondition = lock.newCondition();

        while ((deadline-currentTime)>0) {
            try {
                lock.lockInterruptibly();    
                waitCondition.await(deadline-currentTime, TimeUnit.MILLISECONDS);
            } catch (InterruptedException e) {
                Thread.currentThread().interrupt();
                return;
            } finally {
                lock.unlock();
            }
            currentTime = System.currentTimeMillis();
        }
    }
}

The Why

java.util.logging has a root logger that defaults to Level.INFO, and a ConsoleHandler attached to it that also defaults to Level.INFO. FINE is lower than INFO, so fine messages are not displayed by default.

Solution 1

Create a logger for your whole application, e.g. from your package name or use Logger.getGlobal(), and hook your own ConsoleLogger to it. Then either ask root logger to shut up (to avoid duplicate output of higher level messages), or ask your logger to not forward logs to root.

public static final Logger applog = Logger.getGlobal();
...

// Create and set handler
Handler systemOut = new ConsoleHandler();
systemOut.setLevel( Level.ALL );
applog.addHandler( systemOut );
applog.setLevel( Level.ALL );

// Prevent logs from processed by default Console handler.
applog.setUseParentHandlers( false ); // Solution 1
Logger.getLogger("").setLevel( Level.OFF ); // Solution 2

Solution 2

Alternatively, you may lower the root logger's bar.

You can set them by code:

Logger rootLog = Logger.getLogger("");
rootLog.setLevel( Level.FINE );
rootLog.getHandlers()[0].setLevel( Level.FINE ); // Default console handler

Or with logging configuration file, if you are using it:

.level = FINE
java.util.logging.ConsoleHandler.level = FINE

By lowering the global level, you may start seeing messages from core libraries, such as from some Swing or JavaFX components. In this case you may set a Filter on the root logger to filter out messages not from your program.

I am guessing that you are running the file using Run | Run File (or shift-F6) rather than Run | Run Main Project. The NetBeans 7.1 help file (F1 is your friend!) states for the Arguments parameter:

Add arguments to pass to the main class during application execution. Note that arguments cannot be passed to individual files.

I verified this with a little snippet of code:

public class Junk
{
    public static void main(String[] args)
    {
        for (String s : args)
            System.out.println("arg -> " + s);
    }
}

I set Run -> Arguments to x y z. When I ran the file by itself I got no output. When I ran the project the output was:

arg -> x
arg -> y
arg -> z

Following can be used as a common method to return different arguments on different method calls. Only thing we need to do is we need to pass an array with order in which objects should be retrieved in each call.

@SafeVarargs
public static <Mock> Answer<Mock> getAnswerForSubsequentCalls(final Mock... mockArr) {
    return new Answer<Mock>() {
       private int count=0, size=mockArr.length;
       public Mock answer(InvocationOnMock invocation) throws throwable {
           Mock mock = null;
           for(; count<size && mock==null; count++){
                mock = mockArr[count];
           }

           return mock;    
       } 
    }
}

Ex. getAnswerForSubsequentCalls(mock1, mock3, mock2); will return mock1 object on first call, mock3 object on second call and mock2 object on third call. Should be used like when(something()).doAnswer(getAnswerForSubsequentCalls(mock1, mock3, mock2)); This is almost similar to when(something()).thenReturn(mock1, mock3, mock2);

Guys found the perfect way to monitor ALL traffic that is flowing locally between requests from my machine to my machine:

1. Install Wireshark

2. When you need to capture traffic that is flowing from a localhost to a localhost then you will struggle to use wireshark as this only monitors incoming traffic on the network card. The way to do this is to add a route to windows that will force all traffic through a gateway and this be captured on the network interface.

   To do this, add a route with <ip address> <gateway>:

    cmd> route add 192.168.20.30 192.168.20.1
   

3. Then run a capture on wireshark (make sure you select the interface that has bytes flowing through it) Then filter.

The newly added routes will come up in black. (as they are local addresses)

Try this:

public interface MyService {
 //Code
}

@Component("One")
public class MyServiceOne implements MyService {
 //Code
}

@Component("Two")
public class MyServiceTwo implements MyService {
 //Code
}

I use Spring Boot, my solution to the problem was

Hope it helps someone.

This is answering a slightly different question, but since I got stuck on this myself, I hope it might be useful for someone else.

If you want to use allow_redirects=False and get directly to the first redirect object, rather than following a chain of them, and you just want to get the redirect location directly out of the 302 response object, then r.url won't work. Instead, it's the "Location" header:

r = requests.get('http://github.com/', allow_redirects=False)
r.status_code  # 302
r.url  # http://github.com, not https.
r.headers['Location']  # https://github.com/ -- the redirect destination

One thing I've learnt the hard way is being consistent

Watch out for mixing:

 import { BehaviorSubject } from "rxjs";

with

 import { BehaviorSubject } from "rxjs/BehaviorSubject";

This will probably work just fine UNTIL you try to pass the object to another class (where you did it the other way) and then this can fail

 (myBehaviorSubject instanceof Observable)

It fails because the prototype chain will be different and it will be false.

I can't pretend to understand exactly what is happening but sometimes I run into this and need to change to the longer format.

Same with something more complex...getting the ec2 instance region from within the instance.

INSTANCE_REGION=$(curl -s 'http://169.254.169.254/latest/dynamic/instance-identity/document' | python -c "import sys, json; print json.load(sys.stdin)['region']")

echo $INSTANCE_REGION

Sync didn't help me. Neither helped invalidating cache. I simply removed and cloned again the repository and it worked:

1. Make sure you have no uncommitted changes
2. Sync your local repository with remote github
3. Delete folder with the local repository
4. Clone the repository from github to local again
5. Open the cloned repository in the Android Studio
6. Build and run it again.

Funkodebat posted a great solution which I have referenced many times. Still, I find myself writing my own working model each time I need this. So, here is my working model... with some added clarity.

First of all, the height of the text is equal to the pixel font size. Now, this was something I read a while ago, and it has worked out in my calculations. I'm not sure if this works with all fonts, but it seems to work with Arial, sans-serif.

Also, to make sure that you fit all of the text in your canvas (and don't trim the tails off of your "p"'s) you need to set context.textBaseline*.

You will see in the code that we are rotating the text about its center. To do this, we need to set context.textAlign = "center" and the context.textBaseline to bottom, otherwise, we trim off parts of our text.

Why resize the canvas? I usually have a canvas that isn't appended to the page. I use it to draw all of my rotated text, then I draw it onto another canvas which I display. For example, you can use this canvas to draw all of the labels for a chart (one by one) and draw the hidden canvas onto the chart canvas where you need the label (context.drawImage(hiddenCanvas, 0, 0);).

IMPORTANT NOTE: Set your font before measuring your text, and re-apply all of your styling to the context after resizing your canvas. A canvas's context is completely reset when the canvas is resized.

Hope this helps!

From your example, it seems to me you want to use a static method.

class mystuff:
  @staticmethod
  def average(a,b,c): #get the average of three numbers
    result=a+b+c
    result=result/3
    return result

print mystuff.average(9,18,27)

Please note that an heavy usage of static methods in python is usually a symptom of some bad smell - if you really need functions, then declare them directly on module level.

About the INT, TINYINT... These are different data types, INT is 4-byte number, TINYINT is 1-byte number. More information here - INTEGER, INT, SMALLINT, TINYINT, MEDIUMINT, BIGINT.

The syntax of TINYINT data type is TINYINT(M), where M indicates the maximum display width (used only if your MySQL client supports it).

Numeric Type Attributes.

You don't escape quotes in regular expressions

this.Vals.replace(/["']/g, "")

UILabel *textLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 150, 30)];
[textLabel sizeToFit];
textLabel.numberOfLines = 0;
textLabel.text = @"Your String...";

I was getting this one on this case

...
.then((error: any, response: any) => {
  console.info('document error: ', error);
  console.info('documenr response: ', response);
  return new MyModel();

on this case making parameters optional would make ts stop complaining

.then((error?: any, response?: any) => {

I prefer an answer from Best way to print the result of a bool as 'false' or 'true' in c?, just like

printf("%s\n", "false\0true"+6*x);

• x == 0, "false\0true"+ 0" it means "false";
• x == 1, "false\0true"+ 6" it means "true";

This is just a concept, but don't implement this without security checks and filtering! Otherwise script could hack your site!

Answer: if you control target site, you can setup the receiver script like:

1) set the iframe link with style parameter, like:

http://your_site.com/target.php?color=red

(the last phrase is a{color:red} encoded by urlencode function.

2) set the receiver page target.php like this:

<head>
..........
$col = FILTER_VAR(SANITIZE_STRING, $_GET['color']);
<style>.xyz{color: <?php echo (in_array( $col, ['red','yellow','green'])?  $col : "black") ;?> } </style>
..........

execute below line:
  SET FOREIGN_KEY_CHECKS = 0;


FOREIGN_KEY_CHECKS option specifies whether or not to check foreign key constraints for InnoDB tables. 

-- Specify to check foreign key constraints (this is the default)

    SET FOREIGN_KEY_CHECKS = 1;
 

-- Do not check foreign key constraints

   SET FOREIGN_KEY_CHECKS = 0;


When to Use :
Temporarily disabling referential constraints (set FOREIGN_KEY_CHECKS to 0) is useful when you need to re-create the tables and load data in any parent-child order.

The problem is, I think, that JPA was never incepted with the idea in mind that we could have a complex preexisting Schema already in place.

I think there are two main shortcomings resulting from this, specific to Enum:

1. The limitation of using name() and ordinal(). Why not just mark a getter with @Id, the way we do with @Entity?
2. Enum's have usually representation in the database to allow association with all sorts of metadata, including a proper name, a descriptive name, maybe something with localization etc. We need the easy of use of an Enum combined with the flexibility of an Entity.

Help my cause and vote on JPA_SPEC-47

Would this not be more elegant than using a @Converter to solve the problem?

// Note: this code won't work!!
// it is just a sample of how I *would* want it to work!
@Enumerated
public enum Language {
  ENGLISH_US("en-US"),
  ENGLISH_BRITISH("en-BR"),
  FRENCH("fr"),
  FRENCH_CANADIAN("fr-CA");
  @ID
  private String code;
  @Column(name="DESCRIPTION")
  private String description;

  Language(String code) {
    this.code = code;
  }

  public String getCode() {
    return code;
  }

  public String getDescription() {
    return description;
  }
}

Try to use the <font> tag

?<table> 
    <thead> 
        <tr> 
            <th><font color="#FFF">Header 1</font></th> 
            <th><font color="#FFF">Header 1</font></th> 
            <th><font color="#FFF">Header 1</font></th> 
        </tr> 
    </thead> 
    <tbody> 
        <tr> 
            <td>blah blah</td> 
            <td>blah blah</td> 
            <td>blah blah</td> 
        </tr> 
    </tbody> 
</table>

But I think this should work, too:

?<table> 
    <thead> 
        <tr> 
            <th color="#FFF">Header 1</th> 
            <th color="#FFF">Header 1</th> 
            <th color="#FFF">Header 1</th> 
        </tr> 
    </thead> 
    <tbody> 
        <tr> 
            <td>blah blah</td> 
            <td>blah blah</td> 
            <td>blah blah</td> 
        </tr> 
    </tbody> 
</table>

EDIT:

Crossbrowser solution:

use capitals in HEX-color.

You can easily convert object into urlencoded string:

function objToUrlEncode(obj, keys) {
    let str = "";
    keys = keys || [];
    for (let key in obj) {
        keys.push(key);
        if (typeof (obj[key]) === 'object') {
            str += objToUrlEncode(obj[key], keys);
        } else {
            for (let i in keys) {
                if (i == 0) str += keys[0];
                else str += `[${keys[i]}]`
            }
            str += `=${obj[key]}&`;
            keys.pop();
        }
    }
    return str;
}

console.log(objToUrlEncode({ key: 'value', obj: { obj_key: 'obj_value' } }));

// key=value&obj[obj_key]=obj_value&

NSDictionary *navbarTitleTextAttributes = @{NSForegroundColorAttributeName:[UIColor whiteColor],
                                            NSShadowAttributeName:titleShadow};

Just as Commonsware mentioned, you shouldn't assume, that the stream you get via ContentResolver is convertable into file.

What you really should do is to open the InputStream from the ContentProvider, then create a Bitmap out of it. And it works on 4.4 and earlier versions as well, no need for reflection.

    //cxt -> current context

    InputStream input;
    Bitmap bmp;
    try {
        input = cxt.getContentResolver().openInputStream(fileUri);
        bmp = BitmapFactory.decodeStream(input);
    } catch (FileNotFoundException e1) {

    }

Of course if you handle big images, you should load them with appropriate inSampleSize: http://developer.android.com/training/displaying-bitmaps/load-bitmap.html. But that's another topic.

format = '%Y-%m-%d %H:%M %p'

The format is using %H instead of %I. Since %H is the "24-hour" format, it's likely just discarding the %p information. It works just fine if you change the %H to %I.

FAT32 along with FAT16 and FAT12 are File System Types, but vfat along with umsdos and msdos are drivers, used to mount the FAT file systems in Linux. The choosing of the driver determines how some of the features are applied to the file system, for example, systems mounted with msdos driver don't have long filenames (they are 8.3 format). vfat is the most common driver for mounting FAT32 file systems nowadays.

Source: this wikipedia article

Output of commands like df and lsblk indeed show vfat as the File System Type. But sudo file -sL /dev/<partition> shows FAT (32 bit) if a File System is FAT32.

You can confirm vfat is a module and not a File System Type by running modinfo vfat.

I would go with Swing. For layout I would use JGoodies form layout. Its worth studying the white paper on the Form Layout here - http://www.jgoodies.com/freeware/forms/

Also if you are going to start developing a huge desktop application, you will definitely need a framework. Others have pointed out the netbeans framework. I didnt like it much so wrote a new one that we now use in my company. I have put it onto sourceforge, but didnt find the time to document it much. Here's the link to browse the code:

There are two ways to delete a stash:

1. If you no longer need a particular stash, you can delete it with: $ git stash drop <stash_id>.
2. You can delete all of your stashes from the repo with: $ git stash clear.

Use both of them with caution, it maybe is difficult to revert the once deleted stashes.

Sleep is used in cases where independent program(s) that you have no control over may sometimes use a commonly used resource (say, a file), that your program needs to access when it runs, and when the resource is in use by these other programs your program is blocked from using it. In this case, where you access the resource in your code, you put your access of the resource in a try-catch (to catch the exception when you can't access the resource), and you put this in a while loop. If the resource is free, the sleep never gets called. But if the resource is blocked, then you sleep for an appropriate amount of time, and attempt to access the resource again (this why you're looping). However, bear in mind that you must put some kind of limiter on the loop, so it's not a potentially infinite loop. You can set your limiting condition to be N number of attempts (this is what I usually use), or check the system clock, add a fixed amount of time to get a time limit, and quit attempting access if you hit the time limit.

FORCE_INDEX is going to be deprecated after MySQL 8:

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

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

The thing about collations is that although the database has its own collation, every table, and every column can have its own collation. If not specified it takes the default of its parent object, but can be different.

When you change collation of the database, it will be the new default for all new tables and columns, but it doesn't change the collation of existing objects inside the database. You have to go and change manually the collation of every table and column.

Luckily there are scripts available on the internet that can do the job. I am not going to recommend any as I haven't tried them but here are few links:

http://www.codeproject.com/Articles/302405/The-Easy-way-of-changing-Collation-of-all-Database

Update Collation of all fields in database on the fly

http://www.sqlservercentral.com/Forums/Topic820675-146-1.aspx

If you need to have different collation on two objects or can't change collations - you can still JOIN between them using COLLATE command, and choosing the collation you want for join.

SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE Latin1_General_CI_AS 

or using default database collation:

SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE DATABASE_DEFAULT

WHERE ID not in (SELECT TOP(5) ID From My_TABLE);

This approach will work in any SQL version.

Answer given by @mpm is not working it gives the error

Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys. Repeater: {0}, Duplicate key: {1}

To avoid this along with

ng-repeat="t in getTimes(4)"

use

track by $index

like this

<div ng-repeat="t in getTimes(4) track by $index">TEXT</div>

Click -> Edit Source Lookup Path

after then

Click -> Add finally select Java project and select project path.

This just mean you forgot to do the initial commit, try

git add .
git commit -m 'initial commit'
git push origin master

I tried with:

<ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:contentDescription="@string/get_started"
        android:src="@drawable/home_started"
        style="?android:borderlessButtonStyle"
        android:adjustViewBounds="true"
        android:clickable="true"
        android:elevation="5dp"
        android:longClickable="true" />

and this worked. Please note on the line: style="?android:borderlessButtonStyle"

The Array.prototype property represents the prototype for the Array constructor and allows you to add new properties and methods to all Array objects. we can create a prototype for this purpose

Array.prototype.has_element = function(element) {
    return $.inArray( element, this) !== -1;
};

And then use it like this

var numbers= [1, 2, 3, 4];
numbers.has_element(3) => true
numbers.has_element(10) => false

See the Demo below

Array.prototype.has_element = function(element) {_x000D_
  return $.inArray(element, this) !== -1;_x000D_
};_x000D_
_x000D_
_x000D_
_x000D_
var numbers = [1, 2, 3, 4];_x000D_
console.log(numbers.has_element(3));_x000D_
console.log(numbers.has_element(10));

In my case, along with Mekanik's suggestions, I was receiving this error in Windows Server 2012 and I had to tick "HTTP Activation" in "Add Role Services".

You would have to first create your migration for the model basics then you create another migration to modify your previous using the change_column ...

def change
    change_column :widgets, :colour, :string, default: 'red'
end

For those looking for an entirely programmatic (or at least server-side) solution, I've had great success using catdoc's xls2csv tool.

Install catdoc:

apt-get install catdoc

Do the conversion:

xls2csv -d utf-8 file.xls > file-utf-8.csv 

This is blazing fast.

Note that it's important that you include the -d utf-8 flag, otherwise it will encode the output in the default cp1252 encoding, and you run the risk of losing information.

Note that xls2csv also only works with .xls files, it does not work with .xlsx files.

With your private key and public certificate, you need to create a PKCS12 keystore first, then convert it into a JKS.

# Create PKCS12 keystore from private key and public certificate.
openssl pkcs12 -export -name myservercert -in selfsigned.crt -inkey server.key -out keystore.p12

# Convert PKCS12 keystore into a JKS keystore
keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert

To verify the contents of the JKS, you can use this command:

keytool -list -v -keystore mykeystore.jks

If this was not a self-signed certificate, you would probably want to follow this step with importing the certificate chain leading up to the trusted CA cert.

If you mean a minimal form, go with this:

if (not a or not b or not c) and (a or b or c):

Which translates the title of your question.

UPDATE: as correctly said by Volatility and Supr, you can apply De Morgan's law and obtain equivalent:

if (a or b or c) and not (a and b and c):

My advice is to use whichever form is more significant to you and to other programmers. The first means "there is something false, but also something true", the second "There is something true, but not everything". If I were to optimize or do this in hardware, I would choose the second, here just choose the most readable (also taking in consideration the conditions you will be testing and their names). I picked the first.

For some reason no one has mentioned the fact that the bashrc needs to be re-sourced after editing. You can either log out and log back in (like mentioned above) but you can also use the commands: source ~/.bashrc or . ~/.bashrc.

Following the answer by @seangwright, I've written an abstract class that handles "infinite" observables' subscriptions in components:

import { OnDestroy } from '@angular/core';
import { Subscription } from 'rxjs/Subscription';
import { Subject } from 'rxjs/Subject';
import { Observable } from 'rxjs/Observable';
import { PartialObserver } from 'rxjs/Observer';

export abstract class InfiniteSubscriberComponent implements OnDestroy {
  private onDestroySource: Subject<any> = new Subject();

  constructor() {}

  subscribe(observable: Observable<any>): Subscription;

  subscribe(
    observable: Observable<any>,
    observer: PartialObserver<any>
  ): Subscription;

  subscribe(
    observable: Observable<any>,
    next?: (value: any) => void,
    error?: (error: any) => void,
    complete?: () => void
  ): Subscription;

  subscribe(observable: Observable<any>, ...subscribeArgs): Subscription {
    return observable
      .takeUntil(this.onDestroySource)
      .subscribe(...subscribeArgs);
  }

  ngOnDestroy() {
    this.onDestroySource.next();
    this.onDestroySource.complete();
  }
}

To use it, just extend it in your angular component and call the subscribe() method as follows:

this.subscribe(someObservable, data => doSomething());

It also accepts the error and complete callbacks as usual, an observer object, or not callbacks at all. Remember to call super.ngOnDestroy() if you are also implementing that method in the child component.

Find here an additional reference by Ben Lesh: RxJS: Don’t Unsubscribe.

In the below mentioned link, ChromeDriver.exe for Windows 32 bit exist.

http://chromedriver.storage.googleapis.com/index.html?path=2.24/

It is working for me in Win7 64 bit.

Yes, this is achievable:

String s1 = "abBaCca";
String s2 = "bac";

String s1Lower = s1;

//s1Lower is exact same string, now convert it to lowercase, I left the s1 intact for print purposes if needed

s1Lower = s1Lower.toLowerCase();

String trueStatement = "FALSE!";
if (s1Lower.contains(s2)) {

    //THIS statement will be TRUE
    trueStatement = "TRUE!"
}

return trueStatement;

This code will return the String "TRUE!" as it found that your characters were contained.

You can use this example and change it's implementation like this:

[self enumerateAttribute:NSParagraphStyleAttributeName
                 inRange:NSMakeRange(0, self.length)
                 options:0
              usingBlock:^(id  _Nullable value, NSRange range, BOOL * _Nonnull stop) {
                  NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];

                  //add your specific settings for paragraph
                  //...
                  //...

                  [self removeAttribute:NSParagraphStyleAttributeName range:range];
                  [self addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:range];
              }];

Regularization can help. For a classifier, there is a good case for activity regularization, whether it is binary or a multi-class classifier. For a regressor, kernel regularization might be more appropriate.

Try this:

location / {
    root /path/to/root;
    expires 30d;
    access_log off;
}

location ~* ^.*\.php$ {
    if (!-f $request_filename) {
        return 404;
    }
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

Hopefully it works. Regular expressions have higher priority than plain strings, so all requests ending in .php should be forwared to Apache if only a corresponding .php file exists. Rest will be handled as static files. The actual algorithm of evaluating location is here.

No, since the other option is modifying the Zend engine, and one would be hard-pressed to call that a "better way".

Edit:

If you really wanted to, you could use an array:

$boolarray = Array(false => 'false', true => 'true');
echo $boolarray[false];

foreach only works with a single array. To step through multiple arrays, it's better to use the each() function in a while loop:

while(($code = each($codes)) && ($name = each($names))) {
    echo '<option value="' . $code['value'] . '">' . $name['value'] . '</option>';
}

each() returns information about the current key and value of the array and increments the internal pointer by one, or returns false if it has reached the end of the array. This code would not be dependent upon the two arrays having identical keys or having the same sort of elements. The loop terminates when one of the two arrays is finished.

Based on your screenshot i found two working solutions:

First solution: add to dependencies of your gradle module this line

compile 'com.android.support:support-annotations:27.1.1'

and sync your project

Note: if you are using Android studio 3+ change compile to implementation

Second solution: Configure project-wide properties found in the documentation https://developer.android.com/studio/build/gradle-tips.html#configure-project-wide-properties

in project gradle add this line:

// This block encapsulates custom properties and makes them available to all
// modules in the project.
ext {
    // The following are only a few examples of the types of properties you can define.
    compileSdkVersion = 26
    // You can also use this to specify versions for dependencies. Having consistent
    // versions between modules can avoid behavior conflicts.
    supportLibVersion = "27.1.1"
}

Then to access this section change compileSdkVersionline to be

compileSdkVersion rootProject.ext.compileSdkVersion

and at dependencies section change the imported library to be like this:

compile "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"

and sync your project

Note: if you are using Android studio 3+ change compile to implementation

For the difference between compile and implementation look at this What's the difference between implementation and compile in gradle

If you want to check the python version in a particular cond environment you can also use conda list python

if you try with lubridate:

library(lubridate)
lubridate::week(ymd("2014-03-16", "2014-03-17","2014-03-18", '2014-01-01'))

[1] 11 11 12  1

The pattern is the same. Try isoweek

lubridate::isoweek(ymd("2014-03-16", "2014-03-17","2014-03-18", '2014-01-01'))
[1] 11 12 12  1

To auto-select the value of in select.

<div className="form-group">
    <label htmlFor="contactmethod">Contact Method</label>
    <select id="contactmethod" className="form-control"  value={this.state.contactmethod || ''} onChange={this.handleChange} name="contactmethod">
    <option value='Email'>URL</option>
    <option value='Phone'>Phone</option>
    <option value="SMS">SMS</option>
    </select>
</div>

Use the value attribute in the select tag

value={this.state.contactmethod || ''}

the solution is working for me.

CSS can not be used to animation, or any style modification on events.

The only way is to use a javascript function, which will return the width of a given element, then, subtract 100px to it, and set the new width size.

Assuming you are using jQuery, you could do something like that:

oldWidth = $('#yourElem').width();
$('#yourElem').width(oldWidth-100);

And with native javascript:

oldWidth = document.getElementById('yourElem').clientWidth;
document.getElementById('yourElem').style.width = oldWidth-100+'px';

We assume that you have a css style set with 100%;

Try this, it will work:

CONVERT(VARCHAR(8),DATETIME,114)

For your reference.

select *
into #TempTable
from SomeTale

select *
from #TempTable

How about this?

class name(str):
    def __init__(self, name):
        print (name)
# ------
person1 = name("jean")
person2 = name("dean")
print('===')
print(person1)
print(person2)

Output:

jean
dean
===
jean
dean

Use %03d in the format specifier for the integer. The 0 means that the number will be zero-filled if it is less than three (in this case) digits.

See the Formatter docs for other modifiers.

Better use a library like Guava:

import com.google.common.collect.Lists;

Iterator<Element> myIterator = ... //some iterator
List<Element> myList = Lists.newArrayList(myIterator);

Another Guava example:

ImmutableList.copyOf(myIterator);

or Apache Commons Collections:

import org.apache.commons.collections.IteratorUtils;

Iterator<Element> myIterator = ...//some iterator

List<Element> myList = IteratorUtils.toList(myIterator);       

-Confirm is a switch in most PowerShell cmdlets that forces the cmdlet to ask for user confirmation. What you're actually looking for is the Read-Host cmdlet:

$confirmation = Read-Host "Are you Sure You Want To Proceed:"
if ($confirmation -eq 'y') {
    # proceed
}

or the PromptForChoice() method of the host user interface:

$title    = 'something'
$question = 'Are you sure you want to proceed?'

$choices = New-Object Collections.ObjectModel.Collection[Management.Automation.Host.ChoiceDescription]
$choices.Add((New-Object Management.Automation.Host.ChoiceDescription -ArgumentList '&Yes'))
$choices.Add((New-Object Management.Automation.Host.ChoiceDescription -ArgumentList '&No'))

$decision = $Host.UI.PromptForChoice($title, $question, $choices, 1)
if ($decision -eq 0) {
    Write-Host 'confirmed'
} else {
    Write-Host 'cancelled'
}

Edit:

As M-pixel pointed out in the comments the code could be simplified further, because the choices can be passed as a simple string array.

$title    = 'something'
$question = 'Are you sure you want to proceed?'
$choices  = '&Yes', '&No'

$decision = $Host.UI.PromptForChoice($title, $question, $choices, 1)
if ($decision -eq 0) {
    Write-Host 'confirmed'
} else {
    Write-Host 'cancelled'
}

I'm no expert with DOM or Javascript/Typescript but I think that the DOM-Tags can't handle real javascript object somehow. But putting the whole object in as a string and parsing it back to an Object/JSON worked for me:

interface TestObject {
  name:string;
  value:number;
}

@Component({
  selector: 'app',
  template: `
      <h4>Select Object via 2-way binding</h4>

      <select [ngModel]="selectedObject | json" (ngModelChange)="updateSelectedValue($event)">
        <option *ngFor="#o of objArray" [value]="o | json" >{{o.name}}</option>
      </select>

      <h4>You selected:</h4> {{selectedObject }}
  `,
  directives: [FORM_DIRECTIVES]
})
export class App {
  objArray:TestObject[];
  selectedObject:TestObject;
  constructor(){
    this.objArray = [{name: 'foo', value: 1}, {name: 'bar', value: 1}];
    this.selectedObject = this.objArray[1];
  }
  updateSelectedValue(event:string): void{
    this.selectedObject = JSON.parse(event);
  }
}

You can use https://github.com/douzi8/ajax-request#download

request.download('http://res.m.ctrip.com/html5/Content/images/57.png', 
  function(err, res, body) {}
);

Try this for the file format:

[default]
aws_access_key_id=<your access key>
aws_secret_access_key=<your secret access key>

I saved this file as ~/.aws/credentials with ProfileCredentialsProvider().

Typically one would use an auxiliary numbers table you usually keep around for just this purpose with some variation on this:

SELECT *
FROM (
    SELECT DATEADD(d, number - 1, '2009-01-01') AS dt
    FROM Numbers
    WHERE number BETWEEN 1 AND DATEDIFF(d, '2009-01-01', '2009-01-13') + 1
) AS DateRange
LEFT JOIN YourStuff
    ON DateRange.dt = YourStuff.DateColumn

I've seen variations with table-valued functions, etc.

You can also keep a permanent list of dates. We have that in our data warehouse as well as a list of times of day.
