The simplest approach is probably to define one custom enum with just one case that has a String attached to it:

enum MyError: ErrorType {
    case runtimeError(String)
}

Or, as of Swift 4:

enum MyError: Error {
    case runtimeError(String)
}

Example usage would be something like:

func someFunction() throws {
    throw MyError.runtimeError("some message")
}
do {
    try someFunction()
} catch MyError.runtimeError(let errorMessage) {
    print(errorMessage)
}

If you wish to use existing Error types, the most general one would be an NSError, and you could make a factory method to create and throw one with a custom message.

Swift 3

you can use index(where:) in Swift 3

func index(where predicate: @noescape Element throws -> Bool) rethrows -> Int?

example

if let i = theArray.index(where: {$0.name == "Foo"}) {
    return theArray[i]
}

If you want to assert that the two lists are identical, don't complicate things with Hamcrest:

assertEquals(expectedList, actual.getList());

If you really intend to perform an order-insensitive comparison, you can call the containsInAnyOrder varargs method and provide values directly:

assertThat(actual.getList(), containsInAnyOrder("item1", "item2"));

(Assuming that your list is of String, rather than Agent, for this example.)

If you really want to call that same method with the contents of a List:

assertThat(actual.getList(), containsInAnyOrder(expectedList.toArray(new String[expectedList.size()]));

Without this, you're calling the method with a single argument and creating a Matcher that expects to match an Iterable where each element is a List. This can't be used to match a List.

That is, you can't match a List<Agent> with a Matcher<Iterable<List<Agent>>, which is what your code is attempting.

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

As you can see in the below source code, BeanUtils.copyProperties internally uses reflection and there's additional internal cache lookup steps as well which is going to add cost wrt performance

 private static void copyProperties(Object source, Object target, @Nullable Class<?> editable,
                @Nullable String... ignoreProperties) throws BeansException {

            Assert.notNull(source, "Source must not be null");
            Assert.notNull(target, "Target must not be null");

            Class<?> actualEditable = target.getClass();
            if (editable != null) {
                if (!editable.isInstance(target)) {
                    throw new IllegalArgumentException("Target class [" + target.getClass().getName() +
                            "] not assignable to Editable class [" + editable.getName() + "]");
                }
                actualEditable = editable;
            }
            **PropertyDescriptor[] targetPds = getPropertyDescriptors(actualEditable);**
            List<String> ignoreList = (ignoreProperties != null ? Arrays.asList(ignoreProperties) : null);

            for (PropertyDescriptor targetPd : targetPds) {
                Method writeMethod = targetPd.getWriteMethod();
                if (writeMethod != null && (ignoreList == null || !ignoreList.contains(targetPd.getName()))) {
                    PropertyDescriptor sourcePd = getPropertyDescriptor(source.getClass(), targetPd.getName());
                    if (sourcePd != null) {
                        Method readMethod = sourcePd.getReadMethod();
                        if (readMethod != null &&
                                ClassUtils.isAssignable(writeMethod.getParameterTypes()[0], readMethod.getReturnType())) {
                            try {
                                if (!Modifier.isPublic(readMethod.getDeclaringClass().getModifiers())) {
                                    readMethod.setAccessible(true);
                                }
                                Object value = readMethod.invoke(source);
                                if (!Modifier.isPublic(writeMethod.getDeclaringClass().getModifiers())) {
                                    writeMethod.setAccessible(true);
                                }
                                writeMethod.invoke(target, value);
                            }
                            catch (Throwable ex) {
                                throw new FatalBeanException(
                                        "Could not copy property '" + targetPd.getName() + "' from source to target", ex);
                            }
                        }
                    }
                }
            }
        }

So it's better to use plain setters given the cost reflection

Swift 5: The Codable protocol can be used instead of NSKeyedArchiever.

struct User: Codable {
    let id: String
    let mail: String
    let fullName: String
}

The Pref struct is custom wrapper around the UserDefaults standard object.

struct Pref {
    static let keyUser = "Pref.User"
    static var user: User? {
        get {
            if let data = UserDefaults.standard.object(forKey: keyUser) as? Data {
                do {
                    return try JSONDecoder().decode(User.self, from: data)
                } catch {
                    print("Error while decoding user data")
                }
            }
            return nil
        }
        set {
            if let newValue = newValue {
                do {
                    let data = try JSONEncoder().encode(newValue)
                    UserDefaults.standard.set(data, forKey: keyUser)
                } catch {
                    print("Error while encoding user data")
                }
            } else {
                UserDefaults.standard.removeObject(forKey: keyUser)
            }
        }
    }
}

So you can use it this way:

Pref.user?.name = "John"

if let user = Pref.user {...

indexPathsForVisibleItems might work for most situations, but sometimes it returns an array with more than one index path and it can be tricky figuring out the one you want. In those situations, you can do something like this:

CGRect visibleRect = (CGRect){.origin = self.collectionView.contentOffset, .size = self.collectionView.bounds.size};
CGPoint visiblePoint = CGPointMake(CGRectGetMidX(visibleRect), CGRectGetMidY(visibleRect));
NSIndexPath *visibleIndexPath = [self.collectionView indexPathForItemAtPoint:visiblePoint];

This works especially well when each item in your collection view takes up the whole screen.

Swift version

let visibleRect = CGRect(origin: collectionView.contentOffset, size: collectionView.bounds.size)
let visiblePoint = CGPoint(x: visibleRect.midX, y: visibleRect.midY)
let visibleIndexPath = collectionView.indexPathForItem(at: visiblePoint)

Most of the time,bootstrap project uses jQuery, so you can use jQuery.

Just get the width and height of parent with JQuery.offsetHeight() and JQuery.offsetWidth(), and set them to the child element with JQuery.width() and JQuery.height().

If you want to make it responsive, repeat the above steps in the $(window).resize(func), as well.

I found the best solution here, the key of this issue is the addEntity method

public static void testSimpleSQL() {
    final Session session = sessionFactory.openSession();
    SQLQuery q = session.createSQLQuery("select * from ENTITY");
    q.addEntity(Entity.class);
    List<Entity> entities = q.list();
    for (Entity entity : entities) {
        System.out.println(entity);
    }
}

The problem is that omega in your case is matrix of dimensions 1 * 1. You should convert it to a vector if you wish to multiply t(X) %*% X by a scalar (that is omega)

In particular, you'll have to replace this line:

omega   = rgamma(1,a0,1) / L0

with:

omega   = as.vector(rgamma(1,a0,1) / L0)

everywhere in your code. It happens in two places (once inside the loop and once outside). You can substitute as.vector(.) or c(t(.)). Both are equivalent.

Here's the modified code that should work:

gibbs = function(data, m01 = 0, m02 = 0, k01 = 0.1, k02 = 0.1, 
                     a0 = 0.1, L0 = 0.1, nburn = 0, ndraw = 5000) {
    m0      = c(m01, m02) 
    C0      = matrix(nrow = 2, ncol = 2) 
    C0[1,1] = 1 / k01 
    C0[1,2] = 0 
    C0[2,1] = 0 
    C0[2,2] = 1 / k02 
    beta    = mvrnorm(1,m0,C0) 
    omega   = as.vector(rgamma(1,a0,1) / L0)
    draws   = matrix(ncol = 3,nrow = ndraw) 
    it      = -nburn 

    while (it < ndraw) {
        it    = it + 1 
        C1    = solve(solve(C0) + omega * t(X) %*% X) 
        m1    = C1 %*% (solve(C0) %*% m0 + omega * t(X) %*% y)
        beta  = mvrnorm(1, m1, C1) 
        a1    = a0 + n / 2 
        L1    = L0 + t(y - X %*% beta) %*% (y - X %*% beta) / 2 
        omega = as.vector(rgamma(1, a1, 1) / L1)
        if (it > 0) { 
            draws[it,1] = beta[1]
            draws[it,2] = beta[2]
            draws[it,3] = omega
        }
    }
    return(draws)
}

There are two possible result rearrangements (following example by @eumiro). Einops package provides a powerful notation to describe such operations non-ambigously

>> a = np.arange(18).reshape(9,2)

# this version corresponds to eumiro's answer
>> einops.rearrange(a, '(x y) z -> z y x', x=3)

array([[[ 0,  6, 12],
        [ 2,  8, 14],
        [ 4, 10, 16]],

       [[ 1,  7, 13],
        [ 3,  9, 15],
        [ 5, 11, 17]]])

# this has the same shape, but order of elements is different (note that each paer was trasnposed)
>> einops.rearrange(a, '(x y) z -> z x y', x=3)

array([[[ 0,  2,  4],
        [ 6,  8, 10],
        [12, 14, 16]],

       [[ 1,  3,  5],
        [ 7,  9, 11],
        [13, 15, 17]]])

Background

MD2 was widely recognized as insecure and thus disabled in Java in version JDK 6u17 (see release notes http://www.oracle.com/technetwork/java/javase/6u17-141447.html, "Disable MD2 in certificate chain validation"), as well as JDK 7, as per the configuration you pointed out in java.security.

Verisign was using a Class 3 root certificate with the md2WithRSAEncryption signature algorithm (serial 70:ba:e4:1d:10:d9:29:34:b6:38:ca:7b:03:cc:ba:bf), but deprecated it and replaced it with another certificate with the same key and name, but signed with algorithm sha1WithRSAEncryption. However, some servers are still sending the old MD2 signed certificate during the SSL handshake (ironically, I ran into this problem with a server run by Verisign!).

You can verify that this is the case by getting the certificate chain from the server and examining it:

openssl s_client -showcerts -connect <server>:<port>

Recent versions of the JDK (e.g. 6u21 and all released versions of 7) should resolve this issue by automatically removing certs with the same issuer and public key as a trusted anchor (in cacerts by default).

If you still have this issue with newer JDKs

Check if you have a custom trust manager implementing the older X509TrustManager interface. JDK 7+ is supposed to be compatible with this interface, however based on my investigation when the trust manager implements X509TrustManager rather than the newer X509ExtendedTrustManager (docs), the JDK uses its own wrapper (AbstractTrustManagerWrapper) and somehow bypasses the internal fix for this issue.

The solution is to:

1. use the default trust manager, or

2. modify your custom trust manager to extend X509ExtendedTrustManager directly (a simple change).

The width attribute of <td> is deprecated in HTML 5.

Use CSS. e.g.

 <td style="width:100px">

in detail, like this:

<table >
  <tr>
    <th>Month</th>
    <th>Savings</th>
  </tr>
  <tr>
    <td style="width:70%">January</td>
    <td style="width:30%">$100</td>
  </tr>
  <tr>
    <td>February</td>
    <td>$80</td>
  </tr>
</table>

I was having the same issue when accessing a published ASP.NET Web Api. In my case, I realized that when I was about to publish the Web Api, I had not indicated a connection string inside the Databases section:

So I generated it using the three dot button, and after publishing, it worked.

What is weird, is that for a long time I am pretty sure that there was no connection string in that configuration but it still worked.

I had the same problem and finally I managed to resolve it in the following way:

The problem was in the connection string definition in my web.config.

<add name="DefaultConnection" connectionString="DefaultConnection_ConnectionString" providerName="System.Data.SqlClient"/>

The above worked perfect locally because I used a local Database when I managed users and roles. When I transfered my application to IIS the local DB was not longer accessible, in addition I would like to use my DB in SQL Server. So I change the above connection string the following SQL Server DB equivalent:

<add name="DefaultConnection" connectionString="data source=MY_SQL_SERVER; Initial Catalog=MY_DATABASE_NAME; Persist Security Info=true; User Id=sa;Password=Mybl00dyPa$$" providerName="System.Data.SqlClient"/>

NOTE: The above, also, suppose that you are going to use the same SQL Server from your local box (in case that you incorporate it into your local web.config - that is what exactly I did in my case).

You may use CString, CStringA, CStringW to do automatic conversions and convert between these types. Further, you may also use CStrBuf, CStrBufA, CStrBufW to get RAII pattern modifiable strings

You can increase the List View Threshold beyond the 5,000 default, but it is highly recommended that you don't, as it has performance implications. The recommended fix is to add an index to the field or fields used in the query (usually the ID field for a list or the Title field for a library).

When there is an index, that is used to retrieve the item(s); when there is no index the whole list is opened for a scan (and therefore hits the threshold). You create the index on the List (or Library) settings page.

This article is a good overview: http://office.microsoft.com/en-us/sharepoint-foundation-help/manage-lists-and-libraries-with-many-items-HA010377496.aspx

I would check them one-by-one; i.e. look for a number \d+, then if that fails you can tell the user they need to add a digit. This avoids returning an "Invalid" error without hinting to the user whats wrong with it.

I've found it helps to not write my code on my monitor's glass with a magic marker, even though it looks nice when its really black. The screen fills up too fast and then the people who give me a clean monitor call me names each week.

A couple of my employees (I'm a manager) are chipping in to buy me one of those red pad computers with the knobs. They said that I won't need markers and I can clean the screen myself when it's full but I have to be careful shaking it. I supposed it's delicate that way.

That's why I hire the smart people.

I haven't ever seen such a thing, but there is this dev tool that includes a syntax checker for oracle, mysql, db2, and sql server... http://www.sqlparser.com/index.php

However this seems to be just the library. You'd need to build an app to leverage the parser to do what you want. And the Enterprise edition that includes all of the databases would cost you $450... ouch!

EDIT: And, after saying that - it looks like someone might already have done what you want using that library: http://www.wangz.net/cgi-bin/pp/gsqlparser/sqlpp/sqlformat.tpl

The online tool doesn't automatically check against each DB though, you need to run each manually. Nor can I say how good it is at checking the syntax. That you'd need to investigate yourself.

I have converted the answer by Rafael Moreira. The credit goes to him. For those of you looking for the Swift version, here is the code:

 func zoomToFitMapAnnotations(aMapView: MKMapView) {
    guard aMapView.annotations.count > 0 else {
        return
    }
    var topLeftCoord: CLLocationCoordinate2D = CLLocationCoordinate2D()
    topLeftCoord.latitude = -90
    topLeftCoord.longitude = 180
    var bottomRightCoord: CLLocationCoordinate2D = CLLocationCoordinate2D()
    bottomRightCoord.latitude = 90
    bottomRightCoord.longitude = -180
    for annotation: MKAnnotation in myMap.annotations as! [MKAnnotation]{
        topLeftCoord.longitude = fmin(topLeftCoord.longitude, annotation.coordinate.longitude)
        topLeftCoord.latitude = fmax(topLeftCoord.latitude, annotation.coordinate.latitude)
        bottomRightCoord.longitude = fmax(bottomRightCoord.longitude, annotation.coordinate.longitude)
        bottomRightCoord.latitude = fmin(bottomRightCoord.latitude, annotation.coordinate.latitude)
    }

    var region: MKCoordinateRegion = MKCoordinateRegion()
    region.center.latitude = topLeftCoord.latitude - (topLeftCoord.latitude - bottomRightCoord.latitude) * 0.5
    region.center.longitude = topLeftCoord.longitude + (bottomRightCoord.longitude - topLeftCoord.longitude) * 0.5
    region.span.latitudeDelta = fabs(topLeftCoord.latitude - bottomRightCoord.latitude) * 1.4
    region.span.longitudeDelta = fabs(bottomRightCoord.longitude - topLeftCoord.longitude) * 1.4
    region = aMapView.regionThatFits(region)
    myMap.setRegion(region, animated: true)
}

function redir(data) {_x000D_
  document.getElementById('redirect').innerHTML = '<form style="display:none;" position="absolute" method="post" action="location.php"><input id="redirbtn" type="submit" name="value" value=' + data + '></form>';_x000D_
  document.getElementById('redirbtn').click();_x000D_
}

<button onclick="redir('dataToBeSent');">Next Page</button>_x000D_
<div id="redirect"></div>

You can use this method which creates a new hidden form whose "data" is sent by "post" to "location.php" when a button[Next Page] is clicked.

Consider this to get a fully unique jar file:

• GroupID - com.companyname.project
• ArtifactId - com-companyname-project
• Package - com.companyname.project

You can use this code:

def is_valid(string):
    words = string.split('_')
    for word in words:
        if not word.istitle():
            return False, word
    return True, words
x="Alpha_beta_Gamma"
assert is_valid(x)==(False,'beta')
x="Alpha_Beta_Gamma"
assert is_valid(x)==(True,['Alpha', 'Beta', 'Gamma'])

This way you know if is valid and what word is wrong

Use " instead of " to escape it.

web.config is an XML file so you should use XML escaping.

connectionString="Server=dbsrv;User ID=myDbUser;Password=somepass"word"

See this forum thread.

Update:

" should work, but as it doesn't, have you tried some of the other string escape sequences for .NET? \" and ""?

Update 2:

Try single quotes for the connectionString:

connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'

Or:

connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'

Update 3:

From MSDN (SqlConnection.ConnectionString Property):

To include values that contain a semicolon, single-quote character, or double-quote character, the value must be enclosed in double quotation marks. If the value contains both a semicolon and a double-quote character, the value can be enclosed in single quotation marks.

So:

connectionString="Server=dbsrv;User ID=myDbUser;Password='somepass"word'"

The issue is not with web.config, but the format of the connection string. In a connection string, if you have a " in a value (of the key-value pair), you need to enclose the value in '. So, while Password=somepass"word does not work, Password='somepass"word' does.

In my point,

border:none is working but not valid w3c standard

so better we can use border:0;

You can't have an array of a generic type. Use List instead.

Here's yet another take on it (only using the test builtin command and its return code):

function is_int() { test "$@" -eq "$@" 2> /dev/null; } 
 
input="-123"
 
if is_int "$input"
then
   echo "Input: ${input}"
   echo "Integer: ${input}"
else
   echo "Not an integer: ${input}"
fi

Since getEntries returns a raw List, it could hold anything.

The warning-free approach is to create a new List<SyndEntry>, then cast each element of the sf.getEntries() result to SyndEntry before adding it to your new list. Collections.checkedList does not do this checking for you—although it would have been possible to implement it to do so.

By doing your own cast up front, you're "complying with the warranty terms" of Java generics: if a ClassCastException is raised, it will be associated with a cast in the source code, not an invisible cast inserted by the compiler.

What are non-recursive mutexes good for?

They are absolutely good when you have to make sure the mutex is unlocked before doing something. This is because pthread_mutex_unlock can guarantee that the mutex is unlocked only if it is non-recursive.

pthread_mutex_t      g_mutex;

void foo()
{
    pthread_mutex_lock(&g_mutex);
    // Do something.
    pthread_mutex_unlock(&g_mutex);

    bar();
}

If g_mutex is non-recursive, the code above is guaranteed to call bar() with the mutex unlocked.

Thus eliminating the possibility of a deadlock in case bar() happens to be an unknown external function which may well do something that may result in another thread trying to acquire the same mutex. Such scenarios are not uncommon in applications built on thread pools, and in distributed applications, where an interprocess call may spawn a new thread without the client programmer even realising that. In all such scenarios it's best to invoke the said external functions only after the lock is released.

If g_mutex was recursive, there would be simply no way to make sure it is unlocked before making a call.

Hope this helps:

If you are generating XML files programatically, you may want to look at the XMLBeans library. Using a command line tool, XMLBeans will automatically generate and package up a set of Java objects based on an XSD. You can then use these objects to build an XML document based on this schema.

It has built-in support for schema validation, and can convert Java objects to an XML document and vice-versa.

Castor and JAXB are other Java libraries that serve a similar purpose to XMLBeans.

Using dependency injection in your constructor makes managing the lifetime of your HttpClient easier - taking the lifetime managemant outside of the code that needs it and making it easily changable at a later date.

My current preference is to create a seperate http client class that inherits from HttpClient once per target endpoint domain and then make it a singleton using dependency injection. public class ExampleHttpClient : HttpClient { ... }

Then I take a constructor dependency on the custom http client in the service classes where I need access to that API. This solves the lifetime problem and has advantages when it comes to connection pooling.

Simply style your Submit button like you would style any other html element. you can target different type of input elements using CSS attribute selector

As an example you could write

input[type=text] {
   /*your styles here.....*/
}
input[type=submit] {
   /*your styles here.....*/
}
textarea{
   /*your styles here.....*/
}

Combine with other selectors

input[type=text]:hover {
   /*your styles here.....*/
}
input[type=submit] > p {
   /*your styles here.....*/
}
....

Here is a working Example

It is to my understanding that you want to embed a video on your site that:

• Is responsive
• Allows both autoplay and loop
• Uses Bootstrap

This Demo Here does just that. You have to place another embed class outside of the object/embed/iframe tag as per the the instructions here - but you're also able to use a video tag instead of the object tag even though it's not specified.

<div align="center" class="embed-responsive embed-responsive-16by9">
    <video autoplay loop class="embed-responsive-item">
        <source src="http://techslides.com/demos/sample-videos/small.mp4" type="video/mp4">
    </video>
</div>

I know only Oracle databases, no other ones, and I can tell that Foreign Keys are essential for maintaining data integrity. Prior to inserting data, a data structure needs to be made, and be made correctlty. When that is done - and thus all primary AND foreign keys are created - the work is done !

Meaning : orphaned rows ? No. Never seen that in my life. Unless a bad programmer forgot the foreign key, or if he implemented that on another level. Both are - in context of Oracle - huge mistakes, which will lead to data duplication, orphan data, and thus : data corruption. I can't imagine a database without FK enforced. It looks like chaos to me. It's a bit like the Unix permission system : imagine that everybody is root. Think of the chaos.

Foreign Keys are essential, just like Primary Keys. It's like saying : what if we removing Primary Keys ? Well, total chaos is going to happen. That's what. You may not move the primary or foreign key responsibility to the programming level, it must be at the data level.

Drawbacks ? Yes, absolutely ! Because on insert, a lot more checks are going to be happening. But, if data integrity is more important than performance, it's a no-brainer. The problem with performance on Oracle is more related to indexes, which come with PK and FK's.

sorted(dict.keys())[-1]

Otherwise, the keys is just an unordered list, and the "last one" is meaningless, and even can be different on various python versions.

Maybe you want to look into OrderedDict.

Use the $locationChangeStart or $locationChangeSuccess events, 3rd parameter:

$scope.$on('$locationChangeStart',function(evt, absNewUrl, absOldUrl) {
   console.log('start', evt, absNewUrl, absOldUrl);
});
$scope.$on('$locationChangeSuccess',function(evt, absNewUrl, absOldUrl) {
   console.log('success', evt, absNewUrl, absOldUrl);
});

Use iloc to access by position (rather than label):

In [11]: df = pd.DataFrame([[1, 2], [3, 4]], ['a', 'b'], ['A', 'B'])

In [12]: df
Out[12]: 
   A  B
a  1  2
b  3  4

In [13]: df.iloc[0]  # first row in a DataFrame
Out[13]: 
A    1
B    2
Name: a, dtype: int64

In [14]: df['A'].iloc[0]  # first item in a Series (Column)
Out[14]: 1

Use below code in your xml file

<ListView 
    android:id="@+id/listView"
    android:layout_width="match_parent"

I got it solved by adding "-lc++" in Other Linker Flags in Build Settings.

I had the same problem on OSX OpenSSL 1.0.1i from Macports, and also had to specify CApath as a workaround (and as mentioned in the Ubuntu bug report, even an invalid CApath will make openssl look in the default directory). Interestingly, connecting to the same server using PHP's openssl functions (as used in PHPMailer 5) worked fine.

Just type your desired drive initial in the command line and press enter

Like if you want to go L:\\ drive, Just type L: or l:

ZeroMQ is really with zero queues! It is a really mistake! It does not hav queues, topics, persistence, nothing! It is only a middleware for sockets API. If it is what you are looking cool! otherwise forget it! it is not like activeMQ or rabbitmq.

It may be overkill but you can try this:

// Form calling named route with hidden token field added.

<form method="POST" action="{{ route('foo') }}" >
    @csrf
    <input type="hidden" name="_token" value="{!! csrf_token() !!}">
    <input type="text" name="name"/><br/>
    <input type="submit" value="Add"/>
</form>

// Named Route

Route::post('/foo', function () {
    return 'bar';
})->name('foo');

// Add this within the <head></head> block:

<meta name="_token" content="{!! csrf_token() !!}" />

I did test it on my local using Homestead on Laravel 5.7 which was was fresh install using Laravel Installer 2.0.1 and it worked. What is your environment?

Theory: I wonder if that has something to do with blade rendering html tags with {{ }} vs. {!! !!} on your environment or how you are serving it (eg. php artisan serve). What makes me think that is line 335 of /vendor/laravel/framework/src/illuminate/Foundation/helpers.php should render the same line manually typed out above.

I know it's an old thread I worked with above answer and had to add:

header('Access-Control-Allow-Methods: GET, POST, PUT');

So my header looks like:

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
header('Access-Control-Allow-Methods: GET, POST, PUT');

And the problem was fixed.

If you're using IPython, you can simply run:

%load path/to/your/file.py

See http://ipython.org/ipython-doc/rel-1.1.0/interactive/tutorial.html

Strictly stated you must check all of the following: defined, not empty AND not None.

For "normal" variables it makes a difference if defined and set or not set. See foo and bar in the example below. Both are defined but only foo is set.

On the other side registered variables are set to the result of the running command and vary from module to module. They are mostly json structures. You probably must check the subelement you're interested in. See xyz and xyz.msg in the example below:

cat > test.yml <<EOF
- hosts: 127.0.0.1

  vars:
    foo: ""          # foo is defined and foo == '' and foo != None
    bar:             # bar is defined and bar != '' and bar == None

  tasks:

  - debug:
      msg : ""
    register: xyz    # xyz is defined and xyz != '' and xyz != None
                     # xyz.msg is defined and xyz.msg == '' and xyz.msg != None

  - debug:
      msg: "foo is defined and foo == '' and foo != None"
    when: foo is defined and foo == '' and foo != None

  - debug:
      msg: "bar is defined and bar != '' and bar == None"
    when: bar is defined and bar != '' and bar == None

  - debug:
      msg: "xyz is defined and xyz != '' and xyz != None"
    when: xyz is defined and xyz != '' and xyz != None
  - debug:
      msg: "{{ xyz }}"

  - debug:
      msg: "xyz.msg is defined and xyz.msg == '' and xyz.msg != None"
    when: xyz.msg is defined and xyz.msg == '' and xyz.msg != None
  - debug:
      msg: "{{ xyz.msg }}"
EOF
ansible-playbook -v test.yml

This should allow you to check if element with id='remember' is 'checked'

if (document.getElementById('remember').is(':checked')

Got it :D

function getContextPath() {
   return window.location.pathname.substring(0, window.location.pathname.indexOf("/",2));
}
alert(getContextPath());

Important note: Does only work for the "root" context path. Does not work with "subfolders", or if context path has a slash ("/") in it.

Ok it is late but in case you or someone else still want to you use a switch or simply have a better understanding of how the switch statement works.

What was wrong is that your switch expression should match in strict comparison one of your case expression. If there is no match it will look for a default. You can still use your expression in your case with the && operator that makes Short-circuit evaluation.

Ok you already know all that. For matching the strict comparison you should add at the end of all your case expression && cnt.

Like follow:

switch(mySwitchExpression)
case customEpression && mySwitchExpression: StatementList
.
.
.
default:StatementList

var cnt = $("#div1 p").length;
alert(cnt);
switch (cnt) {
case (cnt >= 10 && cnt <= 20 && cnt):
    alert('10');
    break;
case (cnt >= 21 && cnt <= 30 && cnt):
    alert('21');
    break;
case (cnt >= 31 && cnt <= 40 && cnt):
    alert('31');
    break;
default:
    alert('>41');
}

It is possible to connect to the database without specifying a password. Once you've done that you can then reset the passwords. I'm assuming that you've installed the database on your machine; if not you'll first need to connect to the machine the database is running on.

1. Ensure your user account is a member of the dba group. How you do this depends on what OS you are running.

2. Enter sqlplus / as sysdba in a Command Prompt/shell/Terminal window as appropriate. This should log you in to the database as SYS.

3. Once you're logged in, you can then enter

   alter user SYS identified by "newpassword";
   

   to reset the SYS password, and similarly for SYSTEM.

(Note: I haven't tried any of this on Oracle 12c; I'm assuming they haven't changed things since Oracle 11g.)

bool EndsWith(const std::string& data, const std::string& suffix)
{
    return data.find(suffix, data.size() - suffix.size()) != string::npos;
}

Tests

#include <iostream>
int main()
{
   cout << EndsWith(u8"o!hello!1", u8"o!") << endl; 
   cout << EndsWith(u8"o!hello!", u8"o!") << endl; 
   cout << EndsWith(u8"hello!", u8"o!") << endl; 
   cout << EndsWith(u8"o!hello!o!", u8"o!") << endl; 
   return 0;
}

Output

The Application.Volatile doesn't work for recalculating a formula with my own function inside. I use the following function: Application.CalculateFull

I might consider using a dict and re.sub for something like this:

import re
repldict = {'zero':'0', 'one':'1' ,'temp':'bob','garage':'nothing'}
def replfunc(match):
    return repldict[match.group(0)]

regex = re.compile('|'.join(re.escape(x) for x in repldict))
with open('file.txt') as fin, open('fout.txt','w') as fout:
    for line in fin:
        fout.write(regex.sub(replfunc,line))

This has a slight advantage to replace in that it is a bit more robust to overlapping matches.

I really hate these linq expressions, this is why SQL exists:

select isnull(fn.id, ln.id) as id, fn.firstname, ln.lastname
   from firstnames fn
   full join lastnames ln on ln.id=fn.id

Create this as sql view in database and import it as entity.

Of course, (distinct) union of left and right joins will make it too, but it is stupid.

Another option, especially if you're already using UnderscoreJS, would be:

_.last([1, 2, 3, 4]); // Will return 4

No, but you could cast the whole expression rather than the sub-components of that expression. Actually, that probably makes it less readable in this case.

If your server is Ubuntu and Apache version is 2.4

Server version: Apache/2.4.29 (Ubuntu)

Then you export variables in "/etc/apache2/envvars" location.

Just like this below line, you need to add an extra line in "/etc/apache2/envvars" export GOROOT=/usr/local/go

You can't have a link to SCSS File in your HTML page.You have to compile it down to CSS First. No there are lots of video tutorials you might want to check out. Lynda provides great video tutorials on SASS. there are also free screencasts you can google...

For official documentation visit this site http://sass-lang.com/documentation/file.SASS_REFERENCE.html And why have you chosen notepad to write Sass?? you can easily download some free text editors for better code handling.

Try this:

import pickle

a = {'hello': 'world'}

with open('filename.pickle', 'wb') as handle:
    pickle.dump(a, handle, protocol=pickle.HIGHEST_PROTOCOL)

with open('filename.pickle', 'rb') as handle:
    b = pickle.load(handle)

print a == b

This also happens to me when I try to install the opencv-python package:

I can fix it with command line

python3 -m pip install {name of package} --user

When I try to install the said package, the command becomes:

python3 -m pip install opencv-python --user

Resulting in this:

Quoting php.net:

On Windows, both slash (/) and backslash () are used as directory separator character. In other environments, it is the forward slash (/).

Based on this info and expanding from arzzzen answer this should work on both Windows and Nix* systems:

<?php

if (basename(str_replace('\\', '/', get_class($object))) == 'Name') {
    // ... do this ...
}

Note: I did a benchmark of ReflectionClass against basename+str_replace+get_class and using reflection is roughly 20% faster than using the basename approach, but YMMV.

I know the OP was looking for a CSS solution but it is simple to achieve using jQuery. In my case I needed to find the <ul> parent tag for a <span> tag contained in the child <li>. jQuery has the :has selector so it's possible to identify a parent by the children it contains:

$("ul:has(#someId)")

will select the ul element that has a child element with id someId. Or to answer the original question, something like the following should do the trick (untested):

$("li:has(.active)")

All this peace of code put into *.bat file and run all at once:

My code for creating user in oracle. crate_drop_user.sql file

drop user "USER" cascade;
DROP TABLESPACE "USER";

CREATE TABLESPACE USER DATAFILE 'D:\ORA_DATA\ORA10\USER.ORA' SIZE 10M REUSE 
    AUTOEXTEND 
    ON NEXT  5M  EXTENT MANAGEMENT LOCAL 
    SEGMENT SPACE MANAGEMENT  AUTO
/ 

CREATE  TEMPORARY TABLESPACE "USER_TEMP" TEMPFILE 
    'D:\ORA_DATA\ORA10\USER_TEMP.ORA' SIZE 10M REUSE AUTOEXTEND
    ON NEXT  5M  EXTENT MANAGEMENT LOCAL 
    UNIFORM SIZE 1M    
/

CREATE USER "USER"  PROFILE "DEFAULT" 
    IDENTIFIED BY "user_password" DEFAULT TABLESPACE "USER" 
    TEMPORARY TABLESPACE "USER_TEMP" 
/    

alter user USER quota unlimited on "USER";

GRANT CREATE PROCEDURE TO "USER";
GRANT CREATE PUBLIC SYNONYM TO "USER";
GRANT CREATE SEQUENCE TO "USER";
GRANT CREATE SNAPSHOT TO "USER";
GRANT CREATE SYNONYM TO "USER";
GRANT CREATE TABLE TO "USER";
GRANT CREATE TRIGGER TO "USER";
GRANT CREATE VIEW TO "USER";
GRANT "CONNECT" TO "USER";
GRANT SELECT ANY DICTIONARY to "USER";
GRANT CREATE TYPE TO "USER";

create file import.bat and put this lines in it:

SQLPLUS SYSTEM/systempassword@ORA_alias @"crate_drop_user.SQL"
IMP SYSTEM/systempassword@ORA_alias FILE=user.DMP FROMUSER=user TOUSER=user GRANTS=Y log =user.log

Be carefull if you will import from one user to another. For example if you have user named user1 and you will import to user2 you may lost all grants , so you have to recreate it.

Good luck, Ivan

function getStyle(className) {
    document.styleSheets.item("menu").cssRules.item(className).cssText;
}
getStyle('.test')

Note : "menu" is an element ID which you have applied CSS. "className" a css class name which we need to get its text.

Windows -> Preferences -> Server -> Runtime Environment -> Delete all Apache servers available. Add the same. Now run your application on server. Its done :)

You could (but you shouldn't) use reflection for the job:

import java.lang.reflect.Field;

public class Outer {
    public class Inner {
    }

    public static void main(String[] args) throws Exception {

        // Create the inner instance
        Inner inner = new Outer().new Inner();

        // Get the implicit reference from the inner to the outer instance
        // ... make it accessible, as it has default visibility
        Field field = Inner.class.getDeclaredField("this$0");
        field.setAccessible(true);

        // Dereference and cast it
        Outer outer = (Outer) field.get(inner);
        System.out.println(outer);
    }
}

Of course, the name of the implicit reference is utterly unreliable, so as I said, you shouldn't :-)

A simple fix would be to use the following CSS property.

input[type=radio]:checked{
    background: \*colour*\;
    border-radius: 15px;
    border: 4px solid #dfdfdf;
}

I had (have) a similar problem in a Java application. I wrote a JDBC driver wrapper around the Oracle driver so all output is sent to a log file.

I know it has been quite sometime that you asked this but, if someone else needs, I did what was saying here " How to upload a project to Github " and after the top answer of this question right here. And after was the top answer was saying here "git error: failed to push some refs to" I don't know what exactly made everything work. But now is working.

I had the same problem, and have not been able to get Eclipse in Windows 7 to recognise the device. The device is correctly configured, Windows 7 recognises it on the USB port, and I edited the Run settings in Eclipse to prompt for a device, and it is just not there.

I ran it with the following steps:

• Connect the device to the computer with USB.
• Ensure the device is not locked (ie. timed out in the UI). I have to keep unlocking it while I'm working.
• Wait for Windows to recognise the USB device, and when the autoplay menu comes up select Open device to view files. It should open up the file system in the device, in Explorer.
• In Explorer go to the Eclipse workspace and find the apk file from the build (eg. MyFirstApp.apk)
• Copy the apk file to the Downloads directory on the device
• On the device, use the My Files app (or similar) to open the Downloads directory.
• Click the downloaded file (My First App.apk) and Android offers to install it
• Select install
• The app is now in the installed Apps. Run it.

A second method is to mail the apk file to the device and then download and install it. (Credits to a post on SO which I can't find now).

A third method is to use DropBox. This requires installation of DropBox on the PC and on the device (from the play store) but once both are set up it runs very smoothly. Just share a DropBox folder between the two devices, and then drop the APK into that folder on the PC, and open it on the device. With this method you don't need a USB connection, and can also install the APK on multiple devices. It also assists the management of multiple development versions (by making a separate sub-folder for each version).

Here is the solution just copy your SDK Manager.exe file at the root folder of your android studio's installation, Sync your project and cheers... here is the link for details. running Android Studio on Windows 7 fails, no Android SDK found

What Every Computer Scientist Should Know About Floating-Point Arithmetic

Floating-point numbers cannot represent all the numbers. In particular, 2.51 cannot be represented by a floating-point number, and is represented by a number very close to it:

>>> print "%.16f" % 2.51
2.5099999999999998
>>> 2.51*100
250.99999999999997
>>> 4.02*100
401.99999999999994

If you use int, which truncates the numbers, you get:

250
401

Have a look at the Decimal type.

How about:

Random generator = new Random();
int i = 10 - generator.nextInt(10);

use this

self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"Default"]];

The DataTable has a collection .Rows of DataRow elements.

Each DataRow corresponds to one row in your database, and contains a collection of columns.

In order to access a single value, do something like this:

 foreach(DataRow row in YourDataTable.Rows)
 { 
     string name = row["name"].ToString();
     string description = row["description"].ToString();
     string icoFileName = row["iconFile"].ToString();
     string installScript = row["installScript"].ToString();
 }

my_var = (int)my_var;

As simple as that. Basically you don't need it if the variable is int.

There is no need to decompile Applet.class. The public Java API classes sourcecode comes with the JDK (if you choose to install it), and is better readable than decompiled bytecode. You can find compressed in src.zip (located in your JDK installation folder).

There is no limit to the input of md5 that I know of. Some implementations require the entire input to be loaded into memory before passing it into the md5 function (i.e., the implementation acts on a block of memory, not on a stream), but this is not a limitation of the algorithm itself. The output is always 128 bits. Note that md5 is not an encryption algorithm, but a cryptographic hash. This means that you can use it to verify the integrity of a chunk of data, but you cannot reverse the hashing. Also note that md5 is considered broken, so you shouldn't use it for anything security-related (it's still fine to verify the integrity of downloaded files and such).

Your problem is that you have 64-bit eclipse running but you have 32 bit JRE.So please download JRE for 64 bit windows and let it install on the default location. Finally add that path till bin in your PATH variable. Try it should work.

You really want to use at. It is exactly made for this purpose.

echo /usr/bin/the_command options | at now + 1 day

However if you don't have at, or your hosting company doesn't provide access to it, you could make a self-deleting cron entry.

Sadly, this will remove all your cron entries. However, if you only have one, this is fine.

0 0 2 12 * crontab -r ; /home/adm/bin/the_command options

The command crontab -r removes your crontab entry. Luckily the rest of the command line will still execute.

WARNING: This is dangerous! It removes ALL cron entries. If you have many, this will remove them all, not just the one that has the "crontab -r" line!

The solution of @user8178061 worked well but I did it with some modifications for my version wich is python3.7 with Ubuntu

I replaced the apt_pkg.cpython-3m-i386-linux-gnu.so with apt_pkg.cpython-36m-x86_64-linux-gnu.so

Here the two commands to execute:

cd /usr/lib/python3/dist-packages

sudo cp apt_pkg.cpython-36m-x86_64-linux-gnu.so apt_pkg.so

A proper solution is using a css class instead of writing src in js file. For example instead of using:

$(this).css("background", "url('../Images/filters_collapse.jpg')");

use:

$(this).addClass("xxx");

and in a css file that is loaded in the page write:

.xxx {
  background-image:url('../Images/filters_collapse.jpg');
}

Upon adding few bits and pieces from all the solutions on this page, I was able to get something like this(for someone who need to use it right away). parameters to the function are df(input dataframe) and key(column that has delimiter separated string). Just replace with your delimiter if that is different to semicolon ";".

def split_df_rows_for_semicolon_separated_key(key, df):
    df=df.set_index(df.columns.drop(key,1).tolist())[key].str.split(';', expand=True).stack().reset_index().rename(columns={0:key}).loc[:, df.columns]
    df=df[df[key] != '']
    return df

I had a requirement of using various python utilities (range, string, etc.) on the command line and had written the tool pyfunc specifically for that. You can use it to enrich you command line usage experience:

 $ pyfunc -m range -a 1 7 2
 1
 3
 5

 $ pyfunc -m string.upper -a test
 TEST

 $ pyfunc -m string.replace -a 'analyze what' 'what' 'this'
 analyze this

This is so confusing. All developers I asked didn't appreciate this default behavior.

I use cmd + P to open project files.

when you want to get all image from folder then use glob() built in function which help to get all image . But when you get all then sometime need to check that all is valid so in this case this code help you. this code will also check that it is image

  $all_files = glob("mytheme/images/myimages/*.*");
  for ($i=0; $i<count($all_files); $i++)
    {
      $image_name = $all_files[$i];
      $supported_format = array('gif','jpg','jpeg','png');
      $ext = strtolower(pathinfo($image_name, PATHINFO_EXTENSION));
      if (in_array($ext, $supported_format))
          {
            echo '<img src="'.$image_name .'" alt="'.$image_name.'" />'."<br /><br />";
          } else {
              continue;
          }
    }

PHP Manual

You can open multiple windows on single click... Try this..

<a href="http://--" 
     onclick=" window.open('http://--','','width=700,height=700'); 
               window.open('http://--','','width=700,height=500'); ..// add more"
               >Click Here</a>`

You can assign the DataFrame to a filtered version of itself:

df = df[df.score > 50]

This is faster than drop:

%%timeit
test = pd.DataFrame({'x': np.random.randn(int(1e6))})
test = test[test.x < 0]
# 54.5 ms ± 2.02 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

%%timeit
test = pd.DataFrame({'x': np.random.randn(int(1e6))})
test.drop(test[test.x > 0].index, inplace=True)
# 201 ms ± 17.9 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

%%timeit
test = pd.DataFrame({'x': np.random.randn(int(1e6))})
test = test.drop(test[test.x > 0].index)
# 194 ms ± 7.03 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

function Hello() {
    alert(Hello.caller);
}

Django 1.10 (release notes) added the is and is not comparison operators to the if tag. This change makes identity testing in a template pretty straightforward.

In[2]: from django.template import Context, Template

In[3]: context = Context({"somevar": False, "zero": 0})

In[4]: compare_false = Template("{% if somevar is False %}is false{% endif %}")
In[5]: compare_false.render(context)
Out[5]: u'is false'

In[6]: compare_zero = Template("{% if zero is not False %}not false{% endif %}")
In[7]: compare_zero.render(context)
Out[7]: u'not false'

If You are using an older Django then as of version 1.5 (release notes) the template engine interprets True, False and None as the corresponding Python objects.

In[2]: from django.template import Context, Template

In[3]: context = Context({"is_true": True, "is_false": False, 
                          "is_none": None, "zero": 0})

In[4]: compare_true = Template("{% if is_true == True %}true{% endif %}")
In[5]: compare_true.render(context)
Out[5]: u'true'

In[6]: compare_false = Template("{% if is_false == False %}false{% endif %}")
In[7]: compare_false.render(context)
Out[7]: u'false'

In[8]: compare_none = Template("{% if is_none == None %}none{% endif %}")
In[9]: compare_none.render(context)
Out[9]: u'none'

Although it does not work the way one might expect.

In[10]: compare_zero = Template("{% if zero == False %}0 == False{% endif %}")
In[11]: compare_zero.render(context)
Out[11]: u'0 == False'

Put the values you need someplace where the other script can retrieve them, like a hidden input, and then pull those values from their container when you initialize your new script. You could even put all your params as a JSON string into one hidden field.

I solved this problem by keying the array with the ID. It's simpler and possibly faster for this scenario where the ID is what you're looking for.

[420] => stdClass Object
        (
            [name] => Mary
         )

[10957] => stdClass Object
        (
            [name] => Blah
         )
...

Now I can directly address the array:

$array[$v]->name = ...

Or, if I want to verify the existence of an ID:

if (array_key_exists($v, $array)) { ...

The other answers are helpful, but the JSON in your question isn't valid. I have formatted it to make it clearer below, note the missing single quote on line 24.

There are a lot of great articles on how to manipulate objects in Javascript (whether using Node JS or a browser). I suggest here is a good place to start: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Working_with_Objects

In Swift, appending strings is as easy as:

let stringA = "this is a string"
let stringB = "this is also a string"
let stringC = stringA + stringB

Or you can use string interpolation.

let stringC = "\(stringA) \(stringB)"

Notice there will now be whitespace between them.

Note: I see the other answers are using var a lot. The strings aren't changing and therefore should be declared using let. I know this is a small exercise, but it's good to get into the habit of best practices. Especially because that's a big feature of Swift.

I think I got it at last by doing some manual transformations with the data before visualization:

d <- diamonds
# computing logarithm of prices
d$price <- log10(d$price)

And work out a formatter to later compute 'back' the logarithmic data:

formatBack <- function(x) 10^x 
# or with special formatter (here: "dollar")
formatBack <- function(x) paste(round(10^x, 2), "$", sep=' ') 

And draw the plot with given formatter:

m <- ggplot(d, aes(y = price, x = color))
m + geom_boxplot() + scale_y_continuous(formatter='formatBack')

Sorry to the community to bother you with a question I could have solved before! The funny part is: I was working hard to make this plot work a month ago but did not succeed. After asking here, I got it.

Anyway, thanks to @DWin for motivation!

It's not an ideal solution but here's a quick and dirty example that shows how you could store login info in the PHP code:

<?php
session_start();

$userinfo = array(
                'user1'=>'password1',
                'user2'=>'password2'
                );

if(isset($_GET['logout'])) {
    $_SESSION['username'] = '';
    header('Location:  ' . $_SERVER['PHP_SELF']);
}

if(isset($_POST['username'])) {
    if($userinfo[$_POST['username']] == $_POST['password']) {
        $_SESSION['username'] = $_POST['username'];
    }else {
        //Invalid Login
    }
}
?>

My solution was to create all the launch images.

Then I set the Launch Images Source to the LaunchImage asset, and leave launch screen file blank.

Finally if the project does not have a Launch Screen.xib, then add that file and leave it as is.

Short answer:

As written in xsd:

<xs:attribute name="minOccurs" type="xs:nonNegativeInteger" use="optional" default="1"/>
<xs:attribute name="maxOccurs" type="xs:allNNI" use="optional" default="1"/>

If you provide an attribute with number, then the number is boundary. Otherwise attribute should appear exactly once.

Here is Apple's documentation:

Technical Q&A QA1760

It says there are two things that you must get right:

1. Add armv6 to the Architecture build settings
2. Set Build Active Architecture Only to No.

If this still doesn't help you, double check that you are really changing the architecture build settings for the right build configuration – I wasted half an hour fiddling with the wrong one and wondering why it didn't work...

Select Edit Scheme... in the Product menu, click the "Archive" scheme in the left list and check the Build Configuration. Change the value if it was not what you expected.

Where a is the slice, and i is the index of the element you want to delete:

a = append(a[:i], a[i+1:]...)

... is syntax for variadic arguments in Go.

Basically, when defining a function it puts all the arguments that you pass into one slice of that type. By doing that, you can pass as many arguments as you want (for example, fmt.Println can take as many arguments as you want).

Now, when calling a function, ... does the opposite: it unpacks a slice and passes them as separate arguments to a variadic function.

So what this line does:

a = append(a[:0], a[1:]...)

is essentially:

a = append(a[:0], a[1], a[2])

Now, you may be wondering, why not just do

a = append(a[1:]...)

Well, the function definition of append is

func append(slice []Type, elems ...Type) []Type

So the first argument has to be a slice of the correct type, the second argument is the variadic, so we pass in an empty slice, and then unpack the rest of the slice to fill in the arguments.

My solution is based on the TechNet article Fun Things You Can Do With the Get-ChildItem Cmdlet.

Get-ChildItem C:\foo | Where-Object {$_.mode -match "d"}

I used it in my script, and it works well.

The awk is ok. I'm guessing the file is from a windows system and has a CR (^m ascii 0x0d) on the end of the line.

This will cause the cursor to go to the start of the line after $2.

Use dos2unix or vi with :se ff=unix to get rid of the CRs.

I had a similar error but with different context when I uploaded a *.p file to Google Drive. I tried to use it later in a Google Colab session, and got this error:

    1 with open("/tmp/train.p", mode='rb') as training_data:
----> 2     train = pickle.load(training_data)
UnpicklingError: invalid load key, '<'.

I solved it by compressing the file, upload it and then unzip on the session. It looks like the pickle file is not saved correctly when you upload/download it so it gets corrupted.

The answer has been copied from this tutorial I wrote at LearnOpenCV.com explaining various parameters of SimpleBlobDetector. You can find additional details about the parameters in the tutorial.

Use String#toLowerCase() or String#equalsIgnoreCase() methods

Some examples:

    String abc    = "Abc".toLowerCase();
    boolean isAbc = "Abc".equalsIgnoreCase("ABC");

You can use Internet Explorer to browse folders and files together in tree. It is a file explorer in Favorites Window. You just need replace "favorites folder" to folder which you want see as a root folder

I went through the answers above. The "as_matrix()" method works but its obsolete now. For me, What worked was ".to_numpy()".

This returns a multidimensional array. I'll prefer using this method if you're reading data from excel sheet and you need to access data from any index. Hope this helps :)

Width value doesn't take into account border or padding:

http://www.htmldog.com/reference/cssproperties/width/

You get 2px of padding in each side, plus 1px of border in each side.
100% + 2*(2px +1px) = 100% + 6px, which is more than the 100% child-content the parent td has.

You have the option of:

• Either setting box-sizing: border-box; as per @pricco's answer;
• Or using 0 margin and padding (avoiding the extra size).

After you commit your object into the db the object receives a value in its ID field.

So:

myObject.Field1 = "value";

// Db is the datacontext
db.MyObjects.InsertOnSubmit(myObject);
db.SubmitChanges();

// You can retrieve the id from the object
int id = myObject.ID;

keep in mind that avoiding text scaling is the main reason responsive layouts exist. the entire logic behind responsive sites is to create functional layouts that effectively display your content so its easily readable and usable on multiple screen sizes.

Although It is necessary to scale text in some cases, be careful not to miniaturise your site and miss the point.

heres an example anyway.

@media(min-width:1200px){

    h1 {font-size:34px}

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

    h1 {font-size:32px}

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

    h1 {font-size:28px}

}
@media(max-width:767px){

    h1 {font-size:26px}

}

Also keep in mind the 480 viewport has been dropped in bootstrap 3.

For new gTLDs

/^((?!-)[\p{L}\p{N}-]+(?<!-)\.)+[\p{L}\p{N}]{2,}$/iu

I came across this method and I use it to make div IDs the slug name inside the loop:

<?php $slug = basename( get_permalink() ); echo $slug;?>

val.ToString("".PadLeft(length, '0'))

Just to update, following iOS 13, we now have SceneDelegates. So one might choose to put the desired tab selection in SceneDelegate.swift as follows:

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?

    func scene(_ scene: UIScene, 
               willConnectTo session: UISceneSession, 
               options connectionOptions: UIScene.ConnectionOptions) {

        guard let _ = (scene as? UIWindowScene) else { return }

        if let tabBarController = self.window!.rootViewController as? UITabBarController {
            tabBarController.selectedIndex = 1
        }

    }

Your life will be much easier if you can save a List as the value instead of an array in that Map.

You can use matching groups:

p = re.compile('name (.*) is valid')

e.g.

>>> import re
>>> p = re.compile('name (.*) is valid')
>>> s = """
... someline abc
... someother line
... name my_user_name is valid
... some more lines"""
>>> p.findall(s)
['my_user_name']

Here I use re.findall rather than re.search to get all instances of my_user_name. Using re.search, you'd need to get the data from the group on the match object:

>>> p.search(s)   #gives a match object or None if no match is found
<_sre.SRE_Match object at 0xf5c60>
>>> p.search(s).group() #entire string that matched
'name my_user_name is valid'
>>> p.search(s).group(1) #first group that match in the string that matched
'my_user_name'

As mentioned in the comments, you might want to make your regex non-greedy:

p = re.compile('name (.*?) is valid')

to only pick up the stuff between 'name ' and the next ' is valid' (rather than allowing your regex to pick up other ' is valid' in your group.

I agree with Jim Blizard. The database is not the part of your technology stack that should send emails. For example, what if you send an email but then roll back the change that triggered that email? You can't take the email back.

It's better to send the email in your application code layer, after your app has confirmed that the SQL change was made successfully and committed.

The include tag

The <include> tag lets you to divide your layout into multiple files: it helps dealing with complex or overlong user interface.

Let's suppose you split your complex layout using two include files as follows:

top_level_activity.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file -->
    <include layout="@layout/include1.xml" />

    <!-- Second include file -->
    <include layout="@layout/include2.xml" />

</LinearLayout>

Then you need to write include1.xml and include2.xml.

Keep in mind that the xml from the include files is simply dumped in your top_level_activity layout at rendering time (pretty much like the #INCLUDE macro for C).

The include files are plain jane layout xml.

include1.xml:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/textView1"
    android:text="First include"
    android:textAppearance="?android:attr/textAppearanceMedium"/>

... and include2.xml:

<?xml version="1.0" encoding="utf-8"?>
<Button xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/button1"
    android:text="Button" />

See? Nothing fancy. Note that you still have to declare the android namespace with xmlns:android="http://schemas.android.com/apk/res/android.

So the rendered version of top_level_activity.xml is:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file -->
    <TextView
        android:id="@+id/textView1"
        android:text="First include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <!-- Second include file -->
    <Button
        android:id="@+id/button1"
        android:text="Button" />


</LinearLayout>

In your java code, all this is transparent: findViewById(R.id.textView1) in your activity class returns the correct widget ( even if that widget was declared in a xml file different from the activity layout).

And the cherry on top: the visual editor handles the thing swimmingly. The top level layout is rendered with the xml included.

The plot thickens

As an include file is a classic layout xml file, it means that it must have one top element. So in case your file needs to include more than one widget, you would have to use a layout.

Let's say that include1.xml has now two TextView: a layout has to be declared. Let's choose a LinearLayout.

include1.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout2" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:text="Second include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <TextView
        android:id="@+id/textView2"
        android:text="More text"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

</LinearLayout>

The top_level_activity.xml will be rendered as:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file -->
    <LinearLayout 
        android:id="@+id/layout2" 
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

       <TextView
            android:id="@+id/textView1"
            android:text="Second include"
            android:textAppearance="?android:attr/textAppearanceMedium"/>

       <TextView
            android:id="@+id/textView2"
            android:text="More text"
            android:textAppearance="?android:attr/textAppearanceMedium"/>

   </LinearLayout>

     <!-- Second include file -->
   <Button
        android:id="@+id/button1"
        android:text="Button" />

</LinearLayout>

But wait the two levels of LinearLayout are redundant!

Indeed, the two nested LinearLayout serve no purpose as the two TextView could be included under layout1for exactly the same rendering.

So what can we do?

Enter the merge tag

The <merge> tag is just a dummy tag that provides a top level element to deal with this kind of redundancy issues.

Now include1.xml becomes:

<merge xmlns:android="http://schemas.android.com/apk/res/android">

    <TextView
        android:id="@+id/textView1"
        android:text="Second include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <TextView
        android:id="@+id/textView2"
        android:text="More text"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

</merge>

and now top_level_activity.xml is rendered as:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file --> 
    <TextView
        android:id="@+id/textView1"
        android:text="Second include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <TextView
        android:id="@+id/textView2"
        android:text="More text"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <!-- Second include file -->
    <Button
        android:id="@+id/button1"
        android:text="Button" />

</LinearLayout>

You saved one hierarchy level, avoid one useless view: Romain Guy sleeps better already.

Aren't you happier now?

There is no fully compatible alternative in JavaScript as it posses an unsafe security issue to allow client-side code to become aware of the logged in user.

That said, the following code would allow you to get the logged in username, but it will only work on Windows, and only within Internet Explorer, as it makes use of ActiveX. Also Internet Explorer will most likely display a popup alerting you to the potential security problems associated with using this code, which won't exactly help usability.

<!doctype html>
<html>
<head>
    <title>Windows Username</title>
</head>
<body>
<script type="text/javascript">
    var WinNetwork = new ActiveXObject("WScript.Network");
    alert(WinNetwork.UserName); 
</script>
</body>
</html>

As Surreal Dreams suggested you could use AJAX to call a server-side method that serves back the username, or render the HTML with a hidden input with a value of the logged in user, for e.g.

(ASP.NET MVC 3 syntax)

<input id="username" type="hidden" value="@User.Identity.Name" />

$('div#someID').datepicker({
   onSelect: function(dateText, inst) { alert(dateText); }
});

you must bind it to input element only

For those coming here to find the item count of something that is already a jQuery object:
.length is what you are looking for:

Example:

len = $('#divID').length;
alert(len);

For MySQL:

SELECT *
FROM permlog
ORDER BY id DESC
LIMIT 1

You want to sort the rows from highest to lowest id, hence the ORDER BY id DESC. Then you just want the first one so LIMIT 1:

The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement.
[...]
With one argument, the value specifies the number of rows to return from the beginning of the result set

??Device Orientation != Interface Orientation??

Swift 5.* iOS14 and below

You should really make a difference between:

• Device Orientation => Indicates the orientation of the physical device
• Interface Orientation => Indicates the orientation of the interface displayed on the screen

There are many scenarios where those 2 values are mismatching such as:

• When you lock your screen orientation
• When you have your device flat

In most cases you would want to use the interface orientation and you can get it via the window:

private var windowInterfaceOrientation: UIInterfaceOrientation? {
    return UIApplication.shared.windows.first?.windowScene?.interfaceOrientation
}

In case you also want to support < iOS 13 (such as iOS 12) you would do the following:

private var windowInterfaceOrientation: UIInterfaceOrientation? {
    if #available(iOS 13.0, *) {
        return UIApplication.shared.windows.first?.windowScene?.interfaceOrientation
    } else {
        return UIApplication.shared.statusBarOrientation
    }
}

Now you need to define where to react to the window interface orientation change. There are multiple ways to do that but the optimal solution is to do it within willTransition(to newCollection: UITraitCollection.

This inherited UIViewController method which can be overridden will be trigger every time the interface orientation will be change. Consequently you can do all your modifications in the latter.

Here is a solution example:

class ViewController: UIViewController {
    override func willTransition(to newCollection: UITraitCollection, with coordinator: UIViewControllerTransitionCoordinator) {
        super.willTransition(to: newCollection, with: coordinator)
        
        coordinator.animate(alongsideTransition: { (context) in
            guard let windowInterfaceOrientation = self.windowInterfaceOrientation else { return }
            
            if windowInterfaceOrientation.isLandscape {
                // activate landscape changes
            } else {
                // activate portrait changes
            }
        })
    }
    
    private var windowInterfaceOrientation: UIInterfaceOrientation? {
        return UIApplication.shared.windows.first?.windowScene?.interfaceOrientation
    }
}

By implementing this method you'll then be able to react to any change of orientation to your interface. But keep in mind that it won't be triggered at the opening of the app so you will also have to manually update your interface in viewWillAppear().

I've created a sample project which underlines the difference between device orientation and interface orientation. Additionally it will help you to understand the different behavior depending on which lifecycle step you decide to update your UI.

Feel free to clone and run the following repository: https://github.com/wjosset/ReactToOrientation

javascript:void(0); --> this executes void function and returns undefined. This could have issues with IE. javascript:; --> this does nothing. safest to create dead links. '#' --> this means pointing to same DOM, it will reload the page on click.

Do you by any chance have two PUBLICclass classes in your project, where one is public (the one of which you posted the signature here), and another one which is package visible, and you import the wrong one in your code ?

I always do input prompts, like this:

    <input style="color: #C0C0C0;" value="[email protected]" 
    onfocus="this.value=''; this.style.color='#000000'">

Of course, if your user fills in the field, changes focus and comes back to the field, the field will once again be cleared. If you do it like that, be sure that's what you want. You can make it a one time thing by setting a semaphore, like this:

    <script language = "text/Javascript"> 
    cleared[0] = cleared[1] = cleared[2] = 0; //set a cleared flag for each field
    function clearField(t){                   //declaring the array outside of the
    if(! cleared[t.id]){                      // function makes it static and global
        cleared[t.id] = 1;  // you could use true and false, but that's more typing
        t.value='';         // with more chance of typos
        t.style.color='#000000';
        }
    }
    </script>

Your <input> field then looks like this:

    <input id = 0; style="color: #C0C0C0;" value="[email protected]" 
    onfocus=clearField(this)>

Swift 3.0

Through a small abstraction https://github.com/daltoniam/swiftHTTP

Example

    do {
        let opt = try HTTP.GET("https://google.com")
        opt.start { response in
            if let err = response.error {
                print("error: \(err.localizedDescription)")
                return //also notify app of failure as needed
            }
            print("opt finished: \(response.description)")
            //print("data is: \(response.data)") access the response of the data with response.data
        }
    } catch let error {
        print("got an error creating the request: \(error)")
    }

LENGTH() returns the length of the string measured in bytes.
CHAR_LENGTH() returns the length of the string measured in characters.

This is especially relevant for Unicode, in which most characters are encoded in two bytes. Or UTF-8, where the number of bytes varies. For example:

select length(_utf8 '€'), char_length(_utf8 '€')
--> 3, 1

As you can see the Euro sign occupies 3 bytes (it's encoded as 0xE282AC in UTF-8) even though it's only one character.

Add a "User-Agent" header to your request.

Some servers attempt to block spidering programs and scrapers from accessing their server because, in earlier days, requests did not send a user agent header.

You can either try to set a custom user agent value or use some value that identifies a Browser like "Mozilla/5.0 Firefox/26.0"

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();

headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("user-agent", "Mozilla/5.0 Firefox/26.0");
headers.set("user-key", "your-password-123"); // optional - in case you auth in headers
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
ResponseEntity<Game[]> respEntity = restTemplate.exchange(url, HttpMethod.GET, entity, Game[].class);

logger.info(respEntity.toString());

Just put the full directory location in the File object.

File file = new File("z:\\results.txt");

I had the same issue, and found a fix as below:

$('.yourModalClassOr#ID').on('shown.bs.modal', function (e) {
    $(' yourModalClassOr#ID ').css("max-height", $(window).height());
    $(' yourModalClassOr#ID ').css("overflow-y", "scroll");          /*Important*/
    $(' yourModalClassOr#ID ').modal('handleUpdate');

});

100% working.

I know this question is quite old, but I have found a nice solution. Basically, you pass a container layout to this function, and it will apply the font to all supported views, and recursively cicle in child layouts:

public static void setFont(ViewGroup layout)
{
    final int childcount = layout.getChildCount();
    for (int i = 0; i < childcount; i++)
    {
        // Get the view
        View v = layout.getChildAt(i);

        // Apply the font to a possible TextView
        try {
            ((TextView) v).setTypeface(MY_CUSTOM_FONT);
            continue;
        }
        catch (Exception e) { }

        // Apply the font to a possible EditText
        try {
            ((TextView) v).setTypeface(MY_CUSTOM_FONT);
            continue;
        }
        catch (Exception e) { }

        // Recursively cicle into a possible child layout
        try {
            ViewGroup vg = (ViewGroup) v;
            Utility.setFont(vg);
            continue;
        }
        catch (Exception e) { }
    }
}

you should use position:fixed to make z-index values to apply to your div

You can format currency writing your own code but it is just solution for the moment - when your app will grow you can need other currencies.

There is another issue with this:

1. For EN-us - dolar sign is always before currency - $2.00,
2. For selected PL you return sign after amount like 2,00 zl.

I think the best option is use complex solution for internationalization e.g. library vue-i18n( http://kazupon.github.io/vue-i18n/).

I use this plugin and I don't have to worry about such a things. Please look at documentation - it is really simple:

http://kazupon.github.io/vue-i18n/guide/number.html

so you just use:

<div id="app">
  <p>{{ $n(100, 'currency') }}</p>
</div>

and set EN-us to get $100.00:

<div id="app">
  <p>$100.00</p>
</div>

or set PL to get 100,00 zl:

<div id="app">
  <p>100,00 zl</p>
</div>

This plugin also provide different features like translations and date formatting.

Here is a simple one-line solution

((int) ((value + 0.005f) * 100)) / 100f

You would need to have an instance of ClassA within ClassB or have ClassB inherit ClassA

class ClassA {
    public function getName() {
      echo $this->name;
    }
}

class ClassB extends ClassA {
    public function getName() {
      parent::getName();
    }
}

Without inheritance or an instance method, you'd need ClassA to have a static method

class ClassA {
  public static function getName() {
    echo "Rawkode";
  }
}

--- other file ---

echo ClassA::getName();

If you're just looking to call the method from an instance of the class:

class ClassA {
  public function getName() {
    echo "Rawkode";
  }
}

--- other file ---

$a = new ClassA();
echo $a->getName();

Regardless of the solution you choose, require 'ClassA.php is needed.

In ES6, it is also possible to iterate over the values of an object using the for..of loop. This doesn't work right out of the box for JavaScript objects, however, as you must define an @@iterator property on the object. This works as follows:

• The for..of loop asks the "object to be iterated over" (let's call it obj1 for an iterator object. The loop iterates over obj1 by successively calling the next() method on the provided iterator object and using the returned value as the value for each iteration of the loop.
• The iterator object is obtained by invoking the function defined in the @@iterator property, or Symbol.iterator property, of obj1. This is the function you must define yourself, and it should return an iterator object

Here is an example:

const obj1 = {
  a: 5,
  b: "hello",
  [Symbol.iterator]: function() {
    const thisObj = this;
    let index = 0;
    return {
      next() {
        let keys = Object.keys(thisObj);
        return {
          value: thisObj[keys[index++]],
          done: (index > keys.length)
        };
      }
    };
  }
};

Now we can use the for..of loop:

for (val of obj1) {
  console.log(val);
}    // 5 hello

this works for me,

$('#datetimepicker2').datetimepicker({
    startDate: new Date()
  });

Gradle Scripts ->
build.gradle (Module: app) ->
minSdkVersion (Your min sdk version)

You don't need to use display:inline to achieve this:

.inline { 
    border: 1px solid red;
    margin:10px;
    float:left;/*Add float left*/
    margin :10px;
}

You can use float-left.

Using float:left is best way to place multiple div elements in one line. Why? Because inline-block does have some problem when is viewed in IE older versions.

It may be very tempting to do rejectUnauthorized: false or process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = '0'; but don't do it! It exposes you to man in the middle attacks.

The other answers are correct in that the issue lies in the fact that your cert is "signed by an intermediary CA." There is an easy solution to this, one which does not require a third party library like ssl-root-cas or injecting any additional CAs into node.

Most https clients in node support options that allow you to specify a CA per request, which will resolve UNABLE_TO_VERIFY_LEAF_SIGNATURE. Here's a simple example using node's built-int https module.

import https from 'https';

const options = {
  host: '<your host>',
  defaultPort: 443,
  path: '<your path>',
  // assuming the bundle file is co-located with this file
  ca: readFileSync(__dirname + '/<your bundle file>.ca-bundle'),
  headers: {
    'content-type': 'application/json',
  }
};
https.get(options, res => {
  // do whatever you need to do
})

If, however, you can configure the ssl settings in your hosting server, the best solution would be to add the intermediate certificates to your hosting provider. That way the client requester doesn't need to specify a CA, since it's included in the server itself. I personally use namecheap + heroku. The trick for me was to create one .crt file with cat yourcertificate.crt bundle.ca-bundle > server.crt. I then opened up this file and added a newline after the first certificate. You can read more at

https://www.namecheap.com/support/knowledgebase/article.aspx/10050/33/installing-an-ssl-certificate-on-heroku-ssl

I use both Charles Proxy and Fiddler for my HTTP/HTTPS level debugging.

Pros of Charles Proxy:

1. Handles HTTPS better (you get a Charles Certificate which you'd put in 'Trusted Authorities' list)
2. Has more features like Load/Save Session (esp. useful when debugging multiple pages), Mirror a website (useful in caching assets and hence faster debugging), etc.
3. As mentioned by jburgess, handles AMF.
4. Displays JSON, XML and other kind of responses in a tree structure, making it easier to read. Displays images in image responses instead of binary data.

Cons of Charles Proxy:

1. Cost :-)

Specify maven.compiler.source and target versions.

1) Maven version which supports jdk you use. In my case JDK 11 and maven 3.6.0.

2) pom.xml

<properties>
    <maven.compiler.source>11</maven.compiler.source>
    <maven.compiler.target>11</maven.compiler.target>
</properties>

As an alternative, you can fully specify maven compiler plugin. See previous answers. It is shorter in my example :)

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.0</version>
            <configuration>
                <release>11</release>
            </configuration>
        </plugin>
    </plugins>
</build>

3) rebuild the project to avoid compile errors in your IDE.

4) If it still does not work. In Intellij Idea I prefer using terminal instead of using terminal from OS. Then in Idea go to file -> settings -> build tools -> maven. I work with maven I downloaded from apache (by default Idea uses bundled maven). Restart Idea then and run mvn clean install again. Also make sure you have correct Path, MAVEN_HOME, JAVA_HOME environment variables.

I also saw this one-liner, but it does not work.

<maven.compiler.release>11</maven.compiler.release>

I made some quick starter projects, which I re-use in other my projects, feel free to check:

• https://github.com/yan-khonski-it/mvn-pmd-java11

Use the function advance(startIndex, endIndex):

var str = "45+22"
str = str.substringToIndex(advance(str.startIndex, countElements(str) - 1))

I've used mutagen to edit tags in media files before. The nice thing about mutagen is that it can handle other formats, such as mp4, FLAC etc. I've written several scripts with a lot of success using this API.

/^[^;]*/

The [^;] says match anything except a semicolon. The square brackets are a set matching operator, it's essentially, match any character in this set of characters, the ^ at the start makes it an inverse match, so match anything not in this set.

The following code snippet enables/disables a button depending on whether at least one checkbox on the page has been checked.

$('input[type=checkbox]').change(function () {
    $('#test > tbody  tr').each(function () {
        if ($('input[type=checkbox]').is(':checked')) {
            $('#btnexcellSelect').removeAttr('disabled');
        } else {
            $('#btnexcellSelect').attr('disabled', 'disabled');
        }
        if ($(this).is(':checked')){
            console.log( $(this).attr('id'));
         }else{
             console.log($(this).attr('id'));
         }
     });
});

Here is demo in JSFiddle.

Include this code somewhere when you slide to your 'section' called blog.

$("#myLink").click(function() {
    setTimeout(function() {
        window.navigate("the url of the page you want to navigate back to");
    }, 2000);
});

Where myLink is the id of your href.

You just need to declare a as a global in thread2, so that you aren't modifying an a that is local to that function.

def thread2(threadname):
    global a
    while True:
        a += 1
        time.sleep(1)

In thread1, you don't need to do anything special, as long as you don't try to modify the value of a (which would create a local variable that shadows the global one; use global a if you need to)>

def thread1(threadname):
    #global a       # Optional if you treat a as read-only
    while a < 10:
        print a

I don't like the auto-commit that git revert does, so this might be helpful for some.

If you just want the modified files not the auto-commit, you can use --no-commit

% git revert --no-commit <commit hash>

which is the same as the -n

% git revert -n <commit hash>

Here you go: No synchronous tasks.

No synchronous tasks

Synchronous tasks are no longer supported. They often led to subtle mistakes that were hard to debug, like forgetting to return your streams from a task.

When you see the Did you forget to signal async completion? warning, none of the techniques mentioned above were used. You'll need to use the error-first callback or return a stream, promise, event emitter, child process, or observable to resolve the issue.

Using async/await

When not using any of the previous options, you can define your task as an async function, which wraps your task in a promise. This allows you to work with promises synchronously using await and use other synchronous code.

const fs = require('fs');

async function asyncAwaitTask() {
  const { version } = fs.readFileSync('package.json');
  console.log(version);
  await Promise.resolve('some result');
}

exports.default = asyncAwaitTask;

You can use parseInt(string, radix) to convert string value to integer like this code below

var votevalue = parseInt($('button').data('votevalue'));
?

DEMO

If you want your block to return a useful value (e.g. when using #map, #inject, etc.), next and break also accept an argument.

Consider the following:

def contrived_example(numbers)
  numbers.inject(0) do |count, x|
    if x % 3 == 0
      count + 2
    elsif x.odd?
      count + 1
    else 
      count
    end
  end
end

The equivalent using next:

def contrived_example(numbers)
  numbers.inject(0) do |count, x|
    next count if x.even?
    next (count + 2) if x % 3 == 0
    count + 1
  end
end

Of course, you could always extract the logic needed into a method and call that from inside your block:

def contrived_example(numbers)
  numbers.inject(0) { |count, x| count + extracted_logic(x) }
end

def extracted_logic(x)
  return 0 if x.even?
  return 2 if x % 3 == 0
  1
end

The best way is to use your code and then store the image in OG tags in the page you are linking to, then Facebook will pick them up.

<meta property="og:site_name" content="Example Website">
<meta property="og:description" content="Here is a nice description">

open come to play when dealing with multiple modules.

open class is accessible and subclassable outside of the defining module. An open class member is accessible and overridable outside of the defining module.

Here's my improved version of Pointy's solution:

function sortSelectOptions(selector, skip_first) {
    var options = (skip_first) ? $(selector + ' option:not(:first)') : $(selector + ' option');
    var arr = options.map(function(_, o) { return { t: $(o).text(), v: o.value, s: $(o).prop('selected') }; }).get();
    arr.sort(function(o1, o2) {
      var t1 = o1.t.toLowerCase(), t2 = o2.t.toLowerCase();
      return t1 > t2 ? 1 : t1 < t2 ? -1 : 0;
    }); 
    options.each(function(i, o) {
        o.value = arr[i].v;
        $(o).text(arr[i].t);
        if (arr[i].s) {
            $(o).attr('selected', 'selected').prop('selected', true);
        } else {
            $(o).removeAttr('selected');
            $(o).prop('selected', false);
        }
    }); 
}

The function has the skip_first parameter, which is useful when you want to keep the first option on top, e.g. when it's "choose below:".

It also keeps track of the previously selected option.

Example usage:

jQuery(document).ready(function($) {

  sortSelectOptions('#select-id', true);

});

If you want the changes for the last n commits, you can use the following:

git diff HEAD~n

So for the last 5 commits (count including your current commit) from the current commit, it would be:

git diff HEAD~5

Make sure you pip version matches your python version.

to get your python version use:

python -V

then install the correct pip. You might already have intall in that case try to use:

pip-2.5 install ...

pip-2.7 install ...

or for those of you using macports make sure your version match using.

port select --list pip

then change to the same python version you are using.

sudo port select --set pip pip27

Hope this helps. It work on my end.

On any Windows Version follow this path:

C:\Users\{user_name}\AppData\Roaming\Subversion\auth\svn.simple

Then delete the file with hexa decimal code inside this folder and restart your eclipse.

Easy peasy:

var date = DateTime.Parse("14/11/2011"); // may need some Culture help here
Console.Write(date.ToString("yyyy-MM-dd"));

Take a look at DateTime.ToString() method, Custom Date and Time Format Strings and Standard Date and Time Format Strings

string customFormattedDateTimeString = DateTime.Now.ToString("yyyy-MM-dd");

Install Nuget for Oracle.ManagedDataAccess

Make sure you are using header for Oracle:

This Worked for me.

First, one thing to recognize about OS X is that it is built on Unix. This is where the .bash_profile comes in. When you start the Terminal app in OS X you get a bash shell by default. The bash shell comes from Unix and when it loads it runs the .bash_profile script. You can modify this script for your user to change your settings. This file is located at:

~/.bash_profile

Update for Mavericks

OS X Mavericks does not use the environment.plist - at least not for OS X windows applications. You can use the launchd configuration for windowed applications. The .bash_profile is still supported since that is part of the bash shell used in Terminal.

Lion and Mountain Lion Only

OS X windowed applications receive environment variables from the your environment.plist file. This is likely what you mean by the ".plist" file. This file is located at:

~/.MacOSX/environment.plist

If you make a change to your environment.plist file then OS X windows applications, including the Terminal app, will have those environment variables set. Any environment variable you set in your .bash_profile will only affect your bash shells.

Generally I only set variables in my .bash_profile file and don't change the .plist file (or launchd file on Mavericks). Most OS X windowed applications don't need any custom environment. Only when an application actually needs a specific environment variable do I change the environment.plist (or launchd file on Mavericks).

It sounds like what you want is to change the environment.plist file, rather than the .bash_profile.

One last thing, if you look for those files, I think you will not find them. If I recall correctly, they were not on my initial install of Lion.

Edit: Here are some instructions for creating a plist file.

1. Open Xcode
2. Select File -> New -> New File...
3. Under Mac OS X select Resources
4. Choose a plist file
5. Follow the rest of the prompts

To edit the file, you can Control-click to get a menu and select Add Row. You then can add a key value pair. For environment variables, the key is the environment variable name and the value is the actual value for that environment variable.

Once the plist file is created you can open it with Xcode to modify it anytime you wish.

Based on the warning message, the component ReactTooltip renders an HTML that might look like this:

<p>
   <div>...</div>
</p>

According to this document, a <p></p> tag can only contain inline elements. That means putting a <div></div> tag inside it should be improper, since the div tag is a block element. Improper nesting might cause glitches like rendering extra tags, which can affect your javascript and css.

If you want to get rid of this warning, you might want to customize the ReactTooltip component, or wait for the creator to fix this warning.

A reliable way to construct a File instance on a resource retrieved from a jar is it to copy the resource as a stream into a temporary File (the temp file will be deleted when the JVM exits):

public static File getResourceAsFile(String resourcePath) {
    try {
        InputStream in = ClassLoader.getSystemClassLoader().getResourceAsStream(resourcePath);
        if (in == null) {
            return null;
        }

        File tempFile = File.createTempFile(String.valueOf(in.hashCode()), ".tmp");
        tempFile.deleteOnExit();

        try (FileOutputStream out = new FileOutputStream(tempFile)) {
            //copy stream
            byte[] buffer = new byte[1024];
            int bytesRead;
            while ((bytesRead = in.read(buffer)) != -1) {
                out.write(buffer, 0, bytesRead);
            }
        }
        return tempFile;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

You're correct in that the document.getElementById("demo") call gets you the element by the specified ID. But you have to look at the rest of the statement to figure out what exactly the code is doing with that element:

.innerHTML=voteable;

You can see here that it's setting the innerHTML of that element to the value of voteable.

You can use html and be a boss with simple things :

<embed src="music.mp3" width="3000" height="200" controls>

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/

Your makefile should ideally be named makefile, not make. Note that you can call your makefile anything you like, but as you found, you then need the -f option with make to specify the name of the makefile. Using the default name of makefile just makes life easier.

Indexing a list is done using double bracket, i.e. hypo_list[[1]] (e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table does not return a table but a dataframe (see value section in ?read.table). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.

Note: In R, the index for the first entry is a 1 (not 0 like in some other languages).

Dataframes

l <- list(anscombe, iris)   # put dfs in list
l[[1]]             # returns anscombe dataframe

anscombe[1:2, 2]   # access first two rows and second column of dataset
[1] 10  8

l[[1]][1:2, 2]     # the same but selecting the dataframe from the list first
[1] 10  8

Table objects

tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2)  # put tables in a list

tbl1[1:2]              # access first two elements of table 1 

Now with the list

l[[1]]                 # access first table from the list

1  2  3  4  5 
9 11 12  9  9 

l[[1]][1:2]            # access first two elements in first table

1  2 
9 11 

There is a big difference when it comes to child nodes. For example: If you have a parent div and a nested child div. So if you write like this:

<div id="parent" style="display:none;">
    <div id="child" style="display:block;"></div>
</div>

In this case none of the divs will be visible. But if you write like this:

<div id="parent" style="visibility:hidden;">
    <div id="child" style="visibility:visible;"></div>
</div>

Then the child div will be visible whereas the parent div will not be shown.

Simply do this:

<div ng-style="{'background-color': '{{myColorVariable}}', height: '2rem'}"></div>

Local package is a annoying problem in go.

For some projects in our company we decide not use sub packages at all.

• $ glide install
• $ go get
• $ go install

All work.

For some projects we use sub packages, and import local packages with full path:

import "xxxx.gitlab.xx/xxgroup/xxproject/xxsubpackage

But if we fork this project, then the subpackages still refer the original one.

The function linked above is insufficient. It fails to escape ^ or $ (start and end of string), or -, which in a character group is used for ranges.

Use this function:

function escapeRegex(string) {
    return string.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');
}

While it may seem unnecessary at first glance, escaping - (as well as ^) makes the function suitable for escaping characters to be inserted into a character class as well as the body of the regex.

Escaping / makes the function suitable for escaping characters to be used in a JavaScript regex literal for later evaluation.

As there is no downside to escaping either of them, it makes sense to escape to cover wider use cases.

And yes, it is a disappointing failing that this is not part of standard JavaScript.

-m 1 means return the first match in any given file. But it will still continue to search in other files. Also, if there are two or more matched in the same line, all of them will be displayed.

You can use head -1 to solve this problem:

grep -o -a -m 1 -h -r "Pulsanti Operietur" /path/to/dir | head -1

explanation of each grep option:

-o, --only-matching, print only the matched part of the line (instead of the entire line)
-a, --text, process a binary file as if it were text
-m 1, --max-count, stop reading a file after 1 matching line
-h, --no-filename, suppress the prefixing of file names on output
-r, --recursive, read all files under a directory recursively

The ternary operator ? : is to return a value, don't use it when you want to use if for flow control.

if (compareChar(curChar, toChar("0"))) getButtons().get(i).setText("§");

would work good enough.

I do it like this:

<div class="lazyload" style="width: 1000px; height: 600px" data-src="%s">
    <img class="spinner" src="spinner.gif"/>
</div>

and load with

$(window).load(function(){

    $('.lazyload').each(function() {

        var lazy = $(this);
        var src = lazy.attr('data-src');

        $('<img>').attr('src', src).load(function(){
            lazy.find('img.spinner').remove();
            lazy.css('background-image', 'url("'+src+'")');
        });

    });

});

It depends on what the integer is supposed to encode. You could convert the date to a number of milliseconds from some previous time. People often do this affixed to 12:00 am January 1 1970, or 1900, etc., and measure time as an integer number of milliseconds from that point. The datetime module (or others like it) will have functions that do this for you: for example, you can use int(datetime.datetime.utcnow().timestamp()).

If you want to semantically encode the year, month, and day, one way to do it is to multiply those components by order-of-magnitude values large enough to juxtapose them within the integer digits:

2012-06-13 --> 20120613 = 10,000 * (2012) + 100 * (6) + 1*(13)

def to_integer(dt_time):
    return 10000*dt_time.year + 100*dt_time.month + dt_time.day

E.g.

In [1]: import datetime

In [2]: %cpaste
Pasting code; enter '--' alone on the line to stop or use Ctrl-D.
:def to_integer(dt_time):
:    return 10000*dt_time.year + 100*dt_time.month + dt_time.day
:    # Or take the appropriate chars from a string date representation.
:--

In [3]: to_integer(datetime.date(2012, 6, 13))
Out[3]: 20120613

If you also want minutes and seconds, then just include further orders of magnitude as needed to display the digits.

I've encountered this second method very often in legacy systems, especially systems that pull date-based data out of legacy SQL databases.

It is very bad. You end up writing a lot of hacky code for aligning dates, computing month or day offsets as they would appear in the integer format (e.g. resetting the month back to 1 as you pass December, then incrementing the year value), and boiler plate for converting to and from the integer format all over.

Unless such a convention lives in a deep, low-level, and thoroughly tested section of the API you're working on, such that everyone who ever consumes the data really can count on this integer representation and all of its helper functions, then you end up with lots of people re-writing basic date-handling routines all over the place.

It's generally much better to leave the value in a date context, like datetime.date, for as long as you possibly can, so that the operations upon it are expressed in a natural, date-based context, and not some lone developer's personal hack into an integer.

You can do this:

<select  class='form-control' 
        (change)="ChangingValue($event)" [value]='46'>
  <option value='47'>47</option>
  <option value='46'>46</option>
  <option value='45'>45</option>
</select>

// Note: You can set the value of select only from options tag. In the above example, you cannot set the value of select to anything other than 45, 46, 47.

Here, you can ply with this.

One has pretty much control on which information from the traceback to be displayed/logged when catching exceptions.

The code

with open("not_existing_file.txt", 'r') as text:
    pass

would produce the following traceback:

Traceback (most recent call last):
  File "exception_checks.py", line 19, in <module>
    with open("not_existing_file.txt", 'r') as text:
FileNotFoundError: [Errno 2] No such file or directory: 'not_existing_file.txt'

Print/Log the full traceback

As others already mentioned, you can catch the whole traceback by using the traceback module:

import traceback
try:
    with open("not_existing_file.txt", 'r') as text:
        pass
except Exception as exception:
    traceback.print_exc()

This will produce the following output:

Traceback (most recent call last):
  File "exception_checks.py", line 19, in <module>
    with open("not_existing_file.txt", 'r') as text:
FileNotFoundError: [Errno 2] No such file or directory: 'not_existing_file.txt'

You can achieve the same by using logging:

try:
    with open("not_existing_file.txt", 'r') as text:
        pass
except Exception as exception:
    logger.error(exception, exc_info=True)

Output:

__main__: 2020-05-27 12:10:47-ERROR- [Errno 2] No such file or directory: 'not_existing_file.txt'
Traceback (most recent call last):
  File "exception_checks.py", line 27, in <module>
    with open("not_existing_file.txt", 'r') as text:
FileNotFoundError: [Errno 2] No such file or directory: 'not_existing_file.txt'

Print/log error name/message only

You might not be interested in the whole traceback, but only in the most important information, such as Exception name and Exception message, use:

try:
    with open("not_existing_file.txt", 'r') as text:
        pass
except Exception as exception:
    print("Exception: {}".format(type(exception).__name__))
    print("Exception message: {}".format(exception))

Output:

Exception: FileNotFoundError
Exception message: [Errno 2] No such file or directory: 'not_existing_file.txt'

This issue persisted even after the fix from most upvoted answer.

More specific, I pasted in the link without "Ctrl + v", but it still gave fatal: protocol 'https' is not supported.

But if you copy that message in Windows or in Google search bar you will that the actual message is fatal: protocol '##https' is not supported, where '#' stands for this character. As you can see, those 2 characters have not been removed.

I was working on IntelliJ IDEA Community Edition 2019.2.3 and the following fix refers to this tool, but the answer is that those 2 characters are still there and need to be removed from the link.

IntelliJ fix

Go to top bar, select VCS -> Git -> Remotes... and click.

Now it will open something link this

You can see those 2 unrecognised characters. We have to remove them. Either click edit icon and delete those 2 characters or you can delete the link and add a new one.

Make sure you have ".git" folder in your project folder.

And now it should like this. Click "Ok" and now you can push files to your git repository.

You could iterate over the object and assign properties to indexes, like this:

var lookup = [];
var i = 0;

for (var name in obj) {
    if (obj.hasOwnProperty(name)) {
        lookup[i] = obj[name];
        i++;
    }
}

lookup[2] ...

However, as the others have said, the keys are in principle unordered. If you have code which depends on the corder, consider it a hack. Make sure you have unit tests so that you will know when it breaks.

SelectMany() lets you collapse a multidimensional sequence in a way that would otherwise require a second Select() or loop.

I found this page very useful

https://code.google.com/p/spring-finance-manager/source/browse/trunk/src/main/java/net/stsmedia/financemanager/dao/GenericDAOWithJPA.java?r=2

To use the fastboot command you first need to put your device in fastboot mode:

$ adb reboot bootloader

Once the device is in fastboot mode, you can boot it with your own kernel, for example:

$ fastboot boot myboot.img

The above will only boot your kernel once and the old kernel will be used again when you reboot the device. To replace the kernel on the device, you will need to flash it to the device:

$ fastboot flash boot myboot.img

Hope that helps.

Since java 9 Collectors.filtering is enabled:

public static <T, A, R>
    Collector<T, ?, R> filtering(Predicate<? super T> predicate,
                                 Collector<? super T, A, R> downstream)

Thus filtering should be:

collection.stream().collect(Collectors.filtering(predicate, collector))

Example:

List<Integer> oddNumbers = List.of(1, 19, 15, 10, -10).stream()
            .collect(Collectors.filtering(i -> i % 2 == 1, Collectors.toList()));

We can try like this

    recyclerView.getLayoutManager().smoothScrollToPosition(recyclerView,new RecyclerView.State(), recyclerView.getAdapter().getItemCount());

Have you already looked at adding a check constraint on that column which would restrict values? Something like:

CREATE TABLE SomeTable
(
   Id int NOT NULL,
   Frequency varchar(200),
   CONSTRAINT chk_Frequency CHECK (Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly'))
)

If your application needs to handle money values up to a trillion then this should work: 13,2 If you need to comply with GAAP (Generally Accepted Accounting Principles) then use: 13,4

Usually you should sum your money values at 13,4 before rounding of the output to 13,2.

This is my simple solution

var arr = ["you", "are", "the", "love", "of", "my", "life"];
var sorted = arr.sort(function (a, b){
     return b.length - a.length;
});

console.log(sorted[0])

Here's another technique for creating divs with jQuery.

ELEMENT CLONING

Say you have an existing div in your page that you want to clone using jQuery (e.g. to duplicate an input a number of times in a form). You would do so as follows.

$('#clone_button').click(function() {_x000D_
  $('#clone_wrapper div:first')_x000D_
  .clone()_x000D_
  .append('clone')_x000D_
  .appendTo($('#clone_wrapper'));_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="clone_wrapper">_x000D_
  <div>_x000D_
    Div_x000D_
  </div>_x000D_
</div>_x000D_
_x000D_
<button id="clone_button">Clone me!</button>

The paint() method supports painting via a Graphics object.

The repaint() method is used to cause paint() to be invoked by the AWT painting thread.

Give this a try :P

s = '#'.repeat(10)_x000D_
_x000D_
document.body.innerHTML = s

I found a way to do it (dont know if it is the best but it works)

string oldFile = "oldFile.pdf";
string newFile = "newFile.pdf";

// open the reader
PdfReader reader = new PdfReader(oldFile);
Rectangle size = reader.GetPageSizeWithRotation(1);
Document document = new Document(size);

// open the writer
FileStream fs = new FileStream(newFile, FileMode.Create, FileAccess.Write);
PdfWriter writer = PdfWriter.GetInstance(document, fs);
document.Open();

// the pdf content
PdfContentByte cb = writer.DirectContent;

// select the font properties
BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252,BaseFont.NOT_EMBEDDED);
cb.SetColorFill(BaseColor.DARK_GRAY);
cb.SetFontAndSize(bf, 8);

// write the text in the pdf content
cb.BeginText();
string text = "Some random blablablabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(1, text, 520, 640, 0);
cb.EndText();
cb.BeginText();
text = "Other random blabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(2, text, 100, 200, 0);
cb.EndText();

// create the new page and add it to the pdf
PdfImportedPage page = writer.GetImportedPage(reader, 1);
cb.AddTemplate(page, 0, 0);

// close the streams and voilá the file should be changed :)
document.Close();
fs.Close();
writer.Close();
reader.Close();

I hope this can be usefull for someone =) (and post here any errors)

Hey Namratha, If you're asking about changing the text and enabled/disabled state of a UIButton, it can be done pretty easily as follows;

[myButton setTitle:@"Normal State Title" forState:UIControlStateNormal]; // To set the title
[myButton setEnabled:NO]; // To toggle enabled / disabled

If you have created the buttons in the Interface Builder and want to access them in code, you can take advantage of the fact that they are passed in as an argument to the IBAction calls:

- (IBAction) triggerActionWithSender: (id) sender;

This can be bound to the button and you’ll get the button in the sender argument when the action is triggered. If that’s not enough (because you need to access the buttons somewhere else than in the actions), declare an outlet for the button:

@property(retain) IBOutlet UIButton *someButton;

Then it’s possible to bind the button in IB to the controller, the NIB loading code will set the property value when loading the interface.

You are right. This is a badly documented issue. But you can change the font size parameter (by opposition to font scale) directly after building the plot. Check the following example:

import seaborn as sns
tips = sns.load_dataset("tips")

b = sns.boxplot(x=tips["total_bill"])
b.axes.set_title("Title",fontsize=50)
b.set_xlabel("X Label",fontsize=30)
b.set_ylabel("Y Label",fontsize=20)
b.tick_params(labelsize=5)
sns.plt.show()

, which results in this:

To make it consistent in between plots I think you just need to make sure the DPI is the same. By the way it' also a possibility to customize a bit the rc dictionaries since "font.size" parameter exists but I'm not too sure how to do that.

NOTE: And also I don't really understand why they changed the name of the font size variables for axis labels and ticks. Seems a bit un-intuitive.

Provide the source image (img) size as the first rectangle:

ctx.drawImage(img, 0, 0, img.width,    img.height,     // source rectangle
                   0, 0, canvas.width, canvas.height); // destination rectangle

The second rectangle will be the destination size (what source rectangle will be scaled to).

Update 2016/6: For aspect ratio and positioning (ala CSS' "cover" method), check out:
Simulation background-size: cover in canvas

just like this :

global $wpdb;
$table_name='lorem_ipsum';
$results = $wpdb->get_results("SELECT * FROM $table_name ORDER BY ID DESC LIMIT 1");
print_r($results[0]->id);

simply your selecting all the rows then order them DESC by id , and displaying only the first

Write them directly to files.

In Java (ugly):

package xxx;
class XxxUtils {
  public static final Yyy xxx(Xxx xxx) { return xxx.xxx(); }
}

In Kotlin:

@file:JvmName("XxxUtils")
package xxx
fun xxx(xxx: Xxx): Yyy = xxx.xxx()

Those two pieces of codes are equaled after compilation (even the compiled file name, the file:JvmName is used to control the compiled file name, which should be put just before the package name declaration).

For me the filename involved was appended with a querystring, which this function didn't like.

$path = 'path/to/my/file.js?v=2'

Solution was to chop that off first:

$path = preg_replace('/\?v=[\d]+$/', '', $path);
$fileTime = filemtime($path);

I had the same problem, in my case because i forgot this in my NavBar style: overflow: hidden;

How about:

String numbers = text.substring(text.length() - 7);

That assumes that there are 7 characters at the end, of course. It will throw an exception if you pass it "12345". You could address that this way:

String numbers = text.substring(Math.max(0, text.length() - 7));

or

String numbers = text.length() <= 7 ? text : text.substring(text.length() - 7);

Note that this still isn't doing any validation that the resulting string contains numbers - and it will still throw an exception if text is null.

Alternative via Byte Array

If you assign a string to a Byte array you typically get the number equivalents of each character in pairs of the array elements. Use a loop for numeric check via the Like operator and return the joined array as string:

Function Nums(s$)
  Dim by() As Byte, i&, ii&
  by = s: ReDim tmp(UBound(by))                    ' assign string to byte array; prepare temp array
  For i = 0 To UBound(by) - 1 Step 2               ' check num value in byte array (0, 2, 4 ... n-1)
      If Chr(by(i)) Like "#" Then tmp(ii) = Chr(by(i)): ii = ii + 1
  Next i
  Nums = Trim(Join(tmp, vbNullString))             ' return string with numbers only
  End Function

Example call

Sub testByteApproach()
  Dim s$: s = "a12bx99y /\:3,14159"                 ' [1] define original string
  Debug.Print s & " => " & Nums(s)                  ' [2] display original string and result
End Sub

would display the original string and the result string in the immediate window:

  a12bx99y /\:3,14159 => 1299314159

I finally configured RAD to build my Maven-based project, but was getting the following exception when I navigate to a page that uses the Spring taglib:

JSPG0047E: Unable to locate tag library for uri http://www.springframework.org/tags at com.ibm.ws.jsp.translator.visitor.tagfiledep.TagFileDependencyVisitor.visitCustomTagStart(TagFileDependencyVisitor.java:76) ...

The way I had configured my EAR, all the jars were in the EAR, not in the WAR’s WEB-INF/lib. According to the JSP 2.0 spec, I believe tag libs are searched for in all subdirectories of WEB-INF, hence the issue. My solution was to copy the tld files and place under WEB-INF/lib or WEB-INF.. Then it worked.

Get-Content (alias: gc) is your usual option for reading a text file. You can then filter further:

gc log.txt | select -first 10 # head
gc -TotalCount 10 log.txt     # also head
gc log.txt | select -last 10  # tail
gc -Tail 10 log.txt           # also tail (since PSv3), also much faster than above option
gc log.txt | more             # or less if you have it installed
gc log.txt | %{ $_ -replace '\d+', '($0)' }         # sed

This works well enough for small files, larger ones (more than a few MiB) are probably a bit slow.

The PowerShell Community Extensions include some cmdlets for specialised file stuff (e.g. Get-FileTail).

For small functions like this you could just count by hand how many hops it is to the target, from the instruction under the branch instruction. If it branches backwards make that hop number negative. if that number doesn't require all 16 bits, then for every number to the left of the most significant of your hop number, make them 1's, if the hop number is positive make them all 0's Since most branches are close to they're targets, this saves you a lot of extra arithmetic for most cases.

You can make your app as device/profile owner and call setScreenCaptureDisabled(). From the docs, this api does the following:

public void setScreenCaptureDisabled (ComponentName admin, boolean disabled) Added in API level 21

Called by a device/profile owner to set whether the screen capture is disabled. Disabling screen capture also prevents the content from being shown on display devices that do not have a secure video output. See FLAG_SECURE for more details about secure surfaces and secure displays.

The calling device admin must be a device or profile owner. If it is not, a security exception will be thrown. Parameters admin Which DeviceAdminReceiver this request is associated with. disabled Whether screen capture is disabled or not.

Alternatively you can become an MDM(Mobile Device Management) partner app.OEMs provides additional APIs to their MDM partner apps to control the device.For example samsung provides api to control screen recording on the device to their MDM partners.

Currently this is the only way you can enforce screen capture restrictions.

zsh has a builtin command emulate which can emulate different shells by setting the appropriate options, although csh will never be fully emulated.

emulate bash
perform commands
emulate -R zsh

The -R flag restores all the options to their default values for that shell.

See: zsh manual

the best way i found was to set the image you want to view responsively as a background image and sent a css property for the div as cover.

background-image : url('YOUR URL');
background-size : cover

You actually want TestClass.instance_methods, unless you're interested in what TestClass itself can do.

class TestClass
  def method1
  end

  def method2
  end

  def method3
  end
end

TestClass.methods.grep(/method1/) # => []
TestClass.instance_methods.grep(/method1/) # => ["method1"]
TestClass.methods.grep(/new/) # => ["new"]

Or you can call methods (not instance_methods) on the object:

test_object = TestClass.new
test_object.methods.grep(/method1/) # => ["method1"]

If you want that all normal output of your Batch script be silent (like in your example), the easiest way to do that is to run the Batch file with a redirection:

C:\Temp> test.bat >nul

This method does not require to modify a single line in the script and it still show error messages in the screen. To supress all the output, including error messages:

C:\Temp> test.bat >nul 2>&1

If your script have lines that produce output you want to appear in screen, perhaps will be simpler to add redirection to those lineas instead of all the lines you want to keep silent:

@ECHO OFF
SET scriptDirectory=%~dp0
COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat
FOR /F %%f IN ('dir /B "%scriptDirectory%*.noext"') DO (
del "%scriptDirectory%%%f"
)
ECHO
REM Next line DO appear in the screen
ECHO Script completed >con

A quick way is to run a jQuery command in the developer console. On any browser hit F12 and try to access any of the element .

 $("#sideTab2").css("background-color", "yellow");

Actually you can set the default thread culture and UI culture, but only with Framework 4.5+

I put in this static constructor

static MainWindow()
{
  CultureInfo culture = CultureInfo
    .CreateSpecificCulture(CultureInfo.CurrentCulture.Name);
  var dtf = culture.DateTimeFormat;
  dtf.ShortTimePattern = (string)Microsoft.Win32.Registry.GetValue(
    "HKEY_CURRENT_USER\\Control Panel\\International", "sShortTime", "hh:mm tt");
  CultureInfo.DefaultThreadCurrentUICulture = culture;
}

and put a breakpoint in the Convert method of a ValueConverter to see what arrived at the other end. CultureInfo.CurrentUICulture ceased to be en-US and became instead en-AU complete with my little hack to make it respect regional settings for ShortTimePattern.

Hurrah, all is well in the world! Or not. The culture parameter passed to the Convert method is still en-US. Erm, WTF?! But it's a start. At least this way

• you can fix the UI culture once when your app loads
• it's always accessible from CultureInfo.CurrentUICulture
• string.Format("{0}", DateTime.Now) will use your customised regional settings

If you can't use version 4.5 of the framework then give up on setting CurrentUICulture as a static property of CultureInfo and set it as a static property of one of your own classes. This won't fix default behaviour of string.Format or make StringFormat work properly in bindings then walk your app's logical tree to recreate all the bindings in your app and set their converter culture.

There is many way to watch multiple values :

//angular 1.1.4
$scope.$watchCollection(['foo', 'bar'], function(newValues, oldValues){
    // do what you want here
});

or more recent version

//angular 1.3
$scope.$watchGroup(['foo', 'bar'], function(newValues, oldValues, scope) {
  //do what you want here
});

Read official doc for more informations : https://docs.angularjs.org/api/ng/type/$rootScope.Scope

An element with ‘display: block’ (as div is by default) has a width determined by the width of its container. You can't make a block's width dependent on the width of its contents (shrink-to-fit).

(Except for blocks that are ‘float: left/right’ in CSS 2.1, but that's no use for centering.)

You could set the ‘display’ property to ‘inline-block’ to turn a block into a shrink-to-fit object that can be controlled by its parent's text-align property, but browser support is spotty. You can mostly get away with it by using hacks (eg. see -moz-inline-stack) if you want to go that way.

The other way to go is tables. This can be necessary when you have columns whose width really can't be known in advance. I can't really tell what you're trying to do from the example code — there's nothing obvious in there that would need a shrink-to-fit block — but a list of products could possibly be considered tabular.

[PS. never use ‘pt’ for font sizes on the web. ‘px’ is more reliable if you really need fixed size text, otherwise relative units like ‘%’ are better. And “clear: ccc both” — a typo?]

.center{
   text-align:center; 
}

.center > div{ /* N.B. child combinators don't work in IE6 or less */
   display:inline-block;
}

No one mentioned Raw Post Data, but it's good to know, if posted data has no key, but only value, use Raw Post Data:

$postdata = file_get_contents("php://input");

PHP Man:

php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".

Thought I knew I had read about that in the standard; but can't find it. Keeps looking. Old; answering heading; not Q-tex ;P:

The following program would determine that:

#include <stdio.h>
#include <stdint.h>

int is_big_endian(void)
{
    union {
        uint32_t i;
        char c[4];
    } e = { 0x01000000 };

    return e.c[0];
}

int main(void)
{
    printf("System is %s-endian.\n",
        is_big_endian() ? "big" : "little");

    return 0;
}

You also have this approach; from Quake II:

byte    swaptest[2] = {1,0};
if ( *(short *)swaptest == 1) {
    bigendien = false;

And !is_big_endian() is not 100% to be little as it can be mixed/middle.

Believe this can be checked using same approach only change value from 0x01000000 to i.e. 0x01020304 giving:

switch(e.c[0]) {
case 0x01: BIG
case 0x02: MIX
default: LITTLE

But not entirely sure about that one ...

Code bellow allows to play mp3-files and in-memory wave-files too

player.FileName = "123.mp3";
player.Play();

from http://alvas.net/alvas.audio,samples.aspx#sample6 or

Player pl = new Player();
byte[] arr = File.ReadAllBytes(@"in.wav");
pl.Play(arr);

But I wanted to point out that the opinion expressed in the accepted answer is somewhat outdated. According to more recent discussions (django bugs #7634 and #12785), auto_now and auto_now_add are not going anywhere, and even if you go to the original discussion, you'll find strong arguments against the RY (as in DRY) in custom save methods.

A better solution has been offered (custom field types), but didn't gain enough momentum to make it into django. You can write your own in three lines (it's Jacob Kaplan-Moss' suggestion).

from django.db import models
from django.utils import timezone


class AutoDateTimeField(models.DateTimeField):
    def pre_save(self, model_instance, add):
        return timezone.now()

#usage
created_at = models.DateField(default=timezone.now)
updated_at = models.AutoDateTimeField(default=timezone.now)

You should initialize variables to None and then check it:

var1 = None
if var1 is None:
    var1 = 4

Which can be written in one line as:

var1 = 4 if var1 is None else var1

or using shortcut (but checking against None is recommended)

var1 = var1 or 4

alternatively if you will not have anything assigned to variable that variable name doesn't exist and hence using that later will raise NameError, and you can also use that knowledge to do something like this

try:
    var1
except NameError:
    var1 = 4

but I would advise against that.

I usually add separate safe pipe reusable component as following

# Add Safe Pipe

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';

@Pipe({name: 'mySafe'})
export class SafePipe implements PipeTransform {
    constructor(private sanitizer: DomSanitizer) {
    }

    public transform(url) {
        return this.sanitizer.bypassSecurityTrustResourceUrl(url);
    }
}

# then create shared pipe module as following 

import { NgModule } from '@angular/core'; 
import { SafePipe } from './safe.pipe';
@NgModule({
    declarations: [
        SafePipe
    ],
    exports: [
        SafePipe
    ]
})
export class SharedPipesModule {
}

# import shared pipe module in your native module

@NgModule({
    declarations: [],
    imports: [
        SharedPipesModule,
    ],
})
export class SupportModule {
}

<!-------------------
call your url (`trustedUrl` for me) and add `mySafe` as defined in Safe Pipe
---------------->
<div class="container-fluid" *ngIf="trustedUrl">
    <iframe [src]="trustedUrl | mySafe" align="middle" width="100%" height="800" frameborder="0"></iframe>
</div>

I had the same problem when I tried from inside Visual Studio and "git status" in shell showed no problem. But I managed to push the local changes with "git push" via shell.

LinearLayout is a subclass of ViewGroup, which has a method called addView. The addView method should be what you are after.
