If the data is stored in a database it will be faster to send the query to the database instead of getting all data and query it in memory.

A third way to do it will be linq to datasets, but i doubt any of these 3 methods differ much in performance.

I will show visually the problem, using the great example from James answer and adding the alternative solution.

When you do the follow query, without the FETCH:

Select e from Employee e 
join e.phones p 
where p.areaCode = '613'

You will have the follow results from Employee as you expected:

But when you add the FETCH word on JOIN, this is what happens:

The generated SQL is the same for the two queries, but the Hibernate removes on memory the 416 register when you use WHERE on the FETCH join.

So, to bring all phones and apply the WHERE correctly, you need to have two JOINs: one for the WHERE and another for the FETCH. Like:

Select e from Employee e 
join e.phones p 
join fetch e.phones      //no alias, to not commit the mistake
where p.areaCode = '613'

We used mainly Criteria in our application in the beginning but after it was replaced with HQL due to the performance issues.
Mainly we are using very complex queries with several joins which leads to multiple queries in Criteria but is very optimized in HQL.
The case is that we use just several propeties on specific object and not complete objects. With Criteria the problem was also string concatenation.
Let say if you need to display name and surname of the user in HQL it is quite easy (name || ' ' || surname) but in Crteria this is not possible.
To overcome this we used ResultTransormers, where there were methods where such concatenation was implemented for needed result.
Today we mainly use HQL like this:

String hql = "select " +
            "c.uuid as uuid," +
            "c.name as name," +
            "c.objective as objective," +
            "c.startDate as startDate," +
            "c.endDate as endDate," +
            "c.description as description," +
            "s.status as status," +
            "t.type as type " +
            "from " + Campaign.class.getName() + " c " +
            "left join c.type t " +
            "left join c.status s";

Query query =  hibernateTemplate.getSessionFactory().getCurrentSession().getSession(EntityMode.MAP).createQuery(hql);
query.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
return query.list();

so in our case the returned records are maps of needed properties.

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

I am using this one with my codes.

Simply add this to your criteria:

criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);

that code will be like the select distinct * from table of the native sql. Hope this one helps.

This answer is based on user3715338's answer (with a small spelling error corrected) and mixed with Michael's answer for Hibernate 3.6 - based on the accepted answer from Brian Deterling. I then extended it (for PostgreSQL) with a couple more types replacing the questionmarks:

public static String toSql(Criteria criteria)
{
    String sql = "";
    Object[] parameters = null;
    try
    {
        CriteriaImpl criteriaImpl = (CriteriaImpl) criteria;
        SessionImpl sessionImpl = (SessionImpl) criteriaImpl.getSession();
        SessionFactoryImplementor factory = sessionImpl.getSessionFactory();
        String[] implementors = factory.getImplementors(criteriaImpl.getEntityOrClassName());
        OuterJoinLoadable persister = (OuterJoinLoadable) factory.getEntityPersister(implementors[0]);
        LoadQueryInfluencers loadQueryInfluencers = new LoadQueryInfluencers();
        CriteriaLoader loader = new CriteriaLoader(persister, factory,
            criteriaImpl, implementors[0].toString(), loadQueryInfluencers);
        Field f = OuterJoinLoader.class.getDeclaredField("sql");
        f.setAccessible(true);
        sql = (String) f.get(loader);
        Field fp = CriteriaLoader.class.getDeclaredField("translator");
        fp.setAccessible(true);
        CriteriaQueryTranslator translator = (CriteriaQueryTranslator) fp.get(loader);
        parameters = translator.getQueryParameters().getPositionalParameterValues();
    }
    catch (Exception e)
    {
        throw new RuntimeException(e);
    }
    if (sql != null)
    {
        int fromPosition = sql.indexOf(" from ");
        sql = "\nSELECT * " + sql.substring(fromPosition);

        if (parameters != null && parameters.length > 0)
        {
            for (Object val : parameters)
            {
                String value = "%";
                if (val instanceof Boolean)
                {
                    value = ((Boolean) val) ? "1" : "0";
                }
                else if (val instanceof String)
                {
                    value = "'" + val + "'";
                }
                else if (val instanceof Number)
                {
                    value = val.toString();
                }
                else if (val instanceof Class)
                {
                    value = "'" + ((Class) val).getCanonicalName() + "'";
                }
                else if (val instanceof Date)
                {
                    SimpleDateFormat sdf = new SimpleDateFormat(
                        "yyyy-MM-dd HH:mm:ss.SSS");
                    value = "'" + sdf.format((Date) val) + "'";
                }
                else if (val instanceof Enum)
                {
                    value = "" + ((Enum) val).ordinal();
                }
                else
                {
                    value = val.toString();
                }
                sql = sql.replaceFirst("\\?", value);
            }
        }
    }
    return sql.replaceAll("left outer join", "\nleft outer join").replaceAll(
        " and ", "\nand ").replaceAll(" on ", "\non ").replaceAll("<>",
        "!=").replaceAll("<", " < ").replaceAll(">", " > ");
}

Why do you use Restrictions.like(...)?

You should use Restrictions.eq(...).

Note you can also use .le, .lt, .ge, .gt on date objects as comparison operators. LIKE operator is not appropriate for this case since LIKE is useful when you want to match results according to partial content of a column. Please see http://www.sql-tutorial.net/SQL-LIKE.asp for the reference.

For example if you have a name column with some people's full name, you can do where name like 'robert %' so that you will return all entries with name starting with 'robert ' (% can replace any character).

In your case you know the full content of the date you're trying to match so you shouldn't use LIKE but equality. I guess Hibernate doesn't give you any exception in this case, but anyway you will probably have the same problem with the Restrictions.eq(...).

Your date object you got with the code:

SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-YYYY");
String myDate = "17-04-2011";
Date date = formatter.parse(myDate);

This date object is equals to the 17-04-2011 at 0h, 0 minutes, 0 seconds and 0 nanoseconds.

This means that your entries in database must have exactly that date. What i mean is that if your database entry has a date "17-April-2011 19:20:23.707000000", then it won't be retrieved because you just ask for that date: "17-April-2011 00:00:00.0000000000".

If you want to retrieve all entries of your database from a given day, you will have to use the following code:

    SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-YYYY");
    String myDate = "17-04-2011";
    // Create date 17-04-2011 - 00h00
    Date minDate = formatter.parse(myDate);
    // Create date 18-04-2011 - 00h00 
    // -> We take the 1st date and add it 1 day in millisecond thanks to a useful and not so known class
    Date maxDate = new Date(minDate.getTime() + TimeUnit.DAYS.toMillis(1));
    Conjunction and = Restrictions.conjunction();
    // The order date must be >= 17-04-2011 - 00h00
    and.add( Restrictions.ge("orderDate", minDate) );
    // And the order date must be < 18-04-2011 - 00h00
    and.add( Restrictions.lt("orderDate", maxDate) ); 

I'm facing a similar problem. I'm using Query by Example and I want to sort the results by a custom field. In SQL I would do something like:

select pageNo, abs(pageNo - 434) as diff
from relA
where year = 2009
order by diff

It works fine without the order-by-clause. What I got is

Criteria crit = getSession().createCriteria(Entity.class);
crit.add(exampleObject);
ProjectionList pl = Projections.projectionList();
pl.add( Projections.property("id") );
pl.add(Projections.sqlProjection("abs(`pageNo`-"+pageNo+") as diff", new String[] {"diff"}, types ));
crit.setProjection(pl);

But when I add

crit.addOrder(Order.asc("diff"));

I get a org.hibernate.QueryException: could not resolve property: diff exception. Workaround with this does not work either.

PS: as I could not find any elaborate documentation on the use of QBE for Hibernate, all the stuff above is mainly trial-and-error approach

For the new Criteria since version Hibernate 5.2:

CriteriaBuilder criteriaBuilder = getSession().getCriteriaBuilder();
CriteriaQuery<SomeClass> criteriaQuery = criteriaBuilder.createQuery(SomeClass.class);

Root<SomeClass> root = criteriaQuery.from(SomeClass.class);

Path<Object> expressionA = root.get("A");
Path<Object> expressionB = root.get("B");

Predicate predicateAEqualX = criteriaBuilder.equal(expressionA, "X");
Predicate predicateBInXY = expressionB.in("X",Y);
Predicate predicateLeft = criteriaBuilder.and(predicateAEqualX, predicateBInXY);

Predicate predicateAEqualY = criteriaBuilder.equal(expressionA, Y);
Predicate predicateBEqualZ = criteriaBuilder.equal(expressionB, "Z");
Predicate predicateRight = criteriaBuilder.and(predicateAEqualY, predicateBEqualZ);

Predicate predicateResult = criteriaBuilder.or(predicateLeft, predicateRight);

criteriaQuery
        .select(root)
        .where(predicateResult);

List<SomeClass> list = getSession()
        .createQuery(criteriaQuery)
        .getResultList();  

There is another the error happening which related to the order when calling initializing global variables. I've had the sample of code has similar error FailedPreconditionError (see above for traceback): Attempting to use uninitialized value W

def linear(X, n_input, n_output, activation = None):
    W = tf.Variable(tf.random_normal([n_input, n_output], stddev=0.1), name='W')
    b = tf.Variable(tf.constant(0, dtype=tf.float32, shape=[n_output]), name='b')
    if activation != None:
        h = tf.nn.tanh(tf.add(tf.matmul(X, W),b), name='h')
    else:
        h = tf.add(tf.matmul(X, W),b, name='h')
    return h

from tensorflow.python.framework import ops
ops.reset_default_graph()
g = tf.get_default_graph()
print([op.name for op in g.get_operations()])
with tf.Session() as sess:
    # RUN INIT
    sess.run(tf.global_variables_initializer())
    # But W hasn't in the graph yet so not know to initialize 
    # EVAL then error
    print(linear(np.array([[1.0,2.0,3.0]]).astype(np.float32), 3, 3).eval())

You should change to following

from tensorflow.python.framework import ops
ops.reset_default_graph()
g = tf.get_default_graph()
print([op.name for op in g.get_operations()])
with tf.Session() as 
    # NOT RUNNING BUT ASSIGN
    l = linear(np.array([[1.0,2.0,3.0]]).astype(np.float32), 3, 3)
    # RUN INIT
    sess.run(tf.global_variables_initializer())
    print([op.name for op in g.get_operations()])
    # ONLY EVAL AFTER INIT
    print(l.eval(session=sess))

I only put this code in my pom.xml and I executed the command maven install.

Default constructors -- public constructors with out arguments (either declared or implied) -- are inherited by default. You can try the following code for an example of this:

public class CtorTest {
    public static void main(String[] args) {
        final Sub sub = new Sub();
        System.err.println("Finished.");
    }

    private static class Base {
        public Base() {
            System.err.println("In Base ctor");
        }
    }

    private static class Sub extends Base {
        public Sub() {
            System.err.println("In Sub ctor");
        }
    }
}

If you want to explicitly call a constructor from a super class, you need to do something like this:

public class Ctor2Test {
    public static void main(String[] args) {
        final Sub sub = new Sub();
        System.err.println("Finished.");
    }

    private static class Base {
        public Base() {
            System.err.println("In Base ctor");
        }

        public Base(final String toPrint) {
            System.err.println("In Base ctor.  To Print: " + toPrint);
        }
    }

    private static class Sub extends Base {
        public Sub() {
            super("Hello World!");
            System.err.println("In Sub ctor");
        }
    }
}

The only caveat is that the super() call must come as the first line of your constructor, else the compiler will get mad at you.

This the simplest way to assign an async arrow function expression to a named variable:

const foo = async () => {
  // do something
}

_{(Note that this is not strictly equivalent to async function foo() { }. Besides the differences between the function keyword and an arrow expression, the function in this answer is not "hoisted to the top".)}

There is a great Kotlin extension function in Android KTX: View.drawToBitmap(Bitmap.Config)

According to the W3C (and they are the official source on these things), a space character in the query string (and in the query string only) may be encoded as either "%20" or "+". From the section "Query strings" under "Recommendations":

Within the query string, the plus sign is reserved as shorthand notation for a space. Therefore, real plus signs must be encoded. This method was used to make query URIs easier to pass in systems which did not allow spaces.

According to section 3.4 of RFC2396 which is the official specification on URIs in general, the "query" component is URL-dependent:

3.4. Query Component The query component is a string of information to be interpreted by the resource.

   query         = *uric

Within a query component, the characters ";", "/", "?", ":", "@", "&", "=", "+", ",", and "$" are reserved.

It is therefore a bug in the other software if it does not accept URLs with spaces in the query string encoded as "+" characters.

As for the third part of your question, one way (though slightly ugly) to fix the output from URLEncoder.encode() is to then call replaceAll("\\+","%20") on the return value.

So as another answer mentioned Guava has support for this by using:

Streams.stream(iterable);

I want to highlight that the implementation does something slightly different than other answers suggested. If the Iterable is of type Collection they cast it.

public static <T> Stream<T> stream(Iterable<T> iterable) {
  return (iterable instanceof Collection)
    ? ((Collection<T>) iterable).stream()
    : StreamSupport.stream(iterable.spliterator(), false);
}

public static <T> Stream<T> stream(Iterator<T> iterator) {
  return StreamSupport.stream(
    Spliterators.spliteratorUnknownSize(iterator, 0),

When updating tables make sure you do not reference the field your updating via the alias.

I just had the error with the following code

update [page] 
set p.pagestatusid = 1
from [page] p
join seed s on s.seedid = p.seedid
where s.providercode = 'agd'
and p.pagestatusid = 0

I had to remove the alias reference in the set statement so it reads like this

update [page] 
set pagestatusid = 1
from [page] p
join seed s on s.seedid = p.seedid
where s.providercode = 'agd'
and p.pagestatusid = 0

The ability to read an NFC tag has been added to iOS 11 which only support iPhone 7 and 7 plus

As a test drive I made this repo

First: We need to initiate NFCNDEFReaderSession class

var session: NFCNDEFReaderSession? 
session = NFCNDEFReaderSession(delegate: self, queue: nil, invalidateAfterFirstRead: false)

Then we need to start the session by:

session?.begin()

and when done:

session?.invalidate()

The delegate (which self should implement) has basically two functions:

func readerSession(_ session: NFCNDEFReaderSession, didDetectNDEFs messages: [NFCNDEFMessage])
func readerSession(_ session: NFCNDEFReaderSession, didInvalidateWithError error: Error)

here is my reference Apple docs

Use this for functions when you wish to simply alter the original variable and return it again to the same variable name with its new value assigned.

function add(&$var){ // The & is before the argument $var
   $var++;
}
$a = 1;
$b = 10;
add($a);
echo "a is $a,";
add($b);
echo " a is $a, and b is $b"; // Note: $a and $b are NOT referenced

This would be the correct implementation, although I don't see anything you need to dispose in the code you posted. You only need to implement IDisposable when:

1. You have unmanaged resources
2. You're holding on to references of things that are themselves disposable.

Nothing in the code you posted needs to be disposed.

public class User : IDisposable
{
    public int id { get; protected set; }
    public string name { get; protected set; }
    public string pass { get; protected set; }

    public User(int userID)
    {
        id = userID;
    }
    public User(string Username, string Password)
    {
        name = Username;
        pass = Password;
    }

    // Other functions go here...

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    protected virtual void Dispose(bool disposing)
    {
        if (disposing) 
        {
            // free managed resources
        }
        // free native resources if there are any.
    }
}

I wonder if PowerShell 3.0 has a switch that only returns directories; it seems like a logical thing to add.

You are specifying the -i option:

-i, --include

(HTTP) Include the HTTP-header in the output. The HTTP-header includes things like server-name, date of the document, HTTP-version and more...

Simply remove that option from your command line:

response=$(curl -sb -H "Accept: application/json" "http://host:8080/some/resource")

function isTodayOrFuture(date){
  date = stripTime(date);
  return date.diff(stripTime(moment.now())) >= 0;
}

function stripTime(date){
  date = moment(date);
  date.hours(0);
  date.minutes(0);
  date.seconds(0);
  date.milliseconds(0);
  return date;
}

And then just use it line this :

isTodayOrFuture(YOUR_TEST_DATE_HERE)

I would say that it is not in the spirit of Java to run a shell script from Java. Java is meant to be cross platform, and running a shell script would limit its use to just UNIX.

With that said, it's definitely possible to run a shell script from within Java. You'd use exactly the same syntax you listed (I haven't tried it myself, but try executing the shell script directly, and if that doesn't work, execute the shell itself, passing the script in as a command line parameter).

According to the latest Apple Human Interface Guidelines:

In portrait orientation, tab bar icons appear above tab titles. In landscape orientation, the icons and titles appear side-by-side. Depending on the device and orientation, the system displays either a regular or compact tab bar. Your app should include custom tab bar icons for both sizes.

Do you mean include javascript variable values in the query string of the URL?

Yes:

 window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat="+var1+"&lon="+var2+"&setLatLon="+varEtc;

Strictly speaking, there is no difference in meaning; so the choice comes down to convenience.

Here are several factors that could influence your choice:

• House style: Some groups of developers already use one convention or the other.
• Client-side requirements: Will you be using quotes within the strings? (See Ady's answer.)
• Server-side language: VB.NET people might choose to use single quotes for JavaScript so that the scripts can be built server-side (VB.NET uses double-quotes for strings, so the JavaScript strings are easy to distinguished if they use single quotes).
• Library code: If you're using a library that uses a particular style, you might consider using the same style yourself.
• Personal preference: You might think one or other style looks better.

it's not relevant for jQuery ui tooltip property - it's true in bootstrap ui tooltip - my bad!

Exact same thing, just omit the -c option. Apache's docs on it here.

htpasswd /etc/apache2/.htpasswd newuser

Also, htpasswd typically isn't run as root. It's typically owned by either the web server, or the owner of the files being served. If you're using root to edit it instead of logging in as one of those users, that's acceptable (I suppose), but you'll want to be careful to make sure you don't accidentally create a file as root (and thus have root own it and no one else be able to edit it).

One thing to watch out for though, particularly if you are using a framework, is to check if the application is regenerating session ids between requests - anything that depends explicitly on the session id will run into problems, although obviously the rest of the data in the session will unaffected.

If the application is regenerating session ids like this then you can end up with a situation where an ajax request in effect invalidates / replaces the session id in the requesting page.

I use google-api-php-client v2.2.2 I get a new token with fetchAccessTokenWithRefreshToken(); if function call without params, it returns an updated access token and the refreshed token is not lost.

if ($client->getAccessToken() && $client->isAccessTokenExpired()) {
    $new_token=$client->fetchAccessTokenWithRefreshToken();
    $token_data = $client->verifyIdToken();
}    

I had this same problem and solved it by adding an event handler for the play action in addition to the click action. I hide the controls while playing to avoid the pause button issue.

    var v = document.getElementById('videoID');
    v.addEventListener(
       'play', 
          function() { 
             v.play();
          }, 
        false);

    v.onclick = function() {
      if (v.paused) {
        v.play();
        v.controls=null;
      } else {
        v.pause();
        v.controls="controls";
      }
    };

Seeking still acts funny though, but at least the confusion with the play control is gone. Hope this helps.

Anyone have a solution to that?

I used this:

<?php echo get_post_field('post_content', $post->ID); ?>

and this even more concise:

<?= get_post_field('post_content', $post->ID) ?>

Use ", +, y after making a visual selection. You shouldn’t be using the terminal’s copy command anyway, because that copies what the terminal sees instead of the actual content. Here is what this does:

• ",+ tells Vim to use the register named + for the next delete, yank or put. The register named + is a special register, it is the X11 clipboard register. (On other systems, you would use * instead, I think, see :help clipboard and :help x11-selection)
• y is the yank command, which tells Vim to put the selection in the register named previously.

You could map it like this:

:vmap <C-C> "+y

And then highlight something with the mouse and press Control-C to copy it.

This feature only works when Vim has been compiled with the +xterm_clipboard option. Run vim --version to find out if it has.

Main Difference Between PUT and PATCH Requests:

Suppose we have a resource that holds the first name and last name of a person.

If we want to change the first name then we send a put request for Update

{ "first": "Michael", "last": "Angelo" }

Here, although we are only changing the first name, with PUT request we have to send both parameters first and last.
In other words, it is mandatory to send all values again, the full payload.

When we send a PATCH request, however, we only send the data which we want to update. In other words, we only send the first name to update, no need to send the last name.

In theory, there's nothing preventing you from sending a request body in a GET request. The HTTP protocol allows it, but have no defined semantics, so it's up to you to document what exactly is going to happen when a client sends a GET payload. For instance, you have to define if parameters in a JSON body are equivalent to querystring parameters or something else entirely.

However, since there are no clearly defined semantics, you have no guarantee that implementations between your application and the client will respect it. A server or proxy might reject the whole request, or ignore the body, or anything else. The REST way to deal with broken implementations is to circumvent it in a way that's decoupled from your application, so I'd say you have two options that can be considered best practices.

The simple option is to use POST instead of GET as recommended by other answers. Since POST is not standardized by HTTP, you'll have to document how exactly that's supposed to work.

Another option, which I prefer, is to implement your application assuming the GET payload is never tampered with. Then, in case something has a broken implementation, you allow clients to override the HTTP method with the X-HTTP-Method-Override, which is a popular convention for clients to emulate HTTP methods with POST. So, if a client has a broken implementation, it can write the GET request as a POST, sending the X-HTTP-Method-Override: GET method, and you can have a middleware that's decoupled from your application implementation and rewrites the method accordingly. This is the best option if you're a purist.

You can pass semicolon separated values as command argument and then split the string and use it.

<asp:TemplateField ShowHeader="false">
    <ItemTemplate>
       <asp:LinkButton ID="lnkCustomize" Text="Customize"  CommandName="Customize"  CommandArgument='<%#Eval("IdTemplate") + ";" +Eval("EntityId")%>'  runat="server"> 
       </asp:LinkButton>   
    </ItemTemplate>   
</asp:TemplateField>

at server side

protected void gridview_RowCommand(object sender, GridViewCommandEventArgs e)
{
      string[] arg = new string[2];
      arg = e.CommandArgument.ToString().Split(';');
      Session["IdTemplate"] = arg[0];
      Session["IdEntity"] = arg[1];
      Response.Redirect("Samplepage.aspx");
}

Hope it helps!!!!

when using ajax, try $.getJSON() instead of $.get() if you have trouble with the correct display of the results.

In my case i got only the first character of every result when i used $.get(), although i used json_encode() server-side.

This worked for me. I just wanted to close the command window automatically after exiting the game. I just double click on the .bat file on my desktop. No shortcuts.

Used Rn222's answer and aknuds1's answer to use an ISearchContext that returns either a single element, or a list. And a minimum number of elements can be specified:

    /// <returns> The first element found that matches the condition specified</returns>
    public static IWebElement FindElement(this ISearchContext context, By by, uint timeOutInSeconds)
    {
        if (timeOutInSeconds > 0)
        {
            var wait = new DefaultWait<ISearchContext>(context);
            wait.Timeout = TimeSpan.FromSeconds(timeOutInSeconds);
            return wait.Until<IWebElement>(ctx => ctx.FindElement(by));
        }
        return context.FindElement(by);

            return wait.Until<IReadOnlyCollection<IWebElement>>(ctx => ctx.FindElements(by));
        }
        return context.FindElements(by);
    }

        var wait = new DefaultWait<ISearchContext>(context);
        if (timeoutInSeconds > 0)
        {
            wait.Timeout = TimeSpan.FromSeconds(timeoutInSeconds);
        }

        // Wait until the current context found the minimum number of elements. If not found after timeout, an exception is thrown
        wait.Until<bool>(ctx => ctx.FindElements(by).Count >= minNumberOfElements);

        // If the elements were successfuly found, just return the list
        return context.FindElements(by);
    }

}

Example usage:

var driver = new FirefoxDriver();
driver.Navigate().GoToUrl("http://localhost");
var main = driver.FindElement(By.Id("main"));
// It can be now used to wait when using elements to search
var btn = main.FindElement(By.Id("button"), 10);
btn.Click();
// This will wait up to 10 seconds until a button is found
var button = driver.FindElement(By.TagName("button"), 10)
// This will wait up to 10 seconds until a button is found, and return all the buttons found
var buttonList = driver.FindElements(By.TagName("button"), 10)
// This will wait for 10 seconds until we find at least 5 buttons
var buttonsMin = driver.FindElements(By.TagName("button"), 10, 5);
driver.Close();

You must set the setOpaque(true) to true other wise the background will not be painted to the form. I think from reading that if it is not set to true that it will paint some or not any of its pixels to the form. The background is transparent by default which seems odd to me at least but in the way of programming you have to set it to true as shown below.

      JLabel lb = new JLabel("Test");
      lb.setBackground(Color.red);
      lb.setOpaque(true); <--This line of code must be set to true or otherwise the 

From the JavaDocs

setOpaque

public void setOpaque(boolean isOpaque)
  If true the component paints every pixel within its bounds. Otherwise, 
  the component may not paint some or all of its pixels, allowing the underlying 
  pixels to show through.
  The default value of this property is false for JComponent. However, 
  the default value for this property on most standard JComponent subclasses 
   (such as JButton and JTree) is look-and-feel dependent.

Parameters:
isOpaque - true if this component should be opaque
See Also:
isOpaque()

The following should work:

ABC: *\([a-zA-Z]+\) *(.+)

Explanation:

ABC:            # match literal characters 'ABC:'
 *              # zero or more spaces
\([a-zA-Z]+\)   # one or more letters inside of parentheses
 *              # zero or more spaces
(.+)            # capture one or more of any character (except newlines)

To get your desired grouping based on the comments below, you can use the following:

(ABC:) *(\([a-zA-Z]+\).+)

Presuming 17px header height

List css:

height: 100%;
padding-top: 17px;

Header css:

height: 17px;
float: left;
width: 100%;

See here for an example from the OpenJPA docs. CascadeType.ALL means it will do all actions.

Quote:

CascadeType.PERSIST: When persisting an entity, also persist the entities held in its fields. We suggest a liberal application of this cascade rule, because if the EntityManager finds a field that references a new entity during the flush, and the field does not use CascadeType.PERSIST, it is an error.

CascadeType.REMOVE: When deleting an entity, it also deletes the entities held in this field.

CascadeType.REFRESH: When refreshing an entity, also refresh the entities held in this field.

CascadeType.MERGE: When merging entity state, also merge the entities held in this field.

Sebastian

we can do it in more easy way like by adding a function on button and on click we call that function for append.

<div id="Content">
<button id="Add" onclick="append();">Add Text</button>
</div> 
<script type="text/javascript">
function append()
{
$('<p>Text</p>').appendTo('#Content');
}
</script>

What should happen in the case of overflow? If you want it to just get to the bottom of the window, use absolute positioning:

div {
  position: absolute;
  top: 300px;
  bottom: 0px;
  left: 30px;
  right: 30px;
}

This will put the DIV 30px in from each side, 300px from the top of the screen, and flush with the bottom. Add an overflow:auto; to handle cases where the content is larger than the div.

What is it exactly?

An FCM Token, or much commonly known as a registrationToken like in google-cloud-messaging. As described in the GCM FCM docs:

An ID issued by the GCM connection servers to the client app that allows it to receive messages. Note that registration tokens must be kept secret.

How can I get that token?

Update: The token can still be retrieved by calling getToken(), however, as per FCM's latest version, the FirebaseInstanceIdService.onTokenRefresh() has been replaced with FirebaseMessagingService.onNewToken() -- which in my experience functions the same way as onTokenRefresh() did.

Old answer:

As per the FCM docs:

On initial startup of your app, the FCM SDK generates a registration token for the client app instance. If you want to target single devices or create device groups, you'll need to access this token.

You can access the token's value by extending FirebaseInstanceIdService. Make sure you have added the service to your manifest, then call getToken in the context of onTokenRefresh, and log the value as shown:

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    // TODO: Implement this method to send any registration to your app's servers.
    sendRegistrationToServer(refreshedToken);
}

The onTokenRefreshcallback fires whenever a new token is generated, so calling getToken in its context ensures that you are accessing a current, available registration token. FirebaseInstanceID.getToken() returns null if the token has not yet been generated.

After you've obtained the token, you can send it to your app server and store it using your preferred method. See the Instance ID API reference for full detail on the API.

df=pd.read_csv("filename.csv" , parse_dates=["<column name>"])

type(df.<column name>)

example: if you want to convert day which is initially a string to a Timestamp in Pandas

df=pd.read_csv("weather_data2.csv" , parse_dates=["day"])

type(df.day)

The output will be pandas.tslib.Timestamp

The reason that this is happening is because the stack panel measures every child element with positive infinity as the constraint for the axis that it is stacking elements along. The child controls have to return how big they want to be (positive infinity is not a valid return from the MeasureOverride in either axis) so they return the smallest size where everything will fit. They have no way of knowing how much space they really have to fill.

If your view doesn’t need to have a scrolling feature and the answer above doesn't suit your needs, I would suggest implement your own panel. You can probably derive straight from StackPanel and then all you will need to do is change the ArrangeOverride method so that it divides the remaining space up between its child elements (giving them each the same amount of extra space). Elements should render fine if they are given more space than they wanted, but if you give them less you will start to see glitches.

If you want to be able to scroll the whole thing then I am afraid things will be quite a bit more difficult, because the ScrollViewer gives you an infinite amount of space to work with which will put you in the same position as the child elements were originally. In this situation you might want to create a new property on your new panel which lets you specify the viewport size, you should be able to bind this to the ScrollViewer’s size. Ideally you would implement IScrollInfo, but that starts to get complicated if you are going to implement all of it properly.

New way I've just stumbled upon: css calc():

.calculated-width {
    width: -webkit-calc(100% - 100px);
    width:    -moz-calc(100% - 100px);
    width:         calc(100% - 100px);
}?

Source: css width 100% minus 100px

Put a global statement at the top of your function and you should be good:

def onLoadFinished(result):
    global feed
    ...

To demonstrate what I mean, look at this little test:

x = 0
def t():
    x += 1
t()

this blows up with your exact same error where as:

x = 0
def t():
    global x
    x += 1
t()

does not.

The reason for this is that, inside t, Python thinks that x is a local variable. Furthermore, unless you explicitly tell it that x is global, it will try to use a local variable named x in x += 1. But, since there is no x defined in the local scope of t, it throws an error.

We have an app in Google Play and the App Store that will scan barcodes into a web site. The app is called Scan to Web. http://berrywing.com/scantoweb.html

You can even embed a link or button to start the scanner yourself within your web page.

<a href="bwstw://startscanner">Link to start scanner</a>

The developer documentation website for the app covers how to use the app and use JavaScript for processing the barcode scan. http://berrywing.com/scantoweb/#htmlscanbutton

If none of the above answers worked for you, You can try the following solution which worked for me.

Go to Services manager(services.msc) and enable the below services and try again.

You need to put your main code on the OnStart method.

This other SO answer of mine might help.

You will need to put some code to enable debugging within visual-studio while maintaining your application valid as a windows-service. This other SO thread cover the issue of debugging a windows-service.

EDIT:

Please see also the documentation available here for the OnStart method at the MSDN where one can read this:

Do not use the constructor to perform processing that should be in OnStart. Use OnStart to handle all initialization of your service. The constructor is called when the application's executable runs, not when the service runs. The executable runs before OnStart. When you continue, for example, the constructor is not called again because the SCM already holds the object in memory. If OnStop releases resources allocated in the constructor rather than in OnStart, the needed resources would not be created again the second time the service is called.

Execute the workbench.action.reloadWindow command.

There are some ways to do so:

1. Open the command palette (Ctrl + Shift + P) and execute the command:

   >Reload Window    
   

2. Define a keybinding for the command (for example CTRL+F5) in keybindings.json:

   [
     {
       "key": "ctrl+f5",
       "command": "workbench.action.reloadWindow",
       "when": "editorTextFocus"
     }
   ]

None, Python's null?

There's no null in Python; instead there's None. As stated already, the most accurate way to test that something has been given None as a value is to use the is identity operator, which tests that two variables refer to the same object.

>>> foo is None
True
>>> foo = 'bar'
>>> foo is None
False

The basics

There is and can only be one None

None is the sole instance of the class NoneType and any further attempts at instantiating that class will return the same object, which makes None a singleton. Newcomers to Python often see error messages that mention NoneType and wonder what it is. It's my personal opinion that these messages could simply just mention None by name because, as we'll see shortly, None leaves little room to ambiguity. So if you see some TypeError message that mentions that NoneType can't do this or can't do that, just know that it's simply the one None that was being used in a way that it can't.

Also, None is a built-in constant. As soon as you start Python, it's available to use from everywhere, whether in module, class, or function. NoneType by contrast is not, you'd need to get a reference to it first by querying None for its class.

>>> NoneType
NameError: name 'NoneType' is not defined
>>> type(None)
NoneType

You can check None's uniqueness with Python's identity function id(). It returns the unique number assigned to an object, each object has one. If the id of two variables is the same, then they point in fact to the same object.

>>> NoneType = type(None)
>>> id(None)
10748000
>>> my_none = NoneType()
>>> id(my_none)
10748000
>>> another_none = NoneType()
>>> id(another_none)
10748000
>>> def function_that_does_nothing(): pass
>>> return_value = function_that_does_nothing()
>>> id(return_value)
10748000

None cannot be overwritten

In much older versions of Python (before 2.4) it was possible to reassign None, but not any more. Not even as a class attribute or in the confines of a function.

# In Python 2.7
>>> class SomeClass(object):
...     def my_fnc(self):
...             self.None = 'foo'
SyntaxError: cannot assign to None
>>> def my_fnc():
        None = 'foo'
SyntaxError: cannot assign to None

# In Python 3.5
>>> class SomeClass:
...     def my_fnc(self):
...             self.None = 'foo'
SyntaxError: invalid syntax
>>> def my_fnc():
        None = 'foo'
SyntaxError: cannot assign to keyword

It's therefore safe to assume that all None references are the same. There isn't any "custom" None.

To test for None use the is operator

When writing code you might be tempted to test for Noneness like this:

if value==None:
    pass

Or to test for falsehood like this

if not value:
    pass

You need to understand the implications and why it's often a good idea to be explicit.

Case 1: testing if a value is None

Why do

value is None

rather than

value==None

?

The first is equivalent to:

id(value)==id(None)

Whereas the expression value==None is in fact applied like this

value.__eq__(None)

If the value really is None then you'll get what you expected.

>>> nothing = function_that_does_nothing()
>>> nothing.__eq__(None)
True

In most common cases the outcome will be the same, but the __eq__() method opens a door that voids any guarantee of accuracy, since it can be overridden in a class to provide special behavior.

Consider this class.

>>> class Empty(object):
...     def __eq__(self, other):
...         return not other

So you try it on None and it works

>>> empty = Empty()
>>> empty==None
True

But then it also works on the empty string

>>> empty==''
True

And yet

>>> ''==None
False
>>> empty is None
False

Case 2: Using None as a boolean

The following two tests

if value:
    # Do something

if not value:
    # Do something

are in fact evaluated as

if bool(value):
    # Do something

if not bool(value):
    # Do something

None is a "falsey", meaning that if cast to a boolean it will return False and if applied the not operator it will return True. Note however that it's not a property unique to None. In addition to False itself, the property is shared by empty lists, tuples, sets, dicts, strings, as well as 0, and all objects from classes that implement the __bool__() magic method to return False.

>>> bool(None)
False
>>> not None
True

>>> bool([])
False
>>> not []
True

>>> class MyFalsey(object):
...     def __bool__(self):
...         return False
>>> f = MyFalsey()
>>> bool(f)
False
>>> not f
True

So when testing for variables in the following way, be extra aware of what you're including or excluding from the test:

def some_function(value=None):
    if not value:
        value = init_value()

In the above, did you mean to call init_value() when the value is set specifically to None, or did you mean that a value set to 0, or the empty string, or an empty list should also trigger the initialization? Like I said, be mindful. As it's often the case, in Python explicit is better than implicit.

None in practice

None used as a signal value

None has a special status in Python. It's a favorite baseline value because many algorithms treat it as an exceptional value. In such scenarios it can be used as a flag to signal that a condition requires some special handling (such as the setting of a default value).

You can assign None to the keyword arguments of a function and then explicitly test for it.

def my_function(value, param=None):
    if param is None:
        # Do something outrageous!

You can return it as the default when trying to get to an object's attribute and then explicitly test for it before doing something special.

value = getattr(some_obj, 'some_attribute', None)
if value is None:
    # do something spectacular!

By default a dictionary's get() method returns None when trying to access a non-existing key:

>>> some_dict = {}
>>> value = some_dict.get('foo')
>>> value is None
True

If you were to try to access it by using the subscript notation a KeyError would be raised

>>> value = some_dict['foo']
KeyError: 'foo'

Likewise if you attempt to pop a non-existing item

>>> value = some_dict.pop('foo')
KeyError: 'foo'

which you can suppress with a default value that is usually set to None

value = some_dict.pop('foo', None)
if value is None:
    # Booom!

None used as both a flag and valid value

The above described uses of None apply when it is not considered a valid value, but more like a signal to do something special. There are situations however where it sometimes matters to know where None came from because even though it's used as a signal it could also be part of the data.

When you query an object for its attribute with getattr(some_obj, 'attribute_name', None) getting back None doesn't tell you if the attribute you were trying to access was set to None or if it was altogether absent from the object. The same situation when accessing a key from a dictionary, like some_dict.get('some_key'), you don't know if some_dict['some_key'] is missing or if it's just set to None. If you need that information, the usual way to handle this is to directly attempt accessing the attribute or key from within a try/except construct:

try:
    # Equivalent to getattr() without specifying a default
    # value = getattr(some_obj, 'some_attribute')
    value = some_obj.some_attribute
    # Now you handle `None` the data here
    if value is None:
        # Do something here because the attribute was set to None
except AttributeError:
    # We're now handling the exceptional situation from here.
    # We could assign None as a default value if required.
    value = None
    # In addition, since we now know that some_obj doesn't have the
    # attribute 'some_attribute' we could do something about that.
    log_something(some_obj)

Similarly with dict:

try:
    value = some_dict['some_key']
    if value is None:
        # Do something here because 'some_key' is set to None
except KeyError:
    # Set a default
    value = None
    # And do something because 'some_key' was missing
    # from the dict.
    log_something(some_dict)

The above two examples show how to handle object and dictionary cases. What about functions? The same thing, but we use the double asterisks keyword argument to that end:

def my_function(**kwargs):
    try:
        value = kwargs['some_key']
        if value is None:
            # Do something because 'some_key' is explicitly
            # set to None
    except KeyError:
        # We assign the default
        value = None
        # And since it's not coming from the caller.
        log_something('did not receive "some_key"')

None used only as a valid value

If you find that your code is littered with the above try/except pattern simply to differentiate between None flags and None data, then just use another test value. There's a pattern where a value that falls outside the set of valid values is inserted as part of the data in a data structure and is used to control and test special conditions (e.g. boundaries, state, etc.). Such a value is called a sentinel and it can be used the way None is used as a signal. It's trivial to create a sentinel in Python.

undefined = object()

The undefined object above is unique and doesn't do much of anything that might be of interest to a program, it's thus an excellent replacement for None as a flag. Some caveats apply, more about that after the code.

With function

def my_function(value, param1=undefined, param2=undefined):
    if param1 is undefined:
        # We know nothing was passed to it, not even None
        log_something('param1 was missing')
        param1 = None


    if param2 is undefined:
        # We got nothing here either
        log_something('param2 was missing')
        param2 = None

With dict

value = some_dict.get('some_key', undefined)
if value is None:
    log_something("'some_key' was set to None")

if value is undefined:
    # We know that the dict didn't have 'some_key'
    log_something("'some_key' was not set at all")
    value = None

With an object

value = getattr(obj, 'some_attribute', undefined)
if value is None:
    log_something("'obj.some_attribute' was set to None")
if value is undefined:
    # We know that there's no obj.some_attribute
    log_something("no 'some_attribute' set on obj")
    value = None

As I mentioned earlier, custom sentinels come with some caveats. First, they're not keywords like None, so Python doesn't protect them. You can overwrite your undefined above at any time, anywhere in the module it's defined, so be careful how you expose and use them. Next, the instance returned by object() is not a singleton. If you make that call 10 times you get 10 different objects. Finally, usage of a sentinel is highly idiosyncratic. A sentinel is specific to the library it's used in and as such its scope should generally be limited to the library's internals. It shouldn't "leak" out. External code should only become aware of it, if their purpose is to extend or supplement the library's API.

jars use zip compression so you can use any unzip utility.

Example:

$ unzip myJar.jar -d ./directoryToExtractTo

This construction is not allowed in SQL Server. An inline table-valued function can perform as a parameterized view, but is still not allowed to call an SP like this.

Here's some examples of using an SP and an inline TVF interchangeably - you'll see that the TVF is more flexible (it's basically more like a view than a function), so where an inline TVF can be used, they can be more re-eusable:

Although the answers above seems correct, just a simple explanation to give you an idea of how it works.

Suppose that your column is set to be DECIMAL(13,4). This means that the column will have a total size of 13 digits where 4 of these will be used for precision representation.

So, in summary, for that column you would have a max value of: 999999999.9999

this is a character . You can do copy/past without problem

I know that two threads can not enter in Synchronize block at the same time

Two thread cannot enter a synchronized block on the same object twice. This means that two threads can enter the same block on different objects. This confusion can lead to code like this.

private Integer i = 0;

synchronized(i) {
   i++;
}

This will not behave as expected as it could be locking on a different object each time.

if this is true than How this atomic.incrementAndGet() works without Synchronize ?? and is thread safe ??

yes. It doesn't use locking to achieve thread safety.

If you want to know how they work in more detail, you can read the code for them.

And what is difference between internal reading and writing to Volatile Variable / Atomic Variable ??

Atomic class uses volatile fields. There is no difference in the field. The difference is the operations performed. The Atomic classes use CompareAndSwap or CAS operations.

i read in some article that thread has local copy of variables what is that ??

I can only assume that it referring to the fact that each CPU has its own cached view of memory which can be different from every other CPU. To ensure that your CPU has a consistent view of data, you need to use thread safety techniques.

This is only an issue when memory is shared at least one thread updates it.

You can simply put all the files in its specified folder in public like

public/css
public/js
public/images

Then just call the files as in normal html like
<link href="css/file.css" rel="stylesheet" type="text/css">

I am new to .NET/MVC programming, but my understanding is that the Site.css file (under the Content folder in MVC) is a site-level override for Bootstrap CSS, allowing you to override bootstrap native settings in a portable and non-destructive manner (e.g. you can easily save and reapply your site.css changes when updating Bootstrap on your system.)

In Bootstrap 3.0.0, Site.css has the following style setting:

/* Set width on the form input elements since they're 100% wide by default */
input,
select,
textarea {
    max-width: 280px;
}

Other blogs have suggested that this 280px width was added in haste near a release date, in a desire to make the UI look better than it does with 100% width input. Fortunately it was placed in a "visible" location in the site file so you would notice it.

Simply change the width setting, either for all three input types, or pull out textarea and give it its own setting if you want to leave the others alone.

Try this:

if (items.elementAt(1) instanceof Double) {
   sum.add( i, items.elementAt(1));
}

After playing around with a few things, I managed to figure this out myself.

First of all, this will convert a dataURI to a Blob:

function dataURItoBlob(dataURI) {
    // convert base64/URLEncoded data component to raw binary data held in a string
    var byteString;
    if (dataURI.split(',')[0].indexOf('base64') >= 0)
        byteString = atob(dataURI.split(',')[1]);
    else
        byteString = unescape(dataURI.split(',')[1]);

    // separate out the mime component
    var mimeString = dataURI.split(',')[0].split(':')[1].split(';')[0];

    // write the bytes of the string to a typed array
    var ia = new Uint8Array(byteString.length);
    for (var i = 0; i < byteString.length; i++) {
        ia[i] = byteString.charCodeAt(i);
    }

    return new Blob([ia], {type:mimeString});
}

From there, appending the data to a form such that it will be uploaded as a file is easy:

var dataURL = canvas.toDataURL('image/jpeg', 0.5);
var blob = dataURItoBlob(dataURL);
var fd = new FormData(document.forms[0]);
fd.append("canvasImage", blob);

You can use XRegExp, an augmented, extensible, cross-browser implementation of regular expressions, including support for additional syntax, flags, and methods:

• Adds new regex and replacement text syntax, including comprehensive support for named capture.
• Adds two new regex flags: s, to make dot match all characters (aka dotall or singleline mode), and x, for free-spacing and comments (aka extended mode).
• Provides a suite of functions and methods that make complex regex processing a breeze.
• Automagically fixes the most commonly encountered cross-browser inconsistencies in regex behavior and syntax.
• Lets you easily create and use plugins that add new syntax and flags to XRegExp's regular expression language.

Something close to:

@Html.DropDownListFor(m => m.UserRole, 
   new SelectList(Model.Roles, "UserRoleId", "UserRole", Model.Roles.First().UserRoleId), 
   new { /* any html  attributes here */ }) 

You need a SelectList to populate the DropDownListFor. For any HTML attributes you need, you can add:

new { @class = "DropDown", @id = "dropdownUserRole" }

Googling gives many sites... Debugging with the Eclipse platform for one.

My SQL teacher said that if you specify both a DEFAULT value and NOT NULLor NULL, DEFAULT should always be expressed before NOT NULL or NULL.

Like this:

ALTER TABLE tbl ADD COLUMN col VARCHAR(20) DEFAULT "MyDefault" NOT NULL

ALTER TABLE tbl ADD COLUMN col VARCHAR(20) DEFAULT "MyDefault" NULL

@Kwang-Chun Kang Thanks Kang a lot! I found the solution is working and very helpful, it really save my day. For me I am trying to create a React.js component that convert *.xlsx to json object when user upload the excel file to a html input tag. First I need to install XLSX package with:

npm install xlsx --save

Then in my component code, import with:

import XLSX from 'xlsx'

The component UI should look like this:

<input
  accept=".xlsx"
  type="file"
  onChange={this.fileReader}
/>

It calls a function fileReader(), which is exactly same as the solution provided. To learn more about fileReader API, I found this blog to be helpful: https://blog.teamtreehouse.com/reading-files-using-the-html5-filereader-api

I clear my screen using is function that

var clear_body = function (){
    var lista = document.body.childNodes;
    for (var i = lista.length - 1; i >= 0 ;i--){
        document.body.removeChild(lista[i])
    }
}

But boost::filesystem can do that: http://www.boost.org/doc/libs/1_37_0/libs/filesystem/example/simple_ls.cpp

You can simply use../your_script_name.py For example suppose the path to your python script is trading system/trading strategies/ts1.py. To refer to volume.csv located in trading system/data/. You simply need to refer to it as ../data/volume.csv

You can use the folowing code:

def float_range(initVal, itemCount, step):
    for x in xrange(itemCount):
        yield initVal
        initVal += step

[x for x in float_range(1, 3, 0.1)]

Go to http://dev.mysql.com/downloads/connector/j and with in the dropdown select "Platform Independent" then it will show you the options to download tar.gz file or zip file.

Download zip file and extract it, with in that you will find mysql-connector-XXX.jar file

If you are using maven then you can add the dependency from the link http://mvnrepository.com/artifact/mysql/mysql-connector-java

Select the version you want to use and add the dependency in your pom.xml file

Mockito is not a DI framework and even DI frameworks encourage constructor injections over field injections.
So you just declare a constructor to set dependencies of the class under test :

@Mock
private SomeService serviceMock;

private Demo demo;

/* ... */
@BeforeEach
public void beforeEach(){
   demo = new Demo(serviceMock);
}

Using Mockito spy for the general case is a terrible advise. It makes the test class brittle, not straight and error prone : What is really mocked ? What is really tested ?
@InjectMocks and @Spy also hurts the overall design since it encourages bloated classes and mixed responsibilities in the classes.
Please read the spy() javadoc before using that blindly (emphasis is not mine) :

Creates a spy of the real object. The spy calls real methods unless they are stubbed. Real spies should be used carefully and occasionally, for example when dealing with legacy code.

As usual you are going to read the partial mock warning: Object oriented programming tackles complexity by dividing the complexity into separate, specific, SRPy objects. How does partial mock fit into this paradigm? Well, it just doesn't... Partial mock usually means that the complexity has been moved to a different method on the same object. In most cases, this is not the way you want to design your application.

However, there are rare cases when partial mocks come handy: dealing with code you cannot change easily (3rd party interfaces, interim refactoring of legacy code etc.) However, I wouldn't use partial mocks for new, test-driven & well-designed code.

To read characters try

scan("/PathTo/file.csv", "")

If you're reading numeric values, then just use

scan("/PathTo/file.csv")

scan by default will use white space as separator. The type of the second arg defines 'what' to read (defaults to double()).

You should know that it is not possible to directly run a DDL statement like you do for DML from a PL/SQL block because PL/SQL does not support late binding directly it only support compile time binding which is fine for DML. hence to overcome this type of problem oracle has provided a dynamic SQL approach which can be used to execute the DDL statements.The dynamic sql approach is about parsing and binding of sql string at the runtime. Also you should rememder that DDL statements are by default auto commit hence you should be careful about any of the DDL statement using the dynamic SQL approach incase if you have some DML (which needs to be commited explicitly using TCL) before executing the DDL in the stored proc/function.

You can use any of the following dynamic sql approach to execute a DDL statement from a pl/sql block.

1) Execute immediate

2) DBMS_SQL package

3) DBMS_UTILITY.EXEC_DDL_STATEMENT (parse_string IN VARCHAR2);

Hope this answers your question with explanation.

To read a line from a file, you should use the fgets function: It reads a string from the specified file up to either a newline character or EOF.

The use of sscanf in your code would not work at all, as you use filename as your format string for reading from line into a constant string literal %s.

The reason for SEGV is that you write into the non-allocated memory pointed to by line.

   /* 1 */ Foo* foo1 = new Foo ();

Creates an object of type Foo in dynamic memory. foo1 points to it. Normally, you wouldn't use raw pointers in C++, but rather a smart pointer. If Foo was a POD-type, this would perform value-initialization (it doesn't apply here).

   /* 2 */ Foo* foo2 = new Foo;

Identical to before, because Foo is not a POD type.

   /* 3 */ Foo foo3;

Creates a Foo object called foo3 in automatic storage.

   /* 4 */ Foo foo4 = Foo::Foo();

Uses copy-initialization to create a Foo object called foo4 in automatic storage.

   /* 5 */ Bar* bar1 = new Bar ( *new Foo() );

Uses Bar's conversion constructor to create an object of type Bar in dynamic storage. bar1 is a pointer to it.

   /* 6 */ Bar* bar2 = new Bar ( *new Foo );

Same as before.

   /* 7 */ Bar* bar3 = new Bar ( Foo foo5 );

This is just invalid syntax. You can't declare a variable there.

   /* 8 */ Bar* bar3 = new Bar ( Foo::Foo() );

Would work and work by the same principle to 5 and 6 if bar3 wasn't declared on in 7.

5 & 6 contain memory leaks.

Syntax like new Bar ( Foo::Foo() ); is not usual. It's usually new Bar ( (Foo()) ); - extra parenthesis account for most-vexing parse. (corrected)

I got this working with out removing any patches. The above patch was not working too. Finally what I did was on the IIS server install the following patch and reset / restart the IIS server.

in Bootstrap 3 class="affix" works, but in Bootstrap 4 it does not. I solved this problem in Bootstrap 4 with class="sticky-top" (using position: fixed in CSS has its own problems)

code will be something like this:

<div class="row">
    <div class="col-lg-3">
        <div class="sticky-top">
            Fixed content
        </div>
    </div>
    <div class="col-lg-9">
        Normal scrollable content
    </div>
</div>

There are a couple of things that need to be adjusted in your layout:

1. You are nesting col elements within form-group elements. This should be the other way around (the form-group should be within the col-sm-xx element).

2. You should always use a row div for each new "row" in your design. In your case, you would need at least 5 rows (Username, Password and co, Title/First/Last name, email, Language). Otherwise, your problematic .col-sm-12 is still on the same row with the above 3 .col-sm-4 resulting in a total of columns greater than 12, and causing the overlap problem.

Here is a fixed demo.

And an excerpt of what the problematic section HTML should become:

<fieldset>
    <legend>Personal Information</legend>
    <div class='row'>
        <div class='col-sm-4'>    
            <div class='form-group'>
                <label for="user_title">Title</label>
                <input class="form-control" id="user_title" name="user[title]" size="30" type="text" />
            </div>
        </div>
        <div class='col-sm-4'>

                <input class="form-control" id="user_firstname" name="user[firstname]" required="true" size="30" type="text" />

UPDATE MyTable SET MyDate = CONVERT(datetime, '2009/07/16 08:28:01', 120)

For a full discussion of CAST and CONVERT, including the different date formatting options, see the MSDN Library Link below:

https://docs.microsoft.com/en-us/sql/t-sql/functions/cast-and-convert-transact-sql

You can do simple check

if(!a) {
   // do something when `a` is not undefined, null, ''.
}

You need to tag your image correctly first with your registryhost:

docker tag [OPTIONS] IMAGE[:TAG] [REGISTRYHOST/][USERNAME/]NAME[:TAG]

Then docker push using that same tag.

docker push NAME[:TAG]

Example:

docker tag 518a41981a6a myRegistry.com/myImage
docker push myRegistry.com/myImage

A much more robust way would be to use the getline() function of GNU awk to use a variable from a pipe. In form cmd | getline result, cmd is run, then its output is piped to getline. It returns 1 if got output, 0 if EOF, -1 on failure.

First construct the command to run in a variable in the BEGIN clause if the command is not dependant on the contents of the file, e.g. a simple date or an ls.

A simple example of the above would be

awk 'BEGIN {
    cmd = "ls -lrth"
    while ( ( cmd | getline result ) > 0 ) {
        print result
    }
    close(cmd);
}'

When the command to run is part of the columnar content of a file, you generate the cmd string in the main {..} as below. E.g. consider a file whose $2 contains the name of the file and you want it to be replaced with the md5sum hash content of the file. You can do

awk '{ cmd = "md5sum "$2
       while ( ( cmd | getline md5result ) > 0 ) { 
           $2 = md5result
       }
       close(cmd);

Another frequent usage involving external commands in awk is during date processing when your awk does not support time functions out of the box with mktime(), strftime() functions.

Consider a case when you have Unix EPOCH timestamp stored in a column and you want to convert that to a human readable date format. Assuming GNU date is available

awk '{ cmd = "date -d @" $1 " +\"%d-%m-%Y %H:%M:%S\"" 
       while ( ( cmd | getline fmtDate) > 0 ) { 
           $1 = fmtDate
       }
       close(cmd);
}1' 

for an input string as

1572608319 foo bar zoo

the above command produces an output as

01-11-2019 07:38:39 foo bar zoo

The command can be tailored to modify the date fields on any of the columns in a given line. Note that -d is a GNU specific extension, the *BSD variants support -f ( though not exactly similar to -d).

More information about getline can be referred to from this AllAboutGetline article at awk.freeshell.org page.

Yes we can do this using Gson

Download Working code from GitHub

SharedPreferences mPrefs = getPreferences(MODE_PRIVATE);

For save

Editor prefsEditor = mPrefs.edit();
Gson gson = new Gson();
String json = gson.toJson(myObject); // myObject - instance of MyObject
prefsEditor.putString("MyObject", json);
prefsEditor.commit();

For get

Gson gson = new Gson();
String json = mPrefs.getString("MyObject", "");
MyObject obj = gson.fromJson(json, MyObject.class);

Update1

The latest version of GSON can be downloaded from github.com/google/gson.

Update2

If you are using Gradle/Android Studio just put following in build.gradle dependencies section -

implementation 'com.google.code.gson:gson:2.6.2'

String info = "Hello \"world\"!";
info = info.replace("\"", "\\\"");

String info1 = "Hello "world!";
info1 = info1.replace('"', '\"').replace("\"", "\\\"");

For the 2nd field info1, 1st replace double quotes with an escape character.

If you prefer to know which files the workaround is related to here's what I found. Simple change the .classpath file to

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="src" path="gen"/>
    <classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>
    <classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.LIBRARIES"/>
    <classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.DEPENDENCIES"/>
    <classpathentry kind="output" path="bin/classes"/>
</classpath>

Replace the .classpath file in all library projects and in main android project. The .classpath file is in the root folder of the eclipse project. Of cause don't forget to add your own classpath entries, should you have any (so compare with your current version of .classpath).

I believe this is the same result as going through the eclipse menus as componavt-user explained above (Eclipse / Configure Build Path / Order and Export).

I fixed this by setting the Enabled property to false.

Timeit has two big flaws: it doesn't return the return value of the function, and it uses eval, which requires passing in extra setup code for imports. This solves both problems simply and elegantly:

def timed(f):
  start = time.time()
  ret = f()
  elapsed = time.time() - start
  return ret, elapsed

timed(lambda: database.foo.execute('select count(*) from source.apachelog'))
(<sqlalchemy.engine.result.ResultProxy object at 0x7fd6c20fc690>, 4.07547402381897)

You can use do.call:

 do.call("<-",list(parameter_name, parameter_value))

REST means working with the standards of the web, and the standard for "secure" transfer on the web is SSL. Anything else is going to be kind of funky and require extra deployment effort for clients, which will have to have encryption libraries available.

Once you commit to SSL, there's really nothing fancy required for authentication in principle. You can again go with web standards and use HTTP Basic auth (username and secret token sent along with each request) as it's much simpler than an elaborate signing protocol, and still effective in the context of a secure connection. You just need to be sure the password never goes over plain text; so if the password is ever received over a plain text connection, you might even disable the password and mail the developer. You should also ensure the credentials aren't logged anywhere upon receipt, just as you wouldn't log a regular password.

HTTP Digest is a safer approach as it prevents the secret token being passed along; instead, it's a hash the server can verify on the other end. Though it may be overkill for less sensitive applications if you've taken the precautions mentioned above. After all, the user's password is already transmitted in plain-text when they log in (unless you're doing some fancy JavaScript encryption in the browser), and likewise their cookies on each request.

Note that with APIs, it's better for the client to be passing tokens - randomly generated strings - instead of the password the developer logs into the website with. So the developer should be able to log into your site and generate new tokens that can be used for API verification.

The main reason to use a token is that it can be replaced if it's compromised, whereas if the password is compromised, the owner could log into the developer's account and do anything they want with it. A further advantage of tokens is you can issue multiple tokens to the same developers. Perhaps because they have multiple apps or because they want tokens with different access levels.

(Updated to cover implications of making the connection SSL-only.)

OK, after 2 years it's finally time to correct the syntax:

SELECT  t1.value, t2.value
FROM    MyTable t1
JOIN    MyTable t2
ON      t1.id = t2.id
WHERE   t1.id = @id
        AND t1.status = @status1
        AND t2.status = @status2

For me, the refresh in xcode 5 prefs->accounts was doing nothing. At one point it showed me three profiles so I thought I was one refresh away, but after the next refresh it went back to just one profile, so I abandoned this method.

If anyone gets this far and is still struggling, here's what I did:

1. Close xcode 5
2. Open xcode 4.6.2
3. Go to Window->Organizer->Provisioning Profiles
4. Press Refresh arrow on bottom right

When I did this, everything synced up perfectly. It even told me what it was downloading each step of the way like good software does. After the sync completed, I closed xcode 4.6.2, re-opened xcode 5 and went to preferences->accounts and voila, all of my profiles are now available in xocde 5.

On Mac

Netbeans 8.0.2 Tools -> Plugins -> type in search: Dark Look and Feel. Then install plugin.

NOTE: There is no "Option" Or "Appearance" in the "Tools" section in Netbeans 8.0.2.

Considering this issue again: there is a very popular solution that is referenced within this thread that has its origin here:

DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

I have stayed away from this solution because of the use of dirname - it can present cross-platform difficulties, particularly if a script needs to be locked down for security reasons. But as a pure Bash alternative, how about using:

DIR="$( cd "$( echo "${BASH_SOURCE[0]%/*}" )" && pwd )"

Would this be an option?

When you perform operations on Background thread and you want to update UI, you can not call or set anything from background thread. In case of WPF you need Dispatcher.BeginInvoke and in case of WinForms you need Invoke method.

WPF:

// assuming "this" is the window containing your progress bar..
// following code runs in background worker thread...
for(int i=0;i<count;i++)
{
    DoSomething();
    this.Dispatcher.BeginInvoke((Action)delegate(){
         this.progressBar.Value = (int)((100*i)/count);
    });
}

WinForms:

// assuming "this" is the window containing your progress bar..
// following code runs in background worker thread...
for(int i=0;i<count;i++)
{
    DoSomething();
    this.Invoke(delegate(){
         this.progressBar.Value = (int)((100*i)/count);
    });
}

for WinForms delegate may require some casting or you may need little help there, dont remember the exact syntax now.

Here's a nice way for child objects to have access to parent properties and methods using JavaScript's prototype chain, and it's compatible with Internet Explorer. JavaScript searches the prototype chain for methods and we want the child’s prototype chain to looks like this:

Child instance -> Child’s prototype (with Child methods) -> Parent’s prototype (with Parent methods) -> Object prototype -> null

The child methods can also call shadowed parent methods, as shown at the three asterisks *** below.

Here’s how:

//Parent constructor_x000D_
function ParentConstructor(firstName){_x000D_
    //add parent properties:_x000D_
    this.parentProperty = firstName;_x000D_
}_x000D_
_x000D_
//add 2 Parent methods:_x000D_
ParentConstructor.prototype.parentMethod = function(argument){_x000D_
    console.log(_x000D_
            "Parent says: argument=" + argument +_x000D_
            ", parentProperty=" + this.parentProperty +_x000D_
            ", childProperty=" + this.childProperty_x000D_
    );_x000D_
};_x000D_
_x000D_
ParentConstructor.prototype.commonMethod = function(argument){_x000D_
    console.log("Hello from Parent! argument=" + argument);_x000D_
};_x000D_
_x000D_
//Child constructor    _x000D_
function ChildConstructor(firstName, lastName){_x000D_
    //first add parent's properties_x000D_
    ParentConstructor.call(this, firstName);_x000D_
_x000D_
    //now add child's properties:_x000D_
    this.childProperty = lastName;_x000D_
}_x000D_
_x000D_
//insert Parent's methods into Child's prototype chain_x000D_
var rCopyParentProto = Object.create(ParentConstructor.prototype);_x000D_
rCopyParentProto.constructor = ChildConstructor;_x000D_
ChildConstructor.prototype = rCopyParentProto;_x000D_
_x000D_
//add 2 Child methods:_x000D_
ChildConstructor.prototype.childMethod = function(argument){_x000D_
    console.log(_x000D_
            "Child says: argument=" + argument +_x000D_
            ", parentProperty=" + this.parentProperty +_x000D_
            ", childProperty=" + this.childProperty_x000D_
    );_x000D_
};_x000D_
_x000D_
ChildConstructor.prototype.commonMethod = function(argument){_x000D_
    console.log("Hello from Child! argument=" + argument);_x000D_
_x000D_
    // *** call Parent's version of common method_x000D_
    ParentConstructor.prototype.commonMethod(argument);_x000D_
};_x000D_
_x000D_
//create an instance of Child_x000D_
var child_1 = new ChildConstructor('Albert', 'Einstein');_x000D_
_x000D_
//call Child method_x000D_
child_1.childMethod('do child method');_x000D_
_x000D_
//call Parent method_x000D_
child_1.parentMethod('do parent method');_x000D_
_x000D_
//call common method_x000D_
child_1.commonMethod('do common method');

Here's one slight alteration to the answers of a query that creates the table upon execution (i.e. you don't have to create the table first):

SELECT * INTO #Temp
FROM (
select OptionNo, OptionName from Options where OptionActive = 1
) as X

as per 2018, the targetSdkVersion can be set up in your app/build.gradle the following way:

android {
    compileSdkVersion 26
    buildToolsVersion '27.0.3'

    defaultConfig {
       ...
       targetSdkVersion 26
    }
    ...
}

if you choose 26 as SDK target, be sure to follow https://developer.android.com/about/versions/oreo/android-8.0-migration

Go to database, next to title there are 2 options:

Cloud Firestore, Realtime database

Select Realtime database and go to rules

Change rules to true.

The same project (Android Studio 3.3.2, gradle-4.10.1-all.zip, compileSdkVersion 28, buildToolsVersion '28.0.3') works fine on the new fast Windows machine and underline Java 8 stuff by red color on the old Ubuntu 18.04 laptop (however project is compiling without errors on Ubuntu).

The only two things I have changed to force it to stop underlining by red were excluding of incremental true and dexOptions

compileOptions {
//    incremental true
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

//dexOptions {
//    javaMaxHeapSize "4g"
//}

in the app- level build.gradle.

For me the solution was besides using "Ntlm" as credential type:

    XxxSoapClient xxxClient = new XxxSoapClient();
    ApplyCredentials(userName, password, xxxClient.ClientCredentials);

    private static void ApplyCredentials(string userName, string password, ClientCredentials clientCredentials)
    {
        clientCredentials.UserName.UserName = userName;
        clientCredentials.UserName.Password = password;
        clientCredentials.Windows.ClientCredential.UserName = userName;
        clientCredentials.Windows.ClientCredential.Password = password;
        clientCredentials.Windows.AllowNtlm = true;
        clientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
    }  

You can setup a default username via ~/.subversion/servers:

[groups]
yourgroupname = svn.example.com

[yourgroupname]
username = yourusername

Please be aware that older versions of svn do not support it (e.g. 1.3.1 [sic!]).

Use the php's OR (||) logical operator for php isset() with multiple operator e.g

if (isset($_POST['room']) || ($_POST['cottage']) || ($_POST['villa'])) {

}

Great question, and it's odd that the Swing toolkit doesn't include this functionality natively for JTextFields. But, here's a great answer from my Udemy.com course "Learn Java Like a Kid":

txtGuess = new JTextField();
txtGuess.addKeyListener(new KeyAdapter() {
    public void keyTyped(KeyEvent e) { 
        if (txtGuess.getText().length() >= 3 ) // limit textfield to 3 characters
            e.consume(); 
    }  
});

This limits the number of characters in a guessing game text field to 3 characters, by overriding the keyTyped event and checking to see if the textfield already has 3 characters - if so, you're "consuming" the key event (e) so that it doesn't get processed like normal.

You can wrap the label around the input:

 **<label for="a"><input type="checkbox" id="a">a</label>**

This worked for me.

You can use Membership operator:

def list = ['Grace','Rob','Emmy']
assert ('Emmy' in list)  

Membership operator Groovy

This will only work to column Z, but you can drag this horizontally and vertically.

=INDIRECT("'"&$D$2&"'!"&CHAR((COLUMN()+64))&ROW())

Check Is Initial View Controller in the Attributes Inspector.

It's also much more better to not modify the app/config/database.php file itself... otherwise modify .env file and put your DB info there. (.env file is available in Laravel 5, not sure if it was there in previous versions...)

NOTE: Of course you should have already set mysql as your default database connection in the app/config/database.php file.

Download java-json.jar from here, which contains org.json.JSONArray

http://www.java2s.com/Code/JarDownload/java/java-json.jar.zip

nzip and add to your project's library: Project > Build Path > Configure build path> Select Library tab > Add External Libraries > Select the java-json.jar file.

I got similar error (my app crashes) after I renamed something in strings.xml and forgot to modify other files (a preference xml resource file and java code).

IDE (android studio) didn't showed any errors. But, after I repaired my xml files and java code, app ran okay. So, maybe there are some small mistakes in your xml files or constants.

It's not possible to clear user history without plugins. And also it's not an issue at developer's perspective, it's the burden of the user to clear his history.

For information refer to How to clear browsers (IE, Firefox, Opera, Chrome) history using JavaScript or Java except from browser itself?

fopen() will open a resource in the same directory as the file executing the command. In other words, if you're just running the file ~/test.php, your script will create ~/myText.txt.

This can get a little confusing if you're using any URL rewriting (such as in an MVC framework) as it will likely create the new file in whatever the directory contains the root index.php file.

Also, you must have correct permissions set and may want to test before writing to the file. The following would help you debug:

$fp = fopen("myText.txt","wb");
if( $fp == false ){
    //do debugging or logging here
}else{
    fwrite($fp,$content);
    fclose($fp);
}

        if (card1.getRarity() < card2.getRarity()) {
            return 1;

However, if card2.getRarity() is less than card1.getRarity() you might not return -1.

You similarly miss other cases. I would do this, you can change around depending on your intent:

public int compareTo(Object o) {    
    if(this == o){
        return 0;
    }

    CollectionItem item = (CollectionItem) o;

    Card card1 = CardCache.getInstance().getCard(cardId);
    Card card2 = CardCache.getInstance().getCard(item.getCardId());
    int comp=card1.getSet() - card2.getSet();
    if (comp!=0){
        return comp;
    }
    comp=card1.getRarity() - card2.getRarity();
    if (comp!=0){
        return comp;
    }
    comp=card1.getSet() - card2.getSet();
    if (comp!=0){
        return comp;
    }   
    comp=card1.getId() - card2.getId();
    if (comp!=0){
        return comp;
    }   
    comp=card1.getCardType() - card2.getCardType();

    return comp;

    }
}

You need to use something like this:

 OracleCommand oraCommand = new OracleCommand("SELECT fullname FROM sup_sys.user_profile
                       WHERE domain_user_name = :userName", db);

More can be found in this MSDN article: http://msdn.microsoft.com/en-us/library/system.data.oracleclient.oraclecommand.parameters%28v=vs.100%29.aspx

It is advised you use the : character instead of @ for Oracle.

Debugging environment (using Visual Studio)

1a) Stephen Walter's link to set the startup page on MVC using the project properties is only applicable when you are debugging your MVC application.

1b) Right mouse click on the .aspx page in Solution Explorer and select the "Set As Start Page" behaves the same.

Note: in both the above cases, the startup page setting is only recognised by your Visual Studio Development Server. It is not recognised by your deployed server.

Deployed environment

2a) To set the startup page, assuming that you have not change any of the default routings, change the content of /Views/Home/Index.aspx to do a "Server.Transfer" or a "Response.Redirect" to your desired page.

2b) Change your default routing in your global.asax.cs to your desired page.

Are there any other options that the readers are aware of? Which of the above (including your own option) would be your preferred solution (and please share with us why)?

The Scanner should be closed. It is a good practice to close Readers, Streams...and this kind of objects to free up resources and aovid memory leaks; and doing so in a finally block to make sure that they are closed up even if an exception occurs while handling those objects.

You could always treat the list like a stack just popping the elements off the top of the stack from the back end of the list. That way you take advantage of first in last out characteristics of a stack. Of course you are consuming the 1st array. I do like this method in that it's pretty intuitive in that you see one list being consumed from the back end while the other is being built from the front end.

>>> l = [1,2,3,4,5,6]; nl=[]
>>> while l:
        nl.append(l.pop())  
>>> print nl
[6, 5, 4, 3, 2, 1]

Here's a way to do it:

// The method to call
void Foo()
{
}


Action action = Foo;
action.BeginInvoke(ar => action.EndInvoke(ar), null);

Of course you need to replace Action by another type of delegate if the method has a different signature

HTTPScoop is awesome for inspecting the web traffic on your Mac. It's been incredibly helpful for me. I didn't think twice about the $15 price tag. There is a 14 day trial.

Resolved it in 2 minutes downtime :)
Just move your folder, add symlink, then tune permissions.

sudo service mongod stop
sudo mv mongodb /new/disk/mongodb/
sudo ln -s /new/disk/mongodb/ /var/lib/mongodb
sudo chown mongodb:mongodb /new/disk/mongodb/
sudo service mongod start

# test if mongodb user can access new location:
sudo -u mongodb -s cd /new/disk/mongodb/
# resolve other permissions issues if necessary
sudo usermod -a -G <newdisk_grp> mongodb

this code will work with OI File Manager :

        File root = new File(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
        Uri uri = Uri.fromFile(root);

        Intent intent = new Intent();
        intent.setAction(android.content.Intent.ACTION_VIEW);
        intent.setData(uri);
        startActivityForResult(intent, 1);

Please do not use NSDate, CFAbsoluteTimeGetCurrent, or gettimeofday to measure elapsed time. These all depend on the system clock, which can change at any time due to many different reasons, such as network time sync (NTP) updating the clock (happens often to adjust for drift), DST adjustments, leap seconds, and so on.

This means that if you're measuring your download or upload speed, you will get sudden spikes or drops in your numbers that don't correlate with what actually happened; your performance tests will have weird incorrect outliers; and your manual timers will trigger after incorrect durations. Time might even go backwards, and you end up with negative deltas, and you can end up with infinite recursion or dead code (yeah, I've done both of these).

Use mach_absolute_time. It measures real seconds since the kernel was booted. It is monotonically increasing (will never go backwards), and is unaffected by date and time settings. Since it's a pain to work with, here's a simple wrapper that gives you NSTimeIntervals:

// LBClock.h
@interface LBClock : NSObject
+ (instancetype)sharedClock;
// since device boot or something. Monotonically increasing, unaffected by date and time settings
- (NSTimeInterval)absoluteTime;

- (NSTimeInterval)machAbsoluteToTimeInterval:(uint64_t)machAbsolute;
@end

// LBClock.m
#include <mach/mach.h>
#include <mach/mach_time.h>

@implementation LBClock
{
    mach_timebase_info_data_t _clock_timebase;
}

+ (instancetype)sharedClock
{
    static LBClock *g;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        g = [LBClock new];
    });
    return g;
}

- (id)init
{
    if(!(self = [super init]))
        return nil;
    mach_timebase_info(&_clock_timebase);
    return self;
}

- (NSTimeInterval)machAbsoluteToTimeInterval:(uint64_t)machAbsolute
{
    uint64_t nanos = (machAbsolute * _clock_timebase.numer) / _clock_timebase.denom;

    return nanos/1.0e9;
}

- (NSTimeInterval)absoluteTime
{
    uint64_t machtime = mach_absolute_time();
    return [self machAbsoluteToTimeInterval:machtime];
}
@end

Hope, It helps.

Really depends on your requirement, although lately I have seen a trend for classes with at least one bare constructor defined.

The upside of posting your parameters in via constructor is that you know those values can be relied on after instantiation. The downside is that you'll need to put more work in with any library that expects to be able to create objects with a bare constructor.

My personal preference is to go with a bare constructor and set any properties as part of the declaration.

Person p=new Person()
{
   Name = "Han Solo",
   Age = 39
};

This gets around the "class lacks bare constructor" problem, plus reduces maintenance ( I can set more things without changing the constructor ).

When you run a program as a background process (by adding an & after it), e.g.:

python -m SimpleHTTPServer 8888 &

If the terminal window is still open you can do:

jobs

To get a list of all background jobs within the running shell's process.

It could look like this:

$ jobs
[1]+  Running                 python -m SimpleHTTPServer 8888 &

To kill a job, you can either do kill %1 to kill job "[1]", or do fg %1 to put the job in the foreground (fg) and then use ctrl-c to kill it. (Simply entering fg will put the last backgrounded process in the foreground).

With respect to SimpleHTTPServer it seems kill %1 is better than fg + ctrl-c. At least it doesn't protest with the kill command.

The above has been tested in Mac OS, but as far as I can remember it works just the same in Linux.

Update: For this to work, the web server must be started directly from the command line (verbatim the first code snippet). Using a script to start it will put the process out of reach of jobs.

I created a function similar to what Nick did, but my method would not require setting the dialogClass and you will be able to get the buttons of a specific dialog via the id (if more than one exists in your application)

function getDialogButton( dialog_id, button_name) {
    var target = '#'+dialog_id;
    var buttons = $(target).parent().find('button');
    for ( var i=0; i<buttons.length; ++i ) {
        var jButton = $( buttons[i] );
        if ( jButton.text() == button_name ) {
              return jButton;
        }
    }
    return null;
} 

So if you created the dialog like so:

$(function() {
    $("#myDialogBox").dialog({

      bgiframe: true, height: 'auto', width: 700, modal: true,
      buttons: {
        'Add to request list': function() {
                                     $(this).dialog('close');
                                     $('form').submit();
                               },
        'Cancel': function() {
                       $(this).dialog('close');
                  }
      }
});

You can get the buttons by doing the following:

var addToRequestListBtn = getDialogButton('myDialogBox','Add to request list');
var cancelBtn           = getDialogButton('myDialogBox','Cancel');

To disable:

addToRequestListBtn.attr('disabled', true).addClass( 'ui-state-disabled');
          cancelBtn.attr('disabled', true).addClass( 'ui-state-disabled');

To enable:

addToRequestListBtn.attr('disabled', false).removeClass( 'ui-state-disabled');
          cancelBtn.attr('disabled', false).removeClass( 'ui-state-disabled');

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

It's not officially supported yet.

Edit: It's now supported in modern versions of Android Studio, at least on some platforms.

Old workarounds

If you're using an old version of Android Studio which doesn't support the Google Play Store, and you refuse to upgrade, here are two possible workarounds:

1. Ask your favorite app's maintainers to upload a copy of their app into the Amazon Appstore. Next, install the Appstore onto your Android device. Finally, use the Appstore to install your favorite app.

2. Or: Do a Web search to find a .apk file for the software you want. For example, if you want to install SleepBot in your Android emulator, you can do a Google Web search for [ SleepBot apk ]. Then use adb install to install the .apk file.

Here is a method to get lines between two line numbers in a file:

import sys

def file_line(name,start=1,end=sys.maxint):
    lc=0
    with open(s) as f:
        for line in f:
            lc+=1
            if lc>=start and lc<=end:
                yield line


s='/usr/share/dict/words'
l1=list(file_line(s,235880))
l2=list(file_line(s,1,10))
print l1
print l2

Output:

['Zyrian\n', 'Zyryan\n', 'zythem\n', 'Zythia\n', 'zythum\n', 'Zyzomys\n', 'Zyzzogeton\n']
['A\n', 'a\n', 'aa\n', 'aal\n', 'aalii\n', 'aam\n', 'Aani\n', 'aardvark\n', 'aardwolf\n', 'Aaron\n']

Just call it with one parameter to get from line n -> EOF

Probably the cleanest solution:

abstract class NavigationChildFragment : Fragment() {

    abstract fun onCreateChildView(inflater: LayoutInflater,
                                   container: ViewGroup?,
                                   savedInstanceState: Bundle?): View?

    override fun onCreateView(inflater: LayoutInflater,
                              container: ViewGroup?,
                              savedInstanceState: Bundle?): View? {
        val activity = activity as? MainActivity
        activity?.supportActionBar?.setDisplayHomeAsUpEnabled(true)
        setHasOptionsMenu(true)
        return onCreateChildView(inflater, container, savedInstanceState)
    }

    override fun onDestroyView() {
        val activity = activity as? MainActivity
        activity?.supportActionBar?.setDisplayHomeAsUpEnabled(false)
        setHasOptionsMenu(false)
        super.onDestroyView()
    }

    override fun onOptionsItemSelected(item: MenuItem): Boolean {
        val activity = activity as? MainActivity
        return when (item.itemId) {
            android.R.id.home -> {
                activity?.onBackPressed()
                true
            }
            else              -> super.onOptionsItemSelected(item)
        }
    }
}

Just use this class as parent for all Fragments that should support navigation.

1. IEnumerable<DataRow> rows = dataTable.AsEnumerable(); (System.Data.DataSetExtensions.dll)
2. IEnumerable<DataRow> rows = dataTable.Rows.OfType<DataRow>(); (System.Core.dll)

Both the org.hibernate.Session API and javax.persistence.EntityManager API represent a context for dealing with persistent data.

This concept is called a persistence context. Persistent data has a state in relation to both a persistence context and the underlying database.

If you have queries to a DBMS for which the locality is quite restricted (say, a user only fires selects with a 'where username = $my_username') it makes sense to put all the usernames starting with A-M on one server and all from N-Z on the other. By this you get near linear scaling for some queries.

Long story short: Sharding is basically the process of distributing tables onto different servers in order to balance the load onto both equally.

Of course, it's so much more complicated in reality. :)

Partition - Split an array by a pivot that smaller elements move to the left and greater elemets move to the right or vice versa. A pivot can be an random element from an array. To make this algorith we need to know what is begin and end index of an array and where is a pivot. Then set two auxiliary pointers L, R.

So we have an array user[...,begin,...,end,...]

The start position of L and R pointers
[...,begin,next,...,end,...]
     R       L

while L < end
  1. If a user[pivot] > user[L] then move R by one and swap user[R] with user[L]
  2. move L by one

After while swap user[R] with user[pivot]

Quick sort - Use the partition algorithm until every next part of the split by a pivot will have begin index greater or equals than end index.

def qsort(user, begin, end):

    if begin >= end:
        return

    # partition
    # pivot = begin
    L = begin+1
    R = begin
    while L < end:
        if user[begin] > user[L]:
            R+=1
            user[R], user[L] = user[L], user[R]
        L+= 1
    user[R], user[begin] = user[begin], user[R]

    qsort(user, 0, R)
    qsort(user, R+1, end)

You should use setStroke to set a stroke of the Graphics2D object.

The example at http://www.java2s.com gives you some code examples.

The following code produces the image below:

import java.awt.*;
import java.awt.geom.Line2D;
import javax.swing.*;

public class FrameTest {
    public static void main(String[] args) {
        JFrame jf = new JFrame("Demo");
        Container cp = jf.getContentPane();
        cp.add(new JComponent() {
            public void paintComponent(Graphics g) {
                Graphics2D g2 = (Graphics2D) g;
                g2.setStroke(new BasicStroke(10));
                g2.draw(new Line2D.Float(30, 20, 80, 90));
            }
        });
        jf.setSize(300, 200);
        jf.setVisible(true);
    }
}

(Note that the setStroke method is not available in the Graphics object. You have to cast it to a Graphics2D object.)

This problem can happen if different versions of g++ and gcc are installed.

   g++ --version
   gcc --version

If these don't give the result, you probably have multiple versions of gcc installed. You can check by using:

    dpkg -l | grep gcc | awk '{print $2}'

Usually, /usr/bin/gcc will be sym-linked to /etc/alternatives/gcc which is again sym-linked to say /usr/bin/gcc-4.6 or /usr/bin/gcc-4.8 (In case you have gcc-4.6, gcc-4.8 installed.)

By changing this link you can make gcc and g++ run in the same version and this may resolve your issue!

The below regex would match white spaces but not of a new line character.

(?:(?!\n)\s)

DEMO

If you want to add carriage return also then add \r with the | operator inside the negative lookahead.

(?:(?![\n\r])\s)

DEMO

Add + after the non-capturing group to match one or more white spaces.

(?:(?![\n\r])\s)+

DEMO

I don't know why you people failed to mention the POSIX character class [[:blank:]] which matches any horizontal whitespaces (spaces and tabs). This POSIX chracter class would work on BRE(Basic REgular Expressions), ERE(Extended Regular Expression), PCRE(Perl Compatible Regular Expression).

DEMO

Use a TreeMap, although having a map "look like that" is a bit nebulous--you could also just sort the keys based on your criteria and iterate over the map, retrieving each object.

For people familiar with GIT, master in GIT is equivalent to trunk in SVN.

Branch and tag has same terminology in both GIT and SVN.

First of all, two things that we need to understand,

Client

• It makes request to a specific server

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

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

Server

• It handles the request of the client and makes replica of its own which is private to client only who send request and this raplica of server runs on different thread.

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

• Server sends response with IBinder Object. So, IBinder object is our handler which accesses all the methods of Service by using (.) operator.

.

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

    public void onServiceDisconnected(ComponentName className) {
        Log.d("ServiceConnection","disconnected");
        myService = null;
    }
}

Now how to call method which lies in service

myservice.serviceMethod();

Here myService is object and serviceMethod is method in service. and by this way communication is established between client and server.

to make it easier for you here is the code that i use :

w, h = image.shape
top=10
right=50
down=15
left=80
croped_image = image[top:((w-down)+top), right:((h-left)+right)]
plt.imshow(croped_image, cmap="gray")
plt.show()

// Register user's name and ID

if ((!isset($_SESSION['name'])) && (!isset($_SESSION['user_id'])))  {
    $row = mysql_fetch_assoc($login_result);
    $_SESSION['name'] = $row['name'];
    $_SESSION['user_id'] = $row['user_id'];
}

header("Location: http://localhost:8080/meet2eat/index.php");

change to

// Register user's name and ID

if ((!isset($_SESSION['name'])) && (!isset($_SESSION['user_id'])))  {
    $row = mysql_fetch_assoc($login_result);
    $_SESSION['name'] = $row['name'];
    $_SESSION['user_id'] = $row['user_id'];
header("Location: http://localhost:8080/meet2eat/index.php");
}

No need to use BufferedImage, as you already have the image file in a byte array

    byte dearr[] = Base64.decodeBase64(crntImage);
    FileOutputStream fos = new FileOutputStream(new File("c:/decode/abc.bmp")); 
    fos.write(dearr); 
    fos.close();

How about rev(x)[1:5]?

x<-1:10
system.time(replicate(10e6,tail(x,5)))
 user  system elapsed 
 138.85    0.26  139.28 

system.time(replicate(10e6,rev(x)[1:5]))
 user  system elapsed 
 61.97    0.25   62.23

my way...

const myForm = document.forms['form-name']

myForm.onsubmit=e=>
  {
  e.preventDefault()  // for testing...

  let data = Array.from(new FormData(myForm))
                  .reduce((r,[k,v])=>{r[k]=v;return r},{})

  /*_______________________________________ same code: for beginners 
  let data = {}
  Array.from(new FormData(myForm), (entry) => { data[ entry[0] ] = entry[1]} )
  ________________________________________________________________*/
 
  console.log(data)
  
  //...
  }

In my case, display: block was breaking the design as intended.

The max-width property just saved me.

and for styling, you can use text-overflow: ellipsis as well.

my code was

max-width: 255px
overflow:hidden

In java 8, it's convenient to use the new date lib and getEpochSecond method to get the timestamp (it's in second)

Instant.now().getEpochSecond();

There is also quick solution using the imputeTS package:

library(imputeTS)
na_mean(yourDataFrame)

For others like me:

There was once an example in the SSL source in the directory demos/ssl/ with example code in C++. Now it's available only via the history: https://github.com/openssl/openssl/tree/691064c47fd6a7d11189df00a0d1b94d8051cbe0/demos/ssl

You probably will have to find a working version, I originally posted this answer at Nov 6 2015. And I had to edit the source -- not much.

Certificates: .pem in demos/certs/apps/: https://github.com/openssl/openssl/tree/master/demos/certs/apps

For the most part you treat it as if you are validating any other kind of control but use the InitialValue property of the required field validator.

<asp:RequiredFieldValidator ID="rfv1" runat="server" ControlToValidate="your-dropdownlist" InitialValue="Please select" ErrorMessage="Please select something" />

Basically what it's saying is that validation will succeed if any other value than the 1 set in InitialValue is selected in the dropdownlist.

If databinding you will need to insert the "Please select" value afterwards as follows

this.ddl1.Items.Insert(0, "Please select");

You can use style display:none with tr to hide and it will work with all browsers.

Well, longs can't hold anything but integers.

One option is to use a float: float('234.89')

The other option is to truncate or round. Converting from a float to a long will truncate for you: long(float('234.89'))

>>> long(float('1.1'))
1L
>>> long(float('1.9'))
1L
>>> long(round(float('1.1')))
1L
>>> long(round(float('1.9')))
2L

I'm using something very similar to Clement's answer:

private int GetSignificantDecimalPlaces(decimal number, bool trimTrailingZeros = true)
{
  string stemp = Convert.ToString(number);

  if (trimTrailingZeros)
    stemp = stemp.TrimEnd('0');

  return stemp.Length - 1 - stemp.IndexOf(
         Application.CurrentCulture.NumberFormat.NumberDecimalSeparator);
}

Remember to use System.Windows.Forms to get access to Application.CurrentCulture

Just add these line in info.plist file:

<key>UIUserInterfaceStyle</key>
<string>light</string>

This will force app to run in light mode only.

Sometimes this can refer to another scope and refer to something else, for example suppose you want to call a constructor method inside a DOM event, in this case this will refer to the DOM element not the created object.

HTML

<button id="button">Alert Name</button>

JS

var Person = function(name) {
  this.name = name;
  var that = this;
  this.sayHi = function() {
    alert(that.name);
  };
};

var ahmad = new Person('Ahmad');
var element = document.getElementById('button');
element.addEventListener('click', ahmad.sayHi); // => Ahmad

Demo

The solution above will assing this to that then we can and access the name property inside the sayHi method from that, so this can be called without issues inside the DOM call.

Another solution is to assign an empty that object and add properties and methods to it and then return it. But with this solution you lost the prototype of the constructor.

var Person = function(name) {
  var that = {};
  that.name = name;
  that.sayHi = function() {
    alert(that.name);
  };
  return that;
};

For you LINQers out there that never use a regular dictionary constructor

myCollection.ToDictionary(x => x.PartNumber, x => x.PartDescription, StringComparer.OrdinalIgnoreCase)

Remove element should clear out such errors. The reason behind this is the inherited settings. Your application will inherit some settings from its parent's config file and machine's (server) config files.
You can either remove such duplicates with the remove tag before adding them or make these tags non-inheritable in the upper level config files.

Use this stylesheet:

Use Polly

https://github.com/App-vNext/Polly-Samples

Here is a retry-generic I use with Polly

public T Retry<T>(Func<T> action, int retryCount = 0)
{
    PolicyResult<T> policyResult = Policy
     .Handle<Exception>()
     .Retry(retryCount)
     .ExecuteAndCapture<T>(action);

    if (policyResult.Outcome == OutcomeType.Failure)
    {
        throw policyResult.FinalException;
    }

    return policyResult.Result;
}

Use it like this

var result = Retry(() => MyFunction()), 3);

another way would be to use dplyr package:

x = c(1,1,2,3,4,4,4)
dplyr::distinct(as.data.frame(x))

The fastest solution for big files is always tail|head, provided that the two distances:

• from the start of the file to the starting line. Lets call it S
• the distance from the last line to the end of the file. Be it E

are known. Then, we could use this:

mycount="$E"; (( E > S )) && mycount="+$S"
howmany="$(( endline - startline + 1 ))"
tail -n "$mycount"| head -n "$howmany"

howmany is just the count of lines required.

At my last job we ran statistics once a week. If I remember correctly, we scheduled them on a Thursday night, and on Friday the DBAs were very careful to monitor the longest running queries for anything unexpected. (Friday was picked because it was often just after a code release, and tended to be a fairly low traffic day.) When they saw a bad query they would find a better query plan and save that one so it wouldn't change again unexpectedly. (Oracle has tools to do this for you automatically, you tell it the query to optimize and it does.)

Many organizations avoid running statistics out of fear of bad query plans popping up unexpectedly. But this usually means that their query plans get worse and worse over time. And when they do run statistics then they encounter a number of problems. The resulting scramble to fix those issues confirms their fears about the dangers of running statistics. But if they ran statistics regularly, used the monitoring tools as they are supposed to, and fixed issues as they came up then they would have fewer headaches, and they wouldn't encounter them all at once.

Although maven exec does the trick here, I found it pretty poor for a real test. While waiting for maven shell, and hoping this could help others, I finally came out to this repo mvnexec

Clone it, and symlink the script somewhere in your path. I use ~/bin/mvnexec, as I have ~/bin in my path. I think mvnexec is a good name for the script, but is up to you to change the symlink...

Launch it from the root of your project, where you can see src and target dirs.

The script search for classes with main method, offering a select to choose one (Example with mavenized JMeld project)

$ mvnexec 
 1) org.jmeld.ui.JMeldComponent
 2) org.jmeld.ui.text.FileDocument
 3) org.jmeld.JMeld
 4) org.jmeld.util.UIDefaultsPrint
 5) org.jmeld.util.PrintProperties
 6) org.jmeld.util.file.DirectoryDiff
 7) org.jmeld.util.file.VersionControlDiff
 8) org.jmeld.vc.svn.InfoCmd
 9) org.jmeld.vc.svn.DiffCmd
10) org.jmeld.vc.svn.BlameCmd
11) org.jmeld.vc.svn.LogCmd
12) org.jmeld.vc.svn.CatCmd
13) org.jmeld.vc.svn.StatusCmd
14) org.jmeld.vc.git.StatusCmd
15) org.jmeld.vc.hg.StatusCmd
16) org.jmeld.vc.bzr.StatusCmd
17) org.jmeld.Main
18) org.apache.commons.jrcs.tools.JDiff
#? 

If one is selected (typing number), you are prompt for arguments (you can avoid with mvnexec -P)

By default it compiles project every run. but you can avoid that using mvnexec -B

It allows to search only in test classes -M or --no-main, or only in main classes -T or --no-test. also has a filter by name option -f <whatever>

Hope this could save you some time, for me it does.

Give your input an ID and use the attr method:

var name = $("#id").attr("name");

Your problem seems unclear. You say you want to remove "a character from a certain position" then go on to say you want to remove a particular character.

If you only need to remove the first character you would do:

s = ":dfa:sif:e"
fixed = s[1:]

If you want to remove a character at a particular position, you would do:

s = ":dfa:sif:e"
fixed = s[0:pos]+s[pos+1:]

If you need to remove a particular character, say ':', the first time it is encountered in a string then you would do:

s = ":dfa:sif:e"
fixed = ''.join(s.split(':', 1))

int a = fork(); 

Creates a duplicate process "clone?", which shares the execution stack. The difference between the parent and the child is the return value of the function.

The child getting 0 returned, and the parent getting the new pid.

Each time the addresses and the values of the stack variables are copied. The execution continues at the point it already got to in the code.

At each fork, only one value is modified - the return value from fork.

just enter the following command on command prompt after launching the app:

adb shell dumpsys window windows | find "mCurrentFocus"

if executing the command on linux terminal replace find by grep

This problem can be simply solved by closing Eclipse and restarting it. Eclipse sometimes fails to establish a connection with the Emulator, so this can happen in some cases.

I have a raspberry pi, and I am using python web server (using Flask). I have tried everything above, the only solution is to close the terminal(shell) and open it again. Or restart the raspberry pi, because nothing stops that webserver...

Instead of WorksheetFunction.Vlookup, you can use Application.Vlookup. If you set a Variant equal to this it returns Error 2042 if no match is found. You can then test the variant - cellNum in this case - with IsError:

Sub test()
Dim ws As Worksheet: Set ws = Sheets("2012")
Dim rngLook As Range: Set rngLook = ws.Range("A:M")
Dim currName As String
Dim cellNum As Variant

'within a loop
currName = "Example"
cellNum = Application.VLookup(currName, rngLook, 13, False)
If IsError(cellNum) Then
    MsgBox "no match"
Else
    MsgBox cellNum
End If
End Sub

The Application versions of the VLOOKUP and MATCH functions allow you to test for errors without raising the error. If you use the WorksheetFunction version, you need convoluted error handling that re-routes your code to an error handler, returns to the next statement to evaluate, etc. With the Application functions, you can avoid that mess.

The above could be further simplified using the IIF function. This method is not always appropriate (e.g., if you have to do more/different procedure based on the If/Then) but in the case of this where you are simply trying to determinie what prompt to display in the MsgBox, it should work:

cellNum = Application.VLookup(currName, rngLook, 13, False)
MsgBox IIF(IsError(cellNum),"no match", cellNum)

Consider those methods instead of On Error ... statements. They are both easier to read and maintain -- few things are more confusing than trying to follow a bunch of GoTo and Resume statements.

This one was your solution.

$x = 0;
while($row = mysqli_fetch_array($result)) {             
    $posts[$x]['post_id'] = $row['post_id'];
    $posts[$x]['post_title'] = $row['post_title'];
    $posts[$x]['type'] = $row['type'];
    $posts[$x]['author'] = $row['author'];
    $x++;
}

In some developer-friendly ROMs you could just enable Root Access in Settings > Developer option > Root access. After that adb root becomes available. Unfortunately it does not work for most stock ROMs on the market.

You can also combine them I guess:

<!doctype html>
<html ng-app="myApp">
<head>
    <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
    <script src="http://code.angularjs.org/1.1.2/angular.min.js"></script>
    <script type="text/javascript">
        var myApp = angular.module('myApp', []);

        myApp.factory('myService', function() {
            return {
                foo: function() {
                    alert("I'm foo!");
                }
            };
        });

        myApp.run(function($rootScope, myService) {
            $rootScope.appData = myService;
        });

        myApp.controller('MainCtrl', ['$scope', function($scope){

        }]);

    </script>
</head>
<body ng-controller="MainCtrl">
    <button ng-click="appData.foo()">Call foo</button>
</body>
</html>

Another way would be to use .Net parser for HttpRequest. To do that you need to use a bit of reflection and simple class for WorkerRequest.

First create class that derives from HttpWorkerRequest (for simplicity you can use SimpleWorkerRequest):

public class MyWorkerRequest : SimpleWorkerRequest
{
    private readonly string _size;
    private readonly Stream _data;
    private string _contentType;

    public MyWorkerRequest(Stream data, string size, string contentType)
        : base("/app", @"c:\", "aa", "", null)
    {
        _size = size ?? data.Length.ToString(CultureInfo.InvariantCulture);
        _data = data;
        _contentType = contentType;
    }

    public override string GetKnownRequestHeader(int index)
    {
        switch (index)
        {
            case (int)HttpRequestHeader.ContentLength:
                return _size;
            case (int)HttpRequestHeader.ContentType:
                return _contentType;
        }
        return base.GetKnownRequestHeader(index);
    }

    public override int ReadEntityBody(byte[] buffer, int offset, int size)
    {
        return _data.Read(buffer, offset, size);
    }

    public override int ReadEntityBody(byte[] buffer, int size)
    {
        return ReadEntityBody(buffer, 0, size);
    }
}

Then wherever you have you message stream create and instance of this class. I'm doing it like that in WCF Service:

[WebInvoke(Method = "POST",
               ResponseFormat = WebMessageFormat.Json,
               BodyStyle = WebMessageBodyStyle.Bare)]
    public string Upload(Stream data)
    {
        HttpWorkerRequest workerRequest =
            new MyWorkerRequest(data,
                                WebOperationContext.Current.IncomingRequest.ContentLength.
                                    ToString(CultureInfo.InvariantCulture),
                                WebOperationContext.Current.IncomingRequest.ContentType
                );

And then create HttpRequest using activator and non public constructor

var r = (HttpRequest)Activator.CreateInstance(
            typeof(HttpRequest),
            BindingFlags.Instance | BindingFlags.NonPublic,
            null,
            new object[]
                {
                    workerRequest,
                    new HttpContext(workerRequest)
                },
            null);

var runtimeField = typeof (HttpRuntime).GetField("_theRuntime", BindingFlags.Static | BindingFlags.NonPublic);
if (runtimeField == null)
{
    return;
}

var runtime = (HttpRuntime) runtimeField.GetValue(null);
if (runtime == null)
{
    return;
}

var codeGenDirField = typeof(HttpRuntime).GetField("_codegenDir", BindingFlags.Instance | BindingFlags.NonPublic);
if (codeGenDirField == null)
{
    return;
}

codeGenDirField.SetValue(runtime, @"C:\MultipartTemp");

After that in r.Files you will have files from your stream.

Although most of these previous answers will work, I suggest you explore the provider or BloC architectures, both of which have been recommended by Google.

In short, the latter will create a stream that reports to widgets in the widget tree whenever a change in the state happens and it updates all relevant views regardless of where it is updated from.

Here is a good overview you can read to learn more about the subject: https://bloclibrary.dev/#/

The two top answers here suggest:

df.groupby(cols).agg(lambda x:x.value_counts().index[0])

or, preferably

df.groupby(cols).agg(pd.Series.mode)

However both of these fail in simple edge cases, as demonstrated here:

df = pd.DataFrame({
    'client_id':['A', 'A', 'A', 'A', 'B', 'B', 'B', 'C'],
    'date':['2019-01-01', '2019-01-01', '2019-01-01', '2019-01-01', '2019-01-01', '2019-01-01', '2019-01-01', '2019-01-01'],
    'location':['NY', 'NY', 'LA', 'LA', 'DC', 'DC', 'LA', np.NaN]
})

The first:

df.groupby(['client_id', 'date']).agg(lambda x:x.value_counts().index[0])

yields IndexError (because of the empty Series returned by group C). The second:

df.groupby(['client_id', 'date']).agg(pd.Series.mode)

returns ValueError: Function does not reduce, since the first group returns a list of two (since there are two modes). (As documented here, if the first group returned a single mode this would work!)

Two possible solutions for this case are:

import scipy
x.groupby(['client_id', 'date']).agg(lambda x: scipy.stats.mode(x)[0])

And the solution given to me by cs95 in the comments here:

def foo(x): 
    m = pd.Series.mode(x); 
    return m.values[0] if not m.empty else np.nan
df.groupby(['client_id', 'date']).agg(foo)

However, all of these are slow and not suited for large datasets. A solution I ended up using which a) can deal with these cases and b) is much, much faster, is a lightly modified version of abw33's answer (which should be higher):

def get_mode_per_column(dataframe, group_cols, col):
    return (dataframe.fillna(-1)  # NaN placeholder to keep group 
            .groupby(group_cols + [col])
            .size()
            .to_frame('count')
            .reset_index()
            .sort_values('count', ascending=False)
            .drop_duplicates(subset=group_cols)
            .drop(columns=['count'])
            .sort_values(group_cols)
            .replace(-1, np.NaN))  # restore NaNs

group_cols = ['client_id', 'date']    
non_grp_cols = list(set(df).difference(group_cols))
output_df = get_mode_per_column(df, group_cols, non_grp_cols[0]).set_index(group_cols)
for col in non_grp_cols[1:]:
    output_df[col] = get_mode_per_column(df, group_cols, col)[col].values

Essentially, the method works on one col at a time and outputs a df, so instead of concat, which is intensive, you treat the first as a df, and then iteratively add the output array (values.flatten()) as a column in the df.

This is a good exercise for yourself to work on :)

You should break your library into three parts

• Loading the CSV file
• Representing the file in memory so that you can modify it and read it
• Saving the CSV file back to disk

So you are looking at writing a CSVDocument class that contains:

• Load(const char* file);
• Save(const char* file);
• GetBody

So that you may use your library like this:

CSVDocument doc;
doc.Load("file.csv");
CSVDocumentBody* body = doc.GetBody();

CSVDocumentRow* header = body->GetRow(0);
for (int i = 0; i < header->GetFieldCount(); i++)
{
    CSVDocumentField* col = header->GetField(i);
    cout << col->GetText() << "\t";
}

for (int i = 1; i < body->GetRowCount(); i++) // i = 1 so we skip the header
{
    CSVDocumentRow* row = body->GetRow(i);
    for (int p = 0; p < row->GetFieldCount(); p++)
    {
        cout << row->GetField(p)->GetText() << "\t";
    }
    cout << "\n";
}

body->GetRecord(10)->SetText("hello world");

CSVDocumentRow* lastRow = body->AddRow();
lastRow->AddField()->SetText("Hey there");
lastRow->AddField()->SetText("Hey there column 2");

doc->Save("file.csv");

Which gives us the following interfaces:

class CSVDocument
{
public:
    void Load(const char* file);
    void Save(const char* file);

    CSVDocumentBody* GetBody();
};

class CSVDocumentBody
{
public:
    int GetRowCount();
    CSVDocumentRow* GetRow(int index);
    CSVDocumentRow* AddRow();
};

class CSVDocumentRow
{
public:
    int GetFieldCount();
    CSVDocumentField* GetField(int index);
    CSVDocumentField* AddField(int index);
};

class CSVDocumentField
{
public:
    const char* GetText();
    void GetText(const char* text);
};

Now you just have to fill in the blanks from here :)

Believe me when I say this - investing your time into learning how to make libraries, especially those dealing with the loading, manipulation and saving of data, will not only remove your dependence on the existence of such libraries but will also make you an all-around better programmer.

:)

EDIT

I don't know how much you already know about string manipulation and parsing; so if you get stuck I would be happy to help.

It's very important for accessibility reasons that you always specify value of the submit even if you are hiding this text, or if you use <input type="image" .../> to always specify alt="" attribute for this input field.

Blind people don't know what button will do if it doesn't contain meaningful alt="" or value="".

playSound is a static method in your class, but you are referring to members like audioSounds or minTime which are not declared static so they would require a SoundManager sm = new SoundManager(); to operate as sm.audioSounds or sm.minTime respectively

Solution:

public static List<AudioSource> audioSounds = new List<AudioSource>();
public static double minTime = 0.5;

Take a look at bash(1), you need a login shell to pickup the ~/.profile, i.e. the -l option.
