You can try git difftool, it is designed to do this stuff.

First, you need to config diff tool to vimdiff

git config diff.tool vimdiff

Then, when you want to diff, just use git difftool instead of git diff. It will work as you expect.

Aside from the ones you mention, I only use frequently when diffing the following:

• :diffupdate :diffu -> recalculate the diff, useful when after making several changes vim's isn't showing minimal changes anymore. Note that it only works if the files have been modified inside vimdiff. Otherwise, use:
  • :e to reload the files if they have been modified outside of vimdiff.
• :set noscrollbind -> temporarily disable simultaneous scrolling on both buffers, reenable by :set scrollbind and scrolling.

Most of what you asked for is folding: vim user manual's chapter on folding. Outside of diffs I sometime use:

• zo -> open fold.
• zc -> close fold.

But you'll probably be better served by:

• zr -> reducing folding level.
• zm -> one more folding level, please.

or even:

• zR -> Reduce completely the folding, I said!.
• zM -> fold Most!.

The other thing you asked for, use n lines of folding, can be found at the vim reference manual section on options, via the section on diff:

• set diffopt=<TAB>, then update or add context:n.

You should also take a look at the user manual section on diff.

I think you must also remove security auto config from your @SpringBootApplication annotated class:

@EnableAutoConfiguration(exclude = {
    org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration.class,
    org.springframework.boot.actuate.autoconfigure.ManagementSecurityAutoConfiguration.class})

On EF core you cannot create Indexes using data annotations.But you can do it using the Fluent API.

Like this inside your {Db}Context.cs:

protected override void OnModelCreating(ModelBuilder builder)
{
    builder.Entity<User>()
        .HasIndex(u => u.Email)
        .IsUnique();
}

...or if you're using the overload with the buildAction:

protected override void OnModelCreating(ModelBuilder builder)
{
    builder.Entity<User>(entity => {
        entity.HasIndex(e => e.Email).IsUnique();
    });
}

You can read more about it here : Indexes

The obvious thing to do is read the documentation.

But to help: substr($str, $start, $end);

$str is your text

$start is the character index to begin at. In your case, it is likely 0 which means the very beginning.

$end is where to truncate at. Suppose you wanted to end at 15 characters, for example. You would write it like this:

<?php

$text = "long text that should be truncated";
echo substr($text, 0, 15);

?>

and you would get this:

long text that 

makes sense?

EDIT

The link you gave is a function to find the last white space after chopping text to a desired length so you don't cut off in the middle of a word. However, it is missing one important thing - the desired length to be passed to the function instead of always assuming you want it to be 25 characters. So here's the updated version:

function truncate($text, $chars = 25) {
    if (strlen($text) <= $chars) {
        return $text;
    }
    $text = $text." ";
    $text = substr($text,0,$chars);
    $text = substr($text,0,strrpos($text,' '));
    $text = $text."...";
    return $text;
}

So in your case you would paste this function into the functions.php file and call it like this in your page:

$post = the_post();
echo truncate($post, 100);

This will chop your post down to the last occurrence of a white space before or equal to 100 characters. Obviously you can pass any number instead of 100. Whatever you need.

static_cast means that you can't accidentally const_cast or reinterpret_cast, which is a good thing.

I prefer an id descendant selector of your #form2, like this:

$("#form2 #name").val("Hello World!");

http://api.jquery.com/descendant-selector/

Normally I try to do whatever I can to avoid the use of cursors, but the following query will get you everything you need:

--Declare/Set required variables
DECLARE @vchDynamicDatabaseName AS VARCHAR(MAX),
        @vchDynamicQuery As VARCHAR(MAX),
        @DatabasesCursor CURSOR

SET @DatabasesCursor = Cursor FOR

--Select * useful databases on the server
SELECT name 
FROM sys.databases 
WHERE database_id > 4 
ORDER by name

--Open the Cursor based on the previous select
OPEN @DatabasesCursor
FETCH NEXT FROM @DatabasesCursor INTO @vchDynamicDatabaseName
WHILE @@FETCH_STATUS = 0
   BEGIN

   --Insert the select statement into @DynamicQuery 
   --This query will select the Database name, all tables/views and their columns (in a comma delimited field)
   SET @vchDynamicQuery =
   ('SELECT ''' + @vchDynamicDatabaseName + ''' AS ''Database_Name'',
          B.table_name AS ''Table Name'',
         STUFF((SELECT '', '' + A.column_name
               FROM ' + @vchDynamicDatabaseName + '.INFORMATION_SCHEMA.COLUMNS A
               WHERE A.Table_name = B.Table_Name
               FOR XML PATH(''''),TYPE).value(''(./text())[1]'',''NVARCHAR(MAX)'')
               , 1, 2, '''') AS ''Columns''
   FROM ' + @vchDynamicDatabaseName + '.INFORMATION_SCHEMA.COLUMNS B
   WHERE B.TABLE_NAME LIKE ''%%''
         AND B.COLUMN_NAME LIKE ''%%''
   GROUP BY B.Table_Name
   Order BY 1 ASC')

   --Print @vchDynamicQuery
   EXEC(@vchDynamicQuery)

   FETCH NEXT FROM @DatabasesCursor INTO @vchDynamicDatabaseName
END
CLOSE @DatabasesCursor
DEALLOCATE @DatabasesCursor
GO

I added a where clause in the main query (ex: B.TABLE_NAME LIKE ''%%'' AND B.COLUMN_NAME LIKE ''%%'') so that you can search for specific tables and/or columns if you want to.

Android parcable has some unique things. Those are given bellow:

1. You have to read Parcel as the same order where you put data on parcel.
2. Parcel will empty after read from parcel. That is if you have 3 data on your parcel. Then after read 3 times parcel will be empty.

Example: To make a class Parceble it must be implement Parceble. Percable has 2 method:

int describeContents();
void writeToParcel(Parcel var1, int var2);

Suppose you have a Person class and it has 3 field, firstName,lastName and age. After implementing Parceble interface. this interface is given bellow:

import android.os.Parcel;
import android.os.Parcelable;
public class Person implements Parcelable{
    private String firstName;
    private String lastName;
    private int age;

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public int getAge() {
        return age;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel parcel, int i) {
        parcel.writeString(firstName);
        parcel.writeString(lastName);
        parcel.writeInt(age);
    }

}

Here writeToParcel method we are writing/adding data on Parcel in an order. After this we have to add bellow code for reading data from parcel:

protected Person(Parcel in) {
        firstName = in.readString();
        lastName = in.readString();
        age = in.readInt();
    }

    public static final Creator<Person> CREATOR = new Creator<Person>() {
        @Override
        public Person createFromParcel(Parcel in) {
            return new Person(in);
        }

        @Override
        public Person[] newArray(int size) {
            return new Person[size];
        }
    };

Here, Person class is taking a parcel and getting data in same an order during writing.

Now during intent getExtra and putExtra code is given bellow:

Put in Extra:

Person person=new Person();
                person.setFirstName("First");
                person.setLastName("Name");
                person.setAge(30);

                Intent intent = new Intent(getApplicationContext(), SECOND_ACTIVITY.class);
                intent.putExtra()
                startActivity(intent); 

Get Extra:

Person person=getIntent().getParcelableExtra("person");

Full Person class is given bellow:

import android.os.Parcel;
import android.os.Parcelable;

public class Person implements Parcelable{
    private String firstName;
    private String lastName;
    private int age;



    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public int getAge() {
        return age;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel parcel, int i) {
        parcel.writeString(firstName);
        parcel.writeString(lastName);
        parcel.writeInt(age);
    }

    protected Person(Parcel in) {
        firstName = in.readString();
        lastName = in.readString();
        age = in.readInt();
    }

    public static final Creator<Person> CREATOR = new Creator<Person>() {
        @Override
        public Person createFromParcel(Parcel in) {
            return new Person(in);
        }

        @Override
        public Person[] newArray(int size) {
            return new Person[size];
        }
    };

}

Hope this will help you 
Thanks :)

SessionState

• Can be persisted in memory, which makes it a fast solution. Which means state cannot be shared in the Web Farm/Web Garden.
• Can be persisted in a Database, useful for Web Farms / Web Gardens.
• Is Cleared when the session dies - usually after 20min of inactivity.

ViewState

• Is sent back and forth between the server and client, taking up bandwidth.
• Has no expiration date.
• Is useful in a Web Farm / Web Garden

Sometimes two classes may have some parameter names in common. In that case, you can't pop the key-value pairs off of **kwargs or remove them from *args. Instead, you can define a Base class which unlike object, absorbs/ignores arguments:

class Base(object):
    def __init__(self, *args, **kwargs): pass

class A(Base):
    def __init__(self, *args, **kwargs):
        print "A"
        super(A, self).__init__(*args, **kwargs)

class B(Base):
    def __init__(self, *args, **kwargs):
        print "B"
        super(B, self).__init__(*args, **kwargs)

class C(A):
    def __init__(self, arg, *args, **kwargs):
        print "C","arg=",arg
        super(C, self).__init__(arg, *args, **kwargs)

class D(B):
    def __init__(self, arg, *args, **kwargs):
        print "D", "arg=",arg
        super(D, self).__init__(arg, *args, **kwargs)

class E(C,D):
    def __init__(self, arg, *args, **kwargs):
        print "E", "arg=",arg
        super(E, self).__init__(arg, *args, **kwargs)

print "MRO:", [x.__name__ for x in E.__mro__]
E(10)

yields

MRO: ['E', 'C', 'A', 'D', 'B', 'Base', 'object']
E arg= 10
C arg= 10
A
D arg= 10
B

Note that for this to work, Base must be the penultimate class in the MRO.

You're calling e.nextElement() twice inside your loop when you're only guaranteed that you can call it once without an exception. Rewrite the loop like so:

while(e.hasMoreElements()){
  String param = e.nextElement();
  System.out.println(param);
}

I have done experimentation on this.

It's true that System.gc(); only suggests to run the Garbage Collector.

But calling System.gc(); after setting all references to null, will improve performance and memory occupation.

All answers here - hacks. I've found better way to scroll collection view somewhere after relaodData:
Subclass collection view layout what ever layout you use, override method prepareLayout, after super call set what ever offset you need.
ex: https://stackoverflow.com/a/34192787/1400119

as per requested, here is the comment I gave earlier:

have a look at this:

• Vim integration to MonoDevelop for .net stuff at least..
• OmniCompletion

this link should help you if you want to use monodevelop on a MacOSX

Good luck and happy coding.

My simple answer was to turn the click bind into a function and call that from the onclick of the element - worked a treat! whereas none of the above did

There is a Win32 (C++) function in shlwapi.dll that does exactly what you want: PathRelativePathTo()

I'm not aware of any way to access this from .NET other than to P/Invoke it, though.

It can be done very easily in one step. You don't have to touch AndroidManifest. Instead do the following:

1. right click on the root folder of your project.
2. Click "Open Module Setting".
3. Go to the Flavours tab.
4. Change the applicationID to whatever package name you want. Press OK.

While you cannot expose a new port of an existing container, you can start a new container in the same Docker network and get it to forward traffic to the original container.

# docker run \
  --rm \
  -p $PORT:1234 \
  verb/socat \
    TCP-LISTEN:1234,fork \
    TCP-CONNECT:$TARGET_CONTAINER_IP:$TARGET_CONTAINER_PORT

Worked Example

Launch a web-service that listens on port 80, but do not expose its internal port 80 (oops!):

# docker run -ti mkodockx/docker-pastebin   # Forgot to expose PORT 80!

Find its Docker network IP:

# docker inspect 63256f72142a | grep IPAddress
                    "IPAddress": "172.17.0.2",

Launch verb/socat with port 8080 exposed, and get it to forward TCP traffic to that IP's port 80:

# docker run --rm -p 8080:1234 verb/socat TCP-LISTEN:1234,fork TCP-CONNECT:172.17.0.2:80

You can now access pastebin on http://localhost:8080/, and your requests goes to socat:1234 which forwards it to pastebin:80, and the response travels the same path in reverse.

Tests

On the Tests class we will add an @XmlRootElement annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData property differs from the default mapping we will use the @XmlElement annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted

package forum11221136;

import javax.xml.bind.annotation.*;

@XmlRootElement
public class Tests {

    TestData testData;

    @XmlElement(name="test-data")
    public TestData getTestData() {
        return testData;
    }

    public void setTestData(TestData testData) {
        this.testData = testData;
    }

}

TestData

On this class I used the @XmlType annotation to specify the order in which the elements should be ordered in. I added a testData property that appeared to be missing. I also used an @XmlElement annotation for the same reason as in the Tests class.

package forum11221136;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
    String title;
    String book;
    String count;
    List<TestData> testData;

    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getBook() {
        return book;
    }
    public void setBook(String book) {
        this.book = book;
    }
    public String getCount() {
        return count;
    }
    public void setCount(String count) {
        this.count = count;
    }
    @XmlElement(name="test-data")
    public List<TestData> getTestData() {
        return testData;
    }
    public void setTestData(List<TestData> testData) {
        this.testData = testData;
    }
}

Demo

Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.

package forum11221136;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Tests.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum11221136/input.xml");
        Tests tests = (Tests) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(tests, System.out);
    }

}

The original question is about Bootstrap 3 and that supports IE8 and 9 so Flexbox would be the best option but it's not part of my answer due the lack of support, see http://caniuse.com/#feat=flexbox and toggle the IE box. Pretty bad, eh?

2 ways:

1. Display-table: You can muck around with turning the row into a display:table and the col- into display:table-cell. It works buuuut the limitations of tables are there, among those limitations are the push and pull and offsets won't work. Plus, I don't know where you're using this -- at what breakpoint. You should make the image full width and wrap it inside another container to put the padding on there. Also, you need to figure out the design on mobile, this is for 768px and up. When I use this, I redeclare the sizes and sometimes I stick importants on them because tables take on the width of the content inside them so having the widths declared again helps this. You will need to play around. I also use a script but you have to change the less files to use it or it won't work responsively.

Here's a way to write watchers for nested properties:

    new Vue({
        ...allYourOtherStuff,
        watch: {
            ['foo.bar'](newValue, oldValue) {
                // Do stuff here
            }
        }
    });

You can even use this syntax for asynchronous watchers:

    new Vue({
        ...allYourOtherStuff,
        watch: {
            async ['foo.bar'](newValue, oldValue) {
                // Do stuff here
            }
        }
    });

There are two types of drop down lists available (I am not sure since which version).

ActiveX Drop Down
You can set the column widths, so your hidden column can be set to 0.

Form Drop Down
You could set the drop down range to a hidden sheet and reference the cell adjacent to the selected item. This would also work with the ActiveX type control.

How about "TIMESTAMPDIFF":

SELECT TIMESTAMPDIFF(SECOND,'2009-05-18','2009-07-29') from `post_statistics`

The official documentation of Dockerfile best practices does a great job explaining the differences. Dockerfile best practices

CMD:

The CMD instruction should be used to run the software contained by your image, along with any arguments. CMD should almost always be used in the form of CMD ["executable", "param1", "param2"…]. Thus, if the image is for a service, such as Apache and Rails, you would run something like CMD ["apache2","-DFOREGROUND"]. Indeed, this form of the instruction is recommended for any service-based image.

ENTRYPOINT:

The best use for ENTRYPOINT is to set the image’s main command, allowing that image to be run as though it was that command (and then use CMD as the default flags).

Well the thing is that you probably actually don't want the test to run indefinitely. You just want to wait a longer amount of time before the library decides the element doesn't exist. In that case, the most elegant solution is to use implicit wait, which is designed for just that:

driver.manage().timeouts().implicitlyWait( ... )

I wrote this method to replace characters or replace strings at a specific instance. instances start at 0 (this can easily be changed to 1 if you change the optional inst argument to 1, and test_instance variable to 1.

def replace_instance(some_word, str_to_replace, new_str='', inst=0):
    return_word = ''
    char_index, test_instance = 0, 0
    while char_index < len(some_word):
        test_str = some_word[char_index: char_index + len(str_to_replace)]
        if test_str == str_to_replace:
            if test_instance == inst:
                return_word = some_word[:char_index] + new_str + some_word[char_index + len(str_to_replace):]
                break
            else:
                test_instance += 1
        char_index += 1
    return return_word

Well it's been almost 9 years since I originally posted this and to be honest, Java has made a couple improvements since then. I'll leave my original answer below, but there's no need for people to do what is in it. 9 years ago, during code review I would have questioned why they did it and maybe approved it, maybe not. With modern lambdas available, it's irresponsible to have such a highly voted answer recommending an antiquated approach (that, in all fairness, was dubious to begin with...) In modern Java, that code review would be immediately rejected, and this would be suggested:

void foo(final String str) {
    Thread t = new Thread(() -> someFunc(str));
    t.start();
}

As before, details like handling that thread in a meaningful way is left as an exercise to the reader. But to put it bluntly, if you're afraid of using lambdas, you should be even more afraid of multi-threaded systems.

Original answer, just because:

You can declare a class right in the method

void Foo(String str) {
    class OneShotTask implements Runnable {
        String str;
        OneShotTask(String s) { str = s; }
        public void run() {
            someFunc(str);
        }
    }
    Thread t = new Thread(new OneShotTask(str));
    t.start();
}

Simple solution:

static void Main()
{
    List<string> myList = new List<string> { "Jason", "Bob", "Frank", "Bob" };
    myList.RemoveAll(x => x == "Bob");

    foreach (string s in myList)
    {
        //
    }
}

<string name="hello_world"><font fgcolor="red">Hello</font>
    </font fgcolor="blue">world!</font></string>

But note that this only works on a relatively short list of built-in colors: aqua, black, blue, fuchsia, green, grey, lime, maroon, navy, olive, purple, red, silver, teal, white, and yellow. See https://stackoverflow.com/a/31655150/338479 for a way to do it with arbitrary colors.

You might be using C:/[your-php-directory]/php.exe in Handler mapping of IIS just change it C:/[your-php-directory]/php-cgi.exe.

The package sciplot has the built-in function se(x)

appearance property doesn't work in all browser. You can do like the following-

input[type="radio"]{_x000D_
  display: none;_x000D_
}_x000D_
label:before{_x000D_
  content:url(http://strawberrycambodia.com/book/admin/templates/default/images/icons/16x16/checkbox.gif);_x000D_
}_x000D_
input[type="radio"]:checked+label:before{_x000D_
  content:url(http://www.treatment-abroad.ru/img/admin/icons/16x16/checkbox.gif);_x000D_
}

 _x000D_
  <input type="radio" name="gender" id="test1" value="male">_x000D_
  <label for="test1"> check 1</label>_x000D_
  <input type="radio" name="gender" value="female" id="test2">_x000D_
  <label for="test2"> check 2</label>_x000D_
  <input type="radio" name="gender" value="other" id="test3">_x000D_
  <label for="test3"> check 3</label>  

It works IE 8+ and other browsers

By default is private. Unless they're nested, classes are internal.

You need to see if the Type of your instance is equal to the Type of the class. To get the type of the instance you use the GetType() method:

 u.GetType().Equals(t);

or

 u.GetType.Equals(typeof(User));

should do it. Obviously you could use '==' to do your comparison if you prefer.

If you want to do it in the easiest shortcut, then u can do it with this plugin.

But this plugin is an alternate implementation using Bootstrap Modal. And real Bootstrap implementation is also very easy, so I don't like to use this plugin because it adds excess JS contents in the page, which will slow down the page loading time.

Idea

I like to implement it by myself by this way-

1. If user clicks on a button to delete an item from the list, then a JS call will put Item ID (or any more essential data) in a form in the modal.

2. Then in the pop-up, there will be 2 buttons for confirmation.

   • Yes will submit the form (with ajax or direct form submit)
   • No will just dismiss the modal

The code will be like this (using Bootstrap)-

<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">_x000D_
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>_x000D_

        //Say - $('p').get(0).id - this delete item id_x000D_
        $("#delete_item_id").val( $('p').get(0).id );_x000D_
        $('#delete_confirmation_modal').modal('show');_x000D_
    });_x000D_
});_x000D_
</script>_x000D_
_x000D_

    <div class="modal-content">_x000D_
   <div class="modal-header">_x000D_
    <button type="button" class="close" data-dismiss="modal">×</button>_x000D_
    <h4 class="modal-title">Do you really want to delete this Category?</h4>_x000D_
   </div>_x000D_
   <form role="form" method="post" action="category_delete" id="delete_data">_x000D_
    <input type="hidden" id="delete_item_id" name="id" value="12">_x000D_
    <div class="modal-footer">_x000D_
     <button type="submit" class="btn btn-danger">Yes</button>_x000D_

    </div>_x000D_
   </form>_x000D_
  </div>_x000D_
_x000D_
 </div>_x000D_
</div>

You should change the form action according to your requirement.

Happy coading :)

Here's a script to get foreign keys:

    SELECT TOP(150)
       t.[name] AS [Table],
       cols.[name] AS [Column],
       t2.[name] AS [Referenced Table],
       c2.[name] AS [Referenced Column],
       constr.[name] AS [Constraint]
  FROM sys.tables t
 INNER JOIN sys.foreign_keys constr ON constr.parent_object_id = t.object_id
 INNER JOIN sys.tables t2 ON t2.object_id = constr.referenced_object_id
 INNER JOIN sys.foreign_key_columns fkc ON fkc.constraint_object_id = constr.object_id
 INNER JOIN sys.columns cols ON cols.object_id = fkc.parent_object_id AND cols.column_id = fkc.parent_column_id
 INNER JOIN sys.columns c2 ON c2.object_id = fkc.referenced_object_id AND c2.column_id = fkc.referenced_column_id
 --WHERE t.[name] IN ('?', '?', ...)
 ORDER BY t.[Name], cols.[name]

On windows and Netbeans you can set the relative path as:

    new FileReader("src\\PACKAGE_NAME\\FILENAME");

On Linux and Netbeans you can set the relative path as:

    new FileReader("src/PACKAGE_NAME/FILENAME");

If you have your code inside Source Packages I do not know if it is the same for eclipse or other IDE

Try this:

MessageBox.Show("Some text", "Some title", 
    MessageBoxButtons.OK, MessageBoxIcon.Error);

You can basically switch the class using [ngClass]

for example

<button [ngClass]="{'active': selectedItem === 'item1'}" (click)="selectedItem = 'item1'">Button One</button>
<button [ngClass]="{'active': selectedItem === 'item2'}" (click)="selectedItem = 'item2'">Button Two</button>

You can use Node.js for Mobile Apps.

It works on Android devices and simulators, with pre-built binaries for armeabi-v7a, x86, arm64-v8a, x86_64. It also works on iOS, though that's outside the scope of this question.

Like JXcore, it is used to host a Node.js engine in the same process as the app, in a dedicated thread. Unlike JXcore, it is basically pure Node.js, built as a library, with a few portability fixes to run on Android. This means that it's much easier to keep the project up to date with mainline Node.js.

Plugins for Cordova and React Native are also available. The plugins provide a communication layer between the JavaScript side of those frameworks and the Node.js side. They also simplify development by taking care of a few things automatically, like packaging modules and cross-compiling native modules at build time.

Full disclosure: I work for the company that develops Node.js for Mobile Apps.

the most important thing is to analyze how roads, cities, blocks and buildings are structured. find out what all eg buildings have in common. look at photos, maps, plans and reality. if you do that you will be one step ahead of people who consider city building as a merely computer-technological matter.

next you should develop solutions on how to create that geometry in tiny, distinct steps. you have to define rules that make up a believable city. if you are into 3d modelling you have to rethink a lot of what you have learned so the computer can follow your instructions in any situation.

in order to not loose track you should set up a lot of operators that are only responsible for little parts of the whole process. that makes debugging, expanding and improving your system much easier. in the next step you should link those operators and check the results by changing parameters.

i have seen too many "city generators" that mainly consist of random-shaped boxes with some window textures on them : (

You can use the document compatibility mode to do this, which is what you were trying.. However, thing to note is: It must appear in the Web page's header (the HEAD section) before all other elements, except for the title element and other meta elements Hope that was the issue.. Also, The X-UA-compatible header is not case sensitive Refer: http://msdn.microsoft.com/en-us/library/cc288325%28v=vs.85%29.aspx#SetMode

Edit: in case something happens to kill the msdn link, here is the content:

Specifying Document Compatibility Modes

You can use document modes to control the way Internet Explorer interprets and displays your webpage. To specify a specific document mode for your webpage, use the meta element to include an X-UA-Compatible header in your webpage, as shown in the following example.

<html>
<head>
  <!-- Enable IE9 Standards mode -->
  <meta http-equiv="X-UA-Compatible" content="IE=9" >
  <title>My webpage</title>
</head>
<body>
  <p>Content goes here.</p>
</body>
</html> 

If you view this webpage in Internet Explorer 9, it will be displayed in IE9 mode.

The following example specifies EmulateIE7 mode.

<html>
<head>
  <!-- Mimic Internet Explorer 7 -->
  <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" >
  <title>My webpage</title>
</head>
<body>
  <p>Content goes here.</p>
</body>
</html> 

In this example, the X-UA-Compatible header directs Internet Explorer to mimic the behavior of Internet Explorer 7 when determining how to display the webpage. This means that Internet Explorer will use the directive (or lack thereof) to choose the appropriate document type. Because this page does not contain a directive, the example would be displayed in IE5 (Quirks) mode.

The title of the question asks about precision. BigDecimal distinguishes between scale and precision. Scale is the number of decimal places. You can think of precision as the number of significant figures, also known as significant digits.

Some examples in Clojure.

(.scale     0.00123M) ; 5
(.precision 0.00123M) ; 3

(In Clojure, The M designates a BigDecimal literal. You can translate the Clojure to Java if you like, but I find it to be more compact than Java!)

You can easily increase the scale:

(.setScale 0.00123M 7) ; 0.0012300M

But you can't decrease the scale in the exact same way:

(.setScale 0.00123M 3) ; ArithmeticException Rounding necessary

You'll need to pass a rounding mode too:

(.setScale 0.00123M 3 BigDecimal/ROUND_HALF_EVEN) ;
; Note: BigDecimal would prefer that you use the MathContext rounding
; constants, but I don't have them at my fingertips right now.

So, it is easy to change the scale. But what about precision? This is not as easy as you might hope!

It is easy to decrease the precision:

(.round 3.14159M (java.math.MathContext. 3)) ; 3.14M

But it is not obvious how to increase the precision:

(.round 3.14159M (java.math.MathContext. 7)) ; 3.14159M (unexpected)

For the skeptical, this is not just a matter of trailing zeros not being displayed:

(.precision (.round 3.14159M (java.math.MathContext. 7))) ; 6 
; (same as above, still unexpected)

FWIW, Clojure is careful with trailing zeros and will show them:

4.0000M ; 4.0000M
(.precision 4.0000M) ; 5

Back on track... You can try using a BigDecimal constructor, but it does not set the precision any higher than the number of digits you specify:

(BigDecimal. "3" (java.math.MathContext. 5)) ; 3M
(BigDecimal. "3.1" (java.math.MathContext. 5)) ; 3.1M

So, there is no quick way to change the precision. I've spent time fighting this while writing up this question and with a project I'm working on. I consider this, at best, A CRAZYTOWN API, and at worst a bug. People. Seriously?

So, best I can tell, if you want to change precision, you'll need to do these steps:

1. Lookup the current precision.
2. Lookup the current scale.
3. Calculate the scale change.
4. Set the new scale

These steps, as Clojure code:

(def x 0.000691M) ; the input number
(def p' 1) ; desired precision
(def s' (+ (.scale x) p' (- (.precision x)))) ; desired new scale
(.setScale x s' BigDecimal/ROUND_HALF_EVEN)
; 0.0007M

I know, this is a lot of steps just to change the precision!

Why doesn't BigDecimal already provide this? Did I overlook something?

There is no other way, so this is the best.

Edit: This answer is not valid since PHP 5.4 and higher.

Thanks,Bruno for giving me heads up on Common Name and Subject Alternative Name. As we figured out certificate was generated with CN with DNS name of network and asked for regeneration of new certificate with Subject Alternative Name entry i.e. san=ip:10.0.0.1. which is the actual solution.

But, we managed to find out a workaround with which we can able to run on development phase. Just add a static block in the class from which we are making ssl connection.

static {
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
        {
            public boolean verify(String hostname, SSLSession session)
            {
                // ip address of the service URL(like.23.28.244.244)
                if (hostname.equals("23.28.244.244"))
                    return true;
                return false;
            }
        });
}

If you happen to be using Java 8, there is a much slicker way of achieving the same result:

static {
    HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> hostname.equals("127.0.0.1"));
}

Replace

volume = (4 / 3) Math.PI * Math.pow(radius, 3);

With:

volume = (4 * Math.PI * Math.pow(radius, 3)) / 3;

Could it be that you are passing the data through get, not post?

Nginx-extra package is deprecated now.

The following therefore did now work for me as i tried installing various packages more_set_headers 'Server: My Very Own Server';

You can just do the following and no server or version information will be sent back

    server_tokens '';

if you just want to remove the version number this works

   server_tokens off;

The bin/XXX.apk file can be built automatically as soon as you save any source file:

Window/Preferences, Android/Build, uncheck "skip packaging and indexing..."

This will get ALL parameters from the request. For Debugging purposes only:

@RequestMapping (value = "/promote", method = {RequestMethod.POST, RequestMethod.GET})
public ModelAndView renderPromotePage (HttpServletRequest request) {
    Map<String, String[]> parameters = request.getParameterMap();

    for(String key : parameters.keySet()) {
        System.out.println(key);
        String[] vals = parameters.get(key);
        for(String val : vals)
            System.out.println(" -> " + val);
    }

    ModelAndView mv = new ModelAndView();
    mv.setViewName("test");
    return mv;
}

No, prior to Oracle version 12.2, identifiers are not allowed to exceed 30 characters in length. See the Oracle SQL Language Reference.

However, from version 12.2 they can be up to 128 bytes long. (Note: bytes, not characters).

• .length is a field, containing the capacity (NOT the number of elements the array contains at the moment) of arrays.

• length() is a method used by Strings (amongst others), it returns the number of chars in the String; with Strings, capacity and number of containing elements (chars) have the same value.

• size() is a method implemented by all members of Collection (lists, sets, stacks,...). It returns the number of elements (NOT the capacity; some collections even don´t have a defined capacity) the collection contains.

You can simply use DataColumnCollection.IndexOf

So that you can get the index of the required column by name then use it with your row:

row[dt.Columns.IndexOf("ColumnName")] = columnValue;

It's showing the backslash because you're also escaping the backslash.

Aside from double quotes, you must also escape backslashes if you want to include one in your JSON quoted string. However if you intend to use a backslash in an escape sequence, obviously you shouldn't escape it.

Try rewriting your success handler to:

success : handleData

The success property of the ajax method only requires a reference to a function.

In your handleData function you can take up to 3 parameters:

object data
string textStatus
jqXHR jqXHR

{
      for (int i = 0; i < dataGridView1.Columns.Count; i++)

Depending on your need you can use one of following method:

• In first line/s of view add "using your.domainName;" (if it is required in specific view only)

• if required in all subsequent views then add "using your.domainName;" in _ViewStart.cshtml. You can find more about this in: Where and how is the _ViewStart.cshtml layout file linked?

• Or add Assembly reference in View web.config as described by others explained in: How do you implement a @using across all Views in Asp.Net MVC 3?

Boost is a good suggestion. But if you would like to roll your own, it's not so hard.

Basically you just need a way to build up a graph of objects and then output them to some structured storage format (JSON, XML, YAML, whatever). Building up the graph is as simple as utilizing a marking recursive decent object algorithm and then outputting all the marked objects.

I wrote an article describing a rudimentary (but still powerful) serialization system. You may find it interesting: Using SQLite as an On-disk File Format, Part 2.

I had an issue with the proposed solutions, using lookup does not always return the expected value.

This is due to DNS caching, the value of the call is cached and intead of doing a proper call on the next try it gives back the cached value. Of course this is an issue here as it means if you lose connectivity and call lookup it could still return the cached value as if you had internet, and conversely, if you reconnect your internet after lookup returned null it will still return null for the duration of the cache, which can be a few minutes, even if you do have internet now.

TL;DR: lookup returning something does not necessarily mean you have internet, and it not returning anything does not necessarily mean you don't have internet. It is not reliable.

I implemented the following solution by taking inspiration from the data_connection_checker plugin:

 /// If any of the pings returns true then you have internet (for sure). If none do, you probably don't.
  Future<bool> _checkInternetAccess() {
    /// We use a mix of IPV4 and IPV6 here in case some networks only accept one of the types.
    /// Only tested with an IPV4 only network so far (I don't have access to an IPV6 network).
    final List<InternetAddress> dnss = [
      InternetAddress('8.8.8.8', type: InternetAddressType.IPv4), // Google
      InternetAddress('2001:4860:4860::8888', type: InternetAddressType.IPv6), // Google
      InternetAddress('1.1.1.1', type: InternetAddressType.IPv4), // CloudFlare
      InternetAddress('2606:4700:4700::1111', type: InternetAddressType.IPv6), // CloudFlare
      InternetAddress('208.67.222.222', type: InternetAddressType.IPv4), // OpenDNS
      InternetAddress('2620:0:ccc::2', type: InternetAddressType.IPv6), // OpenDNS
      InternetAddress('180.76.76.76', type: InternetAddressType.IPv4), // Baidu
      InternetAddress('2400:da00::6666', type: InternetAddressType.IPv6), // Baidu
    ];

    final Completer<bool> completer = Completer<bool>();

    int callsReturned = 0;
    void onCallReturned(bool isAlive) {
      if (completer.isCompleted) return;

      if (isAlive) {
        completer.complete(true);
      } else {
        callsReturned++;
        if (callsReturned >= dnss.length) {
          completer.complete(false);
        }
      }
    }

    dnss.forEach((dns) => _pingDns(dns).then(onCallReturned));

    return completer.future;
  }

  Future<bool> _pingDns(InternetAddress dnsAddress) async {
    const int dnsPort = 53;
    const Duration timeout = Duration(seconds: 3);

    Socket socket;
    try {
      socket = await Socket.connect(dnsAddress, dnsPort, timeout: timeout);
      socket?.destroy();
      return true;
    } on SocketException {
      socket?.destroy();
    }
    return false;
  }

The call to _checkInternetAccess takes at most a duration of timeout to complete (3 seconds here), and if we can reach any of the DNS it will complete as soon as the first one is reached, without waiting for the others (as reaching one is enough to know you have internet). All the calls to _pingDns are done in parallel.

It seems to work well on an IPV4 network, and when I can't test it on an IPV6 network (I don't have access to one) I think it should still work. It also works on release mode builds, but I yet have to submit my app to Apple to see if they find any issue with this solution.

It should also work in most countries (including China), if it does not work in one you can add a DNS to the list that is accessible from your target country.

if you open the psql console in a terminal window, by typing

$ psql

you're super user username will be shown before the =#, for example:

elisechant=#$

That will be the user name you should use for localhost.

Is it possible that the date could actually be outside that range? Does it come from user input? If the answer to either of these questions is yes, then you should always check - otherwise you're leaving your application prone to error.

You can format your date for inclusion in an SQL statement rather easily:

var sqlFormattedDate = myDateTime.Date.ToString("yyyy-MM-dd HH:mm:ss");

Sometimes, although you add <uses-permission android:name="android.permission.INTERNET" /> in the AndroidManifest and you have a WiFi connection, this exception can be thrown. In my case, I have turned off WiFi and then turned it on again. This resolved the error. Weird solution, but sometimes it works.

I find the accepted answer, and all the others strange, since they pass self to an abstract class. An abstract class is not instantiated so can't have a self.

So try this, it works.

from abc import ABCMeta, abstractmethod


class Abstract(metaclass=ABCMeta):
    @staticmethod
    @abstractmethod
    def foo():
        """An abstract method. No need to write pass"""


class Derived(Abstract):
    def foo(self):
        print('Hooray!')


FOO = Derived()
FOO.foo()

If you try appending the number like, say listName.append(4) , this will append 4 at last. But if you are trying to take <int> and then append it as, num = 4 followed by listName.append(num), this will give you an error as 'num' is of <int> type and listName is of type <list>. So do type cast int(num) before appending it.

A DFD shows how the data moves through a system, a flowchart is closer to the operations that system does.

In the classic make a cup of tea example, a DFD would show where the water, tea, milk, sugar were going, whereas the flowchart shows the process.

$('input.yourClass:checkbox:checked').each(function () {
    var sThisVal = $(this).val();
});

This would get all checkboxes of the class name "yourClass". I like this example since it uses the jQuery selector checked instead of doing a conditional check. Personally I would also use an array to store the value, then use them as needed, like:

var arr = [];
$('input.yourClass:checkbox:checked').each(function () {
    arr.push($(this).val());
});

To get e.g the value from column 'test' and row 1 it works like

df[['test']].values[0][0]

as only df[['test']].values[0] gives back a array

How about a simple 2 liner:

def humanizeFileSize(filesize):
    p = int(math.floor(math.log(filesize, 2)/10))
    return "%.3f%s" % (filesize/math.pow(1024,p), ['B','KiB','MiB','GiB','TiB','PiB','EiB','ZiB','YiB'][p])

Here is how it works under the hood:

1. Calculates log₂(filesize)
2. Divides it by 10 to get the closest unit. (eg if size is 5000 bytes, the closest unit is Kb, so the answer should be X KiB)
3. Returns file_size/value_of_closest_unit along with unit.

It however doesn't work if filesize is 0 or negative (because log is undefined for 0 and -ve numbers). You can add extra checks for them:

def humanizeFileSize(filesize):
    filesize = abs(filesize)
    if (filesize==0):
        return "0 Bytes"
    p = int(math.floor(math.log(filesize, 2)/10))
    return "%0.2f %s" % (filesize/math.pow(1024,p), ['Bytes','KiB','MiB','GiB','TiB','PiB','EiB','ZiB','YiB'][p])

Examples:

>>> humanizeFileSize(538244835492574234)
'478.06 PiB'
>>> humanizeFileSize(-924372537)
'881.55 MiB'
>>> humanizeFileSize(0)
'0 Bytes'

NOTE - There is a difference between Kb and KiB. KB means 1000 bytes, whereas KiB means 1024 bytes. KB,MB,GB are all multiples of 1000, whereas KiB, MiB, GiB etc are all multiples of 1024. More about it here

Expanding on the method pointed to at docs.djangoproject.com:

class MyForm(forms.Form): 
    comment = forms.CharField(
            widget=forms.TextInput(attrs={'size':'40'}))

I thought it was troublesome to have to know the native widget type for every field, and thought it funny to override the default just to put a class name on a form field. This seems to work for me:

class MyForm(forms.Form): 
    #This instantiates the field w/ the default widget
    comment = forms.CharField()

    #We only override the part we care about
    comment.widget.attrs['size'] = '40'

This seems a little cleaner to me.

You could also do what I do and by a commercial control like this one: http://www.syncfusion.com/products/reporting-edition/xlsio

I have been struging for years before ending with a commercial solution. I first tried the OLEDB approach that is very easy to use in my development environment but can be a knightmare to deploy. Then I tried the open source solutions but most of the are outdated and have bad support.

The xlsio controls from syncfusion are just the ones I use and are happy with but others exists. If you can affort it, do not hesitate, it's the best solution. Why? Because it has no dependencies with the system and supports all version of office right away. Among other advantages like, it's really fast.

And no, I do not work for synfusion ;)

It depends on how you want to use it. Using a Join is one way. Another way of doing it is let the thread notify the caller of the thread by using an event. For instance when you have your graphical user interface (GUI) thread that calls a process which runs for a while and needs to update the GUI when it finishes, you can use the event to do this. This website gives you an idea about how to work with events:

http://msdn.microsoft.com/en-us/library/aa645739%28VS.71%29.aspx

Remember that it will result in cross-threading operations and in case you want to update the GUI from another thread, you will have to use the Invoke method of the control which you want to update.

If you hafe upload your file in media than:

media
example-input-file.txt

views.py

def download_csv(request):    
    file_path = os.path.join(settings.MEDIA_ROOT, 'example-input-file.txt')    
    if os.path.exists(file_path):    
        with open(file_path, 'rb') as fh:    
            response = HttpResponse(fh.read(), content_type="application/vnd.ms-excel")    
            response['Content-Disposition'] = 'inline; filename=' + os.path.basename(file_path)    
            return response

urls.py

path('download_csv/', views.download_csv, name='download_csv'),

download.html

a href="{% url 'download_csv' %}" download=""

To be honest, the comments accompanying the prototypes seem clear enough. Something like this should do the trick:

void compute_md5(char *str, unsigned char digest[16]) {
    MD5Context ctx;
    MD5Init(&ctx);
    MD5Update(&ctx, str, strlen(str));
    MD5Final(digest, &ctx);
}

where str is a C string you want the hash of, and digest is the resulting MD5 digest.

To achieve this just use an Intent using the constant ACTION_SETTINGS, specifically defined to show the System Settings:

startActivity(new Intent(Settings.ACTION_SETTINGS));

startActivityForResult() is optional, only if you want to return some data when the settings activity is closed.

startActivityForResult(new Intent(Settings.ACTION_SETTINGS), 0);

here you can find a list of contants to show specific settings or details of an aplication.

If you want to automatically/periodically clean up exited containers and remove images and volumes that aren't in use by a running container you can download the Docker image meltwater/docker-cleanup.

That way you don't need to go clean it up by hand.

Just run:

docker run -d -v /var/run/docker.sock:/var/run/docker.sock:rw  -v /var/lib/docker:/var/lib/docker:rw --restart=unless-stopped meltwater/docker-cleanup:latest

It will run every 30 minutes (or however long you set it using DELAY_TIME=1800 option) and clean up exited containers and images.

More details: https://github.com/meltwater/docker-cleanup/blob/master/README.md

I reached the point that I set, up to max_iter=1200000 on my LinearSVC classifier, but still the "ConvergenceWarning" was still present. I fix the issue by just setting dual=False and leaving max_iter to its default.

With LogisticRegression(solver='lbfgs') classifier, you should increase max_iter. Mine have reached max_iter=7600 before the "ConvergenceWarning" disappears when training with large dataset's features.

'continue' is used within looping structures to skip the rest of the current loop iteration and continue execution at the condition evaluation and then the beginning of the next iteration.

'break' ends execution of the current for, foreach, while, do-while or switch structure.

break accepts an optional numeric argument which tells it how many nested enclosing structures are to be broken out of.

Check out the following links:

http://www.php.net/manual/en/control-structures.break.php

I just want to notice that startActivity from outside an activity is valid in some android versions (between N and O-MR1) and the interesting point is that it is a bug in android source code!

This is the comment above startActivity implementation. See here.

Calling start activity from outside an activity without FLAG_ACTIVITY_NEW_TASK is generally not allowed, except if the caller specifies the task id the activity should be launched in. A bug was existed between N and O-MR1 which allowed this to work.

$.getJSON is an asynchronous request, meaning the code will continue to run even though the request is not yet done. You should trigger the second request when the first one is done, one of the choices you seen already in ComFreek's answer.

Alternatively you could use jQuery's $.when/.then(), similar to this:

var input = "netuetamundis";  var sID;  $(document).ready(function () {     $.when($.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/" + input + "?api_key=API_KEY_HERE", function () {         obj = name;         sID = obj.id;         console.log(sID);     })).then(function () {         $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function (stats) {             console.log(stats);         });     }); }); 

This would be more open for future modification and separates out the responsibility for the first call to know about the second call.

The first call can simply complete and do it's own thing not having to be aware of any other logic you may want to add, leaving the coupling of the logic separated.

Try this simple solution:

In your activity implement onBackPressed

 @Override
    public void onBackPressed() {
       if (getSupportFragmentManager().getBackStackEntryCount() > 1) {
            getSupportFragmentManager().popBackStack();
        } else {
            finish();
        }
    }

This will work if you want to pop the top fragment on each back press. Note:- While adding fragment to activity always do add the transaction to back stack for this to work

Starting with 0.21.0, using .loc or [] with a list with one or more missing labels is deprecated in favor of .reindex. So, the answer to your question is:

df1 = df.reindex(columns=['b','c'])

In prior versions, using .loc[list-of-labels] would work as long as at least one of the keys was found (otherwise it would raise a KeyError). This behavior is deprecated and now shows a warning message. The recommended alternative is to use .reindex().

I use them sparingly, but they can be pretty convenient:

def log(msg):
   log.logfile.write(msg)

Now I can use log throughout my module, and redirect output simply by setting log.logfile. There are lots and lots of other ways to accomplish that, but this one's lightweight and dirt simple. And while it smelled funny the first time I did it, I've come to believe that it smells better than having a global logfile variable.

You 'can' do it ... but it's not very wise ... this is about as daring as I'll try ... as far as full RegEx support your much better off using perl or the like.

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

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

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

- (IBAction) triggerActionWithSender: (id) sender;

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

@property(retain) IBOutlet UIButton *someButton;

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

The subject of the certificate is the entity its public key is associated with (i.e. the "owner" of the certificate).

As RFC 5280 says:

The subject field identifies the entity associated with the public key stored in the subject public key field. The subject name MAY be carried in the subject field and/or the subjectAltName extension.

X.509 certificates have a Subject (Distinguished Name) field and can also have multiple names in the Subject Alternative Name extension.

The Subject DN is made of multiple relative distinguished names (RDNs) (themselves made of attribute assertion values) such as "CN=yourname" or "O=yourorganization".

In the context of the article you're linking to, the subject would be the user/owner of the cert.

Use %in% as follows

A$C %in% B$C

Which will tell you which values of column C of A are in B.

What is returned is a logical vector. In the specific case of your example, you get:

A$C %in% B$C
# [1]  TRUE FALSE  TRUE  TRUE

Which you can use as an index to the rows of A or as an index to A$C to get the actual values:

# as a row index
A[A$C %in% B$C,  ]  # note the comma to indicate we are indexing rows

# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4  # returns all values of A$C that are in B$C

We can negate it too:

A$C[!A$C %in% B$C]
[1] 2   # returns all values of A$C that are NOT in B$C

  2 %in% B$C   # "is the value 2 in B$C ?"  
  # FALSE

  A$C[2] %in% B$C  # "is the 2nd element of A$C in B$C ?"  
  # FALSE

Try using

git push --set-upstream origin <branch_name>

Otherwise

use

git push -u 

will tell you what needs to be done.

In my case, I'm on Windows and following the answer by Cameron above only works if you use the full name of the ndk-build which is ndk-build.cmd. I have to clean and rebuild the project, then restart the emulator before getting the app to work (Actually I imported the sample HelloJni from NDK, into Android Studio). However, make sure the path to NDK does not contain space.

Finally, my build.gradle is full listed as below:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.example.hellojni"
        minSdkVersion 4
        targetSdkVersion 4

        ndk {
            moduleName "hello-jni"
        }

        testApplicationId "com.example.hellojni.tests"
        testInstrumentationRunner "android.test.InstrumentationTestRunner"
    }
    sourceSets.main {
        jni.srcDirs = [] // This prevents the auto generation of Android.mk
//        sourceSets.main.jni.srcDirs = []
        jniLibs.srcDir 'src/main/libs' // This is not necessary unless you have precompiled libraries in your project.
    }

    task buildNative(type: Exec, description: 'Compile JNI source via NDK') {
        def ndkDir = android.plugin.ndkFolder
        commandLine "$ndkDir/ndk-build.cmd",
                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source
                '-j', Runtime.runtime.availableProcessors(),
                'all',
                'NDK_DEBUG=1'
    }

    task cleanNative(type: Exec, description: 'Clean JNI object files') {

Already answered above, but here's another approach you could take. I can't find the original post I adapted this from, but here's the code for the sake of your question. As noted above, the flatMap() function is what you'd be looking to utilize with Java 8. You can throw it in a utility class and just call "RandomUtils.combine(list1, list2, ...);" and you'd get a single List with all values. Just be careful with the wildcard - you could change this if you want a less generic method. You can also modify it for Sets - you just have to take care when using flatMap() on Sets to avoid data loss from equals/hashCode methods due to the nature of the Set interface.

Edit - If you use a generic method like this for the Set interface, and you happen to use Lombok, make sure you understand how Lombok handles equals/hashCode generation.

  /**
    * Combines multiple lists into a single list containing all elements of
    * every list.
    * 
    * @param <T> - The type of the lists.
    * @param lists - The group of List implementations to combine
    * @return a single List<?> containing all elements of the passed in lists.
    */
   public static <T> List<?> combine(final List<?>... lists) {
      return Stream.of(lists).flatMap(List::stream).collect(Collectors.toList());
   }

You can use operator.setitem.

from operator import setitem
a = [5, 4, 3, 2, 1, 0]
ell = [0, 1, 3, 5]
m = [0, 0, 0, 0]
for b, c in zip(ell, m):
    setitem(a, b, c)
>>> a
[0, 0, 3, 0, 1, 0]

Is it any more readable or efficient than your solution? I am not sure!

I know it's a bit old but I ran in the same problem today. I wanted to install eclipse on my vm with xubuntu. Because I've had problems with the latest eclipse version 2019-06 I tried with Oxygen. So I went to eclipse.org and downloaded oxygen. When running oxygen, the problem with merketplace not reachable occurs. So I downloaded the eclipse installer not immediatly the oxygen. After that I can use eclipse as expectet ( all versions)

As I could understand the question is not about how pass a string with control symbols using json but how to store and restore json in file where you can split a string with editor control symbols.

If you want to store multiline string in a file then your file will not store the valid json object. But if you use your json files in your program only, then you can store the data as you wanted and remove all newlines from file manually each time you load it to your program and then pass to json parser.

Or, alternatively, which would be better, you can have your json data source files where you edit a sting as you want and then remove all new lines with some utility to the valid json file which your program will use.

The + operator returns the numeric representation of the object. So in your particular case, it would appear to be predicating the if on whether or not d is a non-zero number.

Reference here. And, as pointed out in comments, here.

In my case below code

    <?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:top="10dp" android:bottom="-10dp"
        >

        <shape android:shape="rectangle">
            <solid android:color="@color/maincolor" />

            <corners
                android:topLeftRadius="10dp"
                android:topRightRadius="10dp"
                android:bottomLeftRadius="0dp"
                android:bottomRightRadius="0dp"
            />
        </shape>

    </item>
    </layer-list>

You can use:

var dictionary = myList.ToDictionary(x => x);

The \includegraphics function has a page option for inserting a specific page of a PDF file as graphs. The default is one, but you can change it.

\includegraphics[scale=0.75,page=2]{multipage.pdf}

You can find more here.

Is there a js listener for when a user scrolls in a certain textbox that can be used?

DOM L3 UI Events spec gave the initial definition but is considered obsolete.

To add a single handler you can do:

  let isTicking;
  const debounce = (callback, evt) => {
    if (isTicking) return;
    requestAnimationFrame(() => {
      callback(evt);
      isTicking = false;
    });
    isTicking = true;
  };
  const handleScroll = evt => console.log(evt, window.scrollX, window.scrollY);
  document.defaultView.onscroll = evt => debounce(handleScroll, evt);

For multiple handlers or, if preferable for style reasons, you may use addEventListener as opposed to assigning your handler to onscroll as shown above.

If using something like _.debounce from lodash you could probably get away with:

const handleScroll = evt => console.log(evt, window.scrollX, window.scrollY);
document.defaultView.onscroll = evt => _.debounce(() => handleScroll(evt));

Review browser compatibility and be sure to test on some actual devices before calling it done.

I had a problem with this error as well, turned out the the filename was causing the problem.

I was calling it like this: Application.Run "'" & strPath & strFName & "'!UPC.PrintaFew"

The variable strFName contained an apostrophe in it which, of course messed things up. Took me hours to figure it out. But once the apostrophe was removed from the filename it worked.

Yes, this is confusing...

According to this blog post, it looks like this is an omission from WPF.

To make it work you need to use a style:

    <Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
        <Border.Style>
            <Style>
                <Setter Property="Border.Background" Value="Blue"/>
                <Style.Triggers>
                    <Trigger Property="Border.IsMouseOver" Value="True">
                        <Setter Property="Border.Background" Value="Green" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </Border.Style>
        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
    </Border>

I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.

In simple English from GROUP BY with two parameters what we are doing is looking for similar value pairs and get the count to a 3rd column.

Look at the following example for reference. Here I'm using International football results from 1872 to 2020

Explanation: The meaning of the first row is there were 11 Friendly tournaments held on Southern Rhodesia in total.

Note: Here it's mandatory to use a counter column in this case.

"Z" doesn't stand for "Zulu"

I don't have any more information than the Wikipedia article cited by the two existing answers, but I believe the interpretation that "Z" stands for "Zulu" is incorrect. UTC time is referred to as "Zulu time" because of the use of Z to identify it, not the other way around. The "Z" seems to have been used to mark the time zone as the "zero zone", in which case "Z" unsurprisingly stands for "zero" (assuming the following information from Wikipedia is accurate):

Around 1950, a letter suffix was added to the zone description, assigning Z to the zero zone, and A–M (except J) to the east and N–Y to the west (J may be assigned to local time in non-nautical applications — zones M and Y have the same clock time but differ by 24 hours: a full day). These can be vocalized using the NATO phonetic alphabet which pronounces the letter Z as Zulu, leading to the use of the term "Zulu Time" for Greenwich Mean Time, or UT1 from January 1, 1972 onward.

Can't you just send to INADDR_BROADCAST? Admittedly, that'll send on all interfaces - but that's rarely a problem.

Otherwise, ioctl and SIOCGIFBRDADDR should get you the address on *nix, and WSAioctl and SIO_GET_BROADCAST_ADDRESS on win32.

For a method that works with both C and C++, you might want to consider using the standard library function strtol().

#include <cstdlib>
#include <iostream>
using namespace std;

int main() {
    string s = "abcd";
    char * p;
    long n = strtol( s.c_str(), & p, 16 );
    if ( * p != 0 ) { //my bad edit was here
        cout << "not a number" << endl;
    }
    else {
        cout << n << endl;
    }
}

Try instead of db.parse(xml):

Document doc = db.parse(new InputSource(new StringReader(**xml**)));

On macOS Mojave 10.14.4, you can also try Command ? + Q in a terminal.

You can solve this problem by using AJAX. You don't need to load JQuery for AJAX but it has a better error and success handling than native JS.

I would do it like so:

1) add an click eventlistener to all my anchors on the page. 2) on click, you can setup an ajax-request to your php, in the POST-DATA you set the anchor id or the text-value 3) the php gets the value and you can setup a request to your database. Then you return the value which you need and echo it to the ajax-request. 4) your success function of the ajax-request is doing some stuff

For more information about ajax-requests look back here:

-> Ajax-Request NATIVE https://blog.garstasio.com/you-dont-need-jquery/ajax/

A simple JQuery examle:

$("button").click(function(){
  $.ajax({url: "demo_test.txt", success: function(result){
    $("#div1").html(result);
  }});
});

This is how did it works like a charm.

CSS

#loader {
position:fixed;
left:1px;
top:1px;
width: 100%;
height: 100%;
z-index: 9999;

background: url('../images/ajax-loader100X100.gif') 50% 50% no-repeat rgb(249,249,249);
}  

in _layout file inside body tag but outside the container div. Every time page loads it shows loading. Once page is loaded JS fadeout(second)

<div id="loader">
</div>

JS at the bottom of _layout file

<script type="text/javascript">
// With the element initially shown, we can hide it slowly:
 $("#loader").fadeOut(1000);
</script>  

Here is what I use when I don't have access to the source string, e.g. for downloaded HTML:

// replace newlines with <br>
public static String replaceNewlinesWithBreaks(String source) {
    return source != null ? source.replaceAll("(?:\n|\r\n)","<br>") : "";
}

For XML you should probably edit that to replace with <br/> instead.

Example of its use in a function (additional calls removed for clarity):

// remove HTML tags but preserve supported HTML text styling (if there is any)
public static CharSequence getStyledTextFromHtml(String source) {
    return android.text.Html.fromHtml(replaceNewlinesWithBreaks(source));
}

...and a further example:

textView.setText(getStyledTextFromHtml(someString));

You can use as below :

.width100 {_x000D_
  max-width: 100px;_x000D_
  height: 100px;_x000D_
  width: auto;_x000D_
  border: solid red;_x000D_
}

<img src="https://www.gravatar.com/avatar/dc48e9b92e4210d7a3131b3ef46eb8b1?s=512&d=identicon&r=PG" class="width100" />

This should do it:

<div id="wrap">
  <div id="nav"></div>
  <div id="content"></div>
  <div style="clear:both"></div>
</div>

Both are technically correct. If you look at the source code for .equals(), it simply defers to ==.

I use ==, however, as that will be null safe.

You can interactively stash single lines with git stash -p (analogous to git add -p).

It doesn't take a filename, but you could just skip other files with d until you reached the file you want stashed and the stash all changes in there with a.

The IF/THEN/ELSE construct you are using is only valid in stored procedures and functions. Your query will need to be restructured because you can't use the IF() function to control the flow of the WHERE clause like this.

The IF() function that can be used in queries is primarily meant to be used in the SELECT portion of the query for selecting different data based on certain conditions, not so much to be used in the WHERE portion of the query:

SELECT IF(JQ.COURSE_ID=0, 'Some Result If True', 'Some Result If False'), OTHER_COLUMNS
FROM ...
WHERE ...

Posting parameters Using POST:-

URL url;
URLConnection urlConn;
DataOutputStream printout;
DataInputStream  input;
url = new URL (getCodeBase().toString() + "env.tcgi");
urlConn = url.openConnection();
urlConn.setDoInput (true);
urlConn.setDoOutput (true);
urlConn.setUseCaches (false);
urlConn.setRequestProperty("Content-Type","application/json");   
urlConn.setRequestProperty("Host", "android.schoolportal.gr");
urlConn.connect();  
//Create JSONObject here
JSONObject jsonParam = new JSONObject();
jsonParam.put("ID", "25");
jsonParam.put("description", "Real");
jsonParam.put("enable", "true");

The part which you missed is in the the following... i.e., as follows..

// Send POST output.
printout = new DataOutputStream(urlConn.getOutputStream ());
printout.writeBytes(URLEncoder.encode(jsonParam.toString(),"UTF-8"));
printout.flush ();
printout.close ();

The rest of the thing you can do it.

Change the port number which port are available in your system By following ways

1. First open the Apache “httpd.conf” file:

#Listen 12.34.56.78:80
Listen 80
ServerName localhost:80

to

#Listen 12.34.56.78:8080
Listen 8080
ServerName localhost:8080

2. Open httpd-ssl.conf:

Listen 443
<VirtualHost _default_:443>

to

Listen 441
<VirtualHost _default_:441>

3. Follow the trick. Now “Start” Apache and if everything goes well, your Apache server should start up.

The difference between from datetime import datetime and normal import datetime is that , you are dealing with a module at one time and a class at other.

The strptime function only exists in the datetime class so you have to import the class with the module otherwise you have to specify datetime twice when calling this function.

The thing here is that , the class name and the module name has been given the same name so it creates a bit of confusuion.

There should be an event logged in the EventVwr (Warning from asp.net), which could provide you more details on where the error could be.

RewriteEngine on
RewriteBase /basic_test/

RewriteRule ^index.php$ test.php

I'm assuming from the way you worded the question that you want to change the size after the page has rendered?

In Javascript, you can manipulate DOM CSS properties, for example:

document.getElementById('textboxid').style.height="200px";
document.getElementById('textboxid').style.fontSize="14pt";

If you simply want to specify the height and font size, use CSS or style attributes, e.g.

//in your CSS file or <style> tag
#textboxid
{
    height:200px;
    font-size:14pt;
}

<!--in your HTML-->
<input id="textboxid" ...>

Or

<input style="height:200px;font-size:14pt;" .....>

When use method delete in form then must have to set route delete

Route::delete("empresas/eliminar/{id}", "CompaniesController@delete");

Here's what I got based on other answers. A little overkill on getting so specific with the error handling.

public static T GetPropertyValue<T>(object sourceInstance, string targetPropertyName, bool throwExceptionIfNotExists = false)
{
    string errorMsg = null;

    try
    {
        if (sourceInstance == null || string.IsNullOrWhiteSpace(targetPropertyName))
        {
            errorMsg = $"Source object is null or property name is null or whitespace. '{targetPropertyName}'";
            Log.Warn(errorMsg);

            if (throwExceptionIfNotExists)
                throw new ArgumentException(errorMsg);
            else
                return default(T);
        }

        Type returnType = typeof(T);
        Type sourceType = sourceInstance.GetType();

        PropertyInfo propertyInfo = sourceType.GetProperty(targetPropertyName, returnType);
        if (propertyInfo == null)
        {
            errorMsg = $"Property name '{targetPropertyName}' of type '{returnType}' not found for source object of type '{sourceType}'";
            Log.Warn(errorMsg);

            if (throwExceptionIfNotExists)
                throw new ArgumentException(errorMsg);
            else
                return default(T);
        }

        return (T)propertyInfo.GetValue(sourceInstance, null);
    }
    catch(Exception ex)
    {
        errorMsg = $"Problem getting property name '{targetPropertyName}' from source instance.";
        Log.Error(errorMsg, ex);

        if (throwExceptionIfNotExists)
            throw;
    }

    return default(T);
}

First of all it is not recommended to have php files with functions in design folder. You should create a new module or extend (copy from core to local a helper and add function onto that class) and do not change files from app/code/core.

To answer to your question you can use:

require(Mage::getBaseDir('design').'/frontend/default/mytheme/myfunc.php');

Best practice (as a start) will be to create in /app/code/local/Mage/Core/Helper/Extra.php a php file:

<?php
class Mage_Core_Helper_Extra extends Mage_Core_Helper_Abstract
{

    public function getSomething()
    {
        return 'Someting';
    }

}

And to use it in phtml files use:

$this->helper('core/extra')->getSomething();

Or in all the places:

Mage::helper('core/extra')->getSomething();

Im going to provide an argument against using socket.io.

I think using socket.io solely because it has fallbacks isnt a good idea. Let IE8 RIP.

In the past there have been many cases where new versions of NodeJS has broken socket.io. You can check these lists for examples... https://github.com/socketio/socket.io/issues?q=install+error

If you go to develop an Android app or something that needs to work with your existing app, you would probably be okay working with WS right away, socket.io might give you some trouble there...

Plus the WS module for Node.JS is amazingly simple to use.

You can always take the CTE, (Common Tabular Expression), approach.

;WITH updateCTE AS
(
    SELECT ID, TITLE 
    FROM HOLD_TABLE
    WHERE ID = 101
)

UPDATE updateCTE
SET TITLE = 'TEST';

SELECT StaffId,(Title+''+FirstName+''+LastName) AS FullName 
FROM StaffInformation

Where do you write with in the brackets this will be appear in the one single column. Where do you want a dot into the middle of the Title and First Name write syntax below,

SELECT StaffId,(Title+'.'+FirstName+''+LastName) AS FullName 
FROM StaffInformation

These syntax works with MS SQL Server 2008 R2 Express Edition.

Running in a Docker container introduced a whole slew of additional problems for connecting so hopefully this helps someone. I ended up needed to add the following options which I'll explain below:

-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=${DOCKER_HOST_IP}
-Dcom.sun.management.jmxremote.port=9999
-Dcom.sun.management.jmxremote.rmi.port=9998

DOCKER_HOST_IP

Unlike using jconsole locally, you have to advertise a different IP than you'll probably see from within the container. You'll need to replace ${DOCKER_HOST_IP} with the externally resolvable IP (DNS Name) of your Docker host.

JMX Remote & RMI Ports

It looks like JMX also requires access to a remote management interface (jstat) that uses a different port to transfer some data when arbitrating the connection. I didn't see anywhere immediately obvious in jconsole to set this value. In the linked article the process was:

• Try and connect from jconsole with logging enabled
• Fail
• Figure out which port jconsole attempted to use
• Use iptables/firewall rules as necessary to allow that port to connect

While that works, it's certainly not an automatable solution. I opted for an upgrade from jconsole to VisualVM since it let's you to explicitly specify the port on which jstatd is running. In VisualVM, add a New Remote Host and update it with values that correlate to the ones specified above:

Then right-click the new Remote Host Connection and Add JMX Connection...

Don't forget to check the checkbox for Do not require SSL connection. Hopefully, that should allow you to connect.

You can use the --table or -t option, which will output a nice looking set of results

echo 'desc table_name' | mysql -uroot database -t

or some other method to pass a query to mysql, like:

mysql -uroot table_name --table < /tmp/somequery.sql

output:

Sorry for I did not explain my answer really well at beginning. There is another way to add an new column to an existing dataframe. 1st step, make a new empty data frame (with all the columns in your data frame, plus a new or few columns you want to add) called df_temp 2nd step, combine the df_temp and your data frame.

df_temp = pd.DataFrame(columns=(df_null.columns.tolist() + ['empty']))
df = pd.concat([df_temp, df])

It might be the best solution, but it is another way to think about this question.

the reason of I am using this method is because I am get this warning all the time:

: SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead

See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
  df["empty1"], df["empty2"] = [np.nan, ""]

great I found the way to disable the Warning

pd.options.mode.chained_assignment = None 

The quick possible answer: When you first successfully clone an empty git repository, the origin has no master branch. So the first time you have a commit to push you must do:

git push origin master

Which will create this new master branch for you. Little things like this are very confusing with git.

If this didn't fix your issue then it's probably a gitolite-related issue:

Your conf file looks strange. There should have been an example conf file that came with your gitolite. Mine looks like this:

Please make sure you're setting your conf file correctly.

Gitolite actually replaces the gitolite user's account with a modified shell that doesn't accept interactive terminal sessions. You can see if gitolite is working by trying to ssh into your box using the gitolite user account. If it knows who you are it will say something like "Hi XYZ, you have access to the following repositories: X, Y, Z" and then close the connection. If it doesn't know you, it will just close the connection.

Lastly, after your first git push failed on your local machine you should never resort to creating the repo manually on the server. We need to know why your git push failed initially. You can cause yourself and gitolite more confusion when you don't use gitolite exclusively once you've set it up.

A git push will try and push all local branches to the remote server, this is likely what you do not want. I have a couple of conveniences setup to deal with this:

Alias "gpull" and "gpush" appropriately:

In my ~/.bash_profile

get_git_branch() {
  echo `git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'`
}
alias gpull='git pull origin `get_git_branch`'
alias gpush='git push origin `get_git_branch`'

Thus, executing "gpush" or "gpull" will push just my "currently on" branch.

At least in the current versions of PHPMailers, there's a function clearReplyTos() to empty the reply-to array.

    $mail->ClearReplyTos();
    $mail->addReplyTo([email protected], 'EXAMPLE');

I also got the same error and I did clean build and it worked.

try setting the display to block in your javascript instead of a blank value.

You can use this library, which both initially sizes your iframe correctly and also keeps it at the right size by detecting whenever the size of the iframe's content changes (either via regular checking in a setInterval or via MutationObserver) and resizing it.

GRANT ALL PRIVILEGES ON DATABASE "my_db" to my_user;

Here is a simple example taken from 'Modern C++ Design - Generic Programming and Design Patterns Applied' by Andrei Alexandrescu:

He uses a classes with template template parameters in order to implement the policy pattern:

// Library code
template <template <class> class CreationPolicy>
class WidgetManager : public CreationPolicy<Widget>
{
   ...
};

He explains: Typically, the host class already knows, or can easily deduce, the template argument of the policy class. In the example above, WidgetManager always manages objects of type Widget, so requiring the user to specify Widget again in the instantiation of CreationPolicy is redundant and potentially dangerous.In this case, library code can use template template parameters for specifying policies.

The effect is that the client code can use 'WidgetManager' in a more elegant way:

typedef WidgetManager<MyCreationPolicy> MyWidgetMgr;

Instead of the more cumbersome, and error prone way that a definition lacking template template arguments would have required:

typedef WidgetManager< MyCreationPolicy<Widget> > MyWidgetMgr;

A monad is an array of functions

(Pst: an array of functions is just a computation).

Actually, instead of a true array (one function in one cell array) you have those functions chained by another function >>=. The >>= allows to adapt the results from function i to feed function i+1, perform calculations between them or, even, not to call function i+1.

The types used here are "types with context". This is, a value with a "tag". The functions being chained must take a "naked value" and return a tagged result. One of the duties of >>= is to extract a naked value out of its context. There is also the function "return", that takes a naked value and puts it with a tag.

An example with Maybe. Let's use it to store a simple integer on which make calculations.

-- a * b
multiply :: Int -> Int -> Maybe Int
multiply a b = return  (a*b)

-- divideBy 5 100 = 100 / 5
divideBy :: Int -> Int -> Maybe Int
divideBy 0 _ = Nothing -- dividing by 0 gives NOTHING
divideBy denom num = return (quot num denom) -- quotient of num / denom

-- tagged value
val1 = Just 160 

-- array of functions feeded with val1
array1 = val1 >>= divideBy 2  >>= multiply 3 >>= divideBy  4 >>= multiply 3

-- array of funcionts created with the do notation
-- equals array1 but for the feeded val1
array2 :: Int -> Maybe Int
array2 n = do
       v <- divideBy 2  n
       v <- multiply 3 v
       v <- divideBy 4 v
       v <- multiply 3 v
       return v

-- array of functions, 
-- the first >>= performs 160 / 0, returning Nothing
-- the second >>= has to perform Nothing >>= multiply 3 ....
-- and simply returns Nothing without calling multiply 3 ....
array3 = val1 >>= divideBy 0  >>= multiply 3 >>= divideBy  4 >>= multiply 3

main = do
     print array1
     print (array2 160)
     print array3

Just to show that monads are array of functions with helper operations, consider the equivalent to the above example, just using a real array of functions

type MyMonad = [Int -> Maybe Int] -- my monad as a real array of functions

myArray1 = [divideBy 2, multiply 3, divideBy 4, multiply 3]

-- function for the machinery of executing each function i with the result provided by function i-1
runMyMonad :: Maybe Int -> MyMonad -> Maybe Int
runMyMonad val [] = val
runMyMonad Nothing _ = Nothing
runMyMonad (Just val) (f:fs) = runMyMonad (f val) fs

And it would be used like this:

print (runMyMonad (Just 160) myArray1)

If you stick to HTML structure and proper selectors according to the Bootstrap convention, you should be alright.

DEMO

I was facing the same issue for a couple of days then I figure out that the Oracle.DataAccess is available in the references list of the project, but in the bin folder is missing. So I removed it from the references list and readded again.

In combination of answers of @Cassian and @Hllitec and from https://stackoverflow.com/a/42706309/1001717 here my solution, where I put (only!) the checksum value into a variable for further processing:

for /f "delims=" %i in ('certutil -v -hashfile myPackage.nupkg SHA256 ^| find /i /v "sha256" ^| find /i /v "certutil"') do set myVar=%i

To test the output you can add a piped echo command with the var:

for /f "delims=" %i in ('certutil -v -hashfile myPackage.nupkg SHA256 ^| find /i /v "sha256" ^| find /i /v "certutil"') do set myVar=%i | echo %myVar%

A bit off-topic, but FYI: I used this before uploading my NuGet package to Artifactory. BTW. as alternative you can use JFrog CLI, where checksum is calculated automatically.

It’s less confusing to always use an escaped hyphen, so that it doesn't have to be positionally dependent. That’s a \- inside the bracketed character class.

But there’s something else to consider. Some of those enumerated characters should possibly be written differently. In some circumstances, they definitely should.

This comparison of regex flavors says that C? can use some of the simpler Unicode properties. If you’re dealing with Unicode, you should probably use the general category \p{L} for all possible letters, and maybe \p{Nd} for decimal numbers. Also, if you want to accomodate all that dash punctuation, not just HYPHEN-MINUS, you should use the \p{Pd} property. You might also want to write that sequence of whitespace characters simply as \s, assuming that’s not too general for you.

All together, that works out to apattern of [\p{L}\p{Nd}\p{Pd}!$*] to match any one character from that set.

I’d likely use that anyway, even if I didn’t plan on dealing with the full Unicode set, because it’s a good habit to get into, and because these things often grow beyond their original parameters. Now when you lift it to use in other code, it will still work correctly. If you hard-code all the characters, it won’t.

For me, the following steps worked:

1. Open the eclipse.ini file

2. Change

   -Xms40m
   -Xmx512m
   

   to

   -Xms512m
   -Xmx1024m
   

3. Restart Eclipse

See here

in AndroidManifest.xml set theme holo like this:

<activity
android:name="your Fragment or activity"
android:label="@string/xxxxxx"
android:theme="@android:style/Theme.Holo" >

The error:

'\r': command not found

is caused by shell not able to recognise Windows-like CRLF line endings (0d 0a) as it expects only LF (0a).

Git

If you using Git on Windows, make sure you selected 'Checkout as-is' during setup. Then make sure that you run: git config --global core.autocrlf false, so Git will not perform any conversions when checking out or committing text files.

dos2unix

If you're not using Git, you simply need to convert these affected files/scripts back into Unix-like line endings (LF), either by:

dos2unix ~/.bashrc

^{Note: The dos2unix command is part of dos2unix package.}

Ex/Vim editor + tr

If you've Vim installed, the following command should correct the files:

ex +'bufdo! %! tr -d \\r' -scxa ~/.bash*

^{Useful alias: alias dos2unix="ex +'bufdo! %! tr -d \\\\r' -scxa".}

tr

Here is the method by using tr:

cat ~/.bashrc | tr -d '\r' > ~/.bashrc.fixed && mv -v ~/.bashrc.fixed ~/.bashrc

or:

tr -d '\r' < filename > new_filename

^{Note: The \r is equivalent to \015.}

sed

You can try the following command:

sed -i'.bak' s/\r//g ~/.bash*

recode

The following aliases can be useful (which replaces dos2unix command):

alias unix2dos='recode lat1:ibmpc'
alias dos2unix='recode ibmpc:lat1'

^{Source: Free Unix Tools (ssh, bash, etc) under Windows.}

perl

The following perl command can convert the file from DOS into Unix format:

perl -p -i.bak -e 's/\015//g' ~/.bash*

^{Source: stripping the ^M.}

tofrodos

On Linux, like Ubuntu which doesn’t come standard with either dos2unix or unix2dos, you can install tofrodos package (sudo apt-get install tofrodos), and define the following aliases:

alias dos2unix=’fromdos’
alias unix2dos=’todos’

Then use in the same syntax as above.

Vagrant

If you're using Vagrant VM and this happens for provisioning script, try setting binary option to true:

# Shell provisioner, see: https://www.vagrantup.com/docs/provisioning/shell.html
config.vm.provision "shell" do |s|
  s.binary = true # Replace Windows line endings with Unix line endings.
  s.path = "script.sh"
end

See: Windows CRLF to Unix LF Issues in Vagrant.

I prefer not to alter the path hierarchy, but instead deal with git specifically...knowing that I'm never going to use old git to do what new git will now manage. This is a brute force solution.

NOTE: I installed XCode on Yosemite (10.10.2) clean first.

I then installed from the binary available on git-scm.com.

$ which git
/usr/bin/git
$ cd /usr/bin
$ sudo ln -sf /usr/local/git/bin/git
$ sudo ln -sf /usr/local/git/bin/git-credential-osxkeychain
$ sudo ln -sf /usr/local/git/bin/git-cvsserver
$ sudo ln -sf /usr/local/git/bin/git-receive-pack
$ sudo ln -sf /usr/local/git/bin/git-shell
$ sudo ln -sf /usr/local/git/bin/git-upload-archive
$ sudo ln -sf /usr/local/git/bin/git-upload-pack
$ ls -la
(you should see your new symlinks)

Here is one way...

(Get-Process powershell | select -First 1).Path

Here is possibly a better way, as it returns the first hit on the path, just like if you had ran Powershell from a command prompt...

(Get-Command powershell.exe).Definition

-moz-box-pack:center;
-moz-box-align:center;

/* Safari, Opera, and Chrome */
display:-webkit-box;
-webkit-box-pack:center;

Here's how I do file upload in react using axios

import React from 'react'
import axios, { post } from 'axios';

class SimpleReactFileUpload extends React.Component {

  constructor(props) {
    super(props);
    this.state ={
      file:null
    }
    this.onFormSubmit = this.onFormSubmit.bind(this)
    this.onChange = this.onChange.bind(this)
    this.fileUpload = this.fileUpload.bind(this)
  }

  onFormSubmit(e){
    e.preventDefault() // Stop form submit
    this.fileUpload(this.state.file).then((response)=>{
      console.log(response.data);
    })
  }

  onChange(e) {
    this.setState({file:e.target.files[0]})
  }

  fileUpload(file){
    const url = 'http://example.com/file-upload';
    const formData = new FormData();
    formData.append('file',file)
    const config = {
        headers: {
            'content-type': 'multipart/form-data'
        }
    }
    return  post(url, formData,config)
  }

  render() {
    return (
      <form onSubmit={this.onFormSubmit}>
        <h1>File Upload</h1>
        <input type="file" onChange={this.onChange} />
        <button type="submit">Upload</button>
      </form>
   )
  }
}



export default SimpleReactFileUpload

The easiest way is probably to use xvfb-run:

DISPLAY=:1 xvfb-run java -jar selenium-server-standalone-2.0b3.jar

xvfb-run does the whole X authority dance for you, give it a try!

@DougW has clearly answered this question, but I still like to add some codes here to explain Doug's points. (And correct errors in the code above)

Solution 1: URL-encode the POST data with a content-type header :application/x-www-form-urlencoded .

Note: you do not need to urlencode $_POST[] fields one by one, http_build_query() function can do the urlencoding job nicely.

$fields = array(
    'mediaupload'=>$file_field,
    'username'=>$_POST["username"],
    'password'=>$_POST["password"],
    'latitude'=>$_POST["latitude"],
    'longitude'=>$_POST["longitude"],
    'datetime'=>$_POST["datetime"],
    'category'=>$_POST["category"],
    'metacategory'=>$_POST["metacategory"],
    'caption'=>$_POST["description"]
);

$fields_string = http_build_query($fields);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);

Solution 2: Pass the array directly as the post data without URL-encoding, while the Content-Type header will be set to multipart/form-data.

$fields = array(
        'mediaupload'=>$file_field,
        'username'=>$_POST["username"],
        'password'=>$_POST["password"],
        'latitude'=>$_POST["latitude"],
        'longitude'=>$_POST["longitude"],
        'datetime'=>$_POST["datetime"],
        'category'=>$_POST["category"],
        'metacategory'=>$_POST["metacategory"],
        'caption'=>$_POST["description"]
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_POST,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$fields);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $response = curl_exec($ch);

Both code snippets work, but using different HTTP headers and bodies.

from https://git-scm.com/book/en/v2/Git-Tools-Advanced-Merging

This will basically do a fake merge. It will record a new merge commit with both branches as parents, but it will not even look at the branch you’re merging in. It will simply record as the result of the merge the exact code in your current branch.

$ git merge -s ours mundo

Merge made by the 'ours' strategy.

$ git diff HEAD HEAD~

You can see that there is no difference between the branch we were on and the result of the merge.

This can often be useful to basically trick Git into thinking that a branch is already merged when doing a merge later on. For example, say you branched off a release branch and have done some work on it that you will want to merge back into your master branch at some point. In the meantime some bugfix on master needs to be backported into your release branch. You can merge the bugfix branch into the release branch and also merge -s ours the same branch into your master branch (even though the fix is already there) so when you later merge the release branch again, there are no conflicts from the bugfix.

A situation I've found to be useful if I want master to reflect the changes of a new topic branch. I've noticed that -Xtheirs doesn't merge without conflicts in some circumstances... e.g.

$ git merge -Xtheirs topicFoo 

CONFLICT (modify/delete): js/search.js deleted in HEAD and modified in topicFoo. Version topicFoo of js/search.js left in tree.

In this case the solution I found was

$ git checkout topicFoo

from topicFoo, first merge in master using the -s ours strategy, this will create the fake commit that is just the state of topicFoo. $ git merge -s ours master

check the created merge commit

$ git log

now checkout the master branch

$ git checkout master

merge the topic branch back but this time use the -Xtheirs recursive strategy, this will now present you with a master branch with the state of topicFoo.

$ git merge -X theirs topicFoo

A non-jquery version that works in both webkit and gecko:

var keyboardEvent = document.createEvent('KeyboardEvent');
var initMethod = typeof keyboardEvent.initKeyboardEvent !== 'undefined' ? 'initKeyboardEvent' : 'initKeyEvent';

keyboardEvent[initMethod](
  'keydown', // event type: keydown, keyup, keypress
  true, // bubbles
  true, // cancelable
  window, // view: should be window
  false, // ctrlKey
  false, // altKey
  false, // shiftKey
  false, // metaKey
  40, // keyCode: unsigned long - the virtual key code, else 0
  0, // charCode: unsigned long - the Unicode character associated with the depressed key, else 0
);
document.dispatchEvent(keyboardEvent);

Use String.matches(), like:

String myString = "qwerty123456";
System.out.println(myString.matches("[A-Za-z0-9]+"));

That may not be the absolute "fastest" possible approach. But in general there's not much point in trying to compete with the people who write the language's "standard library" in terms of performance.

You can access user data directly in the twig template without requesting anything in the controller. The user is accessible like that : app.user.

Now, you can access every property of the user. For example, you can access the username like that : app.user.username.

Warning, if the user is not logged, the app.user is null.

If you want to check if the user is logged, you can use the is_granted twig function. For example, if you want to check if the user has ROLE_ADMIN, you just have to do is_granted("ROLE_ADMIN").

So, in every of your pages you can do :

{% if is_granted("ROLE") %}
    Hi {{ app.user.username }}
{% endif %}

Use setTimeout(drawAll, 20) instead. That only executes the function once.

Here's one way. You have to get the individual components from the date object (day, month & year) and then build and format the string however you wish.

n =  new Date();_x000D_
y = n.getFullYear();_x000D_
m = n.getMonth() + 1;_x000D_
d = n.getDate();_x000D_
document.getElementById("date").innerHTML = m + "/" + d + "/" + y;

<p id="date"></p>

        var ratio = (double)longString.Length / chunkLength;
        var countOfChunks = Convert.ToByte(Math.Round(ratio, MidpointRounding.ToPositiveInfinity));

        for (byte i = 0; i < countOfChunks; i++)
        {
            var remainingLength = longString.Length - chunkLength * i;
            if (chunkLength > remainingLength)
                chunks.Add(longString.Substring(i * chunkLength, remainingLength));
            else
                chunks.Add(longString.Substring(i * chunkLength, chunkLength));
        }

With a little PowerShell script:

sqlcmd -Q "set nocount on select top 0 * from [DB].[schema].[table]" -o c:\temp\header.txt_x000D_
bcp [DB].[schema].[table] out c:\temp\query.txt -c -T -S BRIZA_x000D_
Get-Content c:\temp\*.txt | Set-Content c:\temp\result.txt_x000D_
Remove-Item c:\temp\header.txt_x000D_
Remove-Item c:\temp\query.txt

Warning: The concatenation follows the .txt file name (in alphabetical order)

An alternative way using Vim(Vi compatible):

Delete duplicate, consecutive lines from a file:

vim -esu NONE +'g/\v^(.*)\n\1$/d' +wq

Delete duplicate, nonconsecutive and nonempty lines from a file:

vim -esu NONE +'g/\v^(.+)$\_.{-}^\1$/d' +wq

The bookmarks extension mentioned in the accepted answer conflicts with toggling breakpoints via the margin.

You could do the same with breakpoints and select the debug tab on the left to see them listed. Better yet, use File, Preferences, Keyboard Shortcuts and set (Shift+)Ctrl+F9 to navigate between them, even across files:

You can just use either of the following approaches:

.center-block {
  margin: auto;
  display: block;
}

<div>
  <input class="center-block">
</div>

.parent {
  display: grid;
  place-items: center;
}

<div class="parent">
  <input>
</div>

OpenGL is bundled with Visual Studio. You just need to install GLUT package (freeglut would be fine), which can be found in NuGet.

Open your solution, click TOOLS->NuGet Package Manager->Package Manager Console to open a NuGet console, type Install-Package freeglut.

For VS 2013, use nupengl.core package instead.

It's 2020 now. Use VCPKG.

Taking the answer above as guidance;

I made an extra graph for "hours worked by month", then copy/special-pasted it as a 'linked picture' for use under my other graphs. in other words, I copy pasted my existing graphs over the linked picture made from my new graph with the new axis.. And because it is a linked picture it always updates.

Make it easy on yourself though, make sure you copy an existing graph to build your 'picture' graph - then delete the series or change the data source to what you need as an extra axis. That way you won't have to mess around resizing.

The results were not too bad considering what I wanted to achieve; basically a list of incident frequency bar graph, with a performance tread line, and then a solid 'backdrop' of hours worked.

Thanks to the guy above for the idea!

best way copy the ? symbol and paste it.

Use this:

var arr = $('input:checkbox:checked').map(function () {
  return this.value;
}).get();

I have also faced the problem. In the php file, I have written following code where there was some space before php start tag

<?php
namespace App\Controller;

when I remove that space, it solved.

How can I accomplish that?

Your example declares a TypeScript < 1.5 internal module, which is now called a namespace. The old module App {} syntax is now equivalent to namespace App {}. As a result, the following works:

// test.ts
export namespace App {
    export class SomeClass {
        getName(): string {
            return 'name';
        }
    }
}

// main.ts
import { App } from './test';
var a = new App.SomeClass();

That being said...

Try to avoid exporting namespaces and instead export modules (which were previously called external modules). If needs be you can use a namespace on import with the namespace import pattern like this:

// test.ts
export class SomeClass {
    getName(): string {
        return 'name';
    }
}

// main.ts
import * as App from './test'; // namespace import pattern
var a = new App.SomeClass();

In addition to all of the other answers, if you are sending HTML emails that contain URLs as linking text, make sure that the URL matches the linking text. I know that Thunderbird automatically flags them as being a scam if not.

The wrong way:

Go to your account now: <a href="http://www.paypal.com.phishers-anonymous.org/">http://www.paypal.com</a>

The right way:

Go to your account now: <a href="http://www.yourdomain.org/">http://www.yourdomain.org</a>

Or use an unrelated linking text instead of a URL:

<a href="http://www.yourdomain.org/">Click here to go to your account</a>

In addition to the other answers, you can use this less-known method to grab elements of a certain parent like so,

$('child', 'parent');

In your case, that would be

if ($(event.target, 'div#hello')[0]) console.log(`${event.target.tagName} is an offspring of div#hello`);

Note the use of commas between the child and parent and their separate quotation marks. If they were surrounded by the same quotes

$('child, parent');

you'd have an object containing both objects, regardless of whether they exist in their document trees.

I have found a useful article that also explains the topic quite clearly and easy language. Link is JSONP

Some of the worth noting points are:

1. JSONP pre-dates CORS.
2. It is a pseudo-standard way to retreive data from a different domain,
3. It has limited CORS features (only GET method)

Working is as follows:

1. <script src="url?callback=function_name"> is included in the html code
2. When step 1 gets executed it sens a function with the same function name (as given in the url parameter) as a response.
3. If the function with the given name exists in the code, it will be executed with the data, if any, returned as an argument to that function.

Open the workbook as hidden and then set it as "saved" so that users are not prompted when they close out.

Dim w As Workbooks

Private Sub Workbook_Open()
    Application.ScreenUpdating = False
    Set w = Workbooks
    w.Open Filename:="\\server\PriceList.xlsx", UpdateLinks:=False, ReadOnly:=True 'this is the data file were going to be opening
    ActiveWindow.Visible = False
    ThisWorkbook.Activate
    Application.ScreenUpdating = True
End Sub

Private Sub Workbook_BeforeClose(Cancel As Boolean)
    w.Item(2).Saved = True 'this will suppress the safe prompt for the data file only
End Sub

This is somewhat derivative of the answer posted by Ashok.

By doing it this way though you will not get prompted to save changes back to the Excel file your reading from. This is great if the Excel file your reading from is intended as a data source for validation. For example if the workbook contains product names and price data it can be hidden and you can show an Excel file that represents an invoice with drop downs for product that validates from that price list.

You can then store the price list on a shared location on a network somewhere and make it read-only.

Short answer for dummies like me (stolen from Torek):

• origin/master is "where master was over there last time I checked"
• master is "where master is over here based on what I have been doing"

I'm currently simply concatenating the keys into a single string as a workaround. Of course, this will not work on non-string keys. Would love to know the answer as well.

For what it is worth, an additional consideration when using .NET 4.0 is that if a valid endpoint is not found in your configuration, a default endpoint will be automatically created and used.

The default endpoint will use all default values so if you think you have a valid service configuration with a large value for maxReceivedMessageSize etc., but there is something wrong with the configuration, you would still get the 400 Bad Request since a default endpoint would be created and used.

This is done silently so it is hard to detect. You will see messages to this effect (e.g. 'No Endpoint found for Service, creating Default Endpoint' or similar) if you turn on tracing on the server but there is no other indication (to my knowledge).

The standard Python libraries don't include any tzinfo classes (but see pep 431). I can only guess at the reasons. Personally I think it was a mistake not to include a tzinfo class for UTC, because that one is uncontroversial enough to have a standard implementation.

Edit: Although there's no implementation in the library, there is one given as an example in the tzinfo documentation.

from datetime import timedelta, tzinfo

ZERO = timedelta(0)

# A UTC class.

class UTC(tzinfo):
    """UTC"""

    def utcoffset(self, dt):
        return ZERO

    def tzname(self, dt):
        return "UTC"

    def dst(self, dt):
        return ZERO

utc = UTC()

To use it, to get the current time as an aware datetime object:

from datetime import datetime 

now = datetime.now(utc)

There is datetime.timezone.utc in Python 3.2+:

from datetime import datetime, timezone 

now = datetime.now(timezone.utc)

For me the problem was that there was a div above it (which of course shouldn't have been in the head, but it happens). Firefox didn't mind, but Chrome did.

There is now a way to easily do this in most modern browsers using

document.execCommand('copy');

This will copy currently selected text. You can select a textArea or input field using

document.getElementById('myText').select();

To invisibly copy text you can quickly generate a textArea, modify the text in the box, select it, copy it, and then delete the textArea. In most cases this textArea wont even flash onto the screen.

For security reasons, browsers will only allow you copy if a user takes some kind of action (ie. clicking a button). One way to do this would be to add an onClick event to a html button that calls a method which copies the text.

A full example:

function copier(){_x000D_
  document.getElementById('myText').select();_x000D_
  document.execCommand('copy');_x000D_
}

<button onclick="copier()">Copy</button>_x000D_
<textarea id="myText">Copy me PLEASE!!!</textarea>

Java doesn't use includes the way C does. Instead java uses a concept called the classpath, a list of resources containing java classes. The JVM can access any class on the classpath by name so if you can extend classes and refer to types simply by declaring them. The closes thing to an include statement java has is 'import'. Since classes are broken up into namespaces like foo.bar.Baz, if you're in the qux package and you want to use the Baz class without having to use its full name of foo.bar.Baz, then you need to use an import statement at the beginning of your java file like so: import foo.bar.Baz

It may very well be a mistake on the original author, however the notion that 1 is true and 0 is false is not a universal concept. In shell scripting 0 is returned for success, and any other number for failure. In other languages such as Ruby, only nil and false are considered false, and any other value is considered true, so in Ruby both 1 and 0 would be considered true.

If you are in same network then add the destination server to the MS Server management studio using connect option and then try exporting from source to destination. The most easiest way :)

Do you have a Windows machine or a Linux machine?

Under Windows cron is called 'Scheduled Tasks'. It's located in the Control Panel. You can set several scripts to run at specified times in the control panel. Use the wizard to define the scheduled times. Be sure that PHP is callable in your PATH.

Under Linux you can create a crontab for your current user by typing:

crontab -e [username]

If this command fails, it's likely that cron is not installed. If you use a Debian based system (Debian, Ubuntu), try the following commands first:

sudo apt-get update
sudo apt-get install cron

If the command runs properly, a text editor will appear. Now you can add command lines to the crontab file. To run something every five minutes:

*/5 * * * *  /home/user/test.pl

The syntax is basically this:

.---------------- minute (0 - 59) 
|  .------------- hour (0 - 23)
|  |  .---------- day of month (1 - 31)
|  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ... 
|  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7)  OR sun,mon,tue,wed,thu,fri,sat 
|  |  |  |  |
*  *  *  *  *  command to be executed

Read more about it on the following pages: Wikipedia: crontab

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.
