The function add() returns the old date, but changes the original date :)

startdate = "20.03.2014";
var new_date = moment(startdate, "DD.MM.YYYY");
new_date.add(5, 'days');
alert(new_date);

Its because the AddDays() method returns a new DateTime, that you are not assigning or using anywhere.

Example of use:

DateTime newDate = endDate.AddDays(2);

simply add to your data structure ( mItems ) , and then notify your adapter about dataset change

private void addItem(String item) {
  mItems.add(item);
  mAdapter.notifyDataSetChanged();
}

addItem("New Item");

Running example:

//If you want add the element before the actual content, use before()_x000D_
$(function () {_x000D_
  $('#AddBefore').click(function () {_x000D_
    $('#Content').before('<p>Text before the button</p>');_x000D_
  });_x000D_
});_x000D_
_x000D_
//If you want add the element after the actual content, use after()_x000D_
$(function () {_x000D_
  $('#AddAfter').click(function () {_x000D_
    $('#Content').after('<p>Text after the button</p>');_x000D_
  });_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0/jquery.min.js"></script>_x000D_
_x000D_
<div id="Content">_x000D_
<button id="AddBefore">Add before</button>_x000D_
<button id="AddAfter">Add after</button>_x000D_
</div>

Here's an adaptation of silvertab's solution, with generics retrofitted:

static <T> T[] concat(T[] a, T[] b) {
    final int alen = a.length;
    final int blen = b.length;
    final T[] result = (T[]) java.lang.reflect.Array.
            newInstance(a.getClass().getComponentType(), alen + blen);
    System.arraycopy(a, 0, result, 0, alen);
    System.arraycopy(b, 0, result, alen, blen);
    return result;
}

NOTE: See Joachim's answer for a Java 6 solution. Not only does it eliminate the warning; it's also shorter, more efficient and easier to read!

Setting the $PYTHONPATH environment variable does not seem to affect the Spyder IDE's iPython terminals on a Mac. However, Spyder's application menu contains a "PYTHONPATH manager." Adding my path here solved my problem. The "PYTHONPATH manager" is also persistent across application restarts.

This is specific to a Mac, because setting the PYTHONPATH environment variable on my Windows PC gives the expected behavior (modules are found) without using the PYTHONPATH manager in Spyder.

.onclick should be set to a function instead of a string. Try

elemm.onclick = function() { alert('blah'); };

instead.

The point is that the first line of your codes is not what you expected.

You should use:

val map = scala.collection.mutable.Map[A,B]()

You then have multiple equivalent alternatives to add items:

scala> val map = scala.collection.mutable.Map[String,String]()
map: scala.collection.mutable.Map[String,String] = Map()


scala> map("k1") = "v1"

scala> map
res1: scala.collection.mutable.Map[String,String] = Map((k1,v1))


scala> map += "k2" -> "v2"
res2: map.type = Map((k1,v1), (k2,v2))


scala> map.put("k3", "v3")
res3: Option[String] = None

scala> map
res4: scala.collection.mutable.Map[String,String] = Map((k3,v3), (k1,v1), (k2,v2))

And starting Scala 2.13:

scala> map.addOne("k4" -> "v4")
res5: map.type = HashMap(k1 -> v1, k2 -> v2, k3 -> v3, k4 -> v4)

You will first need to create a custom layout xml which will represent a single item in your list. You will add your two buttons to this layout along with any other items you want to display from your list.

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" > 

<TextView
    android:id="@+id/list_item_string"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_alignParentLeft="true"
    android:paddingLeft="8dp"
    android:textSize="18sp"
    android:textStyle="bold" /> 

<Button
    android:id="@+id/delete_btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_marginRight="5dp"
    android:text="Delete" /> 

<Button
    android:id="@+id/add_btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toLeftOf="@id/delete_btn"
    android:layout_centerVertical="true"
    android:layout_marginRight="10dp"
    android:text="Add" />

</RelativeLayout>

Next you will need to create a Custom ArrayAdapter Class which you will use to inflate your xml layout, as well as handle your buttons and on click events.

public class MyCustomAdapter extends BaseAdapter implements ListAdapter { 
private ArrayList<String> list = new ArrayList<String>(); 
private Context context; 



public MyCustomAdapter(ArrayList<String> list, Context context) { 
    this.list = list; 
    this.context = context; 
} 

@Override
public int getCount() { 
    return list.size(); 
} 

@Override
public Object getItem(int pos) { 
    return list.get(pos); 
} 

@Override
public long getItemId(int pos) { 
    return list.get(pos).getId();
    //just return 0 if your list items do not have an Id variable.
} 

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    View view = convertView;
    if (view == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
        view = inflater.inflate(R.layout.my_custom_list_layout, null);
    } 

    //Handle TextView and display string from your list
    TextView listItemText = (TextView)view.findViewById(R.id.list_item_string); 
    listItemText.setText(list.get(position)); 

    //Handle buttons and add onClickListeners
    Button deleteBtn = (Button)view.findViewById(R.id.delete_btn);
    Button addBtn = (Button)view.findViewById(R.id.add_btn);

    deleteBtn.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v) { 
            //do something
            list.remove(position); //or some other task
            notifyDataSetChanged();
        }
    });
    addBtn.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v) { 
            //do something
            notifyDataSetChanged();
        }
    });

    return view; 
} 
}

Finally, in your activity you can instantiate your custom ArrayAdapter class and set it to your listview.

public class MyActivity extends Activity { 

@Override
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_my_activity); 

    //generate list
    ArrayList<String> list = new ArrayList<String>();
    list.add("item1");
    list.add("item2");

    //instantiate custom adapter
    MyCustomAdapter adapter = new MyCustomAdapter(list, this);

    //handle listview and assign adapter
    ListView lView = (ListView)findViewById(R.id.my_listview);
    lView.setAdapter(adapter);
}

Hope this helps!

I'd say:

 <a href="#"id="buttonOne">
            <div id="linkedinB">
                <img src="img/linkedinB.png" width="40" height="40">
            </div>
      </div> 

However, it will still be a link. If you want to change your link into a button, you should rename the #buttonone to #buttonone a { your css here }.

Just append() the text nodes:

$('#replyBox').append(quote); 

http://jsfiddle.net/nQErc/

fooList = [1,3,348,2]
fooList.append(3)
fooList.append(2734)
print(fooList) # [1,3,348,2,3,2734]

problem in %time:~0,2% can't set to 24 hrs format, ended with space(1-9), instead of 0(1-9)

go around with:

set HR=%time:~0,2%

set HR=%Hr: =0% (replace space with 0 if any <has a space in between : =0>)

then replace %time:~0,2% with %HR%

good luck

var jsonIssues = []; // new Array
jsonIssues.push( { ID:1, "Name":"whatever" } );
// "push" some more here

When checking for a column in another database, you can simply include the database name:

IF NOT EXISTS (
  SELECT * 
  FROM   DatabaseName.sys.columns 
  WHERE  object_id = OBJECT_ID(N'[DatabaseName].[dbo].[TableName]') 
         AND name = 'ColumnName'
)

1. git add adds your modified files to the queue to be committed later. Files are not committed

2. git commit commits the files that have been added and creates a new revision with a log... If you do not add any files, git will not commit anything. You can combine both actions with git commit -a

3. git push pushes your changes to the remote repository.

This figure from this git cheat sheet gives a good idea of the work flow

git add isn't on the figure because the suggested way to commit is the combined git commit -a, but you can mentally add a git add to the change block to understand the flow.

Lastly, the reason why push is a separate command is because of git's philosophy. git is a distributed versioning system, and your local working directory is your repository! All changes you commit are instantly reflected and recorded. push is only used to update the remote repo (which you might share with others) when you're done with whatever it is that you're working on. This is a neat way to work and save changes locally (without network overhead) and update it only when you want to, instead of at every commit. This indirectly results in easier commits/branching etc (why not, right? what does it cost you?) which leads to more save points, without messing with the repository.

The best and easiest way to clear a JLIST is:

myJlist.setListData(new String[0]);

Based on your comment it looks like your'e only adding the new column if: mysql_query("SELECT * FROM assessment"); returns false. That's probably not what you wanted. Try removing the '!' on front of $sql in the first 'if' statement. So your code will look like:

$sql=mysql_query("SELECT * FROM assessment");
if ($sql) {
 mysql_query("ALTER TABLE assessment ADD q6 INT(1) NOT NULL AFTER q5");
 echo 'Q6 created'; 
}else...

You need to use the new operator when creating the object

Contacts.add(new Data(name, address, contact)); // Creating a new object and adding it to list - single step

or else

Data objt = new Data(name, address, contact); // Creating a new object
Contacts.add(objt); // Adding it to the list

and your constructor shouldn't contain void. Else it becomes a method in your class.

public Data(String n, String a, String c) { // Constructor has the same name as the class and no return type as such

Import datetime and timedelta:

>>> from datetime import datetime, timedelta
>>> str(datetime.now() + timedelta(hours=9))[11:19]
'01:41:44'

But the better way is:

>>> (datetime.now() + timedelta(hours=9)).strftime('%H:%M:%S')
'01:42:05'

You can refer strptime and strftime behavior to better understand how python processes dates and time field

May be this helps

List<String> l = Arrays.asList("+","-");

This was in response to your other question, that looks like it's been deleted....the point still stands.

Looks like a classic Unicode to ASCII issue. The trick would be to find where it's happening.

.NET works fine with Unicode, assuming it's told it's Unicode to begin with (or left at the default).

My guess is that your receiving app can't handle it. So, I'd probably use the ASCIIEncoder with an EncoderReplacementFallback with String.Empty:

using System.Text;

string inputString = GetInput();
var encoder = ASCIIEncoding.GetEncoder();
encoder.Fallback = new EncoderReplacementFallback(string.Empty);

byte[] bAsciiString = encoder.GetBytes(inputString);

// Do something with bytes...
// can write to a file as is
File.WriteAllBytes(FILE_NAME, bAsciiString);
// or turn back into a "clean" string
string cleanString = ASCIIEncoding.GetString(bAsciiString); 
// since the offending bytes have been removed, can use default encoding as well
Assert.AreEqual(cleanString, Default.GetString(bAsciiString));

Of course, in the old days, we'd just loop though and remove any chars greater than 127...well, those of us in the US at least. ;)

The issue stems from your Angular code:

When withCredentials is set to true, it is trying to send credentials or cookies along with the request. As that means another origin is potentially trying to do authenticated requests, the wildcard ("*") is not permitted as the "Access-Control-Allow-Origin" header.

You would have to explicitly respond with the origin that made the request in the "Access-Control-Allow-Origin" header to make this work.

I would recommend to explicitly whitelist the origins that you want to allow to make authenticated requests, because simply responding with the origin from the request means that any given website can make authenticated calls to your backend if the user happens to have a valid session.

I explain this stuff in this article I wrote a while back.

So you can either set withCredentials to false or implement an origin whitelist and respond to CORS requests with a valid origin whenever credentials are involved

Do it like this:

$foo = new stdClass();
$foo->{"bar"} = '1234';

now try:

echo $foo->bar; // should display 1234

First, don't declare variables using var, but

public $my_value;

Then you can access it using

$this->my_value;

and not

$this->$my_value;

Though an old question, I would like to add that currently mock library (backport of unittest.mock) supports assert_not_called method.

Just upgrade yours;

pip install mock --upgrade

If you want to skip running and compiling tests:

mvn -Dmaven.test.skip=true install

If you want to compile but not run tests:

mvn install -DskipTests

I'll give a slightly advanced answer. In Python, functions are first-class objects. This means they can be "dynamically created, destroyed, passed to a function, returned as a value, and have all the rights as other variables in the programming language have."

Calling a function/class instance in Python means invoking the __call__ method of that object. For old-style classes, class instances are also callable but only if the object which creates them has a __call__ method. The same applies for new-style classes, except there is no notion of "instance" with new-style classes. Rather they are "types" and "objects".

As quoted from the Python 2 Data Model page, for function objects, class instances(old style classes), and class objects(new-style classes), "x(arg1, arg2, ...) is a shorthand for x.__call__(arg1, arg2, ...)".

Thus whenever you define a function with the shorthand def funcname(parameters): you are really just creating an object with a method __call__ and the shorthand for __call__ is to just name the instance and follow it with parentheses containing the arguments to the call. Because functions are first class objects in Python, they can be created on the fly with dynamic parameters (and thus accept dynamic arguments). This comes into handy with decorator functions/classes which you will read about later.

For now I suggest reading the Official Python Tutorial.

DataSet is collection of DataTables.... you can get the datatable from DataSet as below.

//here ds is dataset
DatTable dt = ds.Table[0]; /// table of dataset

You could also pass the content to the pseudo element with a data attribute and then use jQuery to manipulate that:

In HTML:

<span>foo</span>

In jQuery:

$('span').hover(function(){
    $(this).attr('data-content','bar');
});

In CSS:

span:after {
    content: attr(data-content) ' any other text you may want';
}

If you want to prevent the 'other text' from showing up, you could combine this with seucolega's solution like this:

In HTML:

<span>foo</span>

In jQuery:

$('span').hover(function(){
    $(this).addClass('change').attr('data-content','bar');
});

In CSS:

span.change:after {
    content: attr(data-content) ' any other text you may want';
}

A little late to the game here, but another option is:

public class NerdDinners : DbContext
{
    public NerdDinners(string connString)
    {
        this.Database.Connection.ConnectionString = connString;
    }
    public DbSet<Dinner> Dinners { get; set; }
}

When I was completely desperate, I did the following, that allowed me to find official zipalign.exe. The short answer is to use the link from official (but not public :-) part of of the site:

https://dl.google.com/android/repository/build-tools_r28-rc1-windows.zip

If you use this recepy after 2018, you probably need the full explanation:

1. Open Android Studio and go

   Android Studio->Tools->Android->SDK Manager->Android SDK->SDK update site
   

2. Write in text editor link and open it in the browser. In my case the first link worked for me:

   https://dl.google.com/android/repository/repository2-1.xml
   

3. Look for the latest package build-tools. In my case, it was build-tools_r28-rc1-windows.zip, but you can find the latest in your time

   Ctrl+F build-tools_
   

4. Substitute in the URL the last part with the found package name like I did:

   https://dl.google.com/android/repository/build-tools_r28-rc1-windows.zip
   

5. Download the package, unzip it and fortunately find official file:

   zipalign.exe
   

If it helps you, your feedback is wellcome.

Define extension: String+Extension.ts

interface String {
  toBoolean(): boolean
}

String.prototype.toBoolean = function (): boolean {
  switch (this) {
    case 'true':
    case '1':
    case 'on':
    case 'yes':
      return true
    default:
      return false
  }
}

And import in any file where you want to use it '@/path/to/String+Extension'

With Java 8, you could use a primitive stream:

if (IntStream.of(12, 16, 19).anyMatch(i -> i == x))

but this may have a slight overhead (or not), depending on the number of comparisons.

Any user whose login shell setting in /etc/passwd is an interactive shell can login. I don't think there's a totally reliable way to tell if a program is an interactive shell; checking whether it's in /etc/shells is probably as good as you can get.

Other users can also login, but the program they run should not allow them to get much access to the system. And users that aren't allowed to login at all should have /etc/false as their shell -- this will just log them out immediately.

If you need to create a user_id then it would be a reasonable assumption that you are referencing a user table. In which case the migration shall be:

rails generate migration AddUserRefToProducts user:references

This command will generate the following migration:

class AddUserRefToProducts < ActiveRecord::Migration
  def change
    add_reference :user, :product, index: true
  end
end

After running rake db:migrate both a user_id column and an index will be added to the products table.

In case you just need to add an index to an existing column, e.g. name of a user table, the following technique may be helpful:

rails generate migration AddIndexToUsers name:string:index will generate the following migration:

class AddIndexToUsers < ActiveRecord::Migration
  def change
    add_column :users, :name, :string
    add_index :users, :name
  end
end

Delete add_column line and run the migration.

In the case described you could have issued rails generate migration AddIndexIdToTable index_id:integer:index command and then delete add_column line from the generated migration. But I'd rather recommended to undo the initial migration and add reference instead:

rails generate migration RemoveUserIdFromProducts user_id:integer
rails generate migration AddUserRefToProducts user:references

I was designing a GUI in SceneBuilder, trying to make the main container adapt to whatever the window size is. It should always be 100% wide.

This is where you can set these values in SceneBuilder:

Toggling the dotted/red lines will actually just add/remove the attributes that Korki posted in his solution (AnchorPane.topAnchor etc.).

The remotePickupDir would be the folder you want to go to on the ftp server. As far as "is this script correct", well, does it work? If it works then it's correct. If it does not work, then tell us what error message or unexpected behaviour you're getting and we'll be better able to help you.

One thing which seems like no one else mentioned: let's say you have a vertical LinearLayout, so in order for the weights in layout/element/view inside it to work 100% properly - all of them must have layout_height property (which must exist in your xml file) set to 0dp. Seems like any other value would mess things up in some cases.

For those who rooted the Android device with Magisk, you can install adb_root from https://github.com/evdenis/adb_root. Then adb root can run smoothly.

You need to tell it that you are using SSL:

props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

In case you miss anything, here is working code:

String  d_email = "[email protected]",
            d_uname = "Name",
            d_password = "urpassword",
            d_host = "smtp.gmail.com",
            d_port  = "465",
            m_to = "[email protected]",
            m_subject = "Indoors Readable File: " + params[0].getName(),
            m_text = "This message is from Indoor Positioning App. Required file(s) are attached.";
    Properties props = new Properties();
    props.put("mail.smtp.user", d_email);
    props.put("mail.smtp.host", d_host);
    props.put("mail.smtp.port", d_port);
    props.put("mail.smtp.starttls.enable","true");
    props.put("mail.smtp.debug", "true");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.socketFactory.port", d_port);
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.socketFactory.fallback", "false");

    SMTPAuthenticator auth = new SMTPAuthenticator();
    Session session = Session.getInstance(props, auth);
    session.setDebug(true);

    MimeMessage msg = new MimeMessage(session);
    try {
        msg.setSubject(m_subject);
        msg.setFrom(new InternetAddress(d_email));
        msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));

Transport transport = session.getTransport("smtps");
            transport.connect(d_host, Integer.valueOf(d_port), d_uname, d_password);
            transport.sendMessage(msg, msg.getAllRecipients());
            transport.close();

        } catch (AddressException e) {
            e.printStackTrace();
            return false;
        } catch (MessagingException e) {
            e.printStackTrace();
            return false;
        }

Git User Manual

use the syntax .ToList() to convert object read from db to list to avoid being re-read again.Hope this would work for it. Thanks.

The 64base method works for large images as well, I use that method to embed all the images into my website, and it works every time. I've done with files up to 2Mb size, jpg and png.

You can always add it exactly for your application

angular.isUndefinedOrNull = function(val) {
    return angular.isUndefined(val) || val === null 
}

OK, the big difference is start from where they are coming from, so constructor is the constructor of your class in JavaScript, on the other side, getInitialState is part of the lifecycle of React.

constructor is where your class get initialised...

Constructor

The constructor method is a special method for creating and initializing an object created with a class. There can only be one special method with the name "constructor" in a class. A SyntaxError will be thrown if the class contains more than one occurrence of a constructor method.

A constructor can use the super keyword to call the constructor of a parent class.

In the React v16 document, they didn't mentioned any preference, but you need to getInitialState if you using createReactClass()...

Setting the Initial State

In ES6 classes, you can define the initial state by assigning this.state in the constructor:

class Counter extends React.Component {
  constructor(props) {
    super(props);
    this.state = {count: props.initialCount};
  }
  // ...
}

With createReactClass(), you have to provide a separate getInitialState method that returns the initial state:

var Counter = createReactClass({
  getInitialState: function() {
    return {count: this.props.initialCount};
  },
  // ...
});

Visit here for more information.

Also created the image below to show few lifecycles of React Compoenents:

You use the CoreLocation framework to access location information about your user. You will need to instantiate a CLLocationManager object and call the asynchronous startUpdatingLocation message. You will get callbacks with the user's location via the CLLocationManagerDelegate that you supply.

In my case, this was happening because the android/gradlew file did not have execute permission. Once granted, this worked fine

Try adding this class

class="pager"

<p class="pager" style="line-height: 70px;">
    <button type="submit" class="btn">Confirm</button>
</p>

I tried mine within a <div class=pager><button etc etc></div> which worked well

See http://getbootstrap.com/components/ look under Pagination -> Pager

This looks like the correct bootstrap class to center this, text-align: center; is meant for text not images and blocks etc.

It's not generally correct that you can "remove an item from a database" with both methods. To be precise it is like so:

• ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

• EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

  • If the relationship is optional, i.e. the foreign key that refers from the child to the parent in the database allows NULL values, this foreign will be set to null and if you call SaveChanges this NULL value for the childEntity will be written to the database (i.e. the relationship between the two is removed). This happens with a SQL UPDATE statement. No DELETE statement occurs.

  • If the relationship is required (the FK doesn't allow NULL values) and the relationship is not identifying (which means that the foreign key is not part of the child's (composite) primary key) you have to either add the child to another parent or you have to explicitly delete the child (with DeleteObject then). If you don't do any of these a referential constraint is violated and EF will throw an exception when you call SaveChanges - the infamous "The relationship could not be changed because one or more of the foreign-key properties is non-nullable" exception or similar.

  • If the relationship is identifying (it's necessarily required then because any part of the primary key cannot be NULL) EF will mark the childEntity as Deleted as well. If you call SaveChanges a SQL DELETE statement will be sent to the database. If no other referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

I am actually a bit confused about the Remarks section on the MSDN page you have linked because it says: "If the relationship has a referential integrity constraint, calling the Remove method on a dependent object marks both the relationship and the dependent object for deletion.". This seems unprecise or even wrong to me because all three cases above have a "referential integrity constraint" but only in the last case the child is in fact deleted. (Unless they mean with "dependent object" an object that participates in an identifying relationship which would be an unusual terminology though.)

Working code as below:

var array = [2, 42, 82, 122, 162, 202, 242, 282, 322, 362];_x000D_
_x000D_
function closest(array, num) {_x000D_
  var i = 0;_x000D_
  var minDiff = 1000;_x000D_
  var ans;_x000D_
  for (i in array) {_x000D_
    var m = Math.abs(num - array[i]);_x000D_
    if (m < minDiff) {_x000D_
      minDiff = m;_x000D_
      ans = array[i];_x000D_
    }_x000D_
  }_x000D_
  return ans;_x000D_
}_x000D_
console.log(closest(array, 88));

Here is one case that caught me out, using a global as a default value of a parameter.

globVar = None    # initialize value of global variable

def func(param = globVar):   # use globVar as default value for param
    print 'param =', param, 'globVar =', globVar  # display values

def test():
    global globVar
    globVar = 42  # change value of global
    func()

test()
=========
output: param = None, globVar = 42

I had expected param to have a value of 42. Surprise. Python 2.7 evaluated the value of globVar when it first parsed the function func. Changing the value of globVar did not affect the default value assigned to param. Delaying the evaluation, as in the following, worked as I needed it to.

def func(param = eval('globVar')):       # this seems to work
    print 'param =', param, 'globVar =', globVar  # display values

Or, if you want to be safe,

def func(param = None)):
    if param == None:
        param = globVar
    print 'param =', param, 'globVar =', globVar  # display values

Another different answer to an old question. However, I found a implementation made specifically for bootstrap which might prove useful here. Hope this helps anybody who is looking...

Bootstrap-select

Yes. You need to close the resultset, the statement and the connection. If the connection has come from a pool, closing it actually sends it back to the pool for reuse.

You typically have to do this in a finally{} block, such that if an exception is thrown, you still get the chance to close this.

Many frameworks will look after this resource allocation/deallocation issue for you. e.g. Spring's JdbcTemplate. Apache DbUtils has methods to look after closing the resultset/statement/connection whether null or not (and catching exceptions upon closing), which may also help.

I tried the suggested solutions by everyone, but I had to improvise code myself to actually make it work. Following is my improvised code:

import signal
import sys
import time

def signal_handler(signal, frame):
    print('You pressed Ctrl+C!')
    print(signal) # Value is 2 for CTRL + C
    print(frame) # Where your execution of program is at moment - the Line Number
    sys.exit(0)

#Assign Handler Function
signal.signal(signal.SIGINT, signal_handler)

# Simple Time Loop of 5 Seconds
secondsCount = 5
print('Press Ctrl+C in next '+str(secondsCount))
timeLoopRun = True 
while timeLoopRun:  
    time.sleep(1)
    if secondsCount < 1:
        timeLoopRun = False
    print('Closing in '+ str(secondsCount)+ ' seconds')
    secondsCount = secondsCount - 1

The browser is trying to convert chucknorris into hex colour code, because it’s not a valid value.

1. In chucknorris, everything except c is not a valid hex value.
2. So it gets converted to c00c00000000.
3. Which becomes #c00000, a shade of red.

This seems to be an issue primarily with Internet Explorer and Opera (12) as both Chrome (31) and Firefox (26) just ignore this.

P.S. The numbers in brackets are the browser versions I tested on.

On a lighter note

Chuck Norris doesn’t conform to web standards. Web standards conform to him. #BADA55

Just put this in the first line of your script :

#!/usr/bin/env python

Make the file executable with

chmod +x myfile.py

Execute with

./myfile.py

I know this is an old question, but since php7.0 you can use the null coalescing operator (another resource).

It similar to the ternary operator, but will behave like isset on the lefthand operand instead of just using its boolean value.

$slide = $_GET["id"] ?? 'fallback';

So if $_GET["id"] is set, it returns the value. If not, it returns the fallback. I found this very helpful for $_POST, $_GET, or any passed parameters, etc

$slide = $_GET["id"] ?? '';

if (trim($slide) == 'link1') ...

Probably already too late to answer but since you have already parse the dates while loading the data, you can just do this to get the day

df['date'] = pd.DatetimeIndex(df['date']).year

#Case 1: download file with small size.

• You can use url with format https://drive.google.com/uc?export=download&id=FILE_ID and then inputstream of file can be obtained directly.

#Case 2: download file with large size.

• You stuck a wall of a virus scan alert page returned. By parsing html dom element, I tried to get link with confirm code under button "Download anyway" but it didn't work. Its may required cookie or session info. enter image description here

SOLUTION:

• Finally I found solution for two above cases. Just need to put httpConnection.setDoOutput(true) in connection step to get a Json.

  )]}' { "disposition":"SCAN_CLEAN", "downloadUrl":"http:www...", "fileName":"exam_list_json.txt", "scanResult":"OK", "sizeBytes":2392}

Then, you can use any Json parser to read downloadUrl, fileName and sizeBytes.

• You can refer follow snippet, hope it help.

The answers are perfect for adjust map boundaries for markers but if you like to expand Google Maps boundaries for shapes like polygons and circles, you can use following codes:

For Circles

bounds.union(circle.getBounds());

For Polygons

polygon.getPaths().forEach(function(path, index)
{
    var points = path.getArray();
    for(var p in points) bounds.extend(points[p]);
});

For Rectangles

bounds.union(overlay.getBounds());

For Polylines

var path = polyline.getPath();

var slat, blat = path.getAt(0).lat();
var slng, blng = path.getAt(0).lng();

for(var i = 1; i < path.getLength(); i++)
{
    var e = path.getAt(i);
    slat = ((slat < e.lat()) ? slat : e.lat());
    blat = ((blat > e.lat()) ? blat : e.lat());
    slng = ((slng < e.lng()) ? slng : e.lng());
    blng = ((blng > e.lng()) ? blng : e.lng());
}

bounds.extend(new google.maps.LatLng(slat, slng));
bounds.extend(new google.maps.LatLng(blat, blng));

you can use getBackStackEntryAt(). In order to know how many entry the activity holds in the backstack you can use getBackStackEntryCount()

int lastFragmentCount = getBackStackEntryCount() - 1;

Have a look at Runtime.exec() Javadoc

Process p = Runtime.getRuntime().exec("ssh myhost");
PrintStream out = new PrintStream(p.getOutputStream());
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));

out.println("ls -l /home/me");
while (in.ready()) {
  String s = in.readLine();
  System.out.println(s);
}
out.println("exit");

p.waitFor();

ECUs (EC2 Computer Units) are a rough measure of processor performance that was introduced by Amazon to let you compare their EC2 instances ("servers").

CPU performance is of course a multi-dimensional measure, so putting a single number on it (like "5 ECU") can only be a rough approximation. If you want to know more exactly how well a processor performs for a task you have in mind, you should choose a benchmark that is similar to your task.

In early 2014, there was a nice benchmarking site comparing cloud hosting offers by tens of different benchmarks, over at CloudHarmony benchmarks. However, this seems gone now (and archive.org can't help as it was a web application). Only an introductory blog post is still available.

Also useful: ec2instances.info, which at least aggregates the ECU information of different EC2 instances for comparison. (Add column "Compute Units (ECU)" to make it work.)

I have used a script but to make a join, maybe I can help you

string Email = String.Join(", ", Emails.Where(i => i.Email != "").Select(i => i.Email).Distinct());

First, I downloaded a test TIFF image from this page called a_image.tif. Then I opened with PIL like this:

>>> from PIL import Image
>>> im = Image.open('a_image.tif')
>>> im.show()

This showed the rainbow image. To convert to a numpy array, it's as simple as:

>>> import numpy
>>> imarray = numpy.array(im)

We can see that the size of the image and the shape of the array match up:

>>> imarray.shape
(44, 330)
>>> im.size
(330, 44)

And the array contains uint8 values:

>>> imarray
array([[  0,   1,   2, ..., 244, 245, 246],
       [  0,   1,   2, ..., 244, 245, 246],
       [  0,   1,   2, ..., 244, 245, 246],
       ..., 
       [  0,   1,   2, ..., 244, 245, 246],
       [  0,   1,   2, ..., 244, 245, 246],
       [  0,   1,   2, ..., 244, 245, 246]], dtype=uint8)

Once you're done modifying the array, you can turn it back into a PIL image like this:

>>> Image.fromarray(imarray)
<Image.Image image mode=L size=330x44 at 0x2786518>

Your code was a bit mixed up. Here is a clean version:

<script type="text/javascript">
    $(document).ready(function() {
        $("#add").click(function() {
            $.post("SetAndGet.php", {
                know: $("#know").val()
            }, function(data) {
                $("#know_list").html(data);
            });
        });

        function countChar(val) {
            var len = val.value.length;
            if (len >= 500) {
                val.value = val.value.substring(0, 500);
            } else {
                $('#charNum').text(500 - len);
            }
        }
    });
</script>

Here is a working solution in windows 10 that does not include any third-party components. It works by wrapping the PowerShell script into VBScript.

Step 1: we need to change some windows features to allow VBScript to run PowerShell and to open .ps1 files with PowerShell by default.

-go to run and type "regedit". Click on ok and then allow it to run.

-paste this path "HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell" and press enter.

-now open the entry on the right and change the value to 0.

-open PowerShell as an administrator and type "Set-ExecutionPolicy -ExecutionPolicy RemoteSigned", press enter and confirm the change with "y" and then enter.

Step 2: Now we can start wrapping our script.

-save your Powershell script as a .ps1 file.

-create a new text document and paste this script.

Dim objShell,objFSO,objFile

Set objShell=CreateObject("WScript.Shell")
Set objFSO=CreateObject("Scripting.FileSystemObject")

'enter the path for your PowerShell Script
 strPath="c:\your script path\script.ps1"

'verify file exists
 If objFSO.FileExists(strPath) Then
   'return short path name
   set objFile=objFSO.GetFile(strPath)
   strCMD="powershell -nologo -command " & Chr(34) & "&{" &_
    objFile.ShortPath & "}" & Chr(34)
   'Uncomment next line for debugging
   'WScript.Echo strCMD

  'use 0 to hide window
   objShell.Run strCMD,0

Else

  'Display error message
   WScript.Echo "Failed to find " & strPath
   WScript.Quit

End If

-now change the file path to the location of your .ps1 script and save the text document.

-Now right-click on the file and go to rename. Then change the filename extension to .vbs and press enter and then click ok.

DONE! If you now open the .vbs you should see no console window while your script is running in the background.

make sure to upvote if this worked for you!

As an option to kasdega's code above, instead of appending the tab to the current value, you can instead insert characters at the current cursor point. This has the benefit of:

• allows you to insert 4 spaces as an alternative to tab
• undo and redo will work with the inserted characters (it won't with the OP)

so replace

    // set textarea value to: text before caret + tab + text after caret
    $(this).val($(this).val().substring(0, start)
                + "\t"
                + $(this).val().substring(end));

with

    // set textarea value to: text before caret + tab + text after caret
    document.execCommand("insertText", false, '    ');

To test without copy elision and see you copy/move constructors/operators in action add "-fno-elide-constructors".

Even with no optimizations (-O0 ), GCC and Clang will still do copy elision, which has the effect of skipping copy/move constructors in some cases. See this question for the details about copy elision.

However, in Clang 3.4 it does trigger a bug (an invalid temporary object without calling constructor), which is fixed in 3.5.

If you were originally looking for the answer to this question (int value in sorted (Ascending) int array), then you can use the following code that performs a binary search (fastest result):

static inline bool exists(int ints[], int size, int k) // array, array's size, searched value
{
    if (size <= 0)      // check that array size is not null or negative
         return false;
    // sort(ints, ints + size); // uncomment this line if array wasn't previously sorted
    return (std::binary_search(ints, ints + size, k));
}

edit: Also works for unsorted int array if uncommenting sort.

No, TRUNCATE is all or nothing. You can do a DELETE FROM <table> WHERE <conditions> but this loses the speed advantages of TRUNCATE.

There could be a simpler solution, and more correct: The perimeter of earth is 40,000Km at the equator, about 37,000 on Greenwich (or any longitude) cycle. Thus:

pythagoras = function (lat1, lon1, lat2, lon2) {
   function sqr(x) {return x * x;}
   function cosDeg(x) {return Math.cos(x * Math.PI / 180.0);}

   var earthCyclePerimeter = 40000000.0 * cosDeg((lat1 + lat2) / 2.0);
   var dx = (lon1 - lon2) * earthCyclePerimeter / 360.0;
   var dy = 37000000.0 * (lat1 - lat2) / 360.0;

   return Math.sqrt(sqr(dx) + sqr(dy));
};

I agree that it should be fine-tuned as, I myself said that it's an ellipsoid, so the radius to be multiplied by the cosine varies. But it's a bit more accurate. Compared with Google Maps and it did reduce the error significantly.

To add an extra layer of control I use the HTML5 storage to detect if it is using mobile storage or desktop storage. If the browser does not support storage I have an array of mobile browser names and I compare the user agent with the browsers in the array.

It is pretty simple. Here is the function:

// Used to detect whether the users browser is an mobile browser
function isMobile() {
    ///<summary>Detecting whether the browser is a mobile browser or desktop browser</summary>
    ///<returns>A boolean value indicating whether the browser is a mobile browser or not</returns>

    if (sessionStorage.desktop) // desktop storage 
        return false;
    else if (localStorage.mobile) // mobile storage
        return true;

    // alternative
    var mobile = ['iphone','ipad','android','blackberry','nokia','opera mini','windows mobile','windows phone','iemobile']; 
    for (var i in mobile) if (navigator.userAgent.toLowerCase().indexOf(mobile[i].toLowerCase()) > 0) return true;

    // nothing found.. assume desktop
    return false;
}

Piston is very flexible framework for wirting RESTful APIs for Django applications.

It's worth noting that you must open project folder in Visual Studio Code for the debugger to work. I lost few hours to make it work while having only individual file opened in the editor.

This can happens when one library is loaded into gradle several times. Most often through other connected libraries.

Remove a implementation this library in build.gradle

An other solution (if possible) would be to use TomEE instead of Tomcat, which has a working maven plugin:

<plugin>
    <groupId>org.apache.tomee.maven</groupId>
    <artifactId>tomee-maven-plugin</artifactId>
    <version>7.1.1</version>
</plugin>

Version 7.1.1 wraps a Tomcat 8.5.41

Your code can be fixed as follows:

import numpy as np, cv
vis = np.zeros((384, 836), np.float32)
h,w = vis.shape
vis2 = cv.CreateMat(h, w, cv.CV_32FC3)
vis0 = cv.fromarray(vis)
cv.CvtColor(vis0, vis2, cv.CV_GRAY2BGR)

Short explanation:

1. np.uint32 data type is not supported by OpenCV (it supports uint8, int8, uint16, int16, int32, float32, float64)
2. cv.CvtColor can't handle numpy arrays so both arguments has to be converted to OpenCV type. cv.fromarray do this conversion.
3. Both arguments of cv.CvtColor must have the same depth. So I've changed source type to 32bit float to match the ddestination.

Also I recommend you use newer version of OpenCV python API because it uses numpy arrays as primary data type:

import numpy as np, cv2
vis = np.zeros((384, 836), np.float32)
vis2 = cv2.cvtColor(vis, cv2.COLOR_GRAY2BGR)

The best that I've been able to do is

$(this).closest('.modal').modal('toggle');

This gets the modal holding the DOM object you triggered the event on (guessing you're clicking a button). Gets the closest parent '.modal' and toggles it. Obviously only works because it's inside the modal you clicked.

You can however do this:

$(".modal:visible").modal('toggle');

This gets the modal that is displaying (since you can only have one open at a time), and triggers the 'toggle' This would not work without ":visible"

onCreate(Bundle savedInstanceState) Function in Android:

1. When an Activity first call or launched then onCreate(Bundle savedInstanceState) method is responsible to create the activity.

2. When ever orientation(i.e. from horizontal to vertical or vertical to horizontal) of activity gets changed or when an Activity gets forcefully terminated by any Operating System then savedInstanceState i.e. object of Bundle Class will save the state of an Activity.

3. After Orientation changed then onCreate(Bundle savedInstanceState) will call and recreate the activity and load all data from savedInstanceState.

4. Basically Bundle class is used to stored the data of activity whenever above condition occur in app.

5. onCreate() is not required for apps. But the reason it is used in app is because that method is the best place to put initialization code.

6. You could also put your initialization code in onStart() or onResume() and when you app will load first, it will work same as in onCreate().

git gui provides this functionality under the diff view. Just right click the line(s) you're interested in and you should see a "stage this line to commit" menu item.

Not that I know of, unless you select from INFORMATION_SCHEMA, as others have mentioned.

However, the SHOW command is pretty flexible, E.g.:

Use optparse which comes with the standard library. For example:

#!/usr/bin/env python
import optparse

def main():
  p = optparse.OptionParser()
  p.add_option('--person', '-p', default="world")
  options, arguments = p.parse_args()
  print 'Hello %s' % options.person

if __name__ == '__main__':
  main()

However as of Python 2.7 optparse is deprecated, see: Why use argparse rather than optparse?

Here are a couple of methods I wrote that will always round up or down to any value.

public static Double RoundUpToNearest(Double passednumber, Double roundto)
{
    // 105.5 up to nearest 1 = 106
    // 105.5 up to nearest 10 = 110
    // 105.5 up to nearest 7 = 112
    // 105.5 up to nearest 100 = 200
    // 105.5 up to nearest 0.2 = 105.6
    // 105.5 up to nearest 0.3 = 105.6

    //if no rounto then just pass original number back

A short way to LabelEncoder() multiple columns with a dict():

from sklearn.preprocessing import LabelEncoder
le_dict = {col: LabelEncoder() for col in columns }
for col in columns:
    le_dict[col].fit_transform(df[col])

and you can use this le_dict to labelEncode any other column:

le_dict[col].transform(df_another[col])

<?php
$var = new ArrayIterator();

var_dump(is_array($var), ($var instanceof ArrayIterator));

returns bool(false) or bool(true)

all zeros would probably be the most obvious that it wasn't a real SSN.

Breakpoints and especially conditional breakpoints are your friends.

Also you can write small assert like function which will check values and throw exceptions if needed in debug version of site (some variable is set to true or url has some parameter)

Can do this thru a plug-in like Java applet or Flash, then have the Javascript call a function in the applet or vice versa (OR have the JS call a function in Flash or other plugin ) and return the IP. This might not be the IP used by the browser for getting the page contents. Also if there are images, css, js -> browser could have made multiple connections. I think most browsers only use the first IP they get from the DNS call (that connected successfully, not sure what happens if one node goes down after few resources are got and still to get others - timers/ ajax that add html that refer to other resources).

If java applet would have to be signed, make a connection to the window.location (got from javascript, in case applet is generic and can be used on any page on any server) else just back to home server and use java.net.Address to get IP.

renderItem(item)
  {
    const width = '80%';
    var items = [];

    for(let i = 0; i < item.count; i++){

        items.push( <View style={{ padding: 10, borderBottomColor: "#f2f2f2", borderBottomWidth: 10, flexDirection: 'row' }}>
    <View style={{ width }}>
      <Text style={styles.name}>{item.title}</Text>
      <Text style={{ color: '#818181', paddingVertical: 10 }}>{item.taskDataElements[0].description + " "}</Text>
      <Text style={styles.begin}>BEGIN</Text>
    </View>

    <Text style={{ backgroundColor: '#fcefec', padding: 10, color: 'red', height: 40 }}>{this.msToTime(item.minTatTimestamp) <= 0 ? "NOW" : this.msToTime(item.minTatTimestamp) + "hrs"}</Text>
  </View> )
  }

  return items;
}

render() {
return (this.renderItem(this.props.item)) 
}

I use something like this

>>> import datetime
>>> regex = datetime.datetime.strptime
>>>
>>> # TEST
>>> assert regex('2020-08-03', '%Y-%m-%d')
>>>

>>> assert regex('2020-08', '%Y-%m-%d')
ValueError: time data '2020-08' does not match format '%Y-%m-%d'

>>> assert regex('08/03/20', '%m/%d/%y')
>>>

>>> assert regex('08-03-2020', '%m/%d/%y')
ValueError: time data '08-03-2020' does not match format '%m/%d/%y'

If you get a message from git complaining about the value 'simple' in the configuration, check your git version.

After upgrading Xcode (on a Mac running Mountain Lion), which also upgraded git from 1.7.4.4 to 1.8.3.4, shells started before the upgrade were still running git 1.7.4.4 and complained about the value 'simple' for push.default in the global config.

The solution was to close the shells running the old version of git and use the new version.

No; instances of class File represent a path in a filesystem. Therefore, you can use that function only with a file. But perhaps there is an overload that takes an InputStream instead?

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.

If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.

If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).

In windows it is

java -cp .;/path/junit.jar org.junit.runner.JUnitCore TestClass [test class name without .class extension]

for example: c:\>java -cp .;f:/libraries/junit-4.8.2 org.junit.runner.JUnitCore TestSample1 TestSample2 ... and so on, if one has more than one test classes.

-cp stands for class path and the dot (.) represents the existing classpath while semi colon (;) appends the additional given jar to the classpath , as in above example junit-4.8.2 is now available in classpath to execute JUnitCore class that here we have used to execute our test classes.

Above command line statement helps you to execute junit (version 4+) tests from command prompt(i-e MSDos).

Note: JUnitCore is a facade to execute junit tests, this facade is included in 4+ versions of junit.

You can use

str1.compareTo(str2);

If str1 is lexicographically less than str2, a negative number will be returned, 0 if equal or a positive number if str1 is greater.

E.g.,

"a".compareTo("b"); // returns a negative number, here -1
"a".compareTo("a"); // returns  0
"b".compareTo("a"); // returns a positive number, here 1
"b".compareTo(null); // throws java.lang.NullPointerException

I find that some of these answers are vague and complicated, I find the best way to figure out these things for sure is to just open up the console and test it yourself.

var x;

x == null            // true
x == undefined       // true
x === null           // false
x === undefined      // true

var y = null;

y == null            // true
y == undefined       // true
y === null           // true
y === undefined      // false

typeof x             // 'undefined'
typeof y             // 'object'

var z = {abc: null};

z.abc == null        // true
z.abc == undefined   // true
z.abc === null       // true
z.abc === undefined  // false

z.xyz == null        // true
z.xyz == undefined   // true
z.xyz === null       // false
z.xyz === undefined  // true

null = 1;            // throws error: invalid left hand assignment
undefined = 1;       // works fine: this can cause some problems

So this is definitely one of the more subtle nuances of JavaScript. As you can see, you can override the value of undefined, making it somewhat unreliable compared to null. Using the == operator, you can reliably use null and undefined interchangeably as far as I can tell. However, because of the advantage that null cannot be redefined, I might would use it when using ==.

For example, variable != null will ALWAYS return false if variable is equal to either null or undefined, whereas variable != undefined will return false if variable is equal to either null or undefined UNLESS undefined is reassigned beforehand.

You can reliably use the === operator to differentiate between undefined and null, if you need to make sure that a value is actually undefined (rather than null).

According to the ECMAScript 5 spec:

• Both Null and Undefined are two of the six built in types.

4.3.9 undefined value

primitive value used when a variable has not been assigned a value

4.3.11 null value

primitive value that represents the intentional absence of any object value

In your code result is not changing, its var properties are changing. Refer comments below:

fun copyAddress(address: Address): Address {
    val result = Address() // result is read only
    result.name = address.name // but not their properties.
    result.street = address.street
    // ...
    return result
}

val is same as the final modifier in java. As you should probably know that we can not assign to a final variable again but can change its properties.

IF "%~1"=="" GOTO :Usage

~ will de-quote %1 if %1 itself is quoted.

" " will protect from special characters passed. for example calling the script with &ping

File f = new File(filePathString); 

This will not create a physical file. Will just create an object of the class File. To physically create a file you have to explicitly create it:

f.createNewFile();

So f.exists() can be used to check whether such a file exists or not.

Simple way to iterate over class fields and obtain values from object:

 Class<?> c = obj.getClass();
 Field[] fields = c.getDeclaredFields();
 Map<String, Object> temp = new HashMap<String, Object>();

 for( Field field : fields ){
      try {
           temp.put(field.getName().toString(), field.get(obj));
      } catch (IllegalArgumentException e1) {
      } catch (IllegalAccessException e1) {
      }
 }

If you're talking about ASP.NET MVC then you should have a controller method that returns the following:

return Redirect("http://www.google.com");

Otherwise we need more info on the error you're getting in the redirect. I'd step through to make sure the url isn't empty.

OK this worked for me.

1. Open the solution in Visual Studio 2013
2. Select File | Add to Source Control
3. Select the Microsoft Git Provider

That creates a local GIT repository

3. Surf to GitHub
4. Create a new repository DO NOT SELECT Initialize this repository with a README

That creates an empty repository with no Master branch

1. Once created open the repository and copy the URL (it's on the right of the screen in the current version)
2. Go back to Visual Studio
   • Make sure you have the Microsoft Git Provider selected under Tools/Options/Source Control/Plug-in Selection
3. Open Team Explorer
4. Select Home | Unsynced Commits
5. Enter the GitHub URL into the yellow box (use HTTPS URL, not the default shown SSH one)
6. Click Publish
7. Select Home | Changes
8. Add a Commit comment
9. Select Commit and Push from the drop down

Your solution is now in GitHub

you can retreive data like this :

<script>
var data = CKEDITOR.instances.editor1.getData();
// Your code to save "data", usually through Ajax.
</script>

A very general command prompt how to for java is

javac mainjava.java
java mainjava

You'll very often see people doing

javac *.java
java mainjava

As for the subclass problem that's probably occurring because a path is missing from your class path, the -c flag I believe is used to set that.

At work here we use Dotfuscator from PreEmptive Solutions.

Although it's impossible to protect .NET assemblies 100% Dotfuscator makes it hard enough I think. I comes with a lot of obfuscation techniques;

Cross Assembly Renaming
Renaming Schemes
Renaming Prefix
Enhanced Overload Induction
Incremental Obfuscation
HTML Renaming Report
Control Flow
String Encryption

And it turned out that they're not very expensive for small companies. They have a special pricing for small companies.

(No I'm not working for PreEmptive ;-))

There are freeware alternatives of course;

before you send the email you can press <ESC> f (Escape followed by f) to change the From: Address.

Constraint: This only works if you use mutt in curses mode and do not wan't to script it or if you want to change the address permanent. Then the other solutions are way better!

Try View.INVISIBLE.

select convert(nvarchar(255), 4343)

Should do the trick.

try

pip3 install --user --upgrade pandas

as @rampion mentioned, if you are in clang gcc, the warnings are by name, not number, and you'll need to do:

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wunused-variable"
// ..your code..
#pragma clang diagnostic pop

this info comes from here

Cleanest and fastest way (ES6)

const apps = [
  {id:1, name:'Jon'}, 
  {id:2, name:'Dave'},
  {id:3, name:'Joe'}
]

//remove item with id=2
const itemToBeRemoved = {id:2, name:'Dave'}

apps.splice(apps.findIndex(a => a.id === itemToBeRemoved.id) , 1)

//print result
console.log(apps)

Update: if any chance item doesn't exist in the look up array please use below solution, updated based on MaxZoom's comment

const apps = [
  {id:1, name:'Jon'}, 
  {id:3, name:'Joe'}
]

//remove item with id=2
const itemToBeRemoved = {id:2, name:'Dave'}

const findIndex = apps.findIndex(a => a.id === itemToBeRemoved.id)

findIndex !== -1 && apps.splice(findIndex , 1)

//print result
console.log(apps)

I suffered from this issue too a lot, in my case Downloading missing NuGet was checked (but it is not restoring them) and i can not uninstall & re-install because i modified some of the installed packages ... so:

I just cleared the cached and rebuild and it worked. (Tools-Option-Nuget Package Manager - General)

How to do it 100% through the Sourcetree GUI

(Not everyone likes doing things through the git command line interface)

Once this has been set up, you only need to do steps 7-13 from then on.

Fetch > checkout master branch > reset to their master > Push changes to server

Steps

1. In the menu toolbar at the top of the screen: "Repository" > "Repository settings"

2. "Add"

3. Go back to GitHub and copy the clone URL.

4. Paste the url into the "URL / Path" field then give it a name that makes sense. I called it "master". Do not check the "Default remote" checkbox. You will not be able to push directly to this repository.

5. Press "OK" and you should see it appear in your list of repositories now.

6. Press "OK" again and you should see it appear in your list of "Remotes".

7. Click the "Fetch" button (top left of the Source tree header area)

8. Make sure the "Fetch from all remotes" checkbox is checked and press "ok"

9. Double click on your "master" branch to check it out if it is not checked out already.

10. Find the commit that you want to reset to, if you called the repo "master" you will most likely want to find the commit with the "master/master" tag on it.

11. Right click on the commit > "Reset current branch to this commit".

12. In the dialog, set the "Using mode:" field to "Hard - discard all working copy changes" then press "OK" (make sure to put any changes that you don't want to lose onto a separate branch first).

13. Click the "Push" button (top left of the Source tree header area) to upload the changes to your copy of the repo.

Your Done!

As a newbie in React world, I came across a similar issues where I could not edit the textarea and struggled with binding. It's worth knowing about controlled and uncontrolled elements when it comes to react.

The value of the following uncontrolled textarea cannot be changed because of value

 <textarea type="text" value="some value"
    onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following uncontrolled textarea can be changed because of use of defaultValue or no value attribute

<textarea type="text" defaultValue="sample" 
    onChange={(event) => this.handleOnChange(event)}></textarea>

<textarea type="text" 
   onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following controlled textarea can be changed because of how value is mapped to a state as well as the onChange event listener

<textarea value={this.state.textareaValue} 
onChange={(event) => this.handleOnChange(event)}></textarea>

Here is my solution using different syntax. I prefer the auto-bind than manual binding however, if I were to not use {(event) => this.onXXXX(event)} then that would cause the content of textarea to be not editable OR the event.preventDefault() does not work as expected. Still a lot to learn I suppose.

class Editor extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      textareaValue: ''
    }
  }
  handleOnChange(event) {
    this.setState({
      textareaValue: event.target.value
    })
  }
  handleOnSubmit(event) {
    event.preventDefault();
    this.setState({
      textareaValue: this.state.textareaValue + ' [Saved on ' + (new Date()).toLocaleString() + ']'
    })
  }
  render() {
    return <div>
        <form onSubmit={(event) => this.handleOnSubmit(event)}>
          <textarea rows={10} cols={30} value={this.state.textareaValue} 
            onChange={(event) => this.handleOnChange(event)}></textarea>
          <br/>
          <input type="submit" value="Save"/>
        </form>
      </div>
  }
}
ReactDOM.render(<Editor />, document.getElementById("content"));

The versions of libraries are

"babel-cli": "6.24.1",
"babel-preset-react": "6.24.1"
"React & ReactDOM v15.5.4" 

Here is an overview of the many ways that can be done, for my own reference as well as yours :) The functions return a hash of attribute names and their values.

Vanilla JS:

function getAttributes ( node ) {
    var i,
        attributeNodes = node.attributes,
        length = attributeNodes.length,
        attrs = {};

    for ( i = 0; i < length; i++ ) attrs[attributeNodes[i].name] = attributeNodes[i].value;
    return attrs;
}

Vanilla JS with Array.reduce

Works for browsers supporting ES 5.1 (2011). Requires IE9+, does not work in IE8.

function getAttributes ( node ) {
    var attributeNodeArray = Array.prototype.slice.call( node.attributes );

    return attributeNodeArray.reduce( function ( attrs, attribute ) {
        attrs[attribute.name] = attribute.value;
        return attrs;
    }, {} );
}

jQuery

This function expects a jQuery object, not a DOM element.

function getAttributes ( $node ) {
    var attrs = {};
    $.each( $node[0].attributes, function ( index, attribute ) {
        attrs[attribute.name] = attribute.value;
    } );

    return attrs;
}

Underscore

Also works for lodash.

function getAttributes ( node ) {
    return _.reduce( node.attributes, function ( attrs, attribute ) {
        attrs[attribute.name] = attribute.value;
        return attrs;
    }, {} );
}

lodash

Is even more concise than the Underscore version, but only works for lodash, not for Underscore. Requires IE9+, is buggy in IE8. Kudos to @AlJey for that one.

function getAttributes ( node ) {
    return _.transform( node.attributes, function ( attrs, attribute ) {
        attrs[attribute.name] = attribute.value;
    }, {} );
}

Test page

At JS Bin, there is a live test page covering all these functions. The test includes boolean attributes (hidden) and enumerated attributes (contenteditable="").

I've used Xavier's answer quite a bit. I want to add that restricting the package version to a specified range is easy and useful in the latest versions of NuGet.

For example, if you never want Newtonsoft.Json to be updated past version 3.x.x in your project, change the corresponding package element in your packages.config file to look like this:

<package id="Newtonsoft.Json" version="3.5.8" allowedVersions="[3.0, 4.0)" targetFramework="net40" />

Notice the allowedVersions attribute. This will limit the version of that package to versions between 3.0 (inclusive) and 4.0 (exclusive). Then, when you do an Update-Package on the whole solution, you don't need to worry about that particular package being updated past version 3.x.x.

The documentation for this functionality is here.

I know this is an old post, but just wrote this function and will leave it here is case someone stumbles looking for an answer:

def classMethods(the_class,class_only=False,instance_only=False,exclude_internal=True):

    def acceptMethod(tup):
        #internal function that analyzes the tuples returned by getmembers tup[1] is the 
        #actual member object
        is_method = inspect.ismethod(tup[1])
        if is_method:
            bound_to = tup[1].im_self
            internal = tup[1].im_func.func_name[:2] == '__' and tup[1].im_func.func_name[-2:] == '__'
            if internal and exclude_internal:
                include = False
            else:
                include = (bound_to == the_class and not instance_only) or (bound_to == None and not class_only)
        else:
            include = False
        return include
    #uses filter to return results according to internal function and arguments
    return filter(acceptMethod,inspect.getmembers(the_class))

The right solution is to Specialize std::less for your class/Struct.

• Basically maps in cpp are implemented as Binary Search Trees.

1. BSTs compare elements of nodes to determine the organization of the tree.
2. Nodes who's element compares less than that of the parent node are placed on the left of the parent and nodes whose elements compare greater than the parent nodes element are placed on the right. i.e.

For each node, node.left.key < node.key < node.right.key

Every node in the BST contains Elements and in case of maps its KEY and a value, And keys are supposed to be ordered. More About Map implementation : The Map data Type.

In case of cpp maps , keys are the elements of the nodes and values does not take part in the organization of the tree its just a supplementary data .

So It means keys should be compatible with std::less or operator< so that they can be organized. Please check map parameters.

Else if you are using user defined data type as keys then need to give meaning full comparison semantics for that data type.

Solution : Specialize std::less:

The third parameter in map template is optional and it is std::less which will delegate to operator< ,

So create a new std::less for your user defined data type. Now this new std::less will be picked by std::map by default.

namespace std
{
    template<> struct  less<MyClass>
    {
        bool operator() (const MyClass& lhs, const MyClass& rhs) const
        {
            return lhs.anyMemen < rhs.age;
        }
    };

}

Note: You need to create specialized std::less for every user defined data type(if you want to use that data type as key for cpp maps).

Bad Solution: Overloading operator< for your user defined data type. This solution will also work but its very bad as operator < will be overloaded universally for your data type/class. which is undesirable in client scenarios.

Everything seems to be perfect in your code except the fact that handleClick() isn't working because this function lacks a parameter in its function call invocation(but the function definition within has an argument which makes a function mismatch to occur).

The following is a sample working code for calculating all semester's total marks and corresponding grade. It demonstrates the use of a JavaScript function(call) within a html file and also solves the problem you are facing.

You're thinking too DOM, it's a hard as hell habit to break. Vue recommends you approach it data first.

It's kind of hard to tell in your exact situation but I'd probably use a v-for and make an array of finds to push to as I need more.

Here's how I'd set up my instance:

new Vue({
  el: '#app',
  data: {
    finds: []
  },
  methods: {
    addFind: function () {
      this.finds.push({ value: '' });
    }
  }
});

And here's how I'd set up my template:

<div id="app">
  <h1>Finds</h1>
  <div v-for="(find, index) in finds">
    <input v-model="find.value" :key="index">
  </div>
  <button @click="addFind">
    New Find
  </button>
</div>

Although, I'd try to use something besides an index for the key.

Here's a demo of the above: https://jsfiddle.net/crswll/24txy506/9/

If you want to make Django version comparison, you could use django-nine (pip install django-nine). For example, if Django version installed in your environment is 1.7.4, then the following would be true.

from nine import versions

versions.DJANGO_1_7 # True
versions.DJANGO_LTE_1_7 # True
versions.DJANGO_GTE_1_7 # True
versions.DJANGO_GTE_1_8 # False
versions.DJANGO_GTE_1_4 # True
versions.DJANGO_LTE_1_6 # False

Try this

const returnedTarget = Object.assign(target, source);

and pass empty array to target

in case complex objects this way works for me

$.extend(true, [], originalArray) in case of array

$.extend(true, {}, originalObject) in case of object

You can do it using a jquery,

Use this code to link the button...

$(document).ready(function() {
    $("#button_id").click(function() {
        window.print();
        return false;
    });
});

First off, you have to specify you wish to use Document Literal style:

$client = new SoapClient(NULL, array(
    'location' => 'https://example.com/path/to/service',
    'uri' => 'http://example.com/wsdl',
    'trace' => 1,
    'use' => SOAP_LITERAL)
);

Then, you need to transform your data into a SoapVar; I've written a simple transform function:

function soapify(array $data)
{
        foreach ($data as &$value) {
                if (is_array($value)) {
                        $value = soapify($value);
                }
        }

        return new SoapVar($data, SOAP_ENC_OBJECT);
}

Then, you apply this transform function onto your data:

$data = soapify(array(
    'Acquirer' => array(
        'Id' => 'MyId',
        'UserId' => 'MyUserId',
        'Password' => 'MyPassword',
    ),
));

Finally, you call the service passing the Data parameter:

$method = 'Echo';

$result = $client->$method(new SoapParam($data, 'Data'));

Another common cause of this error on the Mac is Apple's quarantine flag.

ls the directory containing the resource(s) in question. If you see the extended attribute indicator, i.e., the little @ symbol at the end of the permissions block (e.g. -rw-r--r--@ ) then the file could be quarantined.

Try ls -la@e and look for com.apple.quarantine

The following command will remove the quarantine:

xattr -d com.apple.quarantine /path/to/file

First of all, it's not very tidy to mix pylab and pyplot code. What's more, pyplot style is preferred over using pylab.

Here is a slightly cleaned up code, using only pyplot functions:

from matplotlib import pyplot

a = [ pow(10,i) for i in range(10) ]

pyplot.subplot(2,1,1)
pyplot.plot(a, color='blue', lw=2)
pyplot.yscale('log')
pyplot.show()

The relevant function is pyplot.yscale(). If you use the object-oriented version, replace it by the method Axes.set_yscale(). Remember that you can also change the scale of X axis, using pyplot.xscale() (or Axes.set_xscale()).

Check my question What is the difference between ‘log’ and ‘symlog’? to see a few examples of the graph scales that matplotlib offers.

While using the wait and notify or notifyAll methods in Java the following things must be remembered:

1. Use notifyAll instead of notify if you expect that more than one thread will be waiting for a lock.
2. The wait and notify methods must be called in a synchronized context. See the link for a more detailed explanation.
3. Always call the wait() method in a loop because if multiple threads are waiting for a lock and one of them got the lock and reset the condition, then the other threads need to check the condition after they wake up to see whether they need to wait again or can start processing.
4. Use the same object for calling wait() and notify() method; every object has its own lock so calling wait() on object A and notify() on object B will not make any sense.

Update: MySQL 8.0 is finally getting the feature of common table expressions, including recursive CTEs.

Here's a blog announcing it: http://mysqlserverteam.com/mysql-8-0-labs-recursive-common-table-expressions-in-mysql-ctes/

Below is my earlier answer, which I originally wrote in 2008.

MySQL 5.x does not support queries using the WITH syntax defined in SQL-99, also called Common Table Expressions.

This has been a feature request for MySQL since January 2006: http://bugs.mysql.com/bug.php?id=16244

Other RDBMS products that support common table expressions:

• Oracle 9i release 2 and later:
  http://www.oracle-base.com/articles/misc/with-clause.php
• Microsoft SQL Server 2005 and later:
  http://msdn.microsoft.com/en-us/library/ms190766(v=sql.90).aspx
• IBM DB2 UDB 8 and later:
  http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.ibm.db2.udb.doc/admin/r0000879.htm
• PostgreSQL 8.4 and later:
  https://www.postgresql.org/docs/current/static/queries-with.html
• Sybase 11 and later:
  http://dcx.sybase.com/1100/en/dbusage_en11/commontblexpr-s-5414852.html
• SQLite 3.8.3 and later:
  http://sqlite.org/lang_with.html
• HSQLDB:
  http://hsqldb.org/doc/guide/dataaccess-chapt.html#dac_with_clause
• Firebird 2.1 and later (the first Open Source DBMS to support recursive queries): http://www.firebirdsql.org/file/documentation/release_notes/html/rlsnotes210.html#rnfb210-cte
• H2 Database (but only recursive):
  http://www.h2database.com/html/advanced.html#recursive_queries
• Informix 14.10 and later: https://www.ibm.com/support/knowledgecenter/SSGU8G_14.1.0/com.ibm.sqls.doc/ids_sqs_with.htm

It's also a common practice when people are building the sql query programmatically, it's just easier to start with 'where 1=1 ' and then appending ' and customer.id=:custId' depending if a customer id is provided. So you can always append the next part of the query starting with 'and ...'.

In case you use math equation like I did you can set it like this:

{math equation="x + y" x=4.4444 y=5.0000 format="%.2f"}

As you can see in the error description your table contains the columns (_id, tast_title, notes, reminder_date_time) and you are trying to add a foreign key from a column "taskCat" but it does not exist in your table!

<div class="headerdivider"></div>

and

.headerdivider {
    border-left: 1px solid #38546d;
    background: #16222c;
    width: 1px;
    height: 80px;
    position: absolute;
    right: 250px;
    top: 10px;
}

Node comes with npm installed so you should have a version of npm. However, npm gets updated more frequently than Node does, so you'll want to make sure it's the latest version.

Try

sudo npm install npm -g

1. Press Win key + X
2. click 'System' link from popup menu
3. click advance setting link (Left panel) in opened 'System setting' window (Control Panel\System and Security\System)
4. Now a window named 'System property' will be open, select 'advance' tab and click on environmental variables
5. Select path variable from 'System Variable' list section. and click edit
6. click new button on newly opened window and paste your Jre folder link(Jre in JDK) click okey , okey , okey
7. re run your program :p

You probably want the isinstance builtin function:

self.data = data if isinstance(data, list) else self.parse(data)

I had trouble getting any of the answers to work as they were based on the older versions of JQuery UI. We're using 1.11.4 (CDN Reference).

Here is my Fiddle with working code: http://jsfiddle.net/6b0p02um/ I ended up splicing together bits from four or five different threads to get mine to work:

    $("#tabs").tabs(); 

    //selects the tab index of the <li> relative to the div it is contained within
    $(".btn_tab3").click(function () {
        $( "#tabs" ).tabs( "option", "active", 2 );
    });         

    //selects the tab by id of the <li>
    $(".btn_tab3_id").click(function () {
      function selectTab(tabName) {
          $("#tabs").tabs("option", "active", $(tabName + "").index());
      }

      selectTab("#li_ui_id_3");
    });

say you define the static getFactorial function inside a CodeController

then this is the way you need to call a static function, because static properties and methods exists with in the class, not in the objects created using the class.

CodeController::getFactorial($index);

----------------UPDATE----------------

To best practice I think you can put this kind of functions inside a separate file so you can maintain with more easily.

to do that

create a folder inside app directory and name it as lib (you can put a name you like).

this folder to needs to be autoload to do that add app/lib to composer.json as below. and run the composer dumpautoload command.

"autoload": {
    "classmap": [
                "app/commands",
                "app/controllers",
                ............
                "app/lib"
    ]
},

then files inside lib will autoloaded.

then create a file inside lib, i name it helperFunctions.php

inside that define the function.

if ( ! function_exists('getFactorial'))
{

    /**
     * return the factorial of a number
     *
     * @param $number
     * @return string
     */
    function getFactorial($date)
    {
        $fact = 1;

        for($i = 1; $i <= $num ;$i++)
            $fact = $fact * $i;

        return $fact;

     }
}

and call it anywhere within the app as

$fatorial_value = getFactorial(225);

Type in pip3 install yaml or like Connor pip3 install strictyaml

From what I understand about your question, before passing the character into the switch statement, you can convert it to lowercase. So you don't have to worry about upper cases because they are automatically converted to lower case. For that you need to use the below function:

Character.toLowerCase(c);

To answer the question:

What is the fastest way to stream live video using JavaScript? Is WebSockets over TCP a fast enough protocol to stream a video of, say, 30fps?

Yes, Websocket can be used to transmit over 30 fps and even 60 fps.

The main issue with Websocket is that it is low-level and you have to deal with may other issues than just transmitting video chunks. All in all it's a great transport for video and also audio.

1) To answer your question:

  String s="Java";
  System.out.println(s.length()); 

If the file is text, and you want to get the text line by line, the easiest way is to use fgets().

char buffer[100];
FILE *fp = fopen("filename", "r");                 // do not use "rb"
while (fgets(buffer, sizeof(buffer), fp)) {
... do something
}
fclose(fp);

A small word of caution, if "do some stuff" means updating the value of the actual property that you visit AND if there is a struct type property along the path from root object to the visited property, the change you made on the property will not be reflected on the root object.

Similar issues arise when a new project has to be created, and you want a different project folder name than the project name.

When you create a new project, it gets stored at

./path/to/pro/ject/YourProject/YourProject.**proj

Let's assume you wanted to have it directly in the ject folder:

./path/to/pro/ject/YourProject.**proj

My workaround to accomplish this is to create the project with the last part of the path as its name, so that it doesn't create an additional directory:

./path/to/pro/ject/ject.**proj

When you now rename the project from within Visual Studio, you achieve the goal without having to leave Visual Studio:

./path/to/pro/ject/YourProject.**proj

The downside of this approach is that you have to adjust the default namespace and the name of the Output binary as well, and that you have to update namespaces in all files that are included within the project template.

Your server's response allows the request to include three specific non-simple headers:

Access-Control-Allow-Headers:origin, x-requested-with, content-type

but your request has a header not allowed by the server's response:

Access-Control-Request-Headers:access-control-allow-origin, content-type

All non-simple headers sent in a CORS request must be explicitly allowed by the Access-Control-Allow-Headers response header. The unnecessary Access-Control-Allow-Origin header sent in your request is not allowed by the server's CORS response. This is exactly what the "...not allowed by Access-Control-Allow-Headers" error message was trying to tell you.

There is no reason for the request to have this header: it does nothing, because Access-Control-Allow-Origin is a response header, not a request header.

Solution: Remove the setRequestHeader call that adds a Access-Control-Allow-Origin header to your request.

Use the following code it worked for me:

# Create the figure
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# Generate the values
x_vals = X_iso[:, 0:1]
y_vals = X_iso[:, 1:2]
z_vals = X_iso[:, 2:3]

# Plot the values
ax.scatter(x_vals, y_vals, z_vals, c = 'b', marker='o')
ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')
ax.set_zlabel('Z-axis')

plt.show()

while X_iso is my 3-D array and for X_vals, Y_vals, Z_vals I copied/used 1 column/axis from that array and assigned to those variables/arrays respectively.

Continuing with what Dave Ward said:

• You can't set the Visible property to false because the control will not be rendered.
• You should use the Style property to set it's display to none.

Page/Control design

<asp:Label runat="server" ID="Label1" Style="display: none;" />

<asp:Button runat="server" ID="Button1" />

Code behind

Somewhere in the load section:

Label label1 = (Label)FindControl("Label1");
((Label)FindControl("Button1")).OnClientClick = "ToggleVisibility('" + label1.ClientID + "')";

Javascript file

function ToggleVisibility(elementID)
{
    var element = document.getElementByID(elementID);

    if (element.style.display = 'none')
    {
        element.style.display = 'inherit';
    }
    else
    {
        element.style.display = 'none';
    }
}

Of course, if you don't want to toggle but just to show the button/label then adjust the javascript method accordingly.

The important point here is that you need to send the information about the ClientID of the control that you want to manipulate on the client side to the javascript file either setting global variables or through a function parameter as in my example.

.so files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.

.a files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar command -- a predecessor of tar that's now just used for making libraries) of the original .o object files.

.la files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?

Static and dynamic libraries each have pros and cons.

Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.

Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.

Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.

Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.

Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.

Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.

Dynamic libraries are especially useful for system libraries, like libc. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.

<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>

Easy as that.

Or without JS

<a href="http://yahoo.com" target="_blank">test</a>

I don't think it's possible to do it in the way you are trying to do it.

Indication of the accepted data format is usually done through adding the extension to the resource name. So, if you have resource like

/resources/resource

and GET /resources/resource returns its HTML representation, to indicate that you want its XML representation instead, you can use following pattern:

/resources/resource.xml

You have to do the accepted content type determination magic on the server side, then.

Or use Javascript as James suggests.

Here is my solution. I first create random numbers with random.uniform, format them in to string with double precision and then convert them back to float. You can adjust the precision by changing '.2f' to '.3f' etc..

import random
from decimal import Decimal

GndSpeedHigh = float(format(Decimal(random.uniform(5, 25)), '.2f'))
GndSpeedLow = float(format(Decimal(random.uniform(2, GndSpeedHigh)), '.2f'))
GndSpeedMean = float(Decimal(format(GndSpeedHigh + GndSpeedLow) / 2, '.2f')))
print(GndSpeedMean)

Try:

extern int testlib(void);

It makes sure that the returned object (which is an RValue at that point) can't be modified. This makes sure the user can't do thinks like this:

myFunc() = Object(...);

That would work nicely if myFunc returned by reference, but is almost certainly a bug when returned by value (and probably won't be caught by the compiler). Of course in C++11 with its rvalues this convention doesn't make as much sense as it did earlier, since a const object can't be moved from, so this can have pretty heavy effects on performance.

You can achieve customized radio buttons in two pure CSS ways

1. Via removing standard appearance using CSS appearance and applying custom appearance. Unfortunately this was doesn't work in IE for Desktop (but works in IE for Windows Phone). Demo:

   _x000D_

   _x000D_

   input[type="radio"] {
     /* remove standard background appearance */
     -webkit-appearance: none;
     -moz-appearance: none;
     appearance: none;
     /* create custom radiobutton appearance */
     display: inline-block;
     width: 25px;
     height: 25px;
     padding: 6px;
     /* background-color only for content */
     background-clip: content-box;
     border: 2px solid #bbbbbb;
     background-color: #e7e6e7;
     border-radius: 50%;
   }
   
   /* appearance for checked radiobutton */
   input[type="radio"]:checked {
     background-color: #93e026;
   }
   
   /* optional styles, I'm using this for centering radiobuttons */
   .flex {
     display: flex;
     align-items: center;
   }

   _x000D_

   <div class="flex">
     <input type="radio" name="radio" id="radio1" />
     <label for="radio1">RadioButton1</label>
   </div>
   <div class="flex">
     <input type="radio" name="radio" id="radio2" />
     <label for="radio2">RadioButton2</label>
   </div>
   <div class="flex">
     <input type="radio" name="radio" id="radio3" />
     <label for="radio3">RadioButton3</label>
   </div>

   _x000D_

   _x000D_
   _x000D_

2. Via hiding radiobutton and setting custom radiobutton appearance to label's pseudoselector. By the way no need for absolute positioning here (I see absolute positioning in most demos). Demo:

   _x000D_

   _x000D_

   *,
   *:before,
   *:after {
     box-sizing: border-box;
   }
   
   input[type="radio"] {
     display: none;
   }
   
   input[type="radio"]+label:before {
     content: "";
     /* create custom radiobutton appearance */
     display: inline-block;
     width: 25px;
     height: 25px;
     padding: 6px;
     margin-right: 3px;
     /* background-color only for content */
     background-clip: content-box;
     border: 2px solid #bbbbbb;
     background-color: #e7e6e7;
     border-radius: 50%;
   }
   
   /* appearance for checked radiobutton */
   input[type="radio"]:checked + label:before {
     background-color: #93e026;
   }
   
   /* optional styles, I'm using this for centering radiobuttons */
   label {
     display: flex;
     align-items: center;
   }

   _x000D_

   <input type="radio" name="radio" id="radio1" />
   <label for="radio1">RadioButton1</label>
   <input type="radio" name="radio" id="radio2" />
   <label for="radio2">RadioButton2</label>
   <input type="radio" name="radio" id="radio3" />
   <label for="radio3">RadioButton3</label>

   _x000D_

   _x000D_
   _x000D_

const __checkIfElementExists__ = __itemFromArray__ => __itemFromArray__.*sameKey* === __outsideObject__.*samekey*;

    if (cartArray.some(checkIfElementExists)) {
        console.log('already exists');
    } else {
        alert('does not exists here')

If the number is stored in a string (which it would be if typed by a user), you can use atoi() to convert it to an integer.

An integer can be assigned directly to a character. A character is different mostly just because how it is interpreted and used.

char c = atoi("61");

Now that the full screen APIs are more widespread and appear to be maturing, why not try Screenfull.js? I used it for the first time yesterday and today our app goes truly full screen in (almost) all browsers!

Be sure to couple it with the :fullscreen pseudo-class in CSS. See https://www.sitepoint.com/use-html5-full-screen-api/ for more.

In my case, I had accidentally named a folder 'samples '. I couldn't see the space when I did 'ls -la'.

Eventually I realized this when I tried tabbing to autocomplete and saw 'samples\ /'.

To fix this I ran

mv samples\  samples

I had the same problem with a client of my company, the problem was that the driver sqljdbc4.jar, tries a convertion of character between the database and the driver. Each time that it did a request to the database, now you can imagine 650 connections concurrently, this did my sistem very very slow, for avoid this situation i add at the String of connection the following parameter:

 SendStringParametersAsUnicode=false, then te connection must be something like url="jdbc:sqlserver://IP:PORT;DatabaseName=DBNAME;SendStringParametersAsUnicode=false"

After that, the system is very very fast, as the users are very happy with the change, i hope my input be of same.

From http://php.quicoto.com/inline-ifelse-statement-ngclick-angularjs/, this is how you do it, if you really have to:

ng-click="variable = (condition=='X' ? 'Y' : 'X')"

Give this a try:

PS> $nl = [Environment]::NewLine
PS> gci hklm:\software\microsoft\windows\currentversion\uninstall | 
        ForEach { $_.GetValue("DisplayName") } | Where {$_} | Sort |
        Foreach {"$_$nl"} | Out-File addrem.txt -Enc ascii

It yields the following text in my addrem.txt file:

Adobe AIR

Adobe Flash Player 10 ActiveX

...

Note: on my system, GetValue("DisplayName") returns null for some entries, so I filter those out. BTW, you were close with this:

ForEach-Object -Process { "$_.GetValue("DisplayName") `n" }

Except that within a string, if you need to access a property of a variable, that is, "evaluate an expression", then you need to use subexpression syntax like so:

Foreach-Object -Process { "$($_.GetValue('DisplayName'))`r`n" }

Essentially within a double quoted string PowerShell will expand variables like $_, but it won't evaluate expressions unless you put the expression within a subexpression using this syntax:

$(`<Multiple statements can go in here`>).

Try this:

$.ajax({
    type: 'get',
    url: 'manageproducts.do',
    data: 'option=1',
    success: function(data) {

        availableProductNames = data.split(",");

        alert(availableProductNames);

    }
});

Also You have a few errors in your sample code, not sure if that was causing the error or it was just a typo upon entering the question.

Like this

class CustomDictOne(dict):
   def __init__(self,*arg,**kw):
      super(CustomDictOne, self).__init__(*arg, **kw)

Now you can use the built-in functions, like dict.get() as self.get().

You do not need to wrap a hidden self._dict. Your class already is a dict.

Have a look at the EditorConfig plugin.

By using the plugin you can have settings specific for various projects. Visual Studio Code also has IntelliSense built-in for .editorconfig files.

How about something like this:

import os


def readlines_reverse(filename):
    with open(filename) as qfile:
        qfile.seek(0, os.SEEK_END)
        position = qfile.tell()
        line = ''
        while position >= 0:
            qfile.seek(position)
            next_char = qfile.read(1)
            if next_char == "\n":
                yield line[::-1]
                line = ''
            else:
                line += next_char
            position -= 1
        yield line[::-1]


if __name__ == '__main__':
    for qline in readlines_reverse(raw_input()):
        print qline

Since the file is read character by character in reverse order, it will work even on very large files, as long as individual lines fit into memory.

I had the same error in a demo app that was concerned with security and login state. None of the other solutions helped, but simply opening a new anonymous browser window did the trick.

Basically, there were cookies and tokens left from a previous version of the app which put AngularJS in a state that it was never supposed to reach. Hence the areq assertions failed.

I learned a really cool way of converting a given Date object to a Unix timestamp from the source code of JQuery Cookie the other day.

Here's an example:

var date = new Date();
var timestamp = +date;

If you truly want to discard the commits you've made locally, i.e. never have them in the history again, you're not asking how to pull - pull means merge, and you don't need to merge. All you need do is this:

# fetch from the default remote, origin
git fetch
# reset your current branch (master) to origin's master
git reset --hard origin/master

I'd personally recommend creating a backup branch at your current HEAD first, so that if you realize this was a bad idea, you haven't lost track of it.

If on the other hand, you want to keep those commits and make it look as though you merged with origin, and cause the merge to keep the versions from origin only, you can use the ours merge strategy:

# fetch from the default remote, origin
git fetch
# create a branch at your current master
git branch old-master
# reset to origin's master
git reset --hard origin/master
# merge your old master, keeping "our" (origin/master's) content
git merge -s ours old-master

Both node-schedule and node-cron we can use to implement cron-based schedullers.

NOTE : for generating cron expressions , you can use this cron_maker

The alert() dialog is not rendered in HTML, and thus the HTML you have embedded is meaningless.

You'd need to use a custom modal to achieve that.

First get the item height in pixels

View rowItem = adapter.getView(0, null, scrollView);   
rowItem.measure(0, 0);    
int heightOfItem = rowItem.getMeasuredHeight();

then simply

Display display = getWindowManager().getDefaultDisplay();    
DisplayMetrics displayMetrics = new DisplayMetrics();    
display.getMetrics(displayMetrics);    
scrollView.getLayoutParams().height = (int)((heightOfItem * 3)*displayMetrics .density);

use TCG\Voyager\Models\Jobtype;

class FormController extends Controller
{
public function index()
{
   $category = Jobtype::all();
   return view('contact', compact('category'));

}
}

• use your model
• assign it to a variabel
• pass the object to the view Here is an example:

As an aid to understanding why extending an Enum is not reasonable at the language implementation level to consider what would happen if you passed an instance of the extended Enum to a routine that only understands the base Enum. A switch that the compiler promised had all cases covered would in fact not cover those extended Enum values.

This further emphasizes that Java Enum values are not integers such as C's are, for instances: to use a Java Enum as an array index you must explicitly ask for its ordinal() member, to give a java Enum an arbitrary integer value you must add an explicit field for that and reference that named member.

This is not a comment on the OP's desire, just on why Java ain't never going to do it.

If you want to save the changes on the log messages, use the batch script from the answer above from @patmortech (https://stackoverflow.com/a/468475),
who copied the script from https://stackoverflow.com/a/68850,
and add these lines between if "%bIsEmpty%" == "true" goto ERROR_EMPTY and goto :eofbefore:

set outputFile=%repos%\log-change-history.txt

echo User '%user%' changes log message in rev %rev% on %date% %time%.>>%outputFile%
echo ----- Old message: ----->>%outputFile%
svnlook propget --revprop %repos% svn:log -r %rev% >>%outputFile%
echo.>>%outputFile%
echo ----- New message: ----->>%outputFile%
for /f "tokens=*" %%g in ('find /V ""') do (echo %%g >>%outputFile%)
echo ---------->>%outputFile%
echo.>>%outputFile%

It will create a text file log-change-history.txt in the repo folder on the server and append each log change notification.

this is best solution for me :)

$i=0;
foreach() if ($i < yourlimitnumber) {

$i +=1;
}

However, if you find yourself using nested cursor FOR loops, it is almost always more efficient to let the database join the two results for you. After all, relational databases are really, really good at joining. I'm guessing here at what your tables look like and how they relate based on the code you posted but something along the lines of

FOR x IN (SELECT *
            FROM all_users,
                 org
           WHERE length(all_users.username) = 3
             AND all_users.username = org.username )
LOOP
  <<do something>>
END LOOP;

SQL Server recognizes 'TRUE' and 'FALSE' as bit values. So, use a bit data type!

declare @var bit
set @var = 'true'
print @var

That returns 1.

Try this:

X (\(Y\))? Z

This has already been answered very well technically, but let me give a concrete example of how it's extremely useful:

Lets say you have two tables, Customer and Order. Customers have many Orders.

I want to create a view that gives me details about customers, and the most recent order they've made. With just JOINS, this would require some self-joins and aggregation which isn't pretty. But with Cross Apply, its super easy:

SELECT *
FROM Customer
CROSS APPLY (
  SELECT TOP 1 *
  FROM Order
  WHERE Order.CustomerId = Customer.CustomerId
  ORDER BY OrderDate DESC
) T

Try

//*[text()='qwerty'] because . is your current element

Try

$query = mysql_query("SELECT * FROM users WHERE name = 'Admin' ")or die(mysql_error());

and check if this throw any error.

Then use while($rows = mysql_fetch_assoc($query)):

And finally display it as

echo $name . "<br/>" . $address . "<br/>" . $email . "<br/>" . $subject . "<br/>" . $comment . "<br/><br/>" . ;

Do not user mysql_* as its deprecated.

See THIS previous SO post on using a variable on the replacement side of s///in Perl. Look both at the accepted answer and the rebuttal answer.

What you are trying to do is possible with the s///ee form that performs a double eval on the right hand string. See perlop quote like operators for more examples.

Be warned that there are security impilcations of evaland this will not work in taint mode.

Hope this helps you

Using Terminal First point your location where andriod sdk is loacted

eg: C:\Users\AppData\Local\Android\sdk\platform-tools>

then check the list of devices attached Using

 adb devices

and then run this command to copy the file from device to your system

adb -s YOUR_DEVICE_ID shell run-as YOUR_PACKAGE_NAME chmod -R 777 /data/data/YOUR_PACKAGE_NAME/databases && adb -s YOUR_DEVICE_ID shell "mkdir -p /sdcard/tempDB" && adb -s YOUR_DEVICE_ID shell "cp -r /data/data/YOUR_PACKAGE_NAME/databases/ /sdcard/tempDB/." && adb -s YOUR_DEVICE_ID pull sdcard/tempDB/ && adb -s YOUR_DEVICE_ID shell "rm -r /sdcard/tempDB/*"

You can find the database file in this path

 Android\sdk\platform-tools\tempDB\databases

Main is just like any other function and argc and argv are just like any other function arguments, the difference is that main is called from C Runtime and it passes the argument to main, But C Runtime is defined in c library and you cannot modify it, So if we do execute program on shell or through some IDE, we need a mechanism to pass the argument to main function so that your main function can behave differently on the runtime depending on your parameters. The parameters are argc , which gives the number of arguments and argv which is pointer to array of pointers, which holds the value as strings, this way you can pass any number of arguments without restricting it, it's the other way of implementing var args.

the issue happened with me, I resolved by removing the scope tag only and built successfully.

Windows solution: Control + C.

Macbook solution: Control (^) + C.

Another way is to open a terminal, type top, write down the PID of the process that you would like to kill and then type on the terminal: kill -9 <pid>

$_='~s/blue/red/g';

Uh, what??

Just

s/blue/red/g;

or, if you insist on using a variable (which is not necessary when using $_, but I just want to show the right syntax):

$_ =~ s/blue/red/g;

Method Object JComboBox.getSelectedItem() returns a value that is wrapped by Object type so you have to cast it accordingly.

Syntax:

YourType varName = (YourType)comboBox.getSelectedItem();`
String value = comboBox.getSelectedItem().toString();

Try this

original_object = Foo.objects.get(pk="foo")
v = vars(original_object)
v.pop("pk")
new_object = Foo(**v)
new_object.save()

You can play here with different types and check the output,

Demo

export class ParentCmp {
  myVar:stirng="micronyks";
  myVal:any;
  myArray:Array[]=[1,2,3];
  myArr:Array[];

    constructor() {
      if(this.myVar){
         console.log('has value')     // answer
      }
      else{
        console.log('no value');
      }

      if(this.myVal){
         console.log('has value') 
      }
      else{
        console.log('no value');      //answer
      }


       if(this.myArray){
          console.log('has value')    //answer
       }
       else{
          console.log('no value');
       }

       if(this.myArr){
             console.log('has value')
       }
       else{
             console.log('no value');  //answer
       }
    } 

}

It seems to me that simply: ls -lt mydirectory does the job...

As dfsq said i just had to use removeClass("hide") instead of toggle()

See The Java Tutorials: Strings.

public class StringDemo {
    public static void main(String[] args) {
        String palindrome = "Dot saw I was Tod";
        int len = palindrome.length();
        char[] tempCharArray = new char[len];
        char[] charArray = new char[len];

        // put original string in an array of chars
        for (int i = 0; i < len; i++) {
            tempCharArray[i] = palindrome.charAt(i);
        } 

        // reverse array of chars
        for (int j = 0; j < len; j++) {
            charArray[j] = tempCharArray[len - 1 - j];
        }

        String reversePalindrome =  new String(charArray);
        System.out.println(reversePalindrome);
    }
}

Put the length into int len and use for loop.

lace to store your loaded class definition and metadata. If a large code-base project is loaded, the insufficient Perm Gen size will cause the popular Java.Lang.OutOfMemoryError: PermGen.

Q: The programming model is event driven, especially the way it handles I/O.

Correct. It uses call-backs, so any request to access the file system would cause a request to be sent to the file system and then Node.js would start processing its next request. It would only worry about the I/O request once it gets a response back from the file system, at which time it will run the callback code. However, it is possible to make synchronous I/O requests (that is, blocking requests). It is up to the developer to choose between asynchronous (callbacks) or synchronous (waiting).

Q: It uses JavaScript and the parser is V8.

Yes

Q: It can be easily used to create concurrent server applications.

Yes, although you'd need to hand-code quite a lot of JavaScript. It might be better to look at a framework, such as http://www.easynodejs.com/ - which comes with full online documentation and a sample application.

You can include your header function wherever you like, as long as NO html and/or text has been printed to standard out.

For more information and usage: http://php.net/manual/en/function.header.php

I see in your code that you echo() out some text in case of error or success. Don't do that: you can't. You can only redirect OR show the text. If you show the text you'll then fail to redirect.

You can also try this way:

<?php
   echo "<script>console.log('$variableName')</script>";
?>

Views are acceptable when you need to ensure that complex logic is followed every time. For instance, we have a view that creates the raw data needed for all financial reporting. By having all reports use this view, everyone is working from the same data set, rather than one report using one set of joins and another forgetting to use one which gives different results.

Views are acceptable when you want to restrict users to a particular subset of data. For instance, if you do not delete records but only mark the current one as active and the older versions as inactive, you want a view to use to select only the active records. This prevents people from forgetting to put the where clause in the query and getting bad results.

Views can be used to ensure that users only have access to a set of records - for instance, a view of the tables for a particular client and no security rights on the tables can mean that the users for that client can only ever see the data for that client.

Views are very helpful when refactoring databases.

Views are not acceptable when you use views to call views which can result in horrible performance (at least in SQL Server). We almost lost a multimillion dollar client because someone chose to abstract the database that way and performance was horrendous and timeouts frequent. We had to pay for the fix too, not the client, as the performance issue was completely our fault. When views call views, they have to completely generate the underlying view. I have seen this where the view called a view which called a view and so many millions of records were generated in order to see the three the user ultimately needed. I remember one of these views took 8 minutes to do a simple count(*) of the records. Views calling views are an extremely poor idea.

Views are often a bad idea to use to update records as usually you can only update fields from the same table (again this is SQL Server, other databases may vary). If that's the case, it makes more sense to directly update the tables anyway so that you know which fields are available.

eval isn't always evil. There are times where it's perfectly appropriate.

However, eval is currently and historically massively over-used by people who don't know what they're doing. That includes people writing JavaScript tutorials, unfortunately, and in some cases this can indeed have security consequences - or, more often, simple bugs. So the more we can do to throw a question mark over eval, the better. Any time you use eval you need to sanity-check what you're doing, because chances are you could be doing it a better, safer, cleaner way.

To give an all-too-typical example, to set the colour of an element with an id stored in the variable 'potato':

eval('document.' + potato + '.style.color = "red"');

If the authors of the kind of code above had a clue about the basics of how JavaScript objects work, they'd have realised that square brackets can be used instead of literal dot-names, obviating the need for eval:

document[potato].style.color = 'red';

...which is much easier to read as well as less potentially buggy.

(But then, someone who /really/ knew what they were doing would say:

document.getElementById(potato).style.color = 'red';

which is more reliable than the dodgy old trick of accessing DOM elements straight out of the document object.)

If you want a very easy way to do this, you can lean on existing PHP functions. This is the code I use:

substr( sha1( time() ), 0, 15 )

time() gives you the current time in seconds since epoch, sha1() encrypts it to a string of 0-9a-f, and substr() lets you choose a length. You don't have to start at character 0, and whatever the difference is between the two numbers will be the length of the string.

for 1.0.4:

io.sockets.on('connection', function (socket) {
  var socketId = socket.id;
  var clientIp = socket.request.connection.remoteAddress;

  console.log(clientIp);
});

Thanks for your feed back got it to work I used the sshpass tool.

If the attribute you want to change doesn't exist or has been accidentally removed, then an exception occurs. I suggest you first create a new attribute and send it to a function like the following:

private void SetAttrSafe(XmlNode node,params XmlAttribute[] attrList)
    {
        foreach (var attr in attrList)
        {
            if (node.Attributes[attr.Name] != null)
            {
                node.Attributes[attr.Name].Value = attr.Value;
            }
            else
            {
                node.Attributes.Append(attr);
            }
        }
    }

Usage:

   XmlAttribute attr = dom.CreateAttribute("name");
   attr.Value = value;
   SetAttrSafe(node, attr);

Set proper constraint and update delegate methods as:

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

This will resolve dynamic cell height issue. IF not you need to check constraints.

If you want to know if list element at index i is set or not, you can simply check the following:

if len(l)<=i:
    print ("empty")

If you are looking for something like what is a NULL-Pointer or a NULL-Reference in other languages, Python offers you None. That is you can write:

l[0] = None # here, list element at index 0 has to be set already
l.append(None) # here the list can be empty before
# checking
if l[i] == None:
    print ("list has actually an element at position i, which is None")

On Windows 7 , the only thing that worked for me is this. Go to Device Manager -> Under Android Phone -> Right Click and select 'enable'

If you doing from windows folder, I mean if you are using the kafka from windows machine

kafka-console-consumer.bat --bootstrap-server localhost:9092 --<topic-name> test --from-beginning

YES the warning is backwards.

And in fact it shouldn't even be a warning in the first place. Because all this warning is saying (but backwards unfortunately) is that the CRLF characters in your file with Windows line endings will be replaced with LF's on commit. Which means it's normalized to the same line endings used by *nix and MacOS.

Nothing strange is going on, this is exactly the behavior you would normally want.

This warning in it's current form is one of two things:

1. An unfortunate bug combined with an over-cautious warning message, or
2. A very clever plot to make you really think this through...
