curl -s http://google.com > temp.html

works for curl version 7.19.5 on Ubuntu 9.10 (no progress bar). But if for some reason that does not work on your platform, you could always redirect stderr to /dev/null:

curl  http://google.com 2>/dev/null > temp.html

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

If someone looking for calling a script with arguments

import subprocess

val = subprocess.check_call("./script.sh '%s'" % arg, shell=True)

Remember to convert the args to string before passing, using str(arg).

This can be used to pass as many arguments as desired:

subprocess.check_call("./script.ksh %s %s %s" % (arg1, str(arg2), arg3), shell=True)

From the documentation for strtotime():

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.

Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:

$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16

See sys.exit. That function will quit your program with the given exit status.

I think you can almost do exactly what you thought would be ideal, using the statsmodels package which was one of pandas' optional dependencies before pandas' version 0.20.0 (it was used for a few things in pandas.stats.)

>>> import pandas as pd
>>> import statsmodels.formula.api as sm
>>> df = pd.DataFrame({"A": [10,20,30,40,50], "B": [20, 30, 10, 40, 50], "C": [32, 234, 23, 23, 42523]})
>>> result = sm.ols(formula="A ~ B + C", data=df).fit()
>>> print(result.params)

I am not sure about your DBMS. So, I created a temporary table in Redshift and from my experience, I think this query should return what you are looking for:

select min(Id), distinct MailId, EmailAddress, Name
    from yourTableName
    group by MailId, EmailAddress, Name

I see that I am using a GROUP BY clause but you still won't have two rows against any particular MailId.

I understand that this question is old, but there is a good solution for it in HTML5. You can wrap it all in a <figure></figure> tag. The code would look something like this:

<div id="wrapper">
<figure>

<a href="mailto:[email protected]">
<img id="fblogo" border="0" alt="Mail" src="http://olympiahaacht.be/wp- 
content/uploads/2012/07/email-icon-e1343123697991.jpg"/>
</a>

content/uploads/2012/04/FacebookButtonRevised-e1334605872360.jpg"/>
</a>

</figure>
</div>

and the CSS:

#wrapper{
 text-align:center;
}

I also stumbled over this problem recently. Here is my solution. I wanted to avoid recursion, so I used a while loop.

Because of the adds and removes in arbitrary places on the list, I went with the LinkedList implementation.

/* traverses tree starting with given node */
  private static List<Node> traverse(Node n)
  {
    return traverse(Arrays.asList(n));
  }

  /* traverses tree starting with given nodes */
  private static List<Node> traverse(List<Node> nodes)
  {
    List<Node> open = new LinkedList<Node>(nodes);
    List<Node> visited = new LinkedList<Node>();

    ListIterator<Node> it = open.listIterator();
    while (it.hasNext() || it.hasPrevious())
    {
      Node unvisited;
      if (it.hasNext())
        unvisited = it.next();
      else
        unvisited = it.previous();

      it.remove();

      List<Node> children = getChildren(unvisited);
      for (Node child : children)
        it.add(child);

      visited.add(unvisited);
    }

    return visited;
  }

  private static List<Node> getChildren(Node n)
  {
    List<Node> children = asList(n.getChildNodes());
    Iterator<Node> it = children.iterator();
    while (it.hasNext())
      if (it.next().getNodeType() != Node.ELEMENT_NODE)
        it.remove();
    return children;
  }

  private static List<Node> asList(NodeList nodes)
  {
    List<Node> list = new ArrayList<Node>(nodes.getLength());
    for (int i = 0, l = nodes.getLength(); i < l; i++)
      list.add(nodes.item(i));
    return list;
  }

-z string True if the string is null (an empty string)

You might try passing actual types instead of strings.

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime, datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

But it's going to be really hard to diagnose this without any of your data to tinker with.

And really, you probably want pandas to parse the the dates into TimeStamps, so that might be:

pd.read_csv(file, sep='\t', header=None, names=headers, parse_dates=True)

Did you dispatch the event correctly?

function simulateKeyEvent(character) {
  var evt = document.createEvent("KeyboardEvent");
  (evt.initKeyEvent || evt.initKeyboardEvent)("keypress", true, true, window,
                    0, 0, 0, 0,
                    0, character.charCodeAt(0)) 
  var canceled = !body.dispatchEvent(evt);
  if(canceled) {
    // A handler called preventDefault
    alert("canceled");
  } else {
    // None of the handlers called preventDefault
    alert("not canceled");
  }
}

If you use jQuery, you could do:

function simulateKeyPress(character) {
  jQuery.event.trigger({ type : 'keypress', which : character.charCodeAt(0) });
}

Here is a simple programe to capture a image from using laptop default camera.I hope that this will be very easy method for all.

import cv2

# 1.creating a video object
video = cv2.VideoCapture(0) 
# 2. Variable
a = 0
# 3. While loop
while True:
    a = a + 1
    # 4.Create a frame object
    check, frame = video.read()
    # Converting to grayscale
    #gray = cv2.cvtColor(frame,cv2.COLOR_BGR2GRAY)
    # 5.show the frame!
    cv2.imshow("Capturing",frame)
    # 6.for playing 
    key = cv2.waitKey(1)
    if key == ord('q'):
        break
# 7. image saving
showPic = cv2.imwrite("filename.jpg",frame)
print(showPic)
# 8. shutdown the camera
video.release()
cv2.destroyAllWindows

Sorry for adding another answer to an old post but I usually get a scroll event very well by using this code (it works at least on 6.1)

element.addEventListener('scroll', function() {
    console.log(this.scrollTop);
});

// This is the magic, this gives me "live" scroll events
element.addEventListener('gesturechange', function() {});

And that works for me. Only thing it doesn't do is give a scroll event for the deceleration of the scroll (Once the deceleration is complete you get a final scroll event, do as you will with it.) but if you disable inertia with css by doing this

-webkit-overflow-scrolling: none;

You don't get inertia on your elements, for the body though you might have to do the classic

document.addEventListener('touchmove', function(e) {e.preventDefault();}, true);

If you are already in an Angular project you could use $filter('date').

For example:

var myDate = new Date();
var myWeek = $filter('date')(myDate, 'ww');

Use varchar instead of VAR_CHAR and omit the comma in the last line i.e.phone INT NOT NULL );. The last line during creating table is kept "comma free". Ex:- CREATE TABLE COMPUTER ( Model varchar(50) ); Here, since we have only one column ,that's why there is no comma used during entire code.

The USAGE-privilege in mysql simply means that there are no privileges for the user 'phpadmin'@'localhost' defined on global level *.*. Additionally the same user has ALL-privilege on database phpmyadmin phpadmin.*.

So if you want to remove all the privileges and start totally from scratch do the following:

• Revoke all privileges on database level:

  REVOKE ALL PRIVILEGES ON phpmyadmin.* FROM 'phpmyadmin'@'localhost';

• Drop the user 'phpmyadmin'@'localhost'

  DROP USER 'phpmyadmin'@'localhost';

Above procedure will entirely remove the user from your instance, this means you can recreate him from scratch.

To give you a bit background on what described above: as soon as you create a user the mysql.user table will be populated. If you look on a record in it, you will see the user and all privileges set to 'N'. If you do a show grants for 'phpmyadmin'@'localhost'; you will see, the allready familliar, output above. Simply translated to "no privileges on global level for the user". Now your grant ALL to this user on database level, this will be stored in the table mysql.db. If you do a SELECT * FROM mysql.db WHERE db = 'nameofdb'; you will see a 'Y' on every priv.

Above described shows the scenario you have on your db at the present. So having a user that only has USAGE privilege means, that this user can connect, but besides of SHOW GLOBAL VARIABLES; SHOW GLOBAL STATUS; he has no other privileges.

If you are trying to track down which line caused an error, if you right-click in the Python shell where the line error is displayed it will come up with a "Go to file/line" which takes you directly to the line in question.

Summary (Some examples of how to define methods in classes in python)

#!/usr/bin/env python   # (if running from bash)

class Class1(object):

    def A(self, arg1):
        print arg1
        # this method requires an instance of Class1   
        # can access self.variable_name, and other methods in Class1

    @classmethod
    def B(cls, arg1):
        cls.C(arg1)
        # can access methods B and C in Class1 

    @staticmethod
    def C(arg1):
        print arg1
        # can access methods B and C in Class1 
        # (i.e. via Class1.B(...) and Class1.C(...))

Example

my_obj=Class1()

my_obj.A("1")
# Class1.A("2") # TypeError: method A() must be called with Class1 instance

my_obj.B("3")
Class1.B("4")
my_obj.C("5")
Class1.C("6")`

Disconnecting and reconnecting to the current network worked for me.

You can also use the regroup template tag to group by attributes. From the docs:

cities = [
    {'name': 'Mumbai', 'population': '19,000,000', 'country': 'India'},
    {'name': 'Calcutta', 'population': '15,000,000', 'country': 'India'},
    {'name': 'New York', 'population': '20,000,000', 'country': 'USA'},
    {'name': 'Chicago', 'population': '7,000,000', 'country': 'USA'},
    {'name': 'Tokyo', 'population': '33,000,000', 'country': 'Japan'},
]

...

{% regroup cities by country as country_list %}

<ul>
    {% for country in country_list %}
        <li>{{ country.grouper }}
            <ul>
            {% for city in country.list %}
                <li>{{ city.name }}: {{ city.population }}</li>
            {% endfor %}
            </ul>
        </li>
    {% endfor %}
</ul>

Looks like this:

• India
  • Mumbai: 19,000,000
  • Calcutta: 15,000,000
• USA
  • New York: 20,000,000
  • Chicago: 7,000,000
• Japan
  • Tokyo: 33,000,000

It also works on QuerySets I believe.

source: https://docs.djangoproject.com/en/2.1/ref/templates/builtins/#regroup

edit: note the regroup tag does not work as you would expect it to if your list of dictionaries is not key-sorted. It works iteratively. So sort your list (or query set) by the key of the grouper before passing it to the regroup tag.

Are you running this on the Cassini (vs dev server) or on IIS with a cert installed? I have had issues in the past trying to hook up secure endpoints on the dev web server.

Here is the binding configuration that has worked for me in the past. Instead of basicHttpBinding, it uses wsHttpBinding. I don't know if that is a problem for you.

<!-- Binding settings for HTTPS endpoint -->
<binding name="WsSecured">
    <security mode="Transport">
        <transport clientCredentialType="None" />
        <message clientCredentialType="None"
            negotiateServiceCredential="false"
            establishSecurityContext="false" />
    </security>
</binding>

and the endpoint

<endpoint address="..." binding="wsHttpBinding"
    bindingConfiguration="WsSecured" contract="IYourContract" />

Also, make sure you change the client configuration to enable Transport security.

Try this

Cast('7/7/2011' as datetime)

and

Convert(varchar(30),'7/7/2011',102)

See CAST and CONVERT (Transact-SQL) for more details.

Try these steps

1. Run this command in powershell --->bcdedit /set hypervisorlaunchtype auto
2. Restart your PC
3. Now try docker --version in cmd line

My Scenario: I had an list of string, in which I had to append a string given by a user and scroll to the end of the list automatically. I had fixed height of the display of the list, after which it should overflow.

I tried @Jeremy Ruten's answer, it worked, but it was scrolling to the (n-1)th element. If anybody is facing this type of issue, you can use setTimeOut() method workaround. You need to modify the code to below:

setTimeout(() => {
    var objDiv = document.getElementById('div_id');
    objDiv.scrollTop = objDiv.scrollHeight
}, 0)

Here is the StcakBlitz link I have created which shows the problem and its solution : https://stackblitz.com/edit/angular-ivy-x9esw8

You could also use a pseudo class selector in your CSS like this:

.desc:not(:first-child) {
    display: none;
}

That will not apply the class to the first element with the class .desc.

Here's a JSFiddle with an example: http://jsfiddle.net/YYTFT/, and this is a good source to explain pseudo class selectors: http://css-tricks.com/pseudo-class-selectors/

And the reason I want to have the name of the function is because I want to create fun_dict without writing the names of the functions twice, since that seems like a good way to create bugs.

For this purpose you have a wonderful getattr function, that allows you to get an object by known name. So you could do for example:

funcs.py:

def func1(): pass
def func2(): pass

main.py:

import funcs
option = command_line_option()
getattr(funcs, option)()

ComponentWillReceiveProps() is going to be deprecated in the future due to bugs and inconsistencies. An alternative solution for re-rendering a component on props change is to use ComponentDidUpdate() and ShouldComponentUpdate().

ComponentDidUpdate() is called whenever the component updates AND if ShouldComponentUpdate() returns true (If ShouldComponentUpdate() is not defined it returns true by default).

shouldComponentUpdate(nextProps){
    return nextProps.changedProp !== this.state.changedProp;
}

componentDidUpdate(props){
    // Desired operations: ex setting state
}

This same behavior can be accomplished using only the ComponentDidUpdate() method by including the conditional statement inside of it.

componentDidUpdate(prevProps){
    if(prevProps.changedProp !== this.props.changedProp){
        this.setState({          
            changedProp: this.props.changedProp
        });
    }
}

If one attempts to set the state without a conditional or without defining ShouldComponentUpdate() the component will infinitely re-render

When I align elements in center I use the bootstrap class text-center:

<div class="text-center">Centered content goes here</div>

I find the following solution simpler than the other bit fiddling algorithms I've seen in here.

unsigned char reverse_byte(char a)
{

  return ((a & 0x1)  << 7) | ((a & 0x2)  << 5) |
         ((a & 0x4)  << 3) | ((a & 0x8)  << 1) |
         ((a & 0x10) >> 1) | ((a & 0x20) >> 3) |
         ((a & 0x40) >> 5) | ((a & 0x80) >> 7);
}

It gets every bit in the byte, and shifts it accordingly, starting from the first to the last.

Explanation:

   ((a & 0x1) << 7) //get first bit on the right and shift it into the first left position 
 | ((a & 0x2) << 5) //add it to the second bit and shift it into the second left position
  //and so on

Object to array

$array = (array) $players_Obj;  

$object = new StdClass;
$object->foo = 1;
$object->bar = 2;

var_dump( (array) $object );

Output:

array(2) {
    'foo' => int(1)
    'bar' => int(2)
}

Some people have had issues with it, and disabled it, but as a general rule, if it aint broke...

Adding on to @Alexandre Aimbiré's answer - sometimes you may need to specify z-index:1 to have the element always on top while scrolling. Like this:

position: -webkit-sticky; /* Safari & IE */
position: sticky;
top: 0;
z-index: 1;

When you have related tables you often have one-to-many or many-to-many relationships. So when you join to TableB each record in TableA many have multiple records in TableB. This is normal and expected.

Now at times you only need certain columns and those are all the same for all the records, then you would need to do some sort of group by or distinct to remove the duplicates. Let's look at an example:

TableA
Id Field1
1  test
2  another test

TableB
ID Field2 field3
1  Test1  something
1  test1  More something
2  Test2  Anything

So when you join them and select all the files you get:

select * 
from tableA a 
join tableb b on a.id = b.id

a.Id a.Field1        b.id   b.field2  b.field3
1    test            1      Test1     something
1    test            1      Test1     More something
2    another test 2  2      Test2     Anything

These are not duplicates because the values of Field3 are different even though there are repeated values in the earlier fields. Now when you only select certain columns the same number of records are being joined together but since the columns with the different information is not being displayed they look like duplicates.

select a.Id, a.Field1,  b.field2
from tableA a 
join tableb b on a.id = b.id

a.Id a.Field1       b.field2  
1    test           Test1     
1    test           Test1 
2    another test   Test2

This appears to be duplicates but it is not because of the multiple records in TableB.

You normally fix this by using aggregates and group by, by using distinct or by filtering in the where clause to remove duplicates. How you solve this depends on exactly what your business rule is and how your database is designed and what kind of data is in there.

Yes, it is possible.

try:
   ...
except FirstException:
   handle_first_one()

except SecondException:
   handle_second_one()

except (ThirdException, FourthException, FifthException) as e:
   handle_either_of_3rd_4th_or_5th()

except Exception:
   handle_all_other_exceptions()

See: http://docs.python.org/tutorial/errors.html

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)

Although an oldie, what forget is that they should wrap their code block and then catch the error and then test...

function checkup( t ){
  try{
    for(p in t){
      if( p.hasOwnProperty( t ) ){
        return true;
      }
    }
    return false;
  }catch(e){
    console.log("ERROR : "+e);
    return e;
  }
}

So you really don't have to check for a potential problem before hand, you simply catch it and then deal with it how you want.

The best approach from a performance perspective is probably to use a one or two arrays. Copy the list to an array, do operations on the array, and then build a new list from the array. Accessing an array element is faster than accessing a list item, and conversions between a List<T> and a T[] can use a fast "bulk copy" operation which avoids the overhead associated accessing individual items.

For example, suppose you have a List<string> and wish to have every string in the list which starts with T be followed by an item "Boo", while every string that starts with "U" is dropped entirely. An optimal approach would probably be something like:

int srcPtr,destPtr;
string[] arr;

srcPtr = theList.Count;
arr = new string[srcPtr*2];
theList.CopyTo(arr, theList.Count); // Copy into second half of the array
destPtr = 0;
for (; srcPtr < arr.Length; srcPtr++)
{
  string st = arr[srcPtr];
  char ch = (st ?? "!")[0]; // Get first character of string, or "!" if empty
  if (ch != 'U')
    arr[destPtr++] = st;
  if (ch == 'T')
    arr[destPtr++] = "Boo";
}
if (destPtr > arr.Length/2) // More than half of dest. array is used
{
  theList = new List<String>(arr); // Adds extra elements
  if (destPtr != arr.Length)
    theList.RemoveRange(destPtr, arr.Length-destPtr); // Chop to proper length
}
else
{
  Array.Resize(ref arr, destPtr);
  theList = new List<String>(arr); // Adds extra elements
}

It would have been helpful if List<T> provided a method to construct a list from a portion of an array, but I'm unaware of any efficient method for doing so. Still, operations on arrays are pretty fast. Of note is the fact that adding and removing items from the list does not require "pushing" around other items; each item gets written directly to its appropriate spot in the array.

You have to call close() on the GZIPOutputStream before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush() probably won't help ... though calling finish() instead of close() should work. Look at the javadocs.)

Here's the correct code (in Java);

package test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

public class GZipTest {

    public static void main(String[] args) throws
                FileNotFoundException, IOException {
        String name = "/tmp/test";
        GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
        gz.write(10);
        gz.close();       // Remove this to reproduce the reported bug
        System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
    }
}

(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)

DateTime values in T-SQL are stored as floats. You can just subtract the dates from each other and you now have a new date that is the timespan between them.

declare @birthdate datetime
set @birthdate = '6/15/1974'

--age in years - short version
print year(getdate() - @birthdate) - year(0)

--age in years - visualization
declare @mindate datetime
declare @span datetime

set @mindate = 0
set @span = getdate() - @birthdate

print @mindate
print @birthdate
print getdate()
print @span
--substract minyear from spanyear to get age in years
print year(@span) - year(@mindate)
print month(@span)
print day(@span)

1. Indexed fields (fields with numerical keys) are stored as a holy array inside the object. Therefore lookup time is O(1)

2. Same for a lookup array it's O(1)

3. Iterating through an array of objects and testing their ids against the provided one is a O(n) operation.

Spring Data JpaRepository

The Spring Data JpaRepository defines the following two methods:

• getOne, which returns an entity proxy that is suitable for setting a @ManyToOne or @OneToOne parent association when persisting a child entity.
• findById, which returns the entity POJO after running the SELECT statement that loads the entity from the associated table

However, in your case, you didn't call either getOne or findById:

Person person = personRepository.findOne(1L);

So, I assume the findOne method is a method you defined in the PersonRepository. However, the findOne method is not very useful in your case. Since you need to fetch the Person along with is roles collection, it's better to use a findOneWithRoles method instead.

Custom Spring Data methods

You can define a PersonRepositoryCustom interface, as follows:

public interface PersonRepository
    extends JpaRepository<Person, Long>, PersonRepositoryCustom { 

}

public interface PersonRepositoryCustom {
    Person findOneWithRoles(Long id);
}

And define its implementation like this:

public class PersonRepositoryImpl implements PersonRepositoryCustom {

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public Person findOneWithRoles(Long id)() {
        return entityManager.createQuery("""
            select p 
            from Person p
            left join fetch p.roles
            where p.id = :id 
            """, Person.class)
        .setParameter("id", id)
        .getSingleResult();
    }
}

That's it!

For Bash, KornShell (ksh), sh, etc. Many of your questions are quickly answered by either:

man [function]

to get the documentation for the system you are using or usually more conveniently:

google "man function"

This may give different results for some things where Linux and Unix have modest differences.

For this question, just enter "whoami" in your shell.

To script it:

myvar=$(whoami)

1) Download winutils.exe from https://github.com/steveloughran/winutils 
2) Create a directory In windows "C:\winutils\bin
3) Copy the winutils.exe inside the above bib folder .
4) Set the environmental property in the code 
  System.setProperty("hadoop.home.dir", "file:///C:/winutils/");
5) Create a folder "file:///C:/temp" and give 777 permissions.
6) Add config property in spark Session ".config("spark.sql.warehouse.dir", "file:///C:/temp")"

Your syntax is fine, it will return rows where LastAdDate lies within the last 6 months;

select cast('01-jan-1970' as datetime) as LastAdDate into #PubAdvTransData 
    union select GETDATE()
    union select NULL
    union select '01-feb-2010'

DECLARE @sp_Date DATETIME = DateAdd(m, -6, GETDATE())

SELECT * FROM #PubAdvTransData pat
     WHERE (pat.LastAdDate > @sp_Date)

>2010-02-01 00:00:00.000
>2010-04-29 21:12:29.920

Are you sure LastAdDate is of type DATETIME?

yes, you can swap these 2 queries

select * from table limit 5, 5

select * from table limit 0, 5

KvanTTT's code worked great. I extended it a bit to allow a little more flexibility on save format, as well as the ability to save by hWnd, .NET Control/Form. You can get a bitmap or save to file, with a few options.

You can do all that by using just one RelativeLayout (which, btw, don't need android:orientation parameter). So, instead of having a LinearLayout, containing a bunch of stuff, you can do something like:

<RelativeLayout>
    <ImageButton
        android:layout_width="wrap_content"
        android:id="@+id/the_first_one"
        android:layout_alignParentLeft="true"/>
    <ImageButton
        android:layout_width="wrap_content"
        android:layout_toRightOf="@+id/the_first_one"/>
    <ImageButton
        android:layout_width="wrap_content"
        android:layout_alignParentRight="true"/>
</RelativeLayout>

As you noticed, there are some XML parameters missing. I was just showing the basic parameters you had to put. You can complete the rest.

I see that the question is too old, and hope my answer is helpful for others having the same issue...

I created a custom class MyButton extended from UIButton. Then added this inside the Identity Inspector:

After this, change the button type to Custom:

Then you can set attributes like textColor and UIFont for your UIButton for the different states:

Then I also created two methods inside MyButton class which I have to call inside my code when I want a UIButton to be displayed as highlighted:

- (void)changeColorAsUnselection{
    [self setTitleColor:[UIColor colorFromHexString:acColorGreyDark] 
               forState:UIControlStateNormal & 
                        UIControlStateSelected & 
                        UIControlStateHighlighted];
}

- (void)changeColorAsSelection{
    [self setTitleColor:[UIColor colorFromHexString:acColorYellow] 
               forState:UIControlStateNormal & 
                        UIControlStateHighlighted & 
                        UIControlStateSelected];
}

You have to set the titleColor for normal, highlight and selected UIControlState because there can be more than one state at a time according to the documentation of UIControlState. If you don't create these methods, the UIButton will display selection or highlighting but they won't stay in the UIColor you setup inside the UIInterface Builder because they are just available for a short display of a selection, not for displaying selection itself.

I encountered the same error.

In the end, the problem was that I used an image in res/drawable that I copied in there and saved it as .png although the original file was .jpg .

I deleted the file (there's a warning message if there are still usages for the item in your code, but you can ignore it) and pasted it in with the original .jpg ending.

After a cleanup and gradle syncronization the error disappeared.

Your guess is right: the code is trying to evaluate x**3+2*x-4 immediately. Unfortunately you can't really prevent it from doing so. The good news is that in Python, functions are first-class objects, by which I mean that you can treat them like any other variable. So to fix your function, we could do:

import numpy as np  
import matplotlib.pyplot as plt  

def graph(formula, x_range):  
    x = np.array(x_range)  
    y = formula(x)  # <- note now we're calling the function 'formula' with x
    plt.plot(x, y)  
    plt.show()  

def my_formula(x):
    return x**3+2*x-4

graph(my_formula, range(-10, 11))

If you wanted to do it all in one line, you could use what's called a lambda function, which is just a short function without a name where you don't use def or return:

graph(lambda x: x**3+2*x-4, range(-10, 11))

And instead of range, you can look at np.arange (which allows for non-integer increments), and np.linspace, which allows you to specify the start, stop, and the number of points to use.

ES6 now supports the startsWith() and endsWith() method for checking beginning and ending of strings. If you want to support pre-es6 engines, you might want to consider adding one of the suggested methods to the String prototype.

if (typeof String.prototype.startsWith != 'function') {
  String.prototype.startsWith = function (str) {
    return this.match(new RegExp("^" + str));
  };
}

if (typeof String.prototype.endsWith != 'function') {
  String.prototype.endsWith = function (str) {
    return this.match(new RegExp(str + "$"));
  };
}

var str = "foobar is not barfoo";
console.log(str.startsWith("foob"); // true
console.log(str.endsWith("rfoo");   // true

BitmapFactory.Options options=new BitmapFactory.Options();
            options.inSampleSize = 10;
            FixBitmap = BitmapFactory.decodeFile(ImagePath, options);
            //FixBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.gv);

           byteArrayOutputStream = new ByteArrayOutputStream();
           FixBitmap.compress(Bitmap.CompressFormat.JPEG, 80, byteArrayOutputStream); //compress to 50% of original image quality
           byteArray = byteArrayOutputStream.toByteArray();

           ConvertImage = Base64.encodeToString(byteArray, Base64.DEFAULT);

Having tried various approaches to move a file or folder from one Git repository to another, the only one which seems to work reliably is outlined below.

It involves cloning the repository you want to move the file or folder from, moving that file or folder to the root, rewriting Git history, cloning the target repository and pulling the file or folder with history directly into this target repository.

Stage One

1. Make a copy of repository A as the following steps make major changes to this copy which you should not push!

   git clone --branch <branch> --origin origin --progress \
     -v <git repository A url>
   # eg. git clone --branch master --origin origin --progress \
   #   -v https://username@giturl/scm/projects/myprojects.git
   # (assuming myprojects is the repository you want to copy from)
   

2. cd into it

   cd <git repository A directory>
   #  eg. cd /c/Working/GIT/myprojects
   

3. Delete the link to the original repository to avoid accidentally making any remote changes (eg. by pushing)

   git remote rm origin
   

4. Go through your history and files, removing anything that is not in directory 1. The result is the contents of directory 1 spewed out into to the base of repository A.

   git filter-branch --subdirectory-filter <directory> -- --all
   # eg. git filter-branch --subdirectory-filter subfolder1/subfolder2/FOLDER_TO_KEEP -- --all
   

5. For single file move only: go through what's left and remove everything except the desired file. (You may need to delete files you don't want with the same name and commit.)

   git filter-branch -f --index-filter \
   'git ls-files -s | grep $'\t'FILE_TO_KEEP$ |
   GIT_INDEX_FILE=$GIT_INDEX_FILE.new \
   git update-index --index-info && \
   mv $GIT_INDEX_FILE.new $GIT_INDEX_FILE || echo "Nothing to do"' --prune-empty -- --all
   # eg. FILE_TO_KEEP = pom.xml to keep only the pom.xml file from FOLDER_TO_KEEP
   

Stage Two

1. Cleanup step

   git reset --hard
   

2. Cleanup step

   git gc --aggressive
   

3. Cleanup step

   git prune
   

You may want to import these files into repository B within a directory not the root:

1. Make that directory

   mkdir <base directory>             eg. mkdir FOLDER_TO_KEEP
   

2. Move files into that directory

   git mv * <base directory>          eg. git mv * FOLDER_TO_KEEP
   

3. Add files to that directory

   git add .
   

4. Commit your changes and we’re ready to merge these files into the new repository

   git commit
   

Stage Three

1. Make a copy of repository B if you don’t have one already

   git clone <git repository B url>
   # eg. git clone https://username@giturl/scm/projects/FOLDER_TO_KEEP.git
   

   (assuming FOLDER_TO_KEEP is the name of the new repository you are copying to)

2. cd into it

   cd <git repository B directory>
   #  eg. cd /c/Working/GIT/FOLDER_TO_KEEP
   

3. Create a remote connection to repository A as a branch in repository B

   git remote add repo-A-branch <git repository A directory>
   # (repo-A-branch can be anything - it's just an arbitrary name)
   
   # eg. git remote add repo-A-branch /c/Working/GIT/myprojects
   

4. Pull from this branch (containing only the directory you want to move) into repository B.

   git pull repo-A-branch master --allow-unrelated-histories
   

   The pull copies both files and history. Note: You can use a merge instead of a pull, but pull works better.

5. Finally, you probably want to clean up a bit by removing the remote connection to repository A

   git remote rm repo-A-branch
   

6. Push and you’re all set.

   git push
   

I believe the 2GB limit is for 32-bit Java. I thought v1.6 was always 64 bit, but try forcing 64 bit mode just to see: add the -d64 option.

Steps I followed 1) Execute the command adb nodaemon server in command prompt Output at command prompt will be: The following error occurred cannot bind 'tcp:5037' The original ADB server port binding failed

2) Enter the following command query which using port 5037 netstat -ano | findstr "5037" The following information will be prompted on command prompt: TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 9288

3) View the task manager, close all adb.exe

4) Restart eclipse or other IDE

The above steps worked for me.

Here's the ready-made query for you:

SELECT

'drop table if exists "' || tablename || '" cascade;' as pg_drop

FROM

pg_tables

WHERE

schemaname='your schema';

In 2015 I would go with:

• For small scripts: The js editor + jsHint plugin
• For large code bases: TypeScript Eclipse plugin, or a similar transpiled language... I only know that TypeScript works well in Eclipse.

Of course you may want to keep JS for easy project setup and to avoid the transpilation process... there is no ultimate solution.

Or just wait for ECMA6, 7, ... :)

This answer is for the impatient/ have deadlines to meet to, only a part/simple explanation is below:

• in C++, you can have same name in class via overloading (for example, since they are all same name can't be exported as-is from dll, etc.) solution to these problems is they are converted to different strings (called symbols), symbols accounts the name of function, also the arguments, so each of these functions even with same name, can be uniquely identified (also called, name mangling)
• in C, you don't have overloading, the function name is unique (so, a separate string for identifying the a function name uniquely is not required, so symbol is function name itself)

So
in C++, with name mangling uniquely identities each function
in C, even without name mangling uniquely identities each function

To change the behaviour of C++, that is, to specify that name mangling should not happen for a particular function, you can use extern "C" before the function name, for whatever reason, like exporting a function with a specific name from a dll, for use by its clients.

Read other answers, for more detailed/more correct answers.

The biggest difference is their functionality. push_back always puts a new element at the end of the vector and insert allows you to select new element's position. This impacts the performance. vector elements are moved in the memory only when it's necessary to increase it's length because too little memory was allocated for it. On the other hand insert forces to move all elements after the selected position of a new element. You simply have to make a place for it. This is why insert might often be less efficient than push_back.

Short of using 12c overflow using the CLOB and substr will also work

rtrim(dbms_lob.substr(XMLAGG(XMLELEMENT(E,column_name,',').EXTRACT('//text()') ORDER BY column_name).GetClobVal(),1000,1),',')

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

Ultimately was able to figure it out , i just hope it will help someone like me.
Following is how the web pack config file should look like check the dist dir and output file specified. I was missing the way to specify the path of dist directory

const webpack = require('webpack');
const path = require('path');
var config = {
    entry: './main.js',

    output: {
        path: path.join(__dirname, '/dist'),
        filename: 'index.js',
    },

    devServer: {
        inline: true,
        port: 8080
    },
    resolveLoader: {
        modules: [path.join(__dirname, 'node_modules')]
    },
    module: {
        loaders: [
            {
                test: /\.jsx?$/,
                exclude: /node_modules/,
                loader: 'babel-loader',

                query: {
                    presets: ['es2015', 'react']
                }
            }
        ]
    },
}

module.exports = config;

Then the package json file

{
  "name": "reactapp",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack --progress",
    "production": "webpack -p --progress"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^15.4.2",
    "react-dom": "^15.4.2",
    "webpack": "^2.2.1"
  },
  "devDependencies": {
    "babel-core": "^6.0.20",
    "babel-loader": "^6.0.1",
    "babel-preset-es2015": "^6.0.15",
    "babel-preset-react": "^6.0.15",
    "babel-preset-stage-0": "^6.0.15",
    "express": "^4.13.3",
    "webpack": "^1.9.6",
    "webpack-devserver": "0.0.6"
  }
}

Notice the script section and production section, production section is what gives you the final deployable index.js file ( name can be anything )

Rest fot the things will depend upon your code and components

Execute following sequence of commands

npm install

this should get you all the dependency (node modules)

then

npm run production

this should get you the final index.js file which will contain all the code bundled

Once done place index.html and index.js files under www/html or the web app root directory and that's all.

TRY TO INSTALL 32BIT JDK

if you have jdk installed and had set up the System Varibles such as JAVA_HOME or JDK_HOME and tried click back and then next ,you might have installed the 64bit JDK,just download the 32bit jdk and install it.

They are both different. SelectedValue property gives you the actual value of the item in selection whereas SelectedItem.Text gives you the display text. For example: you drop down may have an itme like

<asp:ListItem Text="German" Value="de"></asp:ListItem>

So, in this case SelectedValue would be de and SelectedItem.Text would give 'German'

EDIT:

In that case, they aare both same ... Cause SelectedValue will give you the value stored for current selected item in your dropdown and SelectedItem.Value will be Value of the currently selected item.

So they both would give you the same result.

fd = fs.openSync(path.join(process.cwd(), 'log.txt'), 'a')
fs.writeSync(fd, 'contents to append')
fs.closeSync(fd)

You can use

git reset

to undo the recently added local files

 git reset file_name

to undo the changes for a specific file

This works for me:

String generateUniqueFileName() {
    String filename = "";
    long millis = System.currentTimeMillis();
    String datetime = new Date().toGMTString();
    datetime = datetime.replace(" ", "");
    datetime = datetime.replace(":", "");
    String rndchars = RandomStringUtils.randomAlphanumeric(16);
    filename = rndchars + "_" + datetime + "_" + millis;
    return filename;
}

// USE:

String newFile;
do{
newFile=generateUniqueFileName() + "." + FileExt;
}
while(new File(basePath+newFile).exists());

Output filenames should look like :

2OoBwH8OwYGKW2QE_4Sep2013061732GMT_1378275452253.Ext

As others have said, some email programs will not read the css styles. If you already have a web email written up you can use the following tool from zurb to inline all of your styles:

http://zurb.com/ink/inliner.php

This comes in extremely handy when using templates like those mentioned above from mailchimp, campaign monitor, etc. as they, as you have found, will not work in some email programs. This tool leaves your style section for the mail programs that will read it and puts all the styles inline to get more universal readability in the format that you wanted.

Try the following

1. download HAXM from Intel https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager.

2. Unzip the file and Run intelhaxm-android.exe.

3. Run silent_install.bat.

In my computer Win10 x64 - VS2015 it worked

the way most developers will do is:

<div id="web-title">
   <a href="http://website.com" title="Website" rel="home">
       <span class="webname">Website Name</span>
   </a>
</div>

.webname {
   display: none;
}

I used to do it too, until i realized that you are hiding content for devices. aka screen-readers and such.

So by passing:

#web-title span {text-indent: -9000em;}

you ensure that the text still is readable.

I'd go with @sandeep's display: table-cell answer if you don't care about IE7.

Otherwise, here's an alternative, with one downside: the "right" div has to come first in the HTML.

See: http://jsfiddle.net/thirtydot/qLTMf/
and exactly the same, but with the "right div" removed: http://jsfiddle.net/thirtydot/qLTMf/1/

#parent {
    overflow: hidden;
    border: 1px solid red
}
.right {
    float: right;
    width: 100px;
    height: 100px;
    background: #888;
}
.left {
    overflow: hidden;
    height: 100px;
    background: #ccc
}
<div id="parent">
    <div class="right">right</div>
    <div class="left">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam semper porta sem, at ultrices ante interdum at. Donec condimentum euismod consequat. Ut viverra lorem pretium nisi malesuada a vehicula urna aliquet. Proin at ante nec neque commodo bibendum. Cras bibendum egestas lacus, nec ullamcorper augue varius eget.</div>
</div>

I had the same issue until I added Response.Buffer = False. Try changing the code to the following.

Response.Buffer = False Response.ContentType = "application/vnd.ms-excel" Response.AddHeader "Content-Disposition", "attachment; filename=excelTest.xls"

The only problem I have now is that when Excel opens the file I get the following message.

The file you are trying to open, 'FileName[1].xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?

When you open the file the data all appears in separate columns, but the spreadsheet is all white, no borders between the cells.

Hope that helps.

$startinfo = new-object System.Diagnostics.ProcessStartInfo 
$startinfo.FileName = "explorer.exe"
$startinfo.WorkingDirectory = 'D:\foldername'

[System.Diagnostics.Process]::Start($startinfo)

Hope this helps

I don't think there would be any significant performance difference between them, but I would prefer the 1st way.

If you have a Boolean reference, Boolean.toString(boolean) will throw NullPointerException if your reference is null. As the reference is unboxed to boolean before being passed to the method.

While, String.valueOf() method as the source code shows, does the explicit null check:

public static String valueOf(Object obj) {
    return (obj == null) ? "null" : obj.toString();
}

Just test this code:

Boolean b = null;

System.out.println(String.valueOf(b));    // Prints null
System.out.println(Boolean.toString(b));  // Throws NPE

For primitive boolean, there is no difference.

For me the better solution was the following. Since the initiative of closing the connection was done by the server, the setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) had no effect and the TIME_WAIT was avoiding a new connection on the same port with error:

[Errno 10048]: Address already in use. Only one usage of each socket address (protocol/IP address/port) is normally permitted 

I finally used the solution to let the OS choose the port itself, then another port is used if the precedent is still in TIME_WAIT.

I replaced:

self._socket.bind((guest, port))

with:

self._socket.bind((guest, 0))

As it was indicated in the python socket documentation of a tcp address:

If supplied, source_address must be a 2-tuple (host, port) for the socket to bind to as its source address before connecting. If host or port are ‘’ or 0 respectively the OS default behavior will be used.

I'f you're suppsed to be able to use it, then 3rd-party library should have a *.lib file as well as a *.dll file. You simply need to add the *.lib to the list of input file in your project's 'Linker' options.

This *.lib file isn't necessarily a 'static' library (which contains code): instead a *.lib can be just a file that links your executable to the DLL.

The first thing to do would probably be to replace every mysql_* function call with its equivalent mysqli_*, at least if you are willing to use the procedural API -- which would be the easier way, considering you already have some code based on the MySQL API, which is a procedural one.

To help with that, the MySQLi Extension Function Summary is definitely something that will prove helpful.

For instance:

• mysql_connect will be replaced by mysqli_connect
• mysql_error will be replaced by mysqli_error and/or mysqli_connect_error, depending on the context
• mysql_query will be replaced by mysqli_query
• and so on

Note: For some functions, you may need to check the parameters carefully: Maybe there are some differences here and there -- but not that many, I'd say: both mysql and mysqli are based on the same library (libmysql ; at least for PHP <= 5.2)

For instance:

• with mysql, you have to use the mysql_select_db once connected, to indicate on which database you want to do your queries
• mysqli, on the other side, allows you to specify that database name as the fourth parameter to mysqli_connect.
• Still, there is also a mysqli_select_db function that you can use, if you prefer.

A much simpler way to do this is to use split():

String match = "123woods";
String text = "I will come and meet you at the 123woods";

String[] sentence = text.split();
for(String word: sentence)
{
    if(word.equals(match))
        return true;
}
return false;

This is a simpler, less elegant way to do the same thing without using tokens, etc.

I gather the documentation wasn't great back in 2012 when this question was asked, but for anyone reading this in 2020+: There's now a whole section in the docs about how to add a source set for integration tests. You really should read it instead of copy/pasting code snippets here and banging your head against the wall trying to figure out why an answer from 2012-2016 doesn't quite work.

The answer is most likely simple but more nuanced than you may think, and the exact code you'll need is likely to be different from the code I'll need. For example, do you want your integration tests to use the same dependencies as your unit tests?

It's a quote issue, you need :

projectID=$(
  cat file.json | jq -r ".resource[] | select(.username=='$EMAILID') | .id"
)

If you put single quotes to delimit the main string, the shell takes $EMAILID literally.

"Double quote" every literal that contains spaces/metacharacters and every expansion: "$var", "$(command "$var")", "${array[@]}", "a & b". Use 'single quotes' for code or literal $'s: 'Costs $5 US', ssh host 'echo "$HOSTNAME"'. See
http://mywiki.wooledge.org/Quotes

The only way to remove the dotted line (to my knowledge) is with css hacking using plugin.

• Install the User CSS (or User JS & CSS) plugin, which allows adding CSS rules per site.

• Once on Google Docs, click the plugins icon, toggle the OFF to ON button, and add the following css code:

.

.kix-page-compact::before{
    border-top: none;
}

Should work like a charm.

You can also just simply do the regular apt-get update and then, as per the manual, do:

apt-get -V upgrade

-V Show verbose version numbers

Which will show you the current package vs the one which will be upgraded in a format similar to the one bellow:

~# sudo apt-get -V upgrade
Reading package lists... Done

Short ES6 code

const convertFrom24To12Format = (time24) => {
  const [sHours, minutes] = time24.match(/([0-9]{1,2}):([0-9]{2})/).slice(1);
  const period = +sHours < 12 ? 'AM' : 'PM';
  const hours = +sHours % 12 || 12;

  return `${hours}:${minutes} ${period}`;
}

const convertFrom12To24Format = (time12) => {
  const [sHours, minutes, period] = time12.match(/([0-9]{1,2}):([0-9]{2}) (AM|PM)/).slice(1);
  const PM = period === 'PM';
  const hours = (+sHours % 12) + (PM ? 12 : 0);

  return `${('0' + hours).slice(-2)}:${minutes}`;
}

Try this:

 moment("02/26/1978", "MM/DD/YYYY").fromNow().split(" ")[0];

Explanation:

We receive string something like this: '23 days ago'. Split it to array: ['23', 'days', 'ago'] and then take first item '23'.

For Swift 2.X and above

button.addTarget(self,action:#selector(YourControllerName.buttonClicked(_:)),
                         forControlEvents:.TouchUpInside)

Simply use this method.

<?php
    $_SESSION['foo'] = 'bar'; // set session 
    print $_SESSION['foo']; //print it
    unset($_SESSION['foo']); //unset session 
?>

There is no way in Selenium to read the request or response headers. You could do it by instructing your browser to connect through a proxy that records this kind of information.

Setting the User Agent in Firefox

The usual way to change the user agent for Firefox is to set the variable "general.useragent.override" in your Firefox profile. Note that this is independent from Selenium.

You can direct Selenium to use a profile different from the default one, like this:

from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", "whatever you want")
driver = webdriver.Firefox(profile)

Setting the User Agent in Chrome

With Chrome, what you want to do is use the user-agent command line option. Again, this is not a Selenium thing. You can invoke Chrome at the command line with chrome --user-agent=foo to set the agent to the value foo.

With Selenium you set it like this:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
opts = Options()
opts.add_argument("user-agent=whatever you want")

driver = webdriver.Chrome(chrome_options=opts)

Both methods above were tested and found to work. I don't know about other browsers.

Getting the User Agent

Selenium does not have methods to query the user agent from an instance of WebDriver. Even in the case of Firefox, you cannot discover the default user agent by checking what general.useragent.override would be if not set to a custom value. (This setting does not exist before it is set to some value.)

Once the browser is started, however, you can get the user agent by executing:

agent = driver.execute_script("return navigator.userAgent")

The agent variable will contain the user agent.

There was a recent blog post: https://medium.com/@vgasparyan1995/pass-by-value-vs-pass-by-reference-to-const-c-f8944171e3ce

So the answer to this is: Do (almost) never pass by const shared_ptr<T>&.
Simply pass the underlying class instead.

Basically the only reasonable parameters types are:

• shared_ptr<T> - Modify and take ownership
• shared_ptr<const T> - Don't modify, take ownership
• T& - Modify, no ownership
• const T& - Don't modify, no ownership
• T - Don't modify, no ownership, Cheap to copy

As @accel pointed out in https://stackoverflow.com/a/26197326/1930508 the advice from Herb Sutter is:

Use a const shared_ptr& as a parameter only if you’re not sure whether or not you’ll take a copy and share ownership

But in how many cases are you not sure? So this is a rare situation

this solution it gonna be ok on Redhat 8.0

sudo yum install libxml2-devel

Seems like just this works:

curl -I http://example.com

Look for Access-Control-Allow-Origin: * in the returned headers

While almost everyone over here has given the correct answer, no body explained on what basis are the Alarms work

You can actually learn more about AlarmManager and its working here . But here is the quick answer

You see AlarmManager basically schedules a PendingIntent at some time in future. So in order to cancel the scheduled Alarm you need to cancel the PendingIntent.

Always keep note of two things while creating the PendingIntent

PendingIntent.getBroadcast(context,REQUEST_CODE,intent, PendingIntent.FLAG_UPDATE_CURRENT);

• Request Code - Acts as the unique identifier
• Flag - Defines the behavior of PendingIntent

Now to check if the Alarm is already scheduled or to cancel the Alarm you just need to get access to the same PendingIntent. This can be done if you use same request code and use FLAG_NO_CREATE like shown below

PendingIntent pendingIntent=PendingIntent.getBroadcast(this,REQUEST_CODE,intent,PendingIntent.FLAG_NO_CREATE);

if (pendingIntent!=null)
   alarmManager.cancel(pendingIntent);

With FLAG_NO_CREATE it will return null if the PendingIntent doesn't already exist. If it already exists it returns reference to the existing PendingIntent

Let's see how to get and print day,month,year in python from current time:

import datetime

now = datetime.datetime.now()
year = '{:02d}'.format(now.year)
month = '{:02d}'.format(now.month)
day = '{:02d}'.format(now.day)
hour = '{:02d}'.format(now.hour)
minute = '{:02d}'.format(now.minute)
day_month_year = '{}-{}-{}'.format(year, month, day)

print('day_month_year: ' + day_month_year)

result:

day_month_year: 2019-03-26

Yes the example by nixlike works very well.

The code you posted will work; it will print out all the members of the enum, including the values of the enum members. For example, the following code:

enum myEnum { bar, foo }

for (var enumMember in myEnum) {
   console.log("enum member: ", enumMember);
}

Will print the following:

Enum member: 0
Enum member: 1
Enum member: bar
Enum member: foo

If you instead want only the member names, and not the values, you could do something like this:

for (var enumMember in myEnum) {
   var isValueProperty = parseInt(enumMember, 10) >= 0
   if (isValueProperty) {
      console.log("enum member: ", myEnum[enumMember]);
   }
}

That will print out just the names:

Enum member: bar  
Enum member: foo

Caveat: this slightly relies on an implementation detail: TypeScript compiles enums to a JS object with the enum values being members of the object. If TS decided to implement them different in the future, the above technique could break.

Run eventvwr from the command line to see if it has recorded any Application errors.

This might give you an actual error message that is more useful.

Ctrl+C terminates the main thread, but because your threads aren't in daemon mode, they keep running, and that keeps the process alive. We can make them daemons:

f = FirstThread()
f.daemon = True
f.start()
s = SecondThread()
s.daemon = True
s.start()

But then there's another problem - once the main thread has started your threads, there's nothing else for it to do. So it exits, and the threads are destroyed instantly. So let's keep the main thread alive:

import time
while True:
    time.sleep(1)

Now it will keep print 'first' and 'second' until you hit Ctrl+C.

Edit: as commenters have pointed out, the daemon threads may not get a chance to clean up things like temporary files. If you need that, then catch the KeyboardInterrupt on the main thread and have it co-ordinate cleanup and shutdown. But in many cases, letting daemon threads die suddenly is probably good enough.

There is a property called all in the CSS3 inheritance module. It works like this:

#sidebar ul li {
  all: initial;
}

As of 2016-12, all browsers but IE/Edge and Opera Mini support this property.

You can try this.. My own version of it..

funcc() {
while true ; do 
for i in \| \/ \- \\ \| \/ \- \\; do 
  echo -n -e "\r$1  $i  "
sleep 0.5
done  
#echo -e "\r                                                                                      "
[ -f /tmp/print-stat ] && break 2
done
}

funcc "Checking Kubectl" & &>/dev/null
sleep 5
touch /tmp/print-stat
echo -e "\rPrint Success                  "

I simplification for Science_Fiction's answer I think is to use the exclusive or function so you can just have:

if(checkbox1.checked ^ checkbox2.checked)
{
//do stuff
}

That is assuming you want to do the same thing for both situations.

Here i am binding the gridview with dataset like this-

GVAnswer.DataSource = DS.Tables[0];
GVAnswer.DataBind();

Then after

Then we count the number of rows like this in the for loop

for (int i = 0; i < GVAnswer.Rows.Count; i++)
{

}

Then after we find the header we want make visible false

GVAnswer.HeaderRow.Cells[2].Visible = false;

then after we make the visibility false of that particular cell.

When you need padding inside the JPanel generally you add padding with the layout manager you are using. There are cases that you can just expand the border of the JPanel.

The best I can find is to set input[type="password"] {font:small-caption;font-size:16px}

We recently released a library that helps a lot to access private fields, methods and inner classes through reflection : BoundBox

For a class like

public class Outer {
    private static class Inner {
        private int foo() {return 2;}
    }
}

It provides a syntax like :

Outer outer = new Outer();
Object inner = BoundBoxOfOuter.boundBox_new_Inner();
new BoundBoxOfOuter.BoundBoxOfInner(inner).foo();

The only thing you have to do to create the BoundBox class is to write @BoundBox(boundClass=Outer.class) and the BoundBoxOfOuter class will be instantly generated.

This is actually possible since Facebook was able to do it. Well, not the actual web developer tools but the execution of Javascript in console.

See this: How does Facebook disable the browser's integrated Developer Tools?

This really wont do much though since there are other ways to bypass this type of client-side security.

When you say it is client-side, it happens outside the control of the server, so there is not much you can do about it. If you are asking why Facebook still does this, this is not really for security but to protect normal users that do not know javascript from running code (that they don't know how to read) into the console. This is common for sites that promise auto-liker service or other Facebook functionality bots after you do what they ask you to do, where in most cases, they give you a snip of javascript to run in console.

If you don't have as much users as Facebook, then I don't think there's any need to do what Facebook is doing.

Even if you disable Javascript in console, running javascript via address bar is still possible.

and if the browser disables javascript at address bar, (When you paste code to the address bar in Google Chrome, it deletes the phrase 'javascript:') pasting javascript into one of the links via inspect element is still possible.

Inspect the anchor:

Paste code in href:

Bottom line is server-side validation and security should be first, then do client-side after.

One way of doing that would be having a separate service that can be used as a 'vessel' for those arguments where they're public data members.

Another idea, indeed more a dirty hack, regarding mod rewrite is server dependend an not necessary a php issue: Why not, if you have the possibillity, create a test directory put a .htaccess in it rewriting to test.php, call the directory via http and check if you get the expected result you put in test.php.

Indeed, dirty.

I followed below steps for resolution for this issue in Windows 10:

1. First make sure you have installed Angular CLI . You can use below to install same.

npm install -g @angular/cli@latest

2. Make sure that AppData is visible and navigate to path below.

C:\Users\rkota\AppData\Roaming\npm

Same path can be found by running below too:

npm config get prefix

3. Add the above path i.e. " C:\Users\rkota\AppData\Roaming\npm" in Environment variable PATH and make sure it got added by running path in command prompt.
4. Close command prompt and now try to run below:

ng --version

you will be able to see CLI version.

This error happen usually when tables in the query doesn't exist. Just check the table's spelling in the query, and it will work.

I may have not got your answer correct, but you can try this:

public void MusicController(View view) throws IOException{
    switch (view.getId()){
        case R.id.play: mplayer.start();break;
        case R.id.pause: mplayer.pause(); break;
        case R.id.stop:
            if(mplayer.isPlaying()) {
                mplayer.stop();
                mplayer.prepare(); 
            }
            break;

    }// where mplayer is defined in  onCreate method}

as there is just one thread handling all, so stop() makes it die so we have to again prepare it If your intent is to start it again when your press start button(it throws IO Exception) Or for better understanding of MediaPlayer you can refer to Android Media Player

Use IS instead of = This will solve your problem example syntax:

UPDATE studentdetails
SET contactnumber = 9098979690
WHERE contactnumber IS NULL;

Use res.download()

It transfers the file at path as an “attachment”. For instance:

var express = require('express');
var router = express.Router();

// ...

router.get('/:id/download', function (req, res, next) {
    var filePath = "/my/file/path/..."; // Or format the path using the `id` rest param
    var fileName = "report.pdf"; // The default name the browser will use

    res.download(filePath, fileName);    
});

• Read more about res.download()

You need to apply the following CSS property to the container block (div):

overflow-wrap: break-word;

According to the specifications (source CSS | MDN):

The overflow-wrap CSS property specifies whether or not the browser should insert line breaks within words to prevent text from overflowing its content box.

With the value set to break-word

To prevent overflow, normally unbreakable words may be broken at arbitrary points if there are no otherwise acceptable break points in the line.

Worth mentioning...

The property was originally a nonstandard and unprefixed Microsoft extension called word-wrap, and was implemented by most browsers with the same name. It has since been renamed to overflow-wrap, with word-wrap being an alias.

If you care about legacy browsers support it's worth specifying both:

word-wrap    : break-word;
overflow-wrap: break-word;

Ex. IE9 does not recognize overflow-wrap but works fine with word-wrap

Python datetime objects don't have time zone info by default, and without it, Python actually violates the ISO 8601 specification (if no time zone info is given, assumed to be local time). You can use the pytz package to get some default time zones, or directly subclass tzinfo yourself:

from datetime import datetime, tzinfo, timedelta
class simple_utc(tzinfo):
    def tzname(self,**kwargs):
        return "UTC"
    def utcoffset(self, dt):
        return timedelta(0)

Then you can manually add the time zone info to utcnow():

>>> datetime.utcnow().replace(tzinfo=simple_utc()).isoformat()
'2014-05-16T22:51:53.015001+00:00'

Note that this DOES conform to the ISO 8601 format, which allows for either Z or +00:00 as the suffix for UTC. Note that the latter actually conforms to the standard better, with how time zones are represented in general (UTC is a special case.)

subprocess.Popen takes a list of arguments:

from subprocess import Popen, PIPE

process = Popen(['swfdump', '/tmp/filename.swf', '-d'], stdout=PIPE, stderr=PIPE)
stdout, stderr = process.communicate()

There's even a section of the documentation devoted to helping users migrate from os.popen to subprocess.

Another extension method to work around this:

public static void ForEach<T>(this IEnumerable<T> items, Action<T> action)
{
    if(items == null) return;
    foreach (var item in items) action(item);
}

Consume in several ways:

(1) with a method that accepts T:

returnArray.ForEach(Console.WriteLine);

(2) with an expression:

returnArray.ForEach(i => UpdateStatus(string.Format("{0}% complete", i)));

(3) with a multiline anonymous method

int toCompare = 10;
returnArray.ForEach(i =>
{
    var thisInt = i;
    var next = i++;
    if(next > 10) Console.WriteLine("Match: {0}", i);
});

Add div wrapper

<div id=myForm>
<select name=countries>
 <option value=af>Afghanistan</option>
 <option value=ax>Åland Islands</option>
 ...
 <option value=gs>South Georgia and the South Sandwich Islands</option>
 ...
</select>
</div>

and then write CSS

#myForm select { 
width:200px; }

#myForm select:focus {
width:auto; }

Hope this will help.

For some reason, the above answer did not work for me; I did not return to the command prompt after running it as I expected with the trailing &. Instead, I simply tried with

nohup some_command > nohup2.out&

and it works just as I want it to. Leaving this here in case someone else is in the same situation. Running Bash 4.3.8 for reference.

I had a similar problem...and my issue was related to using too high of an sdk....

I changed:

uses-sdk android:minSdkVersion="17" android:targetSdkVersion="17"/

to

uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17"

and my problem was solved.

You can use the six library to support both Python 2 and 3:

import six
if isinstance(value, six.string_types):
    handle_string(value)

Let the problem be: finding the Kth largest element in an unsorted array.

Divide the array into n/5 groups where each group consisting of 5 elements.

Now a1,a2,a3....a(n/5) represent the medians of each group.

x = Median of the elements a1,a2,.....a(n/5).

Now if k<n/2 then we can remove the largets, 2nd largest and 3rd largest element of the groups whose median is greater than the x. We can now call the function again with 7n/10 elements and finding the kth largest value.

else if k>n/2 then we can remove the smallest ,2nd smallest and 3rd smallest element of the group whose median is smaller than the x. We can now call the function of again with 7n/10 elements and finding the (k-3n/10)th largest value.

Time Complexity Analysis: T(n) time complexity to find the kth largest in an array of size n.

T(n) = T(n/5) + T(7n/10) + O(n)

if you solve this you will find out that T(n) is actually O(n)

n/5 + 7n/10 = 9n/10 < n

You can look at the Columns property of a given DataTable, it is a list of all columns in the table.

private void PrintValues(DataTable table)
{
    foreach(DataRow row in table.Rows)
    {
        foreach(DataColumn column in table.Columns)
        {
            Console.WriteLine(row[column]);
        }
    }
}

http://msdn.microsoft.com/en-us/library/system.data.datatable.columns.aspx

Try This,

public View getView(final int position, View convertView,ViewGroup parent) 
{
   if(convertView == null)
   {
        LayoutInflater inflater = getLayoutInflater();
        convertView  = (LinearLayout)inflater.inflate(R.layout.YOUR_LAYOUT, null);
   }

   Button Button1= (Button)  convertView  .findViewById(R.id.BUTTON1_ID);

   Button1.setOnClickListener(new OnClickListener() 
   { 
       @Override
       public void onClick(View v) 
       {
           // Your code that you want to execute on this button click
       }

   });


   return convertView ;
}

It may help you....

My 2 cents contribution:

Besides removing the console warning (as shown above), it's best to remove yours logs from PROD environments (for security reasons). The best way I found to do so, is by adding this to nuxt.config.js

  build: {
   terser: {
      terserOptions: {
        compress: {
          //this removes console.log from production environment
          drop_console: true
        }
      }
    }
  }

How it works: Nuxt already uses terser as minifier. This config will force terser to ignore/remove all console logs commands during compression.

I would say store them as an big integer, as a phone number itself is just a number. This also gives you more flexibility in how you present your phone numbers later, depending on what situation you are in.

Find the latest version of chromedriver here. Once downloaded, unzip it at the root of your Python installation, e.g., C:/Program Files/Python-3.5, and that's it.

You don't even need to specify the path anywhere and/or add chromedriver to your path or the like. I just did it on a clean Python installation and that works.

Just for the shake of completing the answer given by eipi10.

I was facing the same problem, without using scale_y_continuous nor coord_cartesian.

The conflict was coming from the x axis, where I defined limits = c(1, 30). It seems such limits do not provide enough space if you want to "dodge" your bars, so R still throws the error

Removed 8 rows containing missing values (geom_bar)

Adjusting the limits of the x axis to limits = c(0, 31) solved the problem.

In conclusion, even if you are not putting limits to your y axis, check out your x axis' behavior to ensure you have enough space

Use

Console.WriteLine(String.Format("  {0:G17}", i));

That will give you all the 17 digits it have. By default, a Double value contains 15 decimal digits of precision, although a maximum of 17 digits is maintained internally. {0:R} will not always give you 17 digits, it will give 15 if the number can be represented with that precision.

which returns 15 digits if the number can be represented with that precision or 17 digits if the number can only be represented with maximum precision. There isn't any thing you can to do to make the the double return more digits that is the way it's implemented. If you don't like it do a new double class yourself...

.NET's double cant store any more digits than 17 so you cant see 6.89999999999999946709 in the debugger you would see 6.8999999999999995. Please provide an image to prove us wrong.

With the new Substring type usage:

Swift 4:

var before: String = "Hello world!"
var lastCharIndex: Int = before.endIndex
var after:String = String(before[..<lastCharIndex])
print(after) // Hello world

Shorter way:

var before: String = "Hello world!"
after = String(before[..<before.endIndex])
print(after) // Hello world

Include <%@ page isELIgnored="false"%> on top of your jsp page.

Check the properties of App.xaml. Is the Build Action still ApplicationDefinition?

You should never use == for string comparison. === is OK.

$something = 0;
echo ('password123' == $something) ? 'true' : 'false';

Just run the above code and you'll see why.

$something = 0;
echo ('password123' === $something) ? 'true' : 'false';

Now, that's a little better.

Try /[^;]*/

Google regex character classes for details.

You can use tools own browser (Firefox, IE, Chrome...) to debug your JavaScript.

As for resizing, Firefox/Chrome has own resources accessible via Ctrl + Shift + I OR F12. Going tab "style editor" and clicking "adaptive/responsive design" icon.

*Another way is to install an addon like "Web Developer"

I had the same problem with my IntelliJ Maven build. My "solution" was to go into the build tools and remove the build tools 24.0.0 folder. I found it in the {android-sdk-location}/build-tools/ directory. This is not a long term fix, but this should at least get your project building again. Upgrading to Java 8 as many have suggested will be better long term.

I also had need for this and I created the following extension method for it:

public static class RegexExtensions
{
    public static string ReplaceGroup(
        this Regex regex, string input, string groupName, string replacement)
    {
        return regex.Replace(
            input,
            m =>
            {
                var group = m.Groups[groupName];
                var sb = new StringBuilder();
                var previousCaptureEnd = 0;
                foreach (var capture in group.Captures.Cast<Capture>())
                {
                    var currentCaptureEnd =
                        capture.Index + capture.Length - m.Index;
                    var currentCaptureLength =
                        capture.Index - m.Index - previousCaptureEnd;
                    sb.Append(
                        m.Value.Substring(
                            previousCaptureEnd, currentCaptureLength));
                    sb.Append(replacement);
                    previousCaptureEnd = currentCaptureEnd;
                }
                sb.Append(m.Value.Substring(previousCaptureEnd));

                return sb.ToString();
            });
    }
}

Usage:

var input = @"[assembly: AssemblyFileVersion(""2.0.3.0"")][assembly: AssemblyFileVersion(""2.0.3.0"")]";
var regex = new Regex(@"AssemblyFileVersion\(""(?<version>(\d+\.?){4})""\)");


var result = regex.ReplaceGroup(input , "version", "1.2.3");

Result:

[assembly: AssemblyFileVersion("1.2.3")][assembly: AssemblyFileVersion("1.2.3")]

In general, to make sure something happens no matter what, you use

from exceptions import NameError

try:
    f = open(x)
except ErrorType as e:
    pass # handle the error
finally:
    try:
        f.close()
    except NameError: pass

finally blocks will be run whether or not there is an error in the try block, and whether or not there is an error in any error handling that takes place in except blocks. If you don't handle an exception that is raised, it will still be raised after the finally block is excecuted.

The general way to make sure a file is closed is to use a "context manager".

http://docs.python.org/reference/datamodel.html#context-managers

with open(x) as f:
    # do stuff

This will automatically close f.

For your question #2, bar gets closed on immediately when it's reference count reaches zero, so on del foo if there are no other references.

Objects are NOT created by __init__, they're created by __new__.

http://docs.python.org/reference/datamodel.html#object.new

When you do foo = Foo() two things are actually happening, first a new object is being created, __new__, then it is being initialized, __init__. So there is no way you could possibly call del foo before both those steps have taken place. However, if there is an error in __init__, __del__ will still be called because the object was actually already created in __new__.

Edit: Corrected when deletion happens if a reference count decreases to zero.

Using just try_files didn't work for me - it caused a rewrite or internal redirection cycle error in my logs.

The Nginx docs had some additional details:

http://nginx.org/en/docs/http/ngx_http_core_module.html#try_files

So I ended up using the following:

root /var/www/mysite;

location / {
    try_files $uri /base.html;
}

location = /base.html {
    expires 30s;
}

There is a new option called validateStatus in request config. You can use it to specify to not throw exceptions if status < 100 or status > 300 (default behavior). Example:

const {status} = axios.get('foo.com', {validateStatus: () => true})

In my case (Windows XP + Apache2.2 + PHP 5.4.31) I changed PHPIniDir in the httpd.conf to get around this problem:

from:

"C:\php5\" 

to:

"C:/php5/"

git checkout {branch-name} -- {file-name}

This will use the file from the branch of choice.

I like this because posh-git autocomplete works great with this. It also removes any ambiguity as to which branch is remote and which is local. And --theirs didn't work for me anyways.

if you have the file inside a dirrectory called uploads in your project. bellow code can be used.

Path root = Paths.get("uploads");
File existingFile = new File(this.root.resolve("img.png").toUri());

if (existingFile.exists() && existingFile.isFile()) {
     existingFile.delete();
   }

OR

If it is inside a different directory this solution can be used.

File existingFile = new File("D:\\<path>\\img.png");

if (existingFile.exists() && existingFile.isFile()) {
    existingFile.delete();
  }

See .offset() here in the jQuery doc. It gives the position relative to the document, not to the parent. You perhaps have .offset() and .position() confused. If you want the position in the window instead of the position in the document, you can subtract off the .scrollTop() and .scrollLeft() values to account for the scrolled position.

Here's an excerpt from the doc:

The .offset() method allows us to retrieve the current position of an element relative to the document. Contrast this with .position(), which retrieves the current position relative to the offset parent. When positioning a new element on top of an existing one for global manipulation (in particular, for implementing drag-and-drop), .offset() is the more useful.

To combine these:

var offset = $("selector").offset();
var posY = offset.top - $(window).scrollTop();
var posX = offset.left - $(window).scrollLeft(); 

You can try it here (scroll to see the numbers change): http://jsfiddle.net/jfriend00/hxRPQ/

If your destination element is empty and will only contain the <svg> tag you could consider using ng-bind-html as follow :

Declare your HTML tag in the directive scope variable

link: function (scope, iElement, iAttrs) {

    scope.svgTag = '<svg width="600" height="100" class="svg"></svg>';

    ...
}

Then, in your directive template, just add the proper attribute at the exact place you want to append the svg tag :

<!-- start of directive template code -->
...
<!-- end of directive template code -->
<div ng-bind-html="svgTag"></div>

Don't forget to include ngSanitize to allow ng-bind-html to automatically parse the HTML string to trusted HTML and avoid insecure code injection warnings.

See official documentation for more details.

all of the answers above are too complexicated i would just change the variables by 0.1 instead of 1 this makes the ship 10 times slower if that is still too fast change the variables by 0.01 this makes the ship 100 times slower try this

keys=pygame.key.get_pressed()
if keys[K_LEFT]:
    location -= 0.1 #or 0.01
    if location==-1:
    location=0
if keys[K_RIGHT]:
    location += 0.1 #or 0.01
    if location==5:
        location=4

As many have stated more or less correctly what reference and primitive types are, one might be interested that we have some more relevant types in Java. Here is the complete lists of types in java (as far as I am aware of (JDK 11)).

Primitive Type

Describes a value (and not a type).

11

Reference Type

Describes a concrete type which instances extend Object (interface, class, enum, array). Furthermore TypeParameter is actually a reference type!

Integer

Note: The difference between primitive and reference type makes it necessary to rely on boxing to convert primitives in Object instances and vise versa.

Note2: A type parameter describes a type having an optional lower or upper bound and can be referenced by name within its context (in contrast to the wild card type). A type parameter typically can be applied to parameterized types (classes/interfaces) and methods. The parameter type defines a type identifier.

Wildcard Type

Expresses an unknown type (like any in TypeScript) that can have a lower or upper bound by using super or extend.

? extends List<String>
? super ArrayList<String>

Void Type

Nothingness. No value/instance possible.

void method();

Null Type

The only representation is 'null'. It is used especially during type interference computations. Null is a special case logically belonging to any type (can be assigned to any variable of any type) but is actual not considered an instance of any type (e.g. (null instanceof Object) == false).

null

Union Type

A union type is a type that is actual a set of alternative types. Sadly in Java it only exists for the multi catch statement.

catch(IllegalStateException | IOException e) {}

Interference Type

A type that is compatibile to multiple types. Since in Java a class has at most one super class (Object has none), interference types allow only the first type to be a class and every other type must be an interface type.

void method(List<? extends List<?> & Comparable> comparableList) {}

Unknown Type

The type is unknown. That is the case for certain Lambda definitions (not enclosed in brackets, single parameter).

list.forEach(element -> System.out.println(element.toString)); //element is of unknown type

Var Type

Unknown type introduced by a variable declaration spotting the 'var' keyword.

var variable = list.get(0);

This hasn't solved my problem too, so I changed the parameters slightly.
This code worked for me:

var dataValue = "{ name: 'person', isGoing: 'true', returnAddress: 'returnEmail' }";

$.ajax({
    type: "POST",
    url: "Default.aspx/OnSubmit",
    data: dataValue,
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    error: function (XMLHttpRequest, textStatus, errorThrown) {
        alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
    },
    success: function (result) {
        alert("We returned: " + result.d);
    }
});

Yep that sounds right to me. The design is what you're going to do, and architecture is the way in which the bits and pieces of the design will be joined together. It could be language agnostic, but would normally specify the technologies to be used ie LAMP v Windows, Web Service v RPC.

If you are using RemoteDriver things are different. From http://element34.ca/blog/iedriverserver-webdriver-and-python :

You will need to start the server using a line like

java -jar selenium-server-standalone-2.26.0.jar -Dwebdriver.ie.driver=C:\Temp\IEDriverServer.exe

I found that if the IEDriverServer.exe was in C:\Windows\System32\ or its subfolders, it couldn't be found automatically (even though System32 was in the %PATH%) or explicitly using the -D flag.

Following up to @steven-anderson you can also configure passwords inside the ant.properties, so the process can be fully automated

so if you put in platform\android\ant.properties the following

key.store=../../yourCertificate.jks
key.store.password=notSoSecretPassword
key.alias=userAlias
key.alias.password=notSoSecretPassword

Add comments for two different columns of the EMPLOYEE table :

COMMENT ON EMPLOYEE
     (WORKDEPT IS 'see DEPARTMENT table for names',
     EDLEVEL IS 'highest grade level passed in school' )

Quite an intuitive error message - just need to give the columns in d names

Change to either this

d as 
 (
  select                 
     [duration] = month(clothdeliverydate),                 
     [bkdqty] = SUM(CONVERT(INT, deliveredqty))             
  FROM                 
     barcodetable            
  where                 
     month(clothdeliverydate) is not null                
  group by month(clothdeliverydate)           
 ) 

Or you can explicitly declare the fields in the definition of the cte:

d ([duration], [bkdqty]) as 
 (
  select                 
     month(clothdeliverydate),                 
     SUM(CONVERT(INT, deliveredqty))             
  FROM                 
     barcodetable            
  where                 
     month(clothdeliverydate) is not null                
  group by month(clothdeliverydate)           
 )

It is in French, but you can understand everything! I solved same problem, even don't speak French. :-)

Many answers forget to mention that you need to add new version of php_curl.dll file from this location: http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

I added new version of php_curl.dll from archive php_curl-5.4.3-VC9-x64.zip to folders: C:\wamp\bin\php\php5.4.3\ext and C:\Windows\System32 and everything was fine!

You can get NaN from "inf - inf", and you can get "inf" from a number greater than 2e308, so, I generally used:

>>> inf = 9e999
>>> inf
inf
>>> inf - inf
nan

import numpy as np
import PIL

def convert_image(image_file):
    image = Image.open(image_file) # this could be a 4D array PNG (RGBA)
    original_width, original_height = image.size

    np_image = np.array(image)
    new_image = np.zeros((np_image.shape[0], np_image.shape[1], 3)) 
    # create 3D array

    for each_channel in range(3):
        new_image[:,:,each_channel] = np_image[:,:,each_channel]  
        # only copy first 3 channels.

    # flushing
    np_image = []
    return new_image

Two points not otherwise mentioned here that I find significant:

1) cout carries a lot of baggage if you're not already using the STL. It adds over twice as much code to your object file as printf. This is also true for string, and this is the major reason I tend to use my own string library.

2) cout uses overloaded << operators, which I find unfortunate. This can add confusion if you're also using the << operator for its intended purpose (shift left). I personally don't like to overload operators for purposes tangential to their intended use.

Bottom line: I'll use cout (and string) if I'm already using the STL. Otherwise, I tend to avoid it.

Using pymongo, you need to have both databases on same mongod, I did the following:

db = original database
db2 = database to be copied to

cursor = db["<collection to copy from>"].find()
for data in cursor:
    db2["<new collection>"].insert(data)

A const int var can be dynamically set to a value at runtime and once it is set to that value, it can no longer be changed.

A constexpr int var cannot be dynamically set at runtime, but rather, at compile time. And once it is set to that value, it can no longer be changed.

Here is a solid example:

int main(int argc, char*argv[]) {
    const int p = argc; 
    // p = 69; // cannot change p because it is a const
    // constexpr int q = argc; // cannot be, bcoz argc cannot be computed at compile time 
    constexpr int r = 2^3; // this works!
    // r = 42; // same as const too, it cannot be changed
}

The snippet above compiles fine and I have commented out those that cause it to error.

The key notions here to take note of, are the notions of compile time and run time. New innovations have been introduced into C++ intended to as much as possible ** know ** certain things at compilation time to improve performance at runtime.

Any attempt of explanation which does not involve the two key notions above, is hallucination.

curl -u username:password http://
curl -u username http://

From the documentation page:

-u, --user <user:password>

Specify the user name and password to use for server authentication. Overrides -n, --netrc and --netrc-optional.

If you simply specify the user name, curl will prompt for a password.

The user name and passwords are split up on the first colon, which makes it impossible to use a colon in the user name with this option. The password can, still.

When using Kerberos V5 with a Windows based server you should include the Windows domain name in the user name, in order for the server to succesfully obtain a Kerberos Ticket. If you don't then the initial authentication handshake may fail.

When using NTLM, the user name can be specified simply as the user name, without the domain, if there is a single domain and forest in your setup for example.

To specify the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLE\user and [email protected] respectively.

If you use a Windows SSPI-enabled curl binary and perform Kerberos V5, Negotiate, NTLM or Digest authentication then you can tell curl to select the user name and password from your environment by specifying a single colon with this option: "-u :".

If this option is used several times, the last one will be used.

http://curl.haxx.se/docs/manpage.html#-u

Note that you do not need --basic flag as it is the default.

Use the (ngModelChange) event to detect changes on the model

from sklearn import metrics
import bumpy as np
print(no.sqrt(metrics.mean_squared_error(actual,predicted)))

I found a simpler solution. If you have all the RPMs in the same directory, all you need to do is,

$ sudo rpm -i *.rpm

rpm seems to figure out the correct order to install these and installs the RPMs.

There is a Powershell script buried in the msdb forums that will script all the tables and related objects:

$s = new-object ('Microsoft.SqlServer.Management.Smo.Server') '<Servername>'

There are 2 version of the Java Environments, J2EE and Se. SE is the standard edition, which includes all the basic classes that you would need to write single user applications. While the Enterprise Edition is set up for multi-tiered enterprise applications, or possible distributed applications. If you'd be using app servers, like tomcat or websphere, you'd want to use the J2EE, with the extra classes for n-tier support.

since iterating over a string it will render an item for each char:

<li ng-repeat = "k in 'aaaa' track by $index">
   {{$index}} //THIS DOESN'T ANSWER OP'S QUESTION. Read below.
</li>

we can use this ugly but no-code workaround using the number|n decimal places native filter.

 <li ng-repeat="k in (0|number:mynumber -2 ) track by $index">
    {{$index}}
 </li>

this way we'll have mynumber elements with no extra code. Say '0.000'.
We use mynumber - 2 to compensate 0.
It won't work for numbers below 3, but might be useful in some cases.

To unstage everything at once, run this command

git reset HEAD -- .

A bit 'lazy' way to do this is to use startswith- it is easier to understand this rather regexps. However regexps might work faster, I haven't measured.

>>> papa = "papa is a good man"
>>> app = "app is important"
>>> strip_word = 'papa'
>>> papa[len(strip_word):] if papa.startswith(strip_word) else papa
' is a good man'
>>> app[len(strip_word):] if app.startswith(strip_word) else app
'app is important'

In C#, they are interchangeable (although method is the proper term) because you cannot write a method without incorporating it into a class. If it were independent of a class, then it would be a function. Methods are functions that operate through a designated class.

I like litter.

From their readme:

type Person struct {
  Name   string
  Age    int
  Parent *Person
}

litter.Dump(Person{
  Name:   "Bob",
  Age:    20,
  Parent: &Person{
    Name: "Jane",
    Age:  50,
  },
})

Sdump is pretty handy in tests:

func TestSearch(t *testing.T) {
  result := DoSearch()

  actual := litterOpts.Sdump(result)
  expected, err := ioutil.ReadFile("testdata.txt")
  if err != nil {
    // First run, write test data since it doesn't exist
        if !os.IsNotExist(err) {
      t.Error(err)
    }
    ioutil.Write("testdata.txt", actual, 0644)
    actual = expected
  }
  if expected != actual {
    t.Errorf("Expected %s, got %s", expected, actual)
  }
}

Guava API provides MoreCollectors.onlyElement() which is a collector that takes a stream containing exactly one element and returns that element.

The returned collector throws an IllegalArgumentException if the stream consists of two or more elements, and a NoSuchElementException if the stream is empty.

Refer the below code for usage:

import static com.google.common.collect.MoreCollectors.onlyElement;

Person matchingPerson = objects.stream
                        .filter(p -> p.email().equals("testemail"))
                        .collect(onlyElement());

GNU sed

sed '/\s*\(\S\+\s\+\)\{2\}\bsnow\(man\)\?\b/!d' file

Input:

C1    C2    C3    
1     a     snow   
2     b     snowman 
snow     c     sowman
      snow     snow     snowmanx

..output:

1     a     snow
2     b     snowman

Simplest and correct code is:

public static String[] toStringArray(JSONArray array) {
    if(array==null)
        return null;

    String[] arr=new String[array.length()];
    for(int i=0; i<arr.length; i++) {
        arr[i]=array.optString(i);
    }
    return arr;
}

Using List<String> is not a good idea, as you know the length of the array. Observe that it uses arr.length in for condition to avoid calling a method, i.e. array.length(), on each loop.

getting following error

It happens:  Error: 
      ngModel cannot be used to register form controls with a parent formGroup directive.  Try using
      formGroup's partner directive "formControlName" instead.  Example:

One way is to call A's constructor and pass self as an argument, like so:

class B(A):
    def __init__(self):
        A.__init__(self)
        print "hello"

The advantage of this style is that it's very clear. It call A's initialiser. The downside is that it doesn't handle diamond-shaped inheritance very well, since you may end up calling the shared base class's initialiser twice.

Another way is to use super(), as others have shown. For single-inheritance, it does basically the same thing as letting you call the parent's initialiser.

However, super() is quite a bit more complicated under-the-hood and can sometimes be counter-intuitive in multiple inheritance situations. On the plus side, super() can be used to handle diamond-shaped inheritance. If you want to know the nitty-gritty of what super() does, the best explanation I've found for how super() works is here (though I'm not necessarily endorsing that article's opinions).

u can simply use "width" attribute of "style" to change the length of the dropdown box

<select class="my_dropdown" id="my_dropdown" style="width:APPROPRIATE WIDTH IN PIXLES">
<option value="1">LONG OPTION</option>
<option value="2">short</option>
</select>

e.g.

style="width:200px"

I've created the PemUtils library that does exactly that. The code is available on GitHub and can be installed from NuGet:

PM> Install-Package PemUtils

or if you only want a DER converter:

PM> Install-Package DerConverter

Usage for reading a RSA key from PEM data:

using (var stream = File.OpenRead(path))
using (var reader = new PemReader(stream))
{
    var rsaParameters = reader.ReadRsaKey();
    // ...
}

new ArrayList( Arrays.asList( new String[]{"abc", "def"} ) );

any? isn't the same as not empty? in some cases.

>> [nil, 1].any?
=> true
>> [nil, nil].any?
=> false

From the documentation:

If the block is not given, Ruby adds an implicit block of {|obj| obj} (that is any? will return true if at least one of the collection members is not false or nil).

I just wanted to add to the great Flexbox solution described by Pavlo, that, in my case, I had two lists/columns of data that I wanted to display side-by-side with just a little spacing between, horizontally-centered inside an enclosing div. By nesting another div within the first (leftmost) flex:1 div and floating it right, I got just what I wanted. I couldn't find any other way to do this with consistent success at all viewport widths:

<div style="display:flex">
    <div style="flex:1;padding-right:15px">
        <div style="float:right">
            [My Left-hand list of stuff]
        </div>
    </div>

    <div style="flex:1;padding-left:15px">
            [My Right-hand list of stuff]
    </div>
</div>

TortoiseSVN -> Clean up...

I had the same error using Symfony 5 / Doctrine 2. One of my fields was named using a MySQL reserved word "order", causing a DBALException. When you want to use a reserved word, you have to escape it's name using back-ticks. In annotation form :

@ORM\Column(name="`order`", type="integer", nullable=false)

Here is a minimal example of how @property can be implemented:

class Thing:
    def __init__(self, my_word):
        self._word = my_word 
    @property
    def word(self):
        return self._word

>>> print( Thing('ok').word )
'ok'

Otherwise word remains a method instead of a property.

class Thing:
    def __init__(self, my_word):
        self._word = my_word
    def word(self):
        return self._word

>>> print( Thing('ok').word() )
'ok'

IF you want to select object with minimum or maximum property value. another way is to use Implementing IComparable.

public struct Money : IComparable<Money>
{
   public Money(decimal value) : this() { Value = value; }
   public decimal Value { get; private set; }
   public int CompareTo(Money other) { return Value.CompareTo(other.Value); }
}

Max Implementation will be.

var amounts = new List<Money> { new Money(20), new Money(10) };
Money maxAmount = amounts.Max();

Min Implementation will be.

var amounts = new List<Money> { new Money(20), new Money(10) };
Money maxAmount = amounts.Min();

In this way, you can compare any object and get the Max and Min while returning the object type.

Hope This will help someone.

BigDecimal is Oracle's arbitrary-precision numerical library. BigDecimal is part of the Java language and is useful for a variety of applications ranging from the financial to the scientific (that's where sort of am).

There's nothing wrong with using doubles for certain calculations. Suppose, however, you wanted to calculate Math.Pi * Math.Pi / 6, that is, the value of the Riemann Zeta Function for a real argument of two (a project I'm currently working on). Floating-point division presents you with a painful problem of rounding error.

BigDecimal, on the other hand, includes many options for calculating expressions to arbitrary precision. The add, multiply, and divide methods as described in the Oracle documentation below "take the place" of +, *, and / in BigDecimal Java World:

http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html

The compareTo method is especially useful in while and for loops.

Be careful, however, in your use of constructors for BigDecimal. The string constructor is very useful in many cases. For instance, the code

BigDecimal onethird = new BigDecimal("0.33333333333");

utilizes a string representation of 1/3 to represent that infinitely-repeating number to a specified degree of accuracy. The round-off error is most likely somewhere so deep inside the JVM that the round-off errors won't disturb most of your practical calculations. I have, from personal experience, seen round-off creep up, however. The setScale method is important in these regards, as can be seen from the Oracle documentation.

If you really need to encode UTF-8, you can try prepending the unicode byte order mark. I have no idea how widespread the support for this method is, but ZXing at least appears to support it: http://code.google.com/p/zxing/issues/detail?id=103

I've been reading up on QR Mode recently, and I think I've seen the same practice mentioned elsewhere, but I've not the foggiest where.

You can use following code

  DirectoryInfo di = Directory.CreateDirectory(path);

I just fixed this problem (Different Case with same error),
The answer above I tried may not work because My case were different but produced the same error.
I think my vendor libraries were jumbled,
I get this error by:
1. Pull from remote git, master branch is codeigniter then I do composer update on master branch, I wanted to work on laravel branch then I checkout and do composer update so I get the error,

Fatal error: Class 'Illuminate\Foundation\Application' not found in C:\cms\bootstrap\app.php on line 14

Solution: I delete the project on local and do a clone again, after that I checkout to my laravel file work's branch and do composer update then it is fixed.

In my case I downloaded version 22 of Android M and Android 5.1.1 using Android Studio 1.2.1.1 but when I try to do a Hello World this same error showed me

So the solution for me was doing right click in app like the image below and choose "Open Module Settings"

then there you have 2 options. I've changed both with the last version I had.

Compile SDK version to API 21 Lollipop

and Build Tools Version to 21.1.2

Finally clean the project and Build

UPDATED

TO Get Android Studio 1.3 follow these steps

1. Open the Settings window by choosing File > Settings.
2. Choose the Appearance & Behavior > System Settings > Updates panel.
3. On the Updates panel, choose the option Automatically check updates for: Canary Chanel.
4. On the Updates panel, select Check Now to check for the latest canary build. Download and install the build when you are prompted.

Then you'll have something like this to update your Androud Studio to 1.3 and with this you can test Android M

Update: Real Cause

This bug happens when the versions of SDK, Build Tools and Gradle Plugins doesn't match (in terms of compatibility). The solution is to verify whether you are using the latest version of them or not. The gradle plugins are placed in the build.gradle of the project, and the other versions are on the build.gradle of the module. For example, for SDK 23, you must use the Build Tools 23.0.1 and gradle plugins version 1.3.1.

Is this a simple eclipse java project without maven etc? In that case you will need to put the log4j2.xml file under src folder in order to be able to find it on the classpath. If you use maven put it under src/main/resources or src/test/resources

You can also use colnames instead of names if you have data.frame or matrix

try

$this->load->view('home/home_view',$data);

(and note the " ' " not the " ‘ " that you used)

I remember it this way:

1. IEnumerable has one method GetEnumerator() which allows one to read through the values in a collection but not write to it. Most of the complexity of using the enumerator is taken care of for us by the for each statement in C#. IEnumerable has one property: Current, which returns the current element.

2. ICollection implements IEnumerable and adds few additional properties the most use of which is Count. The generic version of ICollection implements the Add() and Remove() methods.

3. IList implements both IEnumerable and ICollection, and add the integer indexing access to items (which is not usually required, as ordering is done in database).

Try this:

Pattern p = Pattern.compile(?<=\\<(any_tag)\\>)(\\s*.*\\s*)(?=\\<\\/(any_tag)\\>);
Matcher m = p.matcher(anyString);

For example:

String str = "<TR> <TD>1Q Ene</TD> <TD>3.08%</TD> </TR>";
Pattern p = Pattern.compile("(?<=\\<TD\\>)(\\s*.*\\s*)(?=\\<\\/TD\\>)");
Matcher m = p.matcher(str);
while(m.find()){
   Log.e("Regex"," Regex result: " + m.group())       
}

Output:

10 Ene

3.08%
