NOTE: This one is just an alternative for the previous provided .NET framework 3.5 and above

You can send it as raw xml

<test>or like this</test>

If you declare the paramater2 as XElement data type

You would write a comparator class, for example:

struct CompareAge {
    bool operator()(Person const & p1, Person const & p2) {
        // return "true" if "p1" is ordered before "p2", for example:
        return p1.age < p2.age;
    }
};

and use that as the comparator argument:

priority_queue<Person, vector<Person>, CompareAge>

Using greater gives the opposite ordering to the default less, meaning that the queue will give you the lowest value rather than the highest.

If your main element has some child elements or text, you could make use of it.

Position your main element relative (or absolute/fixed) and use both :before and :after positioned absolute (in my situation it had to be absolute, don't know about your's).

Now if you want one more pseudo-element, attach an absolute :before to one of the main element's children (if you have only text, put it in a span, now you have an element), which is not relative/absolute/fixed.

This element will start acting like his owner is your main element.

HTML

<div class="circle">
    <span>Some text</span>
</div>

CSS

.circle {
    position: relative; /* or absolute/fixed */
}

.circle:before {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

.circle:after {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

.circle span {
    /* not relative/absolute/fixed */
}

.circle span:before {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

You need to use html helper, and you don't need to provide date format in model class. e.x :

@Html.TextBoxFor(m => m.ResgistrationhaseDate, "{0:dd/MM/yyyy}")

Because of the infinite superiority of Python over Java, Python has not one, but two toString operations.

One is __str__, the other is __repr__

__str__ will return a human readable string. __repr__ will return an internal representation.

__repr__ can be invoked on an object by calling repr(obj) or by using backticks `obj`.

When printing lists as well as other container classes, the contained elements will be printed using __repr__.

Have you tried using the DataTable.Select(filterExpression, sortExpression) method?

Use insert method from range, for example

Sub InsertColumn()
        Columns("C:C").Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
        Range("C1").Value = "Loc"
End Sub

PowerShell has built-in XML and XPath functions. You can use the Select-Xml cmdlet with an XPath query to select nodes from XML object and then .Node.'#text' to access node value.

[xml]$xml = Get-Content $serviceStatePath
$nodes = Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml
$nodes | ForEach-Object {$_.Node.'#text'}

Or shorter

[xml]$xml = Get-Content $serviceStatePath
Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml |
  % {$_.Node.'#text'}

In almost every case (that is: all cases except the very first ones), instance won't be null. Acquiring a lock is more costly than a simple check, so checking once the value of instance before locking is a nice and free optimization.

This pattern is called double-checked locking: http://en.wikipedia.org/wiki/Double-checked_locking

Python Force-suppress all exponential notation when printing numpy ndarrays, wrangle text justification, rounding and print options:

What follows is an explanation for what is going on, scroll to bottom for code demos.

Passing parameter suppress=True to function set_printoptions works only for numbers that fit in the default 8 character space allotted to it, like this:

import numpy as np
np.set_printoptions(suppress=True) #prevent numpy exponential 
                                   #notation on print, default False

#            tiny     med  large
a = np.array([1.01e-5, 22, 1.2345678e7])  #notice how index 2 is 8 
                                          #digits wide

print(a)    #prints [ 0.0000101   22.     12345678. ]

However if you pass in a number greater than 8 characters wide, exponential notation is imposed again, like this:

np.set_printoptions(suppress=True)

a = np.array([1.01e-5, 22, 1.2345678e10])    #notice how index 2 is 10
                                             #digits wide, too wide!

#exponential notation where we've told it not to!
print(a)    #prints [1.01000000e-005   2.20000000e+001   1.23456780e+10]

numpy has a choice between chopping your number in half thus misrepresenting it, or forcing exponential notation, it chooses the latter.

Here comes set_printoptions(formatter=...) to the rescue to specify options for printing and rounding. Tell set_printoptions to just print bare a bare float:

np.set_printoptions(suppress=True,
   formatter={'float_kind':'{:f}'.format})

a = np.array([1.01e-5, 22, 1.2345678e30])  #notice how index 2 is 30
                                           #digits wide.  

#Ok good, no exponential notation in the large numbers:
print(a)  #prints [0.000010 22.000000 1234567799999999979944197226496.000000] 

We've force-suppressed the exponential notation, but it is not rounded or justified, so specify extra formatting options:

np.set_printoptions(suppress=True,
   formatter={'float_kind':'{:0.2f}'.format})  #float, 2 units 
                                               #precision right, 0 on left

a = np.array([1.01e-5, 22, 1.2345678e30])   #notice how index 2 is 30
                                            #digits wide

print(a)  #prints [0.00 22.00 1234567799999999979944197226496.00]

The drawback for force-suppressing all exponential notion in ndarrays is that if your ndarray gets a huge float value near infinity in it, and you print it, you're going to get blasted in the face with a page full of numbers.

Notice that rounding is consistent at 2 units precision, and exponential notation is suppressed in both the very large e+x and very small e-x ranges.

Update: Looks like chartjs has been updated (see comment below). There are some examples up that look very nice:

1. Here's an example of updating a line chart using new data: http://jsbin.com/yitep/5/edit
2. Here's how we can update existing data on a line chart: http://jsbin.com/yitep/4/edit

Original Post

As of Nov 2013, there seem to be very few options for updating charts.

There is a good example here (duplicated below) of adding new points to a line chart. Still kind of jumpy but not too bad. However, I think the effect probably depends on the chart you are using.

It does look like this is somewhere in the development pipeline. I don't see any indication of a release date yet though: https://github.com/nnnick/Chart.js/issues/13 [Closed as of Jul 26, 2014]

Incase of lookup_food_array is array.

match_stage["favoriteFoods"] = {'$elemMatch': {'$in': lookup_food_array}}

Incase of lookup_food_array is string.

match_stage["favoriteFoods"] = {'$elemMatch': lookup_food_string}

To have newline in code you use _

Example:

Dim a As Integer
a = 500 _
  + 80 _
  + 90

MsgBox a

How does the max function work?

It looks for the "largest" item in an iterable. I'll assume that you can look up what that is, but if not, it's something you can loop over, i.e. a list or string.

What is use of the keyword key in max function? I know it is also used in context of sort function

Key is a lambda function that will tell max which objects in the iterable are larger than others. Say if you were sorting some object that you created yourself, and not something obvious, like integers.

Meaning of the lambda expression? How to read them? How do they work?

That's sort of a larger question. In simple terms, a lambda is a function you can pass around, and have other pieces of code use it. Take this for example:

def sum(a, b, f):
    return (f(a) + f(b))

This takes two objects, a and b, and a function f. It calls f() on each object, then adds them together. So look at this call:

>>> sum(2, 2, lambda a:  a * 2)
8

sum() takes 2, and calls the lambda expression on it. So f(a) becomes 2 * 2, which becomes 4. It then does this for b, and adds the two together.

In not so simple terms, lambdas come from lambda calculus, which is the idea of a function that returns a function; a very cool math concept for expressing computation. You can read about that here, and then actually understand it here.

It's probably better to read about this a little more, as lambdas can be confusing, and it's not immediately obvious how useful they are. Check here.

If you are looking for a popup in the page, that is not a new browser window, then I would take a look at the various "LightBox" implementations in Javascript.

Just ran into this problem myself. OSx Lion hides scrollbars while not in use to make it seem more "slick", but at the same time the issue you addressed comes up: people sometimes cannot see whether a div has a scroll feature or not.

The fix: In your css include -

  -webkit-appearance: none;
  width: 7px;
}

::-webkit-scrollbar-thumb {
  border-radius: 4px;
  background-color: rgba(0, 0, 0, .5);

In IntelliJ IDEA this happened to me when I imported a project that had been working fine and running with Java 1.7. I apparently hadn't notified IntelliJ that java 1.7 had been installed on my machine, and it wasn't finding my $JAVA_HOME.

On a Mac, this is resolved by:

Right clicking on the module | Module Settings | Project

and adding the 1.7 SDK by selecting "New" in the Project SDK.

Then go to the main IntelliJ IDEA menu | Preferences | Maven | Runner

and select the correct JRE. In my case it updated correctly Use Project SDK, which was now 1.7.

Is Button1 visible? I mean, from the server side. Make sure Button1.Visible is true.

Controls that aren't Visible won't be rendered in HTML, so although they are assigned a ClientID, they don't actually exist on the client side.

You should use the to_date function (oracle/functions/to_date.php )

SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = TO_DATE('23/04/49', 'DD/MM/YY');

If you want to align center on left attribute.
The same thing is for top alignment, you could use margin-top: (width/2 of your div), the concept is the same of left attribute.
It's important to set header element to position:relative.
try this:

#logo {
    background:red;
    height:50px;
    position:absolute;
    width:50px;
    left:50%;
    margin-left:-25px;
}

DEMO

If you would like to not use calculations you can do this:

#logo {
  background:red;
  width:50px;
  height:50px;
  position:absolute;
  left: 0;
  right: 0;
  margin: 0 auto;
}

Instead ofnull, use CustomerDTO customers =new CustomerDTO()`;

  private static List<Author> getAllAuthors() {
    initConnection();
    List<Author> authors = new ArrayList<Author>();
    Author author = new Author();
    try {
        stmt = (Statement) conn.createStatement();
        String str = "SELECT * FROM author";
        rs = (ResultSet) stmt.executeQuery(str);

        while (rs.next()) {
            int id = rs.getInt("nAuthorId");
            String name = rs.getString("cAuthorName");
            author.setnAuthorId(id);
            author.setcAuthorName(name);
            authors.add(author);
            System.out.println(author.getnAuthorId() + " - " + author.getcAuthorName());
        }
        rs.close();
        closeConnection();
    } catch (Exception e) {
        System.out.println(e);
    }
    return authors;

Actions vs Transformations

• Collect (Action) - Return all the elements of the dataset as an array at the driver program. This is usually useful after a filter or other operation that returns a sufficiently small subset of the data.

spark-sql doc

select(*cols) (transformation) - Projects a set of expressions and returns a new DataFrame.

Parameters: cols – list of column names (string) or expressions (Column). If one of the column names is ‘*’, that column is expanded to include all columns in the current DataFrame.**

df.select('*').collect()
[Row(age=2, name=u'Alice'), Row(age=5, name=u'Bob')]
df.select('name', 'age').collect()
[Row(name=u'Alice', age=2), Row(name=u'Bob', age=5)]
df.select(df.name, (df.age + 10).alias('age')).collect()
[Row(name=u'Alice', age=12), Row(name=u'Bob', age=15)]

Execution select(column-name1,column-name2,etc) method on a dataframe, returns a new dataframe which holds only the columns which were selected in the select() function.

e.g. assuming df has several columns including "name" and "value" and some others.

df2 = df.select("name","value")

df2 will hold only two columns ("name" and "value") out of the entire columns of df

df2 as the result of select will be in the executors and not in the driver (as in the case of using collect())

sql-programming-guide

df.printSchema()
# root
# |-- age: long (nullable = true)
# |-- name: string (nullable = true)

# Select only the "name" column
df.select("name").show()
# +-------+
# |   name|
# +-------+
# |Michael|
# |   Andy|
# | Justin|
# +-------+

You can running collect() on a dataframe (spark docs)

>>> l = [('Alice', 1)]
>>> spark.createDataFrame(l).collect()
[Row(_1=u'Alice', _2=1)]
>>> spark.createDataFrame(l, ['name', 'age']).collect()
[Row(name=u'Alice', age=1)]

spark docs

To print all elements on the driver, one can use the collect() method to first bring the RDD to the driver node thus: rdd.collect().foreach(println). This can cause the driver to run out of memory, though, because collect() fetches the entire RDD to a single machine; if you only need to print a few elements of the RDD, a safer approach is to use the take(): rdd.take(100).foreach(println).

Would it be possible for you to use a special command for saving these files?

If you do :set binary, :w and :set nobinary the file will be written without newline if there was none to start with.

This sequence of commands could be put into a user defined command or a mapping, of course.

A-M's is similar to what the BrowerActivity does. for FrameLayout.LayoutParams LayoutParameters = new FrameLayout.LayoutParams (768, 512);

I think we can use

FrameLayout.LayoutParams LayoutParameters = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.FILL_PARENT,
            FrameLayout.LayoutParams.FILL_PARENT) 

instead.

Another issue I met is if the video is playing, and user clicks the back button, next time, you go to this activity(singleTop one) and can not play the video. to fix this, I called the

try { 
    mCustomVideoView.stopPlayback();  
    mCustomViewCallback.onCustomViewHidden();
} catch(Throwable e) { //ignore }

in the activity's onBackPressed method.

You have a few options:

1. Using Enumerable.Where:

   list.Where(i => i.Property == value).FirstOrDefault();       // C# 3.0+
   

2. Using List.Find:

   list.Find(i => i.Property == value);                         // C# 3.0+
   list.Find(delegate(Item i) { return i.Property == value; }); // C# 2.0+
   

Both of these options return default(T) (null for reference types) if no match is found.

As mentioned in the comments below, you should use the appropriate form of comparison for your scenario:

• == for simple value types or where use of operator overloads are desired
• object.Equals(a,b) for most scenarios where the type is unknown or comparison has potentially been overridden
• string.Equals(a,b,StringComparison) for comparing strings
• object.ReferenceEquals(a,b) for identity comparisons, which are usually the fastest

So, this is an old post, however I think I can contribute something to it.

You can always do something like this:

package com.dyna.test;  

import java.io.File;  
import java.lang.reflect.Constructor;  

public class DynamicClass{  

  @SuppressWarnings("unchecked")  
  public Object castDynamicClass(String className, String value){  
    Class<?> dynamicClass;  

    try  
    {  
      //We get the actual .class object associated with the specified name  
      dynamicClass = Class.forName(className);  



    /* We get the constructor that received only 
     a String as a parameter, since the value to be used is a String, but we could
easily change this to be "dynamic" as well, getting the Constructor signature from
the same datasource we get the values from */ 


      Constructor<?> cons =  
        (Constructor<?>) dynamicClass.getConstructor(new Class<?>[]{String.class});  

      /*We generate our object, without knowing until runtime 
 what type it will be, and we place it in an Object as 
 any Java object extends the Object class) */  
      Object object = (Object) cons.newInstance(new Object[]{value});  

      return object;  
    }  
    catch (Exception e)  
    {  
      e.printStackTrace();  
    }  
    return null;  
  }  

  public static void main(String[] args)  
  {   
    DynamicClass dynaClass = new DynamicClass();  

    /* 
 We specify the type of class that should be used to represent 
 the value "3.0", in this case a Double. Both these parameters 
 you can get from a file, or a network stream for example. */  
    System.out.println(dynaClass.castDynamicClass("java.lang.Double", "3.0"));  

    /* 
We specify a different value and type, and it will work as 
 expected, printing 3.0 in the above case and the test path in the one below, as the Double.toString() and 
 File.toString() would do. */  
    System.out.println(dynaClass.castDynamicClass("java.io.File", "C:\\testpath"));  
  }  

Of course, this is not really dynamic casting, as in other languages (Python for example), because java is a statically typed lang. However, this can solve some fringe cases where you actually need to load some data in different ways, depending on some identifier. Also, the part where you get a constructor with a String parameter could be probably made more flexible, by having that parameter passed from the same data source. I.e. from a file, you get the constructor signature you want to use, and the list of values to be used, that way you pair up, say, the first parameter is a String, with the first object, casting it as a String, next object is an Integer, etc, but somehwere along the execution of your program, you get now a File object first, then a Double, etc.

In this way, you can account for those cases, and make a somewhat "dynamic" casting on-the-fly.

Hope this helps anyone as this keeps turning up in Google searches.

The API of java.io.File only supports getting the last modified time. And the Internet is very quiet on this topic as well.

Unless I missed something significant, the Java library as is (up to but not yet including Java 7) does not include this capability. So if you were desperate for this, one solution would be to write some C(++) code to call system routines and call it using JNI. Most of this work seems to be already done for you in a library called JNA, though.

You may still need to do a little OS specific coding in Java for this, though, as you'll probably not find the same system calls available in Windows and Unix/Linux/BSD/OS X.

You could simply have: var result = (str == "true").

Use vars()

class Foo(object):
    def __init__(self):
        self.a = 1
        self.b = 2

vars(Foo()) #==> {'a': 1, 'b': 2}
vars(Foo()).keys() #==> ['a', 'b']

Use TO_TIMESTAMP function

TO_TIMESTAMP(date_string,'YYYY-MM-DD HH24:MI:SS')

Use Photoshop, Paint.NET or similar software and adjust Hue.

There is something out there, context aware resizing, don't know if you will be able to use it, but it's worth looking at, that's for sure

A nice video demo (Enlarging appears towards the middle) http://www.youtube.com/watch?v=vIFCV2spKtg

Here there could be some code. http://www.semanticmetadata.net/2007/08/30/content-aware-image-resizing-gpl-implementation/

Was that overkill? Maybe there are some easy filters you can apply to an enlarged image to blur the pixels a bit, you could look into that.

Chrome can run as root (remember to use gksu when doing so) so long as you provide it with a profile directory.

Rather than type in the profile directory every time you want to run it, create a new bash file (I'd name it something like start-chrome.sh)

#/bin/bash
google-chrome --user-data-dir="/root/chrome-profile/"

Rember to call that script with root privelages!

$ gksu /root/start-chrome.sh

If you need to find the max/min of a hash, you can use #max_by or #min_by

people = {'joe' => 21, 'bill' => 35, 'sally' => 24}

people.min_by { |name, age| age } #=> ["joe", 21]
people.max_by { |name, age| age } #=> ["bill", 35]

I also recommend this program: http://www.timesynctool.com/

All of my applications have quit buttons... and I quite frequently get positive comments from users because of it. I don't care if the platform was designed in a fashion that applications shouldn't need them. Saying "don't put them there" is kind of ridiculous. If the user wants to quit... I provide them the access to do exactly that. I don't think it reduces how Android operates at all and seems like a good practice. I understand the life cycle... and my observation has been that Android doesn't do a good job at handling it.... and that is a basic fact.

There are two ways to achieve this.

1- As already proposed u can set the background of your spinner as custom 9 patch Image with all the adjustments made into it .

android:background="@drawable/btn_dropdown" 
android:clickable="true"
android:dropDownVerticalOffset="-10dip"
android:dropDownHorizontalOffset="0dip"
android:gravity="center"

If you want your Spinner to show With various different background colors i would recommend making the drop down image transparent, & loading that spinner in a relative layout with your color set in.

btn _dropdown is as:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:state_window_focused="false" android:state_enabled="true"
    android:drawable="@drawable/spinner_default" />
<item
    android:state_window_focused="false" android:state_enabled="false"
    android:drawable="@drawable/spinner_default" />
<item
    android:state_pressed="true"
    android:drawable="@drawable/spinner_pressed" />
<item
    android:state_focused="true" android:state_enabled="true"
    android:drawable="@drawable/spinner_pressed" />
<item
    android:state_enabled="true"
    android:drawable="@drawable/spinner_default" />
<item
    android:state_focused="true"
    android:drawable="@drawable/spinner_pressed" />
<item
    android:drawable="@drawable/spinner_default" />
</selector>

where the various states of pngwould define your various States of spinner seleti

Using your example, you could do:

public void doit(A a) {
    if(a instanceof B) {
        // needs to cast to B to access draw2 which isn't present in A
        // note that this is probably not a good OO-design, but that would
        // be out-of-scope for this discussion :)
        ((B)a).draw2();
    }
    a.draw();
}

Regarding Tom Beech's answer; I came up with the following instead:

public bool ValidateJSON(string s)
{
    try
    {
        JToken.Parse(s);
        return true;
    }
    catch (JsonReaderException ex)
    {
        Trace.WriteLine(ex);
        return false;
    }
}

With a usage of the following:

if (ValidateJSON(strMsg))
{
    var newGroup = DeserializeGroup(strMsg);
}

One approach is to do that using the String class itself. Let's say that your string is something like that:

String s = "some text";
boolean hasNonAlpha = s.matches("^.*[^a-zA-Z0-9 ].*$");

one other is to use an external library, such as Apache commons:

String s = "some text";
boolean hasNonAlpha = !StringUtils.isAlphanumeric(s);

You can make an Embedded class, which contains your two keys, and then have a reference to that class as EmbeddedId in your Entity.

You would need the @EmbeddedId and @Embeddable annotations.

@Entity
public class YourEntity {
    @EmbeddedId
    private MyKey myKey;

    @Column(name = "ColumnA")
    private String columnA;

    /** Your getters and setters **/
}

@Embeddable
public class MyKey implements Serializable {

    @Column(name = "Id", nullable = false)
    private int id;

    @Column(name = "Version", nullable = false)
    private int version;

    /** getters and setters **/
}

Another way to achieve this task is to use @IdClass annotation, and place both your id in that IdClass. Now you can use normal @Id annotation on both the attributes

@Entity
@IdClass(MyKey.class)
public class YourEntity {
   @Id
   private int id;
   @Id
   private int version;

}

public class MyKey implements Serializable {
   private int id;
   private int version;
}

This is the proper way to do it:

INSERT INTO destinationTable
SELECT * FROM sourceTable

I think the OP is asking the wrong question. The code below will show that it not necessary to manually raise the PropertyChanged EVENT from a dependency property to achieve the desired result. The way to do it is handle the PropertyChanged CALLBACK on the dependency property and set values for other dependency properties there. The following is a working example. In the code below, MyControl has two dependency properties - ActiveTabInt and ActiveTabString. When the user clicks the button on the host (MainWindow), ActiveTabString is modified. The PropertyChanged CALLBACK on the dependency property sets the value of ActiveTabInt. The PropertyChanged EVENT is not manually raised by MyControl.

If you want to use steffens21's approach with unittest.TestLoader, you can modify the original test loader (see unittest.py):

import unittest
from unittest import suite

class TestLoaderWithKwargs(unittest.TestLoader):
    """A test loader which allows to parse keyword arguments to the
       test case class."""
    def loadTestsFromTestCase(self, testCaseClass, **kwargs):
        """Return a suite of all tests cases contained in 
           testCaseClass."""
        if issubclass(testCaseClass, suite.TestSuite):
            raise TypeError("Test cases should not be derived from "\
                            "TestSuite. Maybe you meant to derive from"\ 
                            " TestCase?")
        testCaseNames = self.getTestCaseNames(testCaseClass)
        if not testCaseNames and hasattr(testCaseClass, 'runTest'):
            testCaseNames = ['runTest']

        # Modification here: parse keyword arguments to testCaseClass.
        test_cases = []
        for test_case_name in testCaseNames:
            test_cases.append(testCaseClass(test_case_name, **kwargs))
        loaded_suite = self.suiteClass(test_cases)

        return loaded_suite 

# call your test
loader = TestLoaderWithKwargs()

If you are on ubuntu, just install pyqt5 with apt-get command:

    sudo apt-get install python3-pyqt5   # for python3

or

    sudo apt-get install python-pyqt5    # for python2

However, on Ubuntu 14.04 the python-pyqt5 package is left out [source] and need to be installed manually [source]

Solution for Windows

Go to File --> Set Path and add the folder containing the functions as Matlab files. (At least for Matlab 2007b on Vista)

$files = glob($_SERVER["DOCUMENT_ROOT"]."/myFolder/*");

Following examples work for me, please note "is_user_defined" NOT "is_table_type"

IF TYPE_ID(N'idType') IS NULL
CREATE TYPE [dbo].[idType] FROM Bigint NOT NULL
go

IF not EXISTS (SELECT * FROM sys.types WHERE is_user_defined = 1 AND name = 'idType')
CREATE TYPE [dbo].[idType] FROM Bigint NOT NULL
go

To mock static method you should use a Powermock look at: https://github.com/powermock/powermock/wiki/MockStatic. Mockito doesn't provide this functionality.

What about an onclick function:

    <form id="form">
    <input type="text" name="firstInput">
    <button type="button" name="namebutton" 
           onClick="$('#gif').css('visibility', 'visible');
                    $('#form').submit();">
    </form>

Of course you can put this in a function and then trigger it with an onClick

This problem took me about one day, on one of mine ASP.NET MVC project fortunately i had the problem on my machine and not in production environment, so comparing web.config i see and removing that the error disappeared... a true challenge connect the SQL Server error 26 to this problem

I was able to solve this problem by executing this statement

sudo dpkg-reconfigure mysql-server-5.5

Which will change the root password.

You can also try this, after injecting $window service.

$window.location.reload();

You can also try this:

select MONTH(NOW())-MONTH(table_date) as 'Total Month Difference' from table_name;

OR

select MONTH(Newer_date)-MONTH(Older_date) as 'Total Month Difference' from table_Name;

A Fibbonacci sequence is one that sums the result of a number then we have added to the previous result, we should started from 1. I was trying to find a solution based on algorithm, so i build the recursive code, noticed that i keep the previous number and i changed the position. I'm searching the Fibbonacci sequence from 1 to 15.

public static void main(String args[]) {

    numbers(1,1,15);
}


public static int numbers(int a, int temp, int target)
{
    if(target <= a)
    {
        return a;
    }

    System.out.print(a + " ");

    a = temp + a;

    return numbers(temp,a,target);
}

Use this

$('body').on('change', '#id', function() {
  // Action goes here.
});

Well its very simple in controller you have somthing like this:

-- Controller

ViewBag.Profile_Id = new SelectList(db.Profiles, "Id", "Name", model.Profile_Id);

--View (Option A)

@Html.DropDownList("Profile_Id")

--View (Option B) --> Send a null value to the list

@Html.DropDownList("Profile_Id", null, "-- Choose --", new {  @class = "input-large" })

Look at rsync based Windows tool NASBackup. It will be a bonus if you are acquainted with rsync commands.

I like using the ggplot2 for this sort of thing:

df$Date <- as.Date( df$Date, '%m/%d/%Y')
require(ggplot2)
ggplot( data = df, aes( Date, Visits )) + geom_line() 

As Christian's answer with assign() shows, there is a way to assign in the global environment. A simpler, shorter (but not better ... stick with assign) way is to use the <<- operator, ie

    a <<- "new" 

inside the function.

Add a css reset to the top of your website style sheet, different browsers render some default margin and padding and perhaps external style sheets do something you are not aware of too, a css reset will just initialize a fresh palette so to speak:

html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, font, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, caption {
    margin: 0;
    padding: 0;
    border: 0;
    outline: 0;
    font-size: 100%;
    vertical-align: baseline;
    background: transparent;
}

UPDATE: Use the Universal Selector Instead: @Frank mentioned that you can use the Universal Selector: * instead of listing all the elements, and this selector looks like it is cross browser compatible in all major browsers:

* {
        margin: 0;
        padding: 0;
        border: 0;
        outline: 0;
        font-size: 100%;
        vertical-align: baseline;
        background: transparent;
    }

Have you tried setting the selection properties of your tableView like this:

tableView.allowsMultipleSelection = NO; tableView.allowsMultipleSelectionDuringEditing = YES; tableView.allowsSelection = NO; tableView.allowsSelectionDuringEditing YES; 

If you want more fine-grain control over when selection is allowed you can override - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath in your UITableView delegate. The documentation states:

Return Value An index-path object that confirms or alters the selected row. Return an NSIndexPath object other than indexPath if you want another cell to be selected. Return nil if you don't want the row selected. 

You can have this method return nil in cases where you don't want the selection to happen.

I'd like to add another vote for the StringFormat object. You can use this simply to specify "center, center" and the text will be drawn centrally in the rectangle or points provided:

StringFormat format = new StringFormat();
format.LineAlignment = StringAlignment.Center;
format.Alignment = StringAlignment.Center;

However there is one issue with this in CF. If you use Center for both values then it turns TextWrapping off. No idea why this happens, it appears to be a bug with the CF.

Remember, a for loop is essentially a fancy while loop. They're the same thing.

while <some condition is true> {
   // do some stuff
   // possibly do something to change the condition
}


for ( some var, <some condition is true>; increment var ) {

}

The advantage of a for loop is that it's harder to accidentally do an infinite loop. Or rather, it's more obvious when you do one because you generally put the loop var in the initial statement.

A while loop is more clear when you're not doing a standard incrementing pattern. For example:

int x = 1;
while( x != 10 ) {
  if ( some condition )
     x = 10;
  else 
     x += 5;
}

Best way to do this without blocking the UI thread is to use Async and Await introduced in .net 4.5.
You can paste this in your code just change the Browser to your webbrowser name. This way, your thread awaits the page to load, if it doesnt on time, it stops waiting and your code continues to run:

private async Task PageLoad(int TimeOut)
    {
        TaskCompletionSource<bool> PageLoaded = null;
        PageLoaded = new TaskCompletionSource<bool>();
        int TimeElapsed = 0;
        Browser.DocumentCompleted += (s, e) =>
        {
            if (Browser.ReadyState != WebBrowserReadyState.Complete) return;
            if (PageLoaded.Task.IsCompleted) return; PageLoaded.SetResult(true);
        };
        //
        while (PageLoaded.Task.Status != TaskStatus.RanToCompletion)
        {
            await Task.Delay(10);//interval of 10 ms worked good for me
            TimeElapsed++;
            if (TimeElapsed >= TimeOut * 100) PageLoaded.TrySetResult(true);
        }
    }

And you can use it like this, with in an async method, or in a button click event, just make it async:

private async void Button1_Click(object sender, EventArgs e)
{
   Browser.Navigate("www.example.com");
   await PageLoad(10);//await for page to load, timeout 10 seconds.
   //your code will run after the page loaded or timeout.
}

@tennisgent's solution is great. However, I think is a little limited.

Modularity and Encapsulation in Angular goes beyond routes. Based on the way the web is moving towards component-based development, it is important to apply this in directives as well.

As you already know, in Angular we can include templates (structure) and controllers (behavior) in pages and components. AngularCSS enables the last missing piece: attaching stylesheets (presentation).

For a full solution I suggest using AngularCSS.

1. Supports Angular's ngRoute, UI Router, directives, controllers and services.
2. Doesn't required to have ng-app in the <html> tag. This is important when you have multiple apps running on the same page
3. You can customize where the stylesheets are injected: head, body, custom selector, etc...
4. Supports preloading, persisting and cache busting
5. Supports media queries and optimizes page load via matchMedia API

https://github.com/door3/angular-css

Here are some examples:

Routes

  $routeProvider
    .when('/page1', {
      templateUrl: 'page1/page1.html',
      controller: 'page1Ctrl',
      /* Now you can bind css to routes */
      css: 'page1/page1.css'
    })
    .when('/page2', {
      templateUrl: 'page2/page2.html',
      controller: 'page2Ctrl',
      /* You can also enable features like bust cache, persist and preload */
      css: {
        href: 'page2/page2.css',
        bustCache: true
      }
    })
    .when('/page3', {
      templateUrl: 'page3/page3.html',
      controller: 'page3Ctrl',
      /* This is how you can include multiple stylesheets */
      css: ['page3/page3.css','page3/page3-2.css']
    })
    .when('/page4', {
      templateUrl: 'page4/page4.html',
      controller: 'page4Ctrl',
      css: [
        {
          href: 'page4/page4.css',
          persist: true
        }, {
          href: 'page4/page4.mobile.css',
          /* Media Query support via window.matchMedia API
           * This will only add the stylesheet if the breakpoint matches */
          media: 'screen and (max-width : 768px)'
        }, {
          href: 'page4/page4.print.css',
          media: 'print'
        }
      ]
    });

Directives

myApp.directive('myDirective', function () {
  return {
    restrict: 'E',
    templateUrl: 'my-directive/my-directive.html',
    css: 'my-directive/my-directive.css'
  }
});

Additionally, you can use the $css service for edge cases:

myApp.controller('pageCtrl', function ($scope, $css) {

  // Binds stylesheet(s) to scope create/destroy events (recommended over add/remove)
  $css.bind({ 
    href: 'my-page/my-page.css'
  }, $scope);

  // Simply add stylesheet(s)
  $css.add('my-page/my-page.css');

  // Simply remove stylesheet(s)
  $css.remove(['my-page/my-page.css','my-page/my-page2.css']);

  // Remove all stylesheets
  $css.removeAll();

});

Another solution, similar to Gerbus' solution, but this also works with relative font sizing.

ul {
    letter-spacing: -1em; /* Effectively collapses white-space */
}
ul li {
    display: inline;
    letter-spacing: normal; /* Reset letter-spacing to normal value */
}

I had this error and solution help which was posted by Anirudh. I built a template for express routing and forgot about this nuance - glad it was an easy fix.

I wanted to give a little clarification to his answer on where to put this code by explaining my file structure.

My typical file structure is as follows:

/lib

/routes

---index.js (controls the main navigation)

/page-one



/page-two



     ---index.js

(each file [in my case the index.js within page-two, although page-one would have an index.js too]- for each page - that uses app.METHOD or router.METHOD needs to have module.exports = router; at the end)

If someone wants I will post a link to github template that implements express routing using best practices. let me know

Thanks Anirudh!!! for the great answer.

The 'best' way to do this would be to set a property on a view object once the update is successful. You can then access this property in the view and inform the user accordingly.

Having said that it would be possible to trigger an alert from the controller code by doing something like this -

public ActionResult ActionName(PostBackData postbackdata)
{
    //your DB code
    return new JavascriptResult { Script = "alert('Successfully registered');" };
}

Use conditional statements at the top of the HTML document:

<!--[if lt IE 7 ]> <html lang="en" class="no-js ie6"> <![endif]-->
<!--[if IE 7 ]>    <html lang="en" class="no-js ie7"> <![endif]-->
<!--[if IE 8 ]>    <html lang="en" class="no-js ie8"> <![endif]-->
<!--[if IE 9 ]>    <html lang="en" class="no-js ie9"> <![endif]-->
<!--[if (gt IE 9)|!(IE)]><!--> <html lang="en" class="no-js"> <!--<![endif]-->

Then in the CSS add

.ie7 button { font-size:0;display:block;line-height:0 }

Either you use a framework or you write your own server with nodejs.

A simple fileserver may look like this:

import * as http from 'http';
import * as url from 'url';
import * as fs from 'fs';
import * as path from 'path';

var mimeTypes = {
     "html": "text/html",
     "jpeg": "image/jpeg",
     "jpg": "image/jpeg",
     "png": "image/png",
     "js": "text/javascript",
     "css": "text/css"};

http.createServer((request, response)=>{
    var pathname = url.parse(request.url).pathname;
    var filename : string;
    if(pathname === "/"){
        filename = "index.html";
    }
    else
        filename = path.join(process.cwd(), pathname);

    try{
        fs.accessSync(filename, fs.F_OK);
        var fileStream = fs.createReadStream(filename);
        var mimeType = mimeTypes[path.extname(filename).split(".")[1]];
        response.writeHead(200, {'Content-Type':mimeType});
        fileStream.pipe(response);
    }
    catch(e) {
            console.log('File not exists: ' + filename);
            response.writeHead(404, {'Content-Type': 'text/plain'});
            response.write('404 Not Found\n');
            response.end();
            return;
    }
    return;
    }
}).listen(5000);

I also faced this issue and see many absurd pages. I've learned that to make your app browsable, change the order of the XML elements, this this:

<activity
    android:name="com.example.MianActivityName"
    android:label="@string/title_activity_launcher">

    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>

    <intent-filter>                
        <data android:scheme="http" />     
        <!-- or you can use deep linking like  -->               

        <data android:scheme="http" android:host="xyz.abc.com"/>
        <action android:name="android.intent.action.VIEW"/>
        <category android:name="android.intent.category.BROWSABLE"/>
        <category android:name="android.intent.category.DEFAULT"/>

    </intent-filter>
</activity>

This worked for me and might help you.

There is big difference between dot (".") and text() :-

• The dot (".") in XPath is called the "context item expression" because it refers to the context item. This could be match with a node (such as an element, attribute, or text node) or an atomic value (such as a string, number, or boolean). While text() refers to match only element text which is in string form.

• The dot (".") notation is the current node in the DOM. This is going to be an object of type Node while Using the XPath function text() to get the text for an element only gets the text up to the first inner element. If the text you are looking for is after the inner element you must use the current node to search for the string and not the XPath text() function.

For an example :-

<a href="something.html">
  <img src="filename.gif">
  link
</a>

Here if you want to find anchor a element by using text link, you need to use dot ("."). Because if you use //a[contains(.,'link')] it finds the anchor a element but if you use //a[contains(text(),'link')] the text() function does not seem to find it.

Hope it will help you..:)

This is what worked for me: https://github.com/bumptech/glide/wiki/Custom-targets#overriding-default-behavior

import com.bumptech.glide.Glide;
import com.bumptech.glide.request.transition.Transition;
import com.bumptech.glide.request.target.BitmapImageViewTarget;

...

Glide.with(yourFragment)
  .load("yourUrl")
  .asBitmap()
  .into(new BitmapImageViewTarget(yourImageView) {
    @Override
    public void onResourceReady(Bitmap bitmap, Transition<? super Bitmap> anim) {
        super.onResourceReady(bitmap, anim);
        Palette.generateAsync(bitmap, new Palette.PaletteAsyncListener() {  
            @Override
            public void onGenerated(Palette palette) {
                // Here's your generated palette
                Palette.Swatch swatch = palette.getDarkVibrantSwatch();
                int color = palette.getDarkVibrantColor(swatch.getTitleTextColor());
            }
        });
    }
});

A curried function is applied to multiple argument lists, instead of just one.

Here is a regular, non-curried function, which adds two Int parameters, x and y:

scala> def plainOldSum(x: Int, y: Int) = x + y
plainOldSum: (x: Int,y: Int)Int
scala> plainOldSum(1, 2)
res4: Int = 3

Here is similar function that’s curried. Instead of one list of two Int parameters, you apply this function to two lists of one Int parameter each:

scala> def curriedSum(x: Int)(y: Int) = x + y
curriedSum: (x: Int)(y: Int)Intscala> second(2)
res6: Int = 3
scala> curriedSum(1)(2)
res5: Int = 3

What’s happening here is that when you invoke curriedSum, you actually get two traditional function invocations back to back. The first function invocation takes a single Int parameter named x , and returns a function value for the second function. This second function takes the Int parameter y.

Here’s a function named first that does in spirit what the first traditional function invocation of curriedSum would do:

scala> def first(x: Int) = (y: Int) => x + y
first: (x: Int)(Int) => Int

Applying 1 to the first function—in other words, invoking the first function and passing in 1 —yields the second function:

scala> val second = first(1)
second: (Int) => Int = <function1>

Applying 2 to the second function yields the result:

scala> second(2)
res6: Int = 3

This is what I needed to disable scrollbars while preserving scroll in Firefox, Chrome and Edge in :

          @-moz-document url-prefix() { /* Disable scrollbar Firefox */
            html{
              scrollbar-width: none;
            }
          }
          body {
            margin: 0; /* remove default margin */
            scrollbar-width: none; /* Also needed to disable scrollbar Firefox */
            -ms-overflow-style: none;  /* Disable scrollbar IE 10+ */
            overflow-y: scroll;
          }
          body::-webkit-scrollbar {
            width: 0px;
            background: transparent; /* Disable scrollbar Chrome/Safari/Webkit */
          }

Try this:

select Activity, SUM(Incomes.Amount) as "Total Amount 2009", SUM(Incomes2008.Amount) 
as "Total Amount 2008" from
Activities, Incomes, Incomes2008
where Activities.UnitName = ?  AND
Incomes.ActivityId = Activities.ActivityID  AND
Incomes2008.ActivityId = Activities.ActivityID GROUP BY
Activity ORDER BY Activity;

Basically you have to JOIN Incomes2008 table with the output of your first query.

Meanwhile this can be solved through a decorator in combination with Object.freeze or Object.defineProperty, I'm using this, it's a little bit prettier than using tons of getters. You can copy/paste this directly TS Playground to see it in action. - There are two options

Make individual fields "final"

The following decorator converts both, annotated static and non-static fields to "getter-only-properties".

Note: If an instance-variable with no initial value is annotated @final, then the first assigned value (no matter when) will be the final one.

// example
class MyClass {
    @final
    public finalProp: string = "You shall not change me!";

    @final
    public static FINAL_FIELD: number = 75;

    public static NON_FINAL: string = "I am not final."
}

var myInstance: MyClass = new MyClass();
myInstance.finalProp = "Was I changed?";
MyClass.FINAL_FIELD = 123;
MyClass.NON_FINAL = "I was changed.";

console.log(myInstance.finalProp);  // => You shall not change me!
console.log(MyClass.FINAL_FIELD);   // => 75
console.log(MyClass.NON_FINAL);     // => I was changed.

The Decorator: Make sure you include this in your code!

/**
* Turns static and non-static fields into getter-only, and therefor renders them "final".
* To use simply annotate the static or non-static field with: @final
*/
function final(target: any, propertyKey: string) {
    const value: any = target[propertyKey];
    // if it currently has no value, then wait for the first setter-call
    // usually the case with non-static fields
    if (!value) {
        Object.defineProperty(target, propertyKey, {
            set: function (value: any) {
                Object.defineProperty(this, propertyKey, {
                    get: function () {
                        return value;
                    },
                    enumerable: true,
                    configurable: false
                });
            },
            enumerable: true,
            configurable: true
        });
    } else { // else, set it immediatly
        Object.defineProperty(target, propertyKey, {
            get: function () {
                return value;
            },
            enumerable: true
        });
    }
}

As an alternative to the decorator above, there would also be a strict version of this, which would even throw an Error when someone tried to assign some value to the field with "use strict"; being set. (This is only the static part though)

/**
 * Turns static fields into getter-only, and therefor renders them "final".
 * Also throws an error in strict mode if the value is tried to be touched.
 * To use simply annotate the static field with: @strictFinal
 */
function strictFinal(target: any, propertyKey: string) {
    Object.defineProperty(target, propertyKey, {
        value: target[propertyKey],
        writable: false,
        enumerable: true
    });
}

Make every static field "final"

Possible Downside: This will only work for ALL statics of that class or for none, but cannot be applied to specific statics.

/**
* Freezes the annotated class, making every static 'final'.
* Usage:
* @StaticsFinal
* class MyClass {
*      public static SOME_STATIC: string = "SOME_STATIC";
*      //...
* }
*/
function StaticsFinal(target: any) {
    Object.freeze(target);
}

// Usage here
@StaticsFinal
class FreezeMe {
    public static FROZEN_STATIC: string = "I am frozen";
}

class EditMyStuff {
    public static NON_FROZEN_STATIC: string = "I am frozen";
}

// Test here
FreezeMe.FROZEN_STATIC = "I am not frozen.";
EditMyStuff.NON_FROZEN_STATIC = "I am not frozen.";

console.log(FreezeMe.FROZEN_STATIC); // => "I am frozen."
console.log(EditMyStuff.NON_FROZEN_STATIC); // => "I am not frozen."

Try this:

insert into [table] ([data])
output inserted.id, inserted.data into table2
select [data] from [external_table]

UPDATE: Re:

Denis - this seems very close to what I want to do, but perhaps you could fix the following SQL statement for me? Basically the [data] in [table1] and the [data] in [table2] represent two different/distinct columns from [external_table]. The statement you posted above only works when you want the [data] columns to be the same.

INSERT INTO [table1] ([data]) 
OUTPUT [inserted].[id], [external_table].[col2] 
INTO [table2] SELECT [col1] 
FROM [external_table] 

It's impossible to output external columns in an insert statement, so I think you could do something like this

merge into [table1] as t
using [external_table] as s
on 1=0 --modify this predicate as necessary
when not matched then insert (data)
values (s.[col1])
output inserted.id, s.[col2] into [table2]
;

To avoid the window losing focus when its returning to visible after being hidden all that is needed is:

setExtendedState(JFrame.NORMAL);

Like so:

defaultItem.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                showWindow();
                setExtendedState(JFrame.NORMAL);
            }
});

Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.

Create two string data type variables namely DirPath and FilePath. Set the value C:\backup\ to the variable DirPath. Do not set any value to the variable FilePath.

Select the variable FilePath and select F4 to view the properties. Set the EvaluateAsExpression property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)

As @Renat here already mentioned, proxied HTTP traffic comes in pretty normal HTTP requests. Make the request against the proxy, passing the full URL of the destination as the path.

var http = require ('http');

http.get ({
    host: 'my.proxy.com',
    port: 8080,
    path: 'http://nodejs.org/'
}, function (response) {
    console.log (response);
});

You can set the CSS of a notebook by calling a stylesheet from any cell. As an example, take a look at the 12 Steps to Navier Stokes course.

In particular, creating a file containing

<style>
    div.cell{
        width:100%;
        margin-left:1%;
        margin-right:auto;
    }
</style>

should give you a starting point. However, it may be necessary to also adjust e.g div.text_cell_render to deal with markdown as well as code cells.

If that file is custom.css then add a cell containing:

from IPython.core.display import HTML
def css_styling():
    styles = open("custom.css", "r").read()
    return HTML(styles)
css_styling()

This will apply all the stylings, and, in particular, change the cell width.

List membersList = Arrays.asList(membersArray);

returns immutable list, what you need to do is

new ArrayList<>(Arrays.asList(membersArray)); to make it mutable

@EnableConfigurationProperties needs to be there (you also can annotate your test class), the application-localtest.yml from test/resources will be loaded. A sample with jUnit5

@ExtendWith(SpringExtension.class)
@EnableConfigurationProperties
@ContextConfiguration(classes = {YourClasses}, initializers = ConfigFileApplicationContextInitializer.class)
@ActiveProfiles(profiles = "localtest")
class TestActiveProfile {

    @Test
    void testActiveProfile(){

    }
}

Update April 27, 2015

Up and coming to the HTML5 scene is the download attribute. It's supported in Firefox and Chrome, and soon to come to IE11. Depending on your needs, you could use it instead of an AJAX request (or using window.location) so long as the file you want to download is on the same origin as your site.

You could always make the AJAX request/window.location a fallback by using some JavaScript to test if download is supported and if not, switching it to call window.location.

Original answer

You can't have an AJAX request open the download prompt since you physically have to navigate to the file to prompt for download. Instead, you could use a success function to navigate to download.php. This will open the download prompt but won't change the current page.

$.ajax({
    url: 'download.php',
    type: 'POST',
    success: function() {
        window.location = 'download.php';
    }
});

Even though this answers the question, it's better to just use window.location and avoid the AJAX request entirely.

For an excel writer you might need the following:

In simple terms, inside a then handler function:

A) When x is a value (number, string, etc):

1. return x is equivalent to return Promise.resolve(x)
2. throw x is equivalent to return Promise.reject(x)

B) When x is a Promise that is already settled (not pending anymore):

1. return x is equivalent to return Promise.resolve(x), if the Promise was already resolved.
2. return x is equivalent to return Promise.reject(x), if the Promise was already rejected.

C) When x is a Promise that is pending:

1. return x will return a pending Promise, and it will be evaluated on the subsequent then.

Read more on this topic on the Promise.prototype.then() docs.

The line

Object EchoServer0;

says that you are allocating an Object named EchoServer0. This has nothing to do with the class EchoServer0. Furthermore, the object is not initialized, so EchoServer0 is null. Classes and identifiers have separate namespaces. This will actually compile:

String String = "abc";  // My use of String String was deliberate.

Please keep to the Java naming standards: classes begin with a capital letter, identifiers begin with a small letter, constants and enums are all-capitals.

public final String ME = "Eric Jablow";
public final double GAMMA = 0.5772;
public enum Color { RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO, VIOLET}
public COLOR background = Color.RED;

As we can see the raw method is slower the buffered.

variable declares and call like this in a class

class X {
    var x: Int = 3

}
var y = X()
print("value of x is: ", y.x)

//value of x is:  3

now you want to program to make the default value of x more than or equal to 3. Now take the hypothetical case if x is less than 3, your program will fail. so, you want people to either put 3 or more than 3. Swift got it easy for you and it is important to understand this bit-advance way of dating the variable value because they will extensively use in iOS development. Now let's see how get and set will be used here.

class X {
    var _x: Int = 3
    var x: Int {
        get {
            return _x
        }
        set(newVal) {  //set always take 1 argument
            if newVal >= 3 {
             _x = newVal //updating _x with the input value by the user
            print("new value is: ", _x)
            }
            else {
                print("error must be greater than 3")
            }
        }
    }
}
let y = X()
y.x = 1
print(y.x) //error must be greater than 3
y.x = 8 // //new value is: 8

if you still have doubts, just remember, the use of get and set is to update any variable the way we want it to be updated. get and set will give you better control to rule your logic. Powerful tool hence not easily understandable.

If MyCollection is going to be garbage collected anyway, then you shouldn't need to dispose it. Doing so will just churn the CPU more than necessary, and may even invalidate some pre-calculated analysis that the garbage collector has already performed.

I use IDisposable to do things like ensure threads are disposed correctly, along with unmanaged resources.

EDIT In response to Scott's comment:

The only time the GC performance metrics are affected is when a call the [sic] GC.Collect() is made"

Conceptually, the GC maintains a view of the object reference graph, and all references to it from the stack frames of threads. This heap can be quite large and span many pages of memory. As an optimisation, the GC caches its analysis of pages that are unlikely to change very often to avoid rescanning the page unnecessarily. The GC receives notification from the kernel when data in a page changes, so it knows that the page is dirty and requires a rescan. If the collection is in Gen0 then it's likely that other things in the page are changing too, but this is less likely in Gen1 and Gen2. Anecdotally, these hooks were not available in Mac OS X for the team who ported the GC to Mac in order to get the Silverlight plug-in working on that platform.

Another point against unnecessary disposal of resources: imagine a situation where a process is unloading. Imagine also that the process has been running for some time. Chances are that many of that process's memory pages have been swapped to disk. At the very least they're no longer in L1 or L2 cache. In such a situation there is no point for an application that's unloading to swap all those data and code pages back into memory to 'release' resources that are going to be released by the operating system anyway when the process terminates. This applies to managed and even certain unmanaged resources. Only resources that keep non-background threads alive must be disposed, otherwise the process will remain alive.

Now, during normal execution there are ephemeral resources that must be cleaned up correctly (as @fezmonkey points out database connections, sockets, window handles) to avoid unmanaged memory leaks. These are the kinds of things that have to be disposed. If you create some class that owns a thread (and by owns I mean that it created it and therefore is responsible for ensuring it stops, at least by my coding style), then that class most likely must implement IDisposable and tear down the thread during Dispose.

The .NET framework uses the IDisposable interface as a signal, even warning, to developers that the this class must be disposed. I can't think of any types in the framework that implement IDisposable (excluding explicit interface implementations) where disposal is optional.

For the benefit of people searching, it may be worth checking the input being decrypted. In my case, the info being sent for decryption was (wrongly) going in as an empty string. It resulted in the padding error.

This may relate to rossum's answer, but thought it worth mentioning.

This worked for me:

#!/bin/bash

git add `git status | grep modified | sed 's/\(.*modified:\s*\)//'`

Or even better:

$ git ls-files --modified | xargs git add

Simple! Add at the end of dockerfile:

ENTRYPOINT service mysql start && /bin/bash

You might want to take a look at Maven (http://maven.apache.org). You can use it either as the main build process for your application, or just to perform certain tasks through the Edit Configurations dialog. The process of creating a JAR of a module within Maven is fairly trivial, if you want it to include all the dependencies in a self-executable JAR that is trivial as well.

If you've never used Maven before then you want to read Better Builds With Maven.

I ran into this problem but my solution was twofold. 1.) I had to add an Android target version under project -> properties -> Android. 2.) I didn't have all google 'third party add-ons'. Click in AVD SDK manager under available packages -> third-party add-ons -> Google Inc. I downloaded all of the SDKs and that solved my issue.

On the Unity Editor open your project and:

1. Enable External option in Unity ? Preferences ? Packages ? Repository (only if Unity ver < 4.5)
2. Switch to Visible Meta Files in Edit ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Edit ? Project Settings ? Editor ? Asset Serialization Mode
4. Save Scene and Project from File menu.
5. Quit Unity and then you can delete the Library and Temp directory in the project directory. You can delete everything but keep the Assets and ProjectSettings directory.

If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:

cd to/your/unity/project/folder

git init

git add *

git commit -m "First commit"

git remote add origin [email protected]:username/project.git

git push -u origin master

You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).

Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.

And here's my own .gitignore recipe for my Unity projects:

# =============== #
# Unity generated #

Two Scoops of Django: Best Practices for Django 1.5 suggests using version control for your settings files and storing the files in a separate directory:

project/
    app1/
    app2/
    project/
        __init__.py
        settings/
            __init__.py
            base.py
            local.py
            production.py
    manage.py

The base.py file contains common settings (such as MEDIA_ROOT or ADMIN), while local.py and production.py have site-specific settings:

In the base file settings/base.py:

INSTALLED_APPS = (
    # common apps...
)

In the local development settings file settings/local.py:

from project.settings.base import *

DEBUG = True
INSTALLED_APPS += (
    'debug_toolbar', # and other apps for local development
)

In the file production settings file settings/production.py:

from project.settings.base import *

DEBUG = False
INSTALLED_APPS += (
    # other apps for production site
)

Then when you run django, you add the --settings option:

# Running django for local development
$ ./manage.py runserver 0:8000 --settings=project.settings.local

# Running django shell on the production site
$ ./manage.py shell --settings=project.settings.production

The authors of the book have also put up a sample project layout template on Github.

Performance. If you want the original insertion order there are the LinkedXXX classes, which maintain an additional linked list in insertion order. Most of the time you don't care, so you use a HashXXX, or you want a natural order, so you use TreeXXX. In either of those cases why should you pay the extra cost of the linked list?

The easiest way to do it is using Storyboard and a Segue.

Just create a Segue from the FirstViewController (not the Navigation Controller) of your TabBarController to a LoginViewController with the login UI and name it "showLogin".

Create a method that returns a BOOL to validate if the user logged in and/or his/her session is valid... preferably on the AppDelegate. Call it isSessionValid.

On your FirstViewController.m override the method viewDidAppear as follows:

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    if([self isSessionValid]==NO){
        [self performSegueWithIdentifier:@"showLogin" sender:self];
    }
}

Then if the user logged in successfully, just dismiss or pop-out the LoginViewController to show your tabs.

Works 100%!

Hope it helps!

You can do it without using plugins.

In the latest version of vscode that I'm using (1.17.0) you can simply open the branch that you want (from the bottom left menu) then press ctrl+shift+p and type Git: Merge branch and then choose the other branch that you want to merge from (to the current one)

The basic syntax for using ternary operator is like this:

(condition) ? (if_true) : (if_false)

For you case it is like this:

number < 0 ? bigInt.sign = 0 : bigInt.sign = 1;

I liked the look of WenhaoWuI's idea above, but I needed to identify the div with class .ui-tree in the PrimeNG tree component to set the height dynamically. All the answers I could find required the div to be named (ie #treediv) to enable the use of @ViewChild(), @ViewChildren(), @ContentChild(), @ContentChilden() etc. This was messy with a third party component.

I finally found a snippet from Günter Zöchbauer :

ngAfterViewInit() {
  this.elRef.nativeElement.querySelector('.myClass');
}

This made it easy:

@Input() height: number;
treeheight: number = 400; //default value

constructor(private renderer: Renderer2, private elRef: ElementRef) {  }

ngOnInit() {
    this.loading = true;
    if (this.height != null) {
        this.treeheight = this.height;
    }   
}

ngAfterViewInit() {
    this.renderer.setStyle(this.elRef.nativeElement.querySelector('.ui-tree'), 'height', this.treeheight + "px");
}

NodeJS (and newer browsers) have a nice shortcut to get the current time in milliseconds.

var timeInMss = Date.now()

Which has a performance boost compared with

var timeInMss = new Date().getTime()

Because you do not need to create a new object.

It's looking for an element with id list which has a property value equal to 2.
What you want is the option child of the list:

$("#list option[value='2']").text()

None, because having an ORM takes too much control away with small benefits. The time savings gained are easily blown away when you have to debug abnormalities resulting from the use of the ORM. Furthermore, ORMs discourage developers from learning SQL and how relational databases work and using this for their benefit.

Here's a point of view I haven't found in any of the other answers: use only one namespace. The main reason why namespaces are bad, according to most of the answers, is that you can have conflicting function names which can result in a total mess. However, this won't occur if you use only one namespace. Decide which library it is that you will use the most (maybe using namespace std;) and stick with it.

One can think of it as having an invisible library prefix - std::vector becomes just vector. This, in my opinion, is the best of both worlds: on one hand it reduces the amount of typing you have to do (as intended by namespaces) and on the other, it still requires you to use the prefixes for clarity and security. If there's a function or object without a namespace prefix - you know it's from the one namespace you declared.

Just remember that if you will decide to use one globally - don't use others locally. This comes back to the other answers that local namespaces are often more useful than global ones since they provide variety in convenience.

'So from this discussion i am thinking this should be the code then.

    Set sht = wb.Worksheets("Data")

    sht.Activate

As per bash - The Set Builtin manual, if -e/errexit is set, the shell exits immediately if a pipeline consisting of a single simple command, a list or a compound command returns a non-zero status.

By default, the exit status of a pipeline is the exit status of the last command in the pipeline, unless the pipefail option is enabled (it's disabled by default).

If so, the pipeline's return status of the last (rightmost) command to exit with a non-zero status, or zero if all commands exit successfully.

If you'd like to execute something on exit, try defining trap, for example:

trap onexit EXIT

where onexit is your function to do something on exit, like below which is printing the simple stack trace:

onexit(){ while caller $((n++)); do :; done; }

There is similar option -E/errtrace which would trap on ERR instead, e.g.:

trap onerr ERR

Examples

Zero status example:

$ true; echo $?
0

Non-zero status example:

$ false; echo $?
1

Negating status examples:

$ ! false; echo $?
0
$ false || true; echo $?
0

Test with pipefail being disabled:

$ bash -c 'set +o pipefail -e; true | true | true; echo success'; echo $?
success
0
$ bash -c 'set +o pipefail -e; false | false | true; echo success'; echo $?
success
0
$ bash -c 'set +o pipefail -e; true | true | false; echo success'; echo $?
1

Test with pipefail being enabled:

$ bash -c 'set -o pipefail -e; true | false | true; echo success'; echo $?
1

If you are reencoding in your ffmpeg command line, that may be the reason why it is CPU intensive. You need to simply copy the streams to the single container. Since I do not have your command line I cannot suggest a specific improvement here. Your acodec and vcodec should be set to copy is all I can say.

EDIT: On seeing your command line and given you have already tried it, this is for the benefit of others who come across the same question. The command:

ffmpeg -i rtsp://@192.168.241.1:62156 -acodec copy -vcodec copy c:/abc.mp4

will not do transcoding and dump the file for you in an mp4. Of course this is assuming the streamed contents are compatible with an mp4 (which in all probability they are).

I don't know anything about jquery so can't help you with that, but as far as Javascript is concerned you have an array of objects, so what you will only be able to access the names & values through each array element. E.g arr[0].name will give you 'k1', arr[1].value will give you 'hi'.

Maybe you want to do something like:

var obj = {};

obj.k1 = "abc";
obj.k2 = "hi";
obj.k3 = "oa";

alert ("obj.k2:" + obj.k2);

Whilst I love recursion in general, it's not as efficient as iteration when programming in C#, so perhaps the following solution is neater than the one suggested by John Myczek? This searches up a hierarchy from a given control to find an ancestor control of a particular type.

public static T FindVisualAncestorOfType<T>(this DependencyObject Elt)
    where T : DependencyObject
{
    for (DependencyObject parent = VisualTreeHelper.GetParent(Elt);
        parent != null; parent = VisualTreeHelper.GetParent(parent))
    {
        T result = parent as T;
        if (result != null)
            return result;
    }
    return null;
}

Call it like this to find the Window containing a control called ExampleTextBox:

Window window = ExampleTextBox.FindVisualAncestorOfType<Window>();

if you don't or cannot go through cursor and if you have only paths or File objects, you can use since API level 8 (2.2) public static Bitmap createVideoThumbnail (String filePath, int kind)

Android documentation

The following code runs perfectly:

Bitmap bMap = ThumbnailUtils.createVideoThumbnail(file.getAbsolutePath(), MediaStore.Video.Thumbnails.MICRO_KIND);

Make sure your model is not abstract. I actually made that mistake and it took a while, so I thought I'd post it.

Try this

index.html

<form action="form.php" method="post">
    Do you like stackoverflow?
    <input type="checkbox" name="like" value="Yes" />  
    <input type="submit" name="formSubmit" value="Submit" /> 
</form>

form.php

<html>
<head>
</head>
<body>

<?php
    if(isset($_POST['like']))
    {
        echo "<h1>You like Stackoverflow.<h1>";
    }
    else
    {
        echo "<h1>You don't like Stackoverflow.</h1>";
    }   
?>

</body>
</html>

Or this

<?php
    if(isset($_POST['like'])) && 
    $_POST['like'] == 'Yes') 
    {
        echo "You like Stackoverflow.";
    }
    else
    {
        echo "You don't like Stackoverflow.";
    }   
?>

These are 3 ways I use:

1. TextEncoder

new TextEncoder().encode("myString").length

2. Blob

new Blob(["myString"]).size

3. Buffer

Buffer.byteLength("myString", 'utf8')

you can also use for loop to append or write data to a file. example:

for i in {1..10}; do echo "Hello Linux Terminal"; >> file.txt done

">>" is used to append.

">" is used to write.

What language? and why use regex for this simple task?

If you must:

^(.*)/([^/]*)$

gives you the two parts you wanted. You might need to quote the parentheses:

^\(.*\)/\([^/]*\)$

depending on your preferred language syntax.

But I suggest you just use your language's string search function that finds the last "/" character, and split the string on that index.

The new version of Qt Creator also has a "profile" build option between debug and release. Here's how I'm detecting that:

CONFIG(debug, debug|release) {  DEFINES += DEBUG_MODE }
else:CONFIG(force_debug_info) { DEFINES += PROFILE_MODE }
else {                          DEFINES += RELEASE_MODE }

You have to Download the Jar called rs2xml by click this link rs2xml.jar Then Add it to your project libraries then import

import net.proteanit.sql.DbUtils;

I prepare Only a method to do so as a sample

private void Update_table(){
    try{
        // fetch a connection
        connection = your_connection_class_name_here.getInstance().getConnection();
        if (connection != null) {
        String sql="select name,description  from sell_mode";
        pst=connection.prepareStatement(sql);
        rs=pst.executeQuery();
         your_table_name_for_populating_your_Data.setModel(DbUtils.resultSetToTableModel(rs));
        }
    }
    catch(IOException | SQLException | PropertyVetoException e){
    JOptionPane.showMessageDialog(null,e);
    }
    finally {
          if (rs!= null) try { rs.close(); } catch (SQLException e) {}
          if (pst != null) try { pst.close(); } catch (SQLException e) {}
          if (connection != null) try { connection.close(); } catch (SQLException e) {}
      }
}

Hope this will help more

UPDATE (GEOCODE MULTIPLE ADDRESSES)

Here's the working Example Geocoding with multiple addresses.

 <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false">
 </script> 
 <script type="text/javascript">
  var delay = 100;
  var infowindow = new google.maps.InfoWindow();
  var latlng = new google.maps.LatLng(21.0000, 78.0000);
  var mapOptions = {
    zoom: 5,
    center: latlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }
  var geocoder = new google.maps.Geocoder(); 
  var map = new google.maps.Map(document.getElementById("map"), mapOptions);
  var bounds = new google.maps.LatLngBounds();

  function geocodeAddress(address, next) {
    geocoder.geocode({address:address}, function (results,status)
      { 
         if (status == google.maps.GeocoderStatus.OK) {
          var p = results[0].geometry.location;
          var lat=p.lat();
          var lng=p.lng();
          createMarker(address,lat,lng);
        }
        else {
           if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
            nextAddress--;
            delay++;

        next();
      }
    );
  }
 function createMarker(add,lat,lng) {
   var contentString = add;
   var marker = new google.maps.Marker({
     position: new google.maps.LatLng(lat,lng),
     map: map,
           });

  google.maps.event.addListener(marker, 'click', function() {
     infowindow.setContent(contentString);

  var nextAddress = 0;
  function theNext() {
    if (nextAddress < locations.length) {
      setTimeout('geocodeAddress("'+locations[nextAddress]+'",theNext)', delay);
      nextAddress++;
    } else {
      map.fitBounds(bounds);
    }
  }
  theNext();

</script>

As we can resolve this issue with setTimeout() function.

Still we should not geocode known locations every time you load your page as said by @geocodezip

Another alternatives of these are explained very well in the following links:

I found this on the MySQL support page for the Visual Studio connectors.

It appears that they do not support the MySQL to Visual Studio EXPRESS editions.

So to answer your question, yes you may need the ultimate version or professional edition - just not Express to be able to use MySQL with VS.

Nobody seems to address the case of summing elements of a vector that can have NaN values in it, e.g. numerical_limits<double>::quite_NaN()

I usually loop through the elements and bluntly check.

vector<double> x;

//...

size_t n = x.size();

double sum = 0;

for (size_t i = 0; i < n; i++){

  sum += (x[i] == x[i] ? x[i] : 0);

}

It's not fancy at all, i.e. no iterators or any other tricks but I this is how I do it. Some times if there are other things to do inside the loop and I want the code to be more readable I write

double val = x[i];

sum += (val == val ? val : 0);

//...

inside the loop and re-use val if needed.

I will make my contribution here... why? just because :p Its a different implementation, based on the Any LINQ extension, and a delegate. Here it is:

public static class Extensions
{
    public static int IndexOf<T>(
            this IEnumerable<T> list, 
            Predicate<T> condition) {               
        int i = -1;
        return list.Any(x => { i++; return condition(x); }) ? i : -1;
    }
}

void Main()
{
    TestGetsFirstItem();
    TestGetsLastItem();
    TestGetsMinusOneOnNotFound();
    TestGetsMiddleItem();   
    TestGetsMinusOneOnEmptyList();
}

void TestGetsFirstItem()
{
    // Arrange
    var list = new string[] { "a", "b", "c", "d" };

    // Act
    int index = list.IndexOf(item => item.Equals("a"));

    // Assert
    if(index != 0)
    {
        throw new Exception("Index should be 0 but is: " + index);
    }

    "Test Successful".Dump();
}

void TestGetsLastItem()
{
    // Arrange
    var list = new string[] { "a", "b", "c", "d" };

    // Act
    int index = list.IndexOf(item => item.Equals("d"));

    // Assert
    if(index != 3)
    {
        throw new Exception("Index should be 3 but is: " + index);
    }

    "Test Successful".Dump();
}

void TestGetsMinusOneOnNotFound()
{
    // Arrange
    var list = new string[] { "a", "b", "c", "d" };

    // Act
    int index = list.IndexOf(item => item.Equals("e"));

    // Assert
    if(index != -1)
    {
        throw new Exception("Index should be -1 but is: " + index);
    }

    var list = new string[] { "a", "b", "c", "d", "e" };

    // Act
    int index = list.IndexOf(item => item.Equals("c"));

    // Assert
    if(index != 2)
    {
        throw new Exception("Index should be 2 but is: " + index);
    }

    "Test Successful".Dump();
}        

Another way, which is a little bit easier for me is to use named pipes. Named pipes provided a way to synchronize and sending messages between different processes.

A.bash:

#!/bin/bash
msg="The Message"
echo $msg > A.pipe

B.bash:

#!/bin/bash
msg=`cat ./A.pipe`
echo "message from A : $msg"

Usage:

$ mkfifo A.pipe #You have to create it once
$ ./A.bash & ./B.bash # you have to run your scripts at the same time

B.bash will wait for message and as soon as A.bash sends the message, B.bash will continue its work.

Under "user" folder c://user, look at ".gitconfig" file then remove the http and proxy line.

You can easily use xml (from the Python standard library) to convert to a pandas.DataFrame. Here's what I would do (when reading from a file replace xml_data with the name of your file or file object):

import pandas as pd
import xml.etree.ElementTree as ET
import io

def iter_docs(author):
    author_attr = author.attrib
    for doc in author.iter('document'):
        doc_dict = author_attr.copy()
        doc_dict.update(doc.attrib)
        doc_dict['data'] = doc.text
        yield doc_dict

xml_data = io.StringIO(u'''\
<author type="XXX" language="EN" gender="xx" feature="xx" web="foobar.com">
    <documents count="N">
        <document KEY="e95a9a6c790ecb95e46cf15bee517651" web="www.foo_bar_exmaple.com"><![CDATA[A large text with lots of strings and punctuations symbols [...]

etree = ET.parse(xml_data) #create an ElementTree object 
doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))

If there are multiple authors in your original document or the root of your XML is not an author, then I would add the following generator:

def iter_author(etree):
    for author in etree.iter('author'):
        for row in iter_docs(author):
            yield row

and change doc_df = pd.DataFrame(list(iter_docs(etree.getroot()))) to doc_df = pd.DataFrame(list(iter_author(etree)))

Have a look at the ElementTree tutorial provided in the xml library documentation.

What worked for me was enabling the checkbox "Use Host GPU" when creating or editing the AVD (Android Virtual Device). This checkbox was not enabled by default.

Technical Answer

Abstract classes cannot be instantiated - this is by definition and design.

From the JLS, Chapter 8. Classes:

A named class may be declared abstract (§8.1.1.1) and must be declared abstract if it is incompletely implemented; such a class cannot be instantiated, but can be extended by subclasses.

From JSE 6 java doc for Classes.newInstance():

InstantiationException - if this Class represents an abstract class, an interface, an array class, a primitive type, or void; or if the class has no nullary constructor; or if the instantiation fails for some other reason.

You can, of course, instantiate a concrete subclass of an abstract class (including an anonymous subclass) and also carry out a typecast of an object reference to an abstract type.

A Different Angle On This - Teamplay & Social Intelligence:

This sort of technical misunderstanding happens frequently in the real world when we deal with complex technologies and legalistic specifications.

"People Skills" can be more important here than "Technical Skills". If competitively and aggressively trying to prove your side of the argument, then you could be theoretically right, but you could also do more damage in having a fight / damaging "face" / creating an enemy than it is worth. Be reconciliatory and understanding in resolving your differences. Who knows - maybe you're "both right" but working off slightly different meanings for terms??

Who knows - though not likely, it is possible the interviewer deliberately introduced a small conflict/misunderstanding to put you into a challenging situation and see how you behave emotionally and socially. Be gracious and constructive with colleagues, follow advice from seniors, and follow through after the interview to resolve any challenge/misunderstanding - via email or phone call. Shows you're motivated and detail-oriented.

editTxt.setOnFocusChangeListener { v, hasFocus ->
            val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
            if (hasFocus) {
                imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY)
            } else {
                imm.hideSoftInputFromWindow(v.windowToken, 0)

One way I found that helps with this is to use \include{file_with_tex_figure_commands}

(not input)

So, @Vivek has got the solution to the problem through a dialogue in the Comments rather than through an actual answer.

"The file is being created by user oracle just noticed this in our development database. i'm getting this error because, the directory where i try to create the file doesn't have write access for others and user oracle comes under others category. "

Who says SO is a Q&A site not a forum? Er, me, amongst others. Anyway, in the absence of an accepted answer to this question I proffer a link to an answer of mine on the topic of UTL_FILE.FOPEN(). Find it here.

P.S. I'm marking this answer Community Wiki, because it's not a proper answer to this question, just a redirect to somewhere else.

More detailed information are available in the platform module.

Don't forget to change profile in Provision Profile sections:

Ideally you should see Automatic in Code Signing Identity after you choose provision profile you need. If you don't see any option that's mean you don't have private key for current provision profile.

Your formula should be of the form =IF(X2 >= 85,0.559,IF(X2 >= 80,0.327,IF(X2 >=75,0.255,0))). This simulates the ELSE-IF operand Excel lacks. Your formulas were using two conditions in each, but the second parameter of the IF formula is the value to use if the condition evaluates to true. You can't chain conditions in that manner.

Applying the full_extent() function in an answer by @Joe 3 years later from here, you can get exactly what the OP was looking for. Alternatively, you can use Axes.get_tightbbox() which gives a little tighter bounding box

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np
from matplotlib.transforms import Bbox

def full_extent(ax, pad=0.0):
    """Get the full extent of an axes, including axes labels, tick labels, and
    titles."""
    # For text objects, we need to draw the figure first, otherwise the extents
    # are undefined.
    ax.figure.canvas.draw()
    items = ax.get_xticklabels() + ax.get_yticklabels() 
#    items += [ax, ax.title, ax.xaxis.label, ax.yaxis.label]
    items += [ax, ax.title]
    bbox = Bbox.union([item.get_window_extent() for item in items])

    return bbox.expanded(1.0 + pad, 1.0 + pad)

# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')

# Save the full figure...
fig.savefig('full_figure.png')

# Save just the portion _inside_ the second axis's boundaries
extent = full_extent(ax2).transformed(fig.dpi_scale_trans.inverted())
# Alternatively,
# extent = ax.get_tightbbox(fig.canvas.renderer).transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

I'd post a pic but I lack the reputation points

In the comments @libjack mentioned a point which is really important. I would like to illustrate more into it. First, we can check what are the columns of our table by describe <table_name>; command.

there is a double-column called _c1 and such columns are created by the hive itself when we moving data from one table to another. To address these columns we need to write it inside backticks

`_c1`

Finally, the ALTER command will be,

ALTER TABLE <table_namr> CHANGE `<system_genarated_column_name>` <new_column_name> <data_type>;

Edit: Although this question has been marked as a duplicate, it has still been getting attention. The answer provided by @JaKXz is correct and should be the accepted answer.

You'll need to check for the existence of the view. Then do a CREATE VIEW or ALTER VIEW depending on the result.

IF OBJECT_ID('dbo.data_VVVV') IS NULL
BEGIN
    CREATE VIEW dbo.data_VVVV
    AS
    SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A VCV
END
ELSE
    ALTER VIEW dbo.data_VVVV
    AS
    SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A VCV
BEGIN
END

 using (HttpClient client = new HttpClient())

        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

HttpResponseMessage response = client.PostAsync(url, new FormUrlEncodedContent(dict)).Result;
              var tokne= response.Content.ReadAsStringAsync().Result;
}

//Get response as expected

This answer might be very helpful for this problem. In addition, for my case, exporting the service as default was the cause.

WRONG:

@Inject()
export default class MobileService { ... }

CORRECT:

@Inject()
export class MobileService { ... }

Sleep meaning that thread is do nothing. Time is too large beacuse anthor thread query,but not disconnect server, default wait_timeout=28800;so you can set values smaller,eg 10. also you can kill the thread.

Use List.indexOf(). This will give you the first match when there are multiple duplicates.

I'm assuming you are using jQuery or something similar. If you are using jQuery, then the following should work:

<html>
<head>
   <script src="jquery.js" type="text/javascript"></script>
</head>
<body>
   content
</body>
<script type="text/javascript">
   $("body").load(url);
</script>
</html>

ExpressiveAnnotations gives you such a possibility:

[Required]
[AssertThat("Length(FieldA) + Length(FieldB) + Length(FieldC) + Length(FieldD) > 50")]
public string FieldA { get; set; }

Sorting such a vector or any other applicable (mutable input iterator) range of custom objects of type X can be achieved using various methods, especially including the use of standard library algorithms like

• sort,
• stable_sort,
• partial_sort or
• partial_sort_copy.

Since most of the techniques, to obtain relative ordering of X elements, have already been posted, I'll start by some notes on "why" and "when" to use the various approaches.

The "best" approach will depend on different factors:

1. Is sorting ranges of X objects a common or a rare task (will such ranges be sorted a mutiple different places in the program or by library users)?
2. Is the required sorting "natural" (expected) or are there multiple ways the type could be compared to itself?
3. Is performance an issue or should sorting ranges of X objects be foolproof?

If sorting ranges of X is a common task and the achieved sorting is to be expected (i.e. X just wraps a single fundamental value) then on would probably go for overloading operator< since it enables sorting without any fuzz (like correctly passing proper comparators) and repeatedly yields expected results.

If sorting is a common task or likely to be required in different contexts, but there are multiple criteria which can be used to sort X objects, I'd go for Functors (overloaded operator() functions of custom classes) or function pointers (i.e. one functor/function for lexical ordering and another one for natural ordering).

If sorting ranges of type X is uncommon or unlikely in other contexts I tend to use lambdas instead of cluttering any namespace with more functions or types.

This is especially true if the sorting is not "clear" or "natural" in some way. You can easily get the logic behind the ordering when looking at a lambda that is applied in-place whereas operator< is opague at first sight and you'd have to look the definition up to know what ordering logic will be applied.

Note however, that a single operator< definition is a single point of failure whereas multiple lambas are multiple points of failure and require a more caution.

If the definition of operator< isn't available where the sorting is done / the sort template is compiled, the compiler might be forced to make a function call when comparing objects, instead of inlining the ordering logic which might be a severe drawback (at least when link time optimization/code generation is not applied).

Ways to achieve comparability of class X in order to use standard library sorting algorithms

Let std::vector<X> vec_X; and std::vector<Y> vec_Y;

1. Overload T::operator<(T) or operator<(T, T) and use standard library templates that do not expect a comparison function.

Either overload member operator<:

struct X {
  int i{}; 
  bool operator<(X const &r) const { return i < r.i; } 
};
// ...
std::sort(vec_X.begin(), vec_X.end());

or free operator<:

struct Y {
  int j{}; 
};
bool operator<(Y const &l, Y const &r) { return l.j < r.j; }
// ...
std::sort(vec_Y.begin(), vec_Y.end());

2. Use a function pointer with a custom comparison function as sorting function parameter.

struct X {
  int i{};  
};
bool X_less(X const &l, X const &r) { return l.i < r.i; }
// ...
std::sort(vec_X.begin(), vec_X.end(), &X_less);

3. Create a bool operator()(T, T) overload for a custom type which can be passed as comparison functor.

struct X {
  int i{};  
  int j{};
};
struct less_X_i
{
    bool operator()(X const &l, X const &r) const { return l.i < r.i; }
};
struct less_X_j
{
    bool operator()(X const &l, X const &r) const { return l.j < r.j; }
};
// sort by i
std::sort(vec_X.begin(), vec_X.end(), less_X_i{});
// or sort by j
std::sort(vec_X.begin(), vec_X.end(), less_X_j{});

Those function object definitions can be written a little more generic using C++11 and templates:

struct less_i
{ 
    template<class T, class U>
    bool operator()(T&& l, U&& r) const { return std::forward<T>(l).i < std::forward<U>(r).i; }
};

which can be used to sort any type with member i supporting <.

4. Pass an anonymus closure (lambda) as comparison parameter to the sorting functions.

struct X {
  int i{}, j{};
};
std::sort(vec_X.begin(), vec_X.end(), [](X const &l, X const &r) { return l.i < r.i; });

Where C++14 enables a even more generic lambda expression:

std::sort(a.begin(), a.end(), [](auto && l, auto && r) { return l.i < r.i; });

which could be wrapped in a macro

#define COMPARATOR(code) [](auto && l, auto && r) -> bool { return code ; }

making ordinary comparator creation quite smooth:

// sort by i
std::sort(v.begin(), v.end(), COMPARATOR(l.i < r.i));
// sort by j
std::sort(v.begin(), v.end(), COMPARATOR(l.j < r.j));

If I understand you correctly, you want a list of all pictures with the same name (and their different ids) such that their name occurs more than once in the table. I think this will do the trick:

SELECT U.NAME, P.PIC_ID
FROM USERS U, PICTURES P, POSTINGS P1
WHERE U.EMAIL_ID = P1.EMAIL_ID AND P1.PIC_ID = P.PIC_ID AND U.Name IN (
SELECT U.Name 
FROM USERS U, PICTURES P, POSTINGS P1
WHERE U.EMAIL_ID = P1.EMAIL_ID AND P1.PIC_ID = P.PIC_ID AND P.CAPTION LIKE '%car%';
GROUP BY U.Name HAVING COUNT(U.Name) > 1)

I haven't executed it, so there may be a syntax error or two there.

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

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

It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment to your bean.

@Autowired
private Environment environment;
....

this.environment.getActiveProfiles();

In jQuery this is so:

$("span['property'=v:name]"); // for selecting your span element

It would seem likely that the ActiveWorkbook has not been saved...

Try CurDir() instead.

my start.sh file:

#/bin/bash

nohup forever -c php artisan your:command >>storage/logs/yourcommand.log 2>&1 &

There is one important thing only. FIRST COMMAND MUST BE "nohup", second command must be "forever" and "-c" parameter is forever's param, "2>&1 &" area is for "nohup". After running this line then you can logout from your terminal, relogin and run "forever restartall" voilaa... You can restart and you can be sure that if script halts then forever will restart it.

I think that both are functionally the same, but they simply have different authors, and the one is simply named more appropriately than the other.

Here is a quick backgrounder in naming conventions (for those unfamiliar), which explains the frustration by the question asker: For many *nix applications, the piece that does the backend work is called a "daemon" (think "service" in Windows-land), while the interface or client application is what you use to control or access the daemon. The daemon is most often named the same as the client, with the letter "d" appended to it. For example "imap" would be a client that connects to the "imapd" daemon.

This naming convention is clearly being adhered to by memcache when you read the introduction to the memcache module (notice the distinction between memcache and memcached in this excerpt):

Memcache module provides handy procedural and object oriented interface to memcached, highly effective caching daemon, which was especially designed to decrease database load in dynamic web applications.

The Memcache module also provides a session handler (memcache).

More information about memcached can be found at » http://www.danga.com/memcached/.

The frustration here is caused by the author of the PHP extension which was badly named memcached, since it shares the same name as the actual daemon called memcached. Notice also that in the introduction to memcached (the php module), it makes mention of libmemcached, which is the shared library (or API) that is used by the module to access the memcached daemon:

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

This extension uses libmemcached library to provide API for communicating with memcached servers. It also provides a session handler (memcached).

Information about libmemcached can be found at » http://tangent.org/552/libmemcached.html.

It's possible with a lot of work.

Basically, you have to post likes action via the Open Graph API. Then, you can add a custom design to your like button.

But then, you''ll need to keep track yourself of the likes so a returning user will be able to unlike content he liked previously.

Plus, you'll need to ask user to log into your app and ask them the publish_action permission.

All in all, if you're doing this for an application, it may worth it. For a website where you basically want user to like articles, then this is really to much.

Also, consider that you increase your drop-off rate each time you ask user a permission via a Facebook login.

If you want to see an example, I've recently made an app using the open graph like button, just hover on some photos in the mosaique to see it

Reason for me is 2 of following code in one xml

<?xml version="1.0" encoding="utf-8"?>

Try this Code

var app = angular.module('myapp', []);
  app.controller('testController', function ($scope, $http) {
       $scope.init = function(){           
       alert($scope.testInput);
   };});

<body ng-app="myapp">_x000D_
      <div ng-controller='testController' data-ng-init="testInput='value'; init();" class="col-sm-9 col-lg-9" >_x000D_
      </div>_x000D_
</body>

You are looking to calculate the time of the most recent celestial event where the sun has passed directly below your feet, adjusted for local conventions of marking high noon and also potentially adjusting so that people have enough daylight left after returning home from work, and for other political considerations.

Daunting right? Actually this is a common problem but the complete answer is location-dependent:

$zone = new \DateTimeZone('America/New_York'); // Or your own definition of “here”
$todayStart = new \DateTime('today midnight', $zone);
$timestamp = $todayStart->getTimestamp();

Potential definitions of “here” are listed at https://secure.php.net/manual/en/timezones.php

Library:

It is just a collection of routines (functional programming) or class definitions(object oriented programming). The reason behind is simply code reuse, i.e. get the code that has already been written by other developers. The classes or routines normally define specific operations in a domain specific area. For example, there are some libraries of mathematics which can let developer just call the function without redo the implementation of how an algorithm works.

Framework:

In framework, all the control flow is already there, and there are a bunch of predefined white spots that we should fill out with our code. A framework is normally more complex. It defines a skeleton where the application defines its own features to fill out the skeleton. In this way, your code will be called by the framework when appropriately. The benefit is that developers do not need to worry about if a design is good or not, but just about implementing domain specific functions.

Library,Framework and your Code image representation:

KeyDifference:

The key difference between a library and a framework is “Inversion of Control”. When you call a method from a library, you are in control. But with a framework, the control is inverted: the framework calls you. Source.

Relation:

Both of them defined API, which is used for programmers to use. To put those together, we can think of a library as a certain function of an application, a framework as the skeleton of the application, and an API is connector to put those together. A typical development process normally starts with a framework, and fill out functions defined in libraries through API.

event.target returns the node that was targeted by the function. This means you can do anything you want to do with any other node like one you'd get from document.getElementById

I'm tried with jQuery

var _target = e.target;
console.log(_target.attr('href'));

Return an error :

.attr not function

But _target.attributes.href.value was works.

I'm in windows 10, using WAMP64 server. Searched for my.cnf and my.ini. Found my.ini in C:\wamp64\bin\mariadb\mariadb10.2.14.

Following the instructions from the colleagues:

1. Opened the quick start menu from Wampserver, selected 'Stop All Services'
2. Opened my.ini in a text editor, searched for [mysqld]
3. Added 'skip-grant-tables' at the end of the [mysqld] section (but within it)
4. Save the file, leave the editor open
5. In the Wampserver menu, select "Restart Services'. There will be a warning about the skip-grant-tables option
6. In the Wampserver menu select MySQL to open the prompt
7. It asked for a password, just press enter
8. Paste the command ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'newpassword';
9. It must report that the operation was successful (no tables affected)
10. In the my.ini file, erase the 'skip-grant-tables' line, save the file
11. In the WampServer menu, select once more Restart Service

Now you can enter with the new password. Thanks to all answers here.

Windows 10 Home Edition does not have Local Users and Groups option so that is the reason you aren't able to see that in Computer Management.

IsNullOrWhiteSpace is a convenience method that is similar to the following code, except that it offers superior performance:

return String.IsNullOrEmpty(value) || value.Trim().Length == 0;

White-space characters are defined by the Unicode standard. The IsNullOrWhiteSpace method interprets any character that returns a value of true when it is passed to the Char.IsWhiteSpace method as a white-space character.

This isn't really recommended, but you can do it all inline like so:

<a href="#" onClick="function test(){ /* Do something */  } test(); return false;"></a>

But I can't think of any situations off hand where this would be better than writing the function somewhere else and invoking it onClick.

Here you are trying to execute IQueryable object on inactive DBContext. your DBcontext is already disposed of. you can only execute IQueryable object before DBContext is disposed of. Means you need to write users.Select(x => x.ToInfo()).ToList() statement inside using scope

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

Create docker image with openssh-server preinstalled:

Dockerfile

FROM ubuntu:16.04

RUN apt-get update && apt-get install -y openssh-server
RUN mkdir /var/run/sshd
RUN echo 'root:screencast' | chpasswd
RUN sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config

# SSH login fix. Otherwise user is kicked off after login
RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd

ENV NOTVISIBLE "in users profile"
RUN echo "export VISIBLE=now" >> /etc/profile

EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]

Build the image using:

$ docker build -t eg_sshd .

Run a test_sshd container:

$ docker run -d -P --name test_sshd eg_sshd
$ docker port test_sshd 22

0.0.0.0:49154

Ssh to your container:

$ ssh [email protected] -p 49154
# The password is ``screencast``.
root@f38c87f2a42d:/#

You must use CSS. Can't be done with PHP.

First, you'll need to tell git about yourself. Get your username and token together from your settings page.

Then run:

git config --global github.user YOUR_USERNAME
git config --global github.token YOURTOKEN

You will need to generate a new key if you don't have a back-up of your key.

Then you should be able to run:

git clone [email protected]:YOUR_USERNAME/YOUR_PROJECT.git

$yourString = "bla blaaa bla blllla bla bla";
$out = "";
if(strlen($yourString) > 22) {
    while(strlen($yourString) > 22) {
        $pos = strrpos($yourString, " ");
        if($pos !== false && $pos <= 22) {
            $out = substr($yourString,0,$pos);
            break;
        } else {
            $yourString = substr($yourString,0,$pos);
            continue;
        }
    }
} else {
    $out = $yourString;
}
echo "Output String: ".$out;

alter table table_name add primary key (col_name1, col_name2);

You may create a new list with an input of a previous list like so:

List one = new ArrayList()
//... add data, sort, etc
List two = new ArrayList(one);

This will allow you to modify the order or what elemtents are contained independent of the first list.

Keep in mind that the two lists will contain the same objects though, so if you modify an object in List two, the same object will be modified in list one.

example:

MyObject value1 = one.get(0);
MyObject value2 = two.get(0);
value1 == value2 //true
value1.setName("hello");
value2.getName(); //returns "hello"

Edit

To avoid this you need a deep copy of each element in the list like so:

List<Torero> one = new ArrayList<Torero>();
//add elements

List<Torero> two = new Arraylist<Torero>();
for(Torero t : one){
    Torero copy = deepCopy(t);
    two.add(copy);
}

with copy like the following:

public Torero deepCopy(Torero input){
    Torero copy = new Torero();
    copy.setValue(input.getValue());//.. copy primitives, deep copy objects again

    return copy;
}

string apppath = 
    (new System.IO.FileInfo
    (System.Reflection.Assembly.GetExecutingAssembly().CodeBase)).DirectoryName;

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;
GO

Add:

for i, v in enumerate(y):
    ax.text(v + 3, i + .25, str(v), color='blue', fontweight='bold')

result:

The y-values v are both the x-location and the string values for ax.text, and conveniently the barplot has a metric of 1 for each bar, so the enumeration i is the y-location.

Assuming you want curl installed: just execute the install command and see what happens.

As of version 2.4 of the Maven Dependency Plugin, you can also define a target destination for the artifact by using the -Ddest flag. It should point to a filename (not a directory) for the destination artifact. See the parameter page for additional parameters that can be used

mvn org.apache.maven.plugins:maven-dependency-plugin:2.4:get \
    -DremoteRepositories=http://download.java.net/maven/2 \
    -Dartifact=robo-guice:robo-guice:0.4-SNAPSHOT \
    -Ddest=c:\temp\robo-guice.jar

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

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

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

Now I can directly address the array:

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

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

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

<script>
function getFontsByScreenWidth(actuallFontSize, maxScreenWidth){
     return (actualFontSize / maxScreenWidth) * window.innerWidth;
}

// Example:
fontSize = 18;
maxScreenWidth = 1080;
fontSize = getFontsByScreenWidth(fontSize, maxScreenWidth)

</script>

I hope this will help. I am using this formula for my Phase game.

The currently accepted answer doesn't work. It creates thin vertical borders on the left and right sides of the view as a result of anti-aliasing.

This version works perfectly. It also allows you to set the border widths independently, and you can also add borders on the left / right sides if you want. The only drawback is that it does NOT support transparency.

Create an xml drawable named /res/drawable/top_bottom_borders.xml with the code below and assign it as a TextView's background property.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="#DDDD00" /> <!-- border color -->
        </shape>
    </item>

    <item
        android:bottom="1dp" 
        android:top="1dp">   <!-- adjust borders width here -->
        <shape android:shape="rectangle">
            <solid android:color="#FFFFFF" />  <!-- background color -->
        </shape>
    </item>
</layer-list>

There are several ways to remove a CSS property using jQuery:

1. Setting the CSS property to its default (initial) value

.css("background-color", "transparent")

See the initial value for the CSS property at MDN. Here the default value is transparent. You can also use inherit for several CSS properties to inherite the attribute from its parent. In CSS3/CSS4, you may also use initial, revert or unset but these keywords may have limited browser support.

2. Removing the CSS property

An empty string removes the CSS property, i.e.

.css("background-color","")

But beware, as specified in jQuery .css() documentation, this removes the property but it has compatibilty issues with IE8 for certain CSS shorthand properties, including background.

Setting the value of a style property to an empty string — e.g. $('#mydiv').css('color', '') — removes that property from an element if it has already been directly applied, whether in the HTML style attribute, through jQuery's .css() method, or through direct DOM manipulation of the style property. It does not, however, remove a style that has been applied with a CSS rule in a stylesheet or element. Warning: one notable exception is that, for IE 8 and below, removing a shorthand property such as border or background will remove that style entirely from the element, regardless of what is set in a stylesheet or element.

3. Removing the whole style of the element

.removeAttr("style")

In my case the error was caused by the insufficient memory allocated to the "test" lifecycle of maven. It was fixed by adding <argLine>-Xms3512m -Xmx3512m</argLine> to:

<pluginManagement>
  <plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.16</version>
        <configuration>
            <argLine>-Xms3512m -Xmx3512m</argLine>

Thanks @crazycoder for pointing this out (and also that it is not related to IntelliJ; in this case).

If your tests are forked, they run in a new JVM that doesn't inherit Maven JVM options. Custom memory options must be provided via the test runner in pom.xml, refer to Maven documentation for details, it has very little to do with the IDE.

An interface is like a set of genes that are publicly documented to have some kind of effect: A DNA test will tell me whether I've got them - and if I do, I can publicly make it known that I'm a "carrier" and part of my behavior or state will conform to them. (But of course, I may have many other genes that provide traits outside this scope.)

An abstract class is like the dead ancestor of a single-sex species(*): She can't be brought to life but a living (i.e. non-abstract) descendant inherits all her genes.

(*) To stretch this metaphor, let's say all members of the species live to the same age. This means all ancestors of a dead ancestor must also be dead - and likewise, all descendants of a living ancestor must be alive.

You can find the info here: http://www.php.net/manual/en/language.operators.comparison.php

It's scarce because it wasn't added until PHP4. What you have is fine though, if you know there may be a type difference then it's a much better comparison, since it's testing value and type in the comparison, not just value.

you should give permission on your db

grant execute on (packageName or tableName) to user;

If you chose to srand, it is a good idea to then call rand() at least once before you use it, because it is a kind of horrible primitive psuedo-random generator. See Stack Overflow question Why does rand() % 7 always return 0?.

srand(time(NULL));
rand();
//Now use rand()

If available, either random or arc4rand would be better.

Further to this, the return type is determined by

1. What the HTTP Request says it wants - in its Accept header. Try looking at the initial request as see what Accept is set to.

2. What HttpMessageConverters Spring sets up. Spring MVC will setup converters for XML (using JAXB) and JSON if Jackson libraries are on he classpath.

If there is a choice it picks one - in this example, it happens to be JSON.

This is covered in the course notes. Look for the notes on Message Convertors and Content Negotiation.

Simple vanilla JS code sample:

document.addEventListener('touchstart', handleTouchStart, false);        
document.addEventListener('touchmove', handleTouchMove, false);

var xDown = null;                                                        
var yDown = null;

function getTouches(evt) {
  return evt.touches ||             // browser API
         evt.originalEvent.touches; // jQuery
}                                                     

function handleTouchStart(evt) {
    const firstTouch = getTouches(evt)[0];                                      
    xDown = firstTouch.clientX;                                      
    yDown = firstTouch.clientY;                                      
};                                                

function handleTouchMove(evt) {
    if ( ! xDown || ! yDown ) {
        return;
    }

    var xUp = evt.touches[0].clientX;                                    
    var yUp = evt.touches[0].clientY;

    var xDiff = xDown - xUp;
    var yDiff = yDown - yUp;

    if ( Math.abs( xDiff ) > Math.abs( yDiff ) ) {/*most significant*/
        if ( xDiff > 0 ) {
            /* left swipe */ 
        } else {
            /* right swipe */
        }                       
    } else {
        if ( yDiff > 0 ) {
            /* up swipe */ 
        } else { 
            /* down swipe */
        }                                                                 
    }
    /* reset values */
    xDown = null;
    yDown = null;                                             
};
