Next release of ASP.NET MVC (available in January or so) should have MSBuild task that compiles views, so you might want to wait.

See announcement

Only add class create div and add class form-control. iam use JSP,boostrap4. Ignore c:foreach.

<div class="multi-select form-control" style="height:107.292px;">
        <div class="checkbox" id="checkbox-expedientes">
            <c:forEach var="item" items="${postulantes}">
                <label class="form-check-label">
                    <input id="options" class="postulantes" type="checkbox" value="1">Option 1</label>
            </c:forEach>
        </div>
    </div>

This will give DISTINCT values across all the columns:

SELECT DISTINCT value
FROM (
    SELECT DISTINCT a AS value FROM my_table
    UNION SELECT DISTINCT b AS value FROM my_table
    UNION SELECT DISTINCT c AS value FROM my_table
) AS derived

I think a lot of people are wanting to be able to check to see if their variable is not empty as well as if it exists. I think that checking for existence and emptiness is a good idea in a lot of cases, and makes your template more robust and less prone to silly errors. In other words, if you check to make sure your variable is not null AND not empty before using it, then your template becomes more flexible, because you can throw either a null variable or an empty string into it, and it will work the same in either case.

<#if p?? && p?has_content>1</#if>

Let's say you want to make sure that p is more than just whitespace. Then you could trim it before checking to see if it has_content.

<#if p?? && p?trim?has_content>1</#if>

UPDATE

Please ignore my suggestion -- has_content is all that is needed, as it does a null check along with the empty check. Doing p?? && p?has_content is equivalent to p?has_content, so you may as well just use has_content.

I've used this method successfully:

System.Reflection.Assembly.GetExecutingAssembly().CreateInstance(string className)

You'll need to cast the returned object to your desired object type.

In C99 (supported by clang and gcc) there's an obscure syntax for passing multi-dimensional arrays to functions by reference:

int l_matrix[10][20];

void test(int matrix_ptr[static 10][20]) {
}

int main(void) {
    test(l_matrix);
}

Unlike a plain pointer, this hints about array size, theoretically allowing compiler to warn about passing too-small array and spot obvious out of bounds access.

Sadly, it doesn't fix sizeof() and compilers don't seem to use that information yet, so it remains a curiosity.

I use the AbsoluteUri and you can get it like this:

string myURI = Request.Url.AbsoluteUri;
 if (!WebSecurity.IsAuthenticated) {
        Response.Redirect("~/Login?returnUrl="
            + Request.Url.AbsoluteUri );

Then after you login:

var returnUrl = Request.QueryString["returnUrl"];
 if(WebSecurity.Login(username,password,true)){
                Context.RedirectLocal(returnUrl);

It works well for me.

You can select the view, then under Attributes Inspector uncheck User Interaction Enabled .

For jQuery version < 1.9:

$('#inputId').attr('disabled', true);

For jQuery version >= 1.9:

$('#inputId').prop('disabled', true);

Generate pseudo random numbers between 1 and an [UPPER_LIMIT]

You can use the following to generate a number between 1 and an upper limit.

Math.abs(new Random().nextInt() % [UPPER_LIMIT]) + 1

Here is a specific example:

Example - Generate pseudo random numbers in the range 1 to 600:

Math.abs(new Random().nextInt() % 600) + 1

This will generate a random number within a range for you. In this case 1-600. You can change the value 600 to anything you need in the range of integers.

Generate pseudo random numbers between a [LOWER_LIMIT] and an [UPPER_LIMIT]

If you want to use a lower bound that is not equal to 1 then you can use the following formula.

Math.abs(new Random().nextInt() % ([UPPER_LIMIT] - [LOWER_LIMIT])) + [LOWER_LIMIT]

Here is a specific example:

Example - Generate pseudo random numbers in the range of 40 to 99:

Math.abs( new Random().nextInt() % (99 - 40) ) + 40

This will generate a random number within a range of 40 and 99.

In my situation the 'NUnit3 Test Adapter' has been disabled. To re-enable it go to menu

Tools->Extensions and Updates...

On the left side select 'Installed'->'All'.

On the upper right corner search for 'nunit'.

If you have 'NUnit3 Test Adapter' installed, with the found item you can enable/disable it.

String.toCharArray() creates new char array, means allocation of memory of string length, then copies original char array of string using System.arraycopy() and then returns this copy to caller. String.charAt() returns character at position i from original copy, that's why String.charAt() will be faster than String.toCharArray(). Although, String.toCharArray() returns copy and not char from original String array, where String.charAt() returns character from original char array. Code below returns value at the specified index of this string.

public char charAt(int index) {
    if ((index < 0) || (index >= value.length)) {
        throw new StringIndexOutOfBoundsException(index);
    }
    return value[index];
}

code below returns a newly allocated character array whose length is the length of this string

public char[] toCharArray() {
    // Cannot use Arrays.copyOf because of class initialization order issues
    char result[] = new char[value.length];
    System.arraycopy(value, 0, result, 0, value.length);
    return result;
}

I've just had some of the similar problems with scrollTop described here.

In the end I got around this on Firefox and IE by using the selector $('*').scrollTop(0);

Not perfect if you have elements you don't want to effect but it gets around the Document, Body, HTML and Window disparity. If it helps...

You can also do like this,

(for %i in (a b "c d") do @echo %~i)

The output will be,

a
b
c d

Note that when this is put in a batch file, '%' shall be doubled.

(for %%i in (a b "c d") do @echo %%~i)

Below are the steps that worked for me

1. Mount your google drive in google colab

   from google.colab import drive drive.mount('/content/drive')

2. Insert the directory

   import sys sys.path.insert(0,’/content/drive/My Drive/ColabNotebooks’)

3. check the current directory path

   %cd drive/MyDrive/ColabNotebooks %pwd

4. Import your module or file

   import my_module

5. If you get the following error 'Name Null is not defined' then do the following

   5.1 Download my_module.ipynb from colab as my_module.py file (file->Download .py)

   5.2 Upload the *.py file to drive/MyDrive/ColabNotebooks in Google drive

   5.3 import my_module will work now

The &nKByte creates a temporary value, which cannot be bound to a reference to non-const.

You could change void test(float *&x) to void test(float * const &x) or you could just drop the pointer altogether and use void test(float &x); /*...*/ test(nKByte);.

Perhaps a nice idiom for declaring constants for a class in Swift is to just use a struct named MyClassConstants like the following.

struct MyClassConstants{
    static let testStr = "test"
    static let testStrLength = countElements(testStr)

    static let arrayOfTests: [String] = ["foo", "bar", testStr]
}

In this way your constants will be scoped within a declared construct instead of floating around globally.

Update

I've added a static array constant, in response to a comment asking about static array initialization. See Array Literals in "The Swift Programming Language".

Notice that both string literals and the string constant can be used to initialize the array. However, since the array type is known the integer constant testStrLength cannot be used in the array initializer.

You can do it in this way

private EditText nameEdit;
private EditText emailEdit;
private String nameDefaultValue = "Your Name";
private String emailDefaultValue = "[email protected]";

and inside onCreate method

nameEdit = (EditText) findViewById(R.id.name);
    nameEdit.setText(nameDefaultValue); 
    nameEdit.setOnTouchListener( new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (nameEdit.getText().toString().equals(nameDefaultValue)){
                nameEdit.setText("");
            }
            return false;
        }
    });

    nameEdit.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {               
            if(!hasFocus && TextUtils.isEmpty(nameEdit.getText().toString())){
                nameEdit.setText(nameDefaultValue);
            } else if (hasFocus && nameEdit.getText().toString().equals(nameDefaultValue)){
                nameEdit.setText("");
            }
        }
    });     

    emailEdit = (EditText)findViewById(R.id.email);
    emailEdit.setText(emailDefaultValue);   
    emailEdit.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {               
            if(!hasFocus && TextUtils.isEmpty(emailEdit.getText().toString())){
                emailEdit.setText(emailDefaultValue);
            } else if (hasFocus && emailEdit.getText().toString().equals(emailDefaultValue)){
                emailEdit.setText("");
            }
        }
    });

Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.

e.g. if you do this:

SELECT 1 / 2

you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.

e.g.

SELECT CAST(1 AS DECIMAL) / 2

gives 0.500000

Thread.sleep can throw an InterruptedException which is a checked exception. All checked exceptions must either be caught and handled or else you must declare that your method can throw it. You need to do this whether or not the exception actually will be thrown. Not declaring a checked exception that your method can throw is a compile error.

You either need to catch it:

try {
    Thread.sleep(1000);
} catch (InterruptedException e) {
    e.printStackTrace();
    // handle the exception...        
    // For example consider calling Thread.currentThread().interrupt(); here.
}

Or declare that your method can throw an InterruptedException:

public static void main(String[]args) throws InterruptedException

I don't know if you only want the id of your dicts in the list to be unique, but if the goal is to have a set of dict where the unicity is on all keys' values.. you should use tuples key like this in your comprehension :

>>> L=[
...     {'id':1,'name':'john', 'age':34},
...    {'id':1,'name':'john', 'age':34}, 
...    {'id':2,'name':'hanna', 'age':30},
...    {'id':2,'name':'hanna', 'age':50}
...    ]
>>> len(L)
4
>>> L=list({(v['id'], v['age'], v['name']):v for v in L}.values())
>>>L
[{'id': 1, 'name': 'john', 'age': 34}, {'id': 2, 'name': 'hanna', 'age': 30}, {'id': 2, 'name': 'hanna', 'age': 50}]
>>>len(L)
3

Hope it helps you or another person having the concern....

Similarly in Java, you can create a S4 class in R that encapsulates your information:

setClass(Class="Person",
         representation(
            height="numeric",
            age="numeric"
          )
)

Then your function can return an instance of this class:

myFunction = function(age=28, height=176){
  return(new("Person",
          age=age,
          height=height))
}

and you can access your information:

aPerson = myFunction()

aPerson@age
aPerson@height

This did it for me simply and perfectly.

Decorator Basics

Python’s functions are objects

To understand decorators, you must first understand that functions are objects in Python. This has important consequences. Let’s see why with a simple example :

def shout(word="yes"):
    return word.capitalize()+"!"

print(shout())
# outputs : 'Yes!'

# As an object, you can assign the function to a variable like any other object 
scream = shout

# Notice we don't use parentheses: we are not calling the function,
# we are putting the function "shout" into the variable "scream".
# It means you can then call "shout" from "scream":

print(scream())
# outputs : 'Yes!'

# More than that, it means you can remove the old name 'shout',
# and the function will still be accessible from 'scream'

del shout
try:
    print(shout())
except NameError as e:
    print(e)
    #outputs: "name 'shout' is not defined"

print(scream())
# outputs: 'Yes!'

Keep this in mind. We’ll circle back to it shortly.

Another interesting property of Python functions is they can be defined inside another function!

def talk():

    # You can define a function on the fly in "talk" ...
    def whisper(word="yes"):
        return word.lower()+"..."

    # ... and use it right away!
    print(whisper())

# You call "talk", that defines "whisper" EVERY TIME you call it, then
# "whisper" is called in "talk". 
talk()
# outputs: 
# "yes..."

# But "whisper" DOES NOT EXIST outside "talk":

try:
    print(whisper())
except NameError as e:
    print(e)
    #outputs : "name 'whisper' is not defined"*
    #Python's functions are objects

Functions references

Okay, still here? Now the fun part...

You’ve seen that functions are objects. Therefore, functions:

• can be assigned to a variable
• can be defined in another function

That means that a function can return another function.

def getTalk(kind="shout"):

    # We define functions on the fly
    def shout(word="yes"):
        return word.capitalize()+"!"

    def whisper(word="yes") :
        return word.lower()+"...";

    # Then we return one of them
    if kind == "shout":
        # We don't use "()", we are not calling the function,
        # we are returning the function object
        return shout  
    else:
        return whisper

# How do you use this strange beast?

# Get the function and assign it to a variable
talk = getTalk()      

# You can see that "talk" is here a function object:
print(talk)
#outputs : <function shout at 0xb7ea817c>

# The object is the one returned by the function:
print(talk())
#outputs : Yes!

# And you can even use it directly if you feel wild:
print(getTalk("whisper")())
#outputs : yes...

There’s more!

If you can return a function, you can pass one as a parameter:

def doSomethingBefore(func): 
    print("I do something before then I call the function you gave me")
    print(func())

doSomethingBefore(scream)
#outputs: 
#I do something before then I call the function you gave me
#Yes!

Well, you just have everything needed to understand decorators. You see, decorators are “wrappers”, which means that they let you execute code before and after the function they decorate without modifying the function itself.

Handcrafted decorators

How you’d do it manually:

# A decorator is a function that expects ANOTHER function as parameter
def my_shiny_new_decorator(a_function_to_decorate):

    # Inside, the decorator defines a function on the fly: the wrapper.
    # This function is going to be wrapped around the original function
    # so it can execute code before and after it.
    def the_wrapper_around_the_original_function():

        # Put here the code you want to be executed BEFORE the original function is called
        print("Before the function runs")

        # Call the function here (using parentheses)
        a_function_to_decorate()

        # Put here the code you want to be executed AFTER the original function is called
        print("After the function runs")

    # At this point, "a_function_to_decorate" HAS NEVER BEEN EXECUTED.
    # We return the wrapper function we have just created.
    # The wrapper contains the function and the code to execute before and after. It’s ready to use!
    return the_wrapper_around_the_original_function

# Now imagine you create a function you don't want to ever touch again.
def a_stand_alone_function():
    print("I am a stand alone function, don't you dare modify me")

a_stand_alone_function() 
#outputs: I am a stand alone function, don't you dare modify me

# Well, you can decorate it to extend its behavior.
# Just pass it to the decorator, it will wrap it dynamically in 
# any code you want and return you a new function ready to be used:

a_stand_alone_function_decorated = my_shiny_new_decorator(a_stand_alone_function)
a_stand_alone_function_decorated()
#outputs:
#Before the function runs
#I am a stand alone function, don't you dare modify me
#After the function runs

Now, you probably want that every time you call a_stand_alone_function, a_stand_alone_function_decorated is called instead. That’s easy, just overwrite a_stand_alone_function with the function returned by my_shiny_new_decorator:

a_stand_alone_function = my_shiny_new_decorator(a_stand_alone_function)
a_stand_alone_function()
#outputs:
#Before the function runs
#I am a stand alone function, don't you dare modify me
#After the function runs

# That’s EXACTLY what decorators do!

Decorators demystified

The previous example, using the decorator syntax:

@my_shiny_new_decorator
def another_stand_alone_function():
    print("Leave me alone")

another_stand_alone_function()  
#outputs:  
#Before the function runs
#Leave me alone
#After the function runs

Yes, that’s all, it’s that simple. @decorator is just a shortcut to:

another_stand_alone_function = my_shiny_new_decorator(another_stand_alone_function)

Decorators are just a pythonic variant of the decorator design pattern. There are several classic design patterns embedded in Python to ease development (like iterators).

Of course, you can accumulate decorators:

def bread(func):
    def wrapper():
        print("</''''''\>")
        func()
        print("<\______/>")
    return wrapper

def ingredients(func):
    def wrapper():
        print("#tomatoes#")
        func()
        print("~salad~")
    return wrapper

def sandwich(food="--ham--"):
    print(food)

sandwich()
#outputs: --ham--
sandwich = bread(ingredients(sandwich))
sandwich()
#outputs:
#</''''''\>
# #tomatoes#
# --ham--
# ~salad~
#<\______/>

Using the Python decorator syntax:

@bread
@ingredients
def sandwich(food="--ham--"):
    print(food)

sandwich()
#outputs:
#</''''''\>
# #tomatoes#
# --ham--
# ~salad~
#<\______/>

The order you set the decorators MATTERS:

@ingredients
@bread
def strange_sandwich(food="--ham--"):
    print(food)

strange_sandwich()
#outputs:
##tomatoes#
#</''''''\>
# --ham--
#<\______/>
# ~salad~

Now: to answer the question...

As a conclusion, you can easily see how to answer the question:

# The decorator to make it bold
def makebold(fn):
    # The new function the decorator returns
    def wrapper():
        # Insertion of some code before and after
        return "<b>" + fn() + "</b>"
    return wrapper

# The decorator to make it italic
def makeitalic(fn):
    # The new function the decorator returns
    def wrapper():
        # Insertion of some code before and after
        return "<i>" + fn() + "</i>"
    return wrapper

@makebold
@makeitalic
def say():
    return "hello"

print(say())
#outputs: <b><i>hello</i></b>

# This is the exact equivalent to 
def say():
    return "hello"
say = makebold(makeitalic(say))

print(say())
#outputs: <b><i>hello</i></b>

You can now just leave happy, or burn your brain a little bit more and see advanced uses of decorators.

Taking decorators to the next level

Passing arguments to the decorated function

# It’s not black magic, you just have to let the wrapper 
# pass the argument:

def a_decorator_passing_arguments(function_to_decorate):
    def a_wrapper_accepting_arguments(arg1, arg2):
        print("I got args! Look: {0}, {1}".format(arg1, arg2))
        function_to_decorate(arg1, arg2)
    return a_wrapper_accepting_arguments

# Since when you are calling the function returned by the decorator, you are
# calling the wrapper, passing arguments to the wrapper will let it pass them to 
# the decorated function

@a_decorator_passing_arguments
def print_full_name(first_name, last_name):
    print("My name is {0} {1}".format(first_name, last_name))

print_full_name("Peter", "Venkman")
# outputs:
#I got args! Look: Peter Venkman
#My name is Peter Venkman

Decorating methods

One nifty thing about Python is that methods and functions are really the same. The only difference is that methods expect that their first argument is a reference to the current object (self).

That means you can build a decorator for methods the same way! Just remember to take self into consideration:

def method_friendly_decorator(method_to_decorate):
    def wrapper(self, lie):
        lie = lie - 3 # very friendly, decrease age even more :-)
        return method_to_decorate(self, lie)
    return wrapper


class Lucy(object):

    def __init__(self):
        self.age = 32

    @method_friendly_decorator
    def sayYourAge(self, lie):
        print("I am {0}, what did you think?".format(self.age + lie))

l = Lucy()
l.sayYourAge(-3)
#outputs: I am 26, what did you think?

If you’re making general-purpose decorator--one you’ll apply to any function or method, no matter its arguments--then just use *args, **kwargs:

def a_decorator_passing_arbitrary_arguments(function_to_decorate):
    # The wrapper accepts any arguments
    def a_wrapper_accepting_arbitrary_arguments(*args, **kwargs):
        print("Do I have args?:")
        print(args)
        print(kwargs)
        # Then you unpack the arguments, here *args, **kwargs
        # If you are not familiar with unpacking, check:
        # http://www.saltycrane.com/blog/2008/01/how-to-use-args-and-kwargs-in-python/
        function_to_decorate(*args, **kwargs)
    return a_wrapper_accepting_arbitrary_arguments

@a_decorator_passing_arbitrary_arguments
def function_with_no_argument():
    print("Python is cool, no argument here.")

function_with_no_argument()
#outputs
#Do I have args?:
#()
#{}
#Python is cool, no argument here.

@a_decorator_passing_arbitrary_arguments
def function_with_arguments(a, b, c):
    print(a, b, c)

function_with_arguments(1,2,3)
#outputs
#Do I have args?:
#(1, 2, 3)
#{}
#1 2 3 

@a_decorator_passing_arbitrary_arguments
def function_with_named_arguments(a, b, c, platypus="Why not ?"):
    print("Do {0}, {1} and {2} like platypus? {3}".format(a, b, c, platypus))

function_with_named_arguments("Bill", "Linus", "Steve", platypus="Indeed!")
#outputs
#Do I have args ? :
#('Bill', 'Linus', 'Steve')
#{'platypus': 'Indeed!'}
#Do Bill, Linus and Steve like platypus? Indeed!

class Mary(object):

    def __init__(self):
        self.age = 31

    @a_decorator_passing_arbitrary_arguments
    def sayYourAge(self, lie=-3): # You can now add a default value
        print("I am {0}, what did you think?".format(self.age + lie))

m = Mary()
m.sayYourAge()
#outputs
# Do I have args?:
#(<__main__.Mary object at 0xb7d303ac>,)
#{}
#I am 28, what did you think?

Passing arguments to the decorator

Great, now what would you say about passing arguments to the decorator itself?

This can get somewhat twisted, since a decorator must accept a function as an argument. Therefore, you cannot pass the decorated function’s arguments directly to the decorator.

Before rushing to the solution, let’s write a little reminder:

# Decorators are ORDINARY functions
def my_decorator(func):
    print("I am an ordinary function")
    def wrapper():
        print("I am function returned by the decorator")
        func()
    return wrapper

# Therefore, you can call it without any "@"

def lazy_function():
    print("zzzzzzzz")

decorated_function = my_decorator(lazy_function)
#outputs: I am an ordinary function

# It outputs "I am an ordinary function", because that’s just what you do:
# calling a function. Nothing magic.

@my_decorator
def lazy_function():
    print("zzzzzzzz")

#outputs: I am an ordinary function

It’s exactly the same. "my_decorator" is called. So when you @my_decorator, you are telling Python to call the function 'labelled by the variable "my_decorator"'.

This is important! The label you give can point directly to the decorator—or not.

Let’s get evil. ?

def decorator_maker():

    print("I make decorators! I am executed only once: "
          "when you make me create a decorator.")

    def my_decorator(func):

        print("I am a decorator! I am executed only when you decorate a function.")

        def wrapped():
            print("I am the wrapper around the decorated function. "
                  "I am called when you call the decorated function. "
                  "As the wrapper, I return the RESULT of the decorated function.")
            return func()

        print("As the decorator, I return the wrapped function.")

        return wrapped

    print("As a decorator maker, I return a decorator")
    return my_decorator

# Let’s create a decorator. It’s just a new function after all.
new_decorator = decorator_maker()       
#outputs:
#I make decorators! I am executed only once: when you make me create a decorator.
#As a decorator maker, I return a decorator

# Then we decorate the function

def decorated_function():
    print("I am the decorated function.")

decorated_function = new_decorator(decorated_function)
#outputs:
#I am a decorator! I am executed only when you decorate a function.
#As the decorator, I return the wrapped function

# Let’s call the function:
decorated_function()
#outputs:
#I am the wrapper around the decorated function. I am called when you call the decorated function.
#As the wrapper, I return the RESULT of the decorated function.
#I am the decorated function.

No surprise here.

Let’s do EXACTLY the same thing, but skip all the pesky intermediate variables:

def decorated_function():
    print("I am the decorated function.")
decorated_function = decorator_maker()(decorated_function)
#outputs:
#I make decorators! I am executed only once: when you make me create a decorator.
#As a decorator maker, I return a decorator
#I am a decorator! I am executed only when you decorate a function.
#As the decorator, I return the wrapped function.

# Finally:
decorated_function()    
#outputs:
#I am the wrapper around the decorated function. I am called when you call the decorated function.
#As the wrapper, I return the RESULT of the decorated function.
#I am the decorated function.

Let’s make it even shorter:

@decorator_maker()
def decorated_function():
    print("I am the decorated function.")
#outputs:
#I make decorators! I am executed only once: when you make me create a decorator.
#As a decorator maker, I return a decorator
#I am a decorator! I am executed only when you decorate a function.
#As the decorator, I return the wrapped function.

#Eventually: 
decorated_function()    
#outputs:
#I am the wrapper around the decorated function. I am called when you call the decorated function.
#As the wrapper, I return the RESULT of the decorated function.
#I am the decorated function.

Hey, did you see that? We used a function call with the "@" syntax! :-)

So, back to decorators with arguments. If we can use functions to generate the decorator on the fly, we can pass arguments to that function, right?

def decorator_maker_with_arguments(decorator_arg1, decorator_arg2):

    print("I make decorators! And I accept arguments: {0}, {1}".format(decorator_arg1, decorator_arg2))

    def my_decorator(func):
        # The ability to pass arguments here is a gift from closures.
        # If you are not comfortable with closures, you can assume it’s ok,
        # or read: https://stackoverflow.com/questions/13857/can-you-explain-closures-as-they-relate-to-python
        print("I am the decorator. Somehow you passed me arguments: {0}, {1}".format(decorator_arg1, decorator_arg2))

        # Don't confuse decorator arguments and function arguments!
        def wrapped(function_arg1, function_arg2) :
            print("I am the wrapper around the decorated function.\n"
                  "I can access all the variables\n"
                  "\t- from the decorator: {0} {1}\n"
                  "\t- from the function call: {2} {3}\n"
                  "Then I can pass them to the decorated function"
                  .format(decorator_arg1, decorator_arg2,
                          function_arg1, function_arg2))
            return func(function_arg1, function_arg2)

        return wrapped

    return my_decorator

@decorator_maker_with_arguments("Leonard", "Sheldon")
def decorated_function_with_arguments(function_arg1, function_arg2):
    print("I am the decorated function and only knows about my arguments: {0}"
           " {1}".format(function_arg1, function_arg2))

decorated_function_with_arguments("Rajesh", "Howard")
#outputs:
#I make decorators! And I accept arguments: Leonard Sheldon
#I am the decorator. Somehow you passed me arguments: Leonard Sheldon
#I am the wrapper around the decorated function. 
#I can access all the variables 
#   - from the decorator: Leonard Sheldon 
#   - from the function call: Rajesh Howard 
#Then I can pass them to the decorated function
#I am the decorated function and only knows about my arguments: Rajesh Howard

Here it is: a decorator with arguments. Arguments can be set as variable:

c1 = "Penny"
c2 = "Leslie"

@decorator_maker_with_arguments("Leonard", c1)
def decorated_function_with_arguments(function_arg1, function_arg2):
    print("I am the decorated function and only knows about my arguments:"
           " {0} {1}".format(function_arg1, function_arg2))

decorated_function_with_arguments(c2, "Howard")
#outputs:
#I make decorators! And I accept arguments: Leonard Penny
#I am the decorator. Somehow you passed me arguments: Leonard Penny
#I am the wrapper around the decorated function. 
#I can access all the variables 
#   - from the decorator: Leonard Penny 
#   - from the function call: Leslie Howard 
#Then I can pass them to the decorated function
#I am the decorated function and only know about my arguments: Leslie Howard

As you can see, you can pass arguments to the decorator like any function using this trick. You can even use *args, **kwargs if you wish. But remember decorators are called only once. Just when Python imports the script. You can't dynamically set the arguments afterwards. When you do "import x", the function is already decorated, so you can't change anything.

Let’s practice: decorating a decorator

Okay, as a bonus, I'll give you a snippet to make any decorator accept generically any argument. After all, in order to accept arguments, we created our decorator using another function.

We wrapped the decorator.

Anything else we saw recently that wrapped function?

Oh yes, decorators!

Let’s have some fun and write a decorator for the decorators:

def decorator_with_args(decorator_to_enhance):
    """ 
    This function is supposed to be used as a decorator.
    It must decorate an other function, that is intended to be used as a decorator.
    Take a cup of coffee.
    It will allow any decorator to accept an arbitrary number of arguments,
    saving you the headache to remember how to do that every time.
    """

    # We use the same trick we did to pass arguments
    def decorator_maker(*args, **kwargs):

        # We create on the fly a decorator that accepts only a function
        # but keeps the passed arguments from the maker.
        def decorator_wrapper(func):

            # We return the result of the original decorator, which, after all, 
            # IS JUST AN ORDINARY FUNCTION (which returns a function).
            # Only pitfall: the decorator must have this specific signature or it won't work:
            return decorator_to_enhance(func, *args, **kwargs)

        return decorator_wrapper

    return decorator_maker

It can be used as follows:

# You create the function you will use as a decorator. And stick a decorator on it :-)
# Don't forget, the signature is "decorator(func, *args, **kwargs)"
@decorator_with_args 
def decorated_decorator(func, *args, **kwargs): 
    def wrapper(function_arg1, function_arg2):
        print("Decorated with {0} {1}".format(args, kwargs))
        return func(function_arg1, function_arg2)
    return wrapper

# Then you decorate the functions you wish with your brand new decorated decorator.

@decorated_decorator(42, 404, 1024)
def decorated_function(function_arg1, function_arg2):
    print("Hello {0} {1}".format(function_arg1, function_arg2))

decorated_function("Universe and", "everything")
#outputs:
#Decorated with (42, 404, 1024) {}
#Hello Universe and everything

# Whoooot!

I know, the last time you had this feeling, it was after listening a guy saying: "before understanding recursion, you must first understand recursion". But now, don't you feel good about mastering this?

Best practices: decorators

• Decorators were introduced in Python 2.4, so be sure your code will be run on >= 2.4.
• Decorators slow down the function call. Keep that in mind.
• You cannot un-decorate a function. (There are hacks to create decorators that can be removed, but nobody uses them.) So once a function is decorated, it’s decorated for all the code.
• Decorators wrap functions, which can make them hard to debug. (This gets better from Python >= 2.5; see below.)

The functools module was introduced in Python 2.5. It includes the function functools.wraps(), which copies the name, module, and docstring of the decorated function to its wrapper.

(Fun fact: functools.wraps() is a decorator! ?)

# For debugging, the stacktrace prints you the function __name__
def foo():
    print("foo")

print(foo.__name__)
#outputs: foo

# With a decorator, it gets messy    
def bar(func):
    def wrapper():
        print("bar")
        return func()
    return wrapper

@bar
def foo():
    print("foo")

print(foo.__name__)
#outputs: wrapper

# "functools" can help for that

import functools

def bar(func):
    # We say that "wrapper", is wrapping "func"
    # and the magic begins
    @functools.wraps(func)
    def wrapper():
        print("bar")
        return func()
    return wrapper

@bar
def foo():
    print("foo")

print(foo.__name__)
#outputs: foo

How can the decorators be useful?

Now the big question: What can I use decorators for?

Seem cool and powerful, but a practical example would be great. Well, there are 1000 possibilities. Classic uses are extending a function behavior from an external lib (you can't modify it), or for debugging (you don't want to modify it because it’s temporary).

You can use them to extend several functions in a DRY’s way, like so:

def benchmark(func):
    """
    A decorator that prints the time a function takes
    to execute.
    """
    import time
    def wrapper(*args, **kwargs):
        t = time.clock()
        res = func(*args, **kwargs)
        print("{0} {1}".format(func.__name__, time.clock()-t))
        return res
    return wrapper


def logging(func):
    """
    A decorator that logs the activity of the script.
    (it actually just prints it, but it could be logging!)
    """
    def wrapper(*args, **kwargs):
        res = func(*args, **kwargs)
        print("{0} {1} {2}".format(func.__name__, args, kwargs))
        return res
    return wrapper


def counter(func):
    """
    A decorator that counts and prints the number of times a function has been executed
    """
    def wrapper(*args, **kwargs):
        wrapper.count = wrapper.count + 1
        res = func(*args, **kwargs)
        print("{0} has been used: {1}x".format(func.__name__, wrapper.count))
        return res
    wrapper.count = 0
    return wrapper

@counter
@benchmark
@logging
def reverse_string(string):
    return str(reversed(string))

print(reverse_string("Able was I ere I saw Elba"))
print(reverse_string("A man, a plan, a canoe, pasta, heros, rajahs, a coloratura, maps, snipe, percale, macaroni, a gag, a banana bag, a tan, a tag, a banana bag again (or a camel), a crepe, pins, Spam, a rut, a Rolo, cash, a jar, sore hats, a peon, a canal: Panama!"))

#reverse_string ('A man, a plan, a canoe, pasta, heros, rajahs, a coloratura, maps, snipe, percale, macaroni, a gag, a banana bag, a tan, a tag, a banana bag again (or a camel), a crepe, pins, Spam, a rut, a Rolo, cash, a jar, sore hats, a peon, a canal: Panama!',) {}

Of course the good thing with decorators is that you can use them right away on almost anything without rewriting. DRY, I said:

@counter
@benchmark
@logging
def get_random_futurama_quote():
    from urllib import urlopen
    result = urlopen("http://subfusion.net/cgi-bin/quote.pl?quote=futurama").read()
    try:
        value = result.split("<br><b><hr><br>")[1].split("<br><br><hr>")[0]
        return value.strip()
    except:
        return "No, I'm ... doesn't!"


print(get_random_futurama_quote())
print(get_random_futurama_quote())

#outputs:
#get_random_futurama_quote () {}
#wrapper 0.02
#wrapper has been used: 1x
#The laws of science be a harsh mistress.
#get_random_futurama_quote () {}
#wrapper 0.01
#wrapper has been used: 2x
#Curse you, merciful Poseidon!

Python itself provides several decorators: property, staticmethod, etc.

• Django uses decorators to manage caching and view permissions.
• Twisted to fake inlining asynchronous functions calls.

This really is a large playground.

Since you already had a running version of WAMP and it stopped working, you probably had VCRUNTIME140.dll already installed. In that case:

1. Open Programs and Features
2. Right-click on the respective Microsoft Visual C++ 20xx Redistributable installers and choose "Change"
3. Choose "Repair". Do this for both x86 and x64

This did the trick for me.

I'm resurrecting this because I was researching a non-JavaScript way to do this. I wasn't into the key handlers, and the CSS positioning stuff was causing tab ordering to break since CSS repositioning doesn't change tab order.

My solution is based on the response at https://stackoverflow.com/a/9491141.

The solution source is below. tabindex is used to correct tab behaviour of the hidden button, as well as aria-hidden to avoid having the button read out by screen readers / identified by assistive devices.

<form method="post" action="">
  <button type="submit" name="useraction" value="2nd" class="default-button-handler" aria-hidden="true" tabindex="-1"></button>
  <div class="form-group">
    <label for="test-input">Focus into this input: </label>
    <input type="text" id="test-input" class="form-control" name="test-input" placeholder="Focus in here and press enter / go" />
  </div>

1st button in DOM 2nd button in DOM 3rd button in DOM

Essential CSS for this solution:

.default-button-handler {
  width: 0;
  height: 0;
  padding: 0;
  border: 0;
  margin: 0;
}

Try this:

Replace:

audio.load();

with:

audio.play();

You can use the csv module to parse tab seperated value files easily.

import csv

with open("tab-separated-values") as tsv:
    for line in csv.reader(tsv, dialect="excel-tab"): #You can also use delimiter="\t" rather than giving a dialect.
        ... 

Where line is a list of the values on the current row for each iteration.

Edit: As suggested below, if you want to read by column, and not by row, then the best thing to do is use the zip() builtin:

with open("tab-separated-values") as tsv:
    for column in zip(*[line for line in csv.reader(tsv, dialect="excel-tab")]):
        ...

I'm not familiar with resolve, but I've used the others:

Recursive

Recursive is the default for non-fast-forward merges. We're all familiar with that one.

Octopus

I've used octopus when I've had several trees that needed to be merged. You see this in larger projects where many branches have had independent development and it's all ready to come together into a single head.

An octopus branch merges multiple heads in one commit as long as it can do it cleanly.

For illustration, imagine you have a project that has a master, and then three branches to merge in (call them a, b, and c).

A series of recursive merges would look like this (note that the first merge was a fast-forward, as I didn't force recursion):

However, a single octopus merge would look like this:

commit ae632e99ba0ccd0e9e06d09e8647659220d043b9
Merge: f51262e... c9ce629... aa0f25d...

Ours

Ours == I want to pull in another head, but throw away all of the changes that head introduces.

This keeps the history of a branch without any of the effects of the branch.

(Read: It is not even looked at the changes between those branches. The branches are just merged and nothing is done to the files. If you want to merge in the other branch and every time there is the question "our file version or their version" you can use git merge -X ours)

Subtree

Subtree is useful when you want to merge in another project into a subdirectory of your current project. Useful when you have a library you don't want to include as a submodule.

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

A C# version of Miroslav Zadravec's code

for (int i = 0; i < dataGridView1.Columns.Count-1; i++)
{
    dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
}
dataGridView1.Columns[dataGridView1.Columns.Count - 1].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
    int colw = dataGridView1.Columns[i].Width;
    dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
    dataGridView1.Columns[i].Width = colw;
}

One approach could be using find:

for directories

find /desired_location -type d -print0 | xargs -0 chmod 0755

for files

find /desired_location -type f -print0 | xargs -0 chmod 0644

There are several possible reasons for an error like this.

In my case, it was due to the executable file (docker-entrypoint.sh from the Ghost blog Dockerfile) lacking the executable file mode after I'd downloaded it.

Solution: chmod +x docker-entrypoint.sh

You could use the Fisher-Yates Shuffle (code adapted from this site):

function shuffle(array) {
    let counter = array.length;

    // While there are elements in the array
    while (counter > 0) {
        // Pick a random index
        let index = Math.floor(Math.random() * counter);

        // Decrease counter by 1
        counter--;

        // And swap the last element with it
        let temp = array[counter];
        array[counter] = array[index];
        array[index] = temp;
    }

    return array;
}

You may have found the answer for it already, but here is what I do.

I usually place this line at the beginning of my installation scripts:

if(!$PSScriptRoot){ $PSScriptRoot = Split-Path $MyInvocation.MyCommand.Path -Parent } #In case if $PSScriptRoot is empty (version of powershell V.2).  

Then I can use $PSScriptRoot variable as a location of the current script(path), like in the example bellow:

if(!$PSScriptRoot){ $PSScriptRoot = Split-Path $MyInvocation.MyCommand.Path -Parent } #In case if $PSScriptRoot is empty (version of powershell V.2).  

Try {
If (Test-Path 'C:\Program Files (x86)') {
    $ChromeInstallArgs= "/i", "$PSScriptRoot\googlechromestandaloneenterprise64_v.57.0.2987.110.msi", "/q", "/norestart", "/L*v `"C:\Windows\Logs\Google_Chrome_57.0.2987.110_Install_x64.log`""
    Start-Process -FilePath msiexec -ArgumentList $ChromeInstallArgs -Wait -ErrorAction Stop
    $Result= [System.Environment]::ExitCode
} Else {
    $ChromeInstallArgs= "/i", "$PSScriptRoot\googlechromestandaloneenterprise_v.57.0.2987.110.msi", "/q", "/norestart", "/L*v `"C:\Windows\Logs\Google_Chrome_57.0.2987.110_Install_x86.log`""
    Start-Process -FilePath msiexec -ArgumentList $ChromeInstallArgs -Wait -ErrorAction Stop
    $Result= [System.Environment]::ExitCode
    }

} ### End Try block


Catch  {
    $Result = [System.Environment]::Exitcode
    [System.Environment]::Exit($Result)
   }
[System.Environment]::Exit($Result)

In your case, you can replace

Start-process... line with

Invoke-Expression $PSScriptRoot\ScriptName.ps1

Question: Check whether a $_POST value is empty.

Translation: Check to see if an array key/index has a value associated with it.

Answer: Depends on your emphasis on security. Depends on what is allowed as valid input.

1. Some people say use empty().

From the PHP Manual:

"[Empty] determines whether a variable is considered to be empty. A variable is considered empty if it does not exist or if its value equals FALSE."

The following are thus considered empty.

"" (an empty string)
0 (0 as an integer)
0.0 (0 as a float)
"0" (0 as a string)
NULL
FALSE
array() (an empty array)
$var; (a variable declared, but without a value)

If none of these values are valid for your input control, then empty() would work. The problem here is that empty() might be too broad to be used consistently (the same way, for the same reason, on different input control submissions to $_POST or $_GET). A good use of empty() is to check if an entire array is empty (has no elements).

2. Some people say use isset().

isset() (a language construct) cannot operate on entire arrays, as in isset($myArray). It can only operate on variables and array elements (via the index/key): isset($var) and isset($_POST['username']). The isset()language construct does two things. First it checks to see if a variable or array index/key has a value associated with it. Second, it checks to make sure that value is not equal to the PHP NULL value.

In short, the most accurate check can be accomplished best with isset(), as some input controls do not even register with $_POST when they are not selected or checked. I have never known a form that submitted the PHP NULL value. None of mine do, so I use isset() to check if a $_POST key has no value associated with it (and that is not NULL). isset()is a much stricter test of emptiness (in the sense of your question) than empty().

3. Some people say just do if($var), if($myArray), or if($myArray['userName']) to determine emptiness.

You can test anything that evaluates to true or false in an if statement. Empty arrays evaluate to false and so do variables that are not set. Variables that contain the PHP NULL value also evaluate to false. Unfortunately in this case, like with empty(), many more things also evaluate to false: 1. the empty string '', zero (0), zero.zero (0.0), the string zero '0', boolean false, and certain empty XML objects.

--Doyle, Beginning PHP 5.3

In conclusion, use isset() and consider combining it with other tests. Example:

May not work due to superglobal screwiness, but would work for other arrays without question.

if (is_array($_POST) && !empty($_POST)) {
    // Now test for your successful controls in $_POST with isset()
} 

Hence, why look for a value associated with a key before you even know for sure that $_POST represents an array and has any values stored in it at all (something many people fail to consider)? Remember, people can send data to your form without using a web browser. You may one day get to the point of testing that $_POST only has the allowed keys, but that conversation is for another day.

shutil.copyfileobj       ?             ?                 ?           ?
??????????????????????????????????????????????????????????????????????????????

Example:

import shutil
shutil.copy('/etc/hostname', '/var/tmp/testhostname')

But still, the memory address for each letter in this address is different.

Memory address is different but as its array of characters they are sequential. When you pass address of first element and use %s, printf will print all characters starting from given address until it finds '\0'.

Here is a simple snippet that read's in a json text file from a dictionary. Note that your json file must follow the json standard, so it has to have " double quotes rather then ' single quotes.

Your JSON dump.txt File:

{"test":"1", "test2":123}

Python Script:

import json
with open('/your/path/to/a/dict/dump.txt') as handle:
    dictdump = json.loads(handle.read())

It seems to me, that slicing isn't so much a problem other than when your own classes and program are poorly architected/designed.

If I pass a subclass object in as a parameter to a method, which takes a parameter of type superclass, I should certainly be aware of that and know the internally, the called method will be working with the superclass (aka baseclass) object only.

It seems to me only the unreasonable expectation that providing a subclass where a baseclass is requested, would somehow result in subclass specific results, would cause slicing to be a problem. Its either poor design in the use of the method or a poor subclass implementation. I'm guessing its usually the result of sacrificing good OOP design in favor of expediency or performance gains.

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

you can also use use case/esac

case "$string" in
 "$pattern" ) echo "found";;
esac

You'll have to parse again if you want it in actual JSON:

JSON.parse(JSON.stringify(object))

this prototype:

  int execlp(const char *file, const char *arg, ...);

Says that execlp ìs a variable argument function. It takes 2 const char *. The rest of the arguments, if any, are the additional arguments to hand over to program we want to run - also char * - all these are C strings (and the last argument must be a NULL pointer)

So, the file argument is the path name of an executable file to be executed. arg is the string we want to appear as argv[0] in the executable. By convention, argv[0] is just the file name of the executable, normally it's set to the same as file.

The ... are now the additional arguments to give to the executable.

Say you run this from a commandline/shell:

$ ls

That'd be execlp("ls", "ls", (char *)NULL); Or if you run

$ ls -l /

That'd be execlp("ls", "ls", "-l", "/", (char *)NULL);

So on to execlp("/bin/sh", ..., "ls -l /bin/??", ...);

Here you are going to the shell, /bin/sh , and you're giving the shell a command to execute. That command is "ls -l /bin/??". You can run that manually from a commandline/shell:

 $ ls -l /bin/??

Now, how do you run a shell and tell it to execute a command ? You open up the documentation/man page for your shell and read it.

What you want to run is:

$ /bin/sh -c "ls -l /bin/??"

This becomes

  execlp("/bin/sh","/bin/sh", "-c", "ls -l /bin/??", (char *)NULL);

Side note: The /bin/?? is doing pattern matching, this pattern matching is done by the shell, and it expands to all files under /bin/ with 2 characters. If you simply did

  execlp("ls","ls", "-l", "/bin/??", (char *)NULL);

Probably nothing would happen (unless there's a file actually named /bin/??) as there's no shell that interprets and expands /bin/??

The solution was to call...

$scope.$apply();

...in my jQuery event callback.

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

As of kafka 2.3.0 version, there is an alternate way to soft deletion of Kafka (old approach are deprecated ).

Update retention.ms to 1 sec (1000ms) then set it again after a min, to default setting i.e 7 days (168 hours, 604,800,000 in ms )

Soft deletion:- (rentention.ms=1000) (using kafka-configs.sh)

bin/kafka-configs.sh --zookeeper 192.168.1.10:2181 --alter --entity-name kafka_topic3p3r --entity-type topics  --add-config retention.ms=1000
Completed Updating config for entity: topic 'kafka_topic3p3r'.

Setting to default:- 7 days (168 hours , retention.ms= 604800000)

bin/kafka-configs.sh --zookeeper 192.168.1.10:2181 --alter --entity-name kafka_topic3p3r --entity-type topics  --add-config retention.ms=604800000

update ubuntu:

 sudo apt-get update

Install rvm, which manages the ruby versions:

to install rvm use the following command.

 \curl -sSL https://get.rvm.io | bash -s stable

 rvm install ruby-2.1.4

Check ruby versions installed and in use:

rvm list
rvm use --default ruby-2.1.4

First, I would not recommend trying export Html and hope that the user's instance of Excel picks it up. My experience that this solution is fraught with problems including incompatibilities with Macintosh clients and throwing an error to the user that the file in question is not of the format specified. The most bullet-proof, user-friendly solution is a server-side one where you use a library to build an actual Excel file and send that back to the user. The next best solution and more universal solution would be to use the Open XML format. I've run into a few rare compatibility issues with older versions of Excel but on the whole this should give you a solution that will work on any version of Excel including Macs.

Open XML

The answer of crdunst is pretty neat and the best looking answer I've found but there's no explanation on how to use and the code is bigger than needed.

The only code you need:

#element {
    background-color: #cacbcf;
    text-shadow: 2px 2px 4px rgba(0,0,0, 0.5);
    filter: chroma(color=#cacbcf) progid:DXImageTransform.Microsoft.dropshadow(color=#60000000, offX=2, offY=2);
}

First you MUST specify a background-color - if your element should be transparent just copy the background-color of the parent or let it inherit. The color at the chroma-filter must match the background-color to fix those artifacts around the text (but here you must copy the color, you can't write inherit). Note that I haven't shortened the dropshadow-filter - it works but the shadows are then cut to the element dimensions (noticeable with big shadows; try to set the offsets to atleast 4).

TIP: If you want to use colors with transparency (alpha-channel) write in a #AARRGGBB notation, where AA stands for a hexadezimal value of the opacity - from 01 to FE, because FF and ironically also 00 means no transparency and is therefore useless.. ^^ Just go a little lower than in the rgba notation because the shadows aren't soft and the same alpha value would appear darker then. ;)

A nice snippet to convert the alpha value for IE (JavaScript, just paste into the console):

var number = 0.5; //alpha value from the rgba() notation
("0"+(Math.round(0.75 * number * 255).toString(16))).slice(-2);

ISSUES: The text/font behaves like an image after the shadow is applied; it gets pixelated and blurry after you zoom in... But that's IE's issue, not mine.

Live demo of the shadow here: http://jsfiddle.net/12khvfru/2/

The terms are somewhat interchangeable. The distinction described in other answers is more properly expressed with the terms formal parameter for the name used inside the body of the function and parameter for the value supplied at the call site (formal argument and argument are also common).

Also note that, in mathematics, the term argument is far more common and parameter usually means something quite different (though the parameter in a parametric equation is essentially the argument to two or more functions).

After trying the other suggestions to no avail I discovered that this issue was related to styling for me. I don't know a lot about the why but I found that my SVGs were not visible because they were not holding their place in the DOM.

In essence, the containers around my SVGs were at width: 0 and overflow: hidden.

I fixed this by setting a width on the containers but it is possible that there is a more direct solution to that particular issue.

36, and the GUID will only use 0-9A-F (hexidecimal!).

12345678-1234-1234-1234-123456789012

That's 36 characters in any GUID--they are of constant length. You can read a bit more about the intricacies of GUIDs here.

You will need two more in length if you want to store the braces.

Note: 36 is the string length with the dashes in between. They are actually 16-byte numbers.

I have reviewed all the answers. I think in database insertion should be like:

ID     Name      SomeColumn
1.     ABC       ,X,Y Z (these are three different rows)
2.     MNO       ,R,S

The comma should be at previous end and do searching by like %,X,%

At first see this question to see how you can find if a link has a jQuery handler assigned to it.

Next use:

$("a").attr("onclick")

to see if there is a javascript event assigned to it.

If any of the above is true, then call the click method. If not, get the link:

$("a").attr("href")

and follow it.

I am afraid I don't know what to do if addEventListener is used to add an event handler. If you are in charge of the full page source, use only jQuery event handlers.

I would ensure all containers are docker-compose'd to the same network by composing them together at the same time, using:

docker compose --file ~/front/docker-compose.yml --file ~/api/docker-compose.yml up -d

It really depends on the kind of classes as not all classes are created equal.

As general guideline I would suggest 2 options:

• For value & immutable classes (Exception, Integer, DTOs and such) use single primary constructor as suggested in above answer
• For everything else (session beans, services, mutable objects, JPA & JAXB entities and so on) use default constructor only with sensible defaults on all the properties so it can be used without additional configuration

The solution I found was to use the New-Object cmdlet to initialize an array of the proper size.

$array = new-object object[] 5 
for($i=0; $i -lt $array.Length;$i++)
{
    $array[$i] = $FALSE
}

As far as I know, F11 or F12 doesn't work, and nor does Right Ctrl + F12.

Hit Left Ctrl + F12, or Home, or PageUp, (not NUMPAD 7 or NUMPAD 9 like the website says) to rotate the emulator.

http://developer.android.com/google/play-services/setup.html

Quoting docs

If you want to test your app on the emulator, expand the directory for Android 4.2.2 (API 17) or a higher version, select Google APIs, and install it. Then create a new AVD with Google APIs as the platform target.

I prefer testing on a real device which has google play services installed

It's a new feature called Modules or "semantic import". There's more info in the WWDC 2013 videos for Session 205 and 404. It's kind of a better implementation of the pre-compiled headers. You can use modules with any of the system frameworks in iOS 7 and Mavericks. Modules are a packaging together of the framework executable and its headers and are touted as being safer and more efficient than #import.

One of the big advantages of using @import is that you don't need to add the framework in the project settings, it's done automatically. That means that you can skip the step where you click the plus button and search for the framework (golden toolbox), then move it to the "Frameworks" group. It will save many developers from the cryptic "Linker error" messages.

You don't actually need to use the @import keyword. If you opt-in to using modules, all #import and #include directives are mapped to use @import automatically. That means that you don't have to change your source code (or the source code of libraries that you download from elsewhere). Supposedly using modules improves the build performance too, especially if you haven't been using PCHs well or if your project has many small source files.

Modules are pre-built for most Apple frameworks (UIKit, MapKit, GameKit, etc). You can use them with frameworks you create yourself: they are created automatically if you create a Swift framework in Xcode, and you can manually create a ".modulemap" file yourself for any Apple or 3rd-party library.

You can use code-completion to see the list of available frameworks:

Modules are enabled by default in new projects in Xcode 5. To enable them in an older project, go into your project build settings, search for "Modules" and set "Enable Modules" to "YES". The "Link Frameworks" should be "YES" too:

You have to be using Xcode 5 and the iOS 7 or Mavericks SDK, but you can still release for older OSs (say iOS 4.3 or whatever). Modules don't change how your code is built or any of the source code.

From the WWDC slides:

• Imports complete semantic description of a framework
• Doesn't need to parse the headers
• Better way to import a framework’s interface
• Loads binary representation
• More flexible than precompiled headers
• Immune to effects of local macro definitions (e.g. #define readonly 0x01)
• Enabled for new projects by default

To explicitly use modules:

Replace #import <Cocoa/Cocoa.h> with @import Cocoa;

You can also import just one header with this notation:

@import iAd.ADBannerView;

The submodules autocomplete for you in Xcode.

TortoiseSVN contains a console svn client, but by default the corresponding option is not enabled during installation.

The svn.exe executable is not standalone and it depends on some other files in the distribution but this should not be a problem in most cases.

Once installed you might need to add the folder containing svn.exe to the system PATH as described here so that it is available in your console. To check if it was already added by the installer open a new console and type echo %PATH%. Use set on its own to see all environmental variables.

I had issues with subtrees and submodules that the other answers suggest... mainly because I am using SourceTree and it seems fairly buggy.

Instead, I ended up using SymLinks and that seems to work well so I am posting it here as a possible alternative.

There is a complete guide here: http://www.howtogeek.com/howto/16226/complete-guide-to-symbolic-links-symlinks-on-windows-or-linux/

But basically you just need to mklink the two paths in an elevated command prompt. Make sure you use the /J hard link prefix. Something along these lines: mklink /J C:\projects\MainProject\plugins C:\projects\SomePlugin

You can also use relative folder paths and put it in a bat to be executed by each person when they first check out your project.

Example: mklink /J .\Assets\TaqtileTools ..\TaqtileHoloTools

Once the folder has been linked you may need to ignore the folder within your main repository that is referencing it. Otherwise you are good to go.

Note I've deleted my duplicate answer from another post as that post was marked as a duplicate question to this one.

For everyone else who has no duplicate Listen directives and no running processes on the port: check that you don't accidentally include ports.conf twice in apache2.conf (as I did due to a bad merge).

It was changing the line endings (from Windows CRLF to Unix LF) in the .htaccess file that fixed it for me.

Just run

docker restart $(docker ps -q)

Update

For Docker 1.13.1 use docker restart $(docker ps -a -q) as in answer lower.

Maybe useful (Powershell)

http://sbrennan.net/2012/10/21/configuring-application-crash-dumps-with-powershell/

From Windows Vista and Windows Server 2008 onwards Microsoft introduced Windows Error Reporting or WER . This allows the server to be configured to automatically enable the generation and capture of Application Crash dumps. The configuration of this is discussed here . The main problem with the default configuration is the dump files are created and stored in the %APPDATA%\crashdumps folder running the process which can make it awkward to collect dumps as they are spread all over the server. There are additional problems with this as but the main problem I always had with it was that its a simple task that is very repetitive but easy to do incorrectly.

Source code in Powershell (should be useful source code in C# too):

$verifydumpkey = Test-Path "HKLM:\Software\Microsoft\windows\Windows Error Reporting\LocalDumps"
 
    if ($verifydumpkey -eq $false )
    {
    New-Item -Path "HKLM:\Software\Microsoft\windows\Windows Error Reporting\" -Name LocalDumps
    }
 
##### adding the values
 
$dumpkey = "HKLM:\Software\Microsoft\Windows\Windows Error Reporting\LocalDumps"
 
New-ItemProperty $dumpkey -Name "DumpFolder" -Value $Folder -PropertyType "ExpandString" -Force
New-ItemProperty $dumpkey -Name "DumpCount" -Value 10 -PropertyType "Dword" -Force
New-ItemProperty $dumpkey -Name "DumpType" -Value 2 -PropertyType "Dword" -Force

Since the general guideline in Python is to ask for forgiveness rather than permission, I think the most pythonic way to detect a string/scalar from a sequence is to check if it contains an integer:

try:
    1 in a
    print('{} is a sequence'.format(a))
except TypeError:
    print('{} is a scalar or string'.format(a))

Interface : should be used if you want to imply a rule on the components which may or may not be related to each other

Pros:

1. Allows multiple inheritance
2. Provides abstraction by not exposing what exact kind of object is being used in the context
3. provides consistency by a specific signature of the contract

Cons:

1. Must implement all the contracts defined
2. Cannot have variables or delegates
3. Once defined cannot be changed without breaking all the classes

Abstract Class : should be used where you want to have some basic or default behaviour or implementation for components related to each other

Pros:

1. Faster than interface
2. Has flexibility in the implementation (you can implement it fully or partially)
3. Can be easily changed without breaking the derived classes

Cons:

1. Cannot be instantiated
2. Does not support multiple inheritance

If You Have Multiple li elements inside an li element then this will definitely help you, and i have checked it and it works....

<script>
$("li").on('click', function() {
          alert(this.id);
          return false;
      });
</script>

You can invoke dll function from user32.dll i think Something like

Rundll32.exe user32.dll, MessageBox (0, "text", "titleText", {extra flags for like topmost messagebox e.t.c})

Typing it from my Phone, don't judge me... otherwise i would link the extra flags.

How does it work?

When a JSF view (Facelets/JSP file) get built/restored, a JSF component tree will be produced. At that moment, the view build time, all binding attributes are evaluated (along with id attribtues and taghandlers like JSTL). When the JSF component needs to be created before being added to the component tree, JSF will check if the binding attribute returns a precreated component (i.e. non-null) and if so, then use it. If it's not precreated, then JSF will autocreate the component "the usual way" and invoke the setter behind binding attribute with the autocreated component instance as argument.

In effects, it binds a reference of the component instance in the component tree to a scoped variable. This information is in no way visible in the generated HTML representation of the component itself. This information is in no means relevant to the generated HTML output anyway. When the form is submitted and the view is restored, the JSF component tree is just rebuilt from scratch and all binding attributes will just be re-evaluated like described in above paragraph. After the component tree is recreated, JSF will restore the JSF view state into the component tree.

Component instances are request scoped!

Important to know and understand is that the concrete component instances are effectively request scoped. They're newly created on every request and their properties are filled with values from JSF view state during restore view phase. So, if you bind the component to a property of a backing bean, then the backing bean should absolutely not be in a broader scope than the request scope. See also JSF 2.0 specitication chapter 3.1.5:

3.1.5 Component Bindings

...

Component bindings are often used in conjunction with JavaBeans that are dynamically instantiated via the Managed Bean Creation facility (see Section 5.8.1 “VariableResolver and the Default VariableResolver”). It is strongly recommend that application developers place managed beans that are pointed at by component binding expressions in “request” scope. This is because placing it in session or application scope would require thread-safety, since UIComponent instances depends on running inside of a single thread. There are also potentially negative impacts on memory management when placing a component binding in “session” scope.

Otherwise, component instances are shared among multiple requests, possibly resulting in "duplicate component ID" errors and "weird" behaviors because validators, converters and listeners declared in the view are re-attached to the existing component instance from previous request(s). The symptoms are clear: they are executed multiple times, one time more with each request within the same scope as the component is been bound to.

And, under heavy load (i.e. when multiple different HTTP requests (threads) access and manipulate the very same component instance at the same time), you may face sooner or later an application crash with e.g. Stuck thread at UIComponent.popComponentFromEL, or Java Threads at 100% CPU utilization using richfaces UIDataAdaptorBase and its internal HashMap, or even some "strange" IndexOutOfBoundsException or ConcurrentModificationException coming straight from JSF implementation source code while JSF is busy saving or restoring the view state (i.e. the stack trace indicates saveState() or restoreState() methods and like).

Using binding on a bean property is bad practice

Regardless, using binding this way, binding a whole component instance to a bean property, even on a request scoped bean, is in JSF 2.x a rather rare use case and generally not the best practice. It indicates a design smell. You normally declare components in the view side and bind their runtime attributes like value, and perhaps others like styleClass, disabled, rendered, etc, to normal bean properties. Then, you just manipulate exactly that bean property you want instead of grabbing the whole component and calling the setter method associated with the attribute.

In cases when a component needs to be "dynamically built" based on a static model, better is to use view build time tags like JSTL, if necessary in a tag file, instead of createComponent(), new SomeComponent(), getChildren().add() and what not. See also How to refactor snippet of old JSP to some JSF equivalent?

Or, if a component needs to be "dynamically rendered" based on a dynamic model, then just use an iterator component (<ui:repeat>, <h:dataTable>, etc). See also How to dynamically add JSF components.

Composite components is a completely different story. It's completely legit to bind components inside a <cc:implementation> to the backing component (i.e. the component identified by <cc:interface componentType>. See also a.o. Split java.util.Date over two h:inputText fields representing hour and minute with f:convertDateTime and How to implement a dynamic list with a JSF 2.0 Composite Component?

Only use binding in local scope

However, sometimes you'd like to know about the state of a different component from inside a particular component, more than often in use cases related to action/value dependent validation. For that, the binding attribute can be used, but not in combination with a bean property. You can just specify an in the local EL scope unique variable name in the binding attribute like so binding="#{foo}" and the component is during render response elsewhere in the same view directly as UIComponent reference available by #{foo}. Here are several related questions where such a solution is been used in the answer:

• Validate input as required only if certain command button is pressed
• How to render a component only if another component is not rendered?
• JSF 2 dataTable row index without dataModel
• Primefaces dependent selectOneMenu and required="true"
• Validate a group of fields as required when at least one of them is filled
• How to change css class for the inputfield and label when validation fails?
• Getting JSF-defined component with Javascript

• Use an EL expression to pass a component ID to a composite component in JSF

  (and that's only from the last month...)

See also:

• How to use component binding in JSF right ? (request-scoped component in session scoped bean)
• View scope: java.io.NotSerializableException: javax.faces.component.html.HtmlInputText
• Binding attribute causes duplicate component ID found in the view

In Java 1.4 and up:

String input = "...";
Matcher matcher = Pattern.compile("[^0-9]+([0-9]+)[^0-9]+").matcher(input);
if (matcher.find()) {
    String someNumberStr = matcher.group(1);
    // if you need this to be an int:
    int someNumberInt = Integer.parseInt(someNumberStr);
}

It looks like SyndFeed is not using generics.

You could either have an unsafe cast and a warning suppression:

@SuppressWarnings("unchecked")
List<SyndEntry> entries = (List<SyndEntry>) sf.getEntries();

or call Collections.checkedList - although you'll still need to suppress the warning:

@SuppressWarnings("unchecked")
List<SyndEntry> entries = Collections.checkedList(sf.getEntries(), SyndEntry.class);

What Dragan B suggested is right way to go for Bootstrap 4. I have put one example below. e.g. mr-3 is margin-right:1rem!important

<div class="btn-toolbar pull-right">
   <button type="button" class="btn mr-3">btn1</button>
   <button type="button" class="btn mr-3">btn2</button>
   <button type="button" class="btn">btn3</button>
</div>

p.s: in my case I wanted my buttons to be displayed to the right of the screen and hence pull-right.

You should be able to do something like:

ArrayList<String> list = new ArrayList<String>();
for( String s : foo )
{
    list.add(s);
}

>>>def random_char(y):
       return ''.join(random.choice(string.ascii_letters) for x in range(y))

>>>print (random_char(5))
>>>fxkea

to generate y number of random characters

To my mind the case for a PT (as @Nathan Fisher) is a 'no brainer', but I would add a column to facilitate ordering by rank (up or down):

OPS is entered as VALUES (Sum of) twice so I have renamed the column labels to make clearer which is which. The PT is in a different sheet from the data but could be in the same sheet.

Rank is set with a right click on a data point selected in that column and Show Values As... and Rank Largest to Smallest (there are other options) with the Base field as Player and the filter is a Value Filters, Top 10... one:

Once in a PT the power of that feature can very easily be applied to view the data in many other ways, with no change of formula (there isn't one!).

In the case of a tie for the last position included in the filter both results are included (Top 5 would show six or more results). A tie for top rank between just two players would show as 1 1 3 4 5 for Top 5.

This suffices and stores the first line of filename in the variable $line:

read -r line < filename

I also like awk for this:

awk 'NR==1 {print; exit}' file

To store the line itself, use the var=$(command) syntax. In this case, line=$(awk 'NR==1 {print; exit}' file).

Or even sed:

sed -n '1p' file

With the equivalent line=$(sed -n '1p' file).

See a sample when we feed the read with seq 10, that is, a sequence of numbers from 1 to 10:

$ read -r line < <(seq 10) 
$ echo "$line"
1

$ line=$(awk 'NR==1 {print; exit}' <(seq 10))
$ echo "$line"
1

Try something like this:

$(function(){
  $('input[type="radio"]').click(function(){
    if ($(this).is(':checked'))
    {
      alert($(this).val());
    }
  });
});

If you give your radio buttons a class then you can replace the code $('input[type="radio"]') with $('.someclass').

I found a solution here PDFLayoutTextStripper

It's good because it can keep the layout of the original PDF.

It's written in Java but I have added a Gateway to support Python.

Sample code:

from py4j.java_gateway import JavaGateway

gw = JavaGateway()
result = gw.entry_point.strip('samples/bus.pdf')

# result is a dict of {
#   'success': 'true' or 'false',
#   'payload': pdf file content if 'success' is 'true'
#   'error': error message if 'success' is 'false'
# }

print result['payload']

Sample output from PDFLayoutTextStripper:

You can see more details here Stripper with Python

To handle sortable list in Framework7 when user release currently sorting element in new position, you can use this code:

  $$('li').on('sortable:sort',function(event){

The best way is to copy all the files and folders inside a directory on your local file system by: docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH

SRC_PATH is on container DEST_PATH is on localhost

Then do docker-compose down attach a volume to the same DEST_PATH and run Docker containers by using docker-compose up -d

Add volume by following in docker-compose.yml

volumes:
 - DEST_PATH:SRC_PATH

It's possible using jQuery it depends on your site load time you can adjust your timeout. It can be your custom image or you can use youtube image maxres1.jpg, maxres2.jpg or maxres3.jpg

var newImage = 'http://i.ytimg.com/vi/[Video_ID]/maxres1.jpg';
window.setTimeout(function() {
jQuery('div > div.video-container-thumb > div > a > img').attr('src',newImage );

pandas.isnull() (also pd.isna(), in newer versions) checks for missing values in both numeric and string/object arrays. From the documentation, it checks for:

NaN in numeric arrays, None/NaN in object arrays

Quick example:

import pandas as pd
import numpy as np
s = pd.Series(['apple', np.nan, 'banana'])
pd.isnull(s)
Out[9]: 
0    False
1     True
2    False
dtype: bool

The idea of using numpy.nan to represent missing values is something that pandas introduced, which is why pandas has the tools to deal with it.

Datetimes too (if you use pd.NaT you won't need to specify the dtype)

In [24]: s = Series([Timestamp('20130101'),np.nan,Timestamp('20130102 9:30')],dtype='M8[ns]')

In [25]: s
Out[25]: 
0   2013-01-01 00:00:00
1                   NaT
2   2013-01-02 09:30:00
dtype: datetime64[ns]``

In [26]: pd.isnull(s)
Out[26]: 
0    False
1     True
2    False
dtype: bool

try using begin.startOf('isoWeek'); instead of begin.startOf('week');

This worked for me in Bootstrap 4 since it has different breakpoints than v3:

@media (min-width: 992px) {
    .table-responsive {
        overflow: inherit;
    }
}

In newer versions(>=1.8.0) of docker, you can do this

docker build -f Dockerfile.db .
docker build -f Dockerfile.web .

A big save.

EDIT: update versions per raksja's comment

EDIT: comment from @vsevolod: it's possible to get syntax highlighting in VS code by giving files .Dockerfile extension(instead of name) e.g. Prod.Dockerfile, Test.Dockerfile etc.

Using setInterval or setTimeout

You should pass a reference to a function as the first argument for setTimeout or setInterval. This reference may be in the form of:

• An anonymous function

  setTimeout(function(){/* Look mah! No name! */},2000);
  

• A name of an existing function

  function foo(){...}
  
  setTimeout(foo, 2000);
  

• A variable that points to an existing function

  var foo = function(){...};
  
  setTimeout(foo, 2000);
  

  _{Do note that I set "variable in a function" separately from "function name". It's not apparent that variables and function names occupy the same namespace and can clobber each other.}

Passing arguments

To call a function and pass parameters, you can call the function inside the callback assigned to the timer:

setTimeout(function(){
  foo(arg1, arg2, ...argN);
}, 1000);

There is another method to pass in arguments into the handler, however it's not cross-browser compatible.

setTimeout(foo, 2000, arg1, arg2, ...argN);

Callback context

By default, the context of the callback (the value of this inside the function called by the timer) when executed is the global object window. Should you want to change it, use bind.

setTimeout(function(){
  this === YOUR_CONTEXT; // true
}.bind(YOUR_CONTEXT), 2000);

Security

Although it's possible, you should not pass a string to setTimeout or setInterval. Passing a string makes setTimeout() or setInterval() use a functionality similar to eval() that executes strings as scripts, making arbitrary and potentially harmful script execution possible.

You should add Apache Mahout to your shopping list.

The parameters of isset() should be separated by a comma sign (,) and not a dot sign (.). Your current code concatenates the variables into a single parameter, instead of passing them as separate parameters.

So the original code evaluates the variables as a unified string value:

isset($_POST['search_term'] . $_POST['postcode']) // Incorrect

While the correct form evaluates them separately as variables:

isset($_POST['search_term'], $_POST['postcode']) // Correct

Use ChangeDetectorRef.detectChanges() to tell Angular to run a change detection when you edit a nested object (that it misses with its dirty checking).

I think that. When guest is launching page, but Admin is not logged in we don`t show something, for example the Chat.

add_action('init', 'chat_status');

function chat_status(){

    if( get_option('admin_logged') === 1) { echo "<style>.chat{display:block;}</style>";}
        else { echo "<style>.chat{display:none;}</style>";}

}



add_action('wp_login', function(){

    if( wp_get_current_user()->roles[0] == 'administrator' ) update_option('admin_logged', 1);
});


add_action('wp_logout', function(){
    if( wp_get_current_user()->roles[0] == 'administrator' ) update_option('admin_logged', 0);
});

On Windows it ended up being that the port was already in use by IIS.

Stopping IIS (Right-click, Exit), resolved the issue.

I have try this my new code and it might be helpful to you, it works perfectly in google chromr

hr {
     color: #f00;
     background: #f00; 
     width: 75%; 
     height: 5px;
}

To add bold, italic and underline, just add the following to the font argument:

font=("Arial", 8, 'normal', 'bold', 'italic', 'underline')

You should assign setTimeout to a variable and use clearTimeout to clear it on keypress.

var timer = '';

$('input#username').keypress(function() {
  clearTimeout(timer);
  timer = setTimeout(function() {
    //Your code here
  }, 3000); //Waits for 3 seconds after last keypress to execute the above lines of code
});

Fiddle

Hope this helps.

The problem is that your regex is a string, but html is bytes:

>>> type(html)
<class 'bytes'>

Since python doesn't know how those bytes are encoded, it throws an exception when you try to use a string regex on them.

You can either decode the bytes to a string:

html = html.decode('ISO-8859-1')  # encoding may vary!
title = re.findall(pattern, html)  # no more error

Or use a bytes regex:

regex = rb'<title>(,+?)</title>'
#        ^

In this particular context, you can get the encoding from the response headers:

with urllib.request.urlopen(url) as response:
    encoding = response.info().get_param('charset', 'utf8')
    html = response.read().decode(encoding)

See the urlopen documentation for more details.

You need to get ObjectNode type object in order to set values. Take a look at this

What you actually created with:

MyType[] list = []

Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:

MyType[] array = new MyType[4]

But there's no add method of course.

If you create list with def it's something like creating this instance with Object (You can read more about def here). And [] creates empty ArrayList in this case.

So using def list = [] you can then append new items with add() method of ArrayList

list.add(new MyType())

Or more groovy way with overloaded left shift operator:

list << new MyType() 

Simply last would work here:

for my $entry (@array){
    if ($string eq "text"){
         last;
    }
}

If you have nested loops, then last will exit from the innermost loop. Use labels in this case:

LBL_SCORE: {
    for my $entry1 (@array1) {
        for my $entry2 (@array2) {
            if ($entry1 eq $entry2) { # Or any condition
                last LBL_SCORE;
            }
        }
    }
 }

Given a last statement will make the compiler to come out from both the loops. The same can be done in any number of loops, and labels can be fixed anywhere.

As for the question which event you should use for this: use the input event, and fall back to keyup/keydown in older browsers.

Here’s an example, DOM0-style:

someElement.oninput = function() {
  this.onkeydown = null;
  // Your code goes here
};
someElement.onkeydown = function() {
  // Your code goes here
};

The other question is how to count the number of characters in the string. Depending on your definition of “character”, all answers posted so far are incorrect. The string.length answer is only reliable when you’re certain that only BMP Unicode symbols will be entered. For example, 'a'.length == 1, as you’d expect.

However, for supplementary (non-BMP) symbols, things are a bit different. For example, ''.length == 2, even though there’s only one Unicode symbol there. This is because JavaScript exposes UCS-2 code units as “characters”.

Luckily, it’s still possible to count the number of Unicode symbols in a JavaScript string through some hackery. You could use Punycode.js’s utility functions to convert between UCS-2 strings and Unicode code points for this:

// `String.length` replacement that only counts full Unicode characters
punycode.ucs2.decode('a').length; // 1
punycode.ucs2.decode('').length; // 1 (note that `''.length == 2`!)

P.S. I just noticed the counter script that Stack Overflow uses gets this wrong. Try entering , and you’ll see that it (incorrectly) counts as two characters.

a = np.empty(0)
for x in y:
    a = np.append(a, x)

You can get the maximum like this:

>>> import pandas as pd
>>> df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
>>> df
   A  B
0  1 -2
1  2  8
2  3  1
>>> df[["A", "B"]]
   A  B
0  1 -2
1  2  8
2  3  1
>>> df[["A", "B"]].max(axis=1)
0    1
1    8
2    3

and so:

>>> df["C"] = df[["A", "B"]].max(axis=1)
>>> df
   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3

If you know that "A" and "B" are the only columns, you could even get away with

>>> df["C"] = df.max(axis=1)

And you could use .apply(max, axis=1) too, I guess.

Workaround is to hide the backdrop entirely if you don't need one like this: data-backdrop=""

<div class="modal fade preview-modal" data-backdrop="" id="preview-modal"  role="dialog" aria-labelledby="preview-modal" aria-hidden="true">

The dict.items iterates over the key-value pairs of a dictionary. Therefore for key, value in dictionary.items() will loop over each pair. This is documented information and you can check it out in the official web page, or even easier, open a python console and type help(dict.items). And now, just as an example:

>>> d = {'hello': 34, 'world': 2999}
>>> for key, value in d.items():
...   print key, value
...
world 2999
hello 34

The AttributeError is an exception thrown when an object does not have the attribute you tried to access. The class dict does not have any predictors attribute (now you know where to check it :) ), and therefore it complains when you try to access it. As easy as that.

Used implementation 'androidx.appcompat:appcompat:1.1.2' in App gradle fixed the issue for me

I had midnight issues in Word and the below code worked for me

Public Function Pause(NumberOfSeconds As Variant)
 '   On Error GoTo Error_GoTo

    Dim PauseTime, Start
    Dim objWord As Word.Document

    'PauseTime = 10 ' Set duration in seconds
    PauseTime = NumberOfSeconds
    Start = Timer ' Set start time.

    If Start + PauseTime > 86399 Then 'playing safe hence 86399

    Start = 0

    Do While Timer > 1
        DoEvents ' Yield to other processes.
    Loop

    End If

    Do While Timer < Start + PauseTime
        DoEvents ' Yield to other processes.
    Loop

There are several answers here but none of them satisfied my below requirements:

1. I don't want to wait for command to finish or pollute my terminal with subprocess outputs.

2. I want to run bash script with redirects.

3. I want to support piping within my bash script (for example find ... | tar ...).

The only combination that satiesfies above requirements is:

subprocess.Popen(['./my_script.sh "arg1" > "redirect/path/to"'],
                 stdout=subprocess.PIPE, 
                 stderr=subprocess.PIPE,
                 shell=True)

Why not Try EFS PhP-ZiP MultiVolume Script ... I zipped and transferred hundreds of gigs and millions of files ... ssh is needed to effectively create archives.

But i belive that resulting files can be used with exec directly from php:

exec('zip -r backup-2013-03-30_0 . -i@backup-2013-03-30_0.txt');

I do not know if it works. I have not tried ...

"the secret" is that the execution time for archiving should not exceed the time allowed for execution of PHP code.

I know the perfect answer:

1. double click on The password TextBox.
2. write your textbox name like textbox2.
3. write PasswordChar = '*';.

4. I prefer going to windows character map and find a perfect hide like ?.

   example:TextBox2.PasswordChar = '?';
   

In short, decoupling success callback function from the ajax function so later you can add your own handlers without modifying the original code (observer pattern).

Please find more detailed information from here: https://stackoverflow.com/a/14754681/1049184

Register the EventEmitter in your child component as the @Output:

@Output() onDatePicked = new EventEmitter<any>();

Emit value on click:

public pickDate(date: any): void {
    this.onDatePicked.emit(date);
}

Listen for the events in your parent component's template:

<div>
    <calendar (onDatePicked)="doSomething($event)"></calendar>
</div>

and in the parent component:

public doSomething(date: any):void {
    console.log('Picked date: ', date);
}

It's also well explained in the official docs: Component interaction.

You need to tell it which index in data to use, or double loop through all.

E.g., to get the values in the 4th index in the outside array.:

foreach($user->data[3]->values as $values)
{
     echo $values->value . "\n";
}

To go through all:

foreach($user->data as $mydata)
{
    foreach($mydata->values as $values) {
        echo $values->value . "\n";
    }

}   

You can write like this.

import java.util.Scanner;
class   BigNoArray{

    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter how many array element");
        int n=sc.nextInt();
        int[] ar= new int[n];
        System.out.println("enter "+n+" values");
        for(int i=0;i<ar.length;i++){
            ar[i]=sc.nextInt();
        }
        int fbig=ar[0];
        int sbig=ar[1];
        int tbig=ar[3];
            for(int i=1;i<ar.length;i++){
                if(fbig<ar[i]){
                    sbig=fbig;
                    fbig=ar[i];
                }
                else if(sbig<ar[i]&&ar[i]!=fbig){
                    sbig=ar[i];
                }
                else if(tbig<ar[i]&&ar[i]!=fbig){
                    tbig=ar[i];
                }
            }
        System.out.println("first big number is "+fbig);
        System.out.println("second big number is "+sbig);
        System.out.println("third big number is "+tbig);
    }
}

Just use append:

list1 = [1, 2, 3, 4, 5]
list2 = [123, 234, 456]
d = {'a': [], 'b': []}
d['a'].append(list1)
d['a'].append(list2)
print d['a']

Alternatively, you could use text stroke, which only works in webkit:

-webkit-text-stroke-width: 2px;
-webkit-text-stroke-color: #fff;

body {_x000D_

h1 {_x000D_
  -webkit-text-stroke-width: 2px;_x000D_
-webkit-text-stroke-color: #fff;_x000D_
}

The problem is that you thought your jsonString is a dictionary. It's not.

It's an array of dictionaries. In raw json strings, arrays begin with [ and dictionaries begin with {.

I used your json string with below code :

let string = "[{\"form_id\":3465,\"canonical_name\":\"df_SAWERQ\",\"form_name\":\"Activity 4 with Images\",\"form_desc\":null}]"
let data = string.data(using: .utf8)!
do {
    if let jsonArray = try JSONSerialization.jsonObject(with: data, options : .allowFragments) as? [Dictionary<String,Any>]
    {
       print(jsonArray) // use the json here     
    } else {
        print("bad json")
    }
} catch let error as NSError {
    print(error)
}

and I am getting the output :

[["form_desc": <null>, "form_name": Activity 4 with Images, "canonical_name": df_SAWERQ, "form_id": 3465]]

All the answers here use the jQuery library.

But the vanilla javascript is very straightforward.

If you want to run a script only if the element with an id of #dataTable also has a data-timer attribute, then the steps are as follows:

// Locate the element
const myElement = document.getElementById('dataTable');

// Run conditional code
if (myElement.dataset.hasOwnProperty('timer')) {

}

I highly recommend you to use ViewStubs like this

<FrameLayout
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="1" >

    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

    <ViewStub
        android:id="@android:id/empty"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout="@layout/empty" />
</FrameLayout>

If you look at the Console class in .NET Reflector, you'll find that if a process doesn't have an associated console, Console.Out and Console.Error are backed by Stream.Null (wrapped inside a TextWriter), which is a dummy implementation of Stream that basically ignores all input, and gives no output.

So it is conceptually equivalent to /dev/null, but the implementation is more streamlined: there's no actual I/O taking place with the null device.

Also, apart from calling SetOut, there is no way to configure the default.

Update 2020-11-02: As this answer is still gathering votes in 2020, it should probably be noted that under ASP.NET Core, there usually is a console attached. You can configure the ASP.NET Core IIS Module to redirect all stdout and stderr output to a log file via the stdoutLogEnabled and stdoutLogFile settings:

<system.webServer>
  <aspNetCore processPath="dotnet"
              arguments=".\MyApp.dll"
              hostingModel="inprocess"
              stdoutLogEnabled="true"
              stdoutLogFile=".\logs\stdout" />
<system.webServer>

In addition to all the answers, make sure you're not using your phone as a USB storage.

I was having the same problem on HTC Sensation on USB storage mode enabled. I can still debug/run the app, but I can't save to external storage.

I ran into the same problem. Placing a forward slash after the folder name worked for me.

ex: git add foldername/

Adding a right JRE System through build path is the solution but your eclipse still may have the error. To solve that go to Java Build path --> Order and Export and move your JRE system library on the top. This has solved my problem.

Check Inside the Following Directory for the jar file el-api.jar :C:\apache-tomcat-7.0.39\lib\el-api.jar if it exists then in this directory of your web application WEB-INF\lib\el-api.jar the jar should be removed

This could be a good time to mention the modr() function. It returns both the whole and the remainder parts of a division.

print("\n 17 // 3 =",17//3," # Does the same thing as int(17/3)")
print(" 17 %  3 =",17%3," # Modulo division gives the remainder.")
whole, remain = divmod(17,3)
print(" divmod(17,3) returns ->",divmod(17,3),end="")
print(" because 3 goes into 17,",whole,"times with a remainder of",remain,end=".\n\n")

Java 8 provides different utility api methods to help us sort the streams better.

If your list is a list of Integers(or Double, Long, String etc.,) then you can simply sort the list with default comparators provided by java.

List<Integer> integerList = Arrays.asList(1, 4, 3, 4, 5);

Creating comparator on fly:

integerList.stream().sorted((i1, i2) -> i1.compareTo(i2)).forEach(System.out::println);

With default comparator provided by java 8 when no argument passed to sorted():

integerList.stream().sorted().forEach(System.out::println); //Natural order

If you want to sort the same list in reverse order:

 integerList.stream().sorted(Comparator.reverseOrder()).forEach(System.out::println); // Reverse Order

If your list is a list of user defined objects, then:

List<Person> personList = Arrays.asList(new Person(1000, "First", 25, 30000),
        new Person(2000, "Second", 30, 45000),
        new Person(3000, "Third", 35, 25000));

Creating comparator on fly:

personList.stream().sorted((p1, p2) -> ((Long)p1.getPersonId()).compareTo(p2.getPersonId()))
        .forEach(person -> System.out.println(person.getName()));

Using Comparator.comparingLong() method(We have comparingDouble(), comparingInt() methods too):

personList.stream().sorted(Comparator.comparingLong(Person::getPersonId)).forEach(person -> System.out.println(person.getName()));

Using Comparator.comparing() method(Generic method which compares based on the getter method provided):

personList.stream().sorted(Comparator.comparing(Person::getPersonId)).forEach(person -> System.out.println(person.getName()));

We can do chaining too using thenComparing() method:

personList.stream().sorted(Comparator.comparing(Person::getPersonId).thenComparing(Person::getAge)).forEach(person -> System.out.println(person.getName())); //Sorting by person id and then by age.

Person class

public class Person {
    private long personId;
    private String name;
    private int age;
    private double salary;

    public long getPersonId() {
        return personId;
    }

    public void setPersonId(long personId) {
        this.personId = personId;
    }

    public Person(long personId, String name, int age, double salary) {
        this.personId = personId;
        this.name = name;
        this.age = age;

        this.salary = salary;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

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

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }
}

If you just made a migration, you can rollback and then make your migration again.

To rollback you can do as many steps as you want:

rake db:rollback STEP=1

Or, if you are using Rails 5.2 or newer:

rails db:rollback STEP=1

Then, you can just make the migration again:

def change
  add_column :profiles, :show_attribute, :boolean, default: true
end

Don't forget to rake db:migrate and if you are using heroku heroku run rake db:migrate

I wrote an article on topis how to [manually install curl on debian linu][1]x.

[1]: http://www.jasom.net/how-to-install-curl-command-manually-on-debian-linux. This is its shortcut:

1. cd /usr/local/src
2. wget http://curl.haxx.se/download/curl-7.36.0.tar.gz
3. tar -xvzf curl-7.36.0.tar.gz
4. rm *.gz
5. cd curl-7.6.0
6. ./configure
7. make
8. make install

And restart Apache. If you will have an error during point 6, try to run apt-get install build-essential.

On Windows, I strongly recommand installing latest Visual Stuido Community, it's free, you will maybe miss some build tools if you only install vc_redist, so you can easily install package by pip instead of wheel, it save lot of time

In my case, clearing caché didn't work.

On SDK Manager, be sure to check the box on "show package descriptions"; then you should also select the "Google APIs" for the version you are willing to install.

Install it and then you should be ok

You don't need to --relocate since the branch is within the same repository URL. Just do:

svn switch https://www.example.com/svn/branches/v1p2p3

You should use the background attribute to give an image to that element, and I would use ::after instead of before, this way it should be already drawn on top of your element.

.Modal:before{
  content: '';
  background:url('blackCarrot.png');
  width: /* width of the image */;
  height: /* height of the image */;
  display: block;
}

The @Transactional annotation takes a timeout parameter where you can specify timeout in seconds for a specific method in the @RestController

@RequestMapping(value = "/method",
    method = RequestMethod.POST,
    produces = MediaType.APPLICATION_JSON_VALUE)
@Timed
@Transactional(timeout = 120)

User Leigh Webber on the social.msdn.microsoft.com site posted VBA code implementing an easy-to-use clipboard interface that uses the Windows API:

http://social.msdn.microsoft.com/Forums/en/worddev/thread/ee9e0d28-0f1e-467f-8d1d-1a86b2db2878

You can get Leigh Webber's source code here

If this link doesn't go through, search for "A clipboard object for VBA" in the Office Dev Center > Microsoft Office for Developers Forums > Word for Developers section.

I created the two classes, ran his test cases, and it worked perfectly inside Outlook 2007 SP3 32-bit VBA under Windows 7 64-bit. It will most likely work for Access. Tip: To rename classes, select the class in the VBA 'Project' window, then click 'View' on the menu bar and click 'Properties Window' (or just hit F4).

With his classes, this is what it takes to copy to/from the clipboard:

Dim myClipboard As New vbaClipboard  ' Create clipboard

' Copy text to clipboard as ClipboardFormat TEXT (CF_TEXT)    
myClipboard.SetClipboardText "Text to put in clipboard", "CF_TEXT"    

' Retrieve clipboard text in CF_TEXT format (CF_TEXT = 1)
mytxt = myClipboard.GetClipboardText(1)

He also provides other functions for manipulating the clipboard.

It also overcomes 32KB MSForms_DataObject.SetText limitation - the main reason why SetText often fails. However, bear in mind that, unfortunatelly, I haven't found a reference on Microsoft recognizing this limitation.

Here's a really simple solution that worked for me,

<span id="text">Extra Text</span>
<span id="more">show more...</span>
<span id="less">show less...</span>

<script>
 $("#text").hide();
 $("#less").hide();
 $("#more").click( function() {
   $("#text").show();
   $("#less").show();
   $("#more").hide();
 });
 $("#less").click( function() {
   $("#text").hide();
   $("#less").hide();
   $("#more").show();
 });
</script>

content doesn't support HTML, only text. You should probably use javascript, jQuery or something like that.

Another problem with your code is " inside a " block. You should mix ' and " (class='headingDetail').

If content did support HTML you could end up in an infinite loop where content is added inside content.

Well I always use the same easy way and it works for me. In your HTML keep the type as text (like this):

<input type="text" class="textfield" value="" id="onlyNumbers" name="onlyNumbers" onkeypress="return isNumber(event)" onpaste="return false;"/>

After this you only need to add a method on javascript

<script type="text/javascript">     
function isNumber(evt) {
        evt = (evt) ? evt : window.event;
        var charCode = (evt.which) ? evt.which : evt.keyCode;
        if ( (charCode > 31 && charCode < 48) || charCode > 57) {
            return false;
        }
        return true;
    }
</script>

With this easy validation you will only get positive numbers as you wanted. You can modify the charCodes to add more valid keys to your method.

Here´s the code working: Only numbers validation

Where it is often the text function you use (e.g. in divs etc) then for text area it is val

get:

$('#myTextBox').val();

set:

$('#myTextBox').val('new value');

find supports wildcard matches, just add a *:

find / -type d -name "ora10*"

You can use the GraphRequest class to issue calls to the Facebook Graph API to get user information. See https://developers.facebook.com/docs/android/graph for more info.

You forgot to declare the variable. Just put var in front of signedIn = false

Do not set the background-color inside the print stylesheet. Just set the attribute in the normal css file and it works fine :)

I want to contribute an answer here as I too have faced the same issue - we want the $_FILES element available as part of the same post as another form. My answer is based on @mrtnmgs however notes the comments added to that question.

Firstly: Dropzone posts its data via ajax

Just because you use the formData.append option still means that you must tackle the UX actions - i.e. this all happens behind the scenes and isn't a typical form post. Data is posted to your url parameter.

Secondly: If you therefore want to mimic a form post you will need to store the posted data

This requires server side code to store your $_POST or $_FILES in a session which is available to the user on another page load as the user will not go to the page where the posted data is received.

Thirdly: You need to redirect the user to the page where this data is actioned

Now you have posted your data, stored it in a session, you need to display/action it for the user in an additional page. You need to send the user to that page as well.

So for my example:

[Dropzone code: Uses Jquery]

$('#dropArea').dropzone({
    url:        base_url+'admin/saveProject',
    maxFiles:   1,
    uploadMultiple: false,
    autoProcessQueue:false,
    addRemoveLinks: true,
    init:       function(){
        dzClosure = this;

        $('#projectActionBtn').on('click',function(e) {
            dzClosure.processQueue(); /* My button isn't a submit */
        });

        // My project only has 1 file hence not sendingmultiple
        dzClosure.on('sending', function(data, xhr, formData) {
            $('#add_user input[type="text"],#add_user textarea').each(function(){
                formData.append($(this).attr('name'),$(this).val());
            })
        });

        dzClosure.on('complete',function(){
            window.location.href = base_url+'admin/saveProject';
        })
    },
});

If you have just added the submodule, and for example, you simply added the wrong submodule or you added it to the wrong place, simply do git stash then delete the folder. This is assuming that adding the submodule is the only thing you did in the recent repo.

There are many ways can do that!

jQuery

1. remove all class
   $("element").removeClass();
   OR
   $("#item").removeAttr('class');
   OR
   $("#item").attr('class', '');
   OR
   $('#item')[0].className = '';

2. remove multi class
   $("element").removeClass("class1 ... classn");
   OR
   $("element").removeClass("class1").removeClass("...").removeClass("classn");

Vanilla Javascript

1. remove all class

// remove all items all class  _x000D_
const items = document.querySelectorAll('item');_x000D_
for (let i = 0; i < items.length; i++) {_x000D_
    items[i].className = '';_x000D_
}

2. remove multi class

// only remove all class of first item_x000D_
const item1 = document.querySelector('item');_x000D_
item1.className = '';

I resolved exact the problem when the service layer is using Visual Studio IIS Express. Just point to 10.0.2.2:port wont work. Instead of messing around the IIS Express as mentioned by other posts, I just put a proxy in front of the IIS Express. For example, apache or nginx. The nginx.conf will look like

 # Mobile API
 server { 
    listen       8090;
    server_name  default_server;

    location / {
        proxy_pass http://localhost:54722;
    }
  }

Then the android needs to points to my IP address as 192.168.x.x:8090

This is an example that works out of the box. If you want less "hacky", you should use inheritance library or such.

Well in a file animal.js you would write:

var method = Animal.prototype;

function Animal(age) {
    this._age = age;
}

method.getAge = function() {
    return this._age;
};

module.exports = Animal;

To use it in other file:

var Animal = require("./animal.js");

var john = new Animal(3);

If you want a "sub class" then inside mouse.js:

var _super = require("./animal.js").prototype,
    method = Mouse.prototype = Object.create( _super );

method.constructor = Mouse;

function Mouse() {
    _super.constructor.apply( this, arguments );
}
//Pointless override to show super calls
//note that for performance (e.g. inlining the below is impossible)
//you should do
//method.$getAge = _super.getAge;
//and then use this.$getAge() instead of super()
method.getAge = function() {
    return _super.getAge.call(this);
};

module.exports = Mouse;

Also you can consider "Method borrowing" instead of vertical inheritance. You don't need to inherit from a "class" to use its method on your class. For instance:

 var method = List.prototype;
 function List() {

 }

 method.add = Array.prototype.push;

 ...

 var a = new List();
 a.add(3);
 console.log(a[0]) //3;

/* (opener) */ (closer)

for example,

<html>
 /*<p>Commented P Tag </p>*/
<html>

Xcode 11+, Swift 5.

According to @WantToKnow answer, I solved my issue, I prepared video and code

As simple as this

x = "some data you want to return"
return x, 200, {'Content-Type': 'text/css; charset=utf-8'}

Hope it helps

Update: Use this method because it will work with both python 2.x and python 3.x

and secondly it also eliminates multiple header problem.

from flask import Response
r = Response(response="TEST OK", status=200, mimetype="application/xml")
r.headers["Content-Type"] = "text/xml; charset=utf-8"
return r

Since strings are lists of characters in Python, we can concatenate strings the same way we concatenate lists (with the + sign):

{{ var1 + '-' + var2 + '-' + var3 }}

If you want to pipe the resulting string to some filter, make sure you enclose the bits in parentheses:

e.g. To concatenate our 3 vars, and get a sha512 hash:

{{ (var1 + var2 + var3) | hash('sha512') }}

Note: this works on Ansible 2.3. I haven't tested it on earlier versions.

The other answers didn't cover the case where you want forked processes to share your new stdout.

To do that:

from os import open, close, dup, O_WRONLY

old = dup(1)
close(1)
open("file", O_WRONLY) # should open on 1

..... do stuff and then restore

close(1)
dup(old) # should dup to 1
close(old) # get rid of left overs

If your data contains any newlines or commas, you will need to escape those first:

const escape = text =>
    text.replace(/\\/g, "\\\\")
        .replace(/\n/g, "\\n")
        .replace(/,/g, "\\,")

escaped_array = test_array.map(fields => fields.map(escape))

Then simply do:

csv = escaped_array.map(fields => fields.join(","))
                .join("\n")

If you want to make it downloadable in-browser:

dl = "data:text/csv;charset=utf-8," + csv
window.open(encodeURI(dl))

[Edit] After reviewing the Mongoose documentation, it looks like you can send each query result as a separate chunk; the web server uses chunked transfer encoding by default so all you have to do is wrap an array around the items to make it a valid JSON object.

Roughly (untested):

app.get('/users/:email/messages/unread', function(req, res, next) {
  var firstItem=true, query=MessageInfo.find(/*...*/);
  res.writeHead(200, {'Content-Type': 'application/json'});
  query.each(function(docs) {
    // Start the JSON array or separate the next element.
    res.write(firstItem ? (firstItem=false,'[') : ',');
    res.write(JSON.stringify({ msgId: msg.fileName }));
  });
  res.end(']'); // End the JSON array and response.
});

Alternatively, as you mention, you can simply send the array contents as-is. In this case the response body will be buffered and sent immediately, which may consume a large amount of additional memory (above what is required to store the results themselves) for large result sets. For example:

// ...
var query = MessageInfo.find(/*...*/);
res.writeHead(200, {'Content-Type': 'application/json'});
res.end(JSON.stringify(query.map(function(x){ return x.fileName })));

as JSON only allows enclosing strings with double quotes you can manipulate the string like this:

str = str.replace("\'", "\"")

if your JSON holds escaped single-quotes (\') then you should use the more precise following code:

import re
p = re.compile('(?<!\\\\)\'')
str = p.sub('\"', str)

This will replace all occurrences of single quote with double quote in the JSON string str and in the latter case will not replace escaped single-quotes.

You can also use js-beautify which is less strict:

$ pip install jsbeautifier
$ js-beautify file.js

import datetime
mydate = datetime.datetime.now()
mydate.strftime("%B") # 'December'
mydate.strftime("%b") # 'dec'

I guess you mean this:

class Value:
    def __init__(self, v=None):
        self.v = v

v1 = Value(1)
v2 = Value(2)

d = {'a': v1, 'b': v1, 'c': v2, 'd': v2}
d['a'].v += 1

d['b'].v == 2 # True

• Python's strings and numbers are immutable objects,
• So, if you want d['a'] and d['b'] to point to the same value that "updates" as it changes, make the value refer to a mutable object (user-defined class like above, or a dict, list, set).
• Then, when you modify the object at d['a'], d['b'] changes at same time because they both point to same object.

I think you can adapt the function to substract the two timestamps:

return  EXTRACT(MINUTE FROM 
  TO_TIMESTAMP(to_char(p_date1,'DD-MON-YYYY HH:MI:SS'),'DD-MON-YYYY HH24:MI:SS')
-
  TO_TIMESTAMP(to_char(p_date2,'DD-MON-YYYY HH:MI:SS'),'DD-MON-YYYY HH24:MI:SS')
);

I think you could simplify it by just using CAST(p_date as TIMESTAMP).

return  EXTRACT(MINUTE FROM cast(p_date1 as TIMESTAMP) - cast(p_date2 as TIMESTAMP));

Remember dates and timestamps are big ugly numbers inside Oracle, not what we see in the screen; we don't need to tell him how to read them. Also remember timestamps can have a timezone defined; not in this case.

MDN has the following to say about string.concat():

It is strongly recommended to use the string concatenation operators (+, +=) instead of this method for perfomance reasons

Also see the link by @Bergi.

The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.

According to this Google blogpost:

It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.

When referencing the mipmap- folders ensure you are using the following reference:

android:icon="@mipmap/ic_launcher"

The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.

You need to use the bracket notation because key is a variable holding the key as a value

$.each(sjonObj, function(key,value){
   // console.log(value);
    if(value==""||value==null){
        delete sjonObj[key];
    }

});

delete sjonObj.key deletes the property called key from sjonObj, instead you need to use key as a variable holding the property name.

Note: Still it will not handle the nested objects

Any of this solution works for me

This the solution i have for Swift 4 :

let monday = Day(name: "M")
let tuesday = Day(name: "T")
let friday = Day(name: "F")

let days = [monday, tuesday, friday]

let index = days.index(where: { 
            //important to test with === to be sure it's the same object reference
            $0 === tuesday
        })

If you control the input data, you can use the mini version

package main

import (
    "testing"
    "strconv"
)

func Atoi (s string) int {
    var (
        n uint64
        i int
        v byte
    )   
    for ; i < len(s); i++ {
        d := s[i]
        if '0' <= d && d <= '9' {
            v = d - '0'
        } else if 'a' <= d && d <= 'z' {
            v = d - 'a' + 10
        } else if 'A' <= d && d <= 'Z' {
            v = d - 'A' + 10
        } else {
            n = 0; break        
        }
        n *= uint64(10) 
        n += uint64(v)
    }
    return int(n)
}

func BenchmarkAtoi(b *testing.B) {
    for i := 0; i < b.N; i++ {
        in := Atoi("9999")
        _ = in
    }   
}

func BenchmarkStrconvAtoi(b *testing.B) {
    for i := 0; i < b.N; i++ {
        in, _ := strconv.Atoi("9999")
        _ = in
    }   
}

the fastest option (write your check if necessary). Result :

The problem is that Properties implements Map<Object, Object>, whereas the HashMap constructor expects a Map<? extends String, ? extends String>.

This answer explains this (quite counter-intuitive) decision. In short: before Java 5, Properties implemented Map (as there were no generics back then). This meant that you could put any Object in a Properties object. This is still in the documenation:

Because Properties inherits from Hashtable, the put and putAll methods can be applied to a Properties object. Their use is strongly discouraged as they allow the caller to insert entries whose keys or values are not Strings. The setProperty method should be used instead.

To maintain compatibility with this, the designers had no other choice but to make it inherit Map<Object, Object> in Java 5. It's an unfortunate result of the strive for full backwards compatibility which makes new code unnecessarily convoluted.

If you only ever use string properties in your Properties object, you should be able to get away with an unchecked cast in your constructor:

Map<String, String> map = new HashMap<String, String>( (Map<String, String>) properties);

or without any copies:

Map<String, String> map = (Map<String, String>) properties;

Wrap all the children inside of another LinearLayout with wrap_content for both the width and the height as well as the vertical orientation.

yes no more function extending for setup setter & getter this is my example Object.defineProperty(obj,name,func)

var obj = {};
['data', 'name'].forEach(function(name) {
    Object.defineProperty(obj, name, {
        get : function() {
            return 'setter & getter';
        }
    });
});


console.log(obj.data);
console.log(obj.name);

Alongside nmaier's answer, as he said you'll always receive code 1006. However, if you were to somehow theoretically receive other codes, here is code to display the results (via RFC6455).

you will almost never get these codes in practice so this code is pretty much pointless

There are two main ways that you can do this. One of them is the standard CakePHP way, and the other is using a custom join.

It's worth pointing out that this advice is for CakePHP 2.x, not 3.x.

The CakePHP Way

You would create a relationship with your User model and Messages Model, and use the containable behavior:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array('Message');
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array('User');
}

You need to change the messages.from column to be messages.user_id so that cake can automagically associate the records for you.

Then you can do this from the messages controller:

$this->Message->find('all', array(
    'contain' => array('User')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

The (other) CakePHP way

I recommend using the first method, because it will save you a lot of time and work. The first method also does the groundwork of setting up a relationship which can be used for any number of other find calls and conditions besides the one you need now. However, cakePHP does support a syntax for defining your own joins. It would be done like this, from the MessagesController:

$this->Message->find('all', array(
    'joins' => array(
        array(
            'table' => 'users',
            'alias' => 'UserJoin',
            'type' => 'INNER',
            'conditions' => array(
                'UserJoin.id = Message.from'
            )
        )
    ),
    'conditions' => array(
        'Message.to' => 4
    ),
    'fields' => array('UserJoin.*', 'Message.*'),
    'order' => 'Message.datetime DESC'
));

Note, I've left the field name messages.from the same as your current table in this example.

Using two relationships to the same model

Here is how you can do the first example using two relationships to the same model:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array(
        'MessagesSent' => array(
            'className'  => 'Message',
            'foreignKey' => 'from'
         )
    );
    public $belongsTo = array(
        'MessagesReceived' => array(
            'className'  => 'Message',
            'foreignKey' => 'to'
         )
    );
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array(
        'UserFrom' => array(
            'className'  => 'User',
            'foreignKey' => 'from'
        )
    );
    public $hasMany = array(
        'UserTo' => array(
            'className'  => 'User',
            'foreignKey' => 'to'
        )
    );
}

Now you can do your find call like this:

$this->Message->find('all', array(
    'contain' => array('UserFrom')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

If you want to implement a public class, you must implement it in a file with the same name as that class. A single file can contain one public and optionally some private classes. This is useful if the classes are only used internally by the public class. Additionally the public class can also contain inner classes.

Although it is fine to have one or more private classes in a single source file, I would say that is more readable to use inner and anonymous classes instead. For example one can use an anonymous class to define a Comparator class inside a public class:

  public static Comparator MyComparator = new Comparator() {
    public int compare(Object obj, Object anotherObj) {

    }
  };

The Comparator class will normally require a separate file in order to be public. This way it is bundled with the class that uses it.

Have you tried using the wmic commands?

Try wmic os get version

This will give you the version number in a command line, then you just need to integrate into the batch file.

Try this to read a file:

BufferedReader reader = null;

try {
    File file = new File("sample-file.dat");
    reader = new BufferedReader(new FileReader(file));

    String line;
    while ((line = reader.readLine()) != null) {
        System.out.println(line);
    }

} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        reader.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

const lastElement = myArray[myArray.length - 1];

This is the best options from performance point of view (~1000 times faster than arr.slice(-1)).

If you want to pass data to form2 from form1 without passing like new form(sting "data");

Do like that in form 1

using (Form2 form2= new Form2())
{
   form2.ReturnValue1 = "lalala";
   form2.ShowDialog();
}

in form 2 add

public string ReturnValue1 { get; set; }

private void form2_Load(object sender, EventArgs e)
{
   MessageBox.Show(ReturnValue1);
}

Also you can use value in form1 like this if you want to swap something in form1

just in form1

textbox.Text =form2.ReturnValue1

I think you want to make objects from array and combine it with an old object (BODY.recipients.values), if it's then you may do it using $.extent (because you are using jQuery/tagged) method after prepare the object from array

var BODY = {
    "recipients": {
        "values": []
    },
    "subject": 'TitleOfSubject',
    "body": 'This is the message body.'
}

var values = [],
names = ['sheikh', 'muhammed', 'Answer', 'Uddin', 'Heera']; // for testing
for (var ln = 0; ln < names.length; ln++) {
    var item1 = {
        "person": { "_path": "/people/"+names[ln] }
    };
    values.push(item1);
}

// Now merge with BODY
$.extend(BODY.recipients.values, values);

DEMO.

Combination of lambda and map function can also do the job:

list_ = ['a', 'b', 'b', 'c']
sum(map(lambda x: x=="b", list_))
:2

You can also use Requestify, a really cool and very simple HTTP client I wrote for nodeJS + it supports caching.

Just do the following for executing a POST request:

var requestify = require('requestify');

requestify.post('http://example.com', {
    hello: 'world'
})
.then(function(response) {
    // Get the response body (JSON parsed or jQuery object for XMLs)
    response.getBody();
});

Try this:

<td bgcolor="#FFFFFF" style="line-height:10px;" colspan=3>&nbsp;</td>

This one automatically excludes the trailing comma, unlike most of the other answers.

DECLARE @csv VARCHAR(1000)

SELECT @csv = COALESCE(@csv + ',', '') + ModuleValue
FROM Table_X
WHERE ModuleID = @ModuleID

(If the ModuleValue column isn't already a string type then you might need to cast it to a VARCHAR.)

Bless is a high quality, full featured hex editor.

It is written in mono/Gtk# and its primary platform is GNU/Linux. However it should be able to run without problems on every platform that mono and Gtk# run.

Bless currently provides the following features:

• Efficient editing of large data files and block devices.
• Multilevel undo - redo operations.
• Customizable data views.
• Fast data rendering on screen.
• Multiple tabs.
• Fast find and replace operations.
• A data conversion table.
• Advanced copy/paste capabilities.
• Highlighting of selection pattern matches in the file.
• Plugin based architecture.
• Export of data to text and html (others with plugins).
• Bitwise operations on data.
• A comprehensive user manual.

wxHexEditor is another Free Hex Editor, built because there is no good hex editor for Linux system, specially for big files.

• It uses 64 bit file descriptors (supports files or devices up to 2^64 bytes , means some exabytes but tested only 1 PetaByte file (yet). ).
• It does NOT copy whole file to your RAM. That make it FAST and can open files (which sizes are Multi Giga < Tera < Peta < Exabytes)
• Could open your devices on Linux, Windows or MacOSX.
• Memory Usage : Currently ~10 MegaBytes while opened multiple > ~8GB files.
• Could operate thru XOR encryption.
• Written with C++/wxWidgets GUI libs and can be used with other OSes such as Mac OS, Windows as native application.
• You can copy/edit your Disks, HDD Sectors with it.( Usefull for rescue files/partitions by hand. )
• You can delete/insert bytes to file, more than once, without creating temp file.

DHEX is a more than just another hex editor: It includes a diff mode, which can be used to easily and conveniently compare two binary files. Since it is based on ncurses and is themeable, it can run on any number of systems and scenarios. With its utilization of search logs, it is possible to track changes in different iterations of files easily. Wikipedia article
