if path.exists(Score_file):
      try : 
         with open(Score_file , "rb") as prev_Scr:

            return Unpickler(prev_Scr).load()

    except EOFError : 

        return dict() 

convert your inputs to ints:

width = int(input())
height = int(input())

.communicate() writes input (there is no input in this case so it just closes subprocess' stdin to indicate to the subprocess that there is no more input), reads all output, and waits for the subprocess to exit.

The exception EOFError is raised in the child process by raw_input() (it expected data but got EOF (no data)).

p.stdout.read() hangs forever because it tries to read all output from the child at the same time as the child waits for input (raw_input()) that causes a deadlock.

To avoid the deadlock you need to read/write asynchronously (e.g., by using threads or select) or to know exactly when and how much to read/write, for example:

from subprocess import PIPE, Popen

p = Popen(["python", "-u", "1st.py"], stdin=PIPE, stdout=PIPE, bufsize=1)
print p.stdout.readline(), # read the first line
for i in range(10): # repeat several times to show that it works
    print >>p.stdin, i # write input
    p.stdin.flush() # not necessary in this case
    print p.stdout.readline(), # read output

print p.communicate("n\n")[0], # signal the child to exit,
                               # read the rest of the output, 
                               # wait for the child to exit

Note: it is a very fragile code if read/write are not in sync; it deadlocks.

Beware of block-buffering issue (here it is solved by using "-u" flag that turns off buffering for stdin, stdout in the child).

bufsize=1 makes the pipes line-buffered on the parent side.

r+ is used for reading, and writing mode. b is for binary. r+b mode is open the binary file in read or write mode.
You can read more here.

help(input) shows what keyboard shortcuts produce EOF, namely, Unix: Ctrl-D, Windows: Ctrl-Z+Return:

input([prompt]) -> string

Read a string from standard input. The trailing newline is stripped. If the user hits EOF (Unix: Ctl-D, Windows: Ctl-Z+Return), raise EOFError. On Unix, GNU readline is used if enabled. The prompt string, if given, is printed without a trailing newline before reading.

You could reproduce it using an empty file:

$ touch empty
$ python3 -c "input()" < empty
Traceback (most recent call last):
  File "<string>", line 1, in <module>
EOFError: EOF when reading a line

You could use /dev/null or nul (Windows) as an empty file for reading. os.devnull shows the name that is used by your OS:

$ python3 -c "import os; print(os.devnull)"
/dev/null

Note: input() happily accepts input from a file/pipe. You don't need stdin to be connected to the terminal:

$ echo abc | python3 -c "print(input()[::-1])"
cba

Either handle EOFError in your code:

try:
    reply = input('Enter text')
except EOFError:
    break

Or configure your editor to provide a non-empty input when it runs your script e.g., by using a customized command line if it allows it: python3 "%f" < input_file

In Ruby on Rails I used this code, and it works perfectly:

req_profilepic = ActiveSupport::JSON.decode(open(URI.encode("https://graph.facebook.com/me/?fields=picture&type=large&access_token=#{fb_access_token}")))

profilepic_url = req_profilepic['picture']

You didn't open the file in binary mode.

open("Fruits.obj",'rb')

Should work.

For your second error, the file is most likely empty, which mean you inadvertently emptied it or used the wrong filename or something.

(This is assuming you really did close your session. If not, then it's because you didn't close the file between the write and the read).

I tested your code, and it works.

Sounds like you have a utility class similar to java.lang.Math.
The approach there is final class with private constructor and static methods.

But beware of what this does for testability, I recommend reading this article
Static Methods are Death to Testability

What about C's standard atoi?

int num = atoi([scannedNumber cStringUsingEncoding:NSUTF8StringEncoding]);

Do you think there are any caveats?

It's overly-complicated and ugly but in my opinion this is the way to go:

$fp = fopen("php://memory", 'r+');
fputs($fp, $data);
rewind($fp);
while($line = fgets($fp)){
  // deal with $line
}
fclose($fp);

In case anyone would be searching - I created utility for automated import of xlsx files into google spreadsheet: xls2sheets. One can do it automatically via setting up the cronjob for ./cmd/sheets-refresh, readme describes it all. Hope that would be of use.

when you invoke a function , it is termed 'calling' a function . For eg , suppose you've defined a function that finds the average of two numbers like this-

def avgg(a,b) :
        return (a+b)/2;

now, to call the function , you do like this .

x=avgg(4,6)
print x

value of x will be 5 .

This is the classroom problem called 'Longest sequence finder'. I have given some simple code that worked for me, also my inputs are lists of a sequence which can also be a string:

def longest_substring(list1,list2):
    both=[]
    if len(list1)>len(list2):
        small=list2
        big=list1
    else:
        small=list1
        big=list2
    removes=0
    stop=0
    for i in small:
        for j in big:
            if i!=j:
                removes+=1
                if stop==1:
                    break
            elif i==j:
                both.append(i)
                for q in range(removes+1):
                    big.pop(0)
                stop=1
                break
        removes=0
    return both

If you own the HTML code then it might be wise to assign an id to this href. Then your code would look like this:

<a id="sign_up" class="sign_new">Sign up</a>

And jQuery:

$(document).ready(function(){
    $('#sign_up').click(function(){
        alert('Sign new href executed.');
    });
});

If you do not own the HTML then you'd need to change $('#sign_up') to $('a.sign_new'). You might also fire event.stopPropagation() if you have a href in anchor and do not want it handled (AFAIR return false might work as well).

$(document).ready(function(){
    $('#sign_up').click(function(event){
        alert('Sign new href executed.');
        event.stopPropagation();
    });
});

There's a free trial for 100 minutes on https://browserling.com and you can test on Safari v7.0 during the trial period.

jQuery is not the same as an array. If you want to append something at the end of a jQuery object, use:

$('#fruit').append(veggies);

or to append it to the end of a form value like in your example:

 $('#fruit').val($('#fruit').val()+veggies);

In your case, fruitvegbasket is a string that contains the current value of #fruit, not an array.

jQuery (jquery.com) allows for DOM manipulation, and the specific function you called val() returns the value attribute of an input element as a string. You can't push something onto a string.

Different Means of Exiting

os._exit():

• Exit the process without calling the cleanup handlers.

exit(0):

• a clean exit without any errors / problems.

exit(1):

• There was some issue / error / problem and that is why the program is exiting.

sys.exit():

• When the system and python shuts down; it means less memory is being used after the program is run.

quit():

• Closes the python file.

Summary

Basically they all do the same thing, however, it also depends on what you are doing it for.

I don't think you left anything out and I would recommend getting used to quit() or exit().

You would use sys.exit() and os._exit() mainly if you are using big files or are using python to control terminal.

Otherwise mainly use exit() or quit().

import os

os.system("awk '(NR == 1) || (FNR > 1)' file*.csv > merged.csv")

Where NR and FNR represent the number of the line being processed.

FNR is the current line within each file.

NR == 1 includes the first line of the first file (the header), while (FNR > 1) skips the first line of each subsequent file.

Use this below code

 border:2px soild #eee;

 margin: 15px 15px;
 -webkit-box-shadow: 2px 3px 8px #eee;
-moz-box-shadow: 2px 3px 8px #eee;
box-shadow: 2px 3px 8px #eee;

Explanation:-

box-shadow requires you to set the horizontal & vertical offsets, you can then optionally set the blur and colour, you can also choose to have the shadow inset instead of the default outset. Colour can be defined as hex or rgba.

box-shadow : inset/outset h-offset v-offset blur spread color;

Explanation of the values...

inset/outset -- whether the shadow is inside or outside the box. If not specified it will default to outset.

h-offset -- the horizontal offset of the shadow (required value)

v-offset -- the vertical offset of the shadow (required value)

blur -- as it says, the blur of the shadow

spread -- moves the shadow away from the box equally on all sides. A positive value causes the shadow to expand, negative causes it to contract. Though this value isn't often used, it is useful with multiple shadows.

color -- as it says, the color of the shadow

Usage

box-shadow:2px 3px 8px #eee; a gray shadow with a horizontal outset of 2px, vertical of 3px and a blur of 8px

How about writing your own concat method?

public static Stream<T> concat(Stream<? extends T> a, 
                               Stream<? extends T> b, 
                               Stream<? extends T> args)
{
    Stream<T> concatenated = Stream.concat(a, b);
    for (Stream<T> stream : args)
    {
        concatenated = Stream.concat(concatenated, stream);
    }
    return concatenated;
}

This at least makes your first example a lot more readable.

What does the “at” (@) symbol do in Python?

In short, it is used in decorator syntax and for matrix multiplication.

In the context of decorators, this syntax:

@decorator
def decorated_function():
    """this function is decorated"""

is equivalent to this:

def decorated_function():
    """this function is decorated"""

decorated_function = decorator(decorated_function)

In the context of matrix multiplication, a @ b invokes a.__matmul__(b) - making this syntax:

a @ b

equivalent to

dot(a, b)

and

a @= b

equivalent to

a = dot(a, b)

where dot is, for example, the numpy matrix multiplication function and a and b are matrices.

How could you discover this on your own?

I also do not know what to search for as searching Python docs or Google does not return relevant results when the @ symbol is included.

If you want to have a rather complete view of what a particular piece of python syntax does, look directly at the grammar file. For the Python 3 branch:

~$ grep -C 1 "@" cpython/Grammar/Grammar 

decorator: '@' dotted_name [ '(' [arglist] ')' ] NEWLINE
decorators: decorator+
--
testlist_star_expr: (test|star_expr) (',' (test|star_expr))* [',']
augassign: ('+=' | '-=' | '*=' | '@=' | '/=' | '%=' | '&=' | '|=' | '^=' |
            '<<=' | '>>=' | '**=' | '//=')
--
arith_expr: term (('+'|'-') term)*
term: factor (('*'|'@'|'/'|'%'|'//') factor)*
factor: ('+'|'-'|'~') factor | power

We can see here that @ is used in three contexts:

• decorators
• an operator between factors
• an augmented assignment operator

Decorator Syntax:

A google search for "decorator python docs" gives as one of the top results, the "Compound Statements" section of the "Python Language Reference." Scrolling down to the section on function definitions, which we can find by searching for the word, "decorator", we see that... there's a lot to read. But the word, "decorator" is a link to the glossary, which tells us:

decorator

A function returning another function, usually applied as a function transformation using the @wrapper syntax. Common examples for decorators are classmethod() and staticmethod().

The decorator syntax is merely syntactic sugar, the following two function definitions are semantically equivalent:

def f(...):
    ...
f = staticmethod(f)

@staticmethod
def f(...):
    ...

The same concept exists for classes, but is less commonly used there. See the documentation for function definitions and class definitions for more about decorators.

So, we see that

@foo
def bar():
    pass

is semantically the same as:

def bar():
    pass

bar = foo(bar)

They are not exactly the same because Python evaluates the foo expression (which could be a dotted lookup and a function call) before bar with the decorator (@) syntax, but evaluates the foo expression after bar in the other case.

_{(If this difference makes a difference in the meaning of your code, you should reconsider what you're doing with your life, because that would be pathological.)}

Stacked Decorators

If we go back to the function definition syntax documentation, we see:

@f1(arg)
@f2
def func(): pass

is roughly equivalent to

def func(): pass
func = f1(arg)(f2(func))

This is a demonstration that we can call a function that's a decorator first, as well as stack decorators. Functions, in Python, are first class objects - which means you can pass a function as an argument to another function, and return functions. Decorators do both of these things.

If we stack decorators, the function, as defined, gets passed first to the decorator immediately above it, then the next, and so on.

That about sums up the usage for @ in the context of decorators.

The Operator, @

In the lexical analysis section of the language reference, we have a section on operators, which includes @, which makes it also an operator:

The following tokens are operators:

+       -       *       **      /       //      %      @
<<      >>      &       |       ^       ~
<       >       <=      >=      ==      !=

and in the next page, the Data Model, we have the section Emulating Numeric Types,

object.__add__(self, other)
object.__sub__(self, other) 
object.__mul__(self, other) 
object.__matmul__(self, other) 
object.__truediv__(self, other) 
object.__floordiv__(self, other)

[...] These methods are called to implement the binary arithmetic operations (+, -, *, @, /, //, [...]

And we see that __matmul__ corresponds to @. If we search the documentation for "matmul" we get a link to What's new in Python 3.5 with "matmul" under a heading "PEP 465 - A dedicated infix operator for matrix multiplication".

it can be implemented by defining __matmul__(), __rmatmul__(), and __imatmul__() for regular, reflected, and in-place matrix multiplication.

(So now we learn that @= is the in-place version). It further explains:

Matrix multiplication is a notably common operation in many fields of mathematics, science, engineering, and the addition of @ allows writing cleaner code:

S = (H @ beta - r).T @ inv(H @ V @ H.T) @ (H @ beta - r)

instead of:

S = dot((dot(H, beta) - r).T,
        dot(inv(dot(dot(H, V), H.T)), dot(H, beta) - r))

While this operator can be overloaded to do almost anything, in numpy, for example, we would use this syntax to calculate the inner and outer product of arrays and matrices:

>>> from numpy import array, matrix
>>> array([[1,2,3]]).T @ array([[1,2,3]])
array([[1, 2, 3],
       [2, 4, 6],
       [3, 6, 9]])
>>> array([[1,2,3]]) @ array([[1,2,3]]).T
array([[14]])
>>> matrix([1,2,3]).T @ matrix([1,2,3])
matrix([[1, 2, 3],
        [2, 4, 6],
        [3, 6, 9]])
>>> matrix([1,2,3]) @ matrix([1,2,3]).T
matrix([[14]])

Inplace matrix multiplication: @=

While researching the prior usage, we learn that there is also the inplace matrix multiplication. If we attempt to use it, we may find it is not yet implemented for numpy:

>>> m = matrix([1,2,3])
>>> m @= m.T
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: In-place matrix multiplication is not (yet) supported. Use 'a = a @ b' instead of 'a @= b'.

When it is implemented, I would expect the result to look like this:

>>> m = matrix([1,2,3])
>>> m @= m.T
>>> m
matrix([[14]])

1.9.3p194 :001 > ["", "A", "B", "C", ""].reject(&:empty?)

=> ["A", "B", "C"]

Quoting API on referencedColumnName:

The name of the column referenced by this foreign key column.

Default (only applies if single join column is being used): The same name as the primary key column of the referenced table.

Q/A

Where this would be used?

When there is a composite PK in referenced table, then you need to specify column name you are referencing.

If you want to see the full paths, I would recommend to cd to the top directory (of your drive if using windows)

cd C:\
grep -r somethingtosearch C:\Users\Ozzesh\temp

Or on Linux:

cd /
grep -r somethingtosearch ~/temp

if you really resist on your file name filtering (*.log) AND you want recursive (files are not all in the same directory), combining find and grep is the most flexible way:

cd /
find ~/temp -iname '*.log' -type f -exec grep somethingtosearch '{}' \;

std::pair already has the required comparison operators, which perform lexicographical comparisons using both elements of each pair. To use this, you just have to provide the comparison operators for types for types K and V.

Also bear in mind that std::sort requires a strict weak ordeing comparison, and <= does not satisfy that. You would need, for example, a less-than comparison < for K and V. With that in place, all you need is

std::vector<pair<K,V>> items; 
std::sort(items.begin(), items.end()); 

If you really need to provide your own comparison function, then you need something along the lines of

template <typename K, typename V>
bool comparePairs(const std::pair<K,V>& lhs, const std::pair<K,V>& rhs)
{
  return lhs.first < rhs.first;
}

Before applying

I wanted to make a version of this that uses $.getJSON() from a separate JSON file.

Demo: here

JavaScript:

$(document).ready(function () {
    "use strict";

    var selectData, $states;

    function updateSelects() {
        var cities = $.map(selectData[this.value], function (city) {
            return $("<option />").text(city);
        });
        $("#city_names").empty().append(cities);
    }

    $.getJSON("updateSelect.json", function (data) {
        var state;
        selectData = data;
        $states = $("#us_states").on("change", updateSelects);
        for (state in selectData) {
            $("<option />").text(state).appendTo($states);
        }
        $states.change();
    });
});

bash can redirect to and from TCP/IP sockets. /dev/tcp/ and /dev/udp.

Some people think it's a security issue, but that's what OS level security like Solaris X's jail is for.

As Will Robertson notes, change prompt to do stuff... print the command # for !nn Set the Xterm terminal name. If it's an old Xterm that doesn't sniff traffic to set it's title.

I solved it by editing styles.xml:

<style name="ToolbarColoredBackArrow" parent="AppTheme">
    <item name="android:textColorSecondary">INSERT_COLOR_HERE</item>
</style>

...then referencing the style in the Toolbar definition in the activity:

<LinearLayout
    android:id="@+id/main_parent_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.Toolbar
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"

        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        android:background="?attr/colorPrimary"/>

Sorry if this answer comes so late, but maybe it can be useful for someone else. Actually there is a very useful solution to this problem, explained at the end of ?split.

Thanks Philip this helped me - my use case was I had a form with lot of input fields so I maintained initial state as object and I was not able to update the object state.The above post helped me :)

const [projectGroupDetails, setProjectGroupDetails] = useState({
    "projectGroupId": "",
    "projectGroup": "DDD",
    "project-id": "",
    "appd-ui": "",
    "appd-node": ""    
});

const inputGroupChangeHandler = (event) => {
    setProjectGroupDetails((prevState) => ({
       ...prevState,
       [event.target.id]: event.target.value
    }));
}

<Input 
    id="projectGroupId" 
    labelText="Project Group Id" 
    value={projectGroupDetails.projectGroupId} 
    onChange={inputGroupChangeHandler} 
/>

Your program does not know what precision for decimal numbers to use so it throws:

java.lang.ArithmeticException: Non-terminating decimal expansion

Solution to bypass exception:

MathContext precision = new MathContext(int setPrecisionYouWant); // example 2
BigDecimal a = new BigDecimal("1.6",precision);
BigDecimal b = new BigDecimal("9.2",precision);
a.divide(b) // result = 0.17

I Just enhanced Ege Özcan's dynamic sort to dive deep inside objects. If Data looks like this:

obj = [
    {
        a: { a: 1, b: 2, c: 3 },
        b: { a: 4, b: 5, c: 6 }
    },
    { 
        a: { a: 3, b: 2, c: 1 },
        b: { a: 6, b: 5, c: 4 }
}];

and if you want to sort it over a.a property I think my enhancement helps very well. I add new functionality to objects like this:

Object.defineProperty(Object.prototype, 'deepVal', {
    enumerable: false,
    writable: true,
    value: function (propertyChain) {
        var levels = propertyChain.split('.');
        parent = this;
        for (var i = 0; i < levels.length; i++) {
            if (!parent[levels[i]])
                return undefined;
            parent = parent[levels[i]];
        }
        return parent;
    }
});

and changed _dynamicSort's return function:

return function (a,b) {
        var result = ((a.deepVal(property) > b.deepVal(property)) - (a.deepVal(property) < b.deepVal(property)));
        return result * sortOrder;
    }

And now you can sort by a.a. this way:

obj.sortBy('a.a');

See Commplete script in JSFiddle

You should use this code

this.setVisible(false); //this will close frame i.e. NewJFrame

new NewJFrame().setVisible(true); // Now this will open NewJFrame for you again and will also get refreshed 

You can use curl to update php version.

curl -s http://php-osx.liip.ch/install.sh | bash -s 7.3

Last Step:

export PATH=/usr/local/php5/bin:$PATH

Check the upgraded version

php -v

You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:

Dim MyVar as string = "some text ""hello"" "

This will give the MyVar variable a value of some text "hello".

This is the correct way:

You should declare the length of the array after "="

Veicle[] cars = new Veicle[N];

I solved this by restarting my computer. I'm guessing that this port was being occupied by a process that needed to be killed.

Just use this constructor of List<T>. It accepts any IEnumerable<T> as an argument.

string[] arr = ...
List<string> list = new List<string>(arr);

I'm afraid your posted example is not working, since X and Y aren't defined. So instead of pcolormesh let's use imshow:

import numpy as np
import matplotlib.pyplot as plt

H = np.array([[1, 2, 3, 4],

              [9, 10, 11, 12],

It might be clear for most, but have in mind that a function called inside the function component's body, acts as a beforeRender. This doesn't answer the question of running code on ComponentWillMount (before the first render) but since it is related and might help others I'm leaving it here.

const MyComponent = () => {
  const [counter, setCounter] = useState(0)
  
  useEffect(() => {
    console.log('after render')
  })

  const iterate = () => {
    setCounter(prevCounter => prevCounter+1)
  }

  const beforeRender = () => {
    console.log('before render')
  }

  beforeRender()

  return (
    <div>
      <div>{counter}</div>
      <button onClick={iterate}>Re-render</button>
    </div>
  )
}

export default MyComponent

I had the same problem. Solved it by using a javascript library called FileSaver

Just call

saveAs(file, 'filename');

Full http post request:

$http.post('apiUrl', myObject, { responseType: 'arraybuffer' })
  .success(function(data) {
            var file = new Blob([data], { type: 'application/pdf' });
            saveAs(file, 'filename.pdf');
        });

You can use use findFragmentById in FragmentManager.

Since you are using the Support library (you are extending FragmentActivity) you can use:

getSupportFragmentManager().findFragmentById(R.id.pageview)

If you are not using the support library (so you are on Honeycomb+ and you don't want to use the support library):

getFragmentManager().findFragmentById(R.id.pageview)

Please consider that using the support library is recommended even on Honeycomb+.

if 'a' is already a decimal; adding '.' would make 3.4/b(for example) into 3.4./b

Try float(a)/b

As simply as:

if (numbers.isEmpty()) {...}

Note that a quick look at the documentation would have given you that information.

For ng9 upgraders:

npm i -g core-js@^3

..then:

npm cache clean -f

..followed by:

npm i

Alternative solution can be to remove the rows with blanks in one variable:

df <- subset(df, VAR != "")

we can write the UTF-8 encoded file with java using use PrintWriter to write UTF-8 encoded xml

Or Click here

PrintWriter out1 = new PrintWriter(new File("C:\\abc.xml"), "UTF-8");

This one, from kristopherjohnson is heaps better:

1. It doesn't require an XML document header either.
2. Has clearer exceptions
3. Adds extra behaviour options: OmitXmlDeclaration = true, NewLineOnAttributes = true

4. Less lines of code

   static string PrettyXml(string xml)
   {
       var stringBuilder = new StringBuilder();
   
       var element = XElement.Parse(xml);
   
       var settings = new XmlWriterSettings();
       settings.OmitXmlDeclaration = true;
       settings.Indent = true;
       settings.NewLineOnAttributes = true;
   
       using (var xmlWriter = XmlWriter.Create(stringBuilder, settings))
       {
           element.Save(xmlWriter);
       }
   
       return stringBuilder.ToString();
   }
   

The only thing that needs to be done is add width to the <td> or the <div> inside the <td> depending on the layout you want to achieve.

eg:

<table style="width: 100%;" border="1"><tr>
<td><div style="word-wrap: break-word; width: 100px;">looooooooooodasdsdaasdasdasddddddddddddddddddddddddddddddasdasdasdsadng word</div></td>
<td><span style="display: inline;">Foo</span></td>
</tr></table>

or

 <table style="width: 100%;" border="1"><tr>
    <td width="100" ><div style="word-wrap: break-word; ">looooooooooodasdsdaasdasdasddddddddddddddddddddddddddddddasdasdasdsadng word</div></td>
    <td><span style="display: inline;">Foo</span></td>

</tr></table>

Make sure you have selected your mysql storage engine as Innodb and not MYISAM as Innodb storage engine supports foreign keys in Mysql.

Steps to create foreign keys in phpmyadmin:

1. Tap on structure for the table which will have the foreign key.
2. Create INDEX for the column you want to use as foreign key.
3. Tap on Relation view, placed below the table structure

4. In the Relation view page, you can see select options in front of the field (which was made an INDEX).

UPDATE CASCADE specifies that the column will be updated when the referenced column is updated,

DELETE CASCADE specified rows will be deleted when the referenced rows are deleted.

Alternatively, you can also trigger sql query for the same

ALTER TABLE table_name
ADD CONSTRAINT fk_foreign_key_name
FOREIGN KEY (foreign_key_name)
REFERENCES target_table(target_key_name);

This may not be the best way but it definitely makes sure that exception is not thrown from the code block that is being tested.

import org.assertj.core.api.Assertions;
import org.junit.Test;

public class AssertionExample {

    @Test
    public void testNoException(){
        assertNoException();
    }    

    private void assertException(){
        Assertions.assertThatThrownBy(this::doNotThrowException).isInstanceOf(Exception.class);
    }

    private void assertNoException(){
        Assertions.assertThatThrownBy(() -> assertException()).isInstanceOf(AssertionError.class);
    }

    private void doNotThrowException(){
        //This method will never throw exception
    }
}

You are getting close!

# Find all of the text between paragraph tags and strip out the html
page = soup.find('p').getText()

Using find (as you've noticed) stops after finding one result. You need find_all if you want all the paragraphs. If the pages are formatted consistently ( just looked over one), you could also use something like

soup.find('div',{'id':'ctl00_PlaceHolderMain_RichHtmlField1__ControlWrapper_RichHtmlField'})

to zero in on the body of the article.

I think that moving last operator to the beginning of the next line is a good practice. That way you know right away the purpose of the second line, even it doesn't start with an operator. I also recommend 2 indentation spaces (2 tabs) for a previously broken tab, to differ it from the normal indentation. That is immediately visible as continuing previous line. Therefore I suggest this:

private static final Map<Class<? extends Persistent>, PersistentHelper> class2helper 
            = new HashMap<Class<? extends Persistent>, PersistentHelper>();

Another way to fix this would be to go to the properties of the server on eclipse (right click on server -> properties) In general tab you would see location as workspace.metadata. Click on switch location.

It's a good practice if you need them. It's also a good practice is they make sense, so future coders can understand what you're doing.

But generally, no it's not a good practice to attach 10 class names to an object because most likely whatever you're using them for, you could accomplish the same thing with far fewer classes. Probably just 1 or 2.

To qualify that statement, javascript plugins and scripts may append far more classnames to do whatever it is they're going to do. Modernizr for example appends anywhere from 5 - 25 classes to your body tag, and there's a very good reason for it. jQuery UI appends lots of classnames when you use one of the widgets in that library.

You could loop through the array, printing out each item, as you loop. For example:

String[] items = {"item 1", "item 2", "item 3"};

for(int i = 0; i < items.length; i++) {

    System.out.println(items[i]);

}

Output:

item 1
item 2

This Dynamically changes the background just IOS does

}

This mostly addresses the second line: best practices, assignments, function parameters etc.

General practice. Try to make everything const that you can. Or to put that another way, make everything const to begin with, and then remove exactly the minimum set of consts necessary to allow the program to function. This will be a big help in attaining const-correctness, and will help ensure that subtle bugs don't get introduced when people try and assign into things they're not supposed to modify.

Avoid const_cast<> like the plague. There are one or two legitimate use cases for it, but they are very few and far between. If you're trying to change a const object, you'll do a lot better to find whoever declared it const in the first pace and talk the matter over with them to reach a consensus as to what should happen.

Which leads very neatly into assignments. You can assign into something only if it is non-const. If you want to assign into something that is const, see above. Remember that in the declarations int const *foo; and int * const bar; different things are const - other answers here have covered that issue admirably, so I won't go into it.

Function parameters:

Pass by value: e.g. void func(int param) you don't care one way or the other at the calling site. The argument can be made that there are use cases for declaring the function as void func(int const param) but that has no effect on the caller, only on the function itself, in that whatever value is passed cannot be changed by the function during the call.

Pass by reference: e.g. void func(int &param) Now it does make a difference. As just declared func is allowed to change param, and any calling site should be ready to deal with the consequences. Changing the declaration to void func(int const &param) changes the contract, and guarantees that func can now not change param, meaning what is passed in is what will come back out. As other have noted this is very useful for cheaply passing a large object that you don't want to change. Passing a reference is a lot cheaper than passing a large object by value.

Pass by pointer: e.g. void func(int *param) and void func(int const *param) These two are pretty much synonymous with their reference counterparts, with the caveat that the called function now needs to check for nullptr unless some other contractual guarantee assures func that it will never receive a nullptr in param.

Opinion piece on that topic. Proving correctness in a case like this is hellishly difficult, it's just too damn easy to make a mistake. So don't take chances, and always check pointer parameters for nullptr. You will save yourself pain and suffering and hard to find bugs in the long term. And as for the cost of the check, it's dirt cheap, and in cases where the static analysis built into the compiler can manage it, the optimizer will elide it anyway. Turn on Link Time Code Generation for MSVC, or WOPR (I think) for GCC, and you'll get it program wide, i.e. even in function calls that cross a source code module boundary.

At the end of the day all of the above makes a very solid case to always prefer references to pointers. They're just safer all round.

You need to escape the . because it has the meaning of "an arbitrary character" in a regular expression.

mystring = mystring.replace(/\./g,' ')

I found a workaround for recursive copying from remote to remote :

- name: List files in /usr/share/easy-rsa
  find:
    path: /usr/share/easy-rsa
    recurse: yes
    file_type: any
  register: find_result

- name: Create the directories
  file:
    path: "{{ item.path | regex_replace('/usr/share/easy-rsa','/etc/easy-rsa') }}"
    state: directory
    mode: "{{ item.mode }}"
  with_items:
    - "{{ find_result.files }}"
  when:
    - item.isdir

- name: Copy the files
  copy:
    src: "{{ item.path }}"
    dest: "{{ item.path | regex_replace('/usr/share/easy-rsa','/etc/easy-rsa') }}"
    remote_src: yes
    mode: "{{ item.mode }}"
  with_items:
    - "{{ find_result.files }}"
  when:
    - item.isdir == False

A nice code for the push_back and emplace_back is shown here.

You can see the move operation on push_back and not on emplace_back.

Run package declaration and body separately.

With PostgreSQL 9.5, this is now native functionality (like MySQL has had for several years):

INSERT ... ON CONFLICT DO NOTHING/UPDATE ("UPSERT")

9.5 brings support for "UPSERT" operations. INSERT is extended to accept an ON CONFLICT DO UPDATE/IGNORE clause. This clause specifies an alternative action to take in the event of a would-be duplicate violation.

...

Further example of new syntax:

INSERT INTO user_logins (username, logins)
VALUES ('Naomi',1),('James',1) 
ON CONFLICT (username)
DO UPDATE SET logins = user_logins.logins + EXCLUDED.logins;

to get the items checked you can use CheckedItems or GetItemsChecked. I tried below code in .NET 4.5

Iterate through the CheckedItems collection. This will give you the item number in the list of checked items, not the overall list. So if the first item in the list is not checked and the second item is checked, the code below will display text like Checked Item 1 = MyListItem2.

//Determine if there are any items checked. 
if(chBoxListTables.CheckedItems.Count != 0)  
{
    //looped through all checked items and show results.
    string s = "";
    for (int x = 0; x < chBoxListTables.CheckedItems.Count; x++)
    {
        s = s + (x + 1).ToString() + " = " + chBoxListTables.CheckedItems[x].ToString()+ ", ";
    }
    MessageBox.Show(s);//show result
}

-OR-

Step through the Items collection and call the GetItemChecked method for each item. This will give you the item number in the overall list, so if the first item in the list is not checked and the second item is checked, it will display something like Item 2 = MyListItem2.

int i;  
string s;   
s = "Checked items:\n" ;  
for (i = 0; i < checkedListBox1.Items.Count; i++)  
{  
   if (checkedListBox1.GetItemChecked(i))  
   {  
      s = s + "Item " + (i+1).ToString() + " = " + checkedListBox1.Items[i].ToString() + "\n";  
   }  
}  
MessageBox.Show (s);

Hope this helps...

This is specific to Windows. I was facing the same issue where I have to kill one specific java program using taskkill. When I run the java program, tasklist was showing the same program with Image name set as java.exe. But killing it using taskkill /F java.exe will stop all other java applications other than intended one which is not required.

So I run the same java program using:

start "MyProgramName" java java-program..

Here start command will open a new window and run the java program with window's title set to MyProgramName.

Now to kill this java-program use the following taskkill command:

taskkill /fi "MyProgramName"

Your Java program will be killed only. Rest will be unaffected.

You have to include the expression for your calculated column:

SELECT  
ColumnA,  
ColumnB,  
ColumnA + ColumnB AS calccolumn1  
(ColumnA + ColumnB) / ColumnC AS calccolumn2

Forge's SHA-256 implementation is fast and reliable.

To run tests on several SHA-256 JavaScript implementations, go to http://brillout.github.io/test-javascript-hash-implementations/.

The results on my machine suggests forge to be the fastest implementation and also considerably faster than the Stanford Javascript Crypto Library (sjcl) mentioned in the accepted answer.

Forge is 256 KB big, but extracting the SHA-256 related code reduces the size to 4.5 KB, see https://github.com/brillout/forge-sha256

• #include <> is for predefined header files

If the header file is predefined then you would simply write the header file name in angular brackets, and it would look like this (assuming we have a predefined header file name iostream):

#include <iostream>

• #include " " is for header files the programmer defines

If you (the programmer) wrote your own header file then you would write the header file name in quotes. So, suppose you wrote a header file called myfile.h, then this is an example of how you would use the include directive to include that file:

#include "myfile.h"

false == 0 and true = !false

i.e. anything that is not zero and can be converted to a boolean is not false, thus it must be true.

Some examples to clarify:

if(0)          // false
if(1)          // true
if(2)          // true
if(0 == false) // true
if(0 == true)  // false
if(1 == false) // false
if(1 == true)  // true
if(2 == false) // false
if(2 == true)  // false
cout << false  // 0
cout << true   // 1

true evaluates to 1, but any int that is not false (i.e. 0) evaluates to true but is not equal to true since it isn't equal to 1.

You can do the following:

1. add to your urlpatterns (r'^/accounts/password/reset/$', password_reset)
2. put your template in '/templates/registration/password_reset_form.html'
3. make your app come before 'django.contrib.auth' in INSTALLED_APPS

Explanation:

When the templates are loaded, they are searched in your INSTALLED_APPS variable in settings.py . The order is dictated by the definition's rank in INSTALLED_APPS, so since your app come before 'django.contrib.auth' your template were loaded (reference: https://docs.djangoproject.com/en/dev/ref/templates/api/#django.template.loaders.app_directories.Loader).

Motivation of approach:

1. I want be more dry and don't repeat for any view(defined by django) the template name (they are already defined in django)
2. I want a smallest url.py

Probably not what you want to hear, but a "feeds" table would be a great middleman for this sort of transaction, giving you a denormalized way of pivoting to all these data with a polymorphic relationship.

You could build it like this:

<?php

Schema::create('feeds', function($table) {
    $table->increments('id');
    $table->timestamps();
    $table->unsignedInteger('user_id');
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    $table->morphs('target'); 
});

Build the feed model like so:

<?php

class Feed extends Eloquent
{
    protected $fillable = ['user_id', 'target_type', 'target_id'];

    public function user()
    {
        return $this->belongsTo('User');
    }

    public function target()
    {
        return $this->morphTo();
    }
}

Then keep it up to date with something like:

<?php

Vote::created(function(Vote $vote) {
    $target_type = 'Vote';
    $target_id   = $vote->id;
    $user_id     = $vote->user_id;

    Feed::create(compact('target_type', 'target_id', 'user_id'));
});

You could make the above much more generic/robust—this is just for demonstration purposes.

At this point, your feed items are really easy to retrieve all at once:

<?php

Feed::whereIn('user_id', $my_friend_ids)
    ->with('user', 'target')
    ->orderBy('created_at', 'desc')
    ->get();

You can also use this script to figure out more info:

EXEC sp_server_info

The result will be something like that:

attribute_id | attribute_name        | attribute_value
-------------|-----------------------|-----------------------------------
           1 | DBMS_NAME             | Microsoft SQL Server
           2 | DBMS_VER              | Microsoft SQL Server 2012 - 11.0.6020.0
          10 | OWNER_TERM            | owner
          11 | TABLE_TERM            | table
          12 | MAX_OWNER_NAME_LENGTH | 128
          13 | TABLE_LENGTH          | 128
          14 | MAX_QUAL_LENGTH       | 128
          15 | COLUMN_LENGTH         | 128
          16 | IDENTIFIER_CASE       | MIXED
           ?  ?                       ?
           ?  ?                       ?
           ?  ?                       ?

You can add --force-with-lease to the command, it will works.

git push --force-with-lease

--force is destructive because it unconditionally overwrites the remote repository with whatever you have locally. But --force-with-lease ensure you don't overwrite other's work.

See more info here.

It doesn't exist at first. You have to create it in your home folder, /Users/usename/.m2/ (or ~/.m2)

For example :

I had downloaded it from http://gradle.org/gradle-download/. I use Homebrew, but I missed installing gradle using it.

To save some MBs by downloading it over again using Homebrew, I symlinked the gradle binary from the downloaded (and extracted) zip archive in the /usr/local/bin/. This is the same place where Homebrew symlinks all other binaries.

cd /usr/local/bin/
ln -s ~/Downloads/gradle-2.12/bin/gradle

Now check whether it works or not:

gradle -v

Two different issues here:

• Set the formatOutput and preserveWhiteSpace attributes to TRUE to generate formatted XML:

  $doc->formatOutput = TRUE;
  $doc->preserveWhiteSpace = TRUE;
  

• Many web browsers (namely Internet Explorer and Firefox) format XML when they display it. Use either the View Source feature or a regular text editor to inspect the output.

See also xmlEncoding and encoding.

In case you are working with seaborn plots, instead of Matplotlib, you can save a .png image like this:

Let's suppose you have a matrix object (either Pandas or NumPy), and you want to take a heatmap:

import seaborn as sb

image = sb.heatmap(matrix)   # This gets you the heatmap
image.figure.savefig("C:/Your/Path/ ... /your_image.png")   # This saves it

This code is compatible with the latest version of Seaborn. Other code around Stack Overflow worked only for previous versions.

Another way I like is this. I set the size of the next image as follows:

plt.subplots(figsize=(15,15))

And then later I plot the output in the console, from which I can copy-paste it where I want. (Since Seaborn is built on top of Matplotlib, there will not be any problem.)

Late for the answer but here are the list of things which I tried.So it will be in one place if anyone wants to try to fix the issue.

1. Valid architecture = armv7 armv7s
2. Build Active Architecture only = NO
3. Target -> Build Settings ->Other Linker Flags = $(inherited)
4. Target -> Build Settings ->Library Search Path = $(inherited)
5. Product Clean
6. Pod Update in terminal

If you look at the down arrow in environment tab. The attached file can appear multiple times. You may need to highlight and run detach(filename) several times until all cases are gone then attach(newfilename) should have no output message.

1. Create new blank table with the same structure

2. Execute query like this

   INSERT INTO tc_category1
   SELECT *
   FROM tc_category
   GROUP BY category_id, application_id
   HAVING count(*) > 1
   

3. Then execute this query

   INSERT INTO tc_category1
   SELECT *
   FROM tc_category
   GROUP BY category_id, application_id
   HAVING count(*) = 1
   

The keyCode is deprecated you can use key property in the KeyboardEvent

<textarea (keydown)=onKeydownEvent($event)></textarea>

Typescript:

onKeydownEvent($event: KeyboardEvent){

    // you can use the following for checkig enter key pressed or not
    if ($event.key === 'Enter') {
      console.log($event.key); // Enter
    }


    if ($event.key === 'Enter' && event.shiftKey) {
           //This is 'Shift+Enter' 
    }
}

You can create them just the way others have mentioned. One more point to add: You can even create a skewed two-dimensional array with each row, not necessarily having the same number of collumns, like this:

int array[][] = new int[3][];
array[0] = new int[3];
array[1] = new int[2];
array[2] = new int[5];

You could use Role Strategy plugin for that purpose. It works like a charm, just setup some roles and assign them. Even on project-specific level.

To have multiple Xcode instances installed you can put them to different folders for example /Developer5.0.2/Xcode, but to use them in CI or build environment(command line) you need to setup some environment variables during the build. You can have more instructions here. So it is working not just with beta and fresh release, also it's working for the really old versions, you might need it to use with Marmalade or Unity plugins which is not support the latest Xcode versions yet(some times it's happens).

In some systems, attempts to speed up the assembly of fully resolved '.c' files call the pre-assembly of include files "compiling header files". However, it is an optimization technique that is not necessary for actual C development.

Such a technique basically computed the include statements and kept a cache of the flattened includes. Normally the C toolchain will cut-and-paste in the included files recursively, and then pass the entire item off to the compiler. With a pre-compiled header cache, the tool chain will check to see if any of the inputs (defines, headers, etc) have changed. If not, then it will provide the already flattened text file snippets to the compiler.

Such systems were intended to speed up development; however, many such systems were quite brittle. As computers sped up, and source code management techniques changed, fewer of the header pre-compilers are actually used in the common project.

Until you actually need compilation optimization, I highly recommend you avoid pre-compiling headers.

Judge by yesterday's weather. How long did it take last time? Are you trending longer or shorter? Each shop is different.

Most agile shops need a lot less time, have drastically fewer defects, and quicker time to resolve them because of TDD. Even so, most agile shops have some measurable time spent with testing/QC.

If this is the first test run for this application, then the answer is "lets see" followed by an attempt. It depends on how quick you can get questions answered, - how testable it is, - how many features/functions - how many defects are discovered, - how quickly issues are resolved, - how many times the code cycles through testing, and - how many times testing is blocked by bugs. There is no way to tell. You could call it 50% or 175% or more, and not be wrong. Why not make a rough guess and multiply by Pi? It won't be much worse than any other answer you can make up.

You should (must) know how long it takes now and whether it's getting faster or slower, and whether the coverage is increasing or decreasing. With those three bits of information, you should be able to guess quite well.

    $.post(url, $.param($(this).serializeArray()), function(data) {

The following answer is a small improvement based upon qwertzguy's answer.

double density = getResources().getDisplayMetrics().density;
if (density >= 4.0) {
   //"xxxhdpi";
}
else if (density >= 3.0 && density < 4.0) {
   //xxhdpi
}
else if (density >= 2.0) {
   //xhdpi
}
else if (density >= 1.5 && density < 2.0) {
   //hdpi
}
else if (density >= 1.0 && density < 1.5) {
   //mdpi
}

$userRecord = Model::where([['email','=',$email],['password','=', $password]])->first();

or

$userRecord = self::where([['email','=',$email],['password','=', $password]])->first();

I` think this condition is better then 2 where. Its where condition array in array of where conditions;

While I agree with Ari's answer (and upvoted it :), I needed to do an extra step to get it to work with Java on Windows (where it needed to be deployed):

openssl s_client -showcerts -connect www.example.com:443 < /dev/null | openssl x509 -outform DER > derp.der

Before adding the openssl x509 -outform DER conversion, I was getting an error from keytool on Windows complaining about the certificate's format. Importing the .der file worked fine.

1 gotcha: when you use "p" to put the line, it puts it after the line your cursor is on, so if you want to add the line after the line you're yanking, don't move the cursor down a line before putting the new line.

You can access the window object as an associative array and set it that way

window["onlyVideo"] = "TEST";
document.write(onlyVideo);

If you just want the content as string, then the simple solution is to use the ReadFile function from the io/ioutil package. This function returns a slice of bytes which you can easily convert to a string.

package main

import (
    "fmt"
    "io/ioutil"
)

func main() {
    b, err := ioutil.ReadFile("file.txt") // just pass the file name
    if err != nil {
        fmt.Print(err)
    }

    fmt.Println(b) // print the content as 'bytes'

    str := string(b) // convert content to a 'string'

    fmt.Println(str) // print the content as a 'string'
}

You will want to use the YYYYMMDD for unambiguous date determination in SQL Server.

insert into table1(approvaldate)values('20120618 10:34:09 AM');

If you are married to the dd-mm-yy hh:mm:ss xm format, you will need to use CONVERT with the specific style.

insert into table1 (approvaldate)
       values (convert(datetime,'18-06-12 10:34:09 PM',5));

5 here is the style for Italian dates. Well, not just Italians, but that's the culture it's attributed to in Books Online.

Class.getResources would retrieve the resource by the classloader which load the object. While ClassLoader.getResource would retrieve the resource using the classloader specified.

Converting Integer to Long Very Simple and many ways to converting that
Example 1

 new Long(your_integer);

Example 2

Long.valueOf(your_integer); 

Example 3

Long a = 12345L;

Example 4
If you already have the int typed as an Integer you can do this:

Integer y = 12;
long x = y.longValue();

create constant file with any name like my_constants.py declare constant like that

CONSTANT_NAME = "SOME VALUE"

For accessing constant in your code import file like that

import my_constants as constant

and access the constant value as -

constant.CONSTANT_NAME

Just to suggest an alternative that does not involve the need to manually invoke a listener event:

Whatever your event listener does, move it into a function and call that function from the event listener.

Then, you can also call that function anywhere else that you need to accomplish the same thing that the event does when it fires.

I find this less "code intensive" and easier to read.

Dim celltxt As String
Range("C6").Select
Selection.End(xlToRight).Select
celltxt = Selection.Text
If InStr(1, celltext, "TOTAL") > 0 Then
Range("C7").Select 
Selection.End(xlToRight).Select
Selection.Value = "-"
End If

You declared "celltxt" and used "celltext" in the instr.

As indicated here, JavaFX is no longer included in openjdk.

So check, if you have <Java SDK root>/jre/lib/ext/jfxrt.jar on your classpath under Project Structure -> SDKs -> 1.x -> Classpath? If not, that could be why. Try adding it and see if that fixes your issue, e.g. on Ubuntu, install then openjfx package with sudo apt-get install openjfx.

Javascript 1.7 added destructured assignment which allows you to do essentially what you are after.

function getTuple(){
   return ["Bob", 24];
}
var [a, b] = getTuple();
// a === "bob" , b === 24 are both true

The error seems clear: model objects do not support item assignment. MyModel.objects.latest('id')['foo'] = 'bar' will throw this same error.

It's a little confusing that your model instance is called projectForm...

To reproduce your first block of code in a loop, you need to use setattr

for k,v in session_results.iteritems():
    setattr(projectForm, k, v)

I think it should be "there can only be one NON-STATIC top level public class per .java file". Isn't it?

Old answer:

Try using this URL: http://translate.google.com/translate_tts?tl=en&q=Hello%20World It will automatically generate a wav file which you can easily get with an HTTP request through any .net programming.

Edit:

Ohh Google, you thought you could prevent people from using your wonderful service with flimsy http header verification.

Here is a solution to get a response in multiple languages (I'll try to add more as we go):

NodeJS

// npm install `request`
const fs = require('fs');
const request = require('request');
const text = 'Hello World';

const options = {
    url: `https://translate.google.com/translate_tts?ie=UTF-8&q=${encodeURIComponent(text)}&tl=en&client=tw-ob`,
    headers: {
        'Referer': 'http://translate.google.com/',
        'User-Agent': 'stagefright/1.2 (Linux;Android 5.0)'
    }
}

request(options)
    .pipe(fs.createWriteStream('tts.mp3'))

Curl

curl 'https://translate.google.com/translate_tts?ie=UTF-8&q=Hello%20Everyone&tl=en&client=tw-ob' -H 'Referer: http://translate.google.com/' -H 'User-Agent: stagefright/1.2 (Linux;Android 5.0)' > google_tts.mp3

Note that the headers are based on @Chris Cirefice's example, if they stop working at some point I'll attempt to recreate conditions for this code to function. All credits for the current headers go to him and the wonderful tool that is WireShark. (also thanks to Google for not patching this)

Try:

var text = "'" + "http://example.com" + "'";

I think this is what you're after?

.shadow {_x000D_
  -webkit-box-shadow: 0 0 0 4px white, 0 6px 4px black;_x000D_
  -moz-box-shadow: 0 0 0 4px white, 0 6px 4px black;_x000D_
  box-shadow: 0 0 0 4px white, 0 6px 4px black;_x000D_
}

<div class="shadow">wefwefwef</div>

.catch(error => { throw error}) is a no-op. It results in unhandled rejection in route handler.

As explained in this answer, Express doesn't support promises, all rejections should be handled manually:

router.get("/emailfetch", authCheck, async (req, res, next) => {
  try {
  //listing messages in users mailbox 
    let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
    emailFetch = emailFetch.data
    res.send(emailFetch)
  } catch (err) {
    next(err);
  }
})

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

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

SET @DatabasesCursor = Cursor FOR

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

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

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

   --Print @vchDynamicQuery
   EXEC(@vchDynamicQuery)

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

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

There is another way if all you want is the text up to the first line feed:

x='some
thing'

y=${x%$'\n'*}

After that y will contain some and nothing else (no line feed).

What is happening here?

We perform a parameter expansion substring removal (${PARAMETER%PATTERN}) for the shortest match up to the first ANSI C line feed ($'\n') and drop everything that follows (*).

The full list of readyState values is:

State  Description
0      The request is not initialized
1      The request has been set up
2      The request has been sent
3      The request is in process
4      The request is complete

(from https://www.w3schools.com/js/js_ajax_http_response.asp)

In practice you almost never use any of them except for 4.

Some XMLHttpRequest implementations may let you see partially received responses in responseText when readyState==3, but this isn't universally supported and shouldn't be relied upon.

You can use display:inline-block with white-space:nowrap. Write like this:

.scrolls {
    overflow-x: scroll;
    overflow-y: hidden;
    height: 80px;
    white-space:nowrap
}
.imageDiv img {
    box-shadow: 1px 1px 10px #999;
    margin: 2px;
    max-height: 50px;
    cursor: pointer;
    display:inline-block;
    *display:inline;/* For IE7*/
    *zoom:1;/* For IE7*/
    vertical-align:top;
 }

Check this http://jsfiddle.net/YbrX3/

This is the setup I use:

Before running the tests, execute:

export DISPLAY=:99
/etc/init.d/xvfb start

And after the tests:

/etc/init.d/xvfb stop

The init.d file I use looks like this:

#!/bin/bash

XVFB=/usr/bin/Xvfb
XVFBARGS="$DISPLAY -ac -screen 0 1024x768x16"
PIDFILE=${HOME}/xvfb_${DISPLAY:1}.pid
case "$1" in
  start)
    echo -n "Starting virtual X frame buffer: Xvfb"
    /sbin/start-stop-daemon --start --quiet --pidfile $PIDFILE --make-pidfile --background --exec $XVFB -- $XVFBARGS
    echo "."
    ;;
  stop)
    echo -n "Stopping virtual X frame buffer: Xvfb"
    /sbin/start-stop-daemon --stop --quiet --pidfile $PIDFILE
    echo "."
    ;;
  restart)
    $0 stop
    $0 start
    ;;
  *)
  echo "Usage: /etc/init.d/xvfb {start|stop|restart}"
  exit 1
esac
exit 0

A "BEFORE-INSERT"-trigger is the only way to realize same-table updates on an insert, and is only possible from MySQL 5.5+. However, the value of an auto-increment field is only available to an "AFTER-INSERT" trigger - it defaults to 0 in the BEFORE-case. Therefore the following example code which would set a previously-calculated surrogate key value based on the auto-increment value id will compile, but not actually work since NEW.id will always be 0:

create table products(id int not null auto_increment, surrogatekey varchar(10), description text);
create trigger trgProductSurrogatekey before insert on product
for each row set NEW.surrogatekey = 
  (select surrogatekey from surrogatekeys where id = NEW.id);

You can use parseInt() but, as mentioned, the radix (base) should be specified:

x = parseInt(x, 10);
y = parseInt(y, 10);

10 means a base-10 number.

See this link for an explanation of why the radix is necessary.

Put the entire script into a template string, with {SERVERNAME} placeholders. Then edit the string using:

SET @SQL_SCRIPT = REPLACE(@TEMPLATE, '{SERVERNAME}', @DBNAME)

and then run it with

EXECUTE (@SQL_SCRIPT)

It's hard to believe that, in the course of three years, nobody noticed that my code doesn't work!

You can't EXEC multiple batches. GO is a batch separator, not a T-SQL statement. It's necessary to build three separate strings, and then to EXEC each one after substitution.

I suppose one could do something "clever" by breaking the single template string into multiple rows by splitting on GO; I've done that in ADO.NET code.

And where did I get the word "SERVERNAME" from?

Here's some code that I just tested (and which works):

DECLARE @DBNAME VARCHAR(255)
SET @DBNAME = 'TestDB'

DECLARE @CREATE_TEMPLATE VARCHAR(MAX)
DECLARE @COMPAT_TEMPLATE VARCHAR(MAX)
DECLARE @RECOVERY_TEMPLATE VARCHAR(MAX)

SET @CREATE_TEMPLATE = 'CREATE DATABASE {DBNAME}'
SET @COMPAT_TEMPLATE='ALTER DATABASE {DBNAME} SET COMPATIBILITY_LEVEL = 90'
SET @RECOVERY_TEMPLATE='ALTER DATABASE {DBNAME} SET RECOVERY SIMPLE'

DECLARE @SQL_SCRIPT VARCHAR(MAX)

SET @SQL_SCRIPT = REPLACE(@CREATE_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

SET @SQL_SCRIPT = REPLACE(@COMPAT_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

SET @SQL_SCRIPT = REPLACE(@RECOVERY_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

You can detect the IE browser by this way.

(navigator.userAgent.toLowerCase().indexOf('msie 6') != -1)

you can get reference on this URL: jquery.browser.msie Alternative

Prefix you literal with 0b like in

int i = 0b11111111;

See here.

This will make folder in sdcard with Folder name you provide.

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Folder name");
        if (!file.exists()) {
            file.mkdirs();
        }

A lot of the answers here so far are Chrome only or incur an HTTP overhead penalty. The solution that we are using is a little different:

1. Add a new object to the manifest content_scripts list like so:

{
  "matches": ["https://www.yoursite.com/*"],
  "js": [
    "install_notifier.js"
  ],
  "run_at": "document_idle"
}

This will allow the code in install_notifier.js to run on that site (if you didn't already have permissions there).

2. Send a message to every site in the manifest key above.

Add something like this to install_notifier.js (note that this is using a closure to keep the variables from being global, but that's not strictly necessary):

// Dispatch a message to every URL that's in the manifest to say that the extension is
// installed.  This allows webpages to take action based on the presence of the
// extension and its version. This is only allowed for a small whitelist of
// domains defined in the manifest.
(function () {
  let currentVersion = chrome.runtime.getManifest().version;
  window.postMessage({
    sender: "my-extension",
    message_name: "version",
    message: currentVersion
  }, "*");
})();

Your message could say anything, but it's useful to send the version so you know what you're dealing with. Then...

3. On your website, listen for that message.

Add this to your website somewhere:

window.addEventListener("message", function (event) {
  if (event.source == window &&
    event.data.sender &&
    event.data.sender === "my-extension" &&
    event.data.message_name &&
    event.data.message_name === "version") {
    console.log("Got the message");
  }
});

This works in Firefox and Chrome, and doesn't incur HTTP overhead or manipulate the page.

By doing so you'd be able to control any action of the framed page, which you cannot. Same-domain origin policy applies.

A static variable stays in the memory for the entire lifetime of the application, and is initialised during class loading. A non-static variable is being initialised each time you construct a new object. It's generally better to use:

private static final int NUMBER = 10;

Why? This reduces the memory footprint per instance. It possibly is also favourable for cache hits. And it just makes sense: static should be used for things that are shared across all instances (a.k.a. objects) of a certain type (a.k.a. class).

Disabling SQL Net Banners saved us.

I know you said that you tried already setting permissions to 777, but as I have an evidence that for me it was a permission issue I'm posting what I exactly run hoping it can help. Here is my experience:

Just fix the height of the image & provide width = auto

img{
    height: 95vh;
    width: auto;
}

Instead of:

int count = 0;
for (int i = 0; i<args.length -1; ++i)
    count++;
System.out.println(count);

 }

you can just

int count = args.length;

The average is the sum of your args divided by the number of your args.

int res = 0;
int count = args.lenght;

for (int a : args)
{
res += a;
}
res /= count;

you can make this code shorter too, i'll let you try and ask if you need help!

This is my first answerso tell me if something wrong!

Although both of them will fetch the same results, there is a significant difference in the performance of both the functions. reduceByKey() works better with larger datasets when compared to groupByKey().

In reduceByKey(), pairs on the same machine with the same key are combined (by using the function passed into reduceByKey()) before the data is shuffled. Then the function is called again to reduce all the values from each partition to produce one final result.

In groupByKey(), all the key-value pairs are shuffled around. This is a lot of unnecessary data to being transferred over the network.

Starting from freemarker 2.3.7, you can use this syntax :

${(object.attribute)!}

or, if you want display a default text when the attribute is null :

${(object.attribute)!"default text"}

The answer with most votes is very concise and clean, but it can have false positives when a space is part of one of the array elements. This can be overcome when changing IFS and using "${array[*]}" instead of "${array[@]}". The method is identical, but it looks less clean. By using "${array[*]}", we print all elements of $array, separated by the first character in IFS. So by choosing a correct IFS, you can overcome this particular issue. In this particular case, we decide to set IFS to an uncommon character $'\001' which stands for Start of Heading (SOH)

$ array=("foo bar" "baz" "qux")
$ IFS=$'\001'
$ [[ "$IFS${array[*]}$IFS" =~ "${IFS}foo${IFS}" ]] && echo yes || echo no
no
$ [[ "$IFS${array[*]}$IFS" =~ "${IFS}foo bar${IFS}" ]] && echo yes || echo no
yes
$ unset IFS

This resolves most issues false positives, but requires a good choice of IFS.

note: If IFS was set before, it is best to save it and reset it instead of using unset IFS

In /config/environments/production.rb I had to add this:

Rails.application.config.assets.precompile += %w( *.js ^[^_]*.css *.css.erb )

The .js was getting precompiled already, but I added it anyway. The .css and .css.erb apparently don't happen automatically. The ^[^_] excludes partials from being compiled -- it's a regexp.

It's a little frustrating that the docs clearly state that asset pipeline IS enabled by default but doesn't clarify the fact that only applies to javascripts.

The easiest solution is to simply style the element you're inserting the text into with the following CSS property:

white-space: pre-wrap;

This property causes whitespace and newlines within the matching elements to be treated in the same way as inside a <textarea>. That is, consecutive whitespace is not collapsed, and lines are broken at explicit newlines (but are also wrapped automatically if they exceed the width of the element).

Given that several of the answers posted here so far have been vulnerable to HTML injection (e.g. because they assign unescaped user input to innerHTML) or otherwise buggy, let me give an example of how to do this safely and correctly, based on your original code:

document.getElementById('post-button').addEventListener('click', function () {_x000D_
  var post = document.createElement('p');_x000D_
  var postText = document.getElementById('post-text').value;_x000D_

  cardStack.prepend(card);_x000D_
});

Note that, like your original code, the snippet above uses append() and prepend(). As of this writing, those functions are still considered experimental and not fully supported by all browsers. If you want to be safe and remain compatible with older browsers, you can substitute them pretty easily as follows:

• element.append(otherElement) can be replaced with element.appendChild(otherElement);
• element.prepend(otherElement) can be replaced with element.insertBefore(otherElement, element.firstChild);
• element.append(stringOfText) can be replaced with element.appendChild(document.createTextNode(stringOfText));
• element.prepend(stringOfText) can be replaced with element.insertBefore(document.createTextNode(stringOfText), element.firstChild);
• as a special case, if element is empty, both element.append(stringOfText) and element.prepend(stringOfText) can simply be replaced with element.textContent = stringOfText.

Here's the same snippet as above, but without using append() or prepend():

document.getElementById('post-button').addEventListener('click', function () {_x000D_
  var post = document.createElement('p');_x000D_
  var postText = document.getElementById('post-text').value;_x000D_
  post.textContent = postText;_x000D_
  var card = document.createElement('div');_x000D_
  card.appendChild(post);_x000D_
  var cardStack = document.getElementById('card-stack');_x000D_
  cardStack.insertBefore(card, cardStack.firstChild);_x000D_
});

Ps. If you really want to do this without using the CSS white-space property, an alternative solution would be to explicitly replace any newline characters in the text with <br> HTML tags. The tricky part is that, to avoid introducing subtle bugs and potential security holes, you have to first escape any HTML metacharacters (at a minimum, & and <) in the text before you do this replacement.

Probably the simplest and safest way to do that is to let the browser handle the HTML-escaping for you, like this:

var post = document.createElement('p');
post.textContent = postText;
post.innerHTML = post.innerHTML.replace(/\n/g, '<br>\n');

document.getElementById('post-button').addEventListener('click', function () {_x000D_
  var post = document.createElement('p');_x000D_
  var postText = document.getElementById('post-text').value;_x000D_
  post.textContent = postText;_x000D_
  post.innerHTML = post.innerHTML.replace(/\n/g, '<br>\n');  // <-- THIS FIXES THE LINE BREAKS_x000D_
  var card = document.createElement('div');_x000D_
  card.appendChild(post);_x000D_

Note that, while this will fix the line breaks, it won't prevent consecutive whitespace from being collapsed by the HTML renderer. It's possible to (sort of) emulate that by replacing some of the whitespace in the text with non-breaking spaces, but honestly, that's getting rather complicated for something that can be trivially solved with a single line of CSS.

Try these functions,

var JsonToArray = function(json)
{
    var str = JSON.stringify(json, null, 0);
    var ret = new Uint8Array(str.length);
    for (var i = 0; i < str.length; i++) {
        ret[i] = str.charCodeAt(i);
    }
    return ret
};

var binArrayToJson = function(binArray)
{
    var str = "";
    for (var i = 0; i < binArray.length; i++) {
        str += String.fromCharCode(parseInt(binArray[i]));
    }
    return JSON.parse(str)
}

Rule 1: You can not add a new table without specifying the primary key constraint[not a good practice if you create it somehow]. So the code:

CREATE TABLE transactions( 
id int NOT NULL AUTO_INCREMENT, 
location varchar(50) NOT NULL, 
description varchar(50) NOT NULL, 
category varchar(50) NOT NULL, 
amount double(10,9) NOT NULL, 
type varchar(6) NOT NULL,  
notes varchar(512), 
receipt int(10), 
PRIMARY KEY(id));

Rule 2: You are not allowed to use the keywords(words with predefined meaning) as a field name. Here type is something like that is used(commonly used with Join Types). So the code:

CREATE TABLE transactions( 
id int NOT NULL AUTO_INCREMENT, 
location varchar(50) NOT NULL, 
description varchar(50) NOT NULL, 
category varchar(50) NOT NULL, 
amount double(10,9) NOT NULL, 
transaction_type varchar(6) NOT NULL,  
notes varchar(512), 
receipt int(10), 
PRIMARY KEY(id));

Now you please try with this code. First check it in your database user interface(I am running HeidiSQL, or you can try it in your xampp/wamp server also)and make sure this code works. Now delete the table from your db and execute the code in your program. Thank You.

Yes, you can set the line height after defining the border like this:

border-right: 1px solid;
line-height: 10px;

I have observed one case when eclipse when in forced quit, or Alt-f2 xkilled in linux, an attempt to immediately open eclipse shows that error. Even the metadat/.lock file is not present in that case. However it starts working after a span of about two minutes

More compact version working with spaces and newlines in the file name:

find . -iname '*.txt' -exec sh -c 'echo "{}" ; ls -l "{}"' \;

Use this icons with bootstrap (glyphicon):

<span class="glyphicon glyphicon-triangle-bottom"></span>
<span class="glyphicon glyphicon-triangle-top"></span>

It specifies the size of the log file to trigger rotation. For example size 50M will trigger a log rotation once the file is 50MB or greater in size. You can use the suffix M for megabytes, k for kilobytes, and G for gigabytes. If no suffix is used, it will take it to mean bytes. You can check the example at the end. There are three directives available size, maxsize, and minsize. According to manpage:

minsize size
              Log  files  are  rotated when they grow bigger than size bytes,
              but not before the additionally specified time interval (daily,
              weekly,  monthly, or yearly).  The related size option is simi-
              lar except that it is mutually exclusive with the time interval
              options,  and  it causes log files to be rotated without regard
              for the last rotation time.  When minsize  is  used,  both  the
              size and timestamp of a log file are considered.

size size
              Log files are rotated only if they grow bigger then size bytes.
              If size is followed by k, the size is assumed to  be  in  kilo-
              bytes.  If the M is used, the size is in megabytes, and if G is
              used, the size is in gigabytes. So size 100,  size  100k,  size
              100M and size 100G are all valid.
maxsize size
              Log files are rotated when they grow bigger than size bytes even before
              the additionally specified time interval (daily, weekly, monthly, 
              or yearly).  The related size option is  similar  except  that  it 
              is mutually exclusive with the time interval options, and it causes
              log files to be rotated without regard for the last rotation time.  
              When maxsize is used, both the size and timestamp of a log file are                  
              considered.

Here is an example:

"/var/log/httpd/access.log" /var/log/httpd/error.log {
           rotate 5
           mail [email protected]
           size 100k
           sharedscripts
           postrotate
               /usr/bin/killall -HUP httpd
           endscript
       }

Here is an explanation for both files /var/log/httpd/access.log and /var/log/httpd/error.log. They are rotated whenever it grows over 100k in size, and the old logs files are mailed (uncompressed) to [email protected] after going through 5 rotations, rather than being removed. The sharedscripts means that the postrotate script will only be run once (after the old logs have been compressed), not once for each log which is rotated. Note that the double quotes around the first filename at the beginning of this section allows logrotate to rotate logs with spaces in the name. Normal shell quoting rules apply, with ,, and \ characters supported.

Swift 4

AppDelegate

var orientationLock = UIInterfaceOrientationMask.all

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
    return self.orientationLock
}
struct AppUtility {
    static func lockOrientation(_ orientation: UIInterfaceOrientationMask) {
        if let delegate = UIApplication.shared.delegate as? AppDelegate {
            delegate.orientationLock = orientation
        }
    }

    static func lockOrientation(_ orientation: UIInterfaceOrientationMask, andRotateTo rotateOrientation:UIInterfaceOrientation) {
        self.lockOrientation(orientation)
        UIDevice.current.setValue(rotateOrientation.rawValue, forKey: "orientation")
    }
}

Your ViewController Add Following line if you need only portrait orientation. you have to apply this to all ViewController need to display portrait mode.

override func viewWillAppear(_ animated: Bool) {
AppDelegate.AppUtility.lockOrientation(UIInterfaceOrientationMask.portrait, andRotateTo: UIInterfaceOrientation.portrait)
    }

and that will make screen orientation for others Viewcontroller according to device physical orientation.

override func viewWillDisappear(_ animated: Bool) {
        AppDelegate.AppUtility.lockOrientation(UIInterfaceOrientationMask.all)

    }

<div style="overflow:auto">
    <table id="table2"></table>
</div>

Try this code for overflow table it will work only on div tag

If you know the range of the inputs (which you do since your function takes an int), you can precompute a table of primes less than or equal to the square root of the max input (2^31-1 in this case), and then test for divisibility by each prime in the table less than or equal to the square root of the number given.

Try this

$value = mysql_result($result, 0);

Have you tried setting the scroll direction of your UICollectionViewFlowLayout to horizontal?

[yourFlowLayout setScrollDirection:UICollectionViewScrollDirectionHorizontal];

And if you want it to page like springboard does, you'll need to enable paging on your collection view like so:

[yourCollectionView setPagingEnabled:YES];

Yes, you can specify which fields are serialized as JSON response and which to ignore. This is what you need to do to implement Dynamically ignore properties.

1) First, you need to add @JsonFilter from com.fasterxml.jackson.annotation.JsonFilter on your entity class as.

import com.fasterxml.jackson.annotation.JsonFilter;

@JsonFilter("SomeBeanFilter")
public class SomeBean {

  private String field1;

  private String field2;

  private String field3;

  // getters/setters
}

2) Then in your controller, you have to add create the MappingJacksonValue object and set filters on it and in the end, you have to return this object.

import java.util.Arrays;
import java.util.List;

import org.springframework.http.converter.json.MappingJacksonValue;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import com.fasterxml.jackson.databind.ser.FilterProvider;
import com.fasterxml.jackson.databind.ser.impl.SimpleBeanPropertyFilter;
import com.fasterxml.jackson.databind.ser.impl.SimpleFilterProvider;

@RestController
public class FilteringController {

  // Here i want to ignore all properties except field1,field2.
  @GetMapping("/ignoreProperties")
  public MappingJacksonValue retrieveSomeBean() {
    SomeBean someBean = new SomeBean("value1", "value2", "value3");

    SimpleBeanPropertyFilter filter = SimpleBeanPropertyFilter.filterOutAllExcept("field1", "field2");

    FilterProvider filters = new SimpleFilterProvider().addFilter("SomeBeanFilter", filter);

    MappingJacksonValue mapping = new MappingJacksonValue(someBean);

    mapping.setFilters(filters);

    return mapping;
  }
}

This is what you will get in response:

{
  field1:"value1",
  field2:"value2"
}

instead of this:

{
  field1:"value1",
  field2:"value2",
  field3:"value3"
}

Here you can see it ignores other properties(field3 in this case) in response except for property field1 and field2.

Hope this helps.

On Ubuntu you can simply add the most recent Apt repository and then run:

sudo apt-get install postgresql-client-11

For Mac OS X Mojave and above

To Uninstall Homebrew, run following command:

sudo ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

To Install Homebrew, run following command:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

And if you run into Permission denied issue, try running this command followed by install command again:

sudo chown -R $(whoami):admin /usr/local/* && sudo chmod -R g+rwx /usr/local/*

code that works, but output is:

10
20
30
40
50

so:

    List<Integer> myCoords = new ArrayList<Integer>();
    myCoords.add(10);
    myCoords.add(20);
    myCoords.add(30);
    myCoords.add(40);
    myCoords.add(50);
    for (Integer number : myCoords) {
        System.out.println(number);
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

In Windows, you should go: Start > Run > services.msc > Apache 2.4 > Properties > Start Mode > Automatic > Apply > Start > OK > [Same as MySQL]

Using async and await it is lot more easy.

router.post('/login',async (req, res, next) => {
i = await queries.checkUser(req.body);
console.log('i: '+JSON.stringify(i));
});

//User Available Check
async function checkUser(request) {
try {
    let response = await sql.query('select * from login where email = ?', 
    [request.email]);
    return response[0];

    } catch (err) {
    console.log(err);

  }

}

Here is a solution on pure js. You can do it with html5 saveAs. For example this lib could be helpful: https://github.com/eligrey/FileSaver.js
Look at the demo: http://eligrey.com/demos/FileSaver.js/
P.S. There is no information about json save, but you can do it changing file type to "application/json" and format to .json

How do I move a table into a schema in T-SQL

The best and the easiest ways to create a copy of a dict in both Python 2.7 and 3 are...

To create a copy of simple(single-level) dictionary:

1. Using dict() method, instead of generating a reference that points to the existing dict.

my_dict1 = dict()
my_dict1["message"] = "Hello Python"
print(my_dict1)  # {'message':'Hello Python'}

my_dict2 = dict(my_dict1)
print(my_dict2)  # {'message':'Hello Python'}

# Made changes in my_dict1 
my_dict1["name"] = "Emrit"
print(my_dict1)  # {'message':'Hello Python', 'name' : 'Emrit'}
print(my_dict2)  # {'message':'Hello Python'}

2. Using the built-in update() method of python dictionary.

my_dict2 = dict()
my_dict2.update(my_dict1)
print(my_dict2)  # {'message':'Hello Python'}

# Made changes in my_dict1 
my_dict1["name"] = "Emrit"
print(my_dict1)  # {'message':'Hello Python', 'name' : 'Emrit'}
print(my_dict2)  # {'message':'Hello Python'}

To create a copy of nested or complex dictionary:

Use the built-in copy module, which provides a generic shallow and deep copy operations. This module is present in both Python 2.7 and 3.*

import copy

my_dict2 = copy.deepcopy(my_dict1)

i had the same problem... every time that i wanted to publish my css.. I had to make a search/replace.. and relative path wouldnt work either for me because the relative paths were different from dev to production.

Finally was tired of doing the search/replace and I created a dynamic css, (e.g. www.mysite.com/css.php) it's the same but now i could use my php constants in the css. somethig like

.icon{
  background-image:url('<?php echo BASE_IMAGE;?>icon.png');
}

and it's not a bad idea to make it dynamic because now i could compress it using YUI compressor without loosing the original format on my dev server.

Good Luck!

Below is an example of the correct way I think. At least it is what I use. You need to do Response.Clear to get rid of any headers that are already populated. You need to pass the correct ContentType of text/xml. That is the way you serve xml. In general you want to serve it as charset UTF-8 as that is what most parsers are expecting. But I don't think it has to be that. But if you change it make sure to change your xml document declaration and indicate the charset in there. You need to use the XmlWriter so you can actually write in UTF-8 and not whatever charset is the default. And to have it properly encode your xml data in UTF-8.

I believe this is the easiest way to do it, also possible using through the inline style attribute within the <img> tag.

.scaled
{
  transform: scale(0.7); /* Equal to scaleX(0.7) scaleY(0.7) */
}

<img src="flower.png" class="scaled">

or

<img src="flower.png" style="transform: scale(0.7);">

You can create it like this

conda create --prefix C:/tensorflow2 python=3.7

and you don't have to move to that folder to activate it.

# To activate this environment, use:
# > activate C:\tensorflow2

As you see I do it like this.

D:\Development_Avector\PycharmProjects\TensorFlow>activate C:\tensorflow2

(C:\tensorflow2) D:\Development_Avector\PycharmProjects\TensorFlow>

(C:\tensorflow2) D:\Development_Avector\PycharmProjects\TensorFlow>conda --version

Below is the swift 3 version of the solution -

let dateAsString = "6:35:58 PM"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "h:mm:ss a"
let date = dateFormatter.date(from: dateAsString)

dateFormatter.dateFormat = "HH:mm:ss"
let date24 = dateFormatter.string(from: date!)
print(date24)

My Answer: All of the following should be overridden (i.e. describe them all within columndefinition, if appropriate):

• length
• precision
• scale
• nullable
• unique

i.e. the column DDL will consist of: name + columndefinition and nothing else.

Rationale follows.

1. Annotation containing the word "Column" or "Table" is purely physical - properties only used to control DDL/DML against database.

2. Other annotation purely logical - properties used in-memory in java to control JPA processing.

3. That's why sometimes it appears the optionality/nullability is set twice - once via @Basic(...,optional=true) and once via @Column(...,nullable=true). Former says attribute/association can be null in the JPA object model (in-memory), at flush time; latter says DB column can be null. Usually you'd want them set the same - but not always, depending on how the DB tables are setup and reused.

In your example, length and nullable properties are overridden and redundant.

So, when specifying columnDefinition, what other properties of @Column are made redundant?

1. In JPA Spec & javadoc:

   • columnDefinition definition: The SQL fragment that is used when generating the DDL for the column.

   • columnDefinition default: Generated SQL to create a column of the inferred type.

   • The following examples are provided:

     @Column(name="DESC", columnDefinition="CLOB NOT NULL", table="EMP_DETAIL")
     @Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL")
     

   • And, err..., that's it really. :-$ ?!

   Does columnDefinition override other properties provided in the same annotation?

   The javadoc and JPA spec don't explicity address this - spec's not giving great protection. To be 100% sure, test with your chosen implementation.

2. The following can be safely implied from examples provided in the JPA spec

   • name & table can be used in conjunction with columnDefinition, neither are overridden
   • nullable is overridden/made redundant by columnDefinition

3. The following can be fairly safely implied from the "logic of the situation" (did I just say that?? :-P ):

   • length, precision, scale are overridden/made redundant by the columnDefinition - they are integral to the type
   • insertable and updateable are provided separately and never included in columnDefinition, because they control SQL generation in-memory, before it is emmitted to the database.

4. That leaves just the "unique" property. It's similar to nullable - extends/qualifies the type definition, so should be treated integral to type definition. i.e. should be overridden.

Test My Answer For columns "A" & "B", respectively:

  @Column(name="...", table="...", insertable=true, updateable=false,
          columndefinition="NUMBER(5,2) NOT NULL UNIQUE"

  @Column(name="...", table="...", insertable=false, updateable=true,
          columndefinition="NVARCHAR2(100) NULL"

• confirm generated table has correct type/nullability/uniqueness
• optionally, do JPA insert & update: former should include column A, latter column B

I needed to rotate a 3D model around one of the three axes {x, y, z} in which that model was embedded and this was the top result for a search of how to do this in numpy. I used the following simple function:

def rotate(X, theta, axis='x'):
  '''Rotate multidimensional array `X` `theta` degrees around axis `axis`'''
  c, s = np.cos(theta), np.sin(theta)
  if axis == 'x': return np.dot(X, np.array([
    [1.,  0,  0],
    [0 ,  c, -s],
    [0 ,  s,  c]
  ]))
  elif axis == 'y': return np.dot(X, np.array([
    [c,  0,  -s],
    [0,  1,   0],
    [s,  0,   c]
  ]))
  elif axis == 'z': return np.dot(X, np.array([
    [c, -s,  0 ],
    [s,  c,  0 ],
    [0,  0,  1.],
  ]))

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

@Autowired
private Environment environment;
....

this.environment.getActiveProfiles();

I solved this case by using static Action

public class CatalogoModel 
{
    private String _Id;
    private String _Descripcion;
    private Boolean _IsChecked;

    public String Id
    {
        get { return _Id; }
        set { _Id = value; }
    }
    public String Descripcion
    {
        get { return _Descripcion; }
        set { _Descripcion = value; }
    }
    public Boolean IsChecked
    {
        get { return _IsChecked; }
        set
        {
           _IsChecked = value;
            NotifyPropertyChanged("IsChecked");
            OnItemChecked.Invoke();
        }
    }

    public static Action OnItemChecked;
} 

public class ReglaViewModel : ViewModelBase
{
    private ObservableCollection<CatalogoModel> _origenes;

    CatalogoModel.OnItemChecked = () =>
            {
                var x = Origenes.Count;  //Entra cada vez que cambia algo en _origenes
            };
}

You don't need negative lookahead. There is working example:

/([\s\S]*?)(red|green|blue|)/g

Description:

• [\s\S] - match any character
• * - match from 0 to unlimited from previous group
• ? - match as less as possible
• (red|green|blue|) - match one of this words or nothing
• g - repeat pattern

Example:

whiteredwhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredwhiteredwhiteredwhiteredwhiteredwhiteredgreenbluewhiteredwhiteredwhiteredwhiteredwhiteredredgreenredgreenredgreenredgreenredgreenbluewhiteredbluewhiteredbluewhiteredbluewhiteredbluewhiteredwhite

Will be:

Serial is not included with Python. It is a package that you'll need to install separately.

Since you have pip installed you can install serial from the command line with:

pip install pyserial

Or, you can use a Windows installer from here. It looks like you're using Python 3 so click the installer for Python 3.

Then you should be able to import serial as you tried before.

If you are fine using a graphical tool this works very well:

gitk <file>

gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!

var id = $(this).find('option:selected').attr('id');

then you do whatever you want with selectedIndex

I've reedited my answer ... since selectedIndex isn't a good variable to give example...

For the last 3+ years these are the functions that I am using for finding last row and last column per defined column(for row) and row(for column):

Last Column:

Function lastCol(Optional wsName As String, Optional rowToCheck As Long = 1) As Long

    Dim ws  As Worksheet

    If wsName = vbNullString Then
        Set ws = ActiveSheet
    Else
        Set ws = Worksheets(wsName)
    End If

    lastCol = ws.Cells(rowToCheck, ws.Columns.Count).End(xlToLeft).Column

End Function

Last Row:

Function lastRow(Optional wsName As String, Optional columnToCheck As Long = 1) As Long

    Dim ws As Worksheet

    If wsName = vbNullString Then
        Set ws = ActiveSheet
    Else
        Set ws = Worksheets(wsName)
    End If

    lastRow = ws.Cells(ws.Rows.Count, columnToCheck).End(xlUp).Row

End Function

For the case of the OP, this is the way to get the last row in column E:

Debug.Print lastRow(columnToCheck:=Range("E4:E48").Column)

Last Row, counting empty rows with data:

Here we may use the well-known Excel formulas, which give us the last row of a worksheet in Excel, without involving VBA - =IFERROR(LOOKUP(2,1/(NOT(ISBLANK(A:A))),ROW(A:A)),0)

In order to put this in VBA and not to write anything in Excel, using the parameters for the latter functions, something like this could be in mind:

Public Function LastRowWithHidden(Optional wsName As String, Optional columnToCheck As Long = 1) As Long

    Dim ws As Worksheet

    If wsName = vbNullString Then
        Set ws = ActiveSheet
    Else
        Set ws = Worksheets(wsName)
    End If

    Dim letters As String
    letters = ColLettersGenerator(columnToCheck)
    LastRowWithHidden = ws.Evaluate("=IFERROR(LOOKUP(2,1/(NOT(ISBLANK(" & letters & "))),ROW(" & letters & " )),0)")

End Function

Function ColLettersGenerator(col As Long) As String

    Dim result As Variant
    result = Split(Cells(1, col).Address(True, False), "$")
    ColLettersGenerator = result(0) & ":" & result(0)

End Function

I know an answer has already been accepted for this problem but someone asked in the comments if there was a solution that could be done outside the web.config. I had a ListView producing the exact same error and setting EnableViewState to false resolved this problem for me.

This takes smhg from here and curt's from Last index of a given substring in MySQL and combines them. This is for mysql, all I needed was to get a decent split of name to first_name last_name with the last name a single word, the first name everything before that single word, where the name could be null, 1 word, 2 words, or more than 2 words. Ie: Null; Mary; Mary Smith; Mary A. Smith; Mary Sue Ellen Smith;

So if name is one word or null, last_name is null. If name is > 1 word, last_name is last word, and first_name all words before last word.

Note that I've already trimmed off stuff like Joe Smith Jr. ; Joe Smith Esq. and so on, manually, which was painful, of course, but it was small enough to do that, so you want to make sure to really look at the data in the name field before deciding which method to use.

Note that this also trims the outcome, so you don't end up with spaces in front of or after the names.

I'm just posting this for others who might google their way here looking for what I needed. This works, of course, test it with the select first.

It's a one time thing, so I don't care about efficiency.

SELECT TRIM( 
    IF(
        LOCATE(' ', `name`) > 0,
        LEFT(`name`, LENGTH(`name`) - LOCATE(' ', REVERSE(`name`))),
        `name`
    ) 
) AS first_name,
TRIM( 
    IF(
        LOCATE(' ', `name`) > 0,
        SUBSTRING_INDEX(`name`, ' ', -1) ,
        NULL
    ) 
) AS last_name
FROM `users`;


UPDATE `users` SET
`first_name` = TRIM( 
    IF(
        LOCATE(' ', `name`) > 0,
        LEFT(`name`, LENGTH(`name`) - LOCATE(' ', REVERSE(`name`))),
        `name`
    ) 
),
`last_name` = TRIM( 
    IF(
        LOCATE(' ', `name`) > 0,
        SUBSTRING_INDEX(`name`, ' ', -1) ,
        NULL
    ) 
);

Use javascript

But it depends on what you are trying to do. If you just want to change the height and width, I suggest this:

{
document.getElementById('sample_id').style.height = '150px';
document.getElementById('sample_id').style.width = '150px';


}

TO totally remove it, remove the style, and then re-set the color:

getElementById('sample_id').removeAttribute("style");
document.getElementById('sample_id').style.color = 'red';

Of course, no the only question that remains is on which event you want this to happen.

I ended up using this code:

public void setMaximized(boolean maximized){
    if(maximized){
        DisplayMode mode = this.getGraphicsConfiguration().getDevice().getDisplayMode();
        Insets insets = Toolkit.getDefaultToolkit().getScreenInsets(this.getGraphicsConfiguration());
        this.setMaximizedBounds(new Rectangle(
                mode.getWidth() - insets.right - insets.left, 
                mode.getHeight() - insets.top - insets.bottom
        ));
        this.setExtendedState(this.getExtendedState() | JFrame.MAXIMIZED_BOTH);
    }else{
        this.setExtendedState(JFrame.NORMAL);
    }
}

This options worked the best of all the options, including multiple monitor support. The only flaw this has is that the taskbar offset is used on all monitors is some configurations.

Just style the content with white-space: pre-wrap;.

div {_x000D_
    white-space: pre-wrap;_x000D_
}

<div>_x000D_
This is some text   with some extra spacing    and a_x000D_
few newlines along with some trailing spaces        _x000D_
     and five leading spaces thrown in_x000D_
for                                              good_x000D_
measure                                              _x000D_
</div>

I found the following code easy and working. Original answer is here https://www.postgresql.org/message-id/[email protected]

prova=> create table test(t text, i integer);
CREATE

prova=> insert into test values('123',123);
INSERT 64579 1

prova=> select cast(i as text),cast(t as int)from test;

Question 1: Unfortunately the one in which you you say is most intuitive is the least used in Android. As I understand, you should separate your UI (XML) and computational functionality (Java Class Files). It also makes for easier debugging. It is actually a lot easier to read this way and think about Android imo.

Question 2: I believe the two mainly used are #2 and #3. I will use a Button clickButton as an example.

2

is in the form of an anonymous class.

Button clickButton = (Button) findViewById(R.id.clickButton);
clickButton.setOnClickListener( new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                ***Do what you want with the click here***
            }
        });

This is my favorite as it has the onClick method right next to where the button variable was set with the findViewById. It seems very neat and tidy that everything that deals with this clickButton Button View is located here.

A con that my coworker comments, is that imagine you have many views that need onclick listener. You can see that your onCreate will get very long in length. So that why he likes to use:

3

Say you have, 5 clickButtons:

Make sure your Activity/Fragment implement OnClickListener

// in OnCreate

Button mClickButton1 = (Button)findViewById(R.id.clickButton1);
mClickButton1.setOnClickListener(this);
Button mClickButton2 = (Button)findViewById(R.id.clickButton2);
mClickButton2.setOnClickListener(this);
Button mClickButton3 = (Button)findViewById(R.id.clickButton3);
mClickButton3.setOnClickListener(this);
Button mClickButton4 = (Button)findViewById(R.id.clickButton4);
mClickButton4.setOnClickListener(this);
Button mClickButton5 = (Button)findViewById(R.id.clickButton5);
mClickButton5.setOnClickListener(this);


// somewhere else in your code

public void onClick(View v) {
    switch (v.getId()) {
        case  R.id.clickButton1: {
            // do something for button 1 click
            break;
        }

        case R.id.clickButton2: {
            // do something for button 2 click
            break;
        }

        //.... etc
    }
}

This way as my coworker explains is neater in his eyes, as all the onClick computation is handled in one place and not crowding the onCreate method. But the downside I see is, that the:

1. views themselves,
2. and any other object that might be located in onCreate used by the onClick method will have to be made into a field.

Let me know if you would like more information. I didn't answer your question fully because it is a pretty long question. And if I find some sites I will expand my answer, right now I'm just giving some experience.

In Ubuntu 14.04.2 LTS:

1. Go to Software Center and remove "IDLE(using Python-2.7)".

2. Install "IDLE(using Python-3.4)".

Try again. This step worked for me.

There are a number of font formats that one can set MIME types for, on both Apache and IIS servers. I've traditionally had luck with the following:

svg   as "image/svg+xml"                  (W3C: August 2011)
ttf   as "application/x-font-ttf"         (IANA: March 2013)
      or "application/x-font-truetype"
otf   as "application/x-font-opentype"    (IANA: March 2013)
woff  as "application/font-woff"          (IANA: January 2013)
woff2 as "application/font-woff2"         (W3C W./E.Draft: May 2014/March 2016)
eot   as "application/vnd.ms-fontobject"  (IANA: December 2005)
sfnt  as "application/font-sfnt"          (IANA: March 2013) 

According to the Internet Engineering Task Force who maintain the initial document regarding Multipurpose Internet Mail Extensions (MIME types) here: http://tools.ietf.org/html/rfc2045#section-5 ... it says in specifics:

"It is expected that additions to the larger set of supported types can generally be accomplished by the creation of new subtypes of these initial types. In the future, more top-level types may be defined only by a standards-track extension to this standard. If another top-level type is to be used for any reason, it must be given a name starting with "X-" to indicate its non-standard status and to avoid a potential conflict with a future official name."

As it were, and over time, additional MIME types get added as standards are created and accepted, therefor we see examples of vendor specific MIME types such as vnd.ms-fontobject and the like.

UPDATE August 16, 2013: WOFF was formally registered at IANA on January 3, 2013 and Webkit has been updated on March 5, 2013 and browsers that are sourcing this update in their latest versions will start issuing warnings about the server MIME types with the old x-font-woff declaration. Since the warnings are only annoying I would recommend switching to the approved MIME type right away. In an ideal world, the warnings will resolve themselves in time.

UPDATE February 26, 2015: WOFF2 is now in the W3C Editor's Draft with the proposed mime-type. It should likely be submitted to IANA in the next year (possibly by end of 2016) following more recent progress timelines. As well SFNT, the scalable/spline container font format used in the backbone table reference of Google Web Fonts with their sfntly java library and is already registered as a mime type with IANA and could be added to this list as well dependent on individual need.

UPDATE October 4, 2017: We can follow the progression of the WOFF2 format here with a majority of modern browsers supporting the format successfully. As well, we can follow the IETF's "font" Top-Level Media Type request for comments (RFC) tracker and document regarding the latest set of proposed font types for approval.

For those wishing to embed the typeface in the proper order in your CSS please visit this article. But again, I've had luck with the following order:

@font-face {
    font-family: 'my-web-font';
    src: url('webfont.eot');
    src: url('webfont.eot?#iefix') format('embedded-opentype'),
         url('webfont.woff2') format('woff2'),
         url('webfont.woff') format('woff'),
         url('webfont.ttf') format('truetype'),
         url('webfont.svg#webfont') format('svg');
    font-weight: normal;
    font-style: normal;
}

For Subversion auto-properties, these can be listed as:

# Font formats
svg   = svn:mime-type=image/svg+xml
ttf   = svn:mime-type=application/x-font-ttf
otf   = svn:mime-type=application/x-font-opentype
woff  = svn:mime-type=application/font-woff
woff2 = svn:mime-type=application/font-woff2
eot   = svn:mime-type=application/vnd.ms-fontobject
sfnt  = svn:mime-type=application/font-sfnt

Use the PHP nl2br to get the newlines in a text string..

$text = "Manu is a good boy.(Enter)He can code well.

echo nl2br($text);

Result.

Manu is a good boy.

He can code well.

please try this below command :

sudo php artisan cache:clear

sudo php artisan view:clear

sudo php artisan config:cache

Use attribute binding syntax instead

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    [attr.data-sectionvalue]="section.value">{{ section.text }}</li>  
</ol>

or

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    attr.data-sectionvalue="{{section.value}}">{{ section.text }}</li>  
</ol>

• How to add conditional attribute in Angular 2?

You just have to reset the values you don't want to their defaults. No need to get into a mess by using !important.

#zoomTarget .slikezamenjanje img {
    max-height: auto;
    padding-right: 0px;
}

Hatting

I think the key datum you are missing is that CSS comes with default values. If you want to override a value, set it back to its default, which you can look up.

For example, all CSS height and width attributes default to auto.

You don't need to convert NumPy array to Mat because OpenCV cv2 module can accept NumPyarray. The only thing you need to care for is that {0,1} is mapped to {0,255} and any value bigger than 1 in NumPy array is equal to 255. So you should divide by 255 in your code, as shown below.

img = numpy.zeros([5,5,3])

img[:,:,0] = numpy.ones([5,5])*64/255.0
img[:,:,1] = numpy.ones([5,5])*128/255.0
img[:,:,2] = numpy.ones([5,5])*192/255.0

cv2.imwrite('color_img.jpg', img)
cv2.imshow("image", img)
cv2.waitKey()

Seems like a bad way to do it (creating two correlated lists) but I'm assuming you have your reasons.

I'd parse the JSON string (which has a typo in your example, it's missing a comma between the two objects) into a strongly-typed object and then use a couple of LINQ queries to get the two lists.

void Main()
{
    string json = "{\"People\":[{\"FirstName\":\"Hans\",\"LastName\":\"Olo\"},{\"FirstName\":\"Jimmy\",\"LastName\":\"Crackedcorn\"}]}";

    var result = JsonConvert.DeserializeObject<RootObject>(json);

    var firstNames = result.People.Select (p => p.FirstName).ToList();
    var lastNames = result.People.Select (p => p.LastName).ToList();
}

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

public class RootObject
{
    public List<Person> People { get; set; }
}

This happens if you forgot to change your build settings to Simulator. Unless you want to build to a device, in which case you should see the other answers.

Here is a solution using Guava

private User findUserByName(List<User> userList, final String name) {
    Optional<User> userOptional =
            FluentIterable.from(userList).firstMatch(new Predicate<User>() {
                @Override
                public boolean apply(@Nullable User input) {
                    return input.getName().equals(name);
                }
            });
    return userOptional.isPresent() ? userOptional.get() : null; // return user if found otherwise return null if user name don't exist in user list
}

NGINX itself may not be the root cause.

IF "minimum ports per VM instance" set on the NAT Gateway -- which stand between your NGINX instance & the proxy_pass destination -- is too small for the number of concurrent requests, it has to be increased.

Solution: Increase the available number of ports per VM on NAT Gateway.

Context In my case, on Google Cloud, a reverse proxy NGINX was placed inside a subnet, with a NAT Gateway. The NGINX instance was redirecting requests to a domain associated with our backend API (upstream) through the NAT Gateway.

This documentation from GCP will help you understand how NAT is relevant to the NGINX 504 timeout.

ALTER TABLE Employee ADD DEFAULT 'SANDNES' FOR CityBorn

  File "C:\pythonwork\readthefile080410.py", line 120, in medications_minimum3
    counter[row[11]]+=1
TypeError: unhashable type: 'list'

row[11] is unhashable. It's a list. That is precisely (and only) what the error message means. You might not like it, but that is the error message.

Do this

counter[tuple(row[11])]+=1

Also, simplify.

d= [ row for row in c if counter[tuple(row[11])]>=sample_cutoff ]

I had the same need for conditional tests, and I figured out a good workaround. I defined a macro TEST_C that works like a TEST_F macro, but it has a third parameter, which is a boolean expression, evaluated runtime in main.cpp BEFORE the tests are started. Tests that evaluate false are not executed. The macro is ugly, but it look like:

#pragma once
extern std::map<std::string, std::function<bool()> >* m_conditionalTests;
#define TEST_C(test_fixture, test_name, test_condition)\
class test_fixture##_##test_name##_ConditionClass\
{\
    public:\
    test_fixture##_##test_name##_ConditionClass()\
    {\
        std::string name = std::string(#test_fixture) + "." + std::string(#test_name);\
        if (m_conditionalTests==NULL) {\
            m_conditionalTests = new std::map<std::string, std::function<bool()> >();\
        }\
        m_conditionalTests->insert(std::make_pair(name, []()\
        {\
            DeviceInfo device = Connection::Instance()->GetDeviceInfo();\
            return test_condition;\
        }));\
    }\
} test_fixture##_##test_name##_ConditionInstance;\
TEST_F(test_fixture, test_name)

Additionally, in your main.cpp, you need this loop to exclude the tests that evaluate false:

// identify tests that cannot run on this device
std::string excludeTests;
for (const auto& exclusion : *m_conditionalTests)
{
    bool run = exclusion.second();
    if (!run)
    {
        excludeTests += ":" + exclusion.first;
    }
}

// add the exclusion list to gtest
std::string str = ::testing::GTEST_FLAG(filter);
::testing::GTEST_FLAG(filter) = str + ":-" + excludeTests;

// run all tests
int result = RUN_ALL_TESTS();

Oh my God! It is not that much complicated, with these answers which also works. However, other answers tho this question also works well.

If you really want to use the vue-cli-service and if you want to have the port setting in your package.json file, which your 'vue create <app-name>' command basically creates, you can use the following configuration: --port 3000. So the whole configuration of your script would be like this:

...
"scripts": {
"serve": "vue-cli-service serve --port 3000",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint"
},
...

I am using @vue/cli 4.3.1 (vue --version) on a macOS device.

I have also added the vue-cli-service reference: https://cli.vuejs.org/guide/cli-service.html

• socket.isConnected() returns always true once the client connects (and even after the disconnect) weird !!
• socket.getInputStream().read()
  • makes the thread wait for input as long as the client is connected and therefore makes your program not do anything - except if you get some input
  • returns -1 if the client disconnected
• socket.getInetAddress().isReachable(int timeout): From isReachable(int timeout)

  Test whether that address is reachable. Best effort is made by the implementation to try to reach the host, but firewalls and server configuration may block requests resulting in a unreachable status while some specific ports may be accessible. A typical implementation will use ICMP ECHO REQUESTs if the privilege can be obtained, otherwise it will try to establish a TCP connection on port 7 (Echo) of the destination host.

Never is a good practice to pass the password argument directly from the command line, it is saved in the ~/.bash_history file and can be accessible from other applications.

Use this instead:

mysql -u user --host host --port 9999 database_name < /scripts/script.sql -p
Enter password:

Alternatively, you could set the .AcceptButton property of your form. Enter will automcatically create a click event.

Using a foreach loop demonstrates to anyone using your code that you are planning to do something to each member of a collection irrespective of its place in the collection. It also shows you aren't modifying the original collection (and throws an exception if you try to).

The other advantage of foreach is that it works on any IEnumerable, where as for only makes sense for IList, where each element actually has an index.

However, if you need to use the index of an element, then of course you should be allowed to use a for loop. But if you don't need to use an index, having one is just cluttering your code.

There are no significant performance implications as far as I'm aware. At some stage in the future it might be easier to adapt code using foreach to run on multiple cores, but that's not something to worry about right now.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace GetNameOfFiles
{
    public class Program
    {
        static void Main(string[] args)
        {
           string[] fileArray = Directory.GetFiles(@"YOUR PATH");
           for (int i = 0; i < fileArray.Length; i++)
           {

               Console.WriteLine(fileArray[i]);
           }
            Console.ReadLine();
        }
    }
}

Updated with swift 4

override func viewDidLoad() {
    super.viewDidLoad()
        self.navigationController?.navigationBar.tintColor = UIColor.blue
        self.navigationController?.navigationBar.barStyle = UIBarStyle.black
}

I was in your shoes for a while and finally ended up using node.js, because it can do hybrid solutions like having web and socket server in one. So php backend can submit requests thru http to node web server and then broadcast it with websocket. Very efficiant way to go.

I solved this problem by using custom Navigation layout

Using it you can customize anything in title on action bar:

build.gradle

dependencies {
    compile 'com.android.support:appcompat-v7:21.0.+'
    ...
}

AndroidManifest.xml

<application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name">
        <activity
            android:name=".MainActivity"
            android:theme="@style/ThemeName">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
</application>

styles.xml

<style name="ThemeName" parent="Theme.AppCompat.Light">
   <item name="actionBarStyle">@style/ActionBar</item>
   <item name="android:actionBarStyle" tools:ignore="NewApi">@style/ActionBar</item>

<style name="ActionBar" parent="Widget.AppCompat.ActionBar">
   <item name="displayOptions">showCustom</item>
   <item name="android:displayOptions" tools:ignore="NewApi">showCustom</item>

    <item name="customNavigationLayout">@layout/action_bar</item>
   <item name="android:customNavigationLayout" tools:ignore="NewApi">@layout/action_bar</item>

    <item name="background">@color/android:white</item>
   <item name="android:background">@color/android:white</item>

action_bar.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/action_bar_title"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:gravity="center_vertical"
          android:drawableLeft="@drawable/ic_launcher"
          android:drawablePadding="10dp"
          android:textSize="20sp"
          android:textColor="@android:color/black"
          android:text="@string/app_name"/>

Here's my USA-only solution, with the area code as an optional component, required delimiter for the extension, and regex comments:

function formatPhoneNumber($s) {
$rx = "/
    (1)?\D*     # optional country code
    (\d{3})?\D* # optional area code
    (\d{3})\D*  # first three
    (\d{4})     # last four
    (?:\D+|$)   # extension delimiter or EOL
    (\d*)       # optional extension
/x";
preg_match($rx, $s, $matches);
if(!isset($matches[0])) return false;

$country = $matches[1];
$area = $matches[2];
$three = $matches[3];
$four = $matches[4];
$ext = $matches[5];

$out = "$three-$four";
if(!empty($area)) $out = "$area-$out";
if(!empty($country)) $out = "+$country-$out";
if(!empty($ext)) $out .= "x$ext";

// check that no digits were truncated
// if (preg_replace('/\D/', '', $s) != preg_replace('/\D/', '', $out)) return false;
return $out;
}

And here's the script to test it:

$numbers = [
'3334444',
'2223334444',
'12223334444',
'12223334444x5555',
'333-4444',
'(222)333-4444',
'+1 222-333-4444',
'1-222-333-4444ext555',
'cell: (222) 333-4444',
'(222) 333-4444 (cell)',
];

foreach($numbers as $number) {
    print(formatPhoneNumber($number)."<br>\r\n");
}
