First of all you should know which statements are affected by the automatic semicolon insertion (also known as ASI for brevity):

• empty statement
• var statement
• expression statement
• do-while statement
• continue statement
• break statement
• return statement
• throw statement

The concrete rules of ASI, are described in the specification §11.9.1 Rules of Automatic Semicolon Insertion

Three cases are described:

1. When an offending token is encountered that is not allowed by the grammar, a semicolon is inserted before it if:

• The token is separated from the previous token by at least one LineTerminator.
• The token is }

e.g.:

    { 1
    2 } 3

is transformed to

    { 1
    ;2 ;} 3;

The NumericLiteral 1 meets the first condition, the following token is a line terminator.
The 2 meets the second condition, the following token is }.

2. When the end of the input stream of tokens is encountered and the parser is unable to parse the input token stream as a single complete Program, then a semicolon is automatically inserted at the end of the input stream.

e.g.:

    a = b
    ++c

is transformed to:

    a = b;
    ++c;

3. This case occurs when a token is allowed by some production of the grammar, but the production is a restricted production, a semicolon is automatically inserted before the restricted token.

Restricted productions:

    UpdateExpression :
        LeftHandSideExpression [no LineTerminator here] ++
        LeftHandSideExpression [no LineTerminator here] --
    
    ContinueStatement :
        continue ;
        continue [no LineTerminator here] LabelIdentifier ;
    
    BreakStatement :
        break ;
        break [no LineTerminator here] LabelIdentifier ;
    
    ReturnStatement :
        return ;
        return [no LineTerminator here] Expression ;
    
    ThrowStatement :
        throw [no LineTerminator here] Expression ; 

    ArrowFunction :
        ArrowParameters [no LineTerminator here] => ConciseBody

    YieldExpression :
        yield [no LineTerminator here] * AssignmentExpression
        yield [no LineTerminator here] AssignmentExpression

The classic example, with the ReturnStatement:

    return 
      "something";

is transformed to

    return;
      "something";

You didn't do what you're being asked to do.

What is asked:

I have to execute ../gradlew build

What you do

cd ..
gradlew build

That's not the same thing.

The first one will use the gradlew command found in the .. directory (mdeinum...), and look for the build file to execute in the current directory, which is (for example) chapter1-bookstore.

The second one will execute the gradlew command found in the current directory (mdeinum...), and look for the build file to execute in the current directory, which is mdeinum....

So the build file executed is not the same.

the field=value syntax in queries is a shorthand for field__exact=value. That is to say that Django puts query operators on query fields in the identifiers. Django supports the following operators:

exact
iexact
contains
icontains
in
gt
gte
lt
lte
startswith
istartswith
endswith
iendswith
range

date
year
iso_year
month
day
week
week_day
iso_week_day
quarter
time
hour
minute
second

isnull
regex
iregex

I'm sure by combining these with the Q objects as Dave Vogt suggests and using filter() or exclude() as Jason Baker suggests you'll get exactly what you need for just about any possible query.

I had to solve a similar problem--I wanted certain styles to only apply to mobile devices in landscape mode. Essentially the fonts and line spacing looked fine in every other context, so I just needed the one exception for mobile landscape. This media query worked perfectly:

@media all and (max-width: 600px) and (orientation:landscape) 
{
    /* styles here */
}

I was wondering if it will posible as long as the parent path in the page is same, only something new is appended to it.

So like let's say the user is at the page: http://domain.com/site/page.html Then the browser can let me do location.append = new.html and the page becomes: http://domain.com/site/page.htmlnew.html and the browser does not change it.

Or just allow the person to change get parameter, so let's location.get = me=1&page=1.

So original page becomes http://domain.com/site/page.html?me=1&page=1 and it does not refresh.

The problem with # is that the data is not cached (at least I don't think so) when hash is changed. So it is like each time a new page is being loaded, whereas back- and forward buttons in a non-Ajax page are able to cache data and do not spend time on re-loading the data.

From what I saw, the Yahoo history thing already loads all of the data at once. It does not seem to be doing any Ajax requests. So when a div is used to handle different method overtime, that data is not stored for each history state.

Try this:

    public static void main(String[] args)
    {
        Pattern p = Pattern.compile("^\\d+$");
        Scanner kb = new Scanner(System.in);
        int num1;
        int num2 = 0;
        String temp;
        Matcher numberMatcher;
        System.out.print("Enter number 1: ");
        try
        {
            num1 = kb.nextInt();
        }

        catch (java.util.InputMismatchException e)
        {
            System.out.println("Invalid Input");
            //
            return;
        }
        while(num2<num1)
        {
            System.out.print("Enter number 2: ");
            temp = kb.next();
            numberMatcher = p.matcher(temp);
            if (numberMatcher.matches())
            {
                num2 = Integer.parseInt(temp);
            }

            else
            {
                System.out.println("Invalid Number");
            }
        }
    }

You could try to parse the string into an int as well, but usually people try to avoid throwing exceptions.

What I have done is that I have defined a regular expression that defines a number, \d means a numeric digit. The + sign means that there has to be one or more numeric digits. The extra \ in front of the \d is because in java, the \ is a special character, so it has to be escaped.

public class Test{

Test2 test = new Test2();
JFrame frame = new JFrame();

Test(){
...
frame.setLayout(new BorderLayout());
frame.add(test, BorderLayout.CENTER);
...
}

//main
...
}

//public class Test2{
public class Test2 extends JPanel {

//JPanel test2 = new JPanel();

Test2(){
...
}

There is an underlying buffer/stream that getchar() and friends read from. When you enter text, the text is stored in a buffer somewhere. getchar() can stream through it one character at a time. Each read returns the next character until it reaches the end of the buffer. The reason it's not asking you for subsequent characters is that it can fetch the next one from the buffer.

If you run your script and type directly into it, it will continue to prompt you for input until you press CTRL+D (end of file). If you call it like ./program < myInput where myInput is a text file with some data, it will get the EOF when it reaches the end of the input. EOF isn't a character that exists in the stream, but a sentinel value to indicate when the end of the input has been reached.

As an extra warning, I believe getchar() will also return EOF if it encounters an error, so you'll want to check ferror(). Example below (not tested, but you get the idea).

main() {
    int c;
    do {
        c = getchar();
        if (c == EOF && ferror()) {
            perror("getchar");
        }
        else {
            putchar(c);
        }
    }
    while(c != EOF);
}

You can specify the whole day by doing a range, like so:

WHERE bk_date >= TO_DATE('2012-03-18', 'YYYY-MM-DD')
AND bk_date <  TO_DATE('2012-03-19', 'YYYY-MM-DD')

More simply you can use TRUNC:

WHERE TRUNC(bk_date) = TO_DATE('2012-03-18', 'YYYY-MM-DD')

TRUNC without parameter removes hours, minutes and seconds from a DATE.

Shorter version:

$('#multiselect1').multiselect({
    ...
    onChange: function() {
        console.log($('#multiselect1').val());
    }
}); 

Try to encapsulate the ajax call into a function and set the async option to false. Note that this option is deprecated since jQuery 1.8.

function foo() {
    var myajax = $.ajax({
        type: "POST",
        url: "CHService.asmx/SavePurpose",
        dataType: "text",
        data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
        contentType: "application/json; charset=utf-8",
        async: false, //add this
    });
    return myajax.responseText;
}

You can do this also:

$.ajax({
    type: "POST",
    url: "CHService.asmx/SavePurpose",
    dataType: "text",
    data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
    contentType: "application/json; charset=utf-8",
    async: false, //add this
}).done(function ( data ) {
        Success = true;
}).fail(function ( data ) {
       Success = false;
});

Python sequence slice addresses can be written as a[start:end:step] and any of start, stop or end can be dropped. a[::3] is every third element of the sequence.

I think of this as a two-step process:

1. subset the original data frame according to the filter supplied (Believe==FALSE); then

2. get the row count of this subset

For the first step, the subset function is a good way to do this (just an alternative to ordinary index or bracket notation).

For the second step, i would use dim or nrow

One advantage of using subset: you don't have to parse the result it returns to get the result you need--just call nrow on it directly.

so in your case:

v = nrow(subset(Santa, Believe==FALSE))     # 'subset' returns a data.frame

or wrapped in an anonymous function:

>> fnx = function(fac, lev){nrow(subset(Santa, fac==lev))}

>> fnx(Believe, TRUE)
      3

Aside from nrow, dim will also do the job. This function returns the dimensions of a data frame (rows, cols) so you just need to supply the appropriate index to access the number of rows:

v = dim(subset(Santa, Believe==FALSE))[1] 

An answer to the OP posted before this one shows the use of a contingency table. I don't like that approach for the general problem as recited in the OP. Here's the reason. Granted, the general problem of how many rows in this data frame have value x in column C? can be answered using a contingency table as well as using a "filtering" scheme (as in my answer here). If you want row counts for all values for a given factor variable (column) then a contingency table (via calling table and passing in the column(s) of interest) is the most sensible solution; however, the OP asks for the count of a particular value in a factor variable, not counts across all values. Aside from the performance hit (might be big, might be trivial, just depends on the size of the data frame and the processing pipeline context in which this function resides). And of course once the result from the call to table is returned, you still have to parse from that result just the count that you want.

So that's why, to me, this is a filtering rather than a cross-tab problem.

This happens every time you insert/ update and you don't use single quotes. When the variable is empty it will result in that error. Fix it by using ''

Assuming the first parameter is an empty variable here is a simple example:

Wrong

nvl( ,0)

Fix

nvl('' ,0)

Put your query into your database software and check it for that error. Generally this is an easy fix

In a university project I toyed around with yFiles by yWorks and found it had pretty good API.

Today I got this error, and I just did a small workaround which was too simple.

1. Close all of your chrome instances, that you might have opened before you opened Visual Studio.
2. Now stop debugging and run your application again.

You will not get the error again and if the debugger doesn't hit, refresh the browser again.

Update (12-Dec-2018):

I just tested this bug in Visual Studio 2019 preview, it seems like the bug is fixed now.

Hope this helps.

That is because of server SQL Mode - NO_ZERO_DATE.

From the reference: NO_ZERO_DATE - In strict mode, don't allow '0000-00-00' as a valid date. You can still insert zero dates with the IGNORE option. When not in strict mode, the date is accepted but a warning is generated.

A swift category that's mutating:

extension String {
    mutating func removeCharsFromEnd(removeCount:Int)
    {
        let stringLength = count(self)
        let substringIndex = max(0, stringLength - removeCount)
        self = self.substringToIndex(advance(self.startIndex, substringIndex))
    }
}

Use:

var myString = "abcd"
myString.removeCharsFromEnd(2)
println(myString) // "ab"

I think it's a good idea to keep avoiding modules unless you stick them into separate namespaces. Because in Intellisense methods in modules will be visible from everywhere in that namespace.

So instead of ModuleName.MyMethod() you end up with MyMethod() popups in anywhere and this kind of invalidates the encapsulation. (at least in the programming level).

That's why I always try to create Class with shared methods, seems so much better.

try

raw_input('Enter your input:')  # If you use Python 2
input('Enter your input:')      # If you use Python 3

and if you want to have a numeric value just convert it:

try:
    mode=int(raw_input('Input:'))
except ValueError:
    print "Not a number"

input[readonly], input:read-only {
    /* styling info here */
}

Shoud cover all the cases for a readonly input field...

Lists of bytes are subscriptable (at least in Python 3.6). This way you can retrieve the decimal value of each byte individually.

>>> intlist = [64, 4, 26, 163, 255]
>>> bytelist = bytes(intlist)       # b'@x04\x1a\xa3\xff'

>>> for b in bytelist:
...    print(b)                     # 64  4  26  163  255

>>> [b for b in bytelist]           # [64, 4, 26, 163, 255]

>>> bytelist[2]                     # 26 

I got this error when one of my properties that was required for the constructor was not public. Make sure all the parameters in the constructor go to properties that are public if this is the case:

using statements namespace someNamespace

public class ExampleClass {

  //Properties - one is not visible to the class calling the constructor
  public string Property1 { get; set; }
  string Property2 { get; set; }

   //Constructor
   public ExampleClass(string property1, string property2)
  {
     this.Property1 = property1;
     this.Property2 = property2;  //this caused that error for me
  }
}

The accepted answer is good, but has two limitations.
It drops empty lines and lines beginning with ;

To read lines of any content, you need the delayed expansion toggling technic.

@echo off
SETLOCAL DisableDelayedExpansion
FOR /F "usebackq delims=" %%a in (`"findstr /n ^^ text.txt"`) do (
    set "var=%%a"
    SETLOCAL EnableDelayedExpansion
    set "var=!var:*:=!"
    echo(!var!
    ENDLOCAL
)

Findstr is used to prefix each line with the line number and a colon, so empty lines aren't empty anymore.

DelayedExpansion needs to be disabled, when accessing the %%a parameter, else exclamation marks ! and carets ^ will be lost, as they have special meanings in that mode.

But to remove the line number from the line, the delayed expansion needs to be enabled.
set "var=!var:*:=!" removes all up to the first colon (using delims=: would remove also all colons at the beginning of a line, not only the one from findstr).
The endlocal disables the delayed expansion again for the next line.

The only limitation is now the line length limit of ~8191, but there seems no way to overcome this.

In the below example, I have stored the Makefile folder path to LOCAL_PKG_DIR and then use LOCAL_PKG_DIR variable in targets.

Makefile:

LOCAL_PKG_DIR := $(shell eval pwd)

.PHONY: print
print:
    @echo $(LOCAL_PKG_DIR)

Terminal output:

$ make print
/home/amrit/folder

You can simply do it with train_test_split() method available in Scikit learn:

from sklearn.model_selection import train_test_split 
train, test = train_test_split(X, test_size=0.25, stratify=X['YOUR_COLUMN_LABEL']) 

I have also prepared a short GitHub Gist which shows how stratify option works:

https://gist.github.com/SHi-ON/63839f3a3647051a180cb03af0f7d0d9

The title attribute also works well with other html elements, for example a link...

<a title="hover text" ng-href="{{getUrl()}}"> download link
</a>

In case if someone returns with the same question for Android platform, you cannot use the inbuilt remove() method if you are targeting for Android API-18 or less. The remove() method is added on API level 19. Thus, the best possible thing to do is to extend the JSONArray to create a compatible override for the remove() method.

public class MJSONArray extends JSONArray {

    @Override
    public Object remove(int index) {

        JSONArray output = new JSONArray();     
        int len = this.length(); 
        for (int i = 0; i < len; i++)   {
            if (i != index) {
                try {
                    output.put(this.get(i));
                } catch (JSONException e) {
                    throw new RuntimeException(e);
                }
            }
        } 
        return output;
        //return this; If you need the input array in case of a failed attempt to remove an item.
     }
}

EDIT As Daniel pointed out, handling an error silently is bad style. Code improved.

While dragging the TextBox it self Press F4 for Properties and under the Textmode set to Multiline, The representation of multiline to a text box is it can be sizable at 6 sides. And no need to include any newline characters for getting multiline. May be you set it multiline but you dint increased the size of the Textbox at design time.

Late joining this conversation to shed light on a mildly interesting factoid for web-facing, analytics-aware websites. Passing the mic over to Michael Papworth:

https://github.com/michaelpapworth/jQuery.navigate

"When using website analytics, window.location is not sufficient due to the referer not being passed on the request. The plugin resolves this and allows for both aliased and parametrised URLs."

If one examines the code what it does is this:

   var methods = {
            'goTo': function (url) {
                // instead of using window.location to navigate away
                // we use an ephimeral link to click on and thus ensure
                // the referer (current url) is always passed on to the request
                $('<a></a>').attr("href", url)[0].click();
            },
            ...
   };

Neato!

Before you can add files in an unversioned directory, you have to add the directory itself to the versioning:

svn add directory_name

will add the directory directory_name and all sub-directories: http://svnbook.red-bean.com/en/1.8/svn.ref.svn.c.add.html

JSON.parse("your string");

That's all.

You might also checkout http://www.concretejs.com which is a modern, lightweight, Html5 canvas framework that enables hit detection, layering, and lots of other peripheral things. You can do things like this:

var wrapper = new Concrete.Wrapper({
  width: 500,
  height: 300,
  container: el
});

var layer1 = new Concrete.Layer();
var layer2 = new Concrete.Layer();

wrapper.add(layer1).add(layer2);

// draw stuff
layer1.sceneCanvas.context.fillStyle = 'red';
layer1.sceneCanvas.context.fillRect(0, 0, 100, 100);

// reorder layers
layer1.moveUp();

// destroy a layer
layer1.destroy();

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

Yes, you can achieve it by find_elements_by_css_selector("*") or find_elements_by_xpath(".//*").

However, this doesn't sound like a valid use case to find all children of an element. It is an expensive operation to get all direct/indirect children. Please further explain what you are trying to do. There should be a better way.

from selenium import webdriver

driver = webdriver.Firefox()
driver.get("http://www.stackoverflow.com")

header = driver.find_element_by_id("header")

# start from your target element, here for example, "header"
all_children_by_css = header.find_elements_by_css_selector("*")
all_children_by_xpath = header.find_elements_by_xpath(".//*")

print 'len(all_children_by_css): ' + str(len(all_children_by_css))
print 'len(all_children_by_xpath): ' + str(len(all_children_by_xpath))

The built in Java URLEncoder is doing what it's supposed to, and you should use it.

A "+" or "%20" are both valid replacements for a space character in a URL. Either one will work.

A ":" should be encoded, as it's a separator character. i.e. http://foo or ftp://bar. The fact that a particular browser can handle it when it's not encoded doesn't make it correct. You should encode them.

As a matter of good practice, be sure to use the method that takes a character encoding parameter. UTF-8 is generally used there, but you should supply it explicitly.

URLEncoder.encode(yourUrl, "UTF-8");

For CodeIgniter 4, use the following:

<?php    
    echo \CodeIgniter\CodeIgniter::CI_VERSION;
?>

Set up a trap (you can trap several signals with one handler):

signal (SIGQUIT, my_handler);
signal (SIGINT, my_handler);

Handle the signal however you want, but be aware of limitations and gotchas:

void my_handler (int sig)
{
  /* Your code here. */
}

Chrome currently supports only a small subset of ActiveX components entirely on purpose, and it's never going to support them all, and especially lots of random 3rd party propriety ones.

Why?

Because ActiveX is a mess - it's a huge security hole and all the components can run at a higher security level than the browser.

That means that if you let in an ActiveX component it owns your PC - and while many are not malign most are resource hogs. Also if a malign site can't hack your browser it might still be able to hack one of its ActiveXs.

This is completely against Chrome's sandbox everything and wall off every tab approach - the reason why Chrome is by far the quickest, most secure and most stable browser is the same reason that it currently only supports Flash, Silverlight and one or two more.

However, it sounds like you're not really developing a web application anyway - your site in IE is basically a portal to downloading further ActiveX-based applications. Why worry about supporting anything that your DVR clients with their coding teams writing ActiveXs don't?

INSERT INTO `table` ( `data` , `date` ) VALUES('".$data."',NOW()+INTERVAL 1 DAY);

You can use boost graph library and cyclic dependencies. It has the solution for finding cycles with back_edge function.

dialog-component.css

This code works perfectly for me, other solutions don't work. Use the ::ng-deep shadow-piercing descendant combinator to force a style down through the child component tree into all the child component views. The ::ng-deep combinator works to any depth of nested components, and it applies to both the view children and content children of the component.

 ::ng-deep .mat-dialog-container {
    height: 400px !important;
    width: 400px !important;
}

theharshest's answer is the best solution, but FYI the problem you were encountering has to do with the fact that a Tag object in Beautiful Soup acts like a Python dictionary. If you access tag['name'] on a tag that doesn't have a 'name' attribute, you'll get a KeyError.

Here's a really simple example that might get you started:

$(document).ready(function() {
    var $dragging = null;

    $(document.body).on("mousemove", function(e) {
        if ($dragging) {
            $dragging.offset({
                top: e.pageY,
                left: e.pageX
            });
        }
    });


    $(document.body).on("mousedown", "div", function (e) {
        $dragging = $(e.target);
    });

    $(document.body).on("mouseup", function (e) {
        $dragging = null;
    });
});

Example: http://jsfiddle.net/Jge9z/

I understand that I shall use the mouse position relative to the container div (in which the div shall be dragged) and that I shall set the divs offset relative to those values.

Not so sure about that. It seems to me that in drag and drop you'd always want to use the offset of the elements relative to the document.

If you mean you want to constrain the dragging to a particular area, that's a more complicated issue (but still doable).

Note:

Function was written to handle seeding of randomized set creation. You should not rely on set splitting that doesn't randomize the sets.

import numpy as np
import pandas as pd

def train_validate_test_split(df, train_percent=.6, validate_percent=.2, seed=None):
    np.random.seed(seed)
    perm = np.random.permutation(df.index)
    m = len(df.index)
    train_end = int(train_percent * m)
    validate_end = int(validate_percent * m) + train_end
    train = df.iloc[perm[:train_end]]
    validate = df.iloc[perm[train_end:validate_end]]
    test = df.iloc[perm[validate_end:]]
    return train, validate, test

Demonstration

I'm using this to set up boost from cmake in my CMakeLists.txt. Try something similar (make sure to update paths to your installation of boost).

SET (BOOST_ROOT "/opt/boost/boost_1_57_0")
SET (BOOST_INCLUDEDIR "/opt/boost/boost-1.57.0/include")
SET (BOOST_LIBRARYDIR "/opt/boost/boost-1.57.0/lib")

SET (BOOST_MIN_VERSION "1.55.0")
set (Boost_NO_BOOST_CMAKE ON)
FIND_PACKAGE(Boost ${BOOST_MIN_VERSION} REQUIRED)
if (NOT Boost_FOUND)
  message(FATAL_ERROR "Fatal error: Boost (version >= 1.55) required.")
else()
  message(STATUS "Setting up BOOST")
  message(STATUS " Includes - ${Boost_INCLUDE_DIRS}")
  message(STATUS " Library  - ${Boost_LIBRARY_DIRS}")
  include_directories(${Boost_INCLUDE_DIRS})
  link_directories(${Boost_LIBRARY_DIRS})
endif (NOT Boost_FOUND)

This will either search default paths (/usr, /usr/local) or the path provided through the cmake variables (BOOST_ROOT, BOOST_INCLUDEDIR, BOOST_LIBRARYDIR). It works for me on cmake > 2.6.

You can use System.Reflection.Assembly.Load*() methods and then grab their AssemblyInfo.

The QueryString collection is used to retrieve the variable values in the HTTP query string.

The HTTP query string is specified by the values following the question mark (?), like this:

Link with a query string

The line above generates a variable named txt with the value "this is a query string test".

Query strings are also generated by form submission, or by a user typing a query into the address bar of the browser.

And see this sample : http://www.codeproject.com/Articles/5876/Passing-variables-between-pages-using-QueryString

refer this : http://www.dotnetperls.com/querystring

Just in keeping the parent value in child attribute

var Foo = function(){
    this.val= 4;
    this.test={};
    this.test.val=6;
    this.test.par=this;
}

var myObj = new Foo();
alert(myObj.val);
alert(myObj.test.val);
alert(myObj.test.par.val);

mutable does exist as you infer to allow one to modify data in an otherwise constant function.

The intent is that you might have a function that "does nothing" to the internal state of the object, and so you mark the function const, but you might really need to modify some of the objects state in ways that don't affect its correct functionality.

The keyword may act as a hint to the compiler -- a theoretical compiler could place a constant object (such as a global) in memory that was marked read-only. The presence of mutable hints that this should not be done.

Here are some valid reasons to declare and use mutable data:

• Thread safety. Declaring a mutable boost::mutex is perfectly reasonable.
• Statistics. Counting the number of calls to a function, given some or all of its arguments.
• Memoization. Computing some expensive answer, and then storing it for future reference rather than recomputing it again.

Example

So, if we had a child element with an id of "child-element" and we wanted to get it's left/top position relative to a parent element, say a div that had a class of "item-parent", we'd use this code.

var position = $("#child-element").offsetRelative("div.item-parent");
alert('left: '+position.left+', top: '+position.top);

Plugin Finally, for the actual plugin (with a few notes expalaining what's going on):

// offsetRelative (or, if you prefer, positionRelative)
(function($){
    $.fn.offsetRelative = function(top){
        var $this = $(this);
        var $parent = $this.offsetParent();
        var offset = $this.position();
        if(!top) return offset; // Didn't pass a 'top' element 
        else if($parent.get(0).tagName == "BODY") return offset; // Reached top of document
        else if($(top,$parent).length) return offset; // Parent element contains the 'top' element we want the offset to be relative to 
        else if($parent[0] == $(top)[0]) return offset; // Reached the 'top' element we want the offset to be relative to 
        else { // Get parent's relative offset
            var parent_offset = $parent.offsetRelative(top);
            offset.top += parent_offset.top;
            offset.left += parent_offset.left;
            return offset;
        }
    };
    $.fn.positionRelative = function(top){
        return $(this).offsetRelative(top);
    };
}(jQuery));

Note : You can Use this on mouseClick or mouseover Event

$(this).offsetRelative("div.item-parent");

if you have only two "kinds" of column styles - use one as TD and one as TH. Then, declare a class for the table and a sub-class for that table's THs and TDs. Then your HTML can be super efficient.

You could use pandas plot as @Bharath suggest:

import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)

Output:

Updated:

from matplotlib.colors import ListedColormap df.set_index('App')\ .reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\ .T.plot(kind='bar', stacked=True, colormap=ListedColormap(sns.color_palette("GnBu", 10)), figsize=(12,6))

Updated Pandas 0.21.0+ reindex_axis is deprecated, use reindex

from matplotlib.colors import ListedColormap

df.set_index('App')\
  .reindex(df.set_index('App').sum().sort_values().index, axis=1)\
  .T.plot(kind='bar', stacked=True,
          colormap=ListedColormap(sns.color_palette("GnBu", 10)), 
          figsize=(12,6))

Output:

For development purpose https://mailtrap.io/ provides you with all the settings that needs to be added in .env file. Eg:

Host:   mailtrap.io
Port:   25 or 465 or 2525
Username:   cb1d1475bc6cce
Password:   7a330479c15f99
Auth:   PLAIN, LOGIN and CRAM-MD5
TLS:    Optional

Otherwise for implementation purpose you can get the smtp credentials to be added in .env file from the mail (like gmail n all)

After addition make sure to restart the server

Sometime it is fixed by the Padding .. if you can play with that, then, it should fix your problem

<style type=text/css>

YourbuttonByID {Padding: 20px 80px; "for example" padding-left:50px; 
 padding-right:30px "to fix the text in the middle 
 without interfering with the text itself"}

</style>

It worked for me

For simple cases, I would also suggest looking at XmlOutput a fluent interface for building Xml.

XmlOutput is great for simple Xml creation with readable and maintainable code, while generating valid Xml. The orginal post has some great examples.

As some sugested you can use apache or jax-ws. You can also use tools that generate code from WSDL such as ws-import but in my opinion the best way to consume web service is to create a dynamic client and invoke only operations you want not everything from wsdl. You can do this by creating a dynamic client: Sample code:

String endpointUrl = ...;

QName serviceName = new QName("http://com/ibm/was/wssample/echo/",
 "EchoService");
QName portName = new QName("http://com/ibm/was/wssample/echo/",
 "EchoServicePort");

/** Create a service and add at least one port to it. **/ 
Service service = Service.create(serviceName);
service.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING, endpointUrl);

/** Create a Dispatch instance from a service.**/ 
Dispatch<SOAPMessage> dispatch = service.createDispatch(portName, 
SOAPMessage.class, Service.Mode.MESSAGE);

/** Create SOAPMessage request. **/
// compose a request message
MessageFactory mf = MessageFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL);

// Create a message.  This example works with the SOAPPART.
SOAPMessage request = mf.createMessage();
SOAPPart part = request.getSOAPPart();

// Obtain the SOAPEnvelope and header and body elements.
SOAPEnvelope env = part.getEnvelope();
SOAPHeader header = env.getHeader();
SOAPBody body = env.getBody();

// Construct the message payload.
SOAPElement operation = body.addChildElement("invoke", "ns1",
 "http://com/ibm/was/wssample/echo/");
SOAPElement value = operation.addChildElement("arg0");
value.addTextNode("ping");
request.saveChanges();

/** Invoke the service endpoint. **/
SOAPMessage response = dispatch.invoke(request);

/** Process the response. **/

I think you are on the right track with COALESCE. See here for an example of building a comma-delimited string:

http://www.sqlteam.com/article/using-coalesce-to-build-comma-delimited-string

In your ASPX page you've got the list like this:

    <asp:CheckBoxList ID="YrChkBox" runat="server" 
        onselectedindexchanged="YrChkBox_SelectedIndexChanged"></asp:CheckBoxList>
    <asp:Button ID="button" runat="server" Text="Submit" />

In your code behind aspx.cs page, you have this:

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            // Populate the CheckBoxList items only when it's not a postback.
            YrChkBox.Items.Add(new ListItem("Item 1", "Item1"));
            YrChkBox.Items.Add(new ListItem("Item 2", "Item2"));
        }
    }

    protected void YrChkBox_SelectedIndexChanged(object sender, EventArgs e)
    {
        // Create the list to store.
        List<String> YrStrList = new List<string>();
        // Loop through each item.
        foreach (ListItem item in YrChkBox.Items)
        {
            if (item.Selected)
            {
                // If the item is selected, add the value to the list.
                YrStrList.Add(item.Value);
            }
            else
            {
                // Item is not selected, do something else.
            }
        }
        // Join the string together using the ; delimiter.
        String YrStr = String.Join(";", YrStrList.ToArray());

        // Write to the page the value.
        Response.Write(String.Concat("Selected Items: ", YrStr));
    }

Ensure you use the if (!IsPostBack) { } condition because if you load it every page refresh, it's actually destroying the data.

You are specifying .fixedbutton in your CSS (a class) and specifying the id on the element itself.

Change your CSS to the following, which will select the id fixedbutton

#fixedbutton {
    position: fixed;
    bottom: 0px;
    right: 0px; 
}

short way

$scheme = $_SERVER['REQUEST_SCHEME'] . '://';

The last update for "windows git" did move the git.exe file from the /bin folder to the /cmd folder. So, to use git with IDEs such as webStorm or Android Studio you can use the path :

C:\Users\<user>\AppData\Local\GitHub\PortableGit_<..numbers..>\cmd\git.exe

But if you want to have linux-like commands such as git, ssh, ls, cp under windows powerShell or cmd add to your windows PATH variables :

C:\Users\<user>\AppData\Local\GitHub\PortableGit_<...numbers...>\usr\bin

change <user> and <...numbers...> to your values and reboot!

Also, you will have to update this everytime git updates since it might change the portable folder name. If folder structure changes I will update this post.

Thx @dennisschagt for the comment above! ;)

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

If you are using RC5 then import this:

import { CommonModule } from '@angular/common';  
import { BrowserModule } from '@angular/platform-browser';

and be sure to import CommonModule from the module that is providing your component.

 @NgModule({
    imports: [CommonModule],
    declarations: [MyComponent]
  ...
})
class MyComponentModule {}

This can occur on android too not just computers. Was browsing using Kiwi when the site I was on began to endlessly redirect so I cut net access to close it out and noticed my phone had DL'd something f.txt in my downloaded files.

Deleted it and didn't open.

Exclamation mark makes any function always return a boolean.
The final value is the negation of the value returned by the function.

!function bool() { return false; }() // true
!function bool() { return true; }() // false

Omitting ! in the above examples would be a SyntaxError.

function bool() { return true; }() // SyntaxError

However, a better way to achieve this would be:

(function bool() { return true; })() // true

Use summarise in the dplyr package:

library(dplyr)
summarise(df, Average = mean(col_name, na.rm = T))

note: dplyr supports both summarise and summarize.

myobj.A

------- or ----------

myobj['A']

will get you 'B'

If I am not wrong, this should work:

    if not exists (Select 1 from tableName)
create table ...

Use ng-click in place of onclick. and its as simple as that:

<a href="www.mysite.com" ng-click="return theFunction();">Item</a>

<script type="text/javascript">
function theFunction () {
    // return true or false, depending on whether you want to allow 
    // the`href` property to follow through or not
 }
</script>

Although this is not a built in Unix solution, I've implemented a solution for this using a shell script that can be included in whatever shell script you are using. This is usable on POSIX compliant setups. (sh, bash, ksh, zsh) The full description is available in the github repo -> https://github.com/plyint/encpass.sh. This solution will auto-generate a key for your script and store the key and your password (or other secrets) in a hidden directory under your user (i.e. ~/.encpass).

In your script you just need to source encpass.sh and then call the get_secret method. For example:

#!/bin/sh
. encpass.sh
password=$(get_secret)

Pasted below is lite version of the code for encpass.sh(you can get the full version over on github) for easier visibility:

 # DESCRIPTION: 
 # This script allows a user to encrypt a password (or any other secret) at

 # inadvertently be sent to or discovered by an individual at a later date.
 #
 # This script generates an AES 256 bit symmetric key for each script (or user-
 # defined bucket) that stores secrets.  This key will then be used to encrypt 
 # all secrets for that script or bucket.  encpass.sh sets up a directory 
 # (.encpass) under the user's home directory where keys and secrets will be 
 # stored.

Here is a way to integrate with explorer. It will popup a extra menu item when you right-click in any folder within Windows Explorer:

Here are the steps:

1. Create this key: \HKEY_CLASSES_ROOT\Folder\shell\dosherewithadmin
2. Change its Default value to whatever you want to appear as the menu item text. Ex "DOS Shell as Admin"
3. Create this another key: \HKEY_CLASSES_ROOT\Folder\shell\dosherewithadmin\command
4. Change its default value to this, ipsis litteris: powershell.exe -Command "Start-Process -Verb RunAs 'cmd.exe' -Args '/k pushd "%1"'"
5. It's done. Now right-click in any folder and you will see your item there within the other items.

*Use pushd instead of cd to allow it to work in any drive. :-)

Add an extra apostrophe ' to the MessageFormat pattern String to ensure the ' character is displayed

String text = 
     java.text.MessageFormat.format("You''re about to delete {0} rows.", 5);
                                         ^

An apostrophe (aka single quote) in a MessageFormat pattern starts a quoted string and is not interpreted on its own. From the javadoc

A single quote itself must be represented by doubled single quotes '' throughout a String.

The String You\\'re is equivalent to adding a backslash character to the String so the only difference will be that You\re will be produced rather than Youre. (before double quote solution '' applied)

declare @sql varchar(100);

declare @tablename as varchar(100);

select @tablename = 'your_table_name';

create table #tmp 
    (col1 int, col2 int, col3 int);

set @sql = 'select aa, bb, cc from ' + @tablename;

insert into #tmp(col1, col2, col3) exec( @sql );

select * from #tmp;

In addressing your comment that you need your current time, and not the system time, you will have to make an adjustment yourself, there are 3600 seconds in an hour (the unit timestamps use), so use that. for example, if your system time was one hour behind:

$time = date('H:i',time() + 3600);

Update

Below you've said:

Sorry, i can't predict date format before, it should be like dd-mm-yyyy or dd/mm/yyyy or dd-mmm-yyyy format finally i wanted to convert all this format to dd-MMM-yyyy format.

That completely changes the question. It'll be much more complex if you can't control the format. There is nothing built into JavaScript that will let you specify a date format. Officially, the only date format supported by JavaScript is a simplified version of ISO-8601: yyyy-mm-dd, although in practice almost all browsers also support yyyy/mm/dd as well. But other than that, you have to write the code yourself or (and this makes much more sense) use a good library. I'd probably use a library like moment.js or DateJS (although DateJS hasn't been maintained in years).

Original answer:

If the format is always dd/mm/yyyy, then this is trivial:

var parts = str.split("/");
var dt = new Date(parseInt(parts[2], 10),
                  parseInt(parts[1], 10) - 1,
                  parseInt(parts[0], 10));

split splits a string on the given delimiter. Then we use parseInt to convert the strings into numbers, and we use the new Date constructor to build a Date from those parts: The third part will be the year, the second part the month, and the first part the day. Date uses zero-based month numbers, and so we have to subtract one from the month number.

G++ does support C++14 both via -std=c++14 and -std=c++1y. The latter was the common name for the standard before it was known in which year it would be released. In older versions (including yours) only the latter is accepted as the release year wasn't known yet when those versions were released.

I used "sudo apt-get install g++" which should automatically retrieve the latest version, is that correct?

It installs the latest version available in the Ubuntu repositories, not the latest version that exists.

The latest GCC version is 5.2.

you can change the file executable by using chmod like this

chmod 755 file.sh

and use this command for execute

./file.sh

You do not need to use an anonymous function with setTimeout. You can do something like this:

setTimeout(doSomething, 3000);

function doSomething() {
   //do whatever you want here
}

I personally feel casting is the prettiest.

$iSomeVar = (int) $sSomeOtherVar;

Should a string like 'Hello' be sent, it will be cast to integer 0. For a string such as '22 years old', it will be cast to integer 22. Anything it can't parse to a number becomes 0.

If you really do NEED the speed, I guess the other suggestions here are correct in assuming that coercion is the fastest.

<div class="post_category">
        <?php $category = get_the_category();
             $allcategory = get_the_category(); 
        foreach ($allcategory as $category) {
        ?>
           <a class="btn"><?php echo $category->cat_name;; ?></a>
        <?php 
        }
        ?>
 </div>

Today, you should be representing a folder using its content: URI as obtained from the Storage Access Framework, and opening it should be as simple as:

Intent i = new Intent(Intent.ACTION_VIEW, uri);
startActivity(i);

Alas, the Files app currently contains a bug that causes it to crash when you try this using the external storage provider. Folders from third party providers however can be displayed in this way.

Swift:

@connor is the right answer, but if you want to add lines in a print statement what you are looking for is \n and/or \r, these are called Escape Sequences or Escaped Characters, this is a link to Apple documentation on the topic..

Example:

print("First line\nSecond Line\rThirdLine...")

You can achieve this by using the following query:

EXEC sp_msforeachdb 
    'IF EXISTS
    (
        SELECT  1 
        FROM    [?].sys.objects 
        WHERE   name LIKE ''OBJECT_TO_SEARCH''
    )
    SELECT 
        ''?''       AS DB, 
        name        AS Name, 
        type_desc   AS Type 
    FROM [?].sys.objects 
    WHERE name LIKE ''OBJECT_TO_SEARCH'''

Just replace OBJECT_TO_SEARCH with the actual object name you are interested in (or part of it, surrounded with %).

More details here: https://peevsvilen.blog/2019/07/30/search-for-an-object-in-sql-server/

You can't use a LinearLayout for this, but you can use a FrameLayout. In a FrameLayout, the z-index is defined by the order in which the items are added, for example:

<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/my_drawable"
        android:scaleType="fitCenter"
        />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|center"
        android:padding="5dp"
        android:text="My Label"
        />
</FrameLayout>

In this instance, the TextView would be drawn on top of the ImageView, along the bottom center of the image.

The original question was how to tell if a variable was numeric, not if it "has a numeric value".

There are a few operators that have separate modes of operation for numeric and string operands, where "numeric" means anything that was originally a number or was ever used in a numeric context (e.g. in $x = "123"; 0+$x, before the addition, $x is a string, afterwards it is considered numeric).

One way to tell is this:

if ( length( do { no warnings "numeric"; $x & "" } ) ) {
    print "$x is numeric\n";
}

If the bitwise feature is enabled, that makes & only a numeric operator and adds a separate string &. operator, you must disable it:

if ( length( do { no if $] >= 5.022, "feature", "bitwise"; no warnings "numeric"; $x & "" } ) ) {
    print "$x is numeric\n";
}

(bitwise is available in perl 5.022 and above, and enabled by default if you use 5.028; or above.)

Trapping CHLD signal may not work because you can lose some signals if they arrived simultaneously.

#!/bin/bash

trap 'rm -f $tmpfile' EXIT

tmpfile=$(mktemp)

doCalculations() {
    echo start job $i...
    sleep $((RANDOM % 5)) 
    echo ...end job $i
    exit $((RANDOM % 10))
}

number_of_jobs=10

for i in $( seq 1 $number_of_jobs )
do
    ( trap "echo job$i : exit value : \$? >> $tmpfile" EXIT; doCalculations ) &
done

wait 

i=0
while read res; do
    echo "$res"
    let i++
done < "$tmpfile"

echo $i jobs done !!!

I fixed the same problem on Google Chrome with the following:

1. Choose Customize and control Google Chrome (the button in the top right corner).

2. Choose Settings.

3. Go to Extensions.

4. Unmark all the extensions there. (They should show as Enable instead of Enabled.)

you may try using trigger() Reference Link

$('#form_id').trigger("reset");

That's because Chrome added support for source maps.

Go to the developer tools (F12 in the browser), then select the three dots in the upper right corner, and go to Settings.

Then, look for Sources, and disable the options: "Enable javascript source maps" "Enable CSS source maps"

If you do that, that would get rid of the warnings. It has nothing to do with your code. Check the developer tools in other pages and you will see the same warning.

type sqlplus/"as sysdba" in cmd for connection in cmd prompt

Can a relational database input latitudes and longitudes of places and roads, and compute the shortest path between them - no. This is one problem that shows SQL is not Turing complete.

But C++ can do it, and can do any problem. Thus it is.

To reference an element by id, you need to use the # qualifier.

Try:

alert($("#link1").text());

To replace it, you could use:

$("#link1").text('New text');

The .html() function would work in this case too.

Just remove the throw from the catch block — change it to an echo or otherwise handle the error.

It's not telling you that objects can only be thrown in the catch block, it's telling you that only objects can be thrown, and the location of the error is in the catch block — there is a difference.

In the catch block you are trying to throw something you just caught — which in this context makes little sense anyway — and the thing you are trying to throw is a string.

A real-world analogy of what you are doing is catching a ball, then trying to throw just the manufacturer's logo somewhere else. You can only throw a whole object, not a property of the object.

From DateTimePicker:

First date:

DateTime first_date = new DateTime(DateTimePicker.Value.Year, DateTimePicker.Value.Month, 1);

Last date:

DateTime last_date = new DateTime(DateTimePicker.Value.Year, DateTimePicker.Value.Month, DateTime.DaysInMonth(DateTimePicker.Value.Year, DateTimePicker.Value.Month));

PHP uses weak typing (which it calls 'type juggling'), which is a bad idea (though that's a conversation for another time). When you try to use a variable in a context that requires a boolean, it will convert whatever your variable is into a boolean, according to some mostly arbitrary rules available here: http://www.php.net/manual/en/language.types.boolean.php#language.types.boolean.casting

Don't forget also that the path for the file is on the actual oracle server machine and not any local development machine that might be calling your stored procedure. This is probably very obvious but something that should be remembered.

Use this code:

QFile inputFile(fileName);
if (inputFile.open(QIODevice::ReadOnly))
{
   QTextStream in(&inputFile);
   while (!in.atEnd())
   {
      QString line = in.readLine();
      ...
   }
   inputFile.close();
}

The problem is the project is under source control and every time I pull the .xcodeproj is updated. And since my provisioning profile is different than the one in source control, the Unit Test target automatically switches to "Do not code sign". So I simply have to set the profile there after each git pull.

Apparently if deploying to a device, if there is a unit test target, it must be code signed.

Steps:

1) Change target to your test target (AppnameTests)

2) Make sure "Code Signing Identity" is NOT "Don't Code Sign". Pick a profile to sign with

That is all I had to change to get it to work.

If you use Windows 10 Home, all issues about Hyper-V is irrelevant for you as it is not supported (Pro is required) and you will not have conflicts :)

Remark: trying to update HAXM to latest version incidentally removed it, but then can't update with SDK manager, as it shows that latest version 6.1.1 is unsupported for Windows (seems configuration is broken, found 6.1.1 for Mac and 6.0.6 for Windows only inside) So would recommend manually download HAXM and install as described: copy to sdk_location/sdk/extras/intel/Hardware_Accelerated_Execution_Manager and run the silent_install.bat

You can Use the following function in you code directly,

    function artoxml($arr, $i=1,$flag=false){
    $sp = "";
    for($j=0;$j<=$i;$j++){
        $sp.=" ";
     }
    foreach($arr as $key=>$val){
        echo "$sp&lt;".$key."&gt;";
        if($i==1) echo "\n";
        if(is_array($val)){
            if(!$flag){echo"\n";}
            artoxml($val,$i+5);
            echo "$sp&lt;/".$key."&gt;\n";
        }else{
              echo "$val"."&lt;/".$key."&gt;\n";
         }
    }

}

Call the function with first argument as your array and the second argument must be 1, this will be increased for perfect indentation, and third must be true.

for example, if the array variable to be converted is $array1 then, calling would be, the calling function should be encapsulated with <pre> tag.

  artoxml($array1,1,true);   

Please see the page source after executing the file, because the < and > symbols won't be displayed in a html page.

You can make the border transparent. In this way it exists, but is invisible, so it doesn't push anything around:

.jobs .item {
   background: #eee;
   border: 1px solid transparent;
}

.jobs .item:hover {
   background: #e1e1e1;
   border: 1px solid #d0d0d0;
}

<div class="jobs">
  <div class="item">Item</div>
</div>

For elements that already have a border, and you don't want them to move, you can use negative margins:

.jobs .item {
    background: #eee;
    border: 1px solid #d0d0d0;
}

.jobs .item:hover {
   background: #e1e1e1;
    border: 3px solid #d0d0d0;
    margin: -2px;
}

<div class="jobs">
  <div class="item">Item</div>
</div>

Another possible trick for adding width to an existing border is to add a box-shadow with the spread attribute of the desired pixel width.

.jobs .item {
    background: #eee;
    border: 1px solid #d0d0d0;
}

.jobs .item:hover {
    background: #e1e1e1;
    box-shadow: 0 0 0 2px #d0d0d0;
}

<div class="jobs">
  <div class="item">Item</div>
</div>

MessageBox.Show(
  "your message",
  "window title", 
  MessageBoxButtons.OK, 
  MessageBoxIcon.Asterisk //For Info Asterisk
  MessageBoxIcon.Exclamation //For triangle Warning 
)

You can use the instanceof operator to test to see if it is a double prior to casting. You can then safely cast it to a double. In addition you can test it against other known types (e.g. Integer) and then coerce them into a double manually if desired.

    Double d = null;
    if (obj instanceof Double) {
        d = (Double) obj;
    }

There are new units that you can use:

vw - viewport width

vh - viewport height

#neo_main_container1
{
   width: 100%; //fallback
   width: 100vw;
}

This works for uppercase and lowercase. I don't know how elegant you deem it to be.

    rot=lambda x:chr(ord(x)+13) if chr(ord(x.lower())+13).isalpha()==True else chr(ord(x)-13)
    s=[rot(i) for i in filter(lambda x:x!=',',map(str,s))]
    return ''.join(s)

I think you just need to create your volume outside docker first with a docker create -v /location --name and then reuse it.

And by the time I used to use docker a lot, it wasn't possible to use a static docker volume with dockerfile definition so my suggestion is to try the command line (eventually with a script ) .

It will be something like this:

SELECT b.Title, b.Edition, b.Year, b.Pages, b.Rating, c.Category, p.Publisher, w.LastName
FROM
    Books b
    JOIN Categories_Book cb ON cb._ISBN = b._Books_ISBN
    JOIN Category c ON c._CategoryID = cb._Categories_Category_ID
    JOIN Publishers p ON p._PublisherID = b.PublisherID
    JOIN Writers_Books wb ON wb._Books_ISBN = b._ISBN
    JOIN Writer w ON w._WritersID = wb._Writers_WriterID

You use the join statement to indicate which fields from table A map to table B. I'm using aliases here thats why you see Books b the Books table will be referred to as b in the rest of the query. This makes for less typing.

FYI your naming convention is very strange, I would expect it to be more like this:

Book: ID, ISBN , BookTitle, Edition, Year, PublisherID, Pages, Rating
Category: ID, [Name]
BookCategory: ID, CategoryID, BookID
Publisher: ID, [Name]
Writer: ID, LastName
BookWriter: ID, WriterID, BookID

To get left and right tabs (now also with sideways) support for Bootstrap 3, bootstrap-vertical-tabs component can be used.

Assume you got a JSON like this

[
    {
        "type": "qrcode",
        "symbol": [
            {
                "seq": 0,
                "data": "HelloWorld9887725216",
                "error": null
            }
        ]
    }
]

To parse the above JSON in unity, you can create JSON model like this.

[System.Serializable]
public class QrCodeResult
{
    public QRCodeData[] result;
}

[System.Serializable]
public class Symbol
{
    public int seq;
    public string data;
    public string error;
}

[System.Serializable]
public class QRCodeData
{
    public string type;
    public Symbol[] symbol;
}

And then simply parse in the following manner...

var myObject = JsonUtility.FromJson<QrCodeResult>("{\"result\":" + jsonString.ToString() + "}");

Now you can modify the JSON/CODE according to your need. https://docs.unity3d.com/Manual/JSONSerialization.html

There is a plugin to check if an element is focused: http://plugins.jquery.com/project/focused

$('input').each(function(){
   if ($(this) == $.focused()) {
      $(this).addClass('focused');
   }
})

I will start with the copy answer of Ben Gripka:

public void Save(string FileName)
{
    using (var writer = new System.IO.StreamWriter(FileName))
    {
        var serializer = new XmlSerializer(this.GetType());
        serializer.Serialize(writer, this);
        writer.Flush();
    }
}

I used this code earlier. But reality showed that this solution is a bit problematic. Usually most of programmers just serialize setting on save and deserialize settings on load. This is an optimistic scenario. Once the serialization failed, because of some reason, the file is partly written, XML file is not complete and it is invalid. In consequence XML deserialization does not work and your application may crash on start. If the file is not huge, I suggest first serialize object to MemoryStream then write the stream to the File. This case is especially important if there is some complicated custom serialization. You can never test all cases.

public void Save(string fileName)
{
    //first serialize the object to memory stream,
    //in case of exception, the original file is not corrupted
    using (MemoryStream ms = new MemoryStream())
    {
        var writer = new System.IO.StreamWriter(ms);    
        var serializer = new XmlSerializer(this.GetType());
        serializer.Serialize(writer, this);
        writer.Flush();

        //if the serialization succeed, rewrite the file.
        File.WriteAllBytes(fileName, ms.ToArray());
    }
}

The deserialization in real world scenario should count with corrupted serialization file, it happens sometime. Load function provided by Ben Gripka is fine.

public static [ObjectType] Load(string fileName)
{
    using (var stream = System.IO.File.OpenRead(fileName))
    {
        var serializer = new XmlSerializer(typeof([ObjectType]));
        return serializer.Deserialize(stream) as [ObjectType];        
    }    
}

And it could be wrapped by some recovery scenario. It is suitable for settings files or other files which can be deleted in case of problems.

public static [ObjectType] LoadWithRecovery(string fileName)
{
    try
    {
        return Load(fileName);
    }
    catch(Excetion)
    {
        File.Delete(fileName); //delete corrupted settings file
        return GetFactorySettings();
    }
}

The following seems to work:

awk -F',[[:blank:]]*' '{$2=$2}1' OFS="," input.txt

A short way to reverse without additional libraries, imports, or static references.

int[] a = {1,2,3,4,5,6,7,23,9}, b; //compound declaration
var j = a.length;
b = new int[j];
for (var i : a)
    b[--j] = i; //--j so you don't have to subtract 1 from j. Otherwise you would get ArrayIndexOutOfBoundsException;
System.out.println(Arrays.toString(b));

Of course if you actually need a to be the reversed array just use

a = b; //after the loop

The OP refined his question to how a php script is called from a script. The php statement 'require' is good for dependancy as the script will stop if required script is not found.

#!/usr/bin/php
<?
require '/relative/path/to/someotherscript.php';

/* The above script runs as though executed from within this one. */

printf ("Hello world!\n");

?>

You need to call the AddAddress method once for every recipient. Like so:

$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..

Better yet, add them as Carbon Copy recipients.

$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddCC($email, $name);
}

Markup

<template lang="pug">
  form
    input.input(type='text', v-model='formData.firstName')
    input.input(type='text', v-model='formData.lastName')
    button(@click='resetForm', value='Reset Form') Reset Form
</template>

Script

<script>
  const initFromData = { firstName: '', lastName: '' };

  export default {
    data() {
      return {
        formData: Object.assign({}, initFromData),
      };
    },
    methods: {
      resetForm() {
        // if shallow copy
        this.formData = Object.assign({}, initFromData);

        // if deep copy
        // this.formData = JSON.parse(JSON.stringify(this.initFromData));
      },
    },
  };
</script>

Read the difference between a deep copy and a shallow copy HERE.

A simpler way would be to do:

ObjectA.Verify(
    a => a.Execute(
        It.Is<Params>(p => p.Id == 7)
    )
);

Instead of ((t[1])/length) * t[1] += string, you should use string += ((t[1])/length) * t[1]. (The other syntax issue - int is not iterable - will be your exercise to figure out.)

AFAIK, no such way. And there is also an ambiguity: what would you like to get as the answer if the same executable has multiple hard-links "pointing" to it? (Hard-links don't actually "point", they are the same file, just at another place in the file system hierarchy.)

Once execve() successfully executes a new binary, all information about the arguments to the original program is lost.

If you are using CocoaPods. Similar thing has happened to me. Although this question is old someone like me might still be struggling. So for to help: after pod install it warns you about project files. I didn't notice till now. it says:

[!] Please close any current Xcode sessions and use ProjectFile.xcworkspace for this project from now on.

So basically, do not continue working on .xcodeproj after installing Pods. If you do linker won't find files.

2012 This is a better solution for this scenario (tested With Visual Studio 2008):

Configuration config = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
config.AppSettings.Settings.Remove("MyVariable");
config.AppSettings.Settings.Add("MyVariable", "MyValue");
config.Save();

Update 2018 =>
Tested in vs 2015 - Asp.net MVC5

var config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
config.AppSettings.Settings["MyVariable"].Value = "MyValue";
config.Save();

if u need to checking element exist, use this code:

var config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
if (config.AppSettings.Settings["MyVariable"] != null)
{
config.AppSettings.Settings["MyVariable"].Value = "MyValue";
}
else { config.AppSettings.Settings.Add("MyVariable", "MyValue"); }
config.Save();

But if i take the piece of sql and run it from sql management studio, it will run without issue.

If you are at liberty to, change the service account to your own login, which would inherit your language/regional perferences.

The real crux of the issue is:

I use the following to convert -> date.Value.ToString("MM/dd/yyyy HH:mm:ss")

Please start using parameterized queries so that you won't encounter these issues in the future. It is also more robust, predictable and best practice.

Some thing like this.

If it is native code, you can disassemble it. But you wont see the original code as writte by the programmer. You will see the code produces by the compiler (assembler). This code is possibly optimized and although it is semantically equivalent, it can be much harder to read than normal ASM.

If it is bytecode (MSIL or javabytecode), there are decompiler which can product pretty good sourcecode. For .net, this would be reflector.

For Python 3 above, use:

sudo apt-get install python3-dateutil

You can use windows Powershell to execute a query and output it to a text file

Invoke-Sqlcmd -Query "Select * from database" -ServerInstance "Servername\SQL2008" -Database "DbName" > c:\Users\outputFileName.txt

The awk solution is what I would use, but if you want to understand your problems with bash, here is a revised version of your script.

#!/bin/bash -vx

##config file with ip addresses like 10.10.10.1:80
file=config.txt

while read line ; do
  ##this line is not correct, should strip :port and store to ip var
  ip=$( echo "$line" |cut -d\: -f1 )
  ping $ip
done < ${file}

You could write your top line as

for line in $(cat $file) ; do ...

(but not recommended).

You needed command substitution $( ... ) to get the value assigned to $ip

reading lines from a file is usually considered more efficient with the while read line ... done < ${file} pattern.

I hope this helps.

Felipsmartins is correct.

It is worth mentioning that it is because you cannot really use the -d/--data option if this is not a POST request. But this is still possible if you use the -G option.

Which means you can do this:

curl -X DELETE -G 'http://localhost:5000/locations' -d 'id=3'

Here it is a bit silly but when you are on the command line and you have a lot of parameters, it is a lot tidier.

I am saying this because cURL commands are usually quite long, so it is worth making it on more than one line escaping the line breaks.

curl -X DELETE -G \
'http://localhost:5000/locations' \
-d id=3 \
-d name=Mario \
-d surname=Bros

This is obviously a lot more comfortable if you use zsh. I mean when you need to re-edit the previous command because zsh lets you go line by line. (just saying)

Hope it helps.

string1.equals(string2) is the way.

It returns true if string1 is equals to string2 in value. Else, it will return false.

equals reference

My answer:

setTimeout((function(topicId) {
  return function() {
    postinsql(topicId);
  };
})(topicId), 4000);

Explanation:

The anonymous function created returns another anonymous function. This function has access to the originally passed topicId, so it will not make an error. The first anonymous function is immediately called, passing in topicId, so the registered function with a delay has access to topicId at the time of calling, through closures.

OR

This basically converts to:

setTimeout(function() {
  postinsql(topicId); // topicId inside higher scope (passed to returning function)
}, 4000);

EDIT: I saw the same answer, so look at his. But I didn't steal his answer! I just forgot to look. Read the explanation and see if it helps to understand the code.

As of JDK 8u102, the posted solutions relying on reflection will no longer work: the field that these solutions set is now final (https://bugs.openjdk.java.net/browse/JDK-8149417).

Looks like it's back to either (a) using Bouncy Castle, or (b) installing the JCE policy files.

This Regex should work too:

<script(?:(?!\/\/)(?!\/\*)[^'"]|"(?:\\.|[^"\\])*"|'(?:\\.|[^'\\])*'|\/\/.*(?:\n)|\/\*(?:(?:.|\s))*?\*\/)*?<\/script>

It even allows to have "problematic" variable strings like these inside:

<script type="text/javascript">
   var test1 = "</script>";
   var test2 = '\'</script>';
   var test1 = "\"</script>";
   var test1 = "<script>\"";
   var test2 = '<scr\'ipt>';
   /* </script> */
   // </script>
   /* ' */
   // var foo=" '
</script>

It seams that jQuery and Prototype fail on these ones...

Edit July 31 '17: Added a) non-capturing groups for better performance (and no empty groups) and b) support for JavaScript comments.

You can use the computeDistanceBetween() method in the google.maps.geometry.spherical namespace.

If you would like to use this for adding arrows/other icons to a button for example then you could use css pseudo-elements?

If it's really a background-image for the whole button, I tend to incorporate the spacing into the image, and just use

background-position: right 0;

But if I have to add for example a designed arrow to a button, I tend to have this html:

<a href="[url]" class="read-more">Read more</a>

And tend to do the following with CSS:

.read-more{
    position: relative;
    padding: 6px 15px 6px 35px;//to create space on the right
    font-size: 13px;
    font-family: Arial;
}

.read-more:after{
    content: '';
    display: block;
    width: 10px;
    height: 15px;
    background-image: url('../images/btn-white-arrow-right.png');
    position: absolute;
    right: 12px;
    top: 10px;
}

By using the :after selector, I add a element using CSS just to contain this small icon. You could do the same by just adding a span or <i> element inside the a-element. But I think this is a cleaner way of adding icons to buttons and it is cross-browser supported.

you can check out the fiddle here: http://codepen.io/anon/pen/PNzYzZ

You can directly export the query result with export option in the result grig. This export has various options to export. I think this will work.

See parallel. Its syntax is similar to xargs, but it runs the commands in parallel.

No, and the fact that you want to seems like a bad idea. Do you really need a default constructor like this?

Namenode enters into safemode when there is shortage of memory. As a result the HDFS becomes readable only. That means one can not create any additional directory or file in the HDFS. To come out of the safemode, the following command is used:

hadoop dfsadmin -safemode leave

If you are using cloudera manager:

go to >>Actions>>Leave Safemode

But it doesn't always solve the problem. The complete solution lies in making some space in the memory. Use the following command to check your memory usage.

free -m

If you are using cloudera, you can also check if the HDFS is showing some signs of bad health. It probably must be showing some memory issue related to the namenode. Allot more memory by following the options available. I am not sure what commands to use for the same if you are not using cloudera manager but there must be a way. Hope it helps! :)

You can easily implement clrscr() using simple for loop printing "\b".

Adding to what David Whittaker posted, I have created a query that generates the complete table and columns alter statement that will convert each table. It may be a good idea to run

SET SESSION group_concat_max_len = 100000;

first to make sure your group concat doesn't go over the very small limit as seen here.

     SELECT a.table_name, concat('ALTER TABLE ', a.table_schema, '.', a.table_name, ' DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_unicode_ci, ',
        group_concat(distinct(concat(' MODIFY ',  column_name, ' ', column_type, ' CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ', if (is_nullable = 'NO', ' NOT', ''), ' NULL ',
        if (COLUMN_DEFAULT is not null, CONCAT(' DEFAULT \'', COLUMN_DEFAULT, '\''), ''), if (EXTRA != '', CONCAT(' ', EXTRA), '')))), ';') as alter_statement
    FROM information_schema.columns a
    INNER JOIN INFORMATION_SCHEMA.TABLES b ON a.TABLE_CATALOG = b.TABLE_CATALOG
        AND a.TABLE_SCHEMA = b.TABLE_SCHEMA
        AND a.TABLE_NAME = b.TABLE_NAME
        AND b.table_type != 'view'
    WHERE a.table_schema = ? and (collation_name = 'latin1_swedish_ci' or collation_name = 'utf8mb4_general_ci')
    GROUP BY table_name;

A difference here between the previous answer is it was using utf8 instead of ut8mb4 and using t1.data_type with t1.CHARACTER_MAXIMUM_LENGTH didn't work for enums. Also, my query excludes views since those will have to altered separately.

I simply used a Perl script to return all these alters as an array and iterated over them, fixed the columns that were too long (generally they were varchar(256) when the data generally only had 20 characters in them so that was an easy fix).

I found some data was corrupted when altering from latin1 -> utf8mb4. It appeared to be utf8 encoded latin1 characters in columns would get goofed in the conversion. I simply held data from the columns I knew was going to be an issue in memory from before and after the alter and compared them and generated update statements to fix the data.

I would do this:

function Hello() {
  console.trace();
}

I found this question while I was stuck with the same query. I finally found it without using DbFunctions. Try this:

var q = db.Games.Where(t => t.StartDate.Day == DateTime.Now.Day && t.StartDate.Month == DateTime.Now.Month && t.StartDate.Year == DateTime.Now.Year ).OrderBy(d => d.StartDate);

This way by bifurcating the date parts we effectively compare only the dates, thus leaving out the time.

Hope that helps. Pardon me for the formatting in the answer, this is my first answer.

In the VSCode file tasks.json, the "command": "tsc" will try to find the tsc windows command script in some folder that it deems to be your modules folder.

If you know where the command npm install -g typescript or npm install typescript is saving to, I would recommend replacing:

"command": "tsc"

with

"command": "D:\\Projects\\TS\\Tutorial\\node_modules\\.bin\\tsc"

where D:\\...\\bin is the folder that contains my tsc windows executable

Will determine where my vscode is natively pointing to right now to find the tsc and fix it I guess.

Memory in SunHotSpot JVM is organized into three generations: young generation, old generation and permanent generation.

• Young Generation : the newly created objects are allocated to the young gen.
• Old Generation : If the new object requests for a larger heap space, it gets allocated directly into the old gen. Also objects which have survived a few GC cycles gets promoted to the old gen i.e long lived objects house in old gen.
• Permanent Generation : The permanent generation holds objects that the JVM finds convenient to have the garbage collector manage, such as objects describing classes and methods, as well as the classes and methods themselves.

FYI: The permanent gen is not considered a part of the Java heap.

How does the three generations interact/relate to each other? Objects(except the large ones) are first allocated to the young generation. If an object remain alive after x no. of garbage collection cycles it gets promoted to the old/tenured gen. Hence we can say that the young gen contains the short lived objects while the old gen contains the objects having a long life. The permanent gen does not interact with the other two generations.

The usual method I have seen is X.Y.Z, which generally corresponds to major.minor.patch:

• Major version numbers change whenever there is some significant change being introduced. For example, a large or potentially backward-incompatible change to a software package.
• Minor version numbers change when a new, minor feature is introduced or when a set of smaller features is rolled out.
• Patch numbers change when a new build of the software is released to customers. This is normally for small bug-fixes or the like.

Other variations use build numbers as an additional identifier. So you may have a large number for X.Y.Z.build if you have many revisions that are tested between releases. I use a couple of packages that are identified by year/month or year/release. Thus, a release in the month of September of 2010 might be 2010.9 or 2010.3 for the 3rd release of this year.

There are many variants to versioning. It all boils down to personal preference.

For the "1.3v1.1", that may be two different internal products, something that would be a shared library / codebase that is rev'd differently from the main product; that may indicate version 1.3 for the main product, and version 1.1 of the internal library / package.

$pristine/$dirty tells you whether the user actually changed anything, while $touched/$untouched tells you whether the user has merely been there/visited.

This is really useful for validation. The reason for $dirty was always to avoid showing validation responses until the user has actually visited a certain control. But, by using only the $dirty property, the user wouldn't get validation feedback unless they actually altered the value. So, an $invalid field still wouldn't show the user a prompt if the user didn't change/interact with the value. If the user entirely ignored a required field, everything looked OK.

With Angular 1.3 and ng-touched, you can now set a particular style on a control as soon as the user has blurred, regardless of whether they actually edited the value or not.

Here's a CodePen that shows the difference in behavior.

For me, the user was mongod instead of mongodb

sudo chown mongod:mongod /newlocation

You can see the logs for errors if the service fails:

/var/log/mongodb/mongod.log

Do you mean something like this:

HTML

<div class="row">
  <div class="container">

    <div class="col-md-4">
      left content
    </div>

    <div class="col-md-4 col-md-offset-4">

      <div class="yellow-background">
        text
        <div class="pull-right">right content</div>  
      </div>

    </div>
  </div>
</div>

CSS

.yellow-background {
  background: blue;
}

.pull-right {
  background: yellow;
}

A full example can be found on Codepen.

In some cases your image can be Alpine-based. In this case it will throw:

OCI runtime exec failed: exec failed: container_linux.go:348: starting container process caused "exec: \"bash\": executable file not found in $PATH": unknown

Because /bin/bash doesn't exist. Instead of this you should use:

docker exec -it 9f7d99aa6625 ash

or

docker exec -it 9f7d99aa6625 sh

The name accepted into TR1 (and the draft for the next standard) is std::unordered_map, so if you have that available, it's probably the one you want to use.

Other than that, using it is a lot like using std::map, with the proviso that when/if you traverse the items in an std::map, they come out in the order specified by operator<, but for an unordered_map, the order is generally meaningless.

There are two possible approaches; either you create a unique value and store somewhere along with the creation time, for example in a database, or you put the creation time inside the token so that you can decode it later and see when it was created.

To create a unique token:

string token = Convert.ToBase64String(Guid.NewGuid().ToByteArray());

Basic example of creating a unique token containing a time stamp:

byte[] time = BitConverter.GetBytes(DateTime.UtcNow.ToBinary());
byte[] key = Guid.NewGuid().ToByteArray();
string token = Convert.ToBase64String(time.Concat(key).ToArray());

To decode the token to get the creation time:

byte[] data = Convert.FromBase64String(token);
DateTime when = DateTime.FromBinary(BitConverter.ToInt64(data, 0));
if (when < DateTime.UtcNow.AddHours(-24)) {
  // too old
}

Note: If you need the token with the time stamp to be secure, you need to encrypt it. Otherwise a user could figure out what it contains and create a false token.

You can also use copy con [filename] in a Windows command window (cmd.exe):

C:\copy con yourfile.txt [enter]
C:\CTRL + Z [enter] //hold CTRL key & press "Z" then press Enter key.
^Z
    1 Files Copied.

This will create a file named yourfile.txt in the local directory.

You may try this

alist[0] = 2014

but if you are not sure about the position of 123 then you may try like this:

for idx, item in enumerate(alist):
   if 123 in item:
       alist[idx] = 2014

do this in global.asax.cs:

protected void Application_Start()
{
  //string ServerSoftware = Context.Request.ServerVariables["SERVER_SOFTWARE"];
  string server = Context.Request.ServerVariables["SERVER_NAME"];
  string port = Context.Request.ServerVariables["SERVER_PORT"];
  HttpRuntime.Cache.Insert("basePath", "http://" + server + ":" + port + "/");
  // ...
}

works like a charm. this.Context.Request is there...

this.Request throws exception intentionally based on a flag

In JavaScript, arrays and collections are different, although they are somewhat similar, but here the react needs an array. You need to create an array from the collection and apply it.

let homeArray = new Array(homes.length);
let i = 0

for (var key in homes) {
    homeArray[i] =  homes[key];
    i = i + 1;
}

nan means "not a number", a float value that you get if you perform a calculation whose result can't be expressed as a number. Any calculations you perform with NaN will also result in NaN.

inf means infinity.

For example:

>>> 2*float("inf")
inf
>>> -2*float("inf")
-inf
>>> float("inf")-float("inf")
nan

From 6.11. Boolean operations:

In the context of Boolean operations, and also when expressions are used by control flow statements, the following values are interpreted as false: False, None, numeric zero of all types, and empty strings and containers (including strings, tuples, lists, dictionaries, sets and frozensets). All other values are interpreted as true.

The key phrasing here that I think you are misunderstanding is "interpreted as false" or "interpreted as true". This does not mean that any of those values are identical to True or False, or even equal to True or False.

The expression '/bla/bla/bla' will be treated as true where a Boolean expression is expected (like in an if statement), but the expressions '/bla/bla/bla' is True and '/bla/bla/bla' == True will evaluate to False for the reasons in Ignacio's answer.

I have found the selected answer to have problems with upscaling, and so I have made (yet) another version (which I have tested):

public static Point scaleFit(Point src, Point bounds) {
  int newWidth = src.x;
  int newHeight = src.y;
  double boundsAspectRatio = bounds.y / (double) bounds.x;
  double srcAspectRatio = src.y / (double) src.x;

  // first check if we need to scale width
  if (boundsAspectRatio < srcAspectRatio) {
    // scale width to fit
    newWidth = bounds.x;
    //scale height to maintain aspect ratio
    newHeight = (newWidth * src.y) / src.x;
  } else {
    //scale height to fit instead
    newHeight = bounds.y;
    //scale width to maintain aspect ratio
    newWidth = (newHeight * src.x) / src.y;
  }

  return new Point(newWidth, newHeight);
}

Written in Android terminology :-)

as for the tests:

@Test public void scaleFit() throws Exception {
  final Point displaySize = new Point(1080, 1920);
  assertEquals(displaySize, Util.scaleFit(displaySize, displaySize));
  assertEquals(displaySize, Util.scaleFit(new Point(displaySize.x / 2, displaySize.y / 2), displaySize));
  assertEquals(displaySize, Util.scaleFit(new Point(displaySize.x * 2, displaySize.y * 2), displaySize));
  assertEquals(new Point(displaySize.x, displaySize.y * 2), Util.scaleFit(new Point(displaySize.x / 2, displaySize.y), displaySize));
  assertEquals(new Point(displaySize.x * 2, displaySize.y), Util.scaleFit(new Point(displaySize.x, displaySize.y / 2), displaySize));
  assertEquals(new Point(displaySize.x, displaySize.y * 3 / 2), Util.scaleFit(new Point(displaySize.x / 3, displaySize.y / 2), displaySize));
}

Here is an interesting article on Getting your C++ to the Web with Node.js

three general ways of integrating C++ code with a Node.js application - although there are lots of variations within each category:

1. Automation - call your C++ as a standalone app in a child process.
2. Shared library - pack your C++ routines in a shared library (dll) and call those routines from Node.js directly.
3. Node.js Addon - compile your C++ code as a native Node.js module/addon.

I have been trying different values with JSON.parse(value) and it seems to do the work:

// true
Boolean(JSON.parse("true"));
Boolean(JSON.parse("1"));
Boolean(JSON.parse(1));
Boolean(JSON.parse(true));

// false
Boolean(JSON.parse("0")); 
Boolean(JSON.parse(0));
Boolean(JSON.parse("false"));
Boolean(JSON.parse(false));

i had this problem yesterday. can you folow the local path in windows explorer?

To align some elements (headerElement) in the center and the last element to the right (headerEnd).

.headerElement {
    margin-right: 5%;
    margin-left: 5%;
}
.headerEnd{
    margin-left: auto;
}

Not an answer per se, but a guideline. Most of the time there is not much sense in declaring local T&& variable (as you did with std::vector<int>&& rval_ref). You will still have to std::move() them to use in foo(T&&) type methods. There is also the problem that was already mentioned that when you try to return such rval_ref from function you will get the standard reference-to-destroyed-temporary-fiasco.

Most of the time I would go with following pattern:

// Declarations
A a(B&&, C&&);
B b();
C c();

auto ret = a(b(), c());

You don't hold any refs to returned temporary objects, thus you avoid (inexperienced) programmer's error who wish to use a moved object.

auto bRet = b();
auto cRet = c();
auto aRet = a(std::move(b), std::move(c));

// Either these just fail (assert/exception), or you won't get 
// your expected results due to their clean state.
bRet.foo();
cRet.bar();

Obviously there are (although rather rare) cases where a function truly returns a T&& which is a reference to a non-temporary object that you can move into your object.

Regarding RVO: these mechanisms generally work and compiler can nicely avoid copying, but in cases where the return path is not obvious (exceptions, if conditionals determining the named object you will return, and probably couple others) rrefs are your saviors (even if potentially more expensive).

I've faced two different scenarios here:

1) When I want the asynchronous task to finish anyway: imagine my onPostExecute does store data received and then call a listener to update views so, to be more efficient, I want the task to finish anyway so I have the data ready when user cames back. In this case I usually do this:

@Override
protected void onPostExecute(void result) {
    // do whatever you do to save data
    if (this.getView() != null) {
        // update views
    }
}

2) When I want the asynchronous task only to finish when views can be updated: the case you're proposing here, the task only updates the views, no data storage needed, so it has no clue for the task to finish if views are not longer being showed. I do this:

@Override
protected void onStop() {
    // notice here that I keep a reference to the task being executed as a class member:
    if (this.myTask != null && this.myTask.getStatus() == Status.RUNNING) this.myTask.cancel(true);
    super.onStop();
}

I've found no problem with this, although I also use a (maybe) more complex way that includes launching tasks from the activity instead of the fragments.

Wish this helps someone! :)

For those with spaces in the path, you are going to want something like this: n.b. It expands out to an absolute path, rather than relative, so if your running directory path has spaces in, these count too.

set SOURCE=path\with spaces\to\my.log
FOR /F "usebackq delims=" %%A IN ("%SOURCE%") DO (
    ECHO %%A
)

To explain:

(path\with spaces\to\my.log)

Will not parse, because spaces. If it becomes:

("path\with spaces\to\my.log")

It will be handled as a string rather than a file path.

"usebackq delims=" 

See docs will allow the path to be used as a path (thanks to Stephan).

With most Awk implementations:

awk 'BEGIN {srand(); print srand()}'

In your .htaccess file , if you are using apache you can try with

ErrorDocument 404 http://www.domain.com/notFound.html

if anyone faced problem even after using return false; . then use the below.

setTimeout(function(){document.location.href = "index.php"},500);

Nope, this is not possible at all. There is no provision for it in the mailto: protocol, and it would be a gaping security hole if it were possible.

The best idea to send a file, but have the client send the E-Mail that I can think of is:

• Have the user choose a file
• Upload the file to a server
• Have the server return a random file name after upload
• Build a mailto: link that contains the URL to the uploaded file in the message body

Looks like you're a little bit confused about all that stuff.

operator is a built-in module providing a set of convenient operators. In two words operator.itemgetter(n) constructs a callable that assumes an iterable object (e.g. list, tuple, set) as input, and fetches the n-th element out of it.

So, you can't use key=a[x][1] there, because python has no idea what x is. Instead, you could use a lambda function (elem is just a variable name, no magic there):

a.sort(key=lambda elem: elem[1])

Or just an ordinary function:

def get_second_elem(iterable):
    return iterable[1]

a.sort(key=get_second_elem)

So, here's an important note: in python functions are first-class citizens, so you can pass them to other functions as a parameter.

Other questions:

1. Yes, you can reverse sort, just add reverse=True: a.sort(key=..., reverse=True)
2. To sort by more than one column you can use itemgetter with multiple indices: operator.itemgetter(1,2), or with lambda: lambda elem: (elem[1], elem[2]). This way, iterables are constructed on the fly for each item in list, which are than compared against each other in lexicographic(?) order (first elements compared, if equal - second elements compared, etc)
3. You can fetch value at [3,2] using a[2,1] (indices are zero-based). Using operator... It's possible, but not as clean as just indexing.

Refer to the documentation for details:

1. operator.itemgetter explained
2. Sorting list by custom key in Python

Thanks @haind

Yes HTMLInputElement worked for input field

//Example
var elem = e.currentTarget as HTMLInputElement;
elem.setAttribute('my-attribute','my value');
elem.value='5';

This HTMLInputElement is interface is inherit from HTMLElement which is inherited from EventTarget at root level. Therefore we can assert using as operator to use specific interfaces according to the context like in this case we are using HTMLInputElement for input field other interfaces can be HTMLButtonElement, HTMLImageElement etc.

For more reference you can check other available interface here

Use the -j option:

   -j     Store  just the name of a saved file (junk the path), and do not
          store directory names. By default, zip will store the full  path
          (relative to the current path).

Here's a a couple of useful link that I found when I started with JNI

http://en.wikipedia.org/wiki/Java_Native_Interface
http://download.oracle.com/javase/1.5.0/docs/guide/jni/spec/functions.html

concerning your problem you can use this

JNIEXPORT void JNICALL Java_ClassName_MethodName(JNIEnv *env, jobject obj, jstring javaString)   
{
   const char *nativeString = env->GetStringUTFChars(javaString, 0);

   // use your string

   env->ReleaseStringUTFChars(javaString, nativeString);
}

According to Extensible Messaging and Presence Protocol (Wikipedia), the standard TCP port for the server is 5222.

The client would presumably use the same ports as the messaging protocol, but can also use http (port 80) and https (port 443) for message delivery. These have the advantage of working for users behind firewalls, so your network admin should not need to get involved.

I have absolutely null skills in C, but for a simple parsing:

char* something = "123456";

int number = parseInt(something);

...this worked for me:

int parseInt(char* chars)
{
    int sum = 0;
    int len = strlen(chars);
    for (int x = 0; x < len; x++)
    {
        int n = chars[len - (x + 1)] - '0';
        sum = sum + powInt(n, x);
    }
    return sum;
}

int powInt(int x, int y)
{
    for (int i = 0; i < y; i++)
    {
        x *= 10;
    }
    return x;
}
