I've tried the code from above and made my own shadow which is little bit closer to what I am trying to achieve. Maybe it will help others too.

<selector xmlns:android="http://schemas.android.com/apk/res/android">

Apache Tomcat is used to deploy your Java Servlets and JSPs. So in your Java project you can build your WAR (short for Web ARchive) file, and just drop it in the deploy directory in Tomcat.

So basically Apache is an HTTP Server, serving HTTP. Tomcat is a Servlet and JSP Server serving Java technologies.

Tomcat includes Catalina, which is a servlet container. A servlet, at the end, is a Java class. JSP files (which are similar to PHP, and older ASP files) are generated into Java code (HttpServlet), which is then compiled to .class files by the server and executed by the Java virtual machine.

jQuery.val() and .text() will never return 'undefined' for an empty selection. It always returns an empty string (i.e. ""). .html() will return null if the element doesn't exist though.You need to do:

if(page_name != '')

For other variables that don't come from something like jQuery.val() you would do this though:

if(typeof page_name != 'undefined')

You just have to use the typeof operator.

Reset - On the commit-level, resetting is a way to move the tip of a branch to a different commit. This can be used to remove commits from the current branch.

Revert - Reverting undoes a commit by creating a new commit. This is a safe way to undo changes, as it has no chance of re-writing the commit history. Contrast this with git reset, which does alter the existing commit history. For this reason, git revert should be used to undo changes on a public branch, and git reset should be reserved for undoing changes on a private branch.

You can have a look on this link- Reset, Checkout and Revert

You can use below code

$.when( Typer() ).done(function() {
       playBGM();
});

Yes, that's the correct way to do it. If you're looking to give yourself a "Clean" (or, as I'd prefer to call it, "Empty" function), you can create an extension method.

public static void Empty(this System.IO.DirectoryInfo directory)
{
    foreach(System.IO.FileInfo file in directory.GetFiles()) file.Delete();
    foreach(System.IO.DirectoryInfo subDirectory in directory.GetDirectories()) subDirectory.Delete(true);
}

This will then allow you to do something like..

System.IO.DirectoryInfo directory = new System.IO.DirectoryInfo(@"C:\...");

directory.Empty();

The placeholder image you're including has a height of 50px. It is wrapped in an anchor (.navbar-brand) with a padding-top of 15px and a height of 50px. That's why the placeholder logo flows out of the bar. Try including a smaller image or play with the anchor's padding by assigning a class or an id to it wich you can reference in your css.

EDIT Or remove the static height: 50px from .navbar-brand. Your navbar will then take the height of its highest child.

h3 in bootstrap by default has a padding-top of 20px. Again, it is wrapped with that padding-top: 15px anchor. That's why it's not vertically centered like you want it. You could give the h3 a class or and id that resets the margin-top. And the same you could do with the padding of the anchor.

Here's something to play with: http://jsbin.com/jelec/1/edit?html,output

Or you can use the ^M+^J shortcut also. All a matter of preference. the "CTRL-CHAR" codes are translated by the compiler.

MyString := 'Hello,' + ^M + ^J + 'world!';

You can take the + away between the ^M and ^J, but then you will get a warning by the compiler (but it will still compile fine).

Specify the optional selector to target what you want:

jQuery(this).parent('li').addClass('yourClass');

Or:

jQuery(this).parents('li').addClass('yourClass');

KEY is normally a synonym for INDEX. The key attribute PRIMARY KEY can also be specified as just KEY when given in a column definition. This was implemented for compatibility with other database systems.

column_definition:
      data_type [NOT NULL | NULL] [DEFAULT default_value]
      [AUTO_INCREMENT] [UNIQUE [KEY] | [PRIMARY] KEY]
      ...

Ref: http://dev.mysql.com/doc/refman/5.1/en/create-table.html

Followed this.

I have solved it with adding some key in info.plist. The steps I followed are:

1. Opened my Projects info.plist file

2. Added a Key called NSAppTransportSecurity as a Dictionary.

3. Added a Subkey called NSAllowsArbitraryLoads as Boolean and set its value to YES as like following image.

Clean the Project and Now Everything is Running fine as like before.

const a = {
  foods: {
    dinner: 'Pasta'
  }
}
let b = JSON.parse(JSON.stringify(a))
b.foods.dinner = 'Soup'
console.log(b.foods.dinner) // Soup
console.log(a.foods.dinner) // Pasta

Using JSON.stringify and JSON.parse is the best way. Because by using the spread operator we will not get the efficient answer when the json object contains another object inside it. we need to manually specify that.

You are connecting via the SSH protocol, as indicated by the ssh:// prefix on your clone URL. Using SSH, every host has a key. Clients remember the host key associated with a particular address and refuse to connect if a host key appears to change. This prevents man in the middle attacks.

The host key for domain.com has changed. If this does not seem fishy to you, remove the old key from your local cache by editing ${HOME}/.ssh/known_hosts to remove the line for domain.com or letting an SSH utility do it for you with

ssh-keygen -R domain.com

From here, record the updated key either by doing it yourself with

ssh-keyscan -t rsa domain.com >> ~/.ssh/known_hosts

or, equivalently, let ssh do it for you next time you connect with git fetch, git pull, or git push (or even a plain ol’ ssh domain.com) by answering yes when prompted

The authenticity of host 'domain.com (a.b.c.d)' can't be established.
RSA key fingerprint is XX:XX:...:XX.
Are you sure you want to continue connecting (yes/no)?

The reason for this prompt is domain.com is no longer in your known_hosts after deleting it and presumably not in the system’s /etc/ssh/ssh_known_hosts, so ssh has no way to know whether the host on the other end of the connection is really domain.com. (If the wrong key is in /etc, someone with administrative privileges will have to update the system-wide file.)

I strongly encourage you to consider having users authenticate with keys as well. That way, ssh-agent can store key material for convenience (rather than everyone having to enter her password for each connection to the server), and passwords do not go over the network.

$header3 = @("Field_1","Field_2","Field_3","Field_4","Field_5")

            5 : "Kohli" }

And to retrieve values:

name = streetno.get(3, "default value")

Or

name = streetno[3]

That's using number as keys, put quotes around the numbers to use strings as keys.

In light of apparent dislike for how I've attempted to answer the OP's question. The literal answer is, a promise is something shared w/ other objects, while a deferred should be kept private. Primarily, a deferred (which generally extends Promise) can resolve itself, while a promise might not be able to do so.

If you're interested in the minutiae, then examine Promises/A+.

So far as I'm aware, the overarching purpose is to improve clarity and loosen coupling through a standardized interface. See suggested reading from @jfriend00:

Rather than directly passing callbacks to functions, something which can lead to tightly coupled interfaces, using promises allows one to separate concerns for code that is synchronous or asynchronous.

Personally, I've found deferred especially useful when dealing with e.g. templates that are populated by asynchronous requests, loading scripts that have networks of dependencies, and providing user feedback to form data in a non-blocking manner.

Indeed, compare the pure callback form of doing something after loading CodeMirror in JS mode asynchronously (apologies, I've not used jQuery in a while):

/* assume getScript has signature like: function (path, callback, context) 
   and listens to onload && onreadystatechange */
$(function () {
   getScript('path/to/CodeMirror', getJSMode);

   // onreadystate is not reliable for callback args.
   function getJSMode() {
       getScript('path/to/CodeMirror/mode/javascript/javascript.js', 
           ourAwesomeScript);
   };

   function ourAwesomeScript() {
       console.log("CodeMirror is awesome, but I'm too impatient.");
   };
});

To the promises formulated version (again, apologies, I'm not up to date on jQuery):

/* Assume getScript returns a promise object */
$(function () {
   $.when(
       getScript('path/to/CodeMirror'),
       getScript('path/to/CodeMirror/mode/javascript/javascript.js')
   ).then(function () {
       console.log("CodeMirror is awesome, but I'm too impatient.");
   });
});

Apologies for the semi-pseudo code, but I hope it makes the core idea somewhat clear. Basically, by returning a standardized promise, you can pass the promise around, thus allowing for more clear grouping.

This really belongs with @Ramnath's answer but I can't comment as I don't have enough reputation yet. You can also use the arrange function from the dplyr package in the same way as the plyr package.

library(dplyr)
arrange(DF, ID, desc(num))

Like this... I used it to read Chinese characters...

Dim reader as StreamReader = My.Computer.FileSystem.OpenTextFileReader(filetoimport.Text)
Dim a as String

Do
   a = reader.ReadLine
   '
   ' Code here
   '
Loop Until a Is Nothing

reader.Close()

Try this:

s = 'hello plombier pantin'
print (s.find('p'))
6
print (s.index('p'))
6
print (s.rindex('p'))
15
print (s.rfind('p'))

Consider using JSONPath https://packagist.org/packages/flow/jsonpath

There is a pretty clear explanation of how to use it and parse a JSON-file avoiding all the loops proposed. If you are familiar with XPath for XML you will start loving this approach.

Use atom-ctags as a package for C language with all things you need:

• Generated ctags for your project. Auto-complete.
• Go to declaration: Ctrl+Alt+Down and Alt+Click by default.
• There are customizable options for Click action.

This cross-browser lib seems safer - just zoom and moz-transform won't cover as many browsers as jquery.transform2d's scale().

http://louisremi.github.io/jquery.transform.js/

For example

$('#div').css({ transform: 'scale(.5)' });

Update

OK - I see people are voting this down without an explanation. The other answer here won't work in old Safari (people running Tiger), and it won't work consistently in some older browsers - that is, it does scale things but it does so in a way that's either very pixellated or shifts the position of the element in a way that doesn't match other browsers.

Or just look at this question, which this one is likely just a dupe of:

I found the easiest way is to use the colormap parameter in .plot() with one of the preset color gradients:

df.plot(kind='bar', stacked=True, colormap='Paired')

You can find a large list of preset colormaps here.

Here's a one-module Python replacement for perl -p:

# Provide compatibility with `perl -p`

# Usage:
#
#     python -mloop_over_stdin_lines '<program>'

# In, `<program>`, use the variable `line` to read and change the current line.

# Example:
#
#         python -mloop_over_stdin_lines 'line = re.sub("pattern", "replacement", line)'

# From the perlrun documentation:
#
#        -p   causes Perl to assume the following loop around your
#             program, which makes it iterate over filename arguments
#             somewhat like sed:
# 
#               LINE:
#                 while (<>) {
#                     ...             # your program goes here
#                 } continue {
#                     print or die "-p destination: $!\n";
#                 }
# 
#             If a file named by an argument cannot be opened for some
#             reason, Perl warns you about it, and moves on to the next
#             file. Note that the lines are printed automatically. An
#             error occurring during printing is treated as fatal. To
#             suppress printing use the -n switch. A -p overrides a -n
#             switch.
# 
#             "BEGIN" and "END" blocks may be used to capture control
#             before or after the implicit loop, just as in awk.
# 

import re
import sys

for line in sys.stdin:
    exec(sys.argv[1], globals(), locals())
    try:
        print line,
    except:
        sys.exit('-p destination: $!\n')

A Lay men's way is

on Main() rename the executing assembly file .exe to some thing else check date and time of created. and the updated file date time and copy to the application folder.

//Rename he executing file
System.IO.FileInfo file = new System.IO.FileInfo(System.Reflection.Assembly.GetExecutingAssembly().Location);

System.IO.File.Move(file.FullName, file.DirectoryName + "\\" + file.Name.Replace(file.Extension,"") + "-1" + file.Extension);

then do the logic check and copy the new file to executing folder

I too advise to use the simple way (KISS !-)

-- but some optimization could be found, namely not to test the length of an array more than once:

var elements = document.getElementsByTagName('div');
for (var i=0, im=elements.length; im>i; i++) {
    doSomething(elements[i]);
}

All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

A quick wrap up. Maybe someone has a better explanation.

A call stack is composed of 1 or many several stack frames. Each stack frame corresponds to a call to a function or procedure which has not yet terminated with a return.

To use a stack frame, a thread keeps two pointers, one is called the Stack Pointer (SP), and the other is called the Frame Pointer (FP). SP always points to the "top" of the stack, and FP always points to the "top" of the frame. Additionally, the thread also maintains a program counter (PC) which points to the next instruction to be executed.

The following are stored on the stack: local variables and temporaries, actual parameters of the current instruction (procedure, function, etc.)

There are different calling conventions regarding the cleaning of the stack.

Use DATENAME and wrap the logic in a Function, not a Stored Proc

declare @myTime as DateTime

set @myTime = GETDATE()

select @myTime

select DATENAME(day, @myTime) + SUBSTRING(UPPER(DATENAME(month, @myTime)), 0,4)

Returns "14OCT"

Try not to use any Character / String based operations if possible when working with dates. They are numerical (a float) and performance will suffer from those data type conversions.

Dig these handy conversions I have compiled over the years...

/* Common date functions */
--//This contains common date functions for MSSQL server

/*Getting Parts of a DateTime*/
    --//gets the date only, 20x faster than using Convert/Cast to varchar
    --//this has been especially useful for JOINS
    SELECT (CAST(FLOOR(CAST(GETDATE() as FLOAT)) AS DateTime))

    --//gets the time only (date portion is '1900-01-01' and is considered the "0 time" of dates in MSSQL, even with the datatype min value of 01/01/1753. 
    SELECT (GETDATE() - (CAST(FLOOR(CAST(GETDATE() as FLOAT)) AS DateTime)))


/*Relative Dates*/
--//These are all functions that will calculate a date relative to the current date and time
    /*Current Day*/
    --//now
    SELECT (GETDATE())

    --//midnight of today
    SELECT (DATEADD(ms,-4,(DATEADD(dd,DATEDIFF(dd,0,GETDATE()) + 1,0))))

    --//Current Hour
    SELECT DATEADD(hh,DATEPART(hh,GETDATE()),CAST(FLOOR(CAST(GETDATE() AS FLOAT)) as DateTime))

    --//Current Half-Hour - if its 9:36, this will show 9:30
    SELECT DATEADD(mi,((DATEDIFF(mi,(CAST(FLOOR(CAST(GETDATE() as FLOAT)) as DateTime)), GETDATE())) / 30) * 30,(CAST(FLOOR(CAST(GETDATE() as FLOAT)) as DateTime)))

    /*Yearly*/
    --//first datetime of the current year
    SELECT (DATEADD(yy,DATEDIFF(yy,0,GETDATE()),0))

    --//last datetime of the current year
    SELECT (DATEADD(ms,-4,(DATEADD(yy,DATEDIFF(yy,0,GETDATE()) + 1,0))))

    /*Monthly*/
    --//first datetime of current month
    SELECT (DATEADD(mm,DATEDIFF(mm,0,GETDATE()),0))

    --//last datetime of the current month
    SELECT (DATEADD(ms,-4,DATEADD(mm,1,DATEADD(mm,DATEDIFF(mm,0,GETDATE()),0))))

    --//first datetime of the previous month
    SELECT (DATEADD(mm,DATEDIFF(mm,0,GETDATE()) -1,0))

    --//last datetime of the previous month
    SELECT (DATEADD(ms, -4,DATEADD(mm,DATEDIFF(mm,0,GETDATE()),0)))

    /*Weekly*/
    --//previous monday at 12AM
    SELECT (DATEADD(wk,DATEDIFF(wk,0,GETDATE()) -1 ,0))

    --//previous friday at 11:59:59 PM
    SELECT (DATEADD(ms,-4,DATEADD(dd,5,DATEADD(wk,DATEDIFF(wk,0,GETDATE()) -1 ,0))))

    /*Quarterly*/
    --//first datetime of current quarter
    SELECT (DATEADD(qq,DATEDIFF(qq,0,GETDATE()),0))

    --//last datetime of current quarter
    SELECT (DATEADD(ms,-4,DATEADD(qq,DATEDIFF(qq,0,GETDATE()) + 1,0)))

The 'Z' is what adds the timezone info. As for output UTC, that seems to be the subject of some confusion -- people seem to gravitate toward moment.js.

Borrowing from this answer, you could do something like this without moment.js:

controller

var app1 = angular.module('app1',[]);

app1.controller('ctrl',['$scope',function($scope){

  var toUTCDate = function(date){
    var _utc = new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(),  date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
    return _utc;
  };

  var millisToUTCDate = function(millis){
    return toUTCDate(new Date(millis));
  };

    $scope.toUTCDate = toUTCDate;
    $scope.millisToUTCDate = millisToUTCDate;

  }]);

template

<html ng-app="app1">

  <head>
    <script data-require="angular.js@*" data-semver="1.2.12" src="http://code.angularjs.org/1.2.12/angular.js"></script>
    <link rel="stylesheet" href="style.css" />
    <script src="script.js"></script>
  </head>

  <body>
    <div ng-controller="ctrl">
      <div>
      utc {{millisToUTCDate(1400167800) | date:'dd-M-yyyy H:mm'}}
      </div>
      <div>
      local {{1400167800 | date:'dd-M-yyyy H:mm'}}
      </div>
    </div>
  </body>

</html>

here's plunker to play with it

See also this and this.

Also note that with this method, if you use the 'Z' from Angular's date filter, it seems it will still print your local timezone offset.

re.sub(r'(.)(.)',r"\2\1",'abcdef1234')

However re is a bit slow.

def swap(s):
    i=iter(s)
    while True:
        a,b=next(i),next(i)
        yield b
        yield a

''.join(swap("abcdef1234"))

Yes you can do it yourself. It is just a matter of grabbing the sources of the page and parsing them the way you want.

There are various possibilities. A good combo is using python-requests (built on top of urllib2, it is urllib.request in Python3) and BeautifulSoup4, which has its methods to select elements and also permits CSS selectors:

import requests
from BeautifulSoup4 import BeautifulSoup as bs
request = requests.get("http://foo.bar")
soup = bs(request.text) 
some_elements = soup.find_all("div", class_="myCssClass")

Some will prefer xpath parsing or jquery-like pyquery, lxml or something else.

When the data you want is produced by some JavaScript, the above won't work. You either need python-ghost or Selenium. I prefer the latter combined with PhantomJS, much lighter and simpler to install, and easy to use:

from selenium import webdriver
client = webdriver.PhantomJS()
client.get("http://foo")
soup = bs(client.page_source)

I would advice to start your own solution. You'll understand Scrapy's benefits doing so.

ps: take a look at scrapely: https://github.com/scrapy/scrapely

pps: take a look at Portia, to start extracting information visually, without programming knowledge: https://github.com/scrapinghub/portia

In addition to the repository permissions, the /tmp directory must also be writeable by all users.

Do you have several swf-files? If your class is imported in one of the swf's, other swf's will also use the same version of the class. One old import with * in one swf will do it. Recompile everything and see if it works.

Try Like this :

TextView text=(TextView)findViewById(R.id.textviewID);
text.setText("Text");

Instead of this:

text = (EditText) findViewById(R.id.this_is_the_id_of_textview);
text.setText("TEST");

Use the keyword and, not & because & is a bit operator.

Be careful with this... just so you know, in Java and C++, the & operator is ALSO a bit operator. The correct way to do a boolean comparison in those languages is &&. Similarly | is a bit operator, and || is a boolean operator. In Python and and or are used for boolean comparisons.

I use it for two reasons:

1. I can force a refresh of the icon by adding a query parameter for example ?v=2. like this: <link rel="icon" href="/favicon.ico?v=2" type="image/x-icon" />

2. In case I need to specify the path.

Always remember that in case of checked exception you can catch only after throwing the exception(either you throw or any inbuilt method used in your code can throw) ,but in case of unchecked exception You an catch even when you have not thrown that exception.

In my case, setting url: '' in ajax settings would result in a status code 0 in ie8.. It seems ie just doesn't tolerate such a setting.

From Chris Coyier's article on centering percentage width elements:

Instead of using negative margins, you use negative translate() transforms.

.center {
  position: absolute;
  left: 50%;
  top: 50%;

  /*
  Nope =(
  margin-left: -25%;
  margin-top: -25%;
  */

  /* 
  Yep!
  */
  transform: translate(-50%, -50%);

  /*
  Not even necessary really. 
  e.g. Height could be left out!
  */
  width: 40%;
  height: 50%;
}

Installing the aab directly from the device, I couldn't find a way for that.

But there is a way to install it through your command line using the following documentation You can install apk to a device through BundleTool

According to "@Albert Vila Calvo" comment he noted that to install bundletools using HomeBrew use brew install bundletool

You can now install extract apks from aab file and install it to a device

Extracting apk files from through the next command

java -jar bundletool-all-0.3.3.jar build-apks --bundle=bundle.aab --output=app.apks --ks=my-release-key.keystore --ks-key-alias=alias --ks-pass=pass:password

Arguments:

• --bundle -> Android Bundle .aab file
• --output -> Destination and file name for the generated apk file
• --ks -> Keystore file used to generate the Android Bundle
• --ks-key-alias -> Alias for keystore file
• --ks-pass -> Password for Alias file (Please note the 'pass' prefix before password value)

Then you will have a file with extension .apks So now you need to install it to a device

java -jar bundletool-all-0.6.0.jar install-apks --adb=/android-sdk/platform-tools/adb --apks=app.apks

Arguments:

• --adb -> Path to adb file
• --apks -> Apks file need to be installed

<select name="FakeName" id="Fake-ID" aria-required="true" required>  <?php $options=nl2br(file_get_contents("employees.txt")); $options=explode("<br />",$options);  foreach ($options as $item_array) { echo "<option value='".$item_array"'>".$item_array"</option>";  } ?> </select> 

Your .vimrc file goes in your $HOME directory. In *nix, cd ~; vim .vimrc. The commands in the .vimrc are the same as you type in ex-mode in vim, only without the leading colon, so colo evening would suffice. Comments in the .vimrc are indicated with a leading double-quote.

To see an example vimrc, open $VIMRUNTIME/vimrc_example.vim from within vim

:e $VIMRUNTIME/vimrc_example.vim

Role of a metaclass' __call__() method when creating a class instance

If you've done Python programming for more than a few months you'll eventually stumble upon code that looks like this:

# define a class
class SomeClass(object):
    # ...
    # some definition here ...
    # ...

# create an instance of it
instance = SomeClass()

# then call the object as if it's a function
result = instance('foo', 'bar')

The latter is possible when you implement the __call__() magic method on the class.

class SomeClass(object):
    # ...
    # some definition here ...
    # ...

    def __call__(self, foo, bar):
        return bar + foo

The __call__() method is invoked when an instance of a class is used as a callable. But as we've seen from previous answers a class itself is an instance of a metaclass, so when we use the class as a callable (i.e. when we create an instance of it) we're actually calling its metaclass' __call__() method. At this point most Python programmers are a bit confused because they've been told that when creating an instance like this instance = SomeClass() you're calling its __init__() method. Some who've dug a bit deeper know that before __init__() there's __new__(). Well, today another layer of truth is being revealed, before __new__() there's the metaclass' __call__().

Let's study the method call chain from specifically the perspective of creating an instance of a class.

This is a metaclass that logs exactly the moment before an instance is created and the moment it's about to return it.

class Meta_1(type):
    def __call__(cls):
        print "Meta_1.__call__() before creating an instance of ", cls
        instance = super(Meta_1, cls).__call__()
        print "Meta_1.__call__() about to return instance."
        return instance

This is a class that uses that metaclass

class Class_1(object):

    __metaclass__ = Meta_1

    def __new__(cls):
        print "Class_1.__new__() before creating an instance."
        instance = super(Class_1, cls).__new__(cls)
        print "Class_1.__new__() about to return instance."
        return instance

    def __init__(self):
        print "entering Class_1.__init__() for instance initialization."
        super(Class_1,self).__init__()
        print "exiting Class_1.__init__()."

And now let's create an instance of Class_1

instance = Class_1()
# Meta_1.__call__() before creating an instance of <class '__main__.Class_1'>.
# Class_1.__new__() before creating an instance.
# Class_1.__new__() about to return instance.
# entering Class_1.__init__() for instance initialization.
# exiting Class_1.__init__().
# Meta_1.__call__() about to return instance.

Observe that the code above doesn't actually do anything more than logging the tasks. Each method delegates the actual work to its parent's implementation, thus keeping the default behavior. Since type is Meta_1's parent class (type being the default parent metaclass) and considering the ordering sequence of the output above, we now have a clue as to what would be the pseudo implementation of type.__call__():

class type:
    def __call__(cls, *args, **kwarg):

        # ... maybe a few things done to cls here

        # then we call __new__() on the class to create an instance
        instance = cls.__new__(cls, *args, **kwargs)

        # ... maybe a few things done to the instance here

        # then we initialize the instance with its __init__() method
        instance.__init__(*args, **kwargs)

        # ... maybe a few more things done to instance here

        # then we return it
        return instance

We can see that the metaclass' __call__() method is the one that's called first. It then delegates creation of the instance to the class's __new__() method and initialization to the instance's __init__(). It's also the one that ultimately returns the instance.

From the above it stems that the metaclass' __call__() is also given the opportunity to decide whether or not a call to Class_1.__new__() or Class_1.__init__() will eventually be made. Over the course of its execution it could actually return an object that hasn't been touched by either of these methods. Take for example this approach to the singleton pattern:

class Meta_2(type):
    singletons = {}

    def __call__(cls, *args, **kwargs):
        if cls in Meta_2.singletons:
            # we return the only instance and skip a call to __new__()
            # and __init__()
            print ("{} singleton returning from Meta_2.__call__(), "
                   "skipping creation of new instance.".format(cls))
            return Meta_2.singletons[cls]

        # else if the singleton isn't present we proceed as usual
        print "Meta_2.__call__() before creating an instance."
        instance = super(Meta_2, cls).__call__(*args, **kwargs)
        Meta_2.singletons[cls] = instance
        print "Meta_2.__call__() returning new instance."
        return instance

class Class_2(object):

    __metaclass__ = Meta_2

    def __new__(cls, *args, **kwargs):
        print "Class_2.__new__() before creating instance."
        instance = super(Class_2, cls).__new__(cls)
        print "Class_2.__new__() returning instance."
        return instance

    def __init__(self, *args, **kwargs):
        print "entering Class_2.__init__() for initialization."
        super(Class_2, self).__init__()
        print "exiting Class_2.__init__()."

Let's observe what happens when repeatedly trying to create an object of type Class_2

a = Class_2()
# Meta_2.__call__() before creating an instance.
# Class_2.__new__() before creating instance.
# Class_2.__new__() returning instance.
# entering Class_2.__init__() for initialization.
# exiting Class_2.__init__().
# Meta_2.__call__() returning new instance.

b = Class_2()
# <class '__main__.Class_2'> singleton returning from Meta_2.__call__(), skipping creation of new instance.

c = Class_2()
# <class '__main__.Class_2'> singleton returning from Meta_2.__call__(), skipping creation of new instance.

a is b is c # True

It depends on the web application being loaded. Try some of the approaches below:

Set higher render priority (deprecated from API 18+):

webview.getSettings().setRenderPriority(RenderPriority.HIGH);

Enable/disable hardware acceleration:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    // chromium, enable hardware acceleration
    webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
} else {
    // older android version, disable hardware acceleration
    webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}

Disable the cache (if you have problems with your content):

webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

I found this from my friend, very effective if you are looking for all the table's primary keys under particular schema.

SELECT tc.constraint_name AS IndexName,tc.table_name AS TableName,tc.table_schema
AS SchemaName,kc.column_name AS COLUMN_NAME
FROM information_schema.table_constraints tc,information_schema.key_column_usage kc
WHERE tc.constraint_type = 'PRIMARY KEY' AND kc.table_name = tc.table_name AND kc.table_schema = tc.table_schema
AND kc.constraint_name = tc.constraint_name AND tc.table_schema='<SCHEMA_NAME>'

Here is an handy solution! I'm using SQL Server 2008 R2.

As you want to modify the FK constraint by adding ON DELETE/UPDATE CASCADE, follow these steps:

NUMBER 1:

Right click on the constraint and click to Modify

NUMBER 2:

Choose your constraint on the left side (if there are more than one). Then on the right side, collapse "INSERT And UPDATE Specification" point and specify the actions on Delete Rule or Update Rule row to suit your need. After that, close the dialog box.

NUMBER 3:

The final step is to save theses modifications (of course!)

PS: It's saved me from a bunch of work as I want to modify a primary key referenced in another table.

I am not the OP of this answer but it helped me so:

I wanted to change the color of the next/previous buttons of the bootstrap carousel on my homepage.

Solution: Copy the selector names from bootstrap.css and move them to your own style.css (with your own prefrences..) :

.carousel-control-prev-icon,
.carousel-control-next-icon {
  height: 100px;
  width: 100px;
  outline: black;
  background-size: 100%, 100%;
  border-radius: 50%;
  border: 1px solid black;
  background-image: none;
}

.carousel-control-next-icon:after
{
  content: '>';
  font-size: 55px;
  color: red;
}

.carousel-control-prev-icon:after {
  content: '<';
  font-size: 55px;
  color: red;
}

This is what i've implemented:

$(window).resize(function(){ setTimeout(someFunction, 500); });

we can clear the setTimeout if we expect resize to happen less than 500ms

Good Luck...

They are extension methods. Welcome to a whole new fluent world. :)

This should work as well

text = 'the car? was big and* red!'

newtext = re.sub( '[^a-z0-9]', ' ', text)

print(newtext)

the car was big and red

It is common for comparison functions to return 0 on "equals", so that they can also return a negative number for "less than" and a positive number for "greater than". strcmp() and memcmp() work like this.

It is, however, idiomatic for zero to be false and nonzero to be true, because this is how the C flow control and logical boolean operators work. So it might be that the return values chosen for this function are fine, but it is the function's name that is in error (it should really just be called compare() or similar).

Every programming language has its own set of rules and conventions for the kinds of names that you're allowed to use, and the Java programming language is no different. The rules and conventions for naming your variables can be summarized as follows:

• Variable names are case-sensitive. A variable's name can be any legal identifier — an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign "$", or the underscore character "_". The convention, however, is to always begin your variable names with a letter, not "$" or "_". Additionally, the dollar sign character, by convention, is never used at all. You may find some situations where auto-generated names will contain the dollar sign, but your variable names should always avoid using it. A similar convention exists for the underscore character; while it's technically legal to begin your variable's name with "_", this practice is discouraged. White space is not permitted.

• Subsequent characters may be letters, digits, dollar signs, or underscore characters. Conventions (and common sense) apply to this rule as well. When choosing a name for your variables, use full words instead of cryptic abbreviations. Doing so will make your code easier to read and understand. In many cases it will also make your code self-documenting; fields named cadence, speed, and gear, for example, are much more intuitive than abbreviated versions, such as s, c, and g. Also keep in mind that the name you choose must not be a keyword or reserved word.

• If the name you choose consists of only one word, spell that word in all lowercase letters. If it consists of more than one word, capitalize the first letter of each subsequent word. The names gearRatio and currentGear are prime examples of this convention. If your variable stores a constant value, such as static final int NUM_GEARS = 6, the convention changes slightly, capitalizing every letter and separating subsequent words with the underscore character. By convention, the underscore character is never used elsewhere.

It seems the mysql connectivity library is not included in the project. Solve the problem following one of the proposed solutions:

• MAVEN PROJECTS SOLUTION

Add the mysql-connector dependency to the pom.xml project file:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.39</version>
</dependency>

Here you are all the versions: https://mvnrepository.com/artifact/mysql/mysql-connector-java

• ALL PROJECTS SOLUTION

Add the jar library manually to the project.

Right Click the project -- > build path -- > configure build path

In Libraries Tab press Add External Jar and Select your jar.

You can find zip for mysql-connector here

• Explanation:

When building the project, java throws you an exception because a file (the com.mysql.jdbc.Driver class) from the mysql connectivity library is not found. The solution is adding the library to the project, and java will find the com.mysql.jdbc.Driver

Do:

con.query('SET GLOBAL connect_timeout=28800')
con.query('SET GLOBAL interactive_timeout=28800')
con.query('SET GLOBAL wait_timeout=28800')

Parameter meaning (taken from MySQL Workbench in Navigator: Instance > Options File > Tab "Networking" > Section "Timeout Settings")

• connect_timeout: Number of seconds the mysqld server waits for a connect packet before responding with 'Bad handshake'
• interactive_timeout Number of seconds the server waits for activity on an interactive connection before closing it
• wait_timeout Number of seconds the server waits for activity on a connection before closing it

BTW: 28800 seconds are 8 hours, so for a 10 hour execution time these values should be actually higher.

our project surely is configured as "library" thats why you get the message : "Android library projects cannot be launched."

right-click in your project and select Properties. In the Properties window -> "Android" -> uncheck the option "is Library" and apply -> Click "ok" to close the properties window.

I used this answer with my local directory ( for example E:// ) it is worked fine for the first directory and for the seconde directory the output made a java null pointer exception, after searching for the reason i discover that the problem was created by the hidden directory, and this directory was created by windows to avoid this problem just use this

public void recursiveSearch(File file ) {
 File[] filesList = file.listFiles();
    for (File f : filesList) {
        if (f.isDirectory() && !f.isHidden()) {
            System.out.println("Directoy name is  -------------->" + f.getName());
            recursiveSearch(f);
        }
        if( f.isFile() ){
            System.out.println("File name is  -------------->" + f.getName());
        }
    }
}

You can as well do:

git checkout --theirs /path/to/file

to keep the remote file, and:

git checkout --ours /path/to/file

to keep local file.

Then git add them and everything is done.

Edition: Keep in mind that this is for a merge scenario. During a rebase --theirs refers to the branch where you've been working.

Try this one.

  String[] array1= new String[]{};
  System.out.println(array1.length);
  String[] array2= new String[0];
  System.out.println(array2.length);

Note: there is no byte code difference between new String[]{}; and new String[0];

new String[]{} is array initialization with values.

new String[0]; is array declaration(only allocating memory)

new String[10]{}; is not allowed because new String[10]{ may be here 100 values};

RegEx to match everything between two strings using the Java approach.

List<String> results = new ArrayList<>(); //For storing results
String example = "Code will save the world";

Let's use Pattern and Matcher objects to use RegEx (.?)*.

Pattern p = Pattern.compile("Code "(.*?)" world");   //java.util.regex.Pattern;
Matcher m = p.matcher(example);                      //java.util.regex.Matcher;

Since Matcher might contain more than one match, we need to loop over the results and store it.

while(m.find()){   //Loop through all matches
   results.add(m.group()); //Get value and store in collection.
}

This example will contain only "will save the" word, but in the bigger text it will probably find more matches.

When passing a struct to another function, it would usually be better to do as Donnell suggested above and pass it by reference instead.

A very good reason for this is that it makes things easier if you want to make changes that will be reflected when you return to the function that created the instance of it.

Here is an example of the simplest way to do this:

#include <stdio.h>

typedef struct student {
    int age;
} student;

void addStudent(student *s) {
    /* Here we can use the arrow operator (->) to dereference 
       the pointer and access any of it's members: */
    s->age = 10;
}

int main(void) {

    student aStudent = {0};     /* create an instance of the student struct */
    addStudent(&aStudent);      /* pass a pointer to the instance */

    printf("%d", aStudent.age);

    return 0;
}

In this example, the argument for the addStudent() function is a pointer to an instance of a student struct - student *s. In main(), we create an instance of the student struct and then pass a reference to it to our addStudent() function using the reference operator (&).

In the addStudent() function we can make use of the arrow operator (->) to dereference the pointer, and access any of it's members (functionally equivalent to: (*s).age).

Any changes that we make in the addStudent() function will be reflected when we return to main(), because the pointer gave us a reference to where in the memory the instance of the student struct is being stored. This is illustrated by the printf(), which will output "10" in this example.

Had you not passed a reference, you would actually be working with a copy of the struct you passed in to the function, meaning that any changes would not be reflected when you return to main - unless you implemented a way of passing the new version of the struct back to main or something along those lines!

Although pointers may seem off-putting at first, once you get your head around how they work and why they are so handy they become second nature, and you wonder how you ever coped without them!

Personnaly I like to do all the initialisations in the constructor

public Test()
{
  symbolsPresent = new ArrayList<String>();
  symbolsPresent.add("ONE");
  symbolsPresent.add("TWO");
  symbolsPresent.add("THREE");
  symbolsPresent.add("FOUR");
}

Edit : It is a choice of course and others prefer to initialize in the declaration. Both are valid, I have choosen the constructor because all type of initialitions are possible there (if you need a loop or parameters, ...). However I initialize the constants in the declaration on the top on the source.
The most important is to follow a rule that you like and be consistent in our classes.

Have you updated the firmware version of the iPhone you are testing on?

In my case it was a very silly error. I was using a library to read the connection string out of a config file, and I forgot to double back slash.

For example I had: localhost\sqlexpress which was read as localhostsqlexpress when I should rather have had localhost\\sqlexpress note the \

Add following code in app.js of NODEJ Restful api to avoid "Access-Control-Allow-Origin" error in angular 6 or any other framework

The other answers here presuppose that you have a regex engine which supports non-greedy matching, which is an extension introduced in Perl 5 and widely copied to other modern languages; but it is by no means ubiquitous.

Many older or more conservative languages and editors only support traditional regular expressions, which have no mechanism for controlling greediness of the repetition operator * - it always matches the longest possible string.

The trick then is to limit what it's allowed to match in the first place. Instead of .* you seem to be looking for

[^>]*

which still matches as many of something as possible; but the something is not just . "any character", but instead "any character which isn't >".

Depending on your application, you may or may not want to enable an option to permit "any character" to include newlines.

Even if your regular expression engine supports non-greedy matching, it's better to spell out what you actually mean. If this is what you mean, you should probably say this, instead of rely on non-greedy matching to (hopefully, probably) Do What I Mean.

For example, a regular expression with a trailing context after the wildcard like .*?><br/> will jump over any nested > until it finds the trailing context (here, ><br/>) even if that requires straddling multiple > instances and newlines if you let it, where [^>]*><br/> (or even [^\n>]*><br/> if you have to explicitly disallow newline) obviously can't and won't do that.

Of course, this is still not what you want if you need to cope with <img title="quoted string with > in it" src="other attributes"> and perhaps <img title="nested tags">, but at that point, you should finally give up on using regular expressions for this like we all told you in the first place.

If you use DATETIME2 you may find you have to pass the parameter in specifically as DATETIME2, otherwise it may helpfully convert it to DATETIME and have the same issue.

Please try the below query. Use sys.columns to get the details :-

WHERE c.name LIKE '%MyCol%';

Coming From a Hybrid Application POV. This is a javascript example, I have a Update Available footer on my main menu. If an update is available (ie. my version number within the config file is less than the version retrieved, display the footer) This will then direct the user to the app/play store, where the user can then click the update button.

I also get the whats new data (ie Release Notes) and display these in a modal on login if its the first time on this version.

On device Ready, set your store URL

        if (device.platform == 'iOS')
           storeURL = 'https://itunes.apple.com/lookup?bundleId=BUNDLEID';
        else
           storeURL = 'https://play.google.com/store/apps/details?id=BUNDLEID';

The Update Available method can be ran as often as you like. Mine is ran every time the user navigates to the home screen.

function isUpdateAvailable() {
    if (device.platform == 'iOS') {
        $.ajax(storeURL, {
            type: "GET",
            cache: false,
            dataType: 'json'
        }).done(function (data) {
            isUpdateAvailable_iOS(data.results[0]);
        }).fail(function (jqXHR, textStatus, errorThrown) {
            commsErrorHandler(jqXHR, textStatus, false);
        });
    } else {
        $.ajax(storeURL, {
            type: "GET",
            cache: false
        }).done(function (data) {
            isUpdateAvailable_Android(data);
        }).fail(function (jqXHR, textStatus, errorThrown) {
            commsErrorHandler(jqXHR, textStatus, false);
        });
    }
}

iOS Callback: Apple have an API, so very easy to get

function isUpdateAvailable_iOS (data) {
    var storeVersion = data.version;
    var releaseNotes = data.releaseNotes;
    // Check store Version Against My App Version ('1.14.3' -> 1143)
    var _storeV = parseInt(storeVersion.replace(/\./g, ''));
    var _appV = parseInt(appVersion.substring(1).replace(/\./g, ''));
    $('#ft-main-menu-btn').off();
    if (_storeV > _appV) {
        // Update Available
        $('#ft-main-menu-btn').text('Update Available');
        $('#ft-main-menu-btn').click(function () {
            openStore();
        });

    } else {
        $('#ft-main-menu-btn').html(' ');
        // Release Notes
        settings.updateReleaseNotes('v' + storeVersion, releaseNotes);
    }
}

Android Callback: PlayStore you have to scrape, as you can see the version is relatively easy to grab and the whats new i take the html instead of the text as this way I can use their formatting (ie new lines etc)

function isUpdateAvailable_Android(data) {
    var html = $(data);
    var storeVersion = html.find('div[itemprop=softwareVersion]').text().trim();
    var releaseNotes = html.find('.whatsnew')[0].innerHTML;
    // Check store Version Against My App Version ('1.14.3' -> 1143)
    var _storeV = parseInt(storeVersion.replace(/\./g, ''));
    var _appV = parseInt(appVersion.substring(1).replace(/\./g, ''));
    $('#ft-main-menu-btn').off();
    if (_storeV > _appV) {
        // Update Available
        $('#ft-main-menu-btn').text('Update Available');
        $('#ft-main-menu-btn').click(function () {
            openStore();
        });

    } else {
        $('#ft-main-menu-btn').html(' ');
        // Release Notes
        settings.updateReleaseNotes('v' + storeVersion, releaseNotes);
    }
}

The open store logic is straight forward, but for completeness

function openStore() {
    var url = 'https://itunes.apple.com/us/app/appname/idUniqueID';
    if (device.platform != 'iOS')
       url = 'https://play.google.com/store/apps/details?id=appid'
   window.open(url, '_system')
}

Ensure Play Store and App Store have been Whitelisted:

  <access origin="https://itunes.apple.com"/>
  <access origin="https://play.google.com"/>

The problem is caused because the code is accessing a lazy JPA relation when the "connection" to the database is closed (persistence context is the correct name in terms of Hibernate/JPA).

A simple way of solving it in Spring Boot is by defining a service layer and using the @Transactional annotation. This annotation in a method creates a transaction that propagates into the repository layer and keeps open the persistence context until the method finish. If you access the collection inside the transactional method Hibernate/JPA will fetch the data from the database.

In your case, you just need to annotate with @Transactional the method findTopicByID(id) in your TopicService and force the fetch of the collection in that method (for instance, by asking its size):

    @Transactional(readOnly = true)
    public Topic findTopicById(Long id) {
        Topic topic = TopicRepository.findById(id).orElse(null);
        topic.getComments().size();
        return topic;
    }

It should probably also be mentioned that you can simply chain a catch() function after the call of your async operation because under the hood still a promise is returned.

await foo().catch(error => console.log(error));

This way you can avoid the try/catch syntax if you do not like it.

.toggleClass() will not animate, you should go for slideToggle() or .animate() method.

To send an mms for Android 4.0 api 14 or higher without permission to write apn settings, you can use this library: Retrieve mnc and mcc codes from android, then call

Carrier c = Carrier.getCarrier(mcc, mnc);
if (c != null) {
    APN a = c.getAPN();
    if (a != null) {
        String mmsc = a.mmsc;
        String mmsproxy = a.proxy; //"" if none
        int mmsport = a.port; //0 if none
    }
}

To use this, add Jsoup and droid prism jar to the build path, and import com.droidprism.*;

The difference is in the subsystem that each executable targets.

• java.exe targets the CONSOLE subsystem.
• javaw.exe targets the WINDOWS subsystem.

Basically, all Maven is telling you is that certain dependencies in your project are not available in the central maven repository. The default is to look in your local .m2 folder (local repository), and then any configured repositories in your POM, and then the central maven repository. Look at the repositories section of the Maven reference.

The problem is that the project that was checked in didn't configure the POM in such a way that all the dependencies could be found and the project could be built from scratch.

I was trying something similar to ensure the -ggdb flag was present.

Call make in a clean directory and grep the flag you are looking for. Looking for debug rather than ggdb I would just write.

make VERBOSE=1 | grep debug

The -ggdb flag was obscure enough that only the compile commands popped up.

As per the above answers, it works well.

If we paste curl requests with Authorization data in import, Postman will set all headers automatically. We only just pass row JSON data in the request body if needed or Upload images through form-data in the body.

This is just an example. Your API should be a different one (if your API allows)

curl -X POST 'https://verifyUser.abc.com/api/v1/verification' \
    -H 'secret: secret' \
    -H 'email: [email protected]' \
    -H 'accept: application/json, text/plain, */*' \
    -H 'authorizationtoken: bearer' \
    -F 'referenceFilePath= Add file path' \
    --compressed

This happens because firewall blocks the database connection.

Disable the firewall and then try running the program again. It worked for me... :D

It is easy to convert your OrderedDict to a regular Dict like this:

dict(OrderedDict([('method', 'constant'), ('data', '1.225')]))

If you have to store it as a string in your database, using JSON is the way to go. That is also quite simple, and you don't even have to worry about converting to a regular dict:

import json
d = OrderedDict([('method', 'constant'), ('data', '1.225')])
dString = json.dumps(d)

Or dump the data directly to a file:

with open('outFile.txt','w') as o:
    json.dump(d, o)

According to section 2.2 of the manual, you can use the Escape key pressed twice in place of the CTRL key. This allowed me to use Nano's key combination for GO TO LINE when running Nano on a Jupyter/ JupyterHub and accessing through my browser. The normal key combination was getting 'swallowed' as the manual warns about can more often happen with the ALT key on some systems, and which can be replaced by one press of the ESCAPE key.
So for jump to line it was ESCAPE pressed twice, followed by shift key + dash key.

Darren Davies is partially correct in saying that you should use a salt - there are several issues with his claim that MD5 is insecure.

You've said that you have to insert the password using an Md5 hash, but that doesn't really tell us why. Is it because that's the format used when validatinb the password? Do you have control over the code which validates the password?

The thing about using a salt is that it avoids the problem where 2 users have the same password - they'll also have the same hash - not a desirable outcome. By using a diferent salt for each password then this does not arise (with very large volumes of data there is still a risk of collisions arising from 2 different passwords - but we'll ignore that for now).

So you can aither generate a random value for the salt and store that in the record too, or you could use some of the data you already hold - such as the username:

$query="INSERT INTO ptb_users (id,
        user_id,
        first_name,
        last_name,
        email )
        VALUES('NULL',
        'NULL',
        '".$firstname."',
        '".$lastname."',
        '".$email."',
        MD5('"$user_id.$password."')
        )";

(I am assuming that you've properly escaped all those strings earlier in your code)

In a pure object-oriented world getters and setters is a terrible anti-pattern. Read this article: Getters/Setters. Evil. Period. In a nutshell, they encourage programmers to think about objects as of data structures, and this type of thinking is pure procedural (like in COBOL or C). In an object-oriented language there are no data structures, but only objects that expose behavior (not attributes/properties!)

You may find more about them in Section 3.5 of Elegant Objects (my book about object-oriented programming).

OpenURI is the best; it's as simple as

require 'open-uri'
response = open('http://example.com').read

This works for me.

A Seq is an Iterable that has a defined order of elements. Sequences provide a method apply() for indexing, ranging from 0 up to the length of the sequence. Seq has many subclasses including Queue, Range, List, Stack, and LinkedList.

A List is a Seq that is implemented as an immutable linked list. It's best used in cases with last-in first-out (LIFO) access patterns.

Old question, be here's what I ended up using Java Source Attatcher plugin: http://marketplace.eclipse.org/content/java-source-attacher#.U85j4rF-N7s

It can provide source for different opensource projects. One weird thing thou, if you have libraries under libs folder, you cannot attach from there, but you need to attach source clicking on jar displayed under "Libraries from external".

std::vector uses the heap. Geez, what a waste that would be just for the sake of a const sanity-check. The point of std::vector is dynamic growth at run-time, not any old syntax checking that should be done at compile-time. If you're not going to grow then create a class to wrap a normal array.

#include <stdio.h>


template <class Type, size_t MaxLength>
class ConstFixedSizeArrayFiller {
private:
    size_t length;

public:
    ConstFixedSizeArrayFiller() : length(0) {
    }

    virtual ~ConstFixedSizeArrayFiller() {
    }

    virtual void Fill(Type *array) = 0;

protected:
    void add_element(Type *array, const Type & element)
    {
        if(length >= MaxLength) {
            // todo: throw more appropriate out-of-bounds exception
            throw 0;
        }
        array[length] = element;
        length++;
    }
};


template <class Type, size_t Length>
class ConstFixedSizeArray {
private:
    Type array[Length];

public:
    explicit ConstFixedSizeArray(
        ConstFixedSizeArrayFiller<Type, Length> & filler
    ) {
        filler.Fill(array);
    }

    const Type *Array() const {
        return array;
    }

    size_t ArrayLength() const {
        return Length;
    }
};


class a {
private:
    class b_filler : public ConstFixedSizeArrayFiller<int, 2> {
    public:
        virtual ~b_filler() {
        }

        virtual void Fill(int *array) {
            add_element(array, 87);
            add_element(array, 96);
        }
    };

    const ConstFixedSizeArray<int, 2> b;

public:
    a(void) : b(b_filler()) {
    }

    void print_items() {
        size_t i;
        for(i = 0; i < b.ArrayLength(); i++)
        {
            printf("%d\n", b.Array()[i]);
        }
    }
};


int main()
{
    a x;
    x.print_items();
    return 0;
}

ConstFixedSizeArrayFiller and ConstFixedSizeArray are reusable.

The first allows run-time bounds checking while initializing the array (same as a vector might), which can later become const after this initialization.

The second allows the array to be allocated inside another object, which could be on the heap or simply the stack if that's where the object is. There's no waste of time allocating from the heap. It also performs compile-time const checking on the array.

b_filler is a tiny private class to provide the initialization values. The size of the array is checked at compile-time with the template arguments, so there's no chance of going out of bounds.

I'm sure there are more exotic ways to modify this. This is an initial stab. I think you can pretty much make up for any of the compiler's shortcoming with classes.

brew switch openssl 1.0.2t

catalina this is ok.

Suppose you bound your combobox to a List<Person>

List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});

cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;

At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource

pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;

Of course this means that you need to add a checking code when you try to use the info from the combobox

if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
    MessageBox.Show("Please select a person name");
else
    ...... 

The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection

In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to

DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";    
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);

If you are not coding a web application, make sure your class in which @Autowiring is done is a spring bean. Typically, spring container won't be aware of the class which we might think of as a spring bean. We have to tell the Spring container about our spring classes.

This can be achieved by configuring in appln-contxt or the better way is to annotate class as @Component and please do not create the annotated class using new operator. Make sure you get it from Appln-context as below.

@Component
public class MyDemo {


    @Autowired
    private MyService  myService; 

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
            System.out.println("test");
            ApplicationContext ctx=new ClassPathXmlApplicationContext("spring.xml");
            System.out.println("ctx>>"+ctx);

            Customer c1=null;
            MyDemo myDemo=ctx.getBean(MyDemo.class);
            System.out.println(myDemo);
            myDemo.callService(ctx);


    }

    public void callService(ApplicationContext ctx) {
        // TODO Auto-generated method stub
        System.out.println("---callService---");
        System.out.println(myService);
        myService.callMydao();

    }

}

Do you want to sort all files in a folder and subfolder overriding them?

Use this:

find . -type f -exec sort {} -o {} \;

Simple answer

If you want to match single character, put it inside those brackets [ ]

Examples

• match + ...... [+] or +
• match a ...... a
• match & ...... &

...and so on. You can check your regular expresion online on this site: https://regex101.com/

The IPv6 addresses for fields like RemoteAddr from http.Request are formatted as "[::1]:53343"

So net.SplitHostPort works great:

package main

    import (
        "fmt"
        "net"
    )

    func main() {
        host1, port, err := net.SplitHostPort("127.0.0.1:5432")
        fmt.Println(host1, port, err)

        host2, port, err := net.SplitHostPort("[::1]:2345")
        fmt.Println(host2, port, err)

        host3, port, err := net.SplitHostPort("localhost:1234")
        fmt.Println(host3, port, err)
    }

Output is:

127.0.0.1 5432 <nil>
::1 2345 <nil>
localhost 1234 <nil>

From the docs:

_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.

So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.

Edit: Further reading led me here:

http://www.analyticsmarket.com/blog/edit-ecommerce-data

Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.

In case if you are getting an error as "unterminated string constant", use the following razor syntax :

Marek Sebera's is great most of the time, but if you're like me and find that you need to check the iOS version frequently, you don't want to constantly run a macro in memory because you'll experience a very slight slowdown, especially on older devices.

Instead, you want to compute the iOS version as a float once and store it somewhere. In my case, I have a GlobalVariables singleton class that I use to check the iOS version in my code using code like this:

if ([GlobalVariables sharedVariables].iOSVersion >= 6.0f) {
    // do something if iOS is 6.0 or greater
}

To enable this functionality in your app, use this code (for iOS 5+ using ARC):

GlobalVariables.h:

@interface GlobalVariables : NSObject

@property (nonatomic) CGFloat iOSVersion;

    + (GlobalVariables *)sharedVariables;

@end

GlobalVariables.m:

@implementation GlobalVariables

@synthesize iOSVersion;

+ (GlobalVariables *)sharedVariables {
    // set up the global variables as a static object
    static GlobalVariables *globalVariables = nil;
    // check if global variables exist
    if (globalVariables == nil) {
        // if no, create the global variables class
        globalVariables = [[GlobalVariables alloc] init];
        // get system version
        NSString *systemVersion = [[UIDevice currentDevice] systemVersion];
        // separate system version by periods
        NSArray *systemVersionComponents = [systemVersion componentsSeparatedByString:@"."];
        // set ios version
        globalVariables.iOSVersion = [[NSString stringWithFormat:@"%01d.%02d%02d", \
                                       systemVersionComponents.count < 1 ? 0 : \
                                       [[systemVersionComponents objectAtIndex:0] integerValue], \
                                       systemVersionComponents.count < 2 ? 0 : \
                                       [[systemVersionComponents objectAtIndex:1] integerValue], \
                                       systemVersionComponents.count < 3 ? 0 : \
                                       [[systemVersionComponents objectAtIndex:2] integerValue] \
                                       ] floatValue];
    }
    // return singleton instance
    return globalVariables;
}

@end

Now you're able to easily check the iOS version without running macros constantly. Note in particular how I converted the [[UIDevice currentDevice] systemVersion] NSString to a CGFloat that is constantly accessible without using any of the improper methods many have already pointed out on this page. My approach assumes the version string is in the format n.nn.nn (allowing for later bits to be missing) and works for iOS5+. In testing, this approach runs much faster than constantly running the macro.

Hope this helps anyone experiencing the issue I had!

If you get the object after creation (for instance after "seasonal_decompose"), you can always access and edit the properties of the plot; for instance, changing the color of the first subplot from blue to black:

plt.axes[0].get_lines()[0].set_color('black')

Make sure the below is implemented For in-app reviews:

implementation 'com.google.android.play:core:1.8.0'

OnCreate

public void RateApp(Context mContext) {
    try {
        ReviewManager manager = ReviewManagerFactory.create(mContext);
        manager.requestReviewFlow().addOnCompleteListener(new OnCompleteListener<ReviewInfo>() {
            @Override
            public void onComplete(@NonNull Task<ReviewInfo> task) {
                if(task.isSuccessful()){
                    ReviewInfo reviewInfo = task.getResult();
                    manager.launchReviewFlow((Activity) mContext, reviewInfo).addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(Exception e) {
                            Toast.makeText(mContext, "Rating Failed", Toast.LENGTH_SHORT).show();
                        }
                    }).addOnCompleteListener(new OnCompleteListener<Void>() {
                        @Override
                        public void onComplete(@NonNull Task<Void> task) {
                            Toast.makeText(mContext, "Review Completed, Thank You!", Toast.LENGTH_SHORT).show();
                        }
                    });

The following was all done in cygwin on a Windows XP box.

This will get your IP address. Note that there are backquotes around the hostname command, not single quotes.

ping -n 1 `hostname` | grep "Reply from " | cut -f 3 -d " " | cut -f 1 -d ":"

This will get your subnet.

ping -n 1 `hostname` | grep "Reply from " | cut -f 3 -d " " | cut -f "1 2 3" -d "."

The following will list all hosts on your local network (put it into a script called "netmap"). I had taken the subnet line above and put it into an executable called "getsubnet", which I then called from the following script.

MINADDR=0
MAXADDR=255
SUBNET=`getsubnet`

hostcnt=0

echo Pinging all addresses in ${SUBNET}.${MINADDR}-${MAXADDR}

for i in `seq $MINADDR $MAXADDR`; do
addr=${SUBNET}.$i
ping -n 1 -w 0 $addr > /dev/null

if [ $? -ne 1 ]    
then    
echo $addr UP    
hostcnt=$((hostcnt+1))    
fi

done

echo Found $hostcnt hosts on subnet ${SUBNET}.${MINADDR}-${MAXADDR}

You can use this to copy directory overwriting existing files:

import shutil
shutil.copytree("src", "dst", dirs_exist_ok=True)

dirs_exist_ok argument was added in Python 3.8.

See docs: https://docs.python.org/3/library/shutil.html#shutil.copytree

I've written a library that helps do precisely this. It allows search by object simply by initializing only the fields you want to filter by: https://github.com/kg6zvp/GenericEntityEJB

Correcting Kooilnc's solution:

String.prototype.trunc = String.prototype.trunc ||
  function(n){
      return this.length>n ? this.substr(0,n-1)+'…' : this.toString();
  };

This returns the string value instead of the String object if it doesn't need to be truncated.

The pip wheel contains the python version in its name (cp34-cp34m). If you download the whl file and rename it to say py3-none or instead, it should work. Can you try that?

The installation won't work for anaconda users that choose python 3 support because the installation procedure is asking to create a python 3.5 environment and the file is currently called cp34-cp34m. So renaming it would do the job for now.

sudo pip3 install --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.7.0-cp34-cp34m-linux_x86_64.whl

This will produced the exact error message you got above. However, when you will downloaded the file yourself and rename it to "tensorflow-0.7.0-py3-none-linux_x86_64.whl", then execute the command again with changed filename, it should work fine.

don't use -notLike, -notMatch with Regular-Expression works in one line:

Your question has 2 tasks to be performed. First to extract the Email attachments to a folder and saving or renaming it with a specific name.

If your search can be split to 2 searches you will get more hits. I could refer one page that explains how to save the attachment to a system folder <Link for the page to save attachments to a folder>.

Please post any page or code if you have found to save the attachment with specific name.

Implementation 1 is the perp dot product of the two vectors. The best reference I know of for 2D graphics is the excellent Graphics Gems series. If you're doing scratch 2D work, it's really important to have these books. Volume IV has an article called "The Pleasures of Perp Dot Products" that goes over a lot of uses for it.

One major use of perp dot product is to get the scaled sin of the angle between the two vectors, just like the dot product returns the scaled cos of the angle. Of course you can use dot product and perp dot product together to determine the angle between two vectors.

Here is a post on it and here is the Wolfram Math World article.

I found the answer :)

Use JsonPath or XmlPath (in case you have XML) to get data from the response body.

In my case:

JsonPath jsonPath = new JsonPath(responseBody);
int user_id = jsonPath.getInt("user_id");

Signed variables, such as signed integers will allow you to represent numbers both in the positive and negative ranges.

Unsigned variables, such as unsigned integers, will only allow you to represent numbers in the positive and zero.

Unsigned and signed variables of the same type (such as int and byte) both have the same range (range of 65,536 and 256 numbers, respectively), but unsigned can represent a larger magnitude number than the corresponding signed variable.

For example, an unsigned byte can represent values from 0 to 255, while signed byte can represent -128 to 127.

Wikipedia page on Signed number representations explains the difference in the representation at the bit level, and the Integer (computer science) page provides a table of ranges for each signed/unsigned integer type.

In your action method, return Json(object) to return JSON to your page.

public ActionResult SomeActionMethod() {
  return Json(new {foo="bar", baz="Blech"});
}

Then just call the action method using Ajax. You could use one of the helper methods from the ViewPage such as

<%= Ajax.ActionLink("SomeActionMethod", new AjaxOptions {OnSuccess="somemethod"}) %>

SomeMethod would be a javascript method that then evaluates the Json object returned.

If you want to return a plain string, you can just use the ContentResult:

public ActionResult SomeActionMethod() {
    return Content("hello world!");
}

ContentResult by default returns a text/plain as its contentType.
This is overloadable so you can also do:

return Content("<xml>This is poorly formatted xml.</xml>", "text/xml");

Working solution.

<html>
          <head>
            <style type="text/css">
                html
                {
                    width: 100%;
                    height: 100%;
                }

                body
                {
                    display: flex;
                    justify-content: center;
                    align-items: center;
                }
            </style>
        </head>

        <body>
            Center aligned text.(horizontal and vertical side)
        </body>
</html>

You can use a regular expression that matches zeroes at the beginning of the string:

s = s.replace(/^0+/, '');

Do you have Egit installed yet? If not, go to Window->Preferences->Install/Updates->Available Software Sites. Click on add and paste this link http://download.eclipse.org/egit/updates

For Name, you can just put "EGit". After you have EGit installed, follow this tutorial. It helped me a lot!

In a similar use case, this worked for me...

<button onclick="window.open('https://www.w3.org/', '_blank');">  My Button </button>

After trying a number of suggested solutions without success I just rebooted my PC. After that the problem didn't occur anymore.

A minimalist example to get you started in Visual Studio:

1.Download and unzip Boost from here.

2.Create a Visual Studio empty project, using an example boost library that does not require separate compilation:

#include <iostream>
#include <boost/format.hpp>

using namespace std;  
using namespace boost;  

int main()  
{  
    unsigned int arr[5] = { 0x05, 0x04, 0xAA, 0x0F, 0x0D };  

    cout << format("%02X-%02X-%02X-%02X-%02X")  
            % arr[0]  
            % arr[1]  
            % arr[2]  
            % arr[3]  
            % arr[4]  
         << endl;  
}  

3.In your Visual Studio project properties set the Additional Include Directories:

For a very simple example:

If you don't want to use the entire boost library, just a subset:

In case someone else ends up here struggling to customize admin form Many2Many saving behaviour, you can't call self.instance.my_m2m.add(obj) in your ModelForm.save override, as ModelForm.save later populates your m2m from self.cleaned_data['my_m2m'] which overwrites your changes. Instead call:

my_m2ms = list(self.cleaned_data['my_m2ms'])
my_m2ms.extend(my_custom_new_m2ms)
self.cleaned_data['my_m2ms'] = my_m2ms

(It is fine to convert the incoming QuerySet to a list - the ManyToManyField does that anyway.)

MySQL Manual - slow-query-log-file

This claims that you can run the following to set the slow-log file (5.1.6 onwards):

set global slow_query_log_file = 'path';

The variable slow_query_log just controls whether it is enabled or not.

this happened to me when using JUnit + rest assured + hamcrest, in this case, dont add junit to build path, if you have the maven project, this resolved me, below is the pom.xml

You have the wrong table set on the command. You should use the following on your setup:

ALTER TABLE scode_tracker.ap_visits ENGINE=MyISAM;

This CSS effectively hides the spin-button for webkit browsers (have tested it in Chrome 7.0.517.44 and Safari Version 5.0.2 (6533.18.5)):

input::-webkit-outer-spin-button,_x000D_
input::-webkit-inner-spin-button {_x000D_
    /* display: none; <- Crashes Chrome on hover */_x000D_
    -webkit-appearance: none;_x000D_
    margin: 0; /* <-- Apparently some margin are still there even though it's hidden */_x000D_
}_x000D_
_x000D_
input[type=number] {_x000D_
    -moz-appearance:textfield; /* Firefox */_x000D_
}

<input type="number" step="0.01" />

You can always use the inspector (webkit, possibly Firebug for Firefox) to look for matched CSS properties for the elements you are interested in, look for Pseudo elements. This image shows results for an input element type="number":

You can also use glob for this:

$dirname = "media/images/iconized/";
$images = glob($dirname."*.png");

foreach($images as $image) {
    echo '<img src="'.$image.'" /><br />';
}

You can remove the entire line below:

 .map((res: Response) => res.json());

No need to use the map method at all.

I had a similar problem. The version of bootstrap.js that visual studio seems to be hosed. I just pointed to this URL instead:

try this :

driver = webdriver.Chrome(ChromeDriverManager().install())

raise ValueError('could not find %c in %s' % (ch,str))

I've had this problem before. Figured out I had another application using the same port (3000).

Easy way to find this out:

In the terminal, type netstat -a -p TCP -n | grep 3000 (substitute the port you're using for the '3000'). If there is more than one listening, something else is already occupying that port. You should stop that process or change the port for your new process.

This answer is for comparing two solutions, not a suggested solution.

Instead of creating another list as other answers suggested, you can used a for loop using the dictionary Count for the loop stop condition and Keys.ElementAt(i) to get the key.

for (int i = 0; i < dictionary.Count; i++)
{
    dictionary[dictionary.Keys.ElementAt(i)] = 0;
}

At firs I thought this would be more efficient because we do not need to create a key list. After running a test I found that the for loop solution is much less efficient. The reason is because ElementAt is O(n) on the dictionary.Keys property, it searches from the beginning of the collection until it gets to the nth item.

Test:

int iterations = 10;
int dictionarySize = 10000;
Stopwatch sw = new Stopwatch();

Console.WriteLine("Creating dictionary...");
Dictionary<string, int> dictionary = new Dictionary<string, int>(dictionarySize);
for (int i = 0; i < dictionarySize; i++)
{
    dictionary.Add(i.ToString(), i);
}
Console.WriteLine("Done");

Console.WriteLine("Starting tests...");

// for loop test
sw.Restart();
for (int i = 0; i < iterations; i++)
{
    for (int j = 0; j < dictionary.Count; j++)
    {
        dictionary[dictionary.Keys.ElementAt(j)] = 3;
    }
}
sw.Stop();
Console.WriteLine($"for loop Test:     {sw.ElapsedMilliseconds} ms");

// foreach loop test
sw.Restart();
for (int i = 0; i < iterations; i++)
{
    foreach (string key in dictionary.Keys.ToList())
    {
        dictionary[key] = 3;
    }
}
sw.Stop();
Console.WriteLine($"foreach loop Test: {sw.ElapsedMilliseconds} ms");

Console.WriteLine("Done");

Results:

Creating dictionary...
Done
Starting tests...
for loop Test:     2367 ms
foreach loop Test: 3 ms
Done

First check whether the file exists in SDCard. If the file doesnot exists in SDcard then you can set image using setImageResource() methodand passing default image from drawable folder

Sample Code

File imageFile = new File(absolutepathOfImage);//absolutepathOfImage is absolute path of image including its name
        if(!imageFile.exists()){//file doesnot exist in SDCard

        imageview.setImageResource(R.drawable.defaultImage);//set default image from drawable folder
        }

There are three "default" encodings:

• file.encoding:
  System.getProperty("file.encoding")

• java.nio.Charset:
  Charset.defaultCharset()

• And the encoding of the InputStreamReader:
  InputStreamReader.getEncoding()

You can read more about it on this page.

event.preventDefault()

Doesn't work in all browsers. Instead you could return false in OnClick event.

onClick="toggle_it('tr1');toggle_it('tr2'); return false;">

Not sure if this is the best way, but I tested in IE, FF and Chrome and its working fine.

If you're attempting to get an element you can use Vue.util.query which is really just a wrapper around document.querySelector but at 14 characters vs 22 characters (respectively) it is technically shorter. It also has some error handling in case the element you're searching for doesn't exist.

There isn't any official documentation on Vue.util, but this is the entire source of the function:

function query(el) {
  if (typeof el === 'string') {
    var selector = el;
    el = document.querySelector(el);
    if (!el) {
      ({}).NODE_ENV !== 'production' && warn('Cannot find element: ' + selector);
    }
  }
  return el;
}

Xerces-based tools will emit the following error

The processing instruction target matching "[xX][mM][lL]" is not allowed.

when an XML declaration is encountered anywhere other than at the top of an XML file.

This is a valid diagnostic message; other XML parsers should issue a similar error message in this situation.

To correct the problem, check the following possibilities:

1. Some blank space or other visible content exists before the <?xml ?> declaration.

   Resolution: remove blank space or any other visible content before the XML declaration.

2. Some invisible content exists before the <?xml ?> declaration. Most commonly this is a Byte Order Mark (BOM).

   Resolution: Remove the BOM using techniques such as those suggested by the W3C page on the BOM in HTML.

3. A stray <?xml ?> declaration exists within the XML content. This can happen when XML files are combined programmatically or via cut-and-paste. There can only be one <?xml ?> declaration in an XML file, and it can only be at the top.

   Resolution: Search for <?xml in a case-insensitive manner, and remove all but the top XML declaration from the file.

you can use mongo query like this yearMonthDayhms: { $dateToString: { format: "%Y-%m-%d-%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}

HourMinute: { $dateToString: { format: "%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}

I would just use get_the_post_thumbnail_url() instead of get_the_post_thumbnail()

<img src="<?php echo get_the_post_thumbnail_url($loop->post->ID); ?>" class="img-responsive" alt=""/>

try adding this in AppDelegate applicationWillEnterForeground.

func applicationWillEnterForeground(_ application: UIApplication) {        
    // makes viewWillAppear run

    self.window?.rootViewController?.endAppearanceTransition()

    mProgress = (ProgressBar) findViewById(R.id.pb);

    foryou.setOnClickListener(this);
    following.setOnClickListener(this);
    popular.setOnClickListener(this);
    watching.setOnClickListener(this);

            break;
        case R.id.btn_following:
            following.setPaintFlags(following.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_popular:
            popular.setPaintFlags(popular.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_continuewatching:
            watching.setPaintFlags(watching.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_5:
            // foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        default:
            foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

    }
}

    </configuration>
</plugin>

Removing the following entries fixed the problem

<index>true</index>
<manifest>
    <addClasspath>true</addClasspath>
</manifest>

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

The complete solution including email addresses in path names for spring 4.2 is

<bean id="contentNegotiationManager"
    class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
    <property name="favorPathExtension" value="false" />
    <property name="favorParameter" value="true" />
    <property name="mediaTypes">
        <value>
            json=application/json
            xml=application/xml
        </value>
    </property>
</bean>
<mvc:annotation-driven
    content-negotiation-manager="contentNegotiationManager">
    <mvc:path-matching suffix-pattern="false" registered-suffixes-only="true" />
</mvc:annotation-driven>

Add this to the application-xml

or you can set pointer-events:none to your a element and pointer-event:all to your a:before element, and then add hover CSS to a element

a{
    pointer-events:none;
}
a:before{
    pointer-events:all
}
a:hover:before{
    background:blue;
}

Dear olga is clear what the message says. Turn off the custom errors to see the details about this error for fix it, and then you close them back. So add mode="off" as:

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

Relative answer: Deploying website: 500 - Internal server error

By the way: The error message declare that the web.config is not the one you type it here. Maybe you have forget to upload your web.config ? And remember to close the debug flag on the web.config that you use for online pages.

If you want Console.WriteLine("example text") output to show up in the Debug Output window, temporarily change the Output type of your Application from Console Application to Windows Application.

From menus choose Project + Properties, and navigate to Output type: drop down, change to Windows Application then run your application

Of course you should change it back for building a console application intended to run outside of the IDE.

(tested with Visual Studio 2008 and 2010, expect it should work in latter versions too)

I recommend using passthru and handling the output buffer directly:

ob_start();
passthru('/usr/bin/python2.7 /srv/http/assets/py/switch.py arg1 arg2');
$output = ob_get_clean(); 

Using the index:

df[1:4,]

Where the values in the parentheses can be interpreted as either logical, numeric, or character (matching the respective names):

df[row.index, column.index]

Read help(`[`) for more detail on this subject, and also read about index matrices in the Introduction to R.

When creating a PWA, a service worker used on an non https server also generates this error.

A unique approach I haven't seen anyone mention!

The only way I was able to get all the customisation I wanted was to use an after_validation callback to allow me to manipulate the error message.

1. Allow the validation message to be created as normal, you don't need to try and change it in the validation helper.

2. create an after_validation callback that will replace that validation message in the back-end before it gets to the view.

3. In the after_validation method you can do anything you want with the validation message, just like a normal string! You can even use dynamic values and insert them into the validation message.

#this could be any validation
validates_presence_of :song_rep_xyz, :message => "whatever you want - who cares - we will replace you later"

after_validation :replace_validation_message

def replace_validation_message
    custom_value = #any value you would like
    errors.messages[:name_of_the_attribute] = ["^This is the replacement message where 
    you can now add your own dynamic values!!! #{custom_value}"]
end

The after_validation method will have far greater scope than the built in rails validation helper, so you will be able to access the object you are validating like you are trying to do with object.file_name. Which does not work in the validation helper where you are trying to call it.

Note: we use the ^ to get rid of the attribute name at the beginning of the validation as @Rystraum pointed out referencing this gem

Could append a new stylesheet to head within $routeProvider. For simplicity am using a string but could create new link element also, or create a service for stylesheets

/* check if already exists first - note ID used on link element*/
/* could also track within scope object*/
if( !angular.element('link#myViewName').length){
    angular.element('head').append('<link id="myViewName" href="myViewName.css" rel="stylesheet">');
}

Biggest benefit of prelaoding in page is any background images will already exist, and less lieklyhood of FOUC

Is there a way to set the session timeout programatically

There are basically three ways to set the session timeout value:

• by using the session-timeout in the standard web.xml file ~or~
• in the absence of this element, by getting the server's default session-timeout value (and thus configuring it at the server level) ~or~
• programmatically by using the HttpSession. setMaxInactiveInterval(int seconds) method in your Servlet or JSP.

But note that the later option sets the timeout value for the current session, this is not a global setting.

I had a similar issue as you, although I was trying to use start to open Chrome and using the file path. I used only start chrome.exe and it opened just fine. You may want to try to do the same with exe file. Using the file path may be unnecessary.

Here are some examples (using the file name you gave in a comment on another answer):

• Instead of C:\Program^ Files\temp.exe you can try temp.exe.

• Instead of start C:\Program^ Files\temp.exe you can try start temp.exe

In case somebody needs to append the output and not overriding, it is possible to use "-a" or "--append" option of "tee" command :

ls 2>&1 | tee -a /tmp/ls.txt
ls 2>&1 | tee --append /tmp/ls.txt

Sets are faster, morover you get more functions with sets, such as lets say you have two sets :

set1 = {"Harry Potter", "James Bond", "Iron Man"}
set2 = {"Captain America", "Black Widow", "Hulk", "Harry Potter", "James Bond"}

We can easily join two sets:

set3 = set1.union(set2)

Find out what is common in both:

set3 = set1.intersection(set2)

Find out what is different in both:

set3 = set1.difference(set2)

And much more! Just try them out, they are fun! Moreover if you have to work on the different values within 2 list or common values within 2 lists, I prefer to convert your lists to sets, and many programmers do in that way. Hope it helps you :-)

Here is my answer that works just fine...

You should be able to get current Activity in this way... If you structure your app with a few Activities with many fragments and you want to keep track of what is your current Activity, it would take a lot of work though. My senario was I do have one Activity with multiple Fragments. So I can keep track of Current Activity through Application Object, which can store all of the current state of Global variables.

Here is a way. When you start your Activity, you store that Activity by Application.setCurrentActivity(getIntent()); This Application will store it. On your service class, you can simply do like Intent currentIntent = Application.getCurrentActivity(); getApplication().startActivity(currentIntent);

This was what I did to solve my related problem

interface Map {
  [key: string]: string | undefined
}

const HUMAN_MAP: Map = {
  draft: "Draft",
}

export const human = (str: string) => HUMAN_MAP[str] || str

If you're not completely attached to using "from" and "to" as your option names, it's fairly easy to implement this using getopts:

while getopts f:t: opts; do
   case ${opts} in
      f) FROM_VAL=${OPTARG} ;;
      t) TO_VAL=${OPTARG} ;;
   esac
done

getopts is a program that processes command line arguments and conveniently parses them for you.

f:t: specifies that you're expecting 2 parameters that contain values (indicated by the colon). Something like f:t:v says that -v will only be interpreted as a flag.

opts is where the current parameter is stored. The case statement is where you will process this.

${OPTARG} contains the value following the parameter. ${FROM_VAL} for example will get the value /home/kristoffer/test.png if you ran your script like:

ocrscript.sh -f /home/kristoffer/test.png -t /home/kristoffer/test.txt

As the others are suggesting, if this is your first time writing bash scripts you should really read up on some basics. This was just a quick tutorial on how getopts works.

String.prototype.padZero= function(len, c){
    var s= this, c= c || '0';
    while(s.length< len) s= c+ s;
    return s;
}

dispite the name, you can left-pad with any character, including a space. I never had a use for right side padding, but that would be easy enough.

The only way to change the $type of the data is to perform an update on the data where the data has the correct type.

In this case, it looks like you're trying to change the $type from 1 (double) to 2 (string).

So simply load the document from the DB, perform the cast (new String(x)) and then save the document again.

If you need to do this programmatically and entirely from the shell, you can use the find(...).forEach(function(x) {}) syntax.

In response to the second comment below. Change the field bad from a number to a string in collection foo.

db.foo.find( { 'bad' : { $type : 1 } } ).forEach( function (x) {   
  x.bad = new String(x.bad); // convert field to string
  db.foo.save(x);
});

Using Ajax in javascript

here is the explained code in Github repo https://github.com/dupinder/staticHTML-Include

basic idea is:

index.html

<!DOCTYPE html>
<html>
<head>
    <meta charset='utf-8'>
    <meta http-equiv='X-UA-Compatible' content='IE=edge'>
    <title>Page Title</title>
    <meta name='viewport' content='width=device-width, initial-scale=1'>
    <script src='main.js'></script>


</head>
<body>
    <header></header>

    <footer></footer>
</body>
</html>

main.js

fetch("./header.html")
  .then(response => {
    return response.text()
  })
  .then(data => {
    document.querySelector("header").innerHTML = data;
  });

fetch("./footer.html")
  .then(response => {
    return response.text()
  })
  .then(data => {
    document.querySelector("footer").innerHTML = data;
  });

Try that:

$createdAt = Carbon::parse(date_format($item['created_at'],'d/m/Y H:i:s');
$createdAt= $createdAt->format('M d Y');

I second Harmen's div suggestion. Alternatively, you can wrap the table in a form, and use javascript to capture the row focus and adjust the form action via javascript before submit.

You can see that your locks are pretty much working as you are using them, if you slow down the process and make them block a bit more. You had the right idea, where you surround critical pieces of code with the lock. Here is a small adjustment to your example to show you how each waits on the other to release the lock.

import threading
import time
import inspect

class Thread(threading.Thread):
    def __init__(self, t, *args):
        threading.Thread.__init__(self, target=t, args=args)
        self.start()

count = 0
lock = threading.Lock()

def incre():
    global count
    caller = inspect.getouterframes(inspect.currentframe())[1][3]
    print "Inside %s()" % caller
    print "Acquiring lock"
    with lock:
        print "Lock Acquired"
        count += 1  
        time.sleep(2)  

def bye():
    while count < 5:
        incre()

def hello_there():
    while count < 5:
        incre()

def main():    
    hello = Thread(hello_there)
    goodbye = Thread(bye)


if __name__ == '__main__':
    main()

Sample output:

...
Inside hello_there()
Acquiring lock
Lock Acquired
Inside bye()
Acquiring lock
Lock Acquired
...

I've worked with a lot of CSV files in my time. I'd like to add the advice:

1 - Depending on the source (Excel, etc), commas or tabs may be embedded in a field. Usually, the rule is that they will be 'protected' because the field will be double-quote delimited, as in "Boston, MA 02346".

2 - Some sources will not double-quote delimit all text fields. Other sources will. Others will delimit all fields, even numerics.

3 - Fields containing double-quotes usually get the embedded double quotes doubled up (and the field itself delimited with double quotes, as in "George ""Babe"" Ruth".

4 - Some sources will embed CR/LFs (Excel is one of these!). Sometimes it'll be just a CR. The field will usually be double-quote delimited, but this situation is very difficult to handle.

If you are using Python, I would suggest by exploring the request object:

dir(request)

Since the object support the method dict:

request.__dict__

It can be printed or saved. I use it to log 404 codes in Flask:

@app.errorhandler(404)
def not_found(e):
    with open("./404.csv", "a") as f:
        f.write(f'{datetime.datetime.now()},{request.__dict__}\n')
    return send_file('static/images/Darknet-404-Page-Concept.png', mimetype='image/png')

Here is the same script as submitted by user l--''''''---------'''''''''''', but corrected to work on a case-sensitive SQL instance, and with some other minor improvements.

Try if that works

sc = spark.sparkContext

# Infer the schema, and register the DataFrame as a table.
schemaPeople = spark.createDataFrame(RddName)
schemaPeople.createOrReplaceTempView("RddName")

I made this for when doing aggregate functions and similar

per.fun <- function(x) {
    if(length(x)>1){
        denom <- length(x);
        num <- sum(x);
        percentage <- num/denom;
        percentage*100
        }
        else NA
    }

To add on to the other answers here, if you would like to create a new object of a third different type with a where clause (e.g. one that is not your Entity Framework object) you can do this:

public IEnumerable<ThirdNonEntityClass> demoMethod(IEnumerable<int> property1Values)
{
    using(var entityFrameworkObjectContext = new EntityFrameworkObjectContext )
    {
        var result = entityFrameworkObjectContext.SomeClass
            .Join(entityFrameworkObjectContext.SomeOtherClass,
                sc => sc.property1,
                soc => soc.property2,
                (sc, soc) => new {sc, soc})
            .Where(s => propertyValues.Any(pvals => pvals == es.sc.property1)
            .Select(s => new ThirdNonEntityClass 
            {
                dataValue1 = s.sc.dataValueA,
                dataValue2 = s.soc.dataValueB
            })
            .ToList();
    }

    return result;

}    

Pay special attention to the intermediate object that is created in the Where and Select clauses.

Note that here we also look for any joined objects that have a property1 that matches one of the ones in the input list.

I know this is a bit more complex than what the original asker was looking for, but hopefully it will help someone.

Keep the h2 at the top, then pull-left on the p and pull-right on the login-box

<div class='container'>
  <div class='hero-unit'>

    <h2>Welcome</h2>

    <div class="pull-left">
      <p>Please log in</p>
    </div>

    <div id='login-box' class='pull-right control-group'>
        <div class='clearfix'>
            <input type='text' placeholder='Username' />
        </div>
        <div class='clearfix'>
            <input type='password' placeholder='Password' />
        </div>
        <button type='button' class='btn btn-primary'>Log in</button>
    </div>

    <div class="clearfix"></div>

  </div>
</div>

the default vertical-align on floated boxes is baseline, so the "Please log in" exactly lines up with the "Username" (check by changing the pull-right to pull-left).

An instance variable is a variable that is a member of an instance of a class (i.e., associated with something created with a new), whereas a class variable is a member of the class itself.

Every instance of a class will have its own copy of an instance variable, whereas there is only one of each static (or class) variable, associated with the class itself.

What’s the difference between a class variable and an instance variable?

This test class illustrates the difference:

public class Test {
   
    public static String classVariable = "I am associated with the class";
    public String instanceVariable = "I am associated with the instance";
    
    public void setText(String string){
        this.instanceVariable = string;
    }
    
    public static void setClassText(String string){
        classVariable = string;
    }
    
    public static void main(String[] args) {
        Test test1 = new Test();
        Test test2 = new Test();
        
        // Change test1's instance variable
        test1.setText("Changed");
        System.out.println(test1.instanceVariable); // Prints "Changed"
        // test2 is unaffected
        System.out.println(test2.instanceVariable); // Prints "I am associated with the instance"
        
        // Change class variable (associated with the class itself)
        Test.setClassText("Changed class text");
        System.out.println(Test.classVariable); // Prints "Changed class text"
        
        // Can access static fields through an instance, but there still is only one
        // (not best practice to access static variables through instance)
        System.out.println(test1.classVariable); // Prints "Changed class text"
        System.out.println(test2.classVariable); // Prints "Changed class text"
    }
}

The javascript library sugar.js (http://sugarjs.com/) has functions to format dates

Example:

Date.create().format('{dd}/{MM}/{yyyy} {hh}:{mm}:{ss}.{fff}')

This topic shows up on the first page of my google result, so here's a little useful tip for new comers.

You could also dump the sql and gzip it in one line:

mysqldump -u [username] -p[password] [database_name] | gzip > [filename.sql.gz]

1. In your code, jQuery just looks for the first instance of an input with name q12_3, which in this case has a value of 1. You want an input with name q12_3 that is :checked.

$(function(){
    $("#submit").click(function() {     
        alert($("input[name=q12_3]:checked").val());
    });
});

2. Note that the above code is not the same as using .is(":checked"). jQuery's is() function returns a boolean (true or false) and not an element.
