To be totally exhaustive, things are different if you're using a JPA 1.0 or a JPA 2.0 implementation.

JPA 1.0

With JPA 1.0, you'd have to use EntityManager#getDelegate(). But keep in mind that the result of this method is implementation specific i.e. non portable from application server using Hibernate to the other. For example with JBoss you would do:

org.hibernate.Session session = (Session) manager.getDelegate();

But with GlassFish, you'd have to do:

org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession(); 

I agree, that's horrible, and the spec is to blame here (not clear enough).

JPA 2.0

With JPA 2.0, there is a new (and much better) EntityManager#unwrap(Class<T>) method that is to be preferred over EntityManager#getDelegate() for new applications.

So with Hibernate as JPA 2.0 implementation (see 3.15. Native Hibernate API), you would do:

Session session = entityManager.unwrap(Session.class);

What exactly do you want to know?

The shared library soname? That's part of the filename, libstdc++.so.6, or shown by readelf -d /usr/lib64/libstdc++.so.6 | grep soname.

The minor revision number? You should be able to get that by simply checking what the symlink points to:

$ ls -l  /usr/lib/libstdc++.so.6
lrwxrwxrwx. 1 root root 19 Mar 23 09:43 /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.16

That tells you it's 6.0.16, which is the 16th revision of the libstdc++.so.6 version, which corresponds to the GLIBCXX_3.4.16 symbol versions.

Or do you mean the release it comes from? It's part of GCC so it's the same version as GCC, so unless you've screwed up your system by installing unmatched versions of g++ and libstdc++.so you can get that from:

$ g++ -dumpversion
4.6.3

Or, on most distros, you can just ask the package manager. On my Fedora host that's

$ rpm -q libstdc++
libstdc++-4.6.3-2.fc16.x86_64
libstdc++-4.6.3-2.fc16.i686

As other answers have said, you can map releases to library versions by checking the ABI docs

This bug cost me 2 days. I checked my Server log, the Preflight Option request/response between browser Chrome/Edge and Server was ok. The main reason is that GET/POST/PUT/DELETE server response for XHTMLRequest must also have the following header:

access-control-allow-origin: origin  

"origin" is in the request header (Browser will add it to request for you). for example:

Origin: http://localhost:4221

you can add response header like the following to accept for all:

access-control-allow-origin: *  

or response header for a specific request like:

access-control-allow-origin: http://localhost:4221 

The message in browsers is not clear to understand: "...The requested resource"

note that: CORS works well for localhost. different port means different Domain. if you get error message, check the CORS config on the server side.

Update: This solution works and just a call to 'FB.logout()' doesn't work because browser wants a user interaction to actually call this function, so that it knows - it is a user not a script.

<a href="#" onclick="FB.logout();">Logout</a> 

This might be late, but I hope it helps someone who is looking for the answer.

You can use the following line to do that:

Server.TransferRequest(Request.Url.AbsolutePath, false);

Try to avoid using Response.Redirect as it increases the steps in the process. What it actually does is:

1. Sends back the page with redirection header
2. The Browser redirects to the destination URL.

As you can see, the same outcome takes 2 trips rather than 1 trip.

Actually there is no option to do that, if you want to uninstall packages from package.json simply do npm ls on the same directory that package.json relies and use npm uninstall <name> or npm rm <name> for the package you want to remove.

You could use this:

string path = @"c:\projects\roott\wsdlproj\devlop\beta2\text";
string lastDirectory = path.Split(new char[] { System.IO.Path.DirectorySeparatorChar }, StringSplitOptions.RemoveEmptyEntries).Last();

In Eclipse, go to File -> Switch Workspace, choose or create a new workspace.

PHP by itself has no SMS module or functions and doesn't allow you to send SMS.

SMS ( Short Messaging System) is a GSM technology an you need a GSM provider that will provide this service for you and may have an PHP API implementation for it.

Usually people in telecom business use Asterisk to handle calls and sms programming.

For temporary internal files their are 2 options

1.

File file; 
file = File.createTempFile(filename, null, this.getCacheDir());

2.

File file
file = new File(this.getCacheDir(), filename);

Both options adds files in the applications cache directory and thus can be cleared to make space as required but option 1 will add a random number on the end of the filename to keep files unique. It will also add a file extension which is .tmp by default, but it can be set to anything via the use of the 2nd parameter. The use of the random number means despite specifying a filename it doesn't stay the same as the number is added along with the suffix/file extension (.tmp by default) e.g you specify your filename as internal_file and comes out as internal_file1456345.tmp. Whereas you can specify the extension you can't specify the number that is added. You can however find the filename it generates via file.getName();, but you would need to store it somewhere so you can use it whenever you wanted for example to delete or read the file. Therefore for this reason I prefer the 2nd option as the filename you specify is the filename that is created.

As an ArrayList that line would be

import java.util.ArrayList;
...
ArrayList<Card> hand = new ArrayList<Card>();

To use the ArrayList you have do

hand.get(i); //gets the element at position i 
hand.add(obj); //adds the obj to the end of the list
hand.remove(i); //removes the element at position i
hand.add(i, obj); //adds the obj at the specified index
hand.set(i, obj); //overwrites the object at i with the new obj

Also read this http://docs.oracle.com/javase/6/docs/api/java/util/ArrayList.html

To pass a string to the view as the Model, you can do:

public ActionResult Index()
{
    string myString = "This is my string";
    return View((object)myString);
}

You must cast it to an object so that MVC doesn't try to load the string as the view name, but instead pass it as the model. You could also write:

return View("Index", myString);

.. which is a bit more verbose.

Then in your view, just type it as a string:

@model string

<p>Value: @Model</p>

Then you can manipulate Model how you want.

For accessing it from a Layout page, it might be better to create an HtmlExtension for this:

public static string GetThemePath(this HtmlHelper helper)
{
    return "/path-to-theme";
}

Then inside your layout page:

<p>Value: @Html.GetThemePath()</p>

Hopefully you can apply this to your own scenario.

Edit: explicit HtmlHelper code:

namespace <root app namespace>
{
    public static class Helpers
    {
        public static string GetThemePath(this HtmlHelper helper)
        {
            return System.Web.Hosting.HostingEnvironment.MapPath("~") + "/path-to-theme";
        }
    }
}

Then in your view:

@{
    var path = Html.GetThemePath();
    // .. do stuff
}

Or: <p>Path: @Html.GetThemePath()</p>

Edit 2:

As discussed, the Helper will work if you add a @using statement to the top of your view, with the namespace pointing to the one that your helper is in.

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

I had this problem. The solution was to allow node.js through the server's firewall.

This is for Visual Studio 2019, After trying a lot of suggestions that failed to work (including changing the port number etc) I solved my problem by deleting a file that was generated on my project's root folder called "debug". As soon as this file was deleted everything started working.

Disabling and Enabling All Foreign Keys

CREATE PROCEDURE pr_Disable_Triggers_v2
    @disable BIT = 1
AS
    DECLARE @sql VARCHAR(500)
        ,   @tableName VARCHAR(128)
        ,   @tableSchema VARCHAR(128)

    -- List of all tables
    DECLARE triggerCursor CURSOR FOR
        SELECT  t.TABLE_NAME AS TableName
            ,   t.TABLE_SCHEMA AS TableSchema
        FROM    INFORMATION_SCHEMA.TABLES t
        ORDER BY t.TABLE_NAME, t.TABLE_SCHEMA

    OPEN    triggerCursor
    FETCH NEXT FROM triggerCursor INTO @tableName, @tableSchema
    WHILE ( @@FETCH_STATUS = 0 )
    BEGIN

        SET @sql = 'ALTER TABLE ' + @tableSchema + '.[' + @tableName + '] '
        IF @disable = 1
            SET @sql = @sql + ' DISABLE TRIGGER ALL'
        ELSE
            SET @sql = @sql + ' ENABLE TRIGGER ALL'

        PRINT 'Executing Statement - ' + @sql
        EXECUTE ( @sql )

        FETCH NEXT FROM triggerCursor INTO @tableName, @tableSchema

    END

    CLOSE triggerCursor
    DEALLOCATE triggerCursor

First, the foreignKeyCursor cursor is declared as the SELECT statement that gathers the list of foreign keys and their table names. Next, the cursor is opened and the initial FETCH statement is executed. This FETCH statement will read the first row's data into the local variables @foreignKeyName and @tableName. When looping through a cursor, you can check the @@FETCH_STATUS for a value of 0, which indicates that the fetch was successful. This means the loop will continue to move forward so it can get each successive foreign key from the rowset. @@FETCH_STATUS is available to all cursors on the connection. So if you are looping through multiple cursors, it is important to check the value of @@FETCH_STATUS in the statement immediately following the FETCH statement. @@FETCH_STATUS will reflect the status for the most recent FETCH operation on the connection. Valid values for @@FETCH_STATUS are:

0 = FETCH was successful
-1 = FETCH was unsuccessful
-2 = the row that was fetched is missing

Inside the loop, the code builds the ALTER TABLE command differently depending on whether the intention is to disable or enable the foreign key constraint (using the CHECK or NOCHECK keyword). The statement is then printed as a message so its progress can be observed and then the statement is executed. Finally, when all rows have been iterated through, the stored procedure closes and deallocates the cursor.

see Disabling Constraints and Triggers from MSDN Magazine

Here:

function isweekend($year, $month, $day)
{
    $time = mktime(0, 0, 0, $month, $day, $year);
    $weekday = date('w', $time);
    return ($weekday == 0 || $weekday == 6);
}

some time joins on the table will be an overhead. lets say for OLAP. if i have two tables one is ORDERS table and other one is ORDER_DETAILS. For getting all the order details we have to join two tables this will make the query slower when no of rows in the tables increase lets say in millions or so.. left/right join is too slower than inner join. I Think if we add JSON string/Object in the respective ORDERS entry JOIN will be avoided. add report generation will be faster...

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

To get the output of ls, use stdout=subprocess.PIPE.

>>> proc = subprocess.Popen('ls', stdout=subprocess.PIPE)
>>> output = proc.stdout.read()
>>> print output
bar
baz
foo

The command cdrecord --help outputs to stderr, so you need to pipe that indstead. You should also break up the command into a list of tokens as I've done below, or the alternative is to pass the shell=True argument but this fires up a fully-blown shell which can be dangerous if you don't control the contents of the command string.

>>> proc = subprocess.Popen(['cdrecord', '--help'], stderr=subprocess.PIPE)
>>> output = proc.stderr.read()
>>> print output
Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

If you have a command that outputs to both stdout and stderr and you want to merge them, you can do that by piping stderr to stdout and then catching stdout.

subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

As mentioned by Chris Morgan, you should be using proc.communicate() instead of proc.read().

>>> proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> out, err = proc.communicate()
>>> print 'stdout:', out
stdout: 
>>> print 'stderr:', err
stderr:Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

This can be something to start with:

import configparser

config = configparser.ConfigParser()
config.read('FILE.INI')
print(config['DEFAULT']['path'])     # -> "/path/name/"
config['DEFAULT']['path'] = '/var/shared/'    # update
config['DEFAULT']['default_message'] = 'Hey! help me!!'   # create

with open('FILE.INI', 'w') as configfile:    # save
    config.write(configfile)

You can find more at the official configparser documentation.

values()

Returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterable.

values_list()

Returns a QuerySet that returns list of tuples, rather than model instances, when used as an iterable.

distinct()

distinct are used to eliminate the duplicate elements.

Example:

>>> list(Article.objects.values_list('id', flat=True)) # flat=True will remove the tuples and return the list   
[1, 2, 3, 4, 5, 6]

>>> list(Article.objects.values('id'))
[{'id':1}, {'id':2}, {'id':3}, {'id':4}, {'id':5}, {'id':6}]

Well to make the decimal into a percent you can do this,

float percentage = (correct * 100.0f) / questionNum;

Best description i've encounter so far is available on Oracle website.

Java SE's API provides the core functionality of the Java programming language. It defines everything from the basic types and objects of the Java programming language to high-level classes that are used for networking, security, database access, graphical user interface (GUI) development, and XML parsing.

The Java EE platform is built on top of the Java SE platform. The Java EE platform provides an API and runtime environment for developing and running large-scale, multi-tiered, scalable, reliable, and secure network applications.

If you consider developing application using for example Spring Framework you will use both API's and would have to learn key concept of JavaServer Pages and related technologies like for ex.: JSP, JPA, JDBC, Dependency Injection etc.

Perl solution which does not add leading or trailing whitespace:

perl -lane 'splice @F,0,3; print join " ",@F' file

The perl @F autosplit array starts at index 0 while awk fields start with $1

Perl solution for comma-delimited data:

perl -F, -lane 'splice @F,0,3; print join ",",@F' file

Python solution:

python -c "import sys;[sys.stdout.write(' '.join(line.split()[3:]) + '\n') for line in sys.stdin]" < file

You can simply export the table with a query clause using datapump and import it back with table_exists_action=replace clause. Its will drop and recreate your table and take very less time. Please read about it before implementing.

Set is a collection of un-ordered and unique elements. So, you can use set as below to get a unique list:

unique_list = list(set([u'nowplaying', u'PBS', u'PBS', u'nowplaying', u'job', u'debate', u'thenandnow']))

You could use the function trim

let str = ' Hello World ';

alert (str.trim());

All the front and back spaces around Hello World would be removed.

C++17 (All references are from the final working draft of CPP17 - n4659)

Insertion

Sequence Containers

• vector: The functions insert, emplace_back, emplace, push_back cause reallocation if the new size is greater than the old capacity. Reallocation invalidates all the references, pointers, and iterators referring to the elements in the sequence. If no reallocation happens, all the iterators and references before the insertion point remain valid. [26.3.11.5/1]
  With respect to the reserve function, reallocation invalidates all the references, pointers, and iterators referring to the elements in the sequence. No reallocation shall take place during insertions that happen after a call to reserve() until the time when an insertion would make the size of the vector greater than the value of capacity(). [26.3.11.3/6]

• deque: An insertion in the middle of the deque invalidates all the iterators and references to elements of the deque. An insertion at either end of the deque invalidates all the iterators to the deque, but has no effect on the validity of references to elements of the deque. [26.3.8.4/1]

• list: Does not affect the validity of iterators and references. If an exception is thrown there are no effects. [26.3.10.4/1].
  The insert, emplace_front, emplace_back, emplace, push_front, push_back functions are covered under this rule.

• forward_list: None of the overloads of insert_after shall affect the validity of iterators and references [26.3.9.5/1]

• array: As a rule, iterators to an array are never invalidated throughout the lifetime of the array. One should take note, however, that during swap, the iterator will continue to point to the same array element, and will thus change its value.

Associative Containers

• All Associative Containers: The insert and emplace members shall not affect the validity of iterators and references to the container [26.2.6/9]

Unordered Associative Containers

• All Unordered Associative Containers: Rehashing invalidates iterators, changes ordering between elements, and changes which buckets elements appear in, but does not invalidate pointers or references to elements. [26.2.7/9]
  The insert and emplace members shall not affect the validity of references to container elements, but may invalidate all iterators to the container. [26.2.7/14]
  The insert and emplace members shall not affect the validity of iterators if (N+n) <= z * B, where N is the number of elements in the container prior to the insert operation, n is the number of elements inserted, B is the container’s bucket count, and z is the container’s maximum load factor. [26.2.7/15]

• All Unordered Associative Containers: In case of a merge operation (e.g., a.merge(a2)), iterators referring to the transferred elements and all iterators referring to a will be invalidated, but iterators to elements remaining in a2 will remain valid. (Table 91 — Unordered associative container requirements)

Container Adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

Erasure

Sequence Containers

• vector: The functions erase and pop_back invalidate iterators and references at or after the point of the erase. [26.3.11.5/3]

• deque: An erase operation that erases the last element of a deque invalidates only the past-the-end iterator and all iterators and references to the erased elements. An erase operation that erases the first element of a deque but not the last element invalidates only iterators and references to the erased elements. An erase operation that erases neither the first element nor the last element of a deque invalidates the past-the-end iterator and all iterators and references to all the elements of the deque. [ Note: pop_front and pop_back are erase operations. —end note ] [26.3.8.4/4]

• list: Invalidates only the iterators and references to the erased elements. [26.3.10.4/3]. This applies to erase, pop_front, pop_back, clear functions.
  remove and remove_if member functions: Erases all the elements in the list referred by a list iterator i for which the following conditions hold: *i == value, pred(*i) != false. Invalidates only the iterators and references to the erased elements [26.3.10.5/15].
  unique member function - Erases all but the first element from every consecutive group of equal elements referred to by the iterator i in the range [first + 1, last) for which *i == *(i-1) (for the version of unique with no arguments) or pred(*i, *(i - 1)) (for the version of unique with a predicate argument) holds. Invalidates only the iterators and references to the erased elements. [26.3.10.5/19]

• forward_list: erase_after shall invalidate only iterators and references to the erased elements. [26.3.9.5/1].
  remove and remove_if member functions - Erases all the elements in the list referred by a list iterator i for which the following conditions hold: *i == value (for remove()), pred(*i) is true (for remove_if()). Invalidates only the iterators and references to the erased elements. [26.3.9.6/12].
  unique member function - Erases all but the first element from every consecutive group of equal elements referred to by the iterator i in the range [first + 1, last) for which *i == *(i-1) (for the version with no arguments) or pred(*i, *(i - 1)) (for the version with a predicate argument) holds. Invalidates only the iterators and references to the erased elements. [26.3.9.6/16]

• All Sequence Containers: clear invalidates all references, pointers, and iterators referring to the elements of a and may invalidate the past-the-end iterator (Table 87 — Sequence container requirements). But for forward_list, clear does not invalidate past-the-end iterators. [26.3.9.5/32]

• All Sequence Containers: assign invalidates all references, pointers and iterators referring to the elements of the container. For vector and deque, also invalidates the past-the-end iterator. (Table 87 — Sequence container requirements)

Associative Containers

• All Associative Containers: The erase members shall invalidate only iterators and references to the erased elements [26.2.6/9]

• All Associative Containers: The extract members invalidate only iterators to the removed element; pointers and references to the removed element remain valid [26.2.6/10]

Container Adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

General container requirements relating to iterator invalidation:

• Unless otherwise specified (either explicitly or by defining a function in terms of other functions), invoking a container member function or passing a container as an argument to a library function shall not invalidate iterators to, or change the values of, objects within that container. [26.2.1/12]

• no swap() function invalidates any references, pointers, or iterators referring to the elements of the containers being swapped. [ Note: The end() iterator does not refer to any element, so it may be invalidated. —end note ] [26.2.1/(11.6)]

As examples of the above requirements:

• transform algorithm: The op and binary_op functions shall not invalidate iterators or subranges, or modify elements in the ranges [28.6.4/1]

• accumulate algorithm: In the range [first, last], binary_op shall neither modify elements nor invalidate iterators or subranges [29.8.2/1]

• reduce algorithm: binary_op shall neither invalidate iterators or subranges, nor modify elements in the range [first, last]. [29.8.3/5]

and so on...

The single pipe, |, is one of the bitwise operators.

From Wikipedia:

In the C programming language family, the bitwise OR operator is "|" (pipe). Again, this operator must not be confused with its Boolean "logical or" counterpart, which treats its operands as Boolean values, and is written "||" (two pipes).

Nothing work for me but when i set tint color it works on Shape Drawable

 Drawable background = imageView.getBackground();
 background.setTint(getRandomColor())

require android 5.0 API 21

This working for me

ng-selected="true" 

Use .push:

items.push({'id':5});

Use these classes: navbar-brand mx-auto

All other solutions overcomplicate the matter.

That's rather hard to say - in order to really find out which one works better, you'd need to actually profile the execution times.

As a general rule of thumb, I think if you have indices on your foreign key columns, and if you're using only (or mostly) INNER JOIN conditions, then the JOIN will be slightly faster.

But as soon as you start using OUTER JOIN, or if you're lacking foreign key indexes, the IN might be quicker.

The answers seems a bit over complicated. I hope I didn't misunderstand the question.

If you simply want to open a fancy box from a click to an "A" tag. Just set your html to

<a id="my_fancybox" href="#contentdiv">click me</a>

The contents of your box will be inside of a div with id "contentdiv" and in your javascript you can initialize fancybox like this:

$('#my_fancybox').fancybox({
    'autoScale': true,
    'transitionIn': 'elastic',
    'transitionOut': 'elastic',
    'speedIn': 500,
    'speedOut': 300,
    'autoDimensions': true,
    'centerOnScroll': true,
});

This will show a fancybox containing "contentdiv" when your anchor tag is clicked.

You can use cstdlib

Although- http://www.cplusplus.com/articles/j3wTURfi/

#include <cstdlib>

const int dir= system("mkdir -p foo");
if (dir< 0)
{
     return;
}

you can also check if the directory exists already by using

#include <dirent.h>

first, you need to load URL helper like this type or you can upload within autoload.php file:

$this->load->helper('url');

if (!$user_logged_in)
{
  redirect('/account/login', 'refresh');
}

Sign-off is a requirement for getting patches into the Linux kernel and a few other projects, but most projects don't actually use it.

It was introduced in the wake of the SCO lawsuit, (and other accusations of copyright infringement from SCO, most of which they never actually took to court), as a Developers Certificate of Origin. It is used to say that you certify that you have created the patch in question, or that you certify that to the best of your knowledge, it was created under an appropriate open-source license, or that it has been provided to you by someone else under those terms. This can help establish a chain of people who take responsibility for the copyright status of the code in question, to help ensure that copyrighted code not released under an appropriate free software (open source) license is not included in the kernel.

To expound on Numenor's answer you can do something like, Format(Now(),"HH:mm:ss") using these custom date/time formating options

HTML5 has been supported by all of the major browsers for many years already. There is absolutely no reason that you should have to make this from scratch on your own or polyfill it! Literally just use input.labels and it solves all of your problems.

It depends why the something is on the same line in the first place.

clear in the case of floats, display: block in the case of inline content naturally flowing, nothing will defeat position: absolute as the previous element will be taken out of the normal flow by it.

Upcasting (using (Employee)someInstance) is generally easy as the compiler can tell you at compile time if a type is derived from another.

Downcasting however has to be done at run time generally as the compiler may not always know whether the instance in question is of the type given. C# provides two operators for this - is which tells you if the downcast works, and return true/false. And as which attempts to do the cast and returns the correct type if possible, or null if not.

To test if an employee is a manager:

Employee m = new Manager();
Employee e = new Employee();

if(m is Manager) Console.WriteLine("m is a manager");
if(e is Manager) Console.WriteLine("e is a manager");

You can also use this

Employee someEmployee = e  as Manager;
    if(someEmployee  != null) Console.WriteLine("someEmployee (e) is a manager");

Employee someEmployee = m  as Manager;
    if(someEmployee  != null) Console.WriteLine("someEmployee (m) is a manager");

Move your map variable into a scope where the event listener can use it. You are creating the map inside your initialize() function and nothing else can use it when created that way.

var map; //<-- This is now available to both event listeners and the initialize() function
function initialize() {
  var mapOptions = {
   center: new google.maps.LatLng(40.5472,12.282715),
   zoom: 6,
   mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById("map-canvas"),
            mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
google.maps.event.addDomListener(window, "resize", function() {
 var center = map.getCenter();
 google.maps.event.trigger(map, "resize");
 map.setCenter(center); 
});

You can always use Unicode character, for me personally this is the most clear solution:

var space = "\u0020"

In sass (scss):

 button {
  color: white;
  cursor: pointer;
  border-radius: 4px;

  &:disabled{
    opacity: 0.4;

    &:hover{
      opacity: 0.4;  //this is what you want
    }
  }

  &:hover{
    opacity: 0.9;
  }
}

You should append class not overwrite it

var headCSS = document.getElementsByTagName("html")[0].getAttribute("class") || "";
document.getElementsByTagName("html")[0].setAttribute("class",headCSS +"foo");

I would still recommend using jQuery to avoid browser incompatibilities

I was facing the same issue and then I find a solution. The solution is:

1. Close Visual Studio
2. Delete the SUO file
3. Restart Visual Studio

The .suo file is a hidden file in the same folder where the .svn solution file exists. Hope, it'll work!

control-shift-L should open the log(s) for you. this will by default be the messages log, but if you create the item that is creating the error the Compiler Log will show up (for me the box shows up in the bottom middle left).

if the messages log is the only log that shows up, simply re-execute the item that was causing the failure and the compiler log will show up

for instance, hit Control-shift-L then execute this

CREATE OR REPLACE FUNCTION TEST123() IS
BEGIN
VAR := 2;
end TEST123;

and you will see the message "Error(1,18): PLS-00103: Encountered the symbol ")" when expecting one of the following: current delete exists prior "

(You can also see this in "View--Log")

One more thing, if you are having a problem with a (function || package || procedure) if you do the coding via the SQL Developer interface (by finding the object in question on the connections tab and editing it the error will be immediately displayed (and even underlined at times)

stack size can indeed be unlimited. _STK_LIM is the default, _STK_LIM_MAX is something that differs per architecture, as can be seen from include/asm-generic/resource.h:

/*
 * RLIMIT_STACK default maximum - some architectures override it:
 */
#ifndef _STK_LIM_MAX
# define _STK_LIM_MAX           RLIM_INFINITY
#endif

As can be seen from this example generic value is infinite, where RLIM_INFINITY is, again, in generic case defined as:

/*
 * SuS says limits have to be unsigned.
 * Which makes a ton more sense anyway.
 *
 * Some architectures override this (for compatibility reasons):
 */
#ifndef RLIM_INFINITY
# define RLIM_INFINITY          (~0UL)
#endif

So I guess the real answer is - stack size CAN be limited by some architecture, then unlimited stack trace will mean whatever _STK_LIM_MAX is defined to, and in case it's infinity - it is infinite. For details on what it means to set it to infinite and what implications it might have, refer to the other answer, it's way better than mine.

Overall

SELECT
       COUNT(DISTINCT `site_id`) as distinct_sites
  FROM `cp_visits`
 WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)

Or per site

  SELECT
         `site_id` as site,
         COUNT(DISTINCT `user_id`) as distinct_users_per_site
    FROM `cp_visits`
   WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
GROUP BY `site_id`

Having the time column in the result doesn't make sense - since you are aggregating the rows, showing one particular time is irrelevant, unless it is the min or max you are after.

Why invent wheels yourself while there is a car ready for you? I just find this tools super easy and intuitive to use: Advanced Installer. This one minute video should be enough to impress you. Here is the illustrative user guide.

navigationController?.navigationBar.titleTextAttributes = textAttributes

Typically one uses an abstract class to provide some incomplete functionality that will be fleshed out by concrete subclasses. It may provide methods that are used by its subclasses; it may also represent an intermediate node in the class hierarchy, to represent a common grouping of concrete subclasses, distinguishing them in some way from other subclasses of its superclass. Since an interface can't derive from a class, this is another situation where a class (abstract or otherwise) would be necessary, versus an interface.

A good rule of thumb is that only leaf nodes of a class hierarchy should ever be instantiated. Making non-leaf nodes abstract is an easy way of ensuring that.

You can use %in%

If you have double-encoded UTF8 characters (various smart quotes, dashes, apostrophe ’, quotation mark “, etc), in mysql you can dump the data, then read it back in to fix the broken encoding.

Like this:

mysqldump -h DB_HOST -u DB_USER -p DB_PASSWORD --opt --quote-names \
    --skip-set-charset --default-character-set=latin1 DB_NAME > DB_NAME-dump.sql

mysql -h DB_HOST -u DB_USER -p DB_PASSWORD \
    --default-character-set=utf8 DB_NAME < DB_NAME-dump.sql

This was a 100% fix for my double encoded UTF-8.

Source: http://blog.hno3.org/2010/04/22/fixing-double-encoded-utf-8-data-in-mysql/

This will allow both positive and negative integers

ValidationExpression="^-?[0-9]\d*(\d+)?$"

1) Maybe oveflow: hidden; will do the trick?

2) You need to set the size of each div with the text and button so that each of these divs have the same height. Then for your button:

button {
  position: absolute;
  bottom: 0;
}

Use this in your main thread: while(!executor.isTerminated()); Put this line of code after starting all the threads from executor service. This will only start the main thread after all the threads started by executors are finished. Make sure to call executor.shutdown(); before the above loop.

Knowing the parent of an element is useful when you are trying to position them out the "real-flow" of elements.

Below given code will output the id of parent of element whose id is provided. Can be used for misalignment diagnosis.

<!-- Patch of code to find parent -->
<p id="demo">Click the button </p>
<button onclick="parentFinder()">Find Parent</button>
<script>
function parentFinder()
{
    var x=document.getElementById("demo"); 
    var y=document.getElementById("*id of Element you want to know parent of*");
    x.innerHTML=y.parentNode.id;
}
</script>
<!-- Patch ends -->

Here is the answer for those of you who need a Boostrap 3 solution.

In bootstrap 3 use 'shown.bs.tab' instead of 'shown' in the next line

// tab
$('#rowTab a:first').tab('show');

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
//show selected tab / active
 console.log ( $(e.target).attr('id') );
});

<ion-row *ngIf="cat === 1;else second"></ion-row>_x000D_
<ng-template #second>_x000D_
    <ion-row *ngIf="cat === 2;else third"></ion-row>_x000D_
</ng-template>_x000D_
<ng-template #third>_x000D_
_x000D_
</ng-template>

Angular is already using ng-template under the hood in many of the structural directives that we use all the time: ngIf, ngFor and ngSwitch.

> What is ng-template in Angular

If there is not ISNULL() method, you can use this expression instead:

CASE WHEN fieldname IS NULL THEN 0 ELSE fieldname END

This works the same as ISNULL(fieldname, 0).

1)your id should have sys dba access 2)

select sum(a.value) total_cur, avg(a.value) avg_cur, max(a.value) max_cur, 
 s.username, s.machine
 from v$sesstat a, v$statname b, v$session s 
 where a.statistic# = b.statistic# and s.sid=a.sid
 and b.name = 'opened cursors current' 
 group by s.username, s.machine
 order by 1 desc;

Remember that this eventually has to end up in a relational database. So using relations really is the common way to solve this problem. If you absolutely insist on storing a list in the object itself, you could make it for example comma-separated, and store it in a string, and then provide accessor functions that split the string into a list. With that, you will be limited to a maximum number of strings, and you will lose efficient queries.

Probably you are trying to access the excel with the index 0, please note that Excel rows/columns start from 1.

When I started using json, I was confused and unable to figure it out for some time, but finally I got what I wanted
Here is the simple solution

import json
m = {'id': 2, 'name': 'hussain'}
n = json.dumps(m)
o = json.loads(n)
print(o['id'], o['name'])

I have added a helper da() to Laravel which in fact works as an alias for dd($object->toArray())

Here is the Gist: https://gist.github.com/TommyZG/0505eb331f240a6324b0527bc588769c

If you need access to the internal states of a function, you're possibly better off using a class. You can make a class instance behave like a function by making it a callable, which is done by defining __call__:

class StatefulFunction( object ):
    def __init__( self ):
        self.public_value = 'foo'

    def __call__( self ):
        return self.public_value


>> f = StatefulFunction()
>> f()
`foo`
>> f.public_value = 'bar'
>> f()
`bar`

I faced the same question. I want to add some info to the user-agent, also need to keep the original user-agent of webview. I solved it by using the code below:

    //get the original user-agent of webview
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectZero];
NSString *oldAgent = [webView stringByEvaluatingJavaScriptFromString:@"navigator.userAgent"];
NSLog(@"old agent :%@", oldAgent);

//add my info to the new agent
NSString *newAgent = [oldAgent stringByAppendingString:@" Jiecao/2.4.7 ch_appstore"];
NSLog(@"new agent :%@", newAgent);

//regist the new agent
NSDictionary *dictionnary = [[NSDictionary alloc] initWithObjectsAndKeys:newAgent, @"UserAgent", nil];
[[NSUserDefaults standardUserDefaults] registerDefaults:dictionnary];

Use it before you instancing webview.

X is a dataframe and can't be accessed via slice terminology like X[:, 3]. You must access via iloc or X.values. However, the way you constructed X made it a copy... so. I'd use values

# Importing the libraries
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd

# Importing the dataset
# dataset = pd.read_csv('50_Startups.csv')

dataset = pd.DataFrame(np.random.rand(10, 10))
y=dataset.iloc[:, 4]
X=dataset.iloc[:, 0:4]

# Encoding categorical data
from sklearn.preprocessing import LabelEncoder, OneHotEncoder
labelencoder_X = LabelEncoder()

#  I changed this line
X.values[:, 3] = labelencoder_X.fit_transform(X.values[:, 3])

I am changing your id to current-month (having no space)

alert($('#current-month').attr('month'));
alert($('#current-month').attr('year'));

Example for you to work from

HTML:

<input type="text" value="This is some text" id="text" style="width: 150px;" />
<br />
<input type="button" value="Click Me" id="button" />?

jQuery:

<script type="text/javascript">
$(function () {
    $('#button').on('click', function () {
        var text = $('#text');
        text.val(text.val() + ' after clicking');    
    });
});
<script>

Javascript

<script type="text/javascript">
document.getElementById("button").addEventListener('click', function () {
    var text = document.getElementById('text');
    text.value += ' after clicking';
});
</script>

DEMO

To Fix the Problem:

Make a Batch file with the following code:

@echo off
reg query "HKEY_CLASSES_ROOT\typelib\{831FDD16-0C5C-11D2-A9FC-0000F8754DA1}\2.1"
if %errorlevel%==0 GOTO DELREGKEY
if %errorlevel%==1 GOTO REGISTEROCX

:DELREGKEY
reg delete hkcr\typelib\{831FDD16-0C5C-11D2-A9FC-0000F8754DA1}\2.0 /f

:REGISTEROCX
if exist %systemroot%\SysWOW64\cscript.exe goto 64 
%systemroot%\system32\regsvr32 /u mscomctl.ocx /s
%systemroot%\system32\regsvr32 mscomctl.ocx /s
exit

:64 
%systemroot%\sysWOW64\regsvr32 /u mscomctl.ocx /s
%systemroot%\sysWOW64\regsvr32 mscomctl.ocx /s
exit

Some of the above solutions did not work for me. The .fig attribute was not found when I tried that and I was unable to use .savefig() directly. However, what did work was:

sns_plot.figure.savefig("output.png")

I am a newer Python user, so I do not know if this is due to an update. I wanted to mention it in case anybody else runs into the same issues as I did.

@echo off

set "language=de"

IF "%language%" == "de" (
    goto languageDE
) ELSE (
    IF "%language%" == "en" (
        goto languageEN
    ) ELSE (
    echo Not found.
    )
)

:languageEN
:languageDE

echo %language%

This works , but not sure how your language variable is defined.Does it have spaces in its definition.

You're looking for the OpenFileDialog class.

For example:

Sub SomeButton_Click(sender As Object, e As EventArgs) Handles SomeButton.Click
    Using dialog As New OpenFileDialog
        If dialog.ShowDialog() <> DialogResult.OK Then Return
        File.Copy(dialog.FileName, newPath)
    End Using
End Sub

Please try this code:-

$url = 'url_to_post';

$data = array("first_name" => "First name","last_name" => "last name","email"=>"[email protected]","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" =>  "Mother","last_name" =>  "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );

$data_string = json_encode(array("customer" =>$data));

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);

curl_close($ch);

echo "$result";

I also used the base_path() function and it worked for me.

You can use the lower function:

Guide.where("lower(title)='attack'") 

As a comment: Work on your question. The title isn't terribly informative, and you drop a big chunk of code at the end that is irrelevant to your question.

Once you have Selected a group of sheets, you can use Selection

Consider:

Sub luxation()
    ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
    Selection.ExportAsFixedFormat _
        Type:=xlTypePDF, _
        Filename:="C:\TestFolder\temp.pdf", _
        Quality:=xlQualityStandard, _
        IncludeDocProperties:=True, _
        IgnorePrintAreas:=False, _
        OpenAfterPublish:=True
End Sub

EDIT#1:

Further testing has reveled that this technique depends on the group of cells selected on each worksheet. To get a comprehensive output, use something like:

Sub Macro1()

   Sheets("Sheet1").Activate
   ActiveSheet.UsedRange.Select
   Sheets("Sheet2").Activate
   ActiveSheet.UsedRange.Select
   Sheets("Sheet3").Activate
   ActiveSheet.UsedRange.Select

   ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
   Selection.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
      "C:\Users\James\Desktop\pdfmaker.pdf", Quality:=xlQualityStandard, _
      IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
      True
End Sub

I completely respect using Beautiful Soup to get rendered content, but it may not be the ideal package for acquiring the rendered content on a page.

I had a similar problem to get rendered content, or the visible content in a typical browser. In particular I had many perhaps atypical cases to work with such a simple example below. In this case the non displayable tag is nested in a style tag, and is not visible in many browsers that I have checked. Other variations exist such as defining a class tag setting display to none. Then using this class for the div.

<html>
  <title>  Title here</title>

  <body>

    lots of text here <p> <br>
    <h1> even headings </h1>

    <style type="text/css"> 
        <div > this will not be visible </div> 
    </style>


  </body>

</html>

One solution posted above is:

html = Utilities.ReadFile('simple.html')
soup = BeautifulSoup.BeautifulSoup(html)
texts = soup.findAll(text=True)
visible_texts = filter(visible, texts)
print(visible_texts)


[u'\n', u'\n', u'\n\n        lots of text here ', u' ', u'\n', u' even headings ', u'\n', u' this will not be visible ', u'\n', u'\n']

This solution certainly has applications in many cases and does the job quite well generally but in the html posted above it retains the text that is not rendered. After searching SO a couple solutions came up here BeautifulSoup get_text does not strip all tags and JavaScript and here Rendered HTML to plain text using Python

I tried both these solutions: html2text and nltk.clean_html and was surprised by the timing results so thought they warranted an answer for posterity. Of course, the speeds highly depend on the contents of the data...

One answer here from @Helge was about using nltk of all things.

import nltk

%timeit nltk.clean_html(html)
was returning 153 us per loop

It worked really well to return a string with rendered html. This nltk module was faster than even html2text, though perhaps html2text is more robust.

betterHTML = html.decode(errors='ignore')
%timeit html2text.html2text(betterHTML)
%3.09 ms per loop

getJSONArray(attrname) will get you an array from the object of that given attribute name in your case what is happening is that for

{"abridged_cast":["name": blah...]}
^ its trying to search for a value "characters"

but you need to get into the array and then do a search for "characters"

try this

String json="{'abridged_cast':[{'name':'JeffBridges','id':'162655890','characters':['JackPrescott']},{'name':'CharlesGrodin','id':'162662571','characters':['FredWilson']},{'name':'JessicaLange','id':'162653068','characters':['Dwan']},{'name':'JohnRandolph','id':'162691889','characters':['Capt.Ross']},{'name':'ReneAuberjonois','id':'162718328','characters':['Bagley']}]}";

    JSONObject jsonResponse;
    try {
        ArrayList<String> temp = new ArrayList<String>();
        jsonResponse = new JSONObject(json);
        JSONArray movies = jsonResponse.getJSONArray("abridged_cast");
        for(int i=0;i<movies.length();i++){
            JSONObject movie = movies.getJSONObject(i);
            JSONArray characters = movie.getJSONArray("characters");
            for(int j=0;j<characters.length();j++){
                temp.add(characters.getString(j));
            }
        }
        Toast.makeText(this, "Json: "+temp, Toast.LENGTH_LONG).show();
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

checked it :)

Well, technically '\0' is a character while "\0" is a string, so if you're checking for the null termination character the former is correct. However, as Chris Lutz points out in his answer, your comparison won't work in it's current form.

.bashrc is not sourced when you log in using SSH. You need to source it in your .bash_profile like this:

if [ -f ~/.bashrc ]; then
  . ~/.bashrc
fi

The only thing that can be work is (if we mention that the passwords are just hashed, without adding any kind of salt to prevent the replay attacks, if it is so you must know the salt)by the way, get an dictionary attack tool, the files of many words, numbers etc. then create two rows, one row is word,number (in dictionary) the other one is hash of the word, and compare the hashes if matches you get it...

that's the only way, without going into cryptanalysis.

It's possible to argue that using SSHs key to authenticate is less secure because we tend to change our password more periodically than we generate new SSH keys.

Servers that limit the lifespan for which they'll honor given SSH keys can help force users toward the practice of refreshing SSH-keys periodically.

This thing is empty nested list from which ne will append data to empty dict

ls = [['a','a1','a2','a3'],['b','b1','b2','b3'],['c','c1','c2','c3'], 
['d','d1','d2','d3']]

this means to create four empty dict inside data_dict

data_dict = {f'dict{i}':{} for i in range(4)}
for i in range(4):
    upd_dict = {'val' : ls[i][0], 'val1' : ls[i][1],'val2' : ls[i][2],'val3' : ls[i][3]}

    data_dict[f'dict{i}'].update(upd_dict)

print(data_dict)

The output

{'dict0': {'val': 'a', 'val1': 'a1', 'val2': 'a2', 'val3': 'a3'}, 'dict1': {'val': 'b', 'val1': 'b1', 'val2': 'b2', 'val3': 'b3'},'dict2': {'val': 'c', 'val1': 'c1', 'val2': 'c2', 'val3': 'c3'}, 'dict3': {'val': 'd', 'val1': 'd1', 'val2': 'd2', 'val3': 'd3'}}

In addition to others' answers :

static:: will be computed using runtime information.

That means you can't use static:: in a class property because properties values :

Must be able to be evaluated at compile time and must not depend on run-time information.

class Foo {
    public $name = static::class;

}

$Foo = new Foo;
echo $Foo->name; // Fatal error

Using self::

class Foo {
    public $name = self::class;

}
$Foo = new Foo;
echo $Foo->name; // Foo

Please note that the Fatal error comment in the code i made doesn't indicate where the error happened, the error happened earlier before the object was instantiated as @Grapestain mentioned in the comments

I have the same problem. I avoid it with remove.packages("Package making this confusion") and it works. In my case, I don't need the second package, so that is not a very good idea.

How to fix this issue ?

Read the data using the correct character encoding. The error message means that you are trying to read the data as UTF-8 (either deliberately or because that is the default encoding for an XML file that does not specify <?xml version="1.0" encoding="somethingelse"?>) but it is actually in a different encoding such as ISO-8859-1 or Windows-1252.

To be able to advise on how you should do this I'd have to see the code you're currently using to read the XML.

RanRag has already answered it for your specific question.

However, more generally, what you are doing with

if [[ "$string" =~ ^hello ]]

is a regex match. To do the same in Python, you would do:

import re
if re.match(r'^hello', somestring):
    # do stuff

Obviously, in this case, somestring.startswith('hello') is better.

The subprocess module has come along way since 2008. In particular check_call and check_output make simple subprocess stuff even easier. The check_* family of functions are nice it that they raise an exception if something goes wrong.

import os
import subprocess

files = os.listdir('.')
for f in files:
   subprocess.check_call( [ 'myscript', f ] )

Any output generated by myscript will display as though your process produced the output (technically myscript and your python script share the same stdout). There are a couple of ways to avoid this.

• check_call( [ 'myscript', f ], stdout=subprocess.PIPE )
  The stdout will be supressed (beware if myscript produces more that 4k of output). stderr will still be shown unless you add the option stderr=subprocess.PIPE.
• check_output( [ 'myscript', f ] )
check_output returns the stdout as a string so it isnt shown. stderr is still shown unless you add the option stderr=subprocess.STDOUT.

The .sh is for *nix systems and .bat should be for Windows. Since your example shows a bash error and you mention Terminal, I'm assuming it's OS X you're using.

In this case you should go to the folder and type:

./startup.sh

./ just means that you should call the script located in the current directory. (Alternatively, just type the full path of the startup.sh). If it doesn't work then, check if startup.sh has execute permissions.

You can simply call

program "file"

from the batch file for the vast majority of programs. Don't mess with start unless you absolutely need it; it has various weird side-effects that make your life only harder.

The The point here is that pretty much every program that does something with files allows passing the name of the file to do something with in the command line. If that weren't the case, then you couldn't double-click files in the graphical shell to open them, for example.

If the program you're executing is a console application, then it will run in the current console window and the batch file will continue afterwards. If the program is a GUI program (i.e. not a console program; that's a distinction in the EXE) then the batch file will continue immediately after starting it.

Like said here and below, a failed request (i.e. the server is not found) returns false, no HTTP status code, since a reply has never been received.

Call curl_error().

You can add a specific url to each point, e.g.:

var points = [
    ['name1', 59.9362384705039, 30.19232525792222, 12, 'www.google.com'],
    ['name2', 59.941412822085645, 30.263564729357767, 11, 'www.amazon.com'],
    ['name3', 59.939177197629455, 30.273554411974955, 10, 'www.stackoverflow.com']
];

Add the url to the marker values in the for-loop:

var marker = new google.maps.Marker({
    ...
    zIndex: place[3],
    url: place[4]
});

Then you can add just before to the end of your for-loop:

google.maps.event.addListener(marker, 'click', function() {
    window.location.href = this.url;
});

Also see this example.

This works for me:

string dateTimeString = "21?-?10?-?2014? ?15?:?40?:?30";
dateTimeString = Regex.Replace(dateTimeString, @"[^\u0000-\u007F]", string.Empty);

string inputFormat = "dd-MM-yyyy HH:mm:ss";
string outputFormat = "yyyy-MM-dd HH:mm:ss";
var dateTime = DateTime.ParseExact(dateTimeString, inputFormat, CultureInfo.InvariantCulture);
string output = dateTime.ToString(outputFormat);

Console.WriteLine(output);

Update your

<li>
  <a href="#about">About</a>
</li>

to

<li>
  <a data-toggle="collapse" data-target=".nav-collapse" href="#about">About</a>
</li>

This simple change worked for me.

>>> from operator import itemgetter
>>> data = [('abc', 121),('abc', 231),('abc', 148), ('abc',221)]
>>> sorted(data,key=itemgetter(1))
[('abc', 121), ('abc', 148), ('abc', 221), ('abc', 231)]

IMO using itemgetter is more readable in this case than the solution by @cheeken. It is also faster since almost all of the computation will be done on the c side (no pun intended) rather than through the use of lambda.

>python -m timeit -s "from operator import itemgetter; data = [('abc', 121),('abc', 231),('abc', 148), ('abc',221)]" "sorted(data,key=itemgetter(1))"
1000000 loops, best of 3: 1.22 usec per loop

>python -m timeit -s "data = [('abc', 121),('abc', 231),('abc', 148), ('abc',221)]" "sorted(data,key=lambda x: x[1])"
1000000 loops, best of 3: 1.4 usec per loop

I know this question is answered still, I would like to pass an information how to get source code from apk with out dexjar.

There is an online decompiler for android apks

1. Upload apk from local machine
2. Wait some moments
3. Download source code in zip format

I don't know how reliable is this.

@darkheir Answer is the manual way to do decompile apk. It helps us to understand different phases in Apk creation.

Once you have source code , follow the step mentioned in the accepted answer

Report so many ads on this links Another online Apk De-compiler @Andrew Rukin : http://www.javadecompilers.com/apk

Still worth. Hats Off to creators.

If you want to see the default browser errors being displayed, for example, those triggered by HTML attributes (showing up before any client-code JS treatment):

<input name="o" required="required" aria-required="true" type="text">

You should use the submit event instead of the click event. In this case a popup will be automatically displayed requesting "Please fill out this field". Even with preventDefault:

$('form').on('submit', function(event) {
   event.preventDefault();
   my_form_treatment(this, event);
}); // -> this will show up a "Please fill out this field" pop-up before my_form_treatment

As someone mentioned previously, return false would stop propagation (i.e. if there are more handlers attached to the form submission, they would not be executed), but, in this case, the action triggered by the browser will always execute first. Even with a return false at the end.

So if you want to get rid of these default pop-ups, use the click event on the submit button:

$('form input[type=submit]').on('click', function(event) {
   event.preventDefault();
   my_form_treatment(this, event);
}); // -> this will NOT show any popups related to HTML attributes

^\d+(\.\d{1,2})?$

will allow:

1. 244
2. 10.89
3. 9.5

will disallow:

2. 10.
3. 10.8.9

I was also facing this issue for quite long time. Below are the steps that I perform, and it works for me always:

• Deleting the solution's .suo file.
• Deleting the Temporary ASP.NET Files (You can find it at find it at %WINDOW%\Microsoft.NET\Framework\Temporary ASP.NET Files)
• Deleting all breakpoints in the application.

In my case, I had a very similar problem. I was updating my view inside a function that was being called by a parent component, and in my parent component I forgot to use @ViewChild(NameOfMyChieldComponent). I lost at least 3 hours just for this stupid mistake. i.e: I didn't need to use any of those methods:

• ChangeDetectorRef.detectChanges()
• ChangeDetectorRef.markForCheck()
• ApplicationRef.tick()

Also you can download and execute the install.bat file in 'ODAC112030Xcopy.zip' from 64-bit Oracle Data Access Components (ODAC) Downloads. This resolved my problem.

I also had this problem with a Java program trying to send a command on a server via SSH. The problem was with the machine executing the Java code. It didn't have the permission to connect to the remote server. The write() method was doing alright, but the read() method was throwing a java.net.SocketException: Connection reset. I fixed this problem with adding the client SSH key to the remote server known keys.

Is it legal? Yes, changing your location on Android is legal. Likewise, you can change VPN settings in Microsoft Edge on your PC, and all this is within the law. VPN allows you to change your IP address, safeguarding your privacy and protecting your actual location from being exposed. However, VPN laws may vary from country to country. There are restrictions in some regions.

Brief summary: Yes, you can change your region on Android and a VPN is a necessary assistant for this. It's simple, safe and legal. Today, VPN is the best way to change the region and unblock sites with regional restrictions.

What about running the google-drive-ftp-adapter application in your local pc and then connect your filezilla client to that application? The google-drive-ftp-adapter application is not an online service, but its an alternative solution to connect to google drive through ftp.

The google-drive-ftp-adapter is an open source application hosted in github and it is a kind of standalone ftp-server java application that connects to your google drive in behalf of you, acting as a bridge (or adapter) between your ftp client and the google drive service. Once you have running the google-drive-ftp adapter, you can connect your preferred FTP client to the google-drive-ftp-adapter ftp server in your localhost (or wherever the app is running, like in a remote machine) to manage your files.

I use it in conjunction with beyond compare to synchronize my local files against the ones I have in the google drive and it serves well for the purpose.

This is the current github link hosting the google-drive-ftp-adapter repository: https://github.com/andresoviedo/google-drive-ftp-adapter

There is a setting inside the PDF file that turns on the allow saving with data bit. However, it requires that you have a copy of Adobe Acrobat installed to change the bit.

The only other option is to print it to a PDF print driver which would save the data merged with the pdf file.

What errors are you seeing in the browser? I can understand why your code doesn't work if what you posted was incomplete, but without knowing that I can't know for sure.

<!DOCTYPE html>
<html>
  <head>
    <script src="http://code.jquery.com/jquery-1.5.js"></script>

      function countChar(val) {
        var len = val.value.length;
        if (len >= 500) {
          val.value = val.value.substring(0, 500);

... works fine for me.

Edit: You should probably clear the charNum div, or write something, if they are over the limit.

Let's say that your list name is A

Then you can code the following and you will have it as a csv file (columns only!)

R="\n".join(A)
f = open('Columns.csv','w')

f.close()

All of these answers are wrong!

Like I said in my comment, the reason you're getting that error because the URL fails the "Same origin policy", but you can still us the AJAX function to hit another domain, see Nick Cravers answer on this similar question:

You need to trigger JSONP behavior with $.getJSON() by adding &callback=? on the querystring, like this:

$.getJSON("http://en.wikipedia.org/w/api.php?action=query&prop=revisions&rvprop=content&titles="+title+"&format=json&callback=?",
function(data) {
    doSomethingWith(data); 
}); 

You can test it here.

Without using JSONP you're hitting the same-origin policy which is blocking the XmlHttpRequest from getting any data back.

With this in mind, the follow code should work:

var fbURL="https://graph.facebook.com/16453004404_481759124404/comments?access_token=my_token";

$.ajax({
    url: fbURL+"&callback=?",
    data: "message="+commentdata,
    type: 'POST',
    success: function (resp) {
        alert(resp);
    },
    error: function(e) {
        alert('Error: '+e);
    }  
});

ARGH!

I found it... I didn't have an extra package, called Microsoft.Owin.Host.SystemWeb

Once i searched and installed this, it worked.

Now - i am not sure if i just missed everything, though found NO reference to such a library or package when going through various tutorials. It also didn't get installed when i installed all this Identity framework... Not sure if it were just me..

EDIT Although it's in the Microsoft.Owin.Host.SystemWeb assembly it is an extension method in the System.Web namespace, so you need to have the reference to the former, and be using the latter.

Taken from The Hitchhiker's Guide to Python (Line Continuation):

When a logical line of code is longer than the accepted limit, you need to split it over multiple physical lines. The Python interpreter will join consecutive lines if the last character of the line is a backslash. This is helpful in some cases, but should usually be avoided because of its fragility: a white space added to the end of the line, after the backslash, will break the code and may have unexpected results.

A better solution is to use parentheses around your elements. Left with an unclosed parenthesis on an end-of-line the Python interpreter will join the next line until the parentheses are closed. The same behaviour holds for curly and square braces.

However, more often than not, having to split a long logical line is a sign that you are trying to do too many things at the same time, which may hinder readability.

Having that said, here's an example considering multiple imports (when exceeding line limits, defined on PEP-8), also applied to strings in general:

from app import (
    app, abort, make_response, redirect, render_template, request, session
)

I found the same issue with Node 12.19.0 and yarn 1.22.5 on Windows 10. I fixed the problem by installing latest stable python 64-bit with adding the path to Environment Variables during python installation. After python installation, I restarted my machine for env vars.

Ok, I tried as suggested writing the json myself from the AuthenticationEntryPoint and it works.

Just for testing I changed the AutenticationEntryPoint by removing response.sendError

@Component("restAuthenticationEntryPoint")
public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint{

    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authenticationException) throws IOException, ServletException {
    
        response.setContentType("application/json");
        response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
        response.getOutputStream().println("{ \"error\": \"" + authenticationException.getMessage() + "\" }");

    }
}

In this way you can send custom json data along with the 401 unauthorized even if you are using Spring Security AuthenticationEntryPoint.

Obviously you would not build the json as I did for testing purposes but you would serialize some class instance.

In Spring Boot, you should add it to http.authenticationEntryPoint() part of SecurityConfiguration file.

You could use pandas plot as @Bharath suggest:

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

Output:

Updated:

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

Updated Pandas 0.21.0+ reindex_axis is deprecated, use reindex

from matplotlib.colors import ListedColormap

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

Output:

If you just want to know whether the certificate has expired (or will do so within the next N seconds), the -checkend <seconds> option to openssl x509 will tell you:

if openssl x509 -checkend 86400 -noout -in file.pem
then
  echo "Certificate is good for another day!"
else
  echo "Certificate has expired or will do so within 24 hours!"
  echo "(or is invalid/not found)"
fi

This saves having to do date/time comparisons yourself.

openssl will return an exit code of 0 (zero) if the certificate has not expired and will not do so for the next 86400 seconds, in the example above. If the certificate will have expired or has already done so - or some other error like an invalid/nonexistent file - the return code is 1.

(Of course, it assumes the time/date is set correctly)

Be aware that older versions of openssl have a bug which means if the time specified in checkend is too large, 0 will always be returned (https://github.com/openssl/openssl/issues/6180).

Your Applicant class is not scanned it seems. By default all packages starting with the root as the class where you have put @SpringBootApplication will be scanned.

suppose your main class "WebServiceApplication" is in "com.service.something", then all components that fall under "com.service.something" is scanned, and "com.service.applicant" will not be scanned.

You can either restructure your packages such that "WebServiceApplication" falls under a root package and all other components becomes part of that root package. Or you can include @SpringBootApplication(scanBasePackages={"com.service.something","com.service.application"}) etc such that "ALL" components are scanned and initialized in the spring container.

Update based on comment

If you have multiple modules that are being managed by maven/gradle, all spring needs is the package to scan. You tell spring to scan "com.module1" and you have another module which has its root package name as "com.module2", those components wont be scanned. You can even tell spring to scan "com" which will then scan all components in "com.module1." and "com.module2."

Update django-geoposition at least to version 0.2.3 and add this to settings.py:

GEOPOSITION_GOOGLE_MAPS_API_KEY = 'YOUR_API_KEY'

You can transform logical implication A => B to NOT A or B. This is one of the most basic laws of logic. In your case it is something like this:

SELECT *
FROM logs 
WHERE pw='correct' AND (id>=800 OR success=1)  
AND YEAR(timestamp)=2011

I also transformed NOT id<800 to id>=800, which is also pretty basic.

Alternatively, you could go with pgrep or Process Grep. (Busybox is needed)

You could do a adb shell pgrep com.example.app and it would display just the process Id.

As a suggestion, since Android is Linux, you can use most basic Linux commands with adb shell to navigate/control around. :D

>>> for i in range(1, 11):

This is how to do it so that the printing does not run behind the prompt on the next line.

To import a database, use the following command.

  mysql> create new_database;
  mysql> use new_database;
  mysql> source (Here you need to import the path of the sql file);
 eg:
  mysql> source E:/test/dump.sql;

You need to use forward slashes (/) even on Windows, e.g. E:/test/dump.sql instead of E:\test\dump.sql

Or double backslashes (\\) because of escaping, i.e. E:\\test\\dump.sql

Here are my "answers" (trying to be unique here, I don't actually recommend either for this particular case :-)

Using ord() and the special a <= b <= c form:

//starts_with_digit = ord('0') <= ord(mystring[0]) <= ord('9')
//I was thinking too much in C. Strings are perfectly comparable.
starts_with_digit = '0' <= mystring[0] <= '9'

(This a <= b <= c, like a < b < c, is a special Python construct and it's kind of neat: compare 1 < 2 < 3 (true) and 1 < 3 < 2 (false) and (1 < 3) < 2 (true). This isn't how it works in most other languages.)

Using a regular expression:

import re
//starts_with_digit = re.match(r"^\d", mystring) is not None
//re.match is already anchored
starts_with_digit = re.match(r"\d", mystring) is not None

You can use the createRef to change the state of the child component from the parent component. Here are all the steps.

1. Create a method to change the state in the child component.

   2 - Create a reference for the child component in parent component using React.createRef().

   3 - Attach reference with the child component using ref={}.

   4 - Call the child component method using this.yor-reference.current.method.

Parent component

class ParentComponent extends Component {
constructor()
{
this.changeChild=React.createRef()
}
  render() {
    return (
      <div>
        <button onClick={this.changeChild.current.toggleMenu()}>
          Toggle Menu from Parent
        </button>
        <ChildComponent ref={this.changeChild} />
      </div>
    );
  }
}

Child Component

class ChildComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      open: false;
    }
  }

  toggleMenu=() => {
    this.setState({
      open: !this.state.open
    });
  }

  render() {
    return (
      <Drawer open={this.state.open}/>
    );
  }
}

You can try using glob module:

import glob

for filepath in glob.iglob('my_dir/*.asm'):
    print(filepath)

and since Python 3.5 you can search subdirectories as well:

glob.glob('**/*.txt', recursive=True) # => ['2.txt', 'sub/3.txt']

From the docs:

The glob module finds all the pathnames matching a specified pattern according to the rules used by the Unix shell, although results are returned in arbitrary order. No tilde expansion is done, but *, ?, and character ranges expressed with [] will be correctly matched.

Even though the question is too old, but I would like to share the solution that worked for me because I already checked everything when it comes to this error. It was a pain, I spent two days trying and at the end the solution was:

If you are making your own module then add CommonModule in imports in your own module

Instead of using the "c" tags, you could also do the following:

<h:outputLink value="Images/thumb_02.jpg" target="_blank" rendered="#{not empty user or user.userId eq 0}" />
<h:graphicImage value="Images/thumb_02.jpg" rendered="#{not empty user or user.userId eq 0}" />

<h:outputLink value="/DisplayBlobExample?userId=#{user.userId}" target="_blank" rendered="#{not empty user and user.userId neq 0}" />
<h:graphicImage value="/DisplayBlobExample?userId=#{user.userId}" rendered="#{not empty user and user.userId neq 0}"/>

I think that's a little more readable alternative to skuntsel's alternative answer and is utilizing the JSF rendered attribute instead of nesting a ternary operator. And off the answer, did you possibly mean to put your image in between the anchor tags so the image is clickable?

simple if u are using php Just append the current time at the end of the css like

<link href="css/name.css?<?php echo 
time(); ?>" rel="stylesheet">

So now everytime u reload whatever it is , the time changes and browser thinks its a different file since the last bit keeps changing.... U can do this for any file u force the browser to always refresh using whatever scripting language u want

A modern native approach could make use of 'Array.from()' - for example: `

const el = document.getElementById('get-this-index')_x000D_
const index = Array.from(document.querySelectorAll('li')).indexOf(el)_x000D_
document.querySelector('h2').textContent = `index = ${index}`

<ul>_x000D_
  <li>zero_x000D_
  <li>one_x000D_
  <li id='get-this-index'>two_x000D_
  <li>three_x000D_
</ul>_x000D_
<h2></h2>

`

var redBox = $(".post");

var greenBox = $(".post1");

var offset = redBox.offset();

$(".post1").css({'left': +offset.left});
$(".post1").html("Left :" +offset.left);

You can multiply a list by an integer n to repeat the list n times:

buckets = [0] * 100

That's not how it works.

This bit ('AND' and 'OR' and 'NOT') will evaluate as 'NOT'. So your code is equivalent to::

while not 'NOT' in list: print 'No boolean operator'

You could try this:

while not set('AND' and 'OR' and 'NOT').union(list): print 'No boolean operator'

I have what I believe is a better solution than the $('html, body') hack.

It's not a one-liner, but the issue I had with $('html, body') is that if you log $(window).scrollTop() during the animation, you'll see that the value jumps all over the place, sometimes by hundreds of pixels (though I don't see anything like that happening visually). I needed the value to be predictable, so that I could cancel the animation if the user grabbed the scroll bar or twirled the mousewheel during the auto-scroll.

Here is a function will animate scrolling smoothly:

function animateScrollTop(target, duration) {
    duration = duration || 16;
    var scrollTopProxy = { value: $(window).scrollTop() };
    if (scrollTopProxy.value != target) {
        $(scrollTopProxy).animate(
            { value: target }, 
            { duration: duration, step: function (stepValue) {
                var rounded = Math.round(stepValue);
                $(window).scrollTop(rounded);
            }
        });
    }
}

Below is a more complex version that will cancel the animation on user interaction, as well as refiring until the target value is reached, which is useful when trying to set the scrollTop instantaneously (e.g. simply calling $(window).scrollTop(1000) — in my experience, this fails to work about 50% of the time.)

function animateScrollTop(target, duration) {
    duration = duration || 16;

    var $window = $(window);
    var scrollTopProxy = { value: $window.scrollTop() };
    var expectedScrollTop = scrollTopProxy.value;

    if (scrollTopProxy.value != target) {
        $(scrollTopProxy).animate(
            { value: target },

Thanks to @EdChum I was struggling with same problem especially when indexes do not match. Unfortunatly in pandas guide this case is missed (when you for example delete some rows)

import pandas as pd
t=pd.DataFrame()
t['a']=[1,2,3,4]
t=t.loc[t['a']>1] #now index starts from 1

u=pd.DataFrame()
u['b']=[1,2,3] #index starts from 0

#option 1
#keep index of t
u.index = t.index 

#option 2
#index of t starts from 0
t.reset_index(drop=True, inplace=True)

#now concat will keep number of rows 
r=pd.concat([t,u], axis=1)

"argument is of length zero" is a very specific problem that comes from one of my least-liked elements of R. Let me demonstrate the problem:

> FALSE == "turnip"
[1] FALSE
> TRUE == "turnip"
[1] FALSE
> NA == "turnip"
[1] NA
> NULL == "turnip"
logical(0)

As you can see, comparisons to a NULL not only don't produce a boolean value, they don't produce a value at all - and control flows tend to expect that a check will produce some kind of output. When they produce a zero-length output... "argument is of length zero".

(I have a very long rant about why this infuriates me so much. It can wait.)

So, my question; what's the output of sum(is.null(data[[k]]))? If it's not 0, you have NULL values embedded in your dataset and will need to either remove the relevant rows, or change the check to

if(!is.null(data[[k]][[k2]]) & temp > data[[k]][[k2]]){
    #do stuff
}

Hopefully that helps; it's hard to tell without the entire dataset. If it doesn't help, and the problem is not a NULL value getting in somewhere, I'm afraid I have no idea.

You have a JSON string, not an object. Tell jQuery that you expect a JSON response and it will parse it for you. Either use $.getJSON instead of $.get, or pass the dataType argument to $.get:

$.get(
    'index.php?r=admin/post/ajax',
    {"parentCatId":parentCatId},
    function(data){                     
        $.each(data, function(key, value){
            console.log(key + ":" + value)
        })
    },
    'json'
);

I used the following:

import matplotlib.pyplot as plt

p1 = plt.plot(dates, temp, 'r-', label="Temperature (celsius)")  
p2 = plt.plot(dates, psal, 'b-', label="Salinity (psu)")  
plt.legend(loc='upper center', numpoints=1, bbox_to_anchor=(0.5, -0.05),        ncol=2, fancybox=True, shadow=True)

plt.savefig('data.png')  
plt.show()  
f.close()
plt.close()

I found very important to use plt.show after saving the figure, otherwise it won't work.figure exported in png

The actual representation of a null pointer is irrelevant here. An integer literal with value zero (including 0 and any valid definition of NULL) can be converted to any pointer type, giving a null pointer, whatever the actual representation. So p != NULL, p != 0 and p are all valid tests for a non-null pointer.

You might run into problems with non-zero representations of the null pointer if you wrote something twisted like p != reinterpret_cast<void*>(0), so don't do that.

Although I've just noticed that your question is tagged C as well as C++. My answer refers to C++, and other languages may be different. Which language are you using?

Just to add into alread given answers, the following worked for me:

HTML:

<div id="div{{$index+1}}" data-ng-show="val{{$index}}">

Where $index is the loop index.

Javascript (where value is the passed parameter to the function and it will be the value of $index, current loop index):

var variable = "val"+value;
if ($scope[variable] === undefined)
{
    $scope[variable] = true;
}else {
    $scope[variable] = !$scope[variable];
}

With PowerShell 5.1 in Windows 10 you can use:

Get-SmbMapping | Remove-SmbMapping -Confirm:$false

e.g.

 ColorTranslator.ToHtml(Color.FromArgb(Color.Tomato.ToArgb()))

This can avoid the KnownColor trick.

ObjectReader reader = new ObjectMapper().readerFor(Map.class);

Map<String, String> map = reader.readValue("{\"foo\":\"val\"}");

Note that reader instance is Thread Safe.

I think the easiest way is to divide two integers and increase by one :

int r = list.Count() / 10;
r += (list.Count() % 10 == 0 ? 0 : 1);

No need of libraries or functions.

edited with the right code.

#1 I use the last one frequently when having buttons on the layout which are not generated (but static obviously).

If you use it in practice and in a business application, pay extra attention here, because when you use source obfuscater like ProGuard, you'll need to mark these methods in your activity as to not be obfuscated.

For archiving some kind of compile-time-security with this approach, have a look at Android Lint (example).

#2 Pros and cons for all methods are almost the same and the lesson should be:

Use what ever is most appropriate or feels most intuitive to you.

If you have to assign the same OnClickListener to multiple button instances, save it in the class-scope (#1). If you need a simple listener for a Button, make an anonymous implementation:

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        // Take action.
    }
});

I tend to not implement the OnClickListener in the activity, this gets a little confusing from time to time (especially when you implement multiple other event-handlers and nobody knows what this is all doing).

Just wanted to illustrate, in the context of nested lists, the usefulness of the hidden checkbox <input> approach @jeffmcneill recommends — a context where each shown/hidden element should hold its state independently of focus and the show/hide state of other elements on the page.

Giving values with a common set of beginning characters to the id attributes of all the checkboxes used for the shown/hidden elements on the page lets you use an economical [id^=""] selector scheme for the stylesheet rules that toggle your clickable element’s appearance and the related shown/hidden element’s display state back and forth. Here, my ids are ‘expanded-1,’ ‘expanded-2,’ ‘expanded-3.’

Note that I’ve also used @Diepen’s :after selector idea in order to keep the <label> element free of content in the html.

Note also that the <input> <label> <div class="collapsible"> sequence matters, and the corresponding CSS with + selector instead of ~.

The system doesn't record queries in that way. If you know you want to do that ahead of time though, you can use SQL Profiler to record what is coming in and track queries during the time Profiler is running.

If valuationId and user are JavaScript variables, and the source code is plain static HTML, not generated by any means, you should try:

<a href=# onclick="return ReAssign(valuationId,user)">Re-Assign</a>

If they are generated from PHP, and they contain string values, use the escaped quoting around each variables like this:

<?php
    echo '<a href=# onclick="return ReAssign(\'' + $valuationId + '\',\'' + $user + '\')">Re-Assign</a>';
?>

The logic is similar to the updated code in the question, which generates code using JavaScript (maybe using jQuery?): don't forget to apply the escaped quotes to each variable:

var user = element.UserName;
var valuationId = element.ValuationId;
$('#ValuationAssignedTable').append('<tr> <td><a href=# onclick="return ReAssign(\'' + valuationId + '\',\'' + user + '\')">Re-Assign</a> </td>  </tr>');

The moral of the story is

'someString(\''+'otherString'+','+'yetAnotherString'+'\')'

Will get evaluated as:

someString('otherString,yetAnotherString');

Whereas you would need:

someString('otherString','yetAnotherString');

You need to change permissions on the folder bootstrap/css. Your super user may be able to access it but it doesn't mean apache or nginx have access to it, that's why you still need to change the permissions.

Tip: I usually make the apache/nginx's user group owner of that kind of folders and give 775 permission to it.

Use a ByteArrayOutputStream. Here is the process:

• Get an InputStream to read data
• Create a ByteArrayOutputStream.
• Copy all the InputStream into the OutputStream
• Get your byte[] from the ByteArrayOutputStream using the toByteArray() method

Try it with Mysqldump

#mysqldump --host=the.remotedatabase.com -u yourusername -p yourdatabasename > /User/backups/adump.sql

If you need it to have as a condition in an other event, I solved it this way:

$('.classname').hover(
     function(){$(this).data('hover',true);},
     function(){$(this).data('hover',false);}
);

Then in another event, you can easily use it:

 if ($(this).data('hover')){
      //...
 }

(I see some using is(':hover') to solve this. But this is not (yet) a valid jQuery selector and does not work in all compatible browsers)

I was getting same errors after an install on Windows 10. And I tried restarting but it did not work, so I did the following (do not recommend if you have been working in docker for awhile, this was on a fresh install):

1) Find the whale in your system tray, and right click

2) Go to settings > Reset

3) Reset to factory defaults

I was then able to follow the starting docker tutorial on the website with Windows 10, and now it works like a charm.

I had same issue with external libraries like ROS headers. I like to use following options in CMakeLists.txt for stricter compilation:

set(CMAKE_CXX_FLAGS "-std=c++0x -Wall -Wextra -Wstrict-aliasing -pedantic -Werror -Wunreachable-code ${CMAKE_CXX_FLAGS}")

However doing this causes all kind of pedantic errors in externally included libraries as well. The solution is to disable all pedantic warnings before you include external libraries and re-enable like this:

//save compiler switches
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wpedantic"

//Bad headers with problem goes here
#include <ros/ros.h>
#include <sensor_msgs/LaserScan.h>

//restore compiler switches
#pragma GCC diagnostic pop

XAMPP Apache + MariaDB + PHP + Perl (X -any OS)

• After successful installation execute xampp-control.exe in XAMPP folder

• Start Apache and MySQL

• Open browser and in url type localhost or 127.0.0.1

• then you are welcomed with dashboard

By default your port is listing with 80.If you want you can change it to your desired port number in httpd.conf file.(If port 80 is already using with other app then you have to change it).

For example you changed port number 80 to 8090 then you can run as 'localhost:8090' or '127.0.0.1:8090'

That is exactly what you do with an advanced filter. If it's a one shot, you don't even need a macro, it is available in the Data menu.

Sheets("Sheet1").Range("A1:D17").AdvancedFilter Action:=xlFilterCopy, _
    CriteriaRange:=Sheets("Sheet1").Range("G1:G2"), CopyToRange:=Range("A1:D1") _
    , Unique:=False

Within your component, you can define an array of number (ES6) as described below:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill(0).map((x,i)=>i);
  }
}

See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.

You can then iterate over this array with ngFor:

@View({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Or shortly:

@View({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Hope it helps you, Thierry

Edit: Fixed the fill statement and template syntax.

The other solutions with window.location didn't work for me since they didn't make it refresh at all, so what I did was that I used an empty form to pass new and empty postdata to the same page. This is a way to do that based on this answer:

function refreshAndClearPost() {
    var form = document.createElement("form");
    form.method = "POST";
    form.action = location.href;
    form.style.display = "none";

    document.body.appendChild(form);
    form.submit();    //since the form is empty, it will pass empty postdata
    document.body.removeChild(form);
}

You can also see this error when selecting for a union where corresponding columns can be null.

select * from (select D.dept_no, D.nullable_comment
                  from dept D
       union
               select R.dept_no, NULL
                 from redundant_dept R
)

This apparently confuses the parser, a solution is to assign a column alias to the always null column.

select * from (select D.dept_no, D.comment
                  from dept D
       union
               select R.dept_no, NULL "nullable_comment"
                 from redundant_dept R
)

The alias does not have to be the same as the corresponding column, but the column heading in the result is driven by the first query from among the union members, so it's probably a good practice.

You can achieve that by using the reference to an angular DOM element as follows:

Here is the example in stackblitz

the component template:

<div class="other-content">
      Other content
      <button (click)="element.scrollIntoView({ behavior: 'smooth', block: 'center' })">
        Click to scroll
      </button>
    </div>
    <div id="content" #element>
      Some text to scroll
</div>

For me this error appeared immediatey after I changed the user's home directory by

sudo usermod -d var/www/html username

It can also happen because of lack of proper permission to authorized_key file in ~/.ssh. Make sure the permission of this file is 0600 and permission of ~/.ssh is 700.

You have to store the content as a fact:

- set_fact:
    string_to_echo: "{{ command_output.stdout }}"

As suggested by @The Berga You can add android:layoutDirection="rtl" but it's only available with API 17.
for dynamic implementation, here it goes

chkBox.setLayoutDirection(View.LAYOUT_DIRECTION_RTL);

Two steps, for example,

package main

import (
    "fmt"
    "strings"
)

func main() {
    s := strings.Split("127.0.0.1:5432", ":")
    ip, port := s[0], s[1]
    fmt.Println(ip, port)
}

Output:

127.0.0.1 5432

One step, for example,

package main

import (
    "fmt"
    "net"
)

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

Output:

127.0.0.1 5432 <nil>

In case it helps anyone... I was having a lot of trouble with setting up notifications using the support package when testing against newer an older API's. I was able to get them to work on the newer device but would get an error testing on the old device. What finally got it working for me was to delete all the imports related to the notification functions. In particular the NotificationCompat and the TaskStackBuilder. It seems that while setting up my code in the beginning the imports where added from the newer build and not from the support package. Then when I wanted to implement these items later in eclipse, I wasn't prompted to import them again. Hope that makes sense, and that it helps someone else out :)

None of above worked for me, so here is how y solved it, my class have only 1 method templated..

.h

class Model
{
    template <class T>
    void build(T* b, uint32_t number);
};

.cpp

#include "Model.h"
template <class T>
void Model::build(T* b, uint32_t number)
{
    //implementation
}

void TemporaryFunction()
{
    Model m;
    m.build<B1>(new B1(),1);
    m.build<B2>(new B2(), 1);
    m.build<B3>(new B3(), 1);
}

this avoid linker errors, and no need to call TemporaryFunction at all

PrincipalContext for browsing the AD is ridiculously slow (only use it for .ValidateCredentials, see below), use DirectoryEntry instead and .PropertiesToLoad() so you only pay for what you need.

Filters and syntax here: https://social.technet.microsoft.com/wiki/contents/articles/5392.active-directory-ldap-syntax-filters.aspx

Attributes here: https://docs.microsoft.com/en-us/windows/win32/adschema/attributes-all

using (var root = new DirectoryEntry($"LDAP://{Domain}"))

    using (var searcher = new DirectorySearcher(root))
    {
        // looking for a specific user
        searcher.Filter = $"(&(objectCategory=person)(objectClass=user)(sAMAccountName={username}))";
        // I only care about what groups the user is a memberOf
        searcher.PropertiesToLoad.Add("memberOf");

        // FYI, non-null results means the user was found
        var results = searcher.FindOne();

        var properties = results?.Properties;
        if (properties?.Contains("memberOf") == true)
        {
            // ... iterate over all the groups the user is a member of
        }
    }
}

Clean, simple, fast. No magic, no half-documented calls to .RefreshCache to grab the tokenGroups or to .Bind or .NativeObject in a try/catch to validate credentials.

For authenticating the user:

using (var context = new PrincipalContext(ContextType.Domain))
{
    return context.ValidateCredentials(username, password);

I think this is a good structure. And it is a nicely written blog explaining the mindset of these choices.

Including the header afxwin.h signalizes use of MFC. The following instructions (based on those on CodeProject.com) could help to get MFC code compiling:

1. Download and install the Windows Driver Kit.

2. Select menu Tools > Options… > Projects and Solutions > VC++ Directories.

3. In the drop-down menu Show directories for select Include files.

4. Add the following paths (replace $(WDK_directory) with the directory where you installed Windows Driver Kit in the first step):

   $(WDK_directory)\inc\mfc42
   $(WDK_directory)\inc\atl30
   

   

5. In the drop-down menu Show directories for select Library files and add (replace $(WDK_directory) like before):

   $(WDK_directory)\lib\mfc\i386
   $(WDK_directory)\lib\atl\i386
   

   

6. In the $(WDK_directory)\inc\mfc42\afxwin.inl file, edit the following lines (starting from 1033):

   _AFXWIN_INLINE CMenu::operator==(const CMenu& menu) const
       { return ((HMENU) menu) == m_hMenu; }
   _AFXWIN_INLINE CMenu::operator!=(const CMenu& menu) const
       { return ((HMENU) menu) != m_hMenu; }
   

   to

   _AFXWIN_INLINE BOOL CMenu::operator==(const CMenu& menu) const
       { return ((HMENU) menu) == m_hMenu; }
   _AFXWIN_INLINE BOOL CMenu::operator!=(const CMenu& menu) const
       { return ((HMENU) menu) != m_hMenu; }
   

   In other words, add BOOL after _AFXWIN_INLINE.

Product Version may be preferred if you're using versioning via GitVersion or other versioning software.

To get this from within your class library you can call System.Diagnostics.FileVersionInfo.ProductVersion:

using System.Diagnostics;
using System.Reflection;

//...

var assemblyLocation = Assembly.GetExecutingAssembly().Location;
var productVersion = FileVersionInfo.GetVersionInfo(assemblyLocation).ProductVersion

man ssh gives me this options would could be useful.

-i identity_file Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for pro- tocol version 2. Identity files may also be specified on a per- host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in config- uration files).

So you could create an alias in your bash config with something like

alias ssh="ssh -i /path/to/private_key"

I haven't looked into a ssh configuration file, but like the -i option this too could be aliased

-F configfile Specifies an alternative per-user configuration file. If a configuration file is given on the command line, the system-wide configuration file (/etc/ssh/ssh_config) will be ignored. The default for the per-user configuration file is ~/.ssh/config.

                <li><a <?php echo ($page == "yourfilename") ? "class='active'" : ""; ?> href="newarticle.php"><span>New Articles</span></a></li>

An alternate way is to construct a view which is then queried just like a table. In many database managers using a view can result in better performance.

CREATE VIEW xyz SELECT q.question, a.alternative  
   FROM tbl_question AS q, tbl_alternative AS a
  WHERE q.categoryid = a.categoryid 
    AND q._id = a.questionid;

This is from memory so there may be some syntactic issues. http://www.sqlite.org/lang_createview.html

I mention this approach because then you can use SQLiteQueryBuilder with the view as you implied that it was preferred.

This works on Laravel 5:

{!!strlen($post->content) > 200 ? substr($post->content,0,200) : $post->content!!}

This can replace the MaxLength and the MinLength

[StringLength(40, MinimumLength = 10 , ErrorMessage = "Password cannot be longer than 40 characters and less than 10 characters")]

My final solution

class DynamicModeTabLayout : TabLayout {

    constructor(context: Context?) : super(context)
    constructor(context: Context?, attrs: AttributeSet?) : super(context, attrs)
    constructor(context: Context?, attrs: AttributeSet?, defStyleAttr: Int) : super(context, attrs, defStyleAttr)

    override fun setupWithViewPager(viewPager: ViewPager?) {
        super.setupWithViewPager(viewPager)

        val view = getChildAt(0) ?: return
        view.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED)
        val size = view.measuredWidth

        if (size > measuredWidth) {
            tabMode = MODE_SCROLLABLE
            tabGravity = GRAVITY_CENTER
        } else {
            tabMode = MODE_FIXED
            tabGravity = GRAVITY_FILL
        }
    }
}

A simple alternative to using a custom UserType is to construct a new java.util.Date in the setter for the date property in your persisted bean, eg:

import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.Column;

@Entity
public class Purchase {

    private Date date;

    @Column
    public Date getDate() {
        return this.date;
    }

    public void setDate(Date date) {
        // force java.sql.Timestamp to be set as a java.util.Date
        this.date = new Date(date.getTime());
    }

}

C#

using System.Text.RegularExpressions;
...    
Regex.Match(
    input: "Check This String",
    pattern: "Regex Pattern",
    options: RegexOptions.IgnoreCase)

specifically: options: RegexOptions.IgnoreCase

Strong typing probably means that variables have a well-defined type and that there are strict rules about combining variables of different types in expressions. For example, if A is an integer and B is a float, then the strict rule about A+B might be that A is cast to a float and the result returned as a float. If A is an integer and B is a string, then the strict rule might be that A+B is not valid.

Static typing probably means that types are assigned at compile time (or its equivalent for non-compiled languages) and cannot change during program execution.

Note that these classifications are not mutually exclusive, indeed I would expect them to occur together frequently. Many strongly-typed languages are also statically-typed.

And note that when I use the word 'probably' it is because there are no universally accepted definitions of these terms. As you will already have seen from the answers so far.

I met the same problem.
First delete build folder from project location (You can access it via android studio or using explorer), then build the project.

Possibly you could use jni4net - opensource bridge instead ? Or list of other options I know.
