For JavaFX

import javafx.scene.paint.Color;

.

Color whiteColor = Color.valueOf("#ffffff");

Yes, there is a way to do this. You could use a pseudo-element after to position a block on top of your background image. Something like this: http://jsfiddle.net/Pevara/N2U6B/

The css for the :after looks like this:

#the-div:hover:after {
    content: ' ';
    position: absolute;
    left: 0;
    right: 0;
    top: 0;
    bottom: 0;
    background-color: rgba(0,0,0,.5);
}

edit:
When you want to apply this to a non-empty element, and just get the overlay on the background, you can do so by applying a positive z-index to the element, and a negative one to the :after. Something like this:

#the-div {
    ...
    z-index: 1;
}
#the-div:hover:after {
    ...
    z-index: -1;
}

And the updated fiddle: http://jsfiddle.net/N2U6B/255/

Maybe this is more along the lines of what you are missing:

If you are coming from a C++ like viewpoint, delegates takes a little getting used to - but basically 'they just work'.

The way it works is that you set some object that you wrote as the delegate to NSWindow, but your object only has implementations (methods) for one or a few of the many possible delegate methods. So something happens, and NSWindow wants to call your object - it just uses Objective-c's respondsToSelector method to determine if your object wants that method called, and then calls it. This is how objective-c works - methods are looked up on demand.

It is totally trivial to do this with your own objects, there is nothing special going on, you could for instance have an NSArray of 27 objects, all different kinds of objects, only 18 some of them having the method -(void)setToBue; The other 9 don't. So to call setToBlue on all of 18 that need it done, something like this:

for (id anObject in myArray)
{
  if ([anObject respondsToSelector:@selector(@"setToBlue")])
     [anObject setToBlue]; 
}

The other thing about delegates is that they are not retained, so you always have to set the delegate to nil in your MyClass dealloc method.

Bottom Line

Your code has retrieved data (entities) via entity-framework with lazy-loading enabled and after the DbContext has been disposed, your code is referencing properties (related/relationship/navigation entities) that was not explicitly requested.

More Specifically

The InvalidOperationException with this message always means the same thing: you are requesting data (entities) from entity-framework after the DbContext has been disposed.

A simple case:

(these classes will be used for all examples in this answer, and assume all navigation properties have been configured correctly and have associated tables in the database)

public class Person
{
  public int Id { get; set; }
  public string name { get; set; }
  public int? PetId { get; set; }
  public Pet Pet { get; set; }
}

public class Pet 
{
  public string name { get; set; }
}

using (var db = new dbContext())
{
  var person = db.Persons.FirstOrDefaultAsync(p => p.id == 1);
}

Console.WriteLine(person.Pet.Name);

The last line will throw the InvalidOperationException because the dbContext has not disabled lazy-loading and the code is accessing the Pet navigation property after the Context has been disposed by the using statement.

Debugging

How do you find the source of this exception? Apart from looking at the exception itself, which will be thrown exactly at the location where it occurs, the general rules of debugging in Visual Studio apply: place strategic breakpoints and inspect your variables, either by hovering the mouse over their names, opening a (Quick)Watch window or using the various debugging panels like Locals and Autos.

If you want to find out where the reference is or isn't set, right-click its name and select "Find All References". You can then place a breakpoint at every location that requests data, and run your program with the debugger attached. Every time the debugger breaks on such a breakpoint, you need to determine whether your navigation property should have been populated or if the data requested is necessary.

Ways to Avoid

Disable Lazy-Loading

public class MyDbContext : DbContext
{
  public MyDbContext()
  {
    this.Configuration.LazyLoadingEnabled = false;
  }
}

Pros: Instead of throwing the InvalidOperationException the property will be null. Accessing properties of null or attempting to change the properties of this property will throw a NullReferenceException.

How to explicitly request the object when needed:

using (var db = new dbContext())
{
  var person = db.Persons
    .Include(p => p.Pet)
    .FirstOrDefaultAsync(p => p.id == 1);
}
Console.WriteLine(person.Pet.Name);  // No Exception Thrown

In the previous example, Entity Framework will materialize the Pet in addition to the Person. This can be advantageous because it’s a single call the the database. (However, there can also be huge performance problems depending on the number of returned results and the number of navigation properties requested, in this instance, there would be no performance penalty because both instances are only a single record and a single join).

or

using (var db = new dbContext())
{
  var person = db.Persons.FirstOrDefaultAsync(p => p.id == 1);

  var pet = db.Pets.FirstOrDefaultAsync(p => p.id == person.PetId);
}
Console.WriteLine(person.Pet.Name);  // No Exception Thrown

In the previous example, Entity Framework will materialize the Pet independently of the Person by making an additional call to the database. By default, Entity Framework tracks objects it has retrieved from the database and if it finds navigation properties that match it will auto-magically populate these entities. In this instance because the PetId on the Person object matches the Pet.Id, Entity Framework will assign the Person.Pet to the Pet value retrieved, before the value is assigned to the pet variable.

I always recommend this approach as it forces programmers to understand when and how code is request data via Entity Framework. When code throws a null reference exception on a property of an entity, you can almost always be sure you have not explicitly requested that data.

You're using integer division.

Try 7.0/10 instead.

If you want to programmatically access the inventory entries to include them in a task for example. You can refer to it like this:

{{ hostvars.tomcat }}

This returns you a structure with all variables related with that host. If you want just an IP address (or hostname), you can refer to it like this:

{{ hostvars.jboss5.ansible_ssh_host }}

Here is a list of variables which you can refer to: click. Moreover, you can declare a variable and set it with for example result of some step in a playbook.

- name: Change owner and group of some file
  file: path=/tmp/my-file owner=new-owner group=new-group
  register: chown_result

Then if you play this step on tomcat, you can access it from jboss5 like this:

- name: Print out the result of chown
  debug: msg="{{ hostvars.tomcat.chown_result }}"

Propose a much more readable solution (in Python, but applies to any regex):

def url_path_to_dict(path):
    pattern = (r'^'
               r'((?P<schema>.+?)://)?'
               r'((?P<user>.+?)(:(?P<password>.*?))?@)?'
               r'(?P<host>.*?)'
               r'(:(?P<port>\d+?))?'
               r'(?P<path>/.*?)?'
               r'(?P<query>[?].*?)?'
               r'$'
               )
    regex = re.compile(pattern)
    m = regex.match(path)
    d = m.groupdict() if m is not None else None

    return d

def main():
    print url_path_to_dict('http://example.example.com/example/example/example.html')

Prints:

{
'host': 'example.example.com', 
'user': None, 
'path': '/example/example/example.html', 
'query': None, 
'password': None, 
'port': None, 
'schema': 'http'
}

Type unset HOST in your terminal.

UPDATE: See JSFiddle

Other than the given answers, in the case that you have something like this:

<div id="test">
    <input type="file" name="file0" onchange="changed()">
</div>
<script type="text/javascript">
    var isAllowed = true;
    function changed()
    {
        if (isAllowed)
        {
            var tmpHTML = $('#test').html();
            tmpHTML += "<input type=\"file\" name=\"file1\" onchange=\"changed()\">";
            $('#test').html(tmpHTML);
            isAllowed = false;
        }
    }
</script>

meaning that you want to automatically add one more file upload if any files were uploaded, the mentioned code will not work, because after the file is uploaded, the first file-upload element will be recreated and therefore the uploaded file will be wiped from it. You should use .append() instead:

    function changed()
    {
        if (isAllowed)
        {
            var tmpHTML = "<input type=\"file\" name=\"file1\" onchange=\"changed()\">";
            $('#test').append(tmpHTML);
            isAllowed = false;
        }
    }

Tie::File is what you need:

Synopsis

# This file documents Tie::File version 0.98
use Tie::File;

tie @array, 'Tie::File', 'filename' or die ...;

$array[13] = 'blah';     # line 13 of the file is now 'blah'
print $array[42];        # display line 42 of the file

$n_recs = @array;        # how many records are in the file?
$#array -= 2;            # chop two records off the end


for (@array) {
  s/PERL/Perl/g;         # Replace PERL with Perl everywhere in the file
}

# These are just like regular push, pop, unshift, shift, and splice
# Except that they modify the file in the way you would expect

push @array, new recs...;
my $r1 = pop @array;
unshift @array, new recs...;
my $r2 = shift @array;
@old_recs = splice @array, 3, 7, new recs...;

untie @array;            # all finished

That CSS goes from this file "tab-focus.less" in mixins folder (it could be difficult to find, because mixins are not shown at chrome dev-tools). So you should edit this:

// WebKit-style focus 

.tab-focus() {
      // Default
      outline: thin dotted;
      // WebKit
      outline: 5px auto -webkit-focus-ring-color;
      outline-offset: -2px;
    }

For running console apps you should set up some additional tools:

• ASP.NET 5; in Powershell: &{$Branch='dev';iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1'))}
• Node.js including package manager npm.
• The rest of required tools including Yeoman yo: npm install -g yo grunt-cli generator-aspnet bower
• You should also invoke .NET Version Manager: c:\Users\Username\.dnx\bin\dnvm.cmd upgrade -u

Then you can use yo as wizard for Console Application: yo aspnet Choose name and project type. After that go to created folder cd ./MyNewConsoleApp/ and run dnu restore

To execute your program just type >run in Command Palette (Ctrl+Shift+P), or execute dnx . run in shell from the directory of your project.

Easier option is to use ./eclipse -clean

You cant add add items in string array more than its size, i'll suggest you to use ArrayList you can add items dynamically at run time in arrayList if you feel any problem you can freely ask

I ran into the same issue (exact error message) and after digging for a couple of hours, I found that the content header needs to be set to application/javascript instead of the application/json that I had. After changing that, it now works.

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:

x = ["0", "1", "2"] 
y = int(x[0]) #accessing the zeroth element

If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:

x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)

If your list elements are not strings, you'll have to convert them to strings before using str.join:

x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)

Also, as stated above, make sure that you're not returning a nested list.

Here simple example to create pandas dataframe by using numpy array.

import numpy as np

# create an array 
var1  = np.arange(start=1, stop=21, step=1).reshape(-1)
var2 = np.random.rand(20,1).reshape(-1)

dataset.head()

A template class is like a macro, only a whole lot less evil.

Think of a template as a macro. The parameters to the template get substituted into a class (or function) definition, when you define a class (or function) using a template.

The difference is that the parameters have "types" and values passed are checked during compilation, like parameters to functions. The types valid are your regular C++ types, like int and char. When you instantiate a template class, you pass a value of the type you specified, and in a new copy of the template class definition this value gets substituted in wherever the parameter name was in the original definition. Just like a macro.

You can also use the "class" or "typename" types for parameters (they're really the same). With a parameter of one of these types, you may pass a type name instead of a value. Just like before, everywhere the parameter name was in the template class definition, as soon as you create a new instance, becomes whatever type you pass. This is the most common use for a template class; Everybody that knows anything about C++ templates knows how to do this.

Consider this template class example code:

#include <cstdio>
template <int I>
class foo
{
  void print()
  {
    printf("%i", I);
  }
};

int main()
{
  foo<26> f;
  f.print();
  return 0;
}

It's functionally the same as this macro-using code:

#include <cstdio>
#define MAKE_A_FOO(I) class foo_##I \
{ \
  void print() \
  { \
    printf("%i", I); \
  } \
};

MAKE_A_FOO(26)

int main()
{
  foo_26 f;
  f.print();
  return 0;
}

Of course, the template version is a billion times safer and more flexible.

I found a way to find out how your provisioning profile is named. Select the profile that you want in the code sign section in the build settings, then open the selection view again and click on "other" at the bottom. Then occur a view with the naming of the current selected provisioning profile.

You can now find the profile file on the path:

~/Library/MobileDevice/Provisioning Profiles

Update:

For Terminal:

cd ~/Library/MobileDevice/Provisioning\ Profiles

Many of these answers seem a little complicated. In Python 3.x you simply do this:

print(<expr>, <expr>, ..., <expr>, end=" ")

The default value of end is "\n". We are simply changing it to a space or you can also use end="" (no space) to do what printf normally does.

I don't know why everybody is answering this question in context of .NET. The question was a general one and didn't mention .NET anywhere.

Well, the major differences are:

EXE

1. An exe always runs in its own address space i.e., It is a separate process.
2. The purpose of an EXE is to launch a separate application of its own.

DLL

1. A dll always needs a host exe to run. i.e., it can never run in its own address space.
2. The purpose of a DLL is to have a collection of methods/classes which can be re-used from some other application.
3. DLL is Microsoft's implementation of a shared library.

The file format of DLL and exe is essentially the same. Windows recognizes the difference between DLL and EXE through PE Header in the file. For details of PE Header, You can have a look at this Article on MSDN

You have set #slider as absolute, which means that it "is positioned relative to the nearest positioned ancestor" (confusing, right?). Meanwhile, #content div is placed relative, which means "relative to its normal position". So the position of the 2 divs is not related.

You can read about CSS positioning here

If you set both to relative, the divs will be one after the other, as shown here:

#slider {
    position:relative;
    left:0;
    height:400px;

    border-style:solid;
    border-width:5px;
}
#slider img {

}

#content {

I had no idea what file was having the lock so what I did to get out of this issue was:

1. Went to the highest level folder
2. Click clean-up and also ticked from the cleaning-up methods --> Break locks

This worked for me.

If john were an optional var (declared thusly)

var john: Person?

then it would be possible for john to have no value (in ObjC parlance, nil value)

The exclamation point basically tells the compiler "I know this has a value, you don't need to test for it". If you didn't want to use it, you could conditionally test for it:

if let otherPerson = john {
    otherPerson.apartment = number73
}

The interior of this will only evaluate if john has a value.

If you don't want to repeat the list twice (as per @J W's answer), then put the updates in a table variable and use a JOIN in the UPDATE:

declare @ToDo table (FromName varchar(10), ToName varchar(10))
insert into @ToDo(FromName,ToName) values
 ('AAA','BBB'),
 ('CCC','DDD'),
 ('EEE','FFF')

update ts set LastName = ToName
from dbo.TestStudents ts
       inner join
     @ToDo t
       on
         ts.LastName = t.FromName

I was getting this error, when I was using the same variable for json string and parsed json:

var json = '{"1":{"url":"somesite1","poster":"1.png","title":"site title"},"2":{"url":"somesite2","poster":"2.jpg","title":"site 2 title"}}'

function usingjson(){
    var json = JSON.parse(json);
}

I changed function to:

function usingjson(){
    var j = JSON.parse(json);
}

Now this error went away.

What helped me, was right clicking the 'IISExpress' icon, 'Show All applications'. Then selecting the website and I saw which aplicationhost.config it uses, and the the correction went perfectly.

I would use SWFUpload or Uploadify. They need Flash but do everything you want without troubles.

Any <input type="file"> based workaround that tries to trigger the "open file" dialog by means other than clicking on the actual control could be removed from browsers for security reasons at any time. (I think in the current versions of FF and IE, it is not possible any more to trigger that event programmatically.)

you can use toggleClass() to toggle class it is really handy.

Quite a few utility libraries such as YourJS offer functions for determining if something is an array or if something is an integer or a lot of other types as well. YourJS defines isInt by checking if the value is a number and then if it is divisible by 1:

function isInt(x) {
  return typeOf(x, 'Number') && x % 1 == 0;
}

The above snippet was taken from this YourJS snippet and thusly only works because typeOf is defined by the library. You can download a minimalistic version of YourJS which mainly only has type checking functions such as typeOf(), isInt() and isArray(): http://yourjs.com/snippets/build/34,2

From Wikipedia (granularity):

Granularity is the extent to which a system is broken down into small parts, either the system itself or its description or observation. It is the extent to which a larger entity is subdivided. For example, a yard broken into inches has finer granularity than a yard broken into feet.

Coarse-grained systems consist of fewer, larger components than fine-grained systems; a coarse-grained description of a system regards large subcomponents while a fine-grained description regards smaller components of which the larger ones are composed.

In java, string objects are immutable. Immutable simply means unmodifiable or unchangeable.

Once string object is created its data or state can't be changed but a new string object is created.

Here is the analysis in the book Data Structures and Algorithm Analysis in C by Mark Allen Weiss (second edition, 2.4.4):

Euclid's algorithm works by continually computing remainders until 0 is reached. The last nonzero remainder is the answer.

Here is the code:

unsigned int Gcd(unsigned int M, unsigned int N)
{

    unsigned int Rem;
    while (N > 0) {
        Rem = M % N;
        M = N;
        N = Rem;
    }
    Return M;
}

Here is a THEOREM that we are going to use:

If M > N, then M mod N < M/2.

PROOF:

There are two cases. If N <= M/2, then since the remainder is smaller than N, the theorem is true for this case. The other case is N > M/2. But then N goes into M once with a remainder M - N < M/2, proving the theorem.

So, we can make the following inference:

Variables    M      N      Rem

initial      M      N      M%N

1 iteration  N     M%N    N%(M%N)

2 iterations M%N  N%(M%N) (M%N)%(N%(M%N)) < (M%N)/2

So, after two iterations, the remainder is at most half of its original value. This would show that the number of iterations is at most 2logN = O(logN).

Note that, the algorithm computes Gcd(M,N), assuming M >= N.(If N > M, the first iteration of the loop swaps them.)

Both stored procedures and functions are named blocks that reside in the database and can be executed as and when required.

The major differences are:

1. A stored procedure can optionally return values using out parameters, but can also be written in a manner without returning a value. But, a function must return a value.

2. A stored procedure cannot be used in a SELECT statement whereas a function can be used in a SELECT statement.

Practically speaking, I would go for a stored procedure for a specific group of requirements and a function for a common requirement that could be shared across multiple scenarios. For example: comparing between two strings, or trimming them or taking the last portion, if we have a function for that, we could globally use it for any application that we have.

have at look at the static methods DateTime.Parse() and DateTime.TryParse(). They will allow you to pass in your date string and a format string, and get a DateTime object in return.

What you have can be written easier. Instead of:

#include<iostream>
int main()
{
    std::cout<<"Hello, World!\n";
    return 0;
}

write

#include<iostream>
int main()
{
    std::cout<<"Hello, World!\n";
    system("PAUSE");
    return 0;
}

The system function executes anything you give it as if it was written in the command prompt. It suspends execution of your program while the command is executing so you can do anything with it, you can even compile programs from your cpp program.

If you are using individual jquery files or a custom jquery download either way make sure you also have jquery.ui.position.js added to your page.

Someone with more reputation can copy this into the main answer:

• Change Tracking. Allows you to get info on what changes happened to which rows since a specific version.
• Change Data Capture. Allows all changes to be captured and queried. (Enterprise)

It should be :

public async Task<ActionResult> GetSomeJsonData()
{
    var model = // ... get data or build model etc.

    return Json(new { Data = model }, JsonRequestBehavior.AllowGet); 
}

or more simply:

return Json(model, JsonRequestBehavior.AllowGet); 

I did notice that you are calling GetResources() from another ActionResult which wont work. If you are looking to get JSON back, you should be calling GetResources() from ajax directly...

Something like

create or replace procedure my_proc( p_rc OUT SYS_REFCURSOR )
as
begin
  open p_rc
   for select 1 col1
         from dual;
end;
/

variable rc refcursor;
exec my_proc( :rc );
print rc;

will work in SQL*Plus or SQL Developer. I don't have any experience with Embarcardero Rapid XE2 so I have no idea whether it supports SQL*Plus commands like this.

I had exactly the same problem.

After a recheck of my PATH, I realized I installed both Mingw (64 bit) and Cygwin (32 bit). The problem is that both Mingw and Cygwin have g++.

By deactivating the path of Cygwin, the error disappeared.

Extract from the oficial docs:

Requires that the parent form is validated, that is, $( "form" ).validate() is called first

First way: JOIN:

get people with multiple countries:

SELECT u1.user_id 
FROM users u1
JOIN users u2
on u1.user_id  = u2.user_id 
AND u1.ancestry <> u2.ancestry

Get people from 2 specific countries:

SELECT u1.user_id 
FROM users u1
JOIN users u2
on u1.user_id  = u2.user_id 
WHERE u1.ancestry = 'Germany'
AND u2.ancestry = 'France'

For 3 countries... join three times. To only get the result(s) once, distinct.

Second way: GROUP BY

This will get users which have 3 lines (having...count) and then you specify which lines are permitted. Note that if you don't have a UNIQUE KEY on (user_id, ancestry), a user with 'id, england' that appears 3 times will also match... so it depends on your table structure and/or data.

SELECT user_id 
FROM users u1
WHERE ancestry = 'Germany'
OR ancestry = 'France'
OR ancestry = 'England'
GROUP BY user_id
HAVING count(DISTINCT ancestry) = 3

Here is a link to a shorter and to the point description: http://www.granneman.com/webdev/editors/sublime-text/packages/how-to-install-and-use-package-control/

The steps are:

1. Install package control.
2. Go to http://wbond.net/sublime_packages/package_control/installation and grab the install code.
3. In Sublime Text 2 open the console (Ctrl+`) and paste the code.
4. Restart Sublime Text 2.
5. Open command palette via Command+Shift+P (Mac OSX) or Ctrl+Shift+P (Windows).
6. Start typing Package Control and choose the package you are looking for.

Actually, em.flush(), do more than just sends the cached SQL commands. It tries to synchronize the persistence context to the underlying database. It can cause a lot of time consumption on your processes if your cache contains collections to be synchronized.

Caution on using it.

If it's "all smushed together" you can often give the ol' "view source code" a try. Sometimes the dumps, messages and exceptions seem like they're just one long string when it turns out that the line breaks simply don't show. Especially XML trees.

Alternatively, I've once created a small little tool called InteractiveVarDump for this very purpose. It certainly has its limits but it can also be very convenient sometimes. Even though it was designed with PHP 5 in mind.

In brief

This kind of a setup is simple and elegant :

env.json

{
  "development": {
      "facebook_app_id": "facebook_dummy_dev_app_id",
      "facebook_app_secret": "facebook_dummy_dev_app_secret",
  }, 
  "production": {
      "facebook_app_id": "facebook_dummy_prod_app_id",
      "facebook_app_secret": "facebook_dummy_prod_app_secret",
  }
}

common.js

var env = require('env.json');

exports.config = function() {
  var node_env = process.env.NODE_ENV || 'development';
  return env[node_env];
};

app.js

var common = require('./routes/common')
var config = common.config();

var facebook_app_id = config.facebook_app_id;
// do something with facebook_app_id

To run in production mode : $ NODE_ENV=production node app.js

BigDecimal is the best data type to use for currency.

There are a whole lot of containers for currency, but they all use BigDecimal as the underlying data type. You won't go wrong with BigDecimal, probably using BigDecimal.ROUND_HALF_EVEN rounding.

You can only view the log on a local repository, however that can include the fetched branches of all remotes you have set-up.

So, if you clone a repo...

git clone git@gitserver:folder/repo.git

This will default to origin/master.

You can add a remote to this repo, other than origin let's add production. From within the local clone folder:

git remote add production git@production-server:folder/repo.git

If we ever want to see the log of production we will need to do:

git fetch --all 

This fetches from ALL remotes (default fetch without --all would fetch just from origin)

After fetching we can look at the log on the production remote, you'll have to specify the branch too.

git log production/master

All options will work as they do with log on local branches.

0x means the number is hexadecimal, or base 16.

0x10 is 16.

You confuse how browsers renders the elements when there are floating elements. If one block element is floating (your inner div in your case), other block elements will ignore it because browser removes floating elements from the normal flow of the web page. Then, because the floated div has been removed from the normal flow, the outside div is filled in, like the inner div isn't there. However, inline elements (images, links, text, blackquotes) will respect the boundaries of the floating element. If you introduce text in the outside div, the text will place arround de inner div.

In other words, block elements (headers, paragraphs, divs, etc) ignore floating elements and fill in, and inline elements (images, links, text, etc) respect boundaries of floating elements.

An fiddle example here

<body>
    <div style="float:right; background-color:blue;width:200px;min-height:400px;margin-right:20px">
           floating element
    </div>
    <h1 style="background-color:red;"> this is a big header</h1>
    <p style="background-color:green"> this is a parragraph with text and a big image. The text places arrounds the floating element. Because of the image is wider than space between paragrah and floating element places down the floating element. Try to make wider the viewport and see what happens :D

The only subquery appears to be this - try adding a ROWNUM limit to the where to be sure:

(SELECT C.I_WORKDATE
         FROM T_COMPENSATION C
         WHERE C.I_COMPENSATEDDATE = A.I_REQDATE AND ROWNUM <= 1
         AND C.I_EMPID = A.I_EMPID)

You do need to investigate why this isn't unique, however - e.g. the employee might have had more than one C.I_COMPENSATEDDATE on the matched date.

For performance reasons, you should also see if the lookup subquery can be rearranged into an inner / left join, i.e.

 SELECT 
    ...
    REPLACE(TO_CHAR(C.I_WORKDATE, 'DD-Mon-YYYY'),
            ' ',
            '') AS WORKDATE,
    ...
 INNER JOIN T_EMPLOYEE_MS E
    ...
     LEFT OUTER JOIN T_COMPENSATION C
          ON C.I_COMPENSATEDDATE = A.I_REQDATE
          AND C.I_EMPID = A.I_EMPID
    ...

For CodeIgniter 4, you can use the built-in API Response Trait

Here's sample code for reference:

<?php namespace App\Controllers;

use CodeIgniter\API\ResponseTrait;

class Home extends BaseController
{
    use ResponseTrait;

    public function index()
    {
        $data = [
            'data' => 'value1',
            'data2' => 'value2',
        ];

        return $this->respond($data);
    }
}

I have a Mac, but luckily this should work the same way:

pip is a command-line thing. You don't run it in python.

For example, on my Mac, I just say:

$pip install somelib

pretty easy!

To rename the package name in Android studio, Click on the setting icon in the project section and untick the Compact empty Middle Packages, after that the package will split into multiple folder names, then right click on the folder you need to change the name, click on refactor-> Rename-> Type the name you want to change in -> Refactor -> Refactor Directory, then import R.java file in the whole project. Working for me.

Your project should almost always use the past tense. In any case, the project should always use the same tense for consistency and clarity.

I understand some of the other arguments arguing to use the present tense, but they usually don't apply. The following bullet points are common arguments for writing in the present tense, and my response.

• Writing in the present tense tells someone what applying the commit will do, rather than what you did.

This is the most correct reason one would want to use the present tense, but only with the right style of project. This manner of thinking considers all commits as optional improvements or features, and you are free to decide which commits to keep and which to reject in your particular repository.

This argument works if you are dealing with a truly distributed project. If you are dealing with a distributed project, you are probably working on an open source project. And it is probably a very large project if it is really distributed. In fact, it's probably either the Linux kernel or Git. Since Linux is likely what caused Git to spread and gain in popularity, it's easy to understand why people would consider its style the authority. Yes, the style makes sense with those two projects. Or, in general, it works with large, open source, distributed projects.

That being said, most projects in source control do not work like this. It is usually incorrect for most repositories. It's a modern way of thinking about a commits: Subversion (SVN) and CVS repositories could barely support this style of repository check-ins. Usually an integration branch handled filtering bad check-ins, but those generally weren't considered "optional" or "nice-to-have features".

In most scenarios, when you are making commits to a source repository, you are writing a journal entry which describes what changed with this update, to make it easier for others in the future to understand why a change was made. It generally isn't an optional change - other people in the project are required to either merge or rebase on it. You don't write a diary entry such as "Dear diary, today I meet a boy and he says hello to me.", but instead you write "I met a boy and he said hello to me."

Finally, for such non-distributed projects, 99.99% of the time a person will be reading a commit message is for reading history - history is read in the past tense. 0.01% of the time it will be deciding whether or not they should apply this commit or integrate it into their branch/repository.

• Consistency. That's how it is in many projects (including git itself). Also git tools that generate commits (like git merge or git revert) do it.

No, I guarantee you that the majority of projects ever logged in a version control system have had their history in the past tense (I don't have references, but it's probably right, considering the present tense argument is new since Git). "Revision" messages or commit messages in the present tense only started making sense in truly distributed projects - see the first point above.

• People not only read history to know "what happened to this codebase", but also to answer questions like "what happens when I cherry-pick this commit", or "what kind of new things will happen to my code base because of these commits I may or may not merge in the future".

See the first point. 99.99% of the time a person will be reading a commit message is for reading history - history is read in the past tense. 0.01% of the time it will be deciding whether or not they should apply this commit or integrate it into their branch/repository. 99.99% beats 0.01%.

• It's usually shorter

I've never seen a good argument that says use improper tense/grammar because it's shorter. You'll probably only save 3 characters on average for a standard 50 character message. That being said, the present tense on average will probably be a few characters shorter.

• You can name commits more consistently with titles of tickets in your issue/feature tracker (which don't use past tense, although sometimes future)

Tickets are written as either something that is currently happening (e.g. the app is showing the wrong behavior when I click this button), or something that needs to be done in the future (e.g. the text will need a review by the editor).

History (i.e. commit messages) is written as something that was done in the past (e.g. the problem was fixed).

In my case I had to wait for a user interaction, so I set a click or touchend listener.

const isMobile = navigator.maxTouchPoints || "ontouchstart" in document.documentElement;

function play(){
    audioEl.play()
}


document.body.addEventListener(isMobile ? "touchend" : "click", play, { once: true });

There are two ways for specifying parameters in C. One is using an identifier list, and the other is using a parameter type list. The identifier list can be omitted, but the type list can not. So, to say that one function takes no arguments in a function definition you do this with an (omitted) identifier list

void f() {
    /* do something ... */
}

And this with a parameter type list:

void f(void) {
    /* do something ... */
}

If in a parameter type list the only one parameter type is void (it must have no name then), then that means the function takes no arguments. But those two ways of defining a function have a difference regarding what they declare.

Identifier lists

The first defines that the function takes a specific number of arguments, but neither the count is communicated nor the types of what is needed - as with all function declarations that use identifier lists. So the caller has to know the types and the count precisely before-hand. So if the caller calls the function giving it some argument, the behavior is undefined. The stack could become corrupted for example, because the called function expects a different layout when it gains control.

Using identifier lists in function parameters is deprecated. It was used in old days and is still present in lots of production code. They can cause severe danger because of those argument promotions (if the promoted argument type do not match the parameter type of the function definition, behavior is undefined either!) and are much less safe, of course. So always use the void thingy for functions without parameters, in both only-declarations and definitions of functions.

Parameter type list

The second one defines that the function takes zero arguments and also communicates that - like with all cases where the function is declared using a parameter type list, which is called a prototype. If the caller calls the function and gives it some argument, that is an error and the compiler spits out an appropriate error.

The second way of declaring a function has plenty of benefits. One of course is that amount and types of parameters are checked. Another difference is that because the compiler knows the parameter types, it can apply implicit conversions of the arguments to the type of the parameters. If no parameter type list is present, that can't be done, and arguments are converted to promoted types (that is called the default argument promotion). char will become int, for example, while float will become double.

Composite type for functions

By the way, if a file contains both an omitted identifier list and a parameter type list, the parameter type list "wins". The type of the function at the end contains a prototype:

void f();
void f(int a) {
    printf("%d", a);
}

// f has now a prototype. 

That is because both declarations do not say anything contradictory. The second, however, had something to say in addition. Which is that one argument is accepted. The same can be done in reverse

void f(a) 
  int a;
{ 
    printf("%d", a);
}

void f(int);

The first defines a function using an identifier list, while the second then provides a prototype for it, using a declaration containing a parameter type list.

@AlexCuse I wanted to add this as comment to your answer but gave up after making multiple failed attempt to add newlines in comments.

That said, t1ID is unique in table_1 but that doesn't makes it unique in INFO table as well.

For example:

Table_1 has:
Id Field
1 A
2 B

Table_2 has:
Id Field
1 X
2 Y

INFO then can have:
t1ID t2ID field
1 1 some
1 2 data
2 1 in-each
2 2 row

So in INFO table to uniquely identify a row you need both t1ID and t2ID

If you don't want to lose the columns you shift past the end of your dataframe, simply append the required number first:

    offset = 5
    DF = DF.append([np.nan for x in range(offset)])
    DF = DF.shift(periods=offset)
    DF = DF.reset_index() #Only works if sequential index

I'm perhaps a bit of a perfectionist; I don't really like the ForMember(..., x => x.Ignore()) syntax. It's a little thing, but it it matters to me. I wrote this extension method to make it a bit nicer:

public static IMappingExpression<TSource, TDestination> Ignore<TSource, TDestination>(
    this IMappingExpression<TSource, TDestination> map,
    Expression<Func<TDestination, object>> selector)
{
    map.ForMember(selector, config => config.Ignore());
    return map;
}

It can be used like so:

Mapper.CreateMap<JsonRecord, DatabaseRecord>()
        .Ignore(record => record.Field)
        .Ignore(record => record.AnotherField)
        .Ignore(record => record.Etc);

You could also rewrite it to work with params, but I don't like the look of a method with loads of lambdas.

One way, making the preprocessor do the work. It also ensures your enums and strings are in sync.

#define FOREACH_FRUIT(FRUIT) \
        FRUIT(apple)   \
        FRUIT(orange)  \
        FRUIT(grape)   \
        FRUIT(banana)  \

#define GENERATE_ENUM(ENUM) ENUM,
#define GENERATE_STRING(STRING) #STRING,

enum FRUIT_ENUM {
    FOREACH_FRUIT(GENERATE_ENUM)
};

static const char *FRUIT_STRING[] = {
    FOREACH_FRUIT(GENERATE_STRING)
};

After the preprocessor gets done, you'll have:

enum FRUIT_ENUM {
    apple, orange, grape, banana,
};

static const char *FRUIT_STRING[] = {
    "apple", "orange", "grape", "banana",
};

Then you could do something like:

printf("enum apple as a string: %s\n",FRUIT_STRING[apple]);

If the use case is literally just printing the enum name, add the following macros:

#define str(x) #x
#define xstr(x) str(x)

Then do:

printf("enum apple as a string: %s\n", xstr(apple));

In this case, it may seem like the two-level macro is superfluous, however, due to how stringification works in C, it is necessary in some cases. For example, let's say we want to use a #define with an enum:

#define foo apple

int main() {
    printf("%s\n", str(foo));
    printf("%s\n", xstr(foo));
}

The output would be:

foo
apple

This is because str will stringify the input foo rather than expand it to be apple. By using xstr the macro expansion is done first, then that result is stringified.

See Stringification for more information.

Instead of using 404/201 status codes using enum

     public async Task<IActionResult> Login(string email, string password)
    {
        if (string.IsNullOrWhiteSpace(email) || string.IsNullOrWhiteSpace(password))
        { 
            return StatusCode((int)HttpStatusCode.BadRequest, Json("email or password is null")); 
        }

        var user = await _userManager.FindByEmailAsync(email);
        if (user == null)
        {
            return StatusCode((int)HttpStatusCode.BadRequest, Json("Invalid Login and/or password"));

        }
        var passwordSignInResult = await _signInManager.PasswordSignInAsync(user, password, isPersistent: true, lockoutOnFailure: false);
        if (!passwordSignInResult.Succeeded)
        {
            return StatusCode((int)HttpStatusCode.BadRequest, Json("Invalid Login and/or password"));
        }
        return StatusCode((int)HttpStatusCode.OK, Json("Sucess !!!"));
    }

Changing the host to 127.0.0.1 worked for me.

Edit the file in /etc/mysql/my.cnf and add the below mentioned line to the section: client

[client]
port  = 3306
host  = 127.0.0.1
socket  = /var/lib/mysql/mysql.sock

After you are done with it. Execute the following command.

sudo service mysql start

$query = "INSERT INTO myTable VALUES (NULL,'Fname', 'Lname', 'Website')";

Just leaving the value of the AI primary key NULL will assign an auto incremented value.

Try this simple select:

select * 
from artists 
where name like "a%"

Reasons to prefer Service Locator over Inversion of Control (IoC) are:

1. Service Locator is much, much easier for other people to following in your code. IoC is 'magic' but maintenance programmers must understand your convoluted Spring configurations and all the myriad of locations to figure out how you wired your objects.

2. IoC is terrible for debugging configuration problems. In certain classes of applications the application will not start when misconfigured and you may not get a chance to step through what is going on with a debugger.

3. IoC is primarily XML based (Annotations improve things but there is still a lot of XML out there). That means developers can't work on your program unless they know all the magic tags defined by Spring. It is not good enough to know Java anymore. This hinders less experience programmers (ie. it is actually poor design to use a more complicated solution when a simpler solution, such as Service Locator, will fulfill the same requirements). Plus, support for diagnosing XML problems is far weaker than support for Java problems.

4. Dependency injection is more suited to larger programs. Most of the time the additional complexity is not worth it.

5. Often Spring is used in case you "might want to change the implementation later". There are other ways of achieving this without the complexity of Spring IoC.

6. For web applications (Java EE WARs) the Spring context is effectively bound at compile time (unless you want operators to grub around the context in the exploded war). You can make Spring use property files, but with servlets property files will need to be at a pre-determined location, which means you can't deploy multiple servlets of the same time on the same box. You can use Spring with JNDI to change properties at servlet startup time, but if you are using JNDI for administrator-modifiable parameters the need for Spring itself lessens (since JNDI is effectively a Service Locator).

7. With Spring you can lose program Control if Spring is dispatching to your methods. This is convenient and works for many types of applications, but not all. You may need to control program flow when you need to create tasks (threads etc) during initialization or need modifiable resources that Spring didn't know about when the content was bound to your WAR.

Spring is very good for transaction management and has some advantages. It is just that IoC can be over-engineering in many situations and introduce unwarranted complexity for maintainers. Do not automatically use IoC without thinking of ways of not using it first.

First, there is no such thing as a JSON object. JSON is a string format that can be used as a representation of a Javascript object literal.

Since JSON is a string, Javascript will treat it like a string, and not like an object (or array or whatever you are trying to use it as.)

Here is a good JSON reference to clarify this difference:

http://benalman.com/news/2010/03/theres-no-such-thing-as-a-json/

So if you need accomplish the task mentioned in your question, you must convert the JSON string to an object or deal with it as a string, and not as a JSON array. There are several libraries to accomplish this. Look at http://www.json.org/js.html for a reference.

In Skype:

Go to Tools ? Options ? Advanced ? Connections and uncheck the box use port 80 and 443 as alternative. This should help.

As Salman Quader said: In the updated skype(8.x), there is no menu option to change the port. This means this answer is no longer valid.

You're going to have to do something like that i think (convert it into a more concrete type).

Maybe take it into a List of T rather than ArrayList, so that you get type safety and more options for how you implement the comparer.

First, the ++ operator takes precedence over the * operator, and the () operators take precedence over everything else.

Second, the ++number operator is the same as the number++ operator if you're not assigning them to anything. The difference is number++ returns number and then increments number, and ++number increments first and then returns it.

Third, by increasing the value of a pointer, you're incrementing it by the sizeof its contents, that is you're incrementing it as if you were iterating in an array.

So, to sum it all up:

ptr++;    // Pointer moves to the next int position (as if it was an array)
++ptr;    // Pointer moves to the next int position (as if it was an array)
++*ptr;   // The value of ptr is incremented
++(*ptr); // The value of ptr is incremented
++*(ptr); // The value of ptr is incremented
*ptr++;   // Pointer moves to the next int position (as if it was an array). But returns the old content
(*ptr)++; // The value of ptr is incremented
*(ptr)++; // Pointer moves to the next int position (as if it was an array). But returns the old content
*++ptr;   // Pointer moves to the next int position, and then get's accessed, with your code, segfault
*(++ptr); // Pointer moves to the next int position, and then get's accessed, with your code, segfault

As there are a lot of cases in here, I might have made some mistake, please correct me if I'm wrong.

EDIT:

So I was wrong, the precedence is a little more complicated than what I wrote, view it here: http://en.cppreference.com/w/cpp/language/operator_precedence

It is not possible with ALTER statement. If you wish to have the columns in a specific order, you will have to create a newtable, use INSERT INTO newtable (col-x,col-a,col-b) SELECT col-x,col-a,col-b FROM oldtable to transfer the data from the oldtable to the newtable, delete the oldtable and rename the newtable to the oldtable name.

This is not necessarily recommended because it does not matter which order the columns are in the database table. When you use a SELECT statement, you can name the columns and have them returned to you in the order that you desire.

Python installers usually register .py files with the system. If you run the shell explicitly, it works:

import subprocess
subprocess.call(['hello.py', 'htmlfilename.htm'], shell=True)
# --- or ----
subprocess.call('hello.py htmlfilename.htm', shell=True)

You can check your file associations on the command line with

C:\>assoc .py
.py=Python.File

C:\>ftype Python.File
Python.File="C:\Python27\python.exe" "%1" %*

Hello you need to open the index.php from the wamp server and change $suppress_localhost = false; from $suppress_localhost = true; then your wamp will working fine

What is JavaScript garbage collection?

check this

What's important for a web programmer to understand about JavaScript garbage collection, in order to write better code?

In Javascript you don't care about memory allocation and deallocation. The whole problem is demanded to the Javascript interpreter. Leaks are still possible in Javascript, but they are bugs of the interpreter. If you are interested in this topic you could read more in www.memorymanagement.org

To find IP address list I have used this solution

public static IEnumerable<string> GetAddresses()
{
    var host = Dns.GetHostEntry(Dns.GetHostName());
    return (from ip in host.AddressList where ip.AddressFamily == AddressFamily.lo select ip.ToString()).ToList();
}

But I personally like below solution to get local valid IP address

public static IPAddress GetIPAddress(string hostName)
{
    Ping ping = new Ping();
    var replay = ping.Send(hostName);

    if (replay.Status == IPStatus.Success)
    {
        return replay.Address;
    }
    return null;
 }

public static void Main()
{
    Console.WriteLine("Local IP Address: " + GetIPAddress(Dns.GetHostName()));
    Console.WriteLine("Google IP:" + GetIPAddress("google.com");
    Console.ReadLine();
}

The reason you are getting the the IOException is because you are not catching the IOException of your countLines method. You'll want to do something like this:

public static void main(String[] args) {
  int lines = 0;  

  // TODO - Need to get the filename to populate sFileName.  Could
  // come from the command line arguments.

   try {
       lines = LineCounter.countLines(sFileName);
    }
    catch(IOException ex){
        System.out.println (ex.toString());
        System.out.println("Could not find file " + sFileName);
    }

   if(lines > 0) {
     // Do rest of program.
   }
}

I think the project you are looking for is: https://github.com/sarxos/webcam-capture (I'm the author)

There is an example working exactly as you've described - after it's run, the window appear where, after you press "Start" button, you can see live image from webcam device and save it to file after you click on "Snapshot" (source code available, please note that FPS counter in the corner can be disabled):

The project is portable (WinXP, Win7, Win8, Linux, Mac, Raspberry Pi) and does not require any additional software to be installed on the PC.

API is really nice and easy to learn. Example how to capture single image and save it to PNG file:

Webcam webcam = Webcam.getDefault();
webcam.open();
ImageIO.write(webcam.getImage(), "PNG", new File("test.png"));

Here you go:

JS:

$('form').on('submit', function (e) {
    e.preventDefault();

    if (!$('#email').val()) 
        $('#email').parent().append('<span class="error">Please enter your email address.</span>');


    if(!$('#password').val())
         $('#password').parent().append('<span class="error">Please enter your password.</span>');
});

All you have to do is use the GetFocusedRowCellValue method of the gridView control and put it into the RowClick event.

For example:

private void gridView1_RowClick(object sender, DevExpress.XtraGrid.Views.Grid.RowClickEventArgs e)
{
    if (this.gvCodigoNombres.GetFocusedRowCellValue("EMP_dni") == null)
        return;
    MessageBox.Show(""+this.gvCodigoNombres.GetFocusedRowCellValue("EMP_dni").ToString());            
}

Just a mention with jQuery v3.2.1 and Laravel 5.6.

Case 1: The JS object posted directly, like:

$.post("url", {name:'John'}, function( data ) {
});

Corresponding Laravel PHP code should be:

parse_str($request->getContent(),$data); //JSON will be parsed to object $data

Case 2: The JSON string posted, like:

$.post("url", JSON.stringify({name:'John'}), function( data ) {
});

Corresponding Laravel PHP code should be:

$data = json_decode($request->getContent(), true);

Every occurence of "foreach" I've seen (PHP, C#, ...) does basically the same as pythons "for" statement.

These are more or less equivalent:

// PHP:
foreach ($array as $val) {
    print($val);
}

// C#
foreach (String val in array) {
    console.writeline(val);
}

// Python
for val in array:
    print(val)

So, yes, there is a "foreach" in python. It's called "for".

What you're describing is an "array map" function. This could be done with list comprehensions in python:

names = ['tom', 'john', 'simon']

namesCapitalized = [capitalize(n) for n in names]

When you type integer numbers to JtextField1 after key release it will go to inside try , for any other character it will throw NumberFormatException. If you set empty string to jTextField1 inside the catch so the user cannot type any other keys except positive numbers because JTextField1 will be cleared for each bad attempt.

 //Fields 
int x;
JTextField jTextField1;

 //Gui Code Here

private void jTextField1KeyReleased(java.awt.event.KeyEvent evt) {                                        
    try {
        x = Integer.parseInt(jTextField1.getText());
    } catch (NumberFormatException nfe) {
        jTextField1.setText("");
    }

First, repeat this mantra for a little while: "unused memory is wasted memory". The Linux kernel keeps around huge amounts of file metadata and files that were requested, until something that looks more important pushes that data out. It's why you can run:

find /home -type f -name '*.mp3'
find /home -type f -name '*.aac'

and have the second find instance run at ridiculous speed.

Linux only leaves a little bit of memory 'free' to handle spikes in memory usage without too much effort.

Second, you want to find the processes that are eating all your memory; in top use the M command to sort by memory use. Feel free to ignore the VIRT column, that just tells you how much virtual memory has been allocated, not how much memory the process is using. RES reports how much memory is resident, or currently in ram (as opposed to swapped to disk or never actually allocated in the first place, despite being requested).

But, since RES will count e.g. /lib/libc.so.6 memory once for nearly every process, it isn't exactly an awesome measure of how much memory a process is using. The SHR column reports how much memory is shared with other processes, but there is no guarantee that another process is actually sharing -- it could be sharable, just no one else wants to share.

The smem tool is designed to help users better gage just how much memory should really be blamed on each individual process. It does some clever work to figure out what is really unique, what is shared, and proportionally tallies the shared memory to the processes sharing it. smem may help you understand where your memory is going better than top will, but top is an excellent first tool.

in my case, some characters like " , :"'{}[] " maybe corrupt the JSON format, so use try json.loads(str) except to check your input

Try adding "bDestroy": true to the options object literal, e.g.

$('#dataTable').dataTable({
    ...
    ....
    "bDestroy": true
});

Source: iodocs.com

or Remove the first:

$(document).ready(function() {
    $('#example').dataTable();
} );

In your case is the best option vjk.

The behaviour differs depending on whether the target file name already exists or not. It's usually a safety mechanism, and there are at least 3 different cases:

Target file does not exist:

In this case svn mv should work as follows:

$ svn mv old_file_name new_file_name
A         new_file_name
D         old_file_name
$ svn stat
A  +    new_file_name
        > moved from old_file_name
D       old_file_name
        > moved to new_file_name
$ svn commit
Adding     new_file_name
Deleting   old_file_name
Committing transaction...

Target file already exists in repository:

In this case, the target file needs to be removed explicitly, before the source file can be renamed. This can be done in the same transaction as follows:

$ svn mv old_file_name new_file_name 
svn: E155010: Path 'new_file_name' is not a directory
$ svn rm new_file_name 
D         new_file_name
$ svn mv old_file_name new_file_name 
A         new_file_name
D         old_file_name
$ svn stat
R  +    new_file_name
        > moved from old_file_name
D       old_file_name
        > moved to new_file_name
$ svn commit
Replacing      new_file_name
Deleting       old_file_name
Committing transaction...

In the output of svn stat, the R indicates that the file has been replaced, and that the file has a history.

Target file already exists locally (unversioned):

In this case, the content of the local file would be lost. If that's okay, then the file can be removed locally before renaming the existing file.

$ svn mv old_file_name new_file_name 
svn: E155010: Path 'new_file_name' is not a directory
$ rm new_file_name 
$ svn mv old_file_name new_file_name 
A         new_file_name
D         old_file_name
$ svn stat
A  +    new_file_name
        > moved from old_file_name
D       old_file_name
        > moved to new_file_name
$ svn commit
Adding         new_file_name
Deleting       old_file_name
Committing transaction...

Cross Platform, Python 2/3 code:

# import sys, os

def wait_key():
    ''' Wait for a key press on the console and return it. '''
    result = None
    if os.name == 'nt':
        import msvcrt
        result = msvcrt.getch()
    else:
        import termios
        fd = sys.stdin.fileno()

        oldterm = termios.tcgetattr(fd)
        newattr = termios.tcgetattr(fd)
        newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
        termios.tcsetattr(fd, termios.TCSANOW, newattr)

        try:
            result = sys.stdin.read(1)
        except IOError:
            pass
        finally:
            termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)

    return result

I removed the fctl/non-blocking stuff because it was giving IOErrors and I didn't need it. I'm using this code specifically because I want it to block. ;)

Addendum:

I implemented this in a package on PyPI with a lot of other goodies called console:

>>> from console.utils import wait_key

>>> wait_key()
'h'

Simple solution:

<style>
.center {
    margin: auto;

}
</style>

<div class="center">
    <p> somthing goes here </p>
</div>

Try Online

function getShortString($string,$wordCount,$etc = true) 
{
     $expString = explode(' ',$string);
     $wordsInString = count($expString);
     if($wordsInString >= $wordCount )
     {
         $shortText = '';
         for($i=0; $i < $wordCount-1; $i++)
         {
             $shortText .= $expString[$i].' ';
         }
         return  $etc ? $shortText.='...' : $shortText; 
     }
     else return $string;
}

Here's how you can debug CORS requests using curl.

Sending a regular CORS request using cUrl:

curl -H "Origin: http://example.com" --verbose \
  https://www.googleapis.com/discovery/v1/apis?fields=

The -H "Origin: http://example.com" flag is the third party domain making the request. Substitute in whatever your domain is.

The --verbose flag prints out the entire response so you can see the request and response headers.

The url I'm using above is a sample request to a Google API that supports CORS, but you can substitute in whatever url you are testing.

The response should include the Access-Control-Allow-Origin header.

Sending a preflight request using cUrl:

curl -H "Origin: http://example.com" \
  -H "Access-Control-Request-Method: POST" \
  -H "Access-Control-Request-Headers: X-Requested-With" \
  -X OPTIONS --verbose \
  https://www.googleapis.com/discovery/v1/apis?fields=

This looks similar to the regular CORS request with a few additions:

The -H flags send additional preflight request headers to the server

The -X OPTIONS flag indicates that this is an HTTP OPTIONS request.

If the preflight request is successful, the response should include the Access-Control-Allow-Origin, Access-Control-Allow-Methods, and Access-Control-Allow-Headers response headers. If the preflight request was not successful, these headers shouldn't appear, or the HTTP response won't be 200.

You can also specify additional headers, such as User-Agent, by using the -H flag.

Extremely simple method jsfiddle

HTML

<div id="container">
    <div id="element">
        some text
    </div>
</div>

CSS

#container {
    width: 50%; /* desired width */
}

#element {
    height: 0;
    padding-bottom: 100%;
}

A convenient way would be boost's string algorithms library.

#include <boost/algorithm/string/classification.hpp> // Include boost::for is_any_of
#include <boost/algorithm/string/split.hpp> // Include for boost::split
// ...

std::vector<std::string> words;
std::string s;
boost::split(words, s, boost::is_any_of(", "), boost::token_compress_on);

Here's my helper class using Jon Skeet's implementation.

public static class HashCode
{
    public const int Start = 17;

    public static int Hash<T>(this int hash, T obj)
    {
        var h = EqualityComparer<T>.Default.GetHashCode(obj);
        return unchecked((hash * 31) + h);
    }
}

Usage:

public override int GetHashCode()
{
    return HashCode.Start
        .Hash(_field1)
        .Hash(_field2)
        .Hash(_field3);
}

If you want to avoid writing an extension method for System.Int32:

public readonly struct HashCode
{
    private readonly int _value;

    public HashCode(int value) => _value = value;

    public static HashCode Start { get; } = new HashCode(17);

    public static implicit operator int(HashCode hash) => hash._value;

    public HashCode Hash<T>(T obj)
    {
        var h = EqualityComparer<T>.Default.GetHashCode(obj);
        return unchecked(new HashCode((_value * 31) + h));
    }

    public override int GetHashCode() => _value;
}

It still avoids any heap allocation and is used exactly the same way:

public override int GetHashCode()
{
    // This time `HashCode.Start` is not an `Int32`, it's a `HashCode` instance.
    // And the result is implicitly converted to `Int32`.
    return HashCode.Start
        .Hash(_field1)
        .Hash(_field2)     
        .Hash(_field3);
}

Edit (May 2018): EqualityComparer<T>.Default getter is now a JIT intrinsic - the pull request is mentioned by Stephen Toub in this blog post.

Instead of modifying the HTML itself, you should just set the value you want from the relative option element:

$(function() {
    $("#country").val("ID");
});

In this case "ID" is the value of the option "Indonesia"

This will do. Pretty trustworthy. : )

    ""+number;

Just to clarify, this works and acceptable to use unless you are looking for micro optimization.

Factory methods should be considered as an alternative to constructors - mostly when constructors aren't expressive enough, ie.

class Foo{
  public Foo(bool withBar);
}

is not as expressive as:

class Foo{
  public static Foo withBar();
  public static Foo withoutBar();
}

Factory classes are useful when you need a complicated process for constructing the object, when the construction need a dependency that you do not want for the actual class, when you need to construct different objects etc.

To follow debobroto das's answer you can also put after

input.reset();
input.next(); 

I had the same problem and when I tried this. It completely fixed it.

To support SDK version >= 26, you also should build NotificationChanel and set a vibration pattern and sound there. There is a Kotlin code sample:

    val vibrationPattern = longArrayOf(500)
    val soundUri = "<your sound uri>"

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val notificationManager =    
                 getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
            val attr = AudioAttributes.Builder()
                        .setUsage(AudioAttributes.USAGE_ALARM)
                        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                        .build()
            val channelName: CharSequence = Constants.NOTIFICATION_CHANNEL_NAME
            val importance = NotificationManager.IMPORTANCE_HIGH
            val notificationChannel =
                NotificationChannel(Constants.NOTIFICATION_CHANNEL_ID, channelName, importance)
                notificationChannel.enableLights(true)
                notificationChannel.lightColor = Color.RED
                notificationChannel.enableVibration(true)
                notificationChannel.setSound(soundUri, attr)
                notificationChannel.vibrationPattern = vibrationPattern
                notificationManager.createNotificationChannel(notificationChannel)
    }

And this is the builder:

 with(NotificationCompat.Builder(applicationContext, Constants.NOTIFICATION_CHANNEL_ID)) {
        setContentTitle("Some title")
        setContentText("Some content")
        setSmallIcon(R.drawable.ic_logo)
        setAutoCancel(true)    
        setVibrate(vibrationPattern)
        setSound(soundUri)
        setDefaults(Notification.DEFAULT_VIBRATE)
        setContentIntent(
            // this is an extension function of context you should build
            // your own pending intent and place it here
            createNotificationPendingIntent(
                Intent(applicationContext, target).apply {
                    flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
                }
            )
        )

        return build()
    }

Be sure your AudioAttributes are chosen right to read more here.

Excel 2016 I had a similar problem when I created a workbook/file and then I changed the names but somehow the old workbook name was kept. After a lot of googling... well, didn't find any final answer there...

Go to DATA -> Edit Link -> Startup Prompt (at the bottom) Then choose the best option for you.

In my experience, using the 32-bit version is more trouble-free. Unless you are working on applications that make heavy use of memory (mostly scientific computing, that uses more than 2GB memory), you're better off with 32-bit versions because:

1. You generally use less memory.
2. You have less problems using COM (since you are on Windows).
3. If you have to load DLLs, they most probably are also 32-bit. Python 64-bit can't load 32-bit libraries without some heavy hacks running another Python, this time in 32-bit, and using IPC.
4. If you have to load DLLs that you compile yourself, you'll have to compile them to 64-bit, which is usually harder to do (specially if using MinGW on Windows).
5. If you ever use PyInstaller or py2exe, those tools will generate executables with the same bitness of your Python interpreter.

The reason why your code is slow is that your LDAP query retrieves every single user object in your domain even though you're only interested in one user with a common name of "Adit":

dSearcher.Filter = "(&(objectClass=user))";

So to optimize, you need to narrow your LDAP query to just the user you are interested in. Try something like:

dSearcher.Filter = "(&(objectClass=user)(cn=Adit))";

In addition, don't forget to dispose these objects when done:

• DirectoryEntry dEntry
• DirectorySearcher dSearcher

Just remove/comment the following line from your httpd.conf file (etc/httpd/conf)

Require all granted

This is needed till Apache Version 2.2 and is not required from thereon.

The only thing I would add to Mark Peters solution is that you don't need to iterate over the ArrayList - you should be able to use the addAll(Collection) method on the Set. You only need to iterate over the entire list to do the summations.

Get COLUMN INDEX on click:

$(this).closest("td").index();

Get ROW INDEX on click:

$(this).closest("tr").index();

This fixes the math to scale to the max size in both width and height rather than just one depending on the width and height of the original.

- (UIImage *) scaleProportionalToSize: (CGSize)size
{
    float widthRatio = size.width/self.size.width;
    float heightRatio = size.height/self.size.height;

    if(widthRatio > heightRatio)
    {
        size=CGSizeMake(self.size.width*heightRatio,self.size.height*heightRatio);
    } else {
        size=CGSizeMake(self.size.width*widthRatio,self.size.height*widthRatio);
    }

    return [self scaleToSize:size];
}

Don't forget that there is a difference between bash's builtin time (which should be called by default when you do time command) and /usr/bin/time (which should require you to call it by its full path).

The builtin time always prints to stderr, but /usr/bin/time will allow you to send time's output to a specific file, so you do not interfere with the executed command's stderr stream. Also, /usr/bin/time's format is configurable on the command line or by the environment variable TIME, whereas bash's builtin time format is only configured by the TIMEFORMAT environment variable.

I know its quite an old question but I didn't see any answer, which clarify that why and when its possible to break with return.

I would like to explain it with 2 simple examples:

1. Example: In this case, we have a simple iteration and we want to break with return true, if we can find the three.

function canFindThree() {
    for(var i = 0; i < 5; i++) {
        if(i === 3) {
           return true;
        }
    }
}

if we call this function, it will simply return the true.

2. Example In this case, we want to iterate with jquery's each function, which takes anonymous function as parameter.

function canFindThree() {

    var result = false;

    $.each([1, 2, 3, 4, 5], function(key, value) { 
        if(value === 3) {
            result = true;
            return false; //This will only exit the anonymous function and stop the iteration immediatelly.
        }
    });

    return result; //This will exit the function with return true;
}

If you use IIS, Go to the Application pool Select the one that your site uses and click Advance Settings Make sure that the Enable 32-Bit Applications is set to True

You should be able to get a String of length

1. Integer.MAX_VALUE always 2,147,483,647 (2³¹ - 1)
   (Defined by the Java specification, the maximum size of an array, which the String class uses for internal storage)
   OR

2. Half your maximum heap size (since each character is two bytes) whichever is smaller.

With my Android 5 tablet, every time I attempt to use adb, to install a signed release apk, I get the [INSTALL_FAILED_ALREADY_EXISTS] error.

I have to uninstall the debug package first. But, I cannot uninstall using the device's Application Manager!

If do uninstall the debug version with the Application Manager, then I have to re-run the debug build variant from Android Studio, then uninstall it using adb uninstall com.example.mypackagename

Finally, I can use adb install myApp.apk to install the signed release apk.

I'd like to add a "pure pathlib" approach:

from pathlib import Path
from typing import Union

def del_dir(target: Union[Path, str], only_if_empty: bool = False):
    """
    Delete a given directory and its subdirectories.

    :param target: The directory to delete
    :param only_if_empty: Raise RuntimeError if any file is found in the tree
    """
    target = Path(target).expanduser()
    assert target.is_dir()
    for p in sorted(target.glob('**/*'), reverse=True):
        if not p.exists():
            continue
        p.chmod(0o666)
        if p.is_dir():
            p.rmdir()
        else:
            if only_if_empty:
                raise RuntimeError(f'{p.parent} is not empty!')
            p.unlink()
    target.rmdir()

This relies on the fact that Path is orderable, and longer paths will always sort after shorter paths, just like str. Therefore, directories will come before files. If we reverse the sort, files will then come before their respective containers, so we can simply unlink/rmdir them one by one with one pass.

Benefits:

• It's NOT relying on external binaries: everything uses Python's batteries-included modules (Python >= 3.6)
  • Which means that it does not need to repeatedly start a new subprocess to do unlinking
• It's quite fast & simple; you don't have to implement your own recursion
• It's cross-platform (at least, that's what pathlib promises in Python 3.6; no operation above stated to not run on Windows)
• If needed, one can do a very granular logging, e.g., log each deletion as it happens.

Finally, I got the mistake and the reason was I need to stringify the JSON data I was sending. I have to set the content type and datatype in XHR object. So the correct version is here:

$.ajax({
  type: 'POST',
  url: "http://localhost:8080/project/server/rest/subjects",
  data: JSON.stringify({
    "subject:title":"Test Name",
    "subject:description":"Creating test subject to check POST method API",
    "sub:tags": ["facebook:work", "facebook:likes"],
    "sampleSize" : 10,
    "values": ["science", "machine-learning"]
  }),
  error: function(e) {
    console.log(e);
  },
  dataType: "json",
  contentType: "application/json"
});

May be it will help someone else.

a = {2,3,4}
if {1,2} & a:
    pass

Code golf version. Consider using a set if it makes sense to do so. I find this more readable than a list comprehension.

How do I display and redirect output to a file. Suppose if I use dos command, dir > test.txt ,this command will redirect output to file test.txt without displaying the results. how to write a command to display the output and redirect output to a file using DOS i.e., windows command prompt, not in UNIX/LINUX.

You may find these commands in biterscripting ( http://www.biterscripting.com ) useful.

var str output
lf > $output
echo $output                            # Will show output on screen.
echo $output > "test.txt"               # Will write output to file test.txt.
system start "test.txt"                 # Will open file test.txt for viewing/editing.

yes is possible to run your android emulator without have a hardware accelerator. In fact to do that, you need to open your android virtual device. When you reached to system image configure, it suggest you which version of android image you want to use. Whatever version of android system image that you select,you need to make sure that,ABI is armeabi-v7a and, you target is System image ameabi-v7a with google APIs. And then complete the rest of task and check out your emulator.

Given sheet 2:

ColumnA
-------
apple
orange

You can flag the rows in sheet 1 where a value exists in sheet 2:

ColumnA  ColumnB
-------  --------------
pear     =IF(ISERROR(VLOOKUP(A1,Sheet2!A:A,1,FALSE)),"Keep","Delete")
apple    =IF(ISERROR(VLOOKUP(A2,Sheet2!A:A,1,FALSE)),"Keep","Delete")
cherry   =IF(ISERROR(VLOOKUP(A3,Sheet2!A:A,1,FALSE)),"Keep","Delete")
orange   =IF(ISERROR(VLOOKUP(A4,Sheet2!A:A,1,FALSE)),"Keep","Delete")
plum     =IF(ISERROR(VLOOKUP(A5,Sheet2!A:A,1,FALSE)),"Keep","Delete")

The resulting data looks like this:

ColumnA  ColumnB
-------  --------------
pear     Keep
apple    Delete
cherry   Keep
orange   Delete
plum     Keep

You can then easily filter or sort sheet 1 and delete the rows flagged with 'Delete'.

Steps to perform the task:

1. First, download and install the compiler.

2. Then, type the C/C++ program and save it.

3. Then, open the command line and change directory to the particular one where the source file is stored, using cd like so:

   cd C:\Documents and Settings\...
   

4. Then, to compile, type in the command prompt:

   gcc sourcefile_name.c -o outputfile.exe
   

5. Finally, to run the code, type:

   outputfile.exe
   

request.remote_ip is an interpretation of all the available IP address information and it will make a best-guess. If you access the variables directly you assume responsibility for testing them in the correct precedence order. Proxies introduce a number of headers that create environment variables with different names.

Using reduce

This is the simpler and flexible way I found (based on @prunge answer)

Optional<User> user = users.stream()
        .filter(user -> user.getId() == 1)
        .reduce((a, b) -> {
            throw new IllegalStateException("Multiple elements: " + a + ", " + b);
        })

This way you obtain:

• the Optional - as always with your object or Optional.empty() if not present
• the Exception (with eventually YOUR custom type/message) if there's more than one element

Detailed Step by Step instructions I followed to achieve this

• Download bouncycastle JAR from http://repo2.maven.org/maven2/org/bouncycastle/bcprov-ext-jdk15on/1.46/bcprov-ext-jdk15on-1.46.jar or take it from the "doc" folder.
• Configure BouncyCastle for PC using one of the below methods.
  • Adding the BC Provider Statically (Recommended)
    • Copy the bcprov-ext-jdk15on-1.46.jar to each
      • D:\tools\jdk1.5.0_09\jre\lib\ext (JDK (bundled JRE)
      • D:\tools\jre1.5.0_09\lib\ext (JRE)
      • C:\ (location to be used in env variable)
    • Modify the java.security file under
      • D:\tools\jdk1.5.0_09\jre\lib\security
      • D:\tools\jre1.5.0_09\lib\security
      • and add the following entry
        • security.provider.7=org.bouncycastle.jce.provider.BouncyCastleProvider
    • Add the following environment variable in "User Variables" section
      • CLASSPATH=%CLASSPATH%;c:\bcprov-ext-jdk15on-1.46.jar
  • Add bcprov-ext-jdk15on-1.46.jar to CLASSPATH of your project and Add the following line in your code
    • Security.addProvider(new BouncyCastleProvider());
• Generate the Keystore using Bouncy Castle
  • Run the following command
    • keytool -genkey -alias myproject -keystore C:/myproject.keystore -storepass myproject -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider
  • This generates the file C:\myproject.keystore
  • Run the following command to check if it is properly generated or not
    • keytool -list -keystore C:\myproject.keystore -storetype BKS

• Configure BouncyCastle for TOMCAT

  • Open D:\tools\apache-tomcat-6.0.35\conf\server.xml and add the following entry

    • <Connector port="8443" keystorePass="myproject" alias="myproject" keystore="c:/myproject.keystore" keystoreType="BKS" SSLEnabled="true" clientAuth="false" protocol="HTTP/1.1" scheme="https" secure="true" sslProtocol="TLS" sslImplementationName="org.bouncycastle.jce.provider.BouncyCastleProvider"/>

  • Restart the server after these changes.

• Configure BouncyCastle for Android Client
  • No need to configure since Android supports Bouncy Castle Version 1.46 internally in the provided "android.jar".
  • Just implement your version of HTTP Client (MyHttpClient.java can be found below) and set the following in code
    • SSLSocketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
  • If you don't do this, it gives an exception as below
    • javax.net.ssl.SSLException: hostname in certificate didn't match: <192.168.104.66> !=
  • In production mode, change the above code to
    • SSLSocketFactory.setHostnameVerifier(SSLSocketFactory.STRICT_HOSTNAME_VERIFIER);

How to invoke the above code in your Activity class:

DefaultHttpClient client = new MyHttpClient(getApplicationContext());
HttpResponse response = client.execute(...);

You can try

int sum = list.stream().filter(o->o.field>10).mapToInt(o->o.field).sum();

Like explained here

Using this function you can get Image Bitmap. Just pass image url

 public Bitmap getBitmapFromURL(String strURL) {
      try {
        URL url = new URL(strURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
      } catch (IOException e) {
        e.printStackTrace();
        return null;
      }
 }

I did this for a home folder where all the folders are on the desktops of the corresponding users, reachable through a shortcut which did not have the appropriate permissions, so that users couldn't see it even if it was there. So I used Robocopy with the parameter to overwrite the file with the right settings:

FOR /F "tokens=*" %G IN ('dir /b') DO robocopy  "\\server02\Folder with shortcut" "\\server02\home\%G\Desktop" /S /A /V /log+:C:\RobocopyShortcut.txt /XF *.url *.mp3 *.hta *.htm *.mht *.js *.IE5 *.css *.temp *.html *.svg *.ocx *.3gp *.opus *.zzzzz *.avi *.bin *.cab *.mp4 *.mov *.mkv *.flv *.tiff *.tif *.asf *.webm *.exe *.dll *.dl_ *.oc_ *.ex_ *.sy_ *.sys *.msi *.inf *.ini *.bmp *.png *.gif *.jpeg *.jpg *.mpg *.db *.wav *.wma *.wmv *.mpeg *.tmp *.old *.vbs *.log *.bat *.cmd *.zip /SEC /IT /ZB /R:0

As you see there are many file types which I set to ignore (just in case), just set them for your needs or your case scenario.

It was tested on Windows Server 2012, and every switch is documented on Microsoft's sites and others.

From the docs:

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

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

Edit: Further reading led me here:

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

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

This didn't work for me under Safari 10:

<input type="file" accept=".csv" />

I had to write this instead:

<input type="file" accept="text/csv" />

Shadowbox is your best choice. Check it out.

You can do this:

a = a || 0

...which will convert a from any "falsey" value to 0.

The "falsey" values are:

• false
• null
• undefined
• 0
• "" ^{( empty string )}
• NaN ^{( Not a Number )}

Or this if you prefer:

a = a ? a : 0;

...which will have the same effect as above.

If the intent was to test for more than just NaN, then you can do the same, but do a toNumber conversion first.

a = +a || 0

This uses the unary + operator to try to convert a to a number. This has the added benefit of converting things like numeric strings '123' to a number.

The only unexpected thing may be if someone passes an Array that can successfully be converted to a number:

+['123']  // 123

Here we have an Array that has a single member that is a numeric string. It will be successfully converted to a number.

maybe whole database + tables + fields should have the same charset??!

i.e.

CREATE TABLE `politicas` (
  `ID` int(11) NOT NULL AUTO_INCREMENT,
  `Nombre` varchar(250) CHARACTER SET utf8 NOT NULL,
  -------------------------------------^here!!!!!!!!!!!
  PRIMARY KEY (`ID`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
  -------------------------------------------------^here!!!!!!!!!

Use xpath and text()

driver.findElement(By.Xpath("//strong[contains(text(),'" + service +"')]"));

argument for DATEADD function :

DATEADD (*datepart* , *number* , *date* )

datepart can be: yy, qq, mm, dy, dd, wk, dw, hh, mi, ss, ms

number is an expression that can be resolved to an int that is added to a datepart of date

date is an expression that can be resolved to a time, date, smalldatetime, datetime, datetime2, or datetimeoffset value.

I can't comment due to the lack of reputation, but if you are on arch linux, you should be able to find the corresponding libraries on the arch repositories directly. For example for mpl_toolkits.basemap:

pacman -S python-basemap

I experienced the same error when configuring the WP-Mail-SMTP plugin in Wordpress.

The problem would persist even when I have 'triple checked' the settings and login credentials, and am able to log in manually using a browser.

There's a list of steps you can take to fix this.

1. Create a new password for the Gmail account you want to use
2. Enable less secure apps in Google Security settings
3. Use the Display Unlock Captcha page to give your app or website permission to sign in to Gmail. Click Continue or follow the instructions.
4. Sign in using the app or website. The smtp settings that work for me are 1) SMTP Host: smtp.gmail.com 2) SMTP port: 587 3) Encryption: TLS 4) Authentication: SMTP authentication 5) Username: [email protected] 6) Password: examplesecret

I hope my late answer can be of some help.
This will go to rails database console.

rails db

pretty print your query output

.headers on
.mode columns
(turn headers on and show database data in column mode )

Show the tables

.table

'.help' to see help.
Or use SQL statements like 'Select * from cars'

if you are ubuntu user than try this:

sudo apt-get remove jenkins
sudo apt-get remove --auto-remove jenkins

'apt-get remove' command is use to remove package.

I open a text editor, in my case I used Atom. Paste this code

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');

and save as

helloworld.js

in

c:\xampp\htdocs\myproject 

directory. Next I open node.js commamd prompt enter

cd c:\xampp\htdocs\myproject

next

node helloworld.js

next I open my chrome browser and I type

http://localhost:1337

and there it is.

tofile is a convenient function to do this:

import numpy as np
a = np.asarray([ [1,2,3], [4,5,6], [7,8,9] ])
a.tofile('foo.csv',sep=',',format='%10.5f')

The man page has some useful notes:

This is a convenience function for quick storage of array data. Information on endianness and precision is lost, so this method is not a good choice for files intended to archive data or transport data between machines with different endianness. Some of these problems can be overcome by outputting the data as text files, at the expense of speed and file size.

Note. This function does not produce multi-line csv files, it saves everything to one line.

The main method is the entry point of a Java application.

Specifically?when the Java Virtual Machine is told to run an application by specifying its class (by using the java application launcher), it will look for the main method with the signature of public static void main(String[]).

From Sun's java command page:

The java tool launches a Java application. It does this by starting a Java runtime environment, loading a specified class, and invoking that class's main method.

The method must be declared public and static, it must not return any value, and it must accept a String array as a parameter. The method declaration must look like the following:

public static void main(String args[])

For additional resources on how an Java application is executed, please refer to the following sources:

1. Chapter 12: Execution from the Java Language Specification, Third Edition.
2. Chapter 5: Linking, Loading, Initializing from the Java Virtual Machine Specifications, Second Edition.
3. A Closer Look at the "Hello World" Application from the Java Tutorials.

The run method is the entry point for a new Thread or an class implementing the Runnable interface. It is not called by the Java Virutal Machine when it is started up by the java command.

As a Thread or Runnable itself cannot be run directly by the Java Virtual Machine, so it must be invoked by the Thread.start() method. This can be accomplished by instantiating a Thread and calling its start method in the main method of the application:

public class MyRunnable implements Runnable
{
    public void run()
    {
        System.out.println("Hello World!");
    }

    public static void main(String[] args)
    {
        new Thread(new MyRunnable()).start();
    }
}

For more information and an example of how to start a subclass of Thread or a class implementing Runnable, see Defining and Starting a Thread from the Java Tutorials.

The init method is the first method called in an Applet or JApplet.

When an applet is loaded by the Java plugin of a browser or by an applet viewer, it will first call the Applet.init method. Any initializations that are required to use the applet should be executed here. After the init method is complete, the start method is called.

For more information about when the init method of an applet is called, please read about the lifecycle of an applet at The Life Cycle of an Applet from the Java Tutorials.

I'm surprised there are no answers using Regular Expressions. This is pretty much Andrew's answer, using RegExp.test instead of String.indexOf, since it seems to perform better for multiple operations, according to jsPerf tests.
It also seems to be supported on IE6.

function replaceContentInContainer(matchClass, content) {
    var re = new RegExp("(?:^|\\s)" + matchClass + "(?!\\S)"),
        elems = document.getElementsByTagName('*'), i;
    for (i in elems) {
        if (re.test(elems[i].className)) {
            elems[i].innerHTML = content;
        }
    }
}

replaceContentInContainer("box", "This is the replacement text.");

If you look for the same class(es) frequently, you can further improve it by storing the (precompiled) regular expressions elsewhere, and passing them directly to the function, instead of a string.

function replaceContentInContainer(reClass, content) {
    var elems = document.getElementsByTagName('*'), i;
    for (i in elems) {
        if (reClass.test(elems[i].className)) {
            elems[i].innerHTML = content;
        }
    }
}

var reBox = /(?:^|\s)box(?!\S)/;
replaceContentInContainer(reBox, "This is the replacement text.");

You can have a responsive canvas in 3 short and simple steps:

1. Remove the width and height attributes from your <canvas>.

   <canvas id="responsive-canvas"></canvas>
   

2. Using CSS, set the width of your canvas to 100%.

   #responsive-canvas {
     width: 100%;
   }
   

3. Using JavaScript, set the height to some ratio of the width.

   var canvas = document.getElementById('responsive-canvas');
   var heightRatio = 1.5;
   canvas.height = canvas.width * heightRatio;
   

I tried to do this in next way

public static DataTable JoinTwoTables(DataTable innerTable, DataTable outerTable)
        {
            DataTable resultTable = new DataTable();
            var innerTableColumns = new List<string>();
            foreach (DataColumn column in innerTable.Columns)
            {
                innerTableColumns.Add(column.ColumnName);
                resultTable.Columns.Add(column.ColumnName);
            }

            var outerTableColumns = new List<string>();
            foreach (DataColumn column in outerTable.Columns)
            {
                if (!innerTableColumns.Contains(column.ColumnName))
                {
                    outerTableColumns.Add(column.ColumnName);
                    resultTable.Columns.Add(column.ColumnName);
                }                    
            }

            for (int i = 0; i < innerTable.Rows.Count; i++)
            {
                var row = resultTable.NewRow();
                innerTableColumns.ForEach(x =>
                {
                    row[x] = innerTable.Rows[i][x];
                });
                outerTableColumns.ForEach(x => 
                {
                    row[x] = outerTable.Rows[i][x];
                });
                resultTable.Rows.Add(row);
            }
            return resultTable;
        }

HashMap doesnt maintain any order, so if you want any kind of ordering, you need to store that in something else, which is a map and can have some kind of ordering, like LinkedHashMap

below is a simple program, by which you can sort by key, value, ascending ,descending ..( if you modify the compactor, you can use any kind of ordering, on keys and values)

package com.edge.collection.map;

import java.util.Collections;
import java.util.Comparator;
import java.util.HashMap;
import java.util.LinkedHashMap;
import java.util.LinkedList;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;

public class SortMapByKeyValue {
Map<String, Integer> map = new HashMap<String, Integer>();

public static void main(String[] args) {

    SortMapByKeyValue smkv = new SortMapByKeyValue();
    smkv.createMap();

    System.out.println("After sorting by key ascending order......");
    smkv.sortByKey(true);

    System.out.println("After sorting by key descindeng order......");
    smkv.sortByKey(false);

    System.out.println("After sorting by value ascending order......");
    smkv.sortByValue(true);

    System.out.println("After sorting by value  descindeng order......");
    smkv.sortByValue(false);

}

void createMap() {
    map.put("B", 55);
    map.put("A", 80);
    map.put("D", 20);
    map.put("C", 70);
    map.put("AC", 70);
    map.put("BC", 70);
    System.out.println("Before sorting......");
    printMap(map);
}

void sortByValue(boolean order) {

    List<Entry<String, Integer>> list = new LinkedList<Entry<String, Integer>>(map.entrySet());
    Collections.sort(list, new Comparator<Entry<String, Integer>>() {
        public int compare(Entry<String, Integer> o1, Entry<String, Integer> o2) {
            if (order) {
                return o1.getValue().compareTo(o2.getValue());
            } else {
                return o2.getValue().compareTo(o1.getValue());

            }
        }
    });
    Map<String, Integer> sortedMap = new LinkedHashMap<String, Integer>();
    for (Entry<String, Integer> entry : list) {
        sortedMap.put(entry.getKey(), entry.getValue());
    }
    printMap(sortedMap);

}

void sortByKey(boolean order) {

    List<Entry<String, Integer>> list = new LinkedList<Entry<String, Integer>>(map.entrySet());
    Collections.sort(list, new Comparator<Entry<String, Integer>>() {
        public int compare(Entry<String, Integer> o1, Entry<String, Integer> o2) {
            if (order) {
                return o1.getKey().compareTo(o2.getKey());
            } else {
                return o2.getKey().compareTo(o1.getKey());

            }
        }
    });
    Map<String, Integer> sortedMap = new LinkedHashMap<String, Integer>();
    for (Entry<String, Integer> entry : list) {
        sortedMap.put(entry.getKey(), entry.getValue());
    }
    printMap(sortedMap);
}

public void printMap(Map<String, Integer> map) {
    // System.out.println(map);
    for (Entry<String, Integer> entry : map.entrySet()) {
        System.out.println(entry.getKey() + " : " + entry.getValue());
    }
}
}

Your script is blocked from executing due to the execution policy.

You need to run PowerShell as administrator and set it on the client PC to Unrestricted. You can do that by calling Invoke with:

Set-ExecutionPolicy Unrestricted

You can create an array of all the objects inside the dictionary and then use it as a datasource for the TableView.

NSArray *aValuesArray = [yourDict allValues];

I use this simple function for JQuery based project

    var pointerEventToXY = function(e){
      var out = {x:0, y:0};
      if(e.type == 'touchstart' || e.type == 'touchmove' || e.type == 'touchend' || e.type == 'touchcancel'){
        var touch = e.originalEvent.touches[0] || e.originalEvent.changedTouches[0];
        out.x = touch.pageX;
        out.y = touch.pageY;
      } else if (e.type == 'mousedown' || e.type == 'mouseup' || e.type == 'mousemove' || e.type == 'mouseover'|| e.type=='mouseout' || e.type=='mouseenter' || e.type=='mouseleave') {
        out.x = e.pageX;
        out.y = e.pageY;
      }
      return out;
    };

example:

$('a').on('mousedown touchstart', function(e){
  console.log(pointerEventToXY(e)); // will return obj ..kind of {x:20,y:40}
})

hope this will be usefull for you ;)

In conclusion, when you use a local variable of a type that implements IDisposable, always, without exception, use using¹.

If you use nonlocal IDisposable variables, then always implement the IDisposable pattern.

Two simple rules, no exception¹. Preventing resource leaks otherwise is a real pain in the *ss.

¹⁾: The only exception is – when you're handling exceptions. It might then be less code to call Dispose explicitly in the finally block.

If you are so serious about doing it with services using mediaplayer

Intent svc=new Intent(this, BackgroundSoundService.class);
startService(svc);

public class BackgroundSoundService extends Service {
    private static final String TAG = null;
    MediaPlayer player;
    public IBinder onBind(Intent arg0) {

        return null;
    }
    @Override
    public void onCreate() {
        super.onCreate();
        player = MediaPlayer.create(this, R.raw.idil);
        player.setLooping(true); // Set looping
        player.setVolume(100,100);

    }
    public int onStartCommand(Intent intent, int flags, int startId) {
        player.start();
        return 1;
    }

    public void onStart(Intent intent, int startId) {
        // TO DO
    }
    public IBinder onUnBind(Intent arg0) {
        // TO DO Auto-generated method
        return null;
    }

    public void onStop() {

    }
    public void onPause() {

    }
    @Override
    public void onDestroy() {
        player.stop();
        player.release();
    }

    @Override
    public void onLowMemory() {

    }
}

Please call this service in Manifest Make sure there is no space at the end of the .BackgroundSoundService string

<service android:enabled="true" android:name=".BackgroundSoundService" />

How it should be done in the tidyverse:

df.dplyr.purrr <- listOfDataFrames %>% map_df(bind_rows)

The loopj library can be used straight-forward for this purpose:

SyncHttpClient client = new SyncHttpClient();
RequestParams params = new RequestParams();
params.put("text", "some string");
params.put("image", new File(imagePath));

client.post("http://example.com", params, new TextHttpResponseHandler() {
  @Override
  public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
    // error handling
  }

  @Override
  public void onSuccess(int statusCode, Header[] headers, String responseString) {
    // success
  }
});

Arrays have numerical indexes. So,

a = new Array();
a['a1']='foo';
a['a2']='bar';

and

b = new Array(2);
b['b1']='foo';
b['b2']='bar';

are not adding elements to the array, but adding .a1 and .a2 properties to the a object (arrays are objects too). As further evidence, if you did this:

a = new Array();
a['a1']='foo';
a['a2']='bar';
console.log(a.length);   // outputs zero because there are no items in the array

Your third option:

c=['c1','c2','c3'];

is assigning the variable c an array with three elements. Those three elements can be accessed as: c[0], c[1] and c[2]. In other words, c[0] === 'c1' and c.length === 3.

Javascript does not use its array functionality for what other languages call associative arrays where you can use any type of key in the array. You can implement most of the functionality of an associative array by just using an object in javascript where each item is just a property like this.

a = {};
a['a1']='foo';
a['a2']='bar';

It is generally a mistake to use an array for this purpose as it just confuses people reading your code and leads to false assumptions about how the code works.

Either return; from the method early, or throw an exception.

There is no other way to prevent further code from being executed short of exiting the process completely.

If you are looking for a generic way of doing this via MySQL, you could simply use a SELECT statement, and add the WHERE clause to it.

This will grab all fields for all rows, where the date stored in field "date" is before "now".

SELECT * FROM table WHERE UNIX_TIMESTAMP(`date`) < UNIX_TIMESTAMP()

Personally, I found this method to be more gentle on newbies in MySQL, since it uses the standard SELECT statement with WHERE to fetch the results. Obviously, you could grab only the fields relevant if you wanted to, by listing them instead of using a wildcard (*).

For creating arrays of class Objects you can use the java.util.ArrayList. to define an array:

public ArrayList<ClassName> arrayName;
arrayName = new ArrayList<ClassName>();

Assign values to the array:

arrayName.add(new ClassName(class parameters go here);

Read from the array:

ClassName variableName = arrayName.get(index);

Note:

variableName is a reference to the array meaning that manipulating variableName will manipulate arrayName

for loops:

//repeats for every value in the array
for (ClassName variableName : arrayName){
}
//Note that using this for loop prevents you from editing arrayName

for loop that allows you to edit arrayName (conventional for loop):

for (int i = 0; i < arrayName.size(); i++){
    //manipulate array here
}

You need to wrap your method call into another one, where you do not throw checked exceptions. You can still throw anything that is a subclass of RuntimeException.

A normal wrapping idiom is something like:

private void safeFoo(final A a) {
    try {
        a.foo();
    } catch (Exception ex) {
        throw new RuntimeException(ex);
    }
}

(Supertype exception Exception is only used as example, never try to catch it yourself)

Then you can call it with: as.forEach(this::safeFoo).

There is one more Java mapping engine/framework Nomin: http://nomin.sourceforge.net.

There are couple of way which can be used.

const stations = [
  {call:'station one',frequency:'000'},
  {call:'station two',frequency:'001'}
];
const callList = stations.map(({call}) => call)

Solution 1

<p>{callList.join(', ')}</p>

Solution 2

<ol>    
  { callList && callList.map(item => <li>{item}</li>) }
</ol>

Of course there are other ways also available.

I've forgot to add the PostgreSQL JDBC Driver into my project (Mvnrepository).

Gradle:

// http://mvnrepository.com/artifact/postgresql/postgresql
compile group: 'postgresql', name: 'postgresql', version: '9.0-801.jdbc4'

Maven:

<dependency>
    <groupId>postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>9.0-801.jdbc4</version>
</dependency>

You can also download the JAR and import to your project manually.

Below is the code I used to replace some text, with colored text. It's simple, took the text and replace it within an HTML tag. It works for each words in that class tags.

$('.hightlight').each(function(){
    //highlight_words('going', this);
    var high = 'going';
    high = high.replace(/\W/g, '');
    var str = high.split(" ");
    var text = $(this).text();
    text = text.replace(str, "<span style='color: blue'>"+str+"</span>");
    $(this).html(text);
});

private fields, public fields, constructors, properties, public methods, private methods

As StyleCop is part of the MS build process you could view that as a de facto standard

For this is important to understand the difference between Merge and Rebase.

Rebases are how changes should pass from the top of hierarchy downwards and merges are how they flow back upwards.

Because it's the size of an instance of the type - presumably enum values are stored as (32-bit / 4-byte) ints here.

check your $PATH

tox has a command line mode:

audrey:tests jluc$ pip list | grep tox
tox (2.3.1)

where is it?

(edit: the 2.7 stuff doesn't matter much here, sub in any 3.x and pip's behaving pretty much the same way)

audrey:tests jluc$ which tox
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/tox

and what's in my $PATH?

audrey:tests jluc$ echo $PATH
/opt/chefdk/bin:/opt/chefdk/embedded/bin:/opt/local/bin:..../opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin...

Notice the /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin? That's what allows finding my pip-installed stuff

Now, to see where things are from Python, try doing this (substitute rosdep for tox).

$python
>>> import tox
>>> tox.__file__

that prints out:

'/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/tox/__init__.pyc'

Now, cd to the directory right above lib in the above. Do you see a bin directory? Do you see rosdep in that bin? If so try adding the bin to your $PATH.

audrey:2.7 jluc$ cd /opt/local/Library/Frameworks/Python.framework/Versions/2.7
audrey:2.7 jluc$ ls -1

output:

• Divide and Conquer
  • They broke into non-overlapping sub-problems
  • Example: factorial numbers i.e. fact(n) = n*fact(n-1)

fact(5) = 5* fact(4) = 5 * (4 * fact(3))= 5 * 4 * (3 *fact(2))= 5 * 4 * 3 * 2 * (fact(1))

As we can see above, no fact(x) is repeated so factorial has non overlapping problems.

• Dynamic Programming
  • They Broke into overlapping sub-problems
  • Example: Fibonacci numbers i.e. fib(n) = fib(n-1) + fib(n-2)

fib(5) = fib(4) + fib(3) = (fib(3)+fib(2)) + (fib(2)+fib(1))

As we can see above, fib(4) and fib(3) both use fib(2). similarly so many fib(x) gets repeated. that's why Fibonacci has overlapping sub-problems.

• As a result of the repetition of sub-problem in DP, we can keep such results in a table and save computation effort. this is called as memoization

As I understand it, roles were initially defined by XHTML but were deprecated. However, they are now defined by HTML 5, see here: https://www.w3.org/WAI/PF/aria/roles#abstract_roles_header

The purpose of the role attribute is to identify to parsing software the exact function of an element (and its children) as part of a web application. This is mostly as an accessibility thing for screen readers, but I can also see it as being useful for embedded browsers and screen scrapers. In order to be useful to the unusual HTML client, the attribute needs to be set to one of the roles from the spec I linked. If you make up your own, this 'future' functionality can't work - a comment would be better.

Practicalities here: http://www.accessibleculture.org/articles/2011/04/html5-aria-2011/

How about:

SimpleDateFormat fmt = new SimpleDateFormat("yyyyMMdd");
return fmt.format(date1).equals(fmt.format(date2));

You can also set the timezone to the SimpleDateFormat, if needed.

As an addendum, if you want to reapply your changes on top of the remote, you can also try:

git pull --rebase origin master

If you then want to undo some of your changes (but perhaps not all of them) you can use:

git reset SHA_HASH

Then do some adjustment and recommit.

This is often caused by an attempt to process a null object. An example, trying to empty a Bindable list that is null will trigger the exception:

public class MyViewModel {
    [BindableProperty]
    public virtual IList<Products> ProductsList{ get; set; }

    public MyViewModel ()
    {
        ProductsList.Clear(); // here is the problem
    }
}

This could easily be fixed by checking for null:

if (ProductsList!= null) ProductsList.Clear();

The old way:

xcopy [source] [destination] /E

xcopy is deprecated. Robocopy replaces Xcopy. It comes with Windows 8, 8.1 and 10.

robocopy [source] [destination] /E

robocopy has several advantages:

• copy paths exceeding 259 characters
• multithreaded copying

Timeit has two big flaws: it doesn't return the return value of the function, and it uses eval, which requires passing in extra setup code for imports. This solves both problems simply and elegantly:

def timed(f):
  start = time.time()
  ret = f()
  elapsed = time.time() - start
  return ret, elapsed

timed(lambda: database.foo.execute('select count(*) from source.apachelog'))
(<sqlalchemy.engine.result.ResultProxy object at 0x7fd6c20fc690>, 4.07547402381897)

myFile = open('today','r')

ips = {}

for line in myFile:
    parts = line.split()
    if parts[1] == 'Failure':
        ips.setdefault(parts[0], 0)
        ips[parts[0]] += 1

of = open('failed.py', 'w')
for ip in [k for k, v in ips.iteritems() if v >=5]:
    of.write(k+'\n')

Check out setdefault, it makes the code a little more legible. Then you dump your data with the file object's write method.

In my case it was because i was connecting to HTTP and it was running on HTTPS

You can use isset function:

if(isset($_GET['id'])) {
    // id index exists
}

You can create a handy function to return default value if index doesn't exist:

function Get($index, $defaultValue) {
    return isset($_GET[$index]) ? $_GET[$index] : $defaultValue;
}

// prints "invalid id" if $_GET['id'] is not set
echo Get('id', 'invalid id');

You can also try to validate it at the same time:

function GetInt($index, $defaultValue) {
    return isset($_GET[$index]) && ctype_digit($_GET[$index])
            ? (int)$_GET[$index] 
            : $defaultValue;
}

// prints 0 if $_GET['id'] is not set or is not numeric
echo GetInt('id', 0);

Include "B.h" in "A.h". That brings in the declaration of 'B' for the compiler while compiling 'A'.

The first bullet holds in the case of OP.

$3.4.1/7 -

"A name used in the definition of a class X outside of a member function body or nested class definition27) shall be declared in one of the following ways:

— before its use in class X or be a member of a base class of X (10.2), or

— if X is a nested class of class Y (9.7), before the definition of X in Y, or shall be a member of a base class of Y (this lookup applies in turn to Y’s enclosing classes, starting with the innermost enclosing class),28) or

— if X is a local class (9.8) or is a nested class of a local class, before the definition of class X in a block enclosing the definition of class X, or

— if X is a member of namespace N, or is a nested class of a class that is a member of N, or is a local class or a nested class within a local class of a function that is a member of N, before the definition of class X in namespace N or in one of N’s enclosing namespaces."

You could just create a new database and then go to tasks, import data, and import all the data from the database you want to duplicate to the database you just created.

My solution is based on @marc_s solution, i just concatenated columns in cases that a constraint is based on more than one column:

SELECT
   FK.[name] AS ForeignKeyConstraintName
  ,SCHEMA_NAME(FT.schema_id) + '.' + FT.[name] AS ForeignTable
  ,STUFF(ForeignColumns.ForeignColumns, 1, 2, '') AS ForeignColumns
  ,SCHEMA_NAME(RT.schema_id) + '.' + RT.[name] AS ReferencedTable
  ,STUFF(ReferencedColumns.ReferencedColumns, 1, 2, '') AS ReferencedColumns

You can create an alias in .bashrc file as follows

alias vg='valgrind --leak-check=full -v --track-origins=yes --log-file=vg_logfile.out'

So whenever you want to check memory leaks, just do simply

vg ./<name of your executable> <command line parameters to your executable>

This will generate a Valgrind log file in the current directory.

I didn't want to install a package just for that purpose so I ended up using this in my init.coffee:

spawn = require('child_process').spawn
atom.commands.add 'atom-text-editor', 'open-terminal', ->
  file = atom.workspace.getActiveTextEditor().getPath()
  dir = atom.project.getDirectoryForProjectPath(file).path
  spawn 'mate-terminal', ["--working-directory=#{dir}"], {
    detached: true
  }

With that, I could map ctrl-shift-t to the open-terminal command and it opens a mate-terminal.

in case anyone using codeigniter 3 bootstrap with datatable.

below is my fix in config/ci_boostrap.php

//'assets/dist/frontend/lib.min.js',
//lib.min.js has conflict with datatables.js and i removed it replace with jquery.js
'assets/dist/frontend/jquery-3.3.1.min.js',
'assets/dist/frontend/app.min.js',
'assets/dist/datatables.js'

I feel this is easier to understand

[row[i] for row in a for i in range(len(a))]

result: [1, 2, 3, 4]
