Scene items consistently work in virtualized conditions when they are designed with the appropriate basic working framework and equipment. Scene is utilized to investigate information with boundless visual examination.

How does Tableau function?

The significant work of Tableau programming is to associate and concentrate the information put away in different spots. It can pull information from any stage. Scene can extricate information from any data set, be it Excel, PDF, Oracle, or even Amazon Web Services.

Whenever Tableau is dispatched, prepared information connectors are accessible which permit you to associate with any data set.

The information extricated can be associated live to the Tableau information motor, Tableau Desktop. This is the place where a Data Analyst or a Data Engineer work with the information that was pulled up and create perception. The made dashboards are imparted to clients as static documents. The clients getting dashboards see the records utilizing Tableau Reader.

The information separated from Tableau Desktop can be distributed to Tableau Server, which is an undertaking stage where joint effort, conveyance, administration, security model, and computerization highlights are upheld. Utilizing Tableau Server, end clients can get to the records from all areas, be it a work area or a cell phone. Need to become ace in Tableau look at this Tableau Training in Sydney.

Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community

Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes

Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.

Mailboxer: A Rails Gem to Send Messages inside A Web Application

Mailboxer

This project is based on the need for a private message system for ging / social_stream. Instead of creating our core message system heavily dependent on our development, we are trying to implement a generic and potent messaging gem.

After looking for a good gem to use we noticed the lack of messaging gems and functionality in them. Mailboxer tries to fill this void delivering a powerful and flexible message system. It supports the use of conversations with two or more participants, sending notifications to recipients (intended to be used as system notifications “Your picture has new comments”, “John Doe has updated his document”, etc.), and emailing the messageable model (if configured to do so). It has a complete implementation of a Mailbox object for each messageable with inbox, sentbox and trash.

The gem is constantly growing and improving its functionality. As it is used with our parallel development ging / social_stream we are finding and fixing bugs continously. If you want some functionality not supported yet or marked as TODO, you can create an issue to ask for it. It will be great feedback for us, and we will know what you may find useful in the gem.

Mailboxer was born from the great, but outdated, code from lpsergi / acts_as_messageable.

We are now working to make exhaustive documentation and some wiki pages in order to make it even easier to use the gem to its full potential. Please, give us some time if you find something missing or ask for it. You can also find us on the Gitter room for this repo. Join us there to talk.

Installation

Add to your Gemfile:

gem 'mailboxer'

Then run:

$ bundle install

Run install script:

$ rails g mailboxer:install

And don't forget to migrate your database:

$ rake db:migrate

You can also generate email views:

$ rails g mailboxer:views

Upgrading

If upgrading from 0.11.0 to 0.12.0, run the following generators:

$ rails generate mailboxer:namespacing_compatibility
$ rails generate mailboxer:install -s

Then, migrate your database:

$ rake db:migrate

Requirements & Settings

Emails

We are now adding support for sending emails when a Notification or a Message is sent to one or more recipients. You should modify the mailboxer initializer (/config/initializer/mailboxer.rb) to edit these settings:

Mailboxer.setup do |config|
  #Enables or disables email sending for Notifications and Messages
  config.uses_emails = true
  #Configures the default `from` address for the email sent for Messages and Notifications of Mailboxer
  config.default_from = "no-reply@dit.upm.es"
  ...
end

You can change the way in which emails are delivered by specifying a custom implementation of notification and message mailers:

Mailboxer.setup do |config|
  config.notification_mailer = CustomNotificationMailer
  config.message_mailer = CustomMessageMailer
  ...
end

If you have subclassed the Mailboxer::Notification class, you can specify the mailers using a member method:

class NewDocumentNotification < Mailboxer::Notification
  def mailer_class
    NewDocumentNotificationMailer
  end
end

class NewCommentNotification < Mailboxer::Notification
  def mailer_class
    NewDocumentNotificationMailer
  end
end

Otherwise, the mailer class will be determined by appending 'Mailer' to the mailable class name.

User identities

Users must have an identity defined by a name and an email. We must ensure that Messageable models have some specific methods. These methods are:

#Returning any kind of identification you want for the model
def name
  return "You should add method :name in your Messageable model"
end
#Returning the email address of the model if an email should be sent for this object (Message or Notification).
#If no mail has to be sent, return nil.
def mailboxer_email(object)
  #Check if an email should be sent for that object
  #if true
  return "define_email@on_your.model"
  #if false
  #return nil
end

These names are explicit enough to avoid colliding with other methods, but as long as you need to change them you can do it by using mailboxer initializer (/config/initializer/mailboxer.rb). Just add or uncomment the following lines:

Mailboxer.setup do |config|
  # ...
  #Configures the methods needed by mailboxer
  config.email_method = :mailboxer_email
  config.name_method = :name
  config.notify_method = :notify
  # ...
end

You may change whatever you want or need. For example:

config.email_method = :notification_email
config.name_method = :display_name
config.notify_method = :notify_mailboxer

Will use the method notification_email(object) instead of mailboxer_email(object), display_name for name and notify_mailboxer for notify.

Using default or custom method names, if your model doesn't implement them, Mailboxer will use dummy methods so as to notify you of missing methods rather than crashing.

Preparing your models

In your model:

class User < ActiveRecord::Base
  acts_as_messageable
end

You are not limited to the User model. You can use Mailboxer in any other model and use it in several different models. If you have ducks and cylons in your application and you want to exchange messages as if they were the same, just add acts_as_messageable to each one and you will be able to send duck-duck, duck-cylon, cylon-duck and cylon-cylon messages. Of course, you can extend it for as many classes as you need.

Example:

class Duck < ActiveRecord::Base
  acts_as_messageable
end
class Cylon < ActiveRecord::Base
  acts_as_messageable
end

Mailboxer API

Warning for version 0.8.0

Version 0.8.0 sees Messageable#read and Messageable#unread renamed to mark_as_(un)read, and Receipt#read and Receipt#unread to is_(un)read. This may break existing applications, but read is a reserved name for Active Record, and the best pratice in this case is simply avoid using it.

How can I send a message?

#alfa wants to send a message to beta
alfa.send_message(beta, "Body", "subject")

How can I read the messages of a conversation?

As a messageable, what you receive are receipts, which are associated with the message itself. You should retrieve your receipts for the conversation and get the message associated with them.

This is done this way because receipts save the information about the relation between messageable and the messages: is it read?, is it trashed?, etc.

#alfa gets the last conversation (chronologically, the first in the inbox)
conversation = alfa.mailbox.inbox.first

#alfa gets it receipts chronologically ordered.
receipts = conversation.receipts_for alfa

#using the receipts (i.e. in the view)
receipts.each do |receipt|
  ...
  message = receipt.message
  read = receipt.is_unread? #or message.is_unread?(alfa)
  ...
end

How can I reply to a message?

#alfa wants to reply to all in a conversation
#using a receipt
alfa.reply_to_all(receipt, "Reply body")

#using a conversation
alfa.reply_to_conversation(conversation, "Reply body")
#alfa wants to reply to the sender of a message (and ONLY the sender)
#using a receipt
alfa.reply_to_sender(receipt, "Reply body")

How can I delete a message from trash?

#delete conversations forever for one receipt (still in database)
receipt.mark_as_deleted

#you can mark conversation as deleted for one participant
conversation.mark_as_deleted participant

#Mark the object as deleted for messageable
#Object can be:
  #* A Receipt
  #* A Conversation
  #* A Notification
  #* A Message
  #* An array with any of them
alfa.mark_as_deleted conversation

# get available message for specific user
conversation.messages_for(alfa)

How can I retrieve my conversations?

#alfa wants to retrieve all his conversations
alfa.mailbox.conversations

#A wants to retrieve his inbox
alfa.mailbox.inbox

#A wants to retrieve his sent conversations
alfa.mailbox.sentbox

#alfa wants to retrieve his trashed conversations
alfa.mailbox.trash

How can I paginate conversations?

You can use Kaminari to paginate the conversations as normal. Please, make sure you use the last version as mailboxer uses select('DISTINCT conversations.*') which was not respected before Kaminari 0.12.4 according to its changelog. Working correctly on Kaminari 0.13.0.

#Paginating all conversations using :page parameter and 9 per page
conversations = alfa.mailbox.conversations.page(params[:page]).per(9)

#Paginating received conversations using :page parameter and 9 per page
conversations = alfa.mailbox.inbox.page(params[:page]).per(9)

#Paginating sent conversations using :page parameter and 9 per page
conversations = alfa.mailbox.sentbox.page(params[:page]).per(9)

#Paginating trashed conversations using :page parameter and 9 per page
conversations = alfa.mailbox.trash.page(params[:page]).per(9)

You can take a look at the full documentation for Mailboxer in rubydoc.info.

Do you want to test Mailboxer?

Thanks to Roman Kushnir (@RKushnir) you can test Mailboxer with this sample app.

I need a GUI!

How to use Tailwind CSS with a React App

What is Tailwind CSS?

Tailwind is a modern CSS framework. It is a utility-first-based framework and provides you with a unique set of utility classes which makes the development process very easy and results in making a unique design. Utility-first CSS is fast, robust, and very efficient making your coding hassle-free. Tailwind CSS is also not opinionated; it means you are totally free to customize the design lament and website's component.

Tailwind is a power pack of everything you need to create a website without writing any custom CSS. The main difference between Tailwind and its competitors is that it gives developers complete control over the styling of a web application.

Why Use Tailwind CSS?

There’s a lot that goes on in web development. It can sometimes, thus, become an overly complicated task. Mapping the impact of styling might become tedious and time-consuming hampering the progress of the application/website.

Implementing Tailwind CSS will eliminate all the above-mentioned issues. Tailwind CSS creates small utilities with a defined set of options enabling easy integration of existing classes directly into the HTML code. Custom styling can be provided to the components with the help of this framework.

Tailwind CSS: Pros and Cons

Tailwind CSS: Advantages

  1. Control Over Styling
  2. Faster CSS Styling Process
  3. Responsiveness and Security
  4. Additional Features

Tailwind CSS: Disadvantages

  1. Styling and HTML are Mixed
  2. It Takes Time to Learn
  3. Lack of Important Components
  4. Documentation

In this blog, we’ll demonstrate how to make Tailwind CSS work inside your React project without having to eject Create React App.

Using Tailwind CSS in your React App

First, open your terminal and type the following commands to create a new project.

#using NPX
npx create-react-app tailwindreact-app

#using NPM
npm init react-app tailwindreact-app

#using yarn 
yarn create react-app tailwindreact-app

create-react-app is the official React build tool for scaffolding new React projects. It leverages webpack and babel and reduces the hassle of configuring and setting up the build processes for projects, allowing you to focus on writing the code that powers your app.

Next, install Tailwind and its dependencies:

cd tailwindreact-app

npm install tailwindcss postcss-cli autoprefixer -D

We need to initialize Tailwind CSS by creating the default configurations. Type the command below in your terminal:

npx tailwind init tailwind.config.js --full

This command creates a tailwind.js in your project’s base directory; the file contains the configuration, such as our colors, themes, media queries, and so on. It’s a useful file that helps with predefined sets of properties which will aid the need to re-brand certain conventions or properties if the need arises.

Now update tailwind.config.js:

module.exports = {
  content: ["./src/**/*.{js,jsx,ts,tsx}"],
}

Checkout This Tool: Open Port Check Tool

How To Configure PostCSS?

The PostCSS documentation states that:

“PostCSS is a tool for transforming styles with JS plugins. These plugins can lint your CSS, support variables and mixins, transpile future CSS syntax, inline images, and more.”

Why Autoprefixer?

It’s necessary to install Autoprefixer alongside Tailwind CSS because Autoprefixer usually tracks caniuse.com to see which CSS properties need to be prefixed. Hence, Tailwind CSS does not provide any vendor prefixes. If you’re curious as a cat in regards to PostCSS navigates to their documentation.

Create a PostCSS configuration file in your base directory manually or using the command:

touch postcss.config.js

Add the following lines of code to your PostCSS file:

const tailwindcss = require('tailwindcss');
module.exports = {
    plugins: [
        tailwindcss('./tailwind.config.js'),
        require('autoprefixer')
    ],
};

Because PostCSS is necessary to lint our CSS, hence this configuration.
