Ruby on Rails Development Benefits and Pitfalls
Understanding how the many components of digital design and development are connected is crucial for web developers. Each pillar supports the span, much like a bridge, and if any one of them fails, the entire structure falls. Both poor design and poorly written code can obliterate even the most complex design solutions. Every component contributes to the final result, a user-friendly product.
We have provided you with some background information on the terms, procedures, and tools used in web development in previous posts. This article will carry on that theme. We're going to discuss one of the widely used web development tools, Ruby on Rails, and share some of its advantages and disadvantages with you.
brief history
A brief history will be presented first. Ruby is an open source, dynamic, object-oriented programming language with an emphasis on efficiency and productivity. The original version of the language, Ruby, which was created by Yukihiro "Matz" Matsumoto, was initially made available in the 1990s. Today, it provides power to popular services like Basecamp, Hulu, the original Twitter, and Living Social. Because Ruby offers a framework that supports a high level of developer flexibility, many businesses, including BBW, Cisco, CNET, IBM, JP Morgan, NASA, and Yahoo, employ it in some capacity.
The open-source Ruby on Rails web application framework is designed to increase programmers' long-term productivity. From his work on the project management tool Basecamp at the web application firm also known as Basecamp, David Heinemeier Hansson extracted Ruby on Rails. In July 2004, Hansson first made Rails available as open source. Even well-known companies like Amazon and eBay have Rails projects.
From my work on Basecamp, a project collaboration tool from 37signals, Rails (Ruby on Rails) was extracted. It was therefore driven by needs rather than predictions. And I think a large reason why we're doing so well right now is because of it. I didn't make an effort to consider what certain programmers could require for a dream job. I merely constructed what I required to complete my work cheerfully. David Heinemeier Hansson, the author of Ruby on Rails, is a different interviewee.
What is Ruby on Rails?
Model-view-controller (MVC) is how Rails apps work. This technique is utilized by numerous other web frameworks, including AngularJS (JavaScript), Django (Python), and CakePHP (PHP).Models, Views, and Controllers are the three components that make up the apps, according to this. These parts perform the following functions:
They include the functionality needed to modify and get the many types of data the app uses. A model is represented as a class in Rails. They are not low-level data types like strings or arrays.
Create the logic that connects views and models (and the data they are linked with). They perform input processing, make method calls, and send data to

Ruby on Rails, often simply referred to as Rails, is an open-source web application framework written in Ruby. It follows the Model-View-Controller (MVC) architectural pattern, which separates an application into three interconnected components to promote code Ruby Rails Web Development organization and maintainability. Ruby on Rails has gained popularity for its focus on developer productivity and its convention-over-configuration philosophy, which significantly reduces the need for boilerplate code and configuration.

How does Ruby on Rails relate to the Ruby programming language? What is Ruby on Rails?
Without initially discussing Ruby, there is no purpose in discussing Ruby on Rails. Ruby is a general-purpose, object-oriented programming language that was first introduced in 1995. It has specific advantages for online programming. The SEO Expate Bangladesh Ltd Ruby programming language is expanded by the software package library known as Rails, which was created at MIT under permission. To simplify the process of creating online apps, platforms, and web services, RoR essentially offers libraries of pre-made components and default structures that can be assembled, expanded, and updated. If Ruby were English, Ruby on Rails would be a collection of sample sentences, clauses, and paragraphs for producing business plans, proposals, reports, contracts, resumes, and other documents. We save time by using templates, and the outcomes are excellent. The Rails program is installed on.
Ruby on Rails: Is it dead?
The answer is unquestionably "No, Ruby on Rails is neither dead nor dying in 2023." Millions of people interact everyday with RoR-based apps, platforms, and websites, with relatively few annoyances or bugs, from Github and AirBnB to Soundcloud, Shopify, and Fiverr. You may be confident that a Ruby on Rails expert is around whenever an active RoR app is present. Even while it

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. INTRODUCTION
Ruby on Rails, sometimes known as "RoR" or just Rails, is an open source
framework for Web development in Ruby, an object-oriented programming
(OOP) language similar to Perl and Python.
The principle difference between Ruby on Rails and other frameworks for
development lies in the speed and ease of use that developers working within
the environment enjoy.
Changes made to applications are immediately applied, avoiding the time
consuming steps normally associated with the web development cycle.
4. NOW, WHAT’S A WEB AppLICATION ??
A web application is an application that is accessed via web browser over
a network such as the Internet or an intranet. The web Application consists
of a browser, an application and a database.
The browser makes a request to the web application, which then interacts
with the database, and produce suitable output and sends it back to the
browser.
5. WHAT’S RUBY ?
Ruby is a dynamic, reflective, general purpose object-oriented
programming language that combines syntax inspired by Perl with
Smalltalk-like features.
Ruby originated in Japan during the mid-1990s and was initially
developed and designed by Yukihiro "Matz" Matsumoto. It is based on
Perl, Smalltalk, Eiffel, Ada, and Lisp.
Ruby supports multiple programming paradigms, including
functional, object oriented, imperative and reflective. It is similar in
varying respects to Python, Perl, Lisp, Dylan, and CLU.
6. FEATURES OF RUBY !!
Objects everywhere! - In Ruby everything is an object including simple
numeric values. Here is an example,
Blocks - Blocks is a powerful feature in Ruby which simplifies
programming. Blocks are code blocks which can be passed as a parameter
to a method. Using this feature it is easy to build code libraries which can
delegate varying functionality to code blocks to be built later.
Implicit return value in methods - Value of the last expression in a
method becomes the return value of the method. In Ruby return keyword is
optional.
7. In Ruby everything is open! - In Ruby you can easily extend classes
and modules. This means that nothing in Ruby (including built in classes and
modules) are closed!. Interestingly additional methods can be added to a
class even at runtime.
Ruby supports parallel assignment - It is possible to change multiple
variables in a single assignment. The best example is the swapping of two
variable.
In Ruby strings are mutable - In Ruby it is possible to change a string
variable in place. Hence unlike Java, the same string literal when used
multiple times will point to different object instances.
True and false in Ruby - In Ruby only nil and false evaluate to false.
This means that everything else evaluates to true! Hence even the value 0
evaluate to true in ruby.
8. SIMPLE RUBY PROGRAM TO ADD TWO
NUMBERS
# define a function called addtwo with two parameters
def addtwo(a, b)
a + b; # return a + b
end
print "Please enter number 1 : "; # get the input from the console,
val1 = gets;
print "Please enter number 2 : ";
val2 = gets;
# convert the string console inputs to_i (to_integers) and add together
print "Answer : " , (val1.to_i + val2.to_i), "n";
9. JAvA vS RUBY !!
•Ruby is interpreted, Java is compiled (before being interpreted)
>ruby my_program.rb
• Code can be loaded at runtime
• Code is easily accessible
• Speed performance issues
>javac MyProgram.java
>java MyProgram
10. RUBY USE DYNAMIc TYPING
• Values have type, variables not
• Decrease language complexity
- No type declaration
- No type casting
• Increase flexibility
• Errors appears at run-time
14. ON A BUSINESS POINT Of vIEW ! !
• Java is a well-known technology
• Lots of developments have been made with it
• Easy to find experts
• Still not that much available Ruby developers
16. WHAT IS RAILS ??
Rails is a web-application framework that includes everything needed to
create database-backed web applications according to the Model-ViewControl pattern.
Ruby on Rails was extracted by David Heinemeier Hansson from his work
on Basecamp, a project management tool by 37signals (now a web
application company).
Like many contemporary web frameworks, Rails uses the Model-ViewController (MVC) architecture pattern to organize application programming.
17. WHAT IS A WEB FRAMEWORK ??
A web application framework is a software framework that is
designed to support the development of dynamic websites, Web applications
and Web services. The framework aims to alleviate the overhead associated
with common activities performed in Web development.
For example, many frameworks provide libraries for database access,
templating frameworks and session management, and often promote code
reuse.
Some of the main features of web framework is that they provide
security,database access and mapping,URL mapping,Web template
system,caching,AJAX ,Automatic Configurations and so on.
18. MVC ARCHITECTURE
Model–view–controller (MVC) is an architectural pattern used in
software engineering. The pattern isolates business logic from input and
presentation, permitting independent development, testing and maintenance
of each.
These frameworks use actions that do the required processing, and then
"push" the data to the view layer to render the results. These frameworks
start with the view layer, which can then "pull" results from multiple
controllers as needed.
19. MODEL- Used for persistence and relationships.
VIEW- Used for displaying the data.
CONTROLLER- The logic of the application.
20. FEATURES OF RUBY ON RAILS
Ruby on Rails is separated into various packages, namely ActiveRecord(an
object-relational mapping system for database access), ActiveResource
(provides web services), ActionPack , ActiveSupport and ActionMailer.
Prior to version 2.0, Rails also included the Action Web Service package
which is now replaced by Active Resource.
Apart from standard packages, developers can make plugins to extend
existing packages.
22. RAILS VS J2EE
Both have a learning curve.
RAILS has the edge in productivity by a significant margin.
J2EE currently has an edge in scalability. If it’s a client facing system for
millions of concurrent users – use J2EE.
If it’s an internal web application, definitely take a look at this technology as
a possible way of shortcutting the long development time for a J2EE web
application.
24. AppLICAtIOnS OF ROR !!
Ruby On Rails have been in use now by over 500 websites.
Some of the leading websites using
yellowpages.com, lumosity.com and so on.
RoR
are
43things.com,
Ruby on Rails is Picking up the pace and have become more and more
viable in the business scenario.
25. COnCLuSIOn
RoR an evolving Toolset.
Ruby is what makes Rails special, the interest in general Ruby
programming will continue to expand rapidly
RoR can be best used for small web based applications requring
parallel development.
