Over the last few years, Airbnb’s frontend architecture has evolved to keep pace with the rapid advancement happening the JavaScript world. Starting as a humble Rails 2 + Prototype.js app in 2008, the frontend stack powering airbnb.com has gone through a few revisions, including a push towards single-page app architecture with Backbone.js and Handlebars.js, an adventure into isomorphic JavaScript with Rendr (our library for using Node.js to server-render Backbone SPAs), and most recently, a move toward React.js and a re-envisioning of our build pipeline to take advantage of CommonJS, ES6, and a Node.js-based transform system. Spike Brehm, software engineer on the @AirbnbNerds team, will walk through how we approached and executed on these changes. Plus, get excited to see a preview of our new approach to isomorphic JavaScript, allowing us to server-render React components from our Rails app.
Spike Brehm is a software engineer at Airbnb who specializes in building rich web experiences. As a JavaScript nerd, he has spent the last few years shipping web apps and prototyping Airbnb’s front-end stack, experimenting with “isomorphic JavaScript” — apps that have the flexibility to run on both the client and sever using the same codebase.
I prepared this presentation to introduce Ruby on Rails to
a group of students at Università di Catania.
It is not enough to get a good grasp of Rails, the
presentation in fact was supported by live coding, where
I started created a Phrasalbook (no more blog engine

Have you ever cried yourself to sleep unable to find the cause of a horrendous bug in your node app? Cry no more, your tears will be reshaped into blinding swords as we explore uncharted territories laced with mystical creatures.
JavaScript debugging is an often avoided topic due to the uncertainty of how best to accomplish it and the lack of powerful introspective tools. This talk will explore new territory and showcase tools that help you debug complex and difficult issues in your node or frontend app. Libraries and tools such as node-inspector, Time-Travel Debugging, Visual Studio Code, vorlon.js, Vantage and memory leak catchers will be used to slay dragons.
No more shall you fear building complex apps with JavaScript!
An Intense Overview of the React EcosystemRami Sayar
React has been named the front-end library to learn in 2016 however few people talk about the React without mentioning Flux (or Redux or React Native or Relay). In this talk, we will explore the ecosystem of tools and libraries that surround React. We will look at the various Flux implementations (including a short explanation of Flux) like Redux, at react-router, at some of the reactive database or reactive API libraries and finally at everyday tools and techniques that make the React developer happy. By the end of this talk, you will have a greater grasp of the ecosystem and leave with new tools in your developer arsenal.
This session introduces the Spring Web Scripts and the Spring Surf framework describing how they are used to underpin the Alfresco Share user interface. As well as covering the basic concepts, this session will cover the history and future roadmap for the frameworks.
If you are new to Single Page Applications, This will give you a great understanding of a proven technology stack & Architecture used in a popular commercial project.

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 a powerful and popular web
development framework that has transformed the way we build web
applications.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Θωμάς Ασίκης
Κωνσταντίνος Σταύροσ
2. AN INTRODUCTION…
Some general things:
o Ruby is the programming language.
o Rails is a Web Development
Framework on top of Ruby.
3. ABOUT RUBY
Ruby is:
o Dynamic – executes on runtime.
o Reflective – modifies itself on runtime.
o General purpose – can be used for any
programming purpose.
oOpen Source…
o Object oriented…
o High-Level…
4. THE RUBY STORY
Developed in the early-1990s.
Created by Yukihiro "Matz" Matsumoto.
Originates from Japan.
First released on February 1995.
Next major release, Ruby 2.0
expected on 2013.
5. TECHNICAL INFO
Interprets to C.
Uses the best practices from Perl, Smalltalk, Eiffel, and Lisp.
Ruby follows the principle of least astonishment (POLA).
Works as expected.
Alternative implementations of Ruby,
including YARV, JRuby, Rubinius, IronRuby,
MacRuby, and HotRuby.
6. INSTALLING RUBY
Depending on tour system there are
many different installation ways.
The 3 basic Ways are:
1. You can compile it from source.
2. You can install it through 3rd party
tools, RVM – Linux/MacOS,
Ruby Installer – Windows.
3. Via package managers:
Apt-get install, yum install,
brew install, pacman –S etc.
7. FILE EXTENSIONS
The most popular file extensions of Ruby (and also
Rails) files are:
o .rb the Ruby class files.
o .gem Ruby package files that may contain
Ruby programs and libraries.
o .yml data mapping files.
o .html.erb Ruby html files.
8. DO YOU SPEAK RUBY?
Ruby is a scripting language, which has one
goal:
To be programmer friendly.
So it's expressive, and closer to physical
language.
9. SOME RUBY TALK
Something no one ever seen before…
Let’s do an innovative Hello World example:
puts "Hello World!"
10. RUBY LOGIC
In Ruby Everything is an object. There are no
primitive types. Lines and | are code seperators.
No need to declare variable types. For exampe:
@name #a variable
@name = 2 #a number
@name = “Kaiser Chiefs” #a String
@name = 1..52 #a range
@name = [“Rails”,12,[6,7,9],3..53]
#a collection
11. RUBY LOGIC AGAIN
A class example
class Person
attr_accessor :name
end
Class instance Example
bob = Person.new
bob.name = “Bob the Builder”
Blocks example – blocks are anonymous functions
workers = [Bob, Maria, George, Sylvia]
for person in workers do
puts person.name
end
workers.each do |person|
puts person.name
end
12. RUBY LOGIC AGAIN AND AGAIN
Iterrators example
best_workers = workers.select{|person|
person.name.include? ”a”}
Hashes are a great way to store things:
Hash example
fav_djs = {“tiesto” => 8, “deadmau5” => 6,
“kaskade” => 3, “benassi” => 7}
fav_djs[“deadmau5”] >> 6
fav_djs[“benassi”]+=2 >> 9
fav_djs[“afrojack”] = 5
13. HOW TO HACK SOMETHING USING RUBY…
Now we know enough to…
14.
15. SO? WHAT’S RAILS?
•Open source
• MVC Web Framework
•Optimized for programmer happiness.
•Developed for database backed
web applications,.
•Very AGILE
16. FOR STARTERS
Rails is a ruby web framework.
It was designed by David Heinemeier Hansson.
Was released as an open source project on 2004.
And joined Mac on 2007.
18. SOMETIMES PICTURES AREN’T ENOUGH
• This pattern splits the view (also called the presentation) in
"dumb" templates that are primarily responsible for inserting
pre-built data in between HTML tags.
• The model contains the "smart" domain objects (such as
Account, Product, Person, Post) that holds all the business
logic and knows how to persist themselves to a database.
• The controller handles the incoming
requests (such as Save New Account,
Update Product, Show Post) by
manipulating the model and directing
data to the view.
19. RAILS FIGHTS FOR
Write Less Do More.
DRY – Don’t Repeat Yourself.
COC – Convention over Configuration.
REST- Representational State
Transfer.
21. RAILS CAPABILITIES
•ORM : Object Relational Mapping.
•CRUD: Create Read Update Delete
a Database.
•Both BDD and TDD: Behavior and Test Driven
Development.
•Ajax and Web Services.
•Meta Programming.
22. WHAT IS ORM?
Active Record (ORM)
An ORM layer built-in maps classes to tables so :
•Every row is an object.
•Every column is an object attribute.
Also it uses conventions to minimize
configuration.
23. COMPATIBILITY
Most Platforms :
Linux, Windows, MacOs etc.
Most Databases :
MySQL, Sqlite, NoSQL etc.
A lot of Web Servers :
Nginx, Apache, Passenger etc.
25. GETTING STARTED
All Rails Apps use the same
structure.
No matter the editor or IDE you
are using, the projects have
the same build.
The newer versions always
support the older.
27. DEVELOPER TOOLS
Editors: vim, gedit, Textmate
and more
IDEs: RubyMine, Eclipse with
plugin, Aptana, Radrails,
3rdRail
28. GETTING STARTED
