Drupal as a Rapid Application Development (RAD) Framework for StartupsZyxware Technologies
The presentation is about why Drupal is a good choice as a framework to build your next big product / service idea if you are a startup. The presentation covers the reasons and also introduces concepts in Drupal that will allow a startup to get their web application up and running without writing a line of code. Then again the idea is to never write a line of code but also about picking a platform where you can get started fast and then build and customize later.

A Public Cloud Based SOA Workflow for Machine Learning Based Recommendation A...Ram G Athreya
Over the past decade the field of Cloud Computing has been the focus of intensive research. In this paper we propose a framework that will simulate the architectural setup of a cloud environment and examine how it can leverage Apriori and Sequential Pattern based recommendation algorithms through R. Furthermore, we present a multi layered application encompassing its backend architecture, user interface built using the responsive web design technique and its development workflow. The proposed system was also exhaustively load tested using Apache JMeter to ensure its reliability at scale and the experimental results are presented.
Forecasting a Student's Education Fulfillment using Regression AnalysisRam G Athreya
Our government spends substantial amount of resources in educating our children. Additionally several welfare schemes are introduced aimed especially at underprivileged children to ensure that all of them complete a basic level of education. In spite of these measures many students do not complete their basic education.
The aim of this project is to formulate a Supervised Learning Algorithm that will aid in identifying such students who have a higher likelihood of not completing their education.
To perform this task the algorithm will perform Logistic Regression Analysis on historical data of students from a given school. The historical data includes basic background information (features) such as gender, community, number of siblings etc. It must be noted that the historical data also contains information on whether the student completed his/her education, which is the outcome we are interested in. Typically a student finishing education will be denoted using a value of 1 and a student not finishing will be denoted with a value of 0.
Based on the training (historical) data a logistic classifier can be built. Such a classifier after learning from the training set will develop specific weightages for each of the features. These weightages can then be extrapolated into an equation that can be used for prediction.
That is we can apply the equation on a current student (whose background we already know) to calculate the probability that he/she will complete his/her education.
Such an algorithm will be beneficial to government agencies since it can serve as an early warning system using which they can take more proactive action to prevent a student from dropping out. Policy makers can also use it as a tool to identify schools that are more vulnerable and direct their resources and energies to help them.
Semi-Automated Security Testing of Web applicationsRam G Athreya
Market research survey on Internet attacks reports that more than 70% of the attacks are on the application layer. This is because 1. More valuable information (electronic money details) is at the application level and 2. Relatively there are more unaddressed vulnerabilities. Considering the fact that there are still inadequate adoption of security development practices across the numerous application development communities, the security testing of the web applications becomes highly critical and rigorous.
In our project we have created a penetration testing tool (Black Box Testing Tool) that will check for vulnerabilities in a semi – automated fashion on a target web application. We have tested and demonstrated the functionality and effectiveness of our tool by running this tool on 1. On a target vulnerable web application created by us and 2. On live web sites of a customer organization. The results have been revealing and have been documented appropriately in the following report. We have also provided recommendations as part of corrective action against the discovered vulnerabilities and statements of best practices based on ISO27002 and such other organizations as a preventive action in order to avoid recurrence of such vulnerabilities.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

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.

2. Why is Web Dev important
– More and more major businesses and industries are
being run on software and delivered as online services
(Web Applications)
– Six decades into the computer revolution, four
decades since the invention of the microprocessor,
and two decades into the rise of the modern Internet,
all of the technology required to transform industries
through software finally works and can be widely
delivered at global scale.
– In 2000 cost of running a Web Application was
$150,000 now it is around $1,500 a month
• Why Software is eating the world(By MARC
ANDREESSEN)
3. Why is Web Dev important
– The world’s largest retailer today is Amazon its
core capability is software (not procurement or
supply chains etc)
– Largest video service is Netflix (in US) which is also
a Software Company not a Cable related company
– Major music companies are Spotify & iTunes not a
record label
4. The List goes on
• Retail – Amazon Software
• Communication – Whatsapp, Facebook
• Games – Zynga, Rovio
• Entertainment – Spotify, iTunes, Pandora,
Netflix
• Photography – Flickr
• Advertising/Marketing – Google
• Telecom – Skype
• Recruiting – Naukri, LinkedIn, Monster
5. Also Physical Industries
• Cars – Android Auto, Apple AirPlay
• Real World Retailer – Wal-Mart (its core is S/W)
• Marketplaces – EBay
• Couriers – FedEx & UPS (powered by S/W &
smart analytics)
• Banks – All banks have moved online
• Healthcare & Education are next on the list
• Health – Fitness apps, Healthkit & wearables
• Education – Online platforms (Coursera, Udemy)
6. Challenges
• First of all, every new company today is being
built in the face of massive economic
headwinds, making the challenge far greater
than it was in the relatively benign '90s.
• Secondly, many people in the U.S. and around
the world lack the education and skills
required to participate in the great new
companies coming out of the software
revolution.
7. Agenda
• Cover the whole spectrum of web application
development
• Current cutting edge technology that is widely
used
• Suitable example that will make
understanding easier
8. Problem Statement
• Develop a single page stock market app
• Features
– Search Bar
– Current stock price & G/L
– Graph
– Additional details such as Volume etc
– News related to the stock
– Send to E-Mail
• Ideally should also work in mobile
11. Web Dev Architecture
• Backend
– Handle HTTP Requests & generate responses
– Communicate with database
– Communicate with third party APIs
• Frontend
– Communicate with server
– Display content from server responses
– Presentation of content & user interactivity
20. Why we need a Web Framework
• MVC Architecture
• URL Mapping
• Web Templates & theming
• Easy Database Connectivity
• User management
• Data Persistence
• Security
• Caching
24. Application
• The application object encapsulates the
execution context within which a request is
processed
• Its main task is to collect some basic
information about the request, and dispatch it
to an appropriate controller for further
processing.
29. ORM
• Object-relational mapping in computer
software is a programming technique for
converting data between incompatible type
systems in object-oriented programming
languages. This creates, in effect, a "virtual
object database" that can be used from within
the programming language.
30. ORM
• Student Table
– Student ID
– Name
– Teacher ID
• Teacher Table
– Teacher ID
– Name
31. ORM
class student{
public $student_id;
public $name;
public $teacher_id;
public function rules(){
return array(
array(’name', 'validateName'), // Custom validation method
in this object);
}
public function relations() {
return array(
’Teacher' => array(self::HAS_MANY, ’teacher',
’teacher_id'),
);
}
}
33. Active Record
• Active record is an architectural pattern found
in software that stores its data in relational
databases.
• A database table or view is wrapped into a
class
• This pattern is commonly used by object
persistence tools, and in object-relational
mapping (ORM)
• Typically, foreign key relationships will be
exposed as an object instance of the
appropriate type via a property.
35. User management
• Yii provides built in user management, access
control & authentication mechanisms
• By default a user table can used to provide
access to users
63. Importance of UI/UX
• The goal of user interface design is to make
the user experience and interaction with your
system as simple and efficient as possible
• A good experience leads to more user
satisfaction & better conversions or purchases
64. Fedex Logo
• Won over 40 design awards
• Rated as one of the best designs focusing on
negative space
• Once you understand the significance you will
never forget the brand
75. Inheritance
• Prototypal inheritance i.e there are no classes
• Instead the focus is on objects
• You start by making a useful object. You can
then make many more objects that are like
that one.
• So once we have an object that we like, we
can make more instances with the
Object.create() method
88. Recap
• Understood why web development is
important
• Defined a problem to delve deeper into this
field
• Overview on Backend Development
• Overview on Frontend Development
• Web Debugging
90. localStorage
• Easy mechanism to store data within the
browser
• More secure & faster than cookies
• Data stored as key/value pairs
• Data is domain specific
91. Application Cache
Application cache gives three advantages
• Offline browsing - users can use the
application when they're offline
• Speed - cached resources load faster
• Reduced server load - the browser will only
download updated/changed resources from
the server
93. Manifest File
Manifest file has 3 sections
• CACHE MANIFEST - Files listed under this header
will be cached after they are downloaded for the
first time
• NETWORK - Files listed under this header require
a connection to the server, and will never be
cached
• FALLBACK - Files listed under this header specifies
fallback pages if a page is inaccessible
95. Geolocation
• The HTML5 Geolocation API is used to get the
geographical position of a user.
• Since this can compromise user privacy, the position is
not available unless the user approves it.
96. Responsive Web Design(RWD)
Motivations
• RWD is a web design approach aimed at
crafting sites to provide an optimal viewing
experience
– easy reading and navigation
– minimum of resizing, panning, and scrolling
– across a wide range of devices (from mobile
phones to desktop computer monitors)
97. RWD Approach
• The fluid grid concept (percentages over
pixels)
• Flexible images
• Media Queries
102. CDN
• A content delivery network or content
distribution network (CDN) is a large
distributed system of servers deployed in
multiple data centers across the Internet.
• The goal of a CDN is to serve content to end-
users with high availability and high
performance.
126. Heroku
• Heroku is a cloud platform as a service (PaaS)
supporting several programming languages
• Heroku was acquired by Salesforce.com in
2010
• The base Operating System is Debian based
Ubuntu(LINUX)
• Provides an easy to use platform for deploying
