Extreme Programming (XP) is an agile software development framework that focuses on rapid software development and frequent delivery of working software. It utilizes practices like pair programming, test-driven development, continuous integration, collective code ownership and small, frequent releases. The core values of XP include communication, simplicity, feedback and courage. An XP team consists of programmers, a customer representative, a coach and utilizes roles, practices and values to develop high quality software through collaboration and rapid, adaptive responses to changing requirements.

Periodic Table of Agile Principles and PracticesJérôme Kehrli
Recently I fell by chance on the Periodic Table of the Elements... Long time no see... Remembering my physics lessons in University, I always loved that table. I remembered spending hours understanding the layout and admiring the beauty of its natural simplicity.
So I had the idea of trying the same layout, not the same approach since both are not comparable, really only the same layout for Agile Principles and Practices.
The result is in this presentation: The Periodic Table of Agile Principles and Practices:

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
Modern design is crucial in today's digital environment, and this is especially true for SharePoint intranets. The design of these digital hubs is critical to user engagement and productivity enhancement. They are the cornerstone of internal collaboration and interaction within enterprises.
Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

2. 01 What is XP?
02 Why XP?
03 How and Who? : Roles and Practices in XP
04 Q & A
3. − Extreme Programming was created by Kent Beck, Ward Cunningham & Ron Jeffries in 1996.
What is Extreme Programming (XP) ?
Kent Ward Ron
4. “XP is a style of software development focusing on excellent application of
programming techniques, clear communication, and teamwork which allows us to
accomplish things we previously could not even imagine.”
-Extreme Programming Explained: Embrace Change, Second Edition
− "Extreme" means the practices get "turned up" to a much higher "volume"
than on traditional projects.
What is Extreme Programming (XP) ?
5. − Problems:
− Freeze all the requirements before starting design & development
− Resist changes: It will lengthen schedule
− Build a change control process to ensure that proposed changes are looked at carefully
and no change is made without intense scrutiny
− Increase the delay in Delivery and the Delivered product is obsolete on release
Why Extreme Programming (XP) ?
6. − XP recognizes that:
− All requirements will not be known at the beginning
− Requirements will change
− Use tools to accommodate change as a natural process
− Do the simplest thing that could possibly work and refactor.
− Emphasize values and principles rather than process
Why Extreme Programming (XP) ?
7. − Some other Benefits:
− As a Programmer:
− Get clear requirements & priorities
− Do a better job & make technical decisions
− Don’t work overtime
− Get accurate & timely feedback
− Customers:
− Get highest valued business item first
− Make informed business decisions
− If there is any need of change that can be communicated and implemented
Why Extreme Programming (XP) ?
13. − The Whole Team:
− Cross-functional team which can fulfill all the team’s roles.
− XP teams sit together in an open workspace.
− At the beginning of each iteration, the team meets for a series of activities: an
iteration demo, a retrospective, and iteration planning.
− This self-organization is a hallmark of agile teams.
Roles in XP
14. − On-Site Customer:
− On-site customer — often just called customer — is responsible for defining the software
the team builds.
− Typically, product managers, domain experts and business analysts play the role of the
on-site customer.
− Customers:
− Evangelize the project’s vision
− Identify features and stories
− Coordinating with Team and playing the planning game
− Customers themselves act as living requirements documents and providing it as needed
− Customers help communicate requirements by creating mock-ups, reviewing work in
progress, and creating detailed customer tests that clarify complex business rules.
Roles in XP
15. − Coach:
− A coach’s enables the team to succeed.
− Coaches help the team by arranging for a shared workspace and making sure that the
team includes the right people.
− Coach help in setting up conditions for energized work, and assist the team in creating
an informative workspace.
− Coaches help the team to interact with the rest of the organization. Coaches take
responsibility for any reporting needed.
− Coaches also help the team members maintain their self-discipline
Roles in XP
16. Fine scale feedback:
• Planning game
• Pair programming
• Test driven development
• Whole team
Shared understanding:
• Coding standard
• Collective code ownership
• Simple design
• System metaphor
Continuous process:
• Continuous integration
• Design improvement
• Small releases
Programmer welfare:
• Sustainable pace
Practices in XP
17. − The Planning Process : The main planning process within extreme programming is
called the Planning Game.
− It is a meeting that occurs once per iteration, typically once a week.
− The desired features of the software, which are communicated by the customer, are
combined with estimates provided by the programmers to determine what the most
important factors of the software are.
− Business writes a story describing desired functionality
− Stories are written on index cards
− Development estimates stories
− Velocity determines number of stories per iteration
− Business splits and prioritizes stories and determines the composition of releases
− Velocity is measured and adjusted every iteration
− Customer steers development
Practices in XP
19. − Pair Programming - All code is written by two programmers working at the same machine.
− Two roles: implementation(Driver) and strategy(Navigator)
− Driver has control over the workstation and is thinking mostly about the coding in detail.
− Navigator is more focused on the big picture, and is continually reviewing the code that
is being produced by Driver.
− Benefits:
− Continuous code review: better design, fewer defects
− Collective code ownership
− Discipline to always test and refactor
− Learn from partner’s knowledge and experience (enhances technical skills)
"Don't be afraid of Pair-Programming. You are not as good as you think , but your not as bad as you fear” - Ron
Jeffries
Practices in XP
20. − Test Driven Development – Testing is done consistently throughout the process.
− Unit Testing
− Test Driven Development (TDD)
− Acceptance Test Driven Development (ATDD)
− Programmers design the tests first and then write the software to fulfill the requirements
of the test.
− XP says that the programmer is finished with a certain piece of code when he or she
cannot come up with any further condition on which the code may fail.
− The customer also provides acceptance tests at each stage to ensure the desired results
are achieved.
Practices in XP
21. − Whole Team (On-Site Customer) - The XP project is directed by the customer who is
available all the time to answer questions, set priorities and determine requirements of the
project.
− And also defines the tests for “Acceptance Test driven development” (ATDD).
− Within XP, the "customer" is not the one who pays the bill, but the one who really uses
the system.
Practices in XP
22. − Continuous Integration (CI) - The XP team integrates and builds the software system
multiple times per day to keep all the programmers at the same stage of the development
process at once.
− It ensures that team is always working on the latest version of the software.
− Continuous integration will avoid delays later on in the project cycle, caused by
integration problems.
− There are various tools, some of these are:
− Hudson
− Jenkins
− Cruise Control
− Bamboo
Practices in XP
23. − Design Improvement (Refactoring) - XP programmers improve the design of the
software through every stage of development instead of waiting until the end of the
development and going back to correct flaws.
− XP advocates to refactor your code by changing the architecture, making it simpler and
more generic without changing the functionality.
− Continuously improve quality of the code
− Improves Performance & Readability
− Inbuilt practices of Unit Testing/TDD and Pair Programming give courage
Practices in XP
24. − Small Releases (Continuous Delivery) – The software is developed in small stages
that are updated frequently.
− It helps the customer to gain confidence in the progress of the project.
− It helps maintain the concept of the whole team as the customer can now come up with his
suggestions on the project based on real experience.
Practices in XP
25. − Coding Standard - The programmers all write code in the same way. This allows them to
work in pairs and to share ownership of the code.
− Coding standard is an agreed upon set of rules that the entire development team agree to adhere to
throughout the project.
− The standard specifies a consistent style and format for source code, within the chosen programming
language, as well as various programming constructs and patterns that should be avoided in order to
reduce the probability of defects.
Practices in XP
26. − Collective Code Ownership - Every line of code belongs to every programmer working on
the project, so there are no issues of proprietary authorship to slow the project down, in turn,
means that everybody is allowed to change any part of the code.
− Pair programming contributes to this practice.
− Collective ownership speeds up the development process, because if an error occurs in the code any
programmer may fix it.
Practices in XP
27. − Simple Design :
− Do the simplest thing that could possibly work
− Programmers should take a "simple is the best" approach to software design.
− Refactoring should also be used, to make complex code simpler.
− The software should include only the code that is necessary to achieve the desired results
communicated by the customer at each stage in the process.
− The emphasis is not on building for future versions of the product
− No duplicate code.
− Fewest possible classes and methods
Practices in XP
28. − System Metaphor - All members of an XP team use common names and descriptions to
guide development and communicate on common terms.
− It's a naming concept for classes/methods that should make it easy for a team member to guess the
functionality of a particular class/method, from its name only.
− It is a story that everyone - customers, programmers, and managers - can tell about how the system
works.
Practices in XP
29. − Sustainable Pace (40-Hour Week) - The XP team does not work excessive overtime to
ensure that the team remains well-rested, alert and effective.
− Key enabler to achieve sustainable pace is frequent code-merge, continuously integrated and always
executable & test covered high quality code.
− The intense collaborative way of working within the team drives a need to recharge over weekends.
Practices in XP
