Refactoring for Software Architecture Smells - International Workshop on Refa...Ganesh Samarthyam
Code smells and refactoring have received considerable interest from the academia as well as from the industry in the past two decades. The interest has given birth to various tools, processes, techniques, and practices to identify smells and refactor them. Despite the high interest, architecture smells and corresponding refactorings haven't received as much focus and adoption from the software engineering community. In this presentation, we motivate the need of architecture refactoring, discuss the current related research, and present a few potential research directions for architecture refactoring.
Open Source Data Annotation Platform for NLP, CV, Tabular, and Log DataAll Things Open

Abstract: We introduce Data Annotator for Machine Learning (DAML), a data annotation platform to create high-quality labelled datasets for supervised machine learning. This all-in-one platform helps machine learning teams collaborate on the creation and management of data annotation projects to quickly build custom training datasets while maintaining data quality. The tool works for all major file types, Text, Tabular, Image, Named Entity Recognition & Log data, and uses Active Learning to intelligently querying annotators to label the data that matter the most, therefore reducing the amount of labeled data to achieve similar accuracies.
Worse is better, for better or for worse - Kevlin HenneyJAX London
Over two decades ago, Richard P Gabriel proposed the thesis of "Worse Is Better" to explain why some things that are designed to be pure and perfect are eclipsed by solutions that are seemingly limited and incomplete. This is not simply the observation that things that should be better are not, but that some solutions that were not designed to be the best were nonetheless effective and were the better option. We find many examples of this in software development, some more provocative and surprising than others. In this talk we revisit the original premise and question in the context of software architecture.
We presented this library at Java Developer Conference Cairo 2012. The purpose of this library is to provide developers with the capability to do Data Driven Testing on Android.

Good quality code is an essential property of a software because it could lead to financial losses or waste of time needed for further maintenance, modification or adjustments if code quality is not good enough.
The presentation discusses software design. It discusses the characteristics of a good and bad design. Then it talks about how to achieve a good design. Then finally we discuss the SOLID Principles of Object Oriented Design. These are 5 principles compiled by Rober Cecil Martin aka Uncle Bob. The benefit of these principles is to achieve a good OO design which is high in cohesion and low in coupling thus easily adaptable to change

Software Engineering class on main refactoring techniques and bad smells reported in the famous Fawler's book on this topic!
Can you release a new version of your product right now? This version includes everything which is under your version control? We don’t have to be hypocrite, answer yes to these two questions is not easy. In this lecture I’m going to talk about my journey in Continuous Delivery where I’ve find the fear as the biggest smell in its adoption.
Unit testing is mostly a solved problem, but how do you write tests for the visual side of your app—the part that your users actually see and interact with? How do you stop visual bugs from reaching your users?
We will dive deep into visual regression testing, a fast-growing technique for testing apps pixel-by-pixel. We will integrate perceptual diffs in Rails feature specs, and learn how to visually test even complex UI states. We will show tools and techniques for continuous visual integration on every commit, and learn how to introduce team visual reviews right alongside code reviews.
This talk was given by Priti Biyani and me at XP Conference, Bangalore 2015. It basically talks about non-deterministic tests and the problems due to these tests. It also outlines the causes and solutions to solve this problem.
This is a short preview of a talk I will giving at Agile Testing Days 2014
The rise of Distributed Version Control Systems with good merge support has rehabilitated Feature Branches with many Open Source projects (OSS) receiving contributions as Pull Requests. Feature Branching is a technique where developers do all their changes separate from the mainline of code. Next they open a Pull Request to have their code merged into the mainline after being peer reviewed.
This OSS popularity for Pull requests with Git and Mercurial has been transferring to commercial projects, with many teams now adopting it internally. SCM is seen as a Developer centric domain but testers have a lot to gain. This presentation will cover an introduction to Pull Requests and demonstrate how to identify key information that can be used to as inputs to different testing techniques.
While not a direct substitute for pairing with a developer, pull requests represent an opportunity to review the code, automated testing and learn from the developers by asking questions. As each Pull Request represents a single User Story this information can help limit the scope of Exploratory based testing sessions and be utilized to further understand the risk of the changes to the system.
Feature Flags Are Flawed: Let's Make Them BetterStephen Young
An introduction to Feature Flags, canary deployments and finally, Swivel: A PHP library that will manage cohorts and features automatically for the developer.
Feature Flagging to Reduce Risk in Database Migrations LaunchDarkly
I won’t say that feature flagging your database migration will make everything easy, but it will make it easier to test it with real, live data (for a subset of your user base), and much easier to roll it back if something goes wrong. I will explain how you can use feature flags to gradually apply a database migration or schema change, while constantly verifying that the new model passes integrity checks. This ensures that the migration can be applied in a controlled manner, with very little risk.
Slides were used for the session on 'Feature toggles' on ATAGG(2014)
Abstract - Is your code Toggled !?!
What is Agile?
According to Agile manifesto principles, Agile is
“Customer satisfaction by rapid delivery of useful software”, “Working software is delivered frequently (weeks rather than months)”. In most of agile teams, multiple features are worked upon by sub-teams in same sprint/iteration. Even though it enables rapid delivery, if not planned well teams may find it challenging to release work of one sub-team while withholding the others. Or worse, release gets delayed as part of work (any single team) is not production-deployable. Rapid delivery by multiple streams becomes unreality as delivery time grows from weeks to months.
Generally, most teams use multiple branches to manage this challenge to an extent. This strategy, consumes lot of time in integration & regression testing cycles every sprint. Could there be better solution? What if we could save the time we spend on these regression cycles? Think of solution where there is single branch to commit to, and everything is released to staging/production, but features are ”Toggled” depending on their usability/need. This talk explores a concept called “Feature Toggles” and how it could help us make test cycles short.
Talk emphasizes on effectively managing multiple streams, without delaying the delivery of software. It mainly focuses on various useful techniques (Branching, Feature Toggles etc.) which can help agile teams with multiple sub-teams to efficiently manage their codebase & releases to achieve faster delivery.
Feature flags to speed up & de risk developmentLaunchDarkly
Feature flags are a continuous delivery best practice. Feature flags, gating features and being able to quickly reverse features enables development teams to ship more frequently. Learn how to use feature flags for opt-in early access, private beta, canary launches and dark releases. This talk will use a mix of case studies and best practices and will appeal to software teams who want to move faster and deliver features to end users quicker.
Feature Toggle - What Why and How A technique that allows you to “switch on” or “switch off” features of a product. So till the time the entire story is ready to be released the feature is marked as “switched off”. So though everything that is being developed is in the trunk but it is not visible and is not executed till the time it is “switched on”. There is a lot more to feature toggles and this session will allow you to think away from the conventional approach of Branching and Merging and move towards CI/CD efficiently.

Emergent Design & Evolutionary Architecture
Most of the software world has realised that Big Design Up Front (BDUF) doesn’t work well in software. But lots of developers struggle with this notion when it applies to architecture and design, surely you can’t start coding, right? You need some level of understanding before you can start work.
This seminar will explore the current thinking about Emergent Design and Evolutionary Architecture, including:
• Proactive approaches with test driven development
• Reactive approaches including both refactoring and composed methods
• Strategies and techniques for allowing design to emerge from projects as they proceed, keeping your code in sync with the problem domain
• Real world examples of these techniques in action

Commands, events, queries - three types of messages that travel through your application. Some originate from the web, some from the command-line. Your application sends some of them to a database, or a message queue. What is the ideal infrastructure for an application to support this on-going stream of messages? What kind of architectural design fits best?
This talk provides answers to these questions: we take the *hexagonal* approach to software architecture. We look at messages, how they cross boundaries and how you can make steady communication lines between your application and other systems, like web browsers, terminals, databases and message queues. You will learn how to separate the technical aspects of these connections from the core behavior of your application by implementing design patterns like the *command bus*, and design principles like *dependency inversion*.

"The Intersection of architecture and implementation", Mark RichardsFwdays
A common saying by software architects is “that’s an implementation detail”. All too often we treat software architecture and implementation as two separate things, where implementation is something that happens once a software architecture is defined. In fact, it’s the other way around: software architecture should be viewed as a first draft, where implementation reveals more details and refinements. In this provocative keynote Mark Richards discusses the intersection of architecture and implementation, and how the two must be in constant alignment to achieve success. Through real-world examples, he shows how implementation can get out of alignment with the architecture, causing the system to fail to achieve its desired goals. He then shows some techniques and tools to help ensure alignment between architecture and implementation.
Almost everything can be done using refactoring tools:
* How to get buy-in for refactoring? (use Technical Debt quantification tools)
* How to identify refactoring candidates? (use smell detection tools)
* How to prioritize / identify what to refactor first? (use reports from design analysis tools)
* How do I identify dependencies and evaluate impact of refactoring? (use visulization tools)
* How to I actually perform refactoring? (Use IDE support for automated refactoring and use them!)
Deriving from a rich experience in using tools for refactoring in real-world projects, this talk takes you through a whirl-wind tour of refactoring tools (of course for Java). What's more, this talk includes quick demos of some of these tools so you can see them in action.

I have been fortunate to have worked with some geeks with incredible coding skills. I felt amazed at how they can play games with compilers, perform magic with their incantations on the shell, and solve some insanely complex algorithm problems with ease. I naively assumed that they are going to achieve greatness in near future. Alas, I was wrong. Really wrong. [Read the rest of the article ... ]

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.
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.
Code reviews are vital for ensuring good code quality. They serve as one of our last lines of defense against bugs and subpar code reaching production.
Yet, they often turn into annoying tasks riddled with frustration, hostility, unclear feedback and lack of standards. How can we improve this crucial process?
In this session we will cover:
- The Art of Effective Code Reviews
- Streamlining the Review Process
- Elevating Reviews with Automated Tools
By the end of this presentation, you'll have the knowledge on how to organize and improve your code review proces

SOCRadar Research Team: Latest Activities of IntelBrokerSOCRadar
The European Union Agency for Law Enforcement Cooperation (Europol) has suffered an alleged data breach after a notorious threat actor claimed to have exfiltrated data from its systems. Infamous data leaker IntelBroker posted on the even more infamous BreachForums hacking forum, saying that Europol suffered a data breach this month.
The alleged breach affected Europol agencies CCSE, EC3, Europol Platform for Experts, Law Enforcement Forum, and SIRIUS. Infiltration of these entities can disrupt ongoing investigations and compromise sensitive intelligence shared among international law enforcement agencies.
However, this is neither the first nor the last activity of IntekBroker. We have compiled for you what happened in the last few days. To track such hacker activities on dark web sources like hacker forums, private Telegram channels, and other hidden platforms where cyber threats often originate, you can check SOCRadar’s Dark Web News.

Developing Distributed High-performance Computing Capabilities of an Open Sci...Globus
COVID-19 had an unprecedented impact on scientific collaboration. The pandemic and its broad response from the scientific community has forged new relationships among public health practitioners, mathematical modelers, and scientific computing specialists, while revealing critical gaps in exploiting advanced computing systems to support urgent decision making. Informed by our team’s work in applying high-performance computing in support of public health decision makers during the COVID-19 pandemic, we present how Globus technologies are enabling the development of an open science platform for robust epidemic analysis, with the goal of collaborative, secure, distributed, on-demand, and fast time-to-solution analyses to support public health.
Listen to the keynote address and hear about the latest developments from Rachana Ananthakrishnan and Ian Foster who review the updates to the Globus Platform and Service, and the relevance of Globus to the scientific community as an automation platform to accelerate scientific discovery.
Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
10. "... a delightful, engaging, actionable read... you have
in your hand a veritable field guide of smells... one
of the more interesting and complex expositions of
software smells you will ever find..."
- From the foreword by Grady Booch (IBM Fellow and Chief Scientist for
Software Engineering, IBM Research)
11. "This is a good book about ‘Design Smells’ – actually
a great book – nicely organized - clearly written with
plenty of examples and a fair sprinkling of
anecdotes."
- Will Tracz (Principal Research Scientist & Fellow, Lockheed Martin)

22. Discussion Example
// using java.util.Date
Date today = new Date();
System.out.println(today);
$ java DateUse
Wed Dec 02 17:17:08 IST 2015
Why should we get the
time and timezone details
if I only want a date? Can
I get rid of these parts?
No!
23. So What!
Date today = new Date();
System.out.println(today);
Date todayAgain = new Date();
System.out.println(todayAgain);
System.out.println(today.compareTo(todayAgain) == 0);
Thu Mar 17 13:21:55 IST 2016

false
What is going
on here?
27. Refactored Example …
You can use only date,
time, or even timezone,
and combine them as
needed!
LocalDate today = LocalDate.now();
System.out.println(today);
LocalTime now = LocalTime.now();
System.out.println(now);
ZoneId id = ZoneId.of("Asia/Tokyo");
System.out.println(id);
LocalDateTime todayAndNow = LocalDateTime.now();
System.out.println(todayAndNow);
ZonedDateTime todayAndNowInTokyo = ZonedDateTime.now(ZoneId.of("Asia/Tokyo"));
System.out.println(todayAndNowInTokyo);

35. Language Features & Refactoring
public static void main(String []file) throws Exception {
// process each file passed as argument
// try opening the file with FileReader
try (FileReader inputFile = new FileReader(file[0])) {
int ch = 0;
while( (ch = inputFile.read()) != -1) {
// ch is of type int - convert it back to char
System.out.print( (char)ch );
}
}
// try-with-resources will automatically release FileReader object
}
public static void main(String []file) throws Exception {
Files.lines(Paths.get(file[0])).forEach(System.out::println);
}

37. Refactoring Windows!
“A large number of dependencies at the module level
could be reduced and optimized to:
* make modular reasoning of the system more efficient
* maximize parallel development efficiency
* avoid unwanted parallel change interference
* selectively rebuild and retest subsystems effectively”
Refactoring performed to reduce
and optimize dependencies - by
creating and enforcing layering
