Fiverr - delivering fast w/ no QA - Agile Israel 2016 Gil Wasserman
This document discusses Fiverr's approach to quality assurance called "NoQA" where QA is removed from the critical path of software development in order to allow for faster delivery of features. Some key aspects of Fiverr's NoQA approach include:
- Removing QA from being a gatekeeper and instead integrating QA as part of the development team
- Relying on developers to test their own code through techniques like unit testing and deployment to staging environments
- Focusing on continuous monitoring of production systems to identify issues once features are live
- Guiding principles of trust, autonomy, ownership and accountability to replace formal QA processes
- Embracing uncertainty and continuous learning as software development is viewed as an ongoing knowledge game

Getting out of the monolith hell
The document discusses moving away from monolithic architecture as a system grows larger. It identifies that while monolithic architecture is simple initially, it becomes difficult to work with as the codebase and system grow in size. This leads to issues like slow delivery, inability to scale the system or team, and difficulty adopting new technologies.
The document then discusses distributed systems using microservices as an alternative approach. It covers concepts like identifying business capabilities, integrating services using APIs or messaging, and common integration patterns. Finally, it identifies some pitfalls to avoid with microservices like having too many "nano services" that fragment logic and management overhead. The overall goal is to speed up delivery, scale the system and team, and increase u

Road to Async Nirvana
This document discusses using React hooks and the React Query library to manage asynchronous data fetching and state in React functional components. It begins by explaining how hooks like useState and useEffect allow adding local state and side effects to functional components. It then introduces React Query, a library that abstracts away asynchronous data fetching, handles loading states, and caches results. React Query exposes hooks that components can use to fetch data from a centralized cache. The document discusses how React Query handles common concerns like loading states, errors, and dependencies between queries. It concludes by discussing how Suspense can be used to declaratively wait for asynchronous data and show loading states.
ReactiveConf - Not all indecision are bad
Boris Litvinsky discusses how indecisions are not always bad. He outlines 4 things that can be deferred in a project including estimations, installing packages, creating abstractions, and breaking a monolith. Litvinsky also discusses the "Jedi code" of real options which allows deferring decisions until their value expires. Test driven development, spikes, and using a "modular monolith" are enablers for creating options. While deferring decisions can be useful, it also has costs such as removing alternatives and increasing complexity. Litvinsky's key takeaways are to not commit early unless necessary, create options to defer decisions, and be aware of the costs of deferring.

Your IDE Deserves Better
The Web is a futuristic masterpiece, but it's being written using stone-age tools. Code-editor vendors just don't stand a chance in keeping up with the rapid evolution of the Web development scene. In this talk, we’ll learn how to build an extension that will give your editor new and powerful capabilities, and we'll do it using the knowledge you already possess - Javascript!
The ultimate guide for Software Procrastination
Software development is a process comprised of decisions made by the developers. But despite the the fact that some decisions can have a long-lasting, crippling effects on our app, we make most of them based on guesses.
But what if the best decision is indecision? What if You could postpone most of your decision until you gather enough facts in order to make the optimal one?
In this talk, we will learn why deferring decisions can result in a much better, simpler code base. We’ll see examples of decisions we think we have to take on day 1 of the project, yet, can (and should) be postponed and see how practices like Spikes and the right design of your application will allow that to happen.
CDD @ FED
The flood of tools and frameworks in the front-end development world caused both the developers and their employers to lose sight of the things that really matter - software craftsmanship. It’s demand for Angular over TDD, SASS over SOLID. This loss of focus from the essentials is in the long run damaging and sadly - it is all self-inflicted. In this talk we will go over the long-term effects and explore solutions.
Name in Vain: Improving design one word at a time
The document discusses the importance of naming in code. It states that naming matters as it signifies potential problems in design and shortens the learning curve. It also discusses different types of bad names like vague names that don't express a role, abbreviations that are ambiguous, names that are too long to remember, and names that include unnecessary context. The document emphasizes that names should reference terms from the domain model and be written like well-written prose using classes as nouns, methods as verbs, interfaces as adjectives, and booleans as auxiliary verbs. It concludes with six reminders for good naming practices.

Atelier - Innover avec l’IA Générative et les graphes de connaissances
Allez au-delà du battage médiatique autour de l’IA et découvrez des techniques pratiques pour utiliser l’IA de manière responsable à travers les données de votre organisation. Explorez comment utiliser les graphes de connaissances pour augmenter la précision, la transparence et la capacité d’explication dans les systèmes d’IA générative. Vous partirez avec une expérience pratique combinant les relations entre les données et les LLM pour apporter du contexte spécifique à votre domaine et améliorer votre raisonnement.
Amenez votre ordinateur portable et nous vous guiderons sur la mise en place de votre propre pile d’IA générative, en vous fournissant des exemples pratiques et codés pour démarrer en quelques minutes.
A Study of Variable-Role-based Feature Enrichment in Neural Models of Code
Understanding variable roles in code has been found to be helpful by students
in learning programming -- could variable roles help deep neural models in
performing coding tasks? We do an exploratory study.
- These are slides of the talk given at InteNSE'23: The 1st International Workshop on Interpretability and Robustness in Neural Software Engineering, co-located with the 45th International Conference on Software Engineering, ICSE 2023, Melbourne Australia
Graspan: A Big Data System for Big Code Analysis
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
- Accepted in ASPLOS ‘17, Xi’an, China.
- Featured in the tutorial, Systemized Program Analyses: A Big Data Perspective on Static Analysis Scalability, ASPLOS ‘17.
- Invited for presentation at SoCal PLS ‘16.
- Invited for poster presentation at PLDI SRC ‘16.

SOCRadar's Aviation Industry Q1 Incident Report is out now!
The aviation industry has always been a prime target for cybercriminals due to its critical infrastructure and high stakes. In the first quarter of 2024, the sector faced an alarming surge in cybersecurity threats, revealing its vulnerabilities and the relentless sophistication of cyber attackers.
SOCRadar’s Aviation Industry, Quarterly Incident Report, provides an in-depth analysis of these threats, detected and examined through our extensive monitoring of hacker forums, Telegram channels, and dark web platforms.
Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
