Gute Software sollte sich an der entsprechenden Fachdomäne orientieren und nicht an der zugrundeliegenden Technologie. Um dies zu erreichen, wird allerdings eine Basis benötigt, die technisch ausgereift ist ohne Einschränkungen für die Entwicklung. Eine solche Basis kann mit dem Springframework geschaffen werden. Die Kombination von Spring, Annotations, Java Persistence (JPA) und Unit-Testing erlaubt eine flexible und modulare Architektur und könnte eine mögliche technische Basis für ein solches Softwaresystem sein. Dieser Vortrag stellt einen Lösungsansatz anhand eines einfachen Beispiels vor. Die Aufbereitung der Inhalte orientiert sich dabei an einem typischen test-zentrierten Entwicklungsprozess. Folgende Themen werden angesprochen: * Einleitung Spring und JPA, Maven, Groovy * Projektstruktur * Entwicklung der API (der Schnittstellen) * Test-getriebene Entwicklung der Implementierung * Spring-unterstützte Integrationstests Ausblick: * Spring 2.5 - mehr Annotations; Verwaltung von Entities mit Spring * Webschicht - Anbindung einer Webanwendung mit Java Server Faces (JSF) * Spring-Webservices - Contract-First Webservices mit Spring-WS 1.0

Hire the right way

Selena Deckelmann

Ever hire someone and have it “just not work out”? How long did that take to figure out? Weeks? Days? Before your morning coffee? Hiring, firing and retention are some of the most difficult tasks that a business faces. And we all make mistakes. The tech industry is currently in the middle of a competitive hiring bubble and it’s really hard to find good people. It’s even harder to retain them. So how do you find good people, and keep them? We’ll show what mistakes we’ve made in our combined 30 years in open source and tech.

Postgres has long been a database that easily scales vertically. It has also supported durable and reliable binary replication. In the last two years, work on HA, clustering and extensions to our MVCC system has produced clustering features that help Postgres efficiently scale across many smaller systems. This talk will start with a demo of the latest Postgres replication features. Then, we'll walk through open source and commercially-supported stacks that supporting the most demanding applications backed by Postgres. In version 9.1, Postgres added streaming and synchronous replication that can be configured in about 5 steps. In 9.2 (to be released in 2012), we're adding cascaded replication and optimizations for common developer requests. These features set the stage for a fast, efficient and distributed SQL cluster -- one that has configurable durability, is easy to administer and supported by "cloud" and virtualization vendors.

How to ask for money

Selena Deckelmann

Have a project that just needs some cash to get off the ground? Need someone to fund beer and food for an event? Have a great idea and want to get paid for implementing it? Come find out how we did it. Asking for money doesn’t have to be so hard. Whether you’re working on a non-profit, or a small side project. Or you’re bootstrapping a sweet new developer event. Or you want to find angel investing or venture capital… The same skills apply. Come learn all about how to ask for money from Selena Deckelmann, J Chris Anderson and Teyo Tyree. Selena co-founded Open Source Bridge, raises money for the open source project PostgreSQL and has found funding for many small non- and for-profit projects. J Chris and Teyo both founded VC-backed startups – Couchbase and Puppet Labs – based on open source products. They’ll lead you through their process, their successes and failures. You’ll leave with proven strategies for developing relationships, asking the right questions and providing the right information to people who want to give you their money.

Managing terabytes: When Postgres gets bigSelena Deckelmann

Managing terabytes: When PostgreSQL gets big

Selena Deckelmann

Size can creep up on you. Some day you may wake up to a multi-terabyte Postgres system handling over 3000 tps staring you down. Learn the best ways to manage these systems as they grow, and find out what new features in 9.0 have made life easier for administrators and application developers working with big data. This talk will lead you through solutions to problems Postgres faces when it gets big: backups, transaction wraparound, bloat, huge catalogs and upgrades. You need to monitor the right things, find the gems in DBA-friendly database functions and catalog tables, and know the right places to look to spot problems early. We’ll also go over monitoring best practices and open source tools to get the job done. Working with multiple versions of Postgres back to version 8.2 will be included, and as well as tips on making the most out of new features in 9.0. War stories will be taken from real-world work with Emma, an email marketing company with a few large databases.

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

PHP Frameworks: I want to break free (IPC Berlin 2024)

Ralf Eggert

In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development. This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs

Alex Pruden

This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Elevating Tactical DDD Patterns Through Object Calisthenics

Dorra BARTAGUIZ

After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan 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.

Securing your Kubernetes cluster_ a step-by-step guide to success !

KatiaHIMEUR1

Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster. However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks. In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
