Identifying and fixing Issues in Code using AI based tools
SPEAKER: Venkat Subramaniam COMPANY: Agile Developer, Inc.
KEYWORDS: AI, Security, Tools
Software vulnerability is a huge concern. What's lurking in code is a question that keeps passionate programmers up at night. Is there a memory leak, what about a race condition, oh what about security issues, are we violating purity of functions when we're not supposed to? We have to maintain code that others have written and it's not always easy and quick to detect those defects ticking away in the code.

Softwarearchitektur in Eigenregie bewerten
Mit LASR in 2-3 Stunden zu ersten Review-Ergebnissen
SPEAKER: Stefan Zörner COMPANY: embarc Software Consulting GmbH
KEYWORDS: Architecture
Mit Architekturbewertungen ist es möglich, Schwächen und Potenziale von Softwarelösungen herauszuarbeiten, Entscheidungen abzusichern und Verbesserungsmaßnahmen zu bewerten. Klassische Analyseansätze aus diesem Umfeld wie ATAM sind fundiert, kommen aber gerade in beweglichen Softwarevorhaben etwas schwergewichtig, mitunter fast zeremoniell daher.

Deterministische Tests für nicht-deterministischen Code
Multithreading in Java beherrschbar machen
SPEAKER: Thomas Krieger
KEYWORDS: Methods, Open Source, Testing, Tools
Multi-Threaded Java verhält sich per Definition nicht deterministisch. Genau das macht das Testen so schwierig. Klassische Unit-Tests reichen oft nicht aus, um Race Conditions oder Deadlocks zuverlässig zu finden.

GraalVM Summit Warm-up with JUG Switzerland
SPEAKER 1: Graeme Rocher COMPANY: Oracle
SPEAKER 2: Thomas Wuerthinger COMPANY: Oracle
SPEAKER 3: Florian Enner COMPANY: HEBI Robotics
KEYWORDS: Lessons learned, Open Source, other Languages, Technology
The GraalVM Community Summit is coming to Zurich on October 21-22, bringing together contributors, partners, and users from across the community. The evening before, JUG Switzerland will welcome three speakers from the GraalVM community for a special meetup.
And with many community members already in Zurich for the Summit, there may be a few more familiar faces around too. Definitely one you do not want to miss.

Kill your Tests
Wie wir den E2E-Sumpf mit KI-Agenten endlich trockenlegen
SPEAKER: Felix Tensing COMPANY: NÜRNBERGER Versicherungsgruppe
KEYWORDS: AI, Lessons learned, Testing, Tools
Wir kennen es: Die E2E-Testsuite wächst schneller als der eigentliche Feature-Code. Was als gute Absicht begann, endet in einer unübersichtlichen Sammlung von Copy-Paste-Wüsten, die ewig laufen und am Ende doch nur Zufallsergebnisse in einer chronisch roten Pipeline liefern.

Beyond Hype
An Engineering Approach to Evaluating Coding Assistants
SPEAKER: Robert Munteanu COMPANY: Adobe
KEYWORDS: AI, Tools
AI coding assistants are quickly becoming part of everyday development workflows, and teams are starting to invest in agent-specific tooling such as reusable skills, repository instructions, and external tool integrations. But before adopting or expanding that tooling, we should ask a basic engineering question: does it actually improve results? A higher task success rate is useful, but it is not enough on its own. Speed, cost, and reliability matter too.

Raft by Hand: What Lies Between the Paper and a Production Cluster
From Consensus Algorithm to a Reliable System in Production
SPEAKER: Felix Berger COMPANY: fbt Berger – Future Build Technology Berger
KEYWORDS: Architecture, Open Source, Tools
Anyone running Kubernetes, Kafka or Consul depends on a consensus algorithm every single day – most likely without ever having seen one. It is the reason a cluster can still agree on one shared truth when individual nodes fail or the network splits apart. And it is the reason two nodes must never both believe they are in charge.
Raft is considered one of the more approachable consensus algorithms. Leader election and log replication fit into a few pages of the paper. Between an understandable algorithm and a cluster you would trust with production data, however, lie a number of surprisingly hard details.
