Scalac's blog

Four Claude Code agents review a pull request, a fifth checks every finding against the code, and a person gets a short note with the lines to read first. Five lessons from a real PR, plus what the setup costs compared with ready-made tools.

This month the damage came through tools people trust: a certificate authority's guessable keys that a default JVM kept trusting, an exchange drained through its own wallet signing service, and AI reviewers that find bugs faster than maintainers can fix them. Plus Kafka 4.4's new startup checks, Scala 3.10 and GitHub rebuilding Git for agents.

November is bringing plenty of opportunities to learn something new, meet fellow builders, and explore how AI is changing the way we write software. From smarter AI systems to the engineering practices that keep them reliable, there’s a lot to unpack, and, naturally, a few events worth adding to your calendar. This month’s Scalendar mixes […]

Five failures went through the mechanism built to prevent them: agents that could only read the web, a database failover with no fencing, a flight-data link that reconnected on its own and a Kafka broker that lost data on a clean shutdown. Plus decision models on the JVM, Scala 3.9 LTS and JDK 27.

October is shaping up to be a busy month for the Scala and functional programming communities, with plenty of opportunities to learn, connect, and exchange ideas. From Scala Days in Berlin to functional programming events in Stockholm and Málaga, this month brings together developers working on the technologies shaping modern software development. AI is also […]

Databricks puts a source-first index in Metals v2, while Netflix shows why a materialised service map may prefer complete data to fresh data. Plus Gradle Isolated Projects, Intel Mac support, JDK PEM encodings and durable agents.

EU instant payments settle in seconds, but AI-driven payment decisions must remain explainable for years. Here’s how to design agents for speed, control, and long-term auditability.

September is here! September 2026 is bringing plenty of exciting opportunities for the Scala, AI and JVM communities. From large international AI conferences to developer-focused events, there is something for everyone interested in technology and software development. This month’s Scalendar highlights some of the most interesting events happening around the world, including where they are […]

An agent walked ten open doors from template injection to cluster-admin inside Hugging Face production. Every one of those doors is open in a normal JVM shop.

Welcome to the August 2026 edition of Scalendar — your monthly roundup of Scala events, conferences, meetups, and community happenings from around the world. While August is typically a quieter month for Scala-exclusive conferences, it’s still packed with opportunities to connect with the wider JVM, functional programming, data engineering, and AI communities. From open-source summits […]
