A preview of the 15-track QCon London 2027 program, covering agent evaluation and guardrails, AI-era architecture, distributed-system debugging, modern data platforms, high-performance engineering, and Staff+ leadership. By Artenisa Chatziou
Matthew Liste explains the 12 core principles of building scalable, reliable platforms for enterprise tech teams. From avoiding technical debt and managing deprecation to building a strong engineering culture, Liste discusses how to design infrastructure platforms that reduce complexity, streamline developer workflows, and deliver long-term value for senior architects and engineering leaders.

Przemyslaw Alexander Kaminski created RACE, a Rust terminal multiplexer on an infinite canvas that detaches child shells into background processes. When he launched an ad campaign, automated scanners suspended his account for malware despite clean notarization and Safe Browsing checks. The flag illustrates operational deadlocks when ad heuristics evaluate POSIX process architectures. By Olimpiu Pop
Cloudflare recently launched the open beta of cf, a new open-source, agent-focused command-line interface for interacting with Cloudflare services through a unified CLI. Written in TypeScript, it provides structured output and command discovery to make Cloudflare’s APIs easier for both developers and AI agents. By Renato Losio
This week's Java roundup for September 28th, 2026, features news highlighting: the GA releases of JobRunr 9.0 and OpenXava 8.0; point releases for Quarkus, Micronaut, LangChain4j, Eclipse JNoSQL; ADK for Java and ADK for Kotlin; and introducing Lathe, a new Java language server. By Michael Redlich
Akka used 65 open-source projects to examine how specification structure, context, model selection, automated validation, and delivery guardrails affect AI assisted software porting. The experiment measured time, token use, code size, test parity, and performance, finding substantial variation across models, effort levels, and project types. By Leela Kumili
Susan Chang explains how Elastic transitioned from siloed, ad-hoc AI agent evaluations to a unified, production-grade framework. She discusses balancing LLM-as-a-judge with deterministic rules, bridging Python data science evals with TypeScript production code, and implementing deep tracing to catch regressions across complex RAG and cybersecurity workloads while preserving domain context. By Susan Chang
In this article, author discusses his experience with AI agent hallucinations in an inventory recommendation system and how this problem was solved by treating the LLM stack as a platform infrastructure concern instead of as an application one. He makes a case for a shared LLM platform with common services like prompt registry & versioning, schema enforcement and token cost attribution by request. By Aditya Mulik
In this episode, Chris Swan, engineer at Atsign and security track host at QCon London, reflects on the ideas shared during QCon London 2026 and teases topics of the future edition. The discussion explores how security engineering is shifting from relying on human vigilance toward automated, system-level defences across the entire application stack. By Chris Swan
Microsoft has released Aspire 13.6. The dashboard now stores telemetry in SQLite and keeps up to ten completed runs per application. The release adds prerelease hosting packages for Java and Rust, portable volume paths, and new CLI options. Breaking changes include automatic TLS for local MongoDB resources and a new default Cosmos DB emulator image. By Almir Vuk
Cloudflare has disclosed a cross-tenant data exposure vulnerability in Containers and Sandboxes, caused by thin-provisioned storage pools configured to skip zeroing reused blocks. Researchers recovered directory structures, database pages and complete SQLite databases across four continents. Cloudflare remediated it and found no evidence of exploitation. By Steef-Jan Wiggers
