Recommendation engines help narrow your choices to those that best meet your particular needs. In this post, we’re going to take a closer look at how all the different components of a recommendation engine work together. We’re going to use collaborative filtering on movie ratings data to recommend movies. The key components are a collaborative filtering algorithm in Apache Mahout to build and train a machine learning model,…

During QCon SF, Jeremy Edberg and Qian Li from DBOS presented a non-conventional architectural approach to workflow orchestration: treating PostgreSQL not just as a data store, but as the orchestration layer itself. Their talk addressed a persistent problem in distributed systems: workflows frequently fail, recovery mechanisms are complex, and visibility into workflow state remains challenging.

AI-generated code is “highly functional but systematically lacking in architectural judgment”, a new report from Ox Security has found. In a report released in late October called Army of Juniors: The AI Code Security Crisis, AI application security (AppSec) company Ox Security outlined 10 architecture and security anti-patterns that are commonly found in AI-generated code.

At QCon SF 2025, Dr. Nicole Forsgren highlighted how AI accelerates code generation but reveals deployment bottlenecks, urging a strategic pivot to optimizing Developer Experience (DevEx). With 31% of developer time lost to friction, focusing on effective feedback loops, flow state, and cognitive load management is vital for competitive survival and retention.

IBM recently announced the Granite 4.0 family of small language models. The model family aims to deliver faster speeds and significantly lower operational costs at acceptable accuracy vs. larger models. Granite 4.0 features a new hybrid Mamba/transformer architecture that largely reduces memory requirements, enabling Granite to run on significantly cheaper GPUs and at significantly reduced costs.
