An Inside Look at the Components of a Recommendation Engine
Posted on April 13, 2015 at 9:14am 1 Comment 0 Likes
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,…

QCon London 2026: Use<’lifetimes> For<’what>
At QCon London, TrueLayer engineer Ethan Brierley reframed Rust lifetimes using the Polonius borrow checker's mental model: lifetimes as sets of loans rather than regions of code. He built from borrow checker basics through variance and subtyping to higher-ranked lifetimes with serde, showing how the loans perspective makes previously confusing lifetime errors intuitive.
By Steef-Jan WiggersQCon London 2026: Blurring the Lines: Engineering & Data Teams in the Age of AI
At QCon London 2026, Lada Indra, Head of Data Platform at Pleo, shared insights from his experience across high-scale data systems. He illustrated both the risks of poorly aligned teams and the practical strategies that organizations can adopt to bridge the gap.
By Daniel DominguezArticle: Beyond Memory Safety: What Makes Rust Different – Lessons from Autonomous Robotics
This article explores that question through the lens of a real-world Rust project: a system responsible for controlling fleets of autonomous mobile robots. While Rust's memory safety is a strong foundation, its true power lies in the type system and ownership rules. The session will go beyond memory safety and explore ways to encode behavior and protocols directly into types.

Earlier this month, Iranian drone strikes damaged three AWS data centers in the UAE and Bahrain, causing outages and disruptions to multiple services. The events, which affected multiple facilities within the same AWS region, sparked discussion in the community about how geopolitical conflict can directly impact global cloud infrastructure and multi-AZ deployments.
By Renato LosioQCon London 2026: Uncorking Queueing Bottlenecks with OpenTelemetry
At QCon London 2026, Julian Wreford and Oli Lane from Gearset showcased how distributed tracing and SLOs solve asynchronous observability gaps. By shifting from queue-size metrics to latency-based alerts, the team improved incident response. Key technical takeaways included using OpenTelemetry trace state for async duration tracking and wide events to uncover hidden architectural waste.
