Open source software underpins nearly every modern application, including frameworks powering the most popular websites, to the libraries securing financial backend systems. However, while open source drives collaboration and innovation at a global scale, it also faces deep challenges in sustainability, community health, and long-term maintenance. Many of the world’s most critical dependencies are still maintained by just a handful of volunteers. Abby Cabunoc Mayes leads Open Source Maintainer P...

Vector search has risen to become a foundational tool in modern search and retrieval systems, including the RAG pipelines that power many AI applications. However, the demands on retrieval systems are growing more sophisticated, which is revealing the limits of relying on a single vector similarity score. Vespa is a popular open source search and data serving engine. Central to Vespa’s architecture is tensor-based retrieval, which is an approach that represents data as tensors rather than simple...

Artificial intelligence is transforming warfare faster than the legal and ethical frameworks designed to govern it. Militaries around the world are deploying AI-powered decision support systems to identify targets, assess proportionality, and direct weapons. The gap between what is technically possible and what international law can effectively regulate is widening by the day. Yuval Shany is a law professor at Hebrew University of Jerusalem and a research fellow at the Oxford Ethics in AI Instit...

Open-weight models are AI systems whose trained parameters are publicly released, which allows developers to run, fine-tune, and deploy them independently rather than accessing them only through a hosted API. While closed-weight models from companies like OpenAI or Anthropic are delivered as managed services, open-weight models give organizations direct control over how the models are deployed and used. Importantly, the performance of these models is steadily improving and they’ve become credibl...

AI agents are increasingly capable of reasoning and performing autonomous work over long periods. However, as agents take on more complex, longer-horizon tasks, keeping them supplied with the right information becomes the core engineering challenge. The industry is moving away from pre-loading context upfront toward a model where agents dynamically navigate and retrieve the data they need, when they need it. Redis is approaching context management using a context engine, which is an architecture...

AI agents are evolving from individual productivity tools into distributed systems components inside enterprises. The next frontier is coming into focus, and it involves large-scale ecosystems of collaborating agents embedded directly into business processes. However, multi-agent architectures introduce serious challenges around orchestration, state management, trust, governance, and observability. Eric Broda is a veteran of the software industry, and he’s the co-author of the new O’Reilly book,...

Observability emerged from the need to understand complex software systems, and involves tracking metrics, logs, and traces so engineers can detect and diagnose problems before they affect users. However, modern applications often encompass hundreds of services, containers, and dependencies, generating more observability data than dashboards and alerts alone can effectively surface. New Relic is a leading observability platform, with a history that spans the full arc of modern software operation...

Mobile apps have become a primary interface for critical services, including banking, payments, and healthcare. Unlike web applications, much of the logic and intellectual property in a mobile app lives directly on the user’s device, which is an environment the developer doesn’t control. That makes mobile apps uniquely exposed to reverse engineering, runtime manipulation, and fraud. As more critical functionality shifts to mobile, the need to harden apps against sophisticated attackers continues...

Modern cloud-native systems are built on highly dynamic, distributed infrastructure where containers spin up and down constantly, services communicate across clusters, and traditional networking assumptions break down. Linux networking was designed decades ago around static IPs and linear rule processing, which makes it increasingly difficult to achieve scale in Kubernetes environments. At the same time, modifying the Linux kernel to keep up with these demands is slow, risky, and impractical for...

Developer tooling shapes how software gets written day to day, but the best tools often disappear into the background once they succeed. Formatting, linting, and build systems can either create friction and endless debate, or quietly remove entire classes of problems from a team’s workflow. Over the past decade, the JavaScript ecosystem has wrestled with both extremes as it scaled rapidly and accumulated complexity. Prettier emerged as a response to the surprisingly human problem of engineers sp...

Skateboarding games have long balanced technical precision with a sense of flow and expression, but Skate Story takes the genre in a radically different direction. It has a distinct vaporwave vibe and blends fluid skate mechanics with exploration, puzzles, and an existential narrative about freedom, pain, and obsession. The game was created by indie developer Sam Eng , who previously released Zarvot for the Nintendo Switch. Skate Story launched to critical acclaim and was widely regarded as one ...

Retrieval-augmented generation, or RAG, has become a foundational approach to building production AI systems. However, deploying RAG in practice can be complex and costly. Developers typically have to manage vector databases, chunking strategies, embedding models, and indexing infrastructure. Designing effective RAG systems is also a moving target, as techniques and best practices evolve in step with rapidly advancing language models. Google DeepMind recently released the File Search Tool, a ful...

Interactive notebooks were popularized by the Jupyter project and have since become a core tool for data science, research, and data exploration. However, traditional, imperative notebooks often break down as projects grow more complex. Hidden state, non-reproducible execution, poor version control ergonomics, and difficulty reusing notebook code in real software systems make it hard to move from exploration to production. At the same time, sharing results often requires collaborators to recreat...

AI agents have taken on a growing share of software development work, so much so that the hardest problems are shifting away from code generation towards something new, context. The challenge is now contextualizing why systems work the way they do, how architectural decisions were made, and the sources of truth that exist outside of the code base. As teams adopt agentic tools, gaps or inconsistencies in context have emerged as a primary reason why software fails to meet production standards. Unb...
