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...

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 critic...

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 accu...

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 Zarvo...

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 w...

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...

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 inconsistenc...
