Predictive modeling is a core element in modern systems, and powers capabilities such as fraud detection, loan approvals, and recommendation systems. These systems typically operate on structured, relational data stored in enterprise databases, with rows, columns, and interlinked tables. While computer vision and natural language processing have undergone a neural network revolution, the tabular data layer underpinning predictive modeling still largely relies on manual feature engineering and task-specific models.

Relational deep learning proposes a new approach. It treats databases as graphs and applies transformer-style attention mechanisms directly over structured relational data. Researchers are now building foundation models...

Modern web development requires an ever-growing collection of tools including formatters, linters, bundlers, and plugins. Each tool typically has its own configuration, dependencies, and performance cost. As applications grow more complex, the overhead of maintaining this toolchain becomes a real burden.

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 credible alternatives for production workloads, with advantages in customization and data privacy.

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 operations. Today they are working to apply AI to move observability beyond passive monitoring toward active intelligence, where systems can surface what matters, reduce alert noise, and ultimately...

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 to grow. Guardsquare builds tools to protect and test mobile applications against both static and dynamic threats. Its platform has features including layered code...

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 most organizations.

The Extended Berkeley Packet Filter, or eBPF, is a Linux kernel technology that allows sandboxed programs to run safely inside the kernel without modifying...

Bennett Foddy is a legendary game designer known for creating wholly distinctive games such as QWOP, Getting Over It with Bennett Foddy, and the recently released Baby Steps. He’s also a former professor at the NYU Game Center, where he taught game design alongside developing his own experimental work.

In this episode, Bennett joins Joe Nash to discuss his systems-driven approach to game design, why frustration and difficulty are often misunderstood, how streaming and speedrunning have reshaped how games are played and experienced, and what makes his games stand out.

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 spending too much time debating code style instead of building software. It offers a deterministic, opinionated formatter that helped normalize au...

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 recreate entire environments, limiting interactivity and slowing feedback.

Marimo is an open-source, next-generation Python notebook designed to address these problems directly. Akshay Agrawal is the creator of...

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.

Unblocked is a startup focused on solving this context gap. Their context engine aggregates and reasons...
