Learn Your Way: Reimagining Textbooks with Generative AI

Grounded in learning, built for the student Our approach is built on two key pillars that work together to augment the learning experience: (1) generating various multimodal representations of the content, and (2) taking foundational steps toward personalization. The seminal dual coding theory states that forging mental connections between different representations strengthens the underlying conceptual schema in our brain. Subsequent research indeed showed that when students actively engage wi

Ask HN: Generalists, when do you say "I know enough" about any particular topic?

The idea is generalists know a lot about everything and when to pass it off to a subject matter expert. In 2025, with everything in tech changing by the minute, I’m realizing I need to set boundaries about how deep I go on any particular topic. But I’m unsure how. Particularly if I don’t want to get left behind as things continue to evolve. Curious how other folks approach this?

Turning Claude Code into my best design partner

Published on August 18, 2025 When I first started using Claude Code, I had a naive approach to working with it. I would describe the task directly in the prompt, press Enter, and cross my fingers. If the agent made mistakes, I would tell it how to fix them. For small tasks, this can be good enough, but as the task grows in complexity, this approach reveals several significant drawbacks. When Simple Doesn’t Scale The first problem is that the conversation becomes the only source of truth about

Lessons learned from building a sync-engine and reactivity system with SQLite

Over the last couple of months, I've been trying to build the dream: A local-first, end-to-end encrypted and reactive app, with all of the user's data in a local SQL database but continually synced to a remote server. This article summarizes my learning and how I ended up building a minimal sync engine for SQLite with full reactivity. First Try: PGlite and Electric My first try was with Electric and a WASM-based version of PostgreSQL called PGlite that can run directly in the browser. I ev

Analyzing Control Flow More Like a Human [video]

Time and Location Date: Wednesday, August 6 Wednesday, August 6 Time: 1:00-2:00PM 1:00-2:00PM Location: Luddy Hall 1104 Abstract Control-flow analysis has been around for over four decades. Over this time period, the typical formulation has remained essentially an exhaustive analysis over whole programs—an analyzer ingests an entire higher-order program and produces a flow fact for each point therein. An alternative approach is demand-driven. Implementing this approach, an analyzer allows t

VTuber agency VShojo shuts down after talent exodus

VShojo has failed and I’ve mismanaged the company into the situation you’re all witnessing. So today I am sharing the difficult news that VShojo is shutting down, and I take full responsibility for the decisions that led us to this point.

Over the past few years, we raised around $11 million to pursue a bol

The fall of 1987. Hawkins is scarred by the opening of the Rifts, and our heroes are united by a single goal: find and kill Vecna. But he has vanished — his whereabouts and plans unknown. Complicating their mission, the government has placed the town under military quarantine and intensified its hunt for Eleven, forcing her back into hiding. As the anniversary of Will’s disappearance approaches, so does a heavy, familiar dread. The final battle is looming — and with it, a darkness more powerful
