๐ Check out this must-read post from Hacker News ๐ ๐ **Category**: ๐ **What Youโll Learn**: A visualization tool that replays coding-agent sessions on a 3D map of your codebase. A session log records what an agent did, but not how it understood the task: which parts of the repo it treated as relevant, where it explored before it acted, whether its footprint matched the scope you had in mind. Reading the raw JSONL line by line doesn't answer any of that. Draw the repository as a night map, and play the session back as light moving through it: where…

This month, the U.S. Department of Education began rolling out a new accountability test that most colleges and universities will soon have to pass. The test itself is simple: If an undergraduate program's graduates don't earn more than workers who never went to college, that program could be cut off from federal student loans. The same goes for any graduate program whose graduates earn less than someone with only a bachelor's degree. "If…

Using a method called extensional rheology, Lima stretches liquids between metal plates to find the force that makes them flow. A few years ago, she was conducting a test as part of a project in collaboration with the oil and gas company Exxon Mobil when she heard a short,…

**What Youโll Learn**: Itโs our job to build the software factory - not just the software. Software engineers maintain the assembly line allowing anyone to prompt for a change and ship immediately. We set up the infrastructure that makes agents successful. We act proactively through prompts (skills, AGENTS.md, knowledge bases etc). We protect software reactively through automated evaluation (tests, linting, type systems, evals, other AI, etc). It all keeps the agent on track. Even a stupid model, with fresh context, can work within these constraints and produce a…

**What Youโll Learn**: American consumers are angry. Nearly 80% of Americans had a service or product problem in 2025, and about two-thirds of those felt โrageโ about it, according to the โNational Consumer Rageโ survey.Many consumers feel they are constantly fighting against an onslaught of overcharges, customer service hassles, shoddy products and billing mistakes that always seem to go in the companyโs favor. All of this comes against a background of soaring prices and rising inflation.Thereโs a stew of factors at work behind the rise in consumer rage:…

**What Youโll Learn**: A production-grade, deterministically bounded-jitter, fault-tolerant infrastructure engineered for real-time Quantum Error Correction (QEC) and autonomous topological stabilization in multi-sector superconducting qubit grids. It leverages a 3-Tier Hardware-Fused Control Loop to bypass classical decoding bottlenecks, executing zero-overhead, branchless syndrome mitigation at the hardware edge. ๐ Technical Background: Demolishing the Decoding Latency Wall Traditional Fault-Tolerant Quantum Computing (FTQC) infrastructures face a catastrophic decoding latency wall: scaling the physical qubit footprint injects severe, computationally heavy centralized decoding overhead (such as Minimum-Weight Perfect Matching or union-find routines). This…

Years ago, Charlie, a highly respected orthopaedist and a mentor of mine, found a lump in his stomach. He had a surgeon explore the area, and the diagnosis was pancreatic cancer. This surgeon was one of the best in the country. He had even invented a new procedure for this exact cancer…

Racks of GPUs that belong to someone else, a metered API, and a bill that grows every month you succeed. You send your prompts off to a black box and hope the price, the model, and the privacy policy all stay the way they were when you signed up. For a lot of teams that is a bad trade. You give up control over when models change, where your data goes, and…
