Who discovered grokking and why is the name hard to find?

Fri, 02/13/2026 - 1:05am

Apologies if this is old news to everyone, but perhaps the hive mind knows the answer. I was watching a youtube video "The most complex model we actually understand" by Welch Labs and heard the story about the researcher who left a model training when going on vacation, which then learned to generalize after thousands of training steps. But when I try to look up the name of the discoverer it has not been made public, which seems a shabby way to treat someone. What's the real story?

Show HN: Seedance AShow HN: Seedance AI Video Generation (Next.js, Drizzle)

Fri, 02/13/2026 - 12:57am

Hi HN — I’m an indie maker building Seedance AI. It helps people create short videos (and images) from text prompts and reference photos. I tried to keep it simple: fast templates, predictable credit pricing, and downloadable results. It’s still early, and I know there are rough edges. I’d really appreciate honest feedback on what feels useful, what feels confusing, and what I should improve first. Happy to answer technical or product questions.

A recursive and authoritative DNS resolver from scratch in Go

Fri, 02/13/2026 - 12:43am

I’ve always used 8.8.8.8 or 1.1.1.1, but I realized I didn't actually understand how the resolution chain worked under the hood. To fix that, I built a DNS resolver in Go that performs true iterative resolution from the root servers down, with no upstream dependencies.

Unlike a simple DNS forwarder, this server doesn't just "ask someone else." It implements the full hierarchy: Root → TLD → Authoritative → Final Answer.

Key Technical Challenges I tackled:

Iterative Navigation: Setting RecursionDesired = false so that upstream servers treat the project as a peer resolver.

The "Glue Record" Problem: Implementing sub-resolution where the resolver has to pause the main query to resolve a nameserver's hostname before it can continue.

TTL-Aware Concurrency: Using sync.Map for a thread-safe cache that automatically respects record expiration.

State Management: Handling referrals and avoiding infinite loops in heavily nested zones.

Architecture: The server is built using raw UDP sockets and the dnsmessage package for packet parsing. It handles thousands of concurrent requests using Go’s concurrency primitives.

UDP Listener: Standard net.PacketConn loop.

Resolver Engine: Recursive logic that walks the hierarchy starting from A.ROOT-SERVERS.NET.

Local Overrides: A JSON-based configuration for authoritative local records (useful for dev environments or ad-blocking).

I’d love to hear from anyone who has worked on DNSSEC or handled high-traffic DNS infrastructure. What are the common pitfalls when moving from a "toy" resolver to a production-grade one?
