AppHash

Real-time state non-determinism & consensus monitoring

What it does

apphash.io helps Cosmos SDK chain developers debug app hash mismatches (state non-determinism) by making application state divergence visible. When a mismatch happens, the chain halts, but finding where state diverged usually requires manual RPC diffing and log analysis. apphash.io shows which SDK module produced a different state root and the exact key-value differences inside that module across nodes, turning blind debugging into a concrete, inspectable problem.

    Whirlwind – Async concurrent hashmap for Rust2024 · github.com · ▲140

    Hey HN, this is Will and David from Fortress (https://news.ycombinator.com/item?id=41426998). We use a lot of async Rust internally, and created this library out of a need for an async-aware concurrent hashmap since there weren’t many available in the Rust ecosystem. Whirlwind is a sharded HashMap with a fully asynchronous API. Just as dashmap is a replacement for std::sync::RwLock, whirlwind aims to be a replacement for tokio::sync::RwLock. It has a similar design and performance characteristics to dashmap, but seems to perform better in read-heavy workloads with tokio's…

    Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
