[Other] Show HN: TokenDagger – A tokenizer faster than OpenAI's Tiktoken TokenDagger is a drop-in replacement for OpenAI’s Tiktoken (the tokenizer behind Llama 3, Mistral, GPT-3.*, etc.). It’s written in C++ 17 with thin Python bindings, keeps the exact same BPE vocab&#x2F;special-token rules, and focuses on raw speed.<p>I’m teaching myself LLM internals by re-implementing the stack from first principles. Profiling TikToken’s Python&#x2F;Rust implementation showed a lot of time was spent doing regex matching. Most of my perf gains come from a) using a faster jit-compiled regex engine; and b) simplifying the algorithm to forego regex matching special tokens at all.<p>Benchmarking code is included. Notable results show: - 4x faster code sample tokenization on a single thread. - 2-3x higher throughput when tested on a 1GB natural language text file.

[Other] Show HN: I rewrote my notepad calculator as a local-first app with CRDT syncing I launched NumPad v1 on here a few years ago, and back then it wasn&#x27;t much more than a thin CodeMirror wrapper around the calculator engine I&#x27;d written.<p>Now I&#x27;ve rewritten it as a PWA that supports multiple documents, persists them to IndexedDB, and has a syncing service for paying customers. Syncing is handled by Automerge[1] under the hood, which <i>should</i> make it relatively easy to get document sharing working too.<p>[1] <a href="https:&#x2F;&#x2F;automerge.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;automerge.org&#x2F;</a>
