Thoughts and notes
I tried OmniVoice this afternoon because I saw a post on r/LocalLLaMA and got curious. It's a zero-shot voice cloning TTS model that claims 600+ languages. I recorded two short voice memos on my phone, one in Turkish and one in English, dropped them into the web UI, and 30 seconds later voila I had cloned versions of my voice saying things I never said. Each sample took one or two tries to get…
Every year, someone posts a benchmark showing Python is 100x slower than C. The same argument plays out: one side says "benchmarks don't matter, real apps are I/O bound," the other says "just use a real language." Both are wrong. I took two of the most-cited Benchmarks Game problems -- n-body and spectral-norm -- reproduced them on my machine, and ran every optimization tool I could find. Then I…
I built marimo-cython , Cython inside marimo notebooks. A few days later, Vincent Warmerdam (one of my favorite YouTubers, he runs calmcode ) opened a PR to add a "Open in molab" badge. molab is marimo's cloud notebook platform . Then he closed his own PR: Ah wait, nevermind, it seems we don't have gcc on molab containers by default. Right. Cython compiles Python to C, then you need a C compiler…
Last week I benchmarked four web frameworks and found that BlackSheep is 2x faster than FastAPI. A Rust-based server and JSON serializer pushed Python within striking distance of Go. Impressive numbers. But I kept thinking: does any of this matter? Those benchmarks measured localhost throughput with no database and no network. That's not what users experience. A real API request crosses the…
I always felt like JavaScript and Go are the alternative languages for Python. I wouldn't compare Python to Rust or Zig. So when I keep seeing Gin vs Elysia benchmarks, I wanted to throw Python into the mix. FastAPI says it's fast right in the name. Let's find out. Four frameworks, three languages, same Docker constraints, same endpoints. Source code on GitHub TLDR: Python's ecosystem (Granian,…
