- Build Python from source with --enable-optimizations and --with-lto
- Run make test to verify the interpreter after changes
- Build a debug interpreter via configure --with-pydebug

## Why it’s here

- Star-counter measurements on 2026-10-14 (UTC), 10:58–11:51: 77747 → 77750 stars (+3). This is the change over that interval.
- Estimated end-of-day forecast: about +34 stars, using observed gains and the previous day.
- Over the last two days the pace is 2.7× that of the previous week and a half.
- GitHub Trending Python today: #7, +127 stars.
- Hacker News: “Python 3.15” — 316 points, 4 days ago.
- About 280 forks a day — people are taking the code.

## Star trust

Unusual star pattern (heuristic).
- Stars arrived in one batch on a single day (412) and stopped right after: 30 over the next two days. Real interest usually fades gradually.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 38,340
- Issues and pull requests: 157,036
- Watchers: 1,670
- Average over the last week: 36 per day
- Usual pace: 36 per day
- Stars in the last hour (measured): 9

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
