# grmchn/dopa-drill > Browser-based arithmetic drill where visuals and music escalate with each solved problem, with grade-based and adaptive self-level modes. - Magnitude: 5.4 out of 10 — Early signal - Stars: 128 total · +94 stars today, ≈ 126 by evening - Star trust: star growth looks organic - Category: Learning & lists · Language: JavaScript · Created: 2026-09-27 · Last push: 2026-09-28 - GitHub: https://github.com/grmchn/dopa-drill · Page: https://gitnova.dev/en/r/grmchn/dopa-drill ## Useful for - Run a local server and practice arithmetic following the grades 1–6 curriculum - Assess a child's skills via the self-level mode and track progress on the skill tree - Run node --test to verify the scoring logic ## Why it’s here - 94 stars so far today, about 126 expected by the end of the day. - The spike has held for 3 days in a row — not a one-off blip. - The repository is 2 days old and already has 128 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet. - Top new repositories this week: #113. - About 84 forks a day — people are taking the code. ## Star trust Star growth looks organic. Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer. ## Numbers - Forks: 42 - Issues and pull requests: 1 - Watchers: 0 - Average over the last week: 53 per day - Usual pace: too little history (under two weeks) - Stars in the last hour (measured): 10 ## Stars per day, last 10 days (oldest → newest, today is partial) 2026-09-20 … 2026-09-29: 0, 0, 0, 0, 0, 0, 0, 12, 22, 94 ## Spotted in now - Top new repositories this week: #113 ## More in this category 1. **cdyforever/how-to-live-better** — 7.1 · Breakout · Learning & lists · HTML · +517 stars today, ≈ 820 by evening A single-file HTML reading page for the open book "High Cost-Performance Life Guide" — 528 tips across 32 sections, searchable, offline-capable, zero dependencies.

Full card: https://gitnova.dev/en/r/santtiago49/system-design-trainer.md --- 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.
