❯ ./tatkal-rush
Your turn: run the front door.
10:00 IST. Two million people and a few hundred thousand bots want 500 train seats. Every 10 seconds you read the door telemetry, set how fast the waiting room admits people, and pick one bot shield. Seats go out through one atomic counter, so nothing sells twice; the question is who gets them.
- score · +1 per seat to a traveller, −2 per seat to a bot, −2 per traveller wrongly blocked, −½ per 503, −40 per phase over 800 ms p99, −150 per meltdown, +6 per second sold out early
- win · 340+ points and the database never melts. Every morning is different.

- CASE-012.mdoct 2026 · 18 minThe $440M Deploy: Knight Capital's 45 MinutesOne server out of eight missed a deploy. A recycled feature flag woke up code retired nine years earlier, and in 45 minutes a Wall Street trading firm lost about $440 million. This is how it happened.
- CASE-013.mdoct 2026 · 19 min25.3 Million People, One Cricket Match: Why Hotstar Scaled Before the Star Walked InJuly 2019. India are 5 for 3, Dhoni walks in, and a million new viewers arrive every minute. How Hotstar served a world-record 25.3 million at once by scaling before the moment, not after it.
- CASE-011.mdoct 2026 · 19 minOne File, 8.5 Million Blue ScreensOn July 19, 2024, a routine security content update reached Windows machines worldwide in 78 minutes and crashed about 8.5 million of them. The cause: a rule that asked for field 21 when the sensor only had 20.
