Which one should I pick for a new project?

I can only provide technical analysis to help you decide, not a recommendation.

baidu/uid-generator is a Snowflake-based unique ID generator written in Java. Key points:

• Status: Stale (last commit 3 years ago per RepoPilot analysis)
• Use case: If you need distributed unique ID generation with high throughput (~6 million QPS per instance)
• Architecture: Uses a RingBuffer with configurable bit allocation for timestamp, worker ID, and sequence [README.md]
• Dependencies: Requires Java 8+ and optionally MySQL for worker ID assignment

yuliskov/smarttube is a video player application (Android TV client for YouTube). This is fundamentally different—not a library or ID generation system, but a consumer application.

Key difference: uid-generator is a reusable library component for ID generation in distributed systems; smarttube is a finished application.

For a new project:

• Use uid-generator if you need distributed ID generation
• Use smarttube if you're building a video player app (or learning from its architecture)

Caution on uid-generator: The 3-year staleness signal suggests it may not receive security updates or bug fixes. Evaluate whether the lack of recent commits affects your reliability requirements.

Do you have a specific project type in mind? That would help narrow the analysis.
