Q & A

What is the primary focus of Lee Chess as a platform?

The primary focus of Lee Chess is simplicity, user experience (UX), and scalability. It aims to offer a minimalist interface, prioritize backend logic, and make use of efficient, robust technologies to provide a seamless chess-playing experience.

What unique approach does Tibo Dupleix (TBO) take in managing technical debt?

Tibo Dupleix focuses on fixing technical debt early and consistently, ensuring that legacy systems or services are not neglected. He believes in preventing tech debt from slowing down development, and approaches it as an ongoing task rather than something to be dealt with only in crises.

Why does TBO advocate for a minimalist frontend approach?

Tibo advocates for a minimalist frontend because he believes in keeping the user interface (UI) simple while moving as much logic as possible to the backend. This helps avoid performance bottlenecks and keeps the user experience clean and focused on functionality.

What technologies are used in the Lee Chess platform and why?

Lee Chess utilizes Scala for its strong type system and scalability, MongoDB for flexible data handling, Redis for real-time data management, and Rust for high-performance microservices. These technologies are chosen for their reliability, scalability, and ability to handle large-scale systems efficiently.

How does Lee Chess handle scalability and performance?

Lee Chess is designed to scale by utilizing a monolithic architecture with 'satellite' services. This combination allows for a high-performance core while maintaining independent services for specific tasks like web sockets and analysis, which ensures flexibility and minimizes system load.

What role does open-source play in Lee Chess's development?

Lee Chess is fully open-source, allowing the community to contribute and collaborate. Tibo Dupleix values the open-source model as it fosters transparency, collaboration, and ensures that the platform remains focused on community-driven development, rather than commercial interests.

Why does Tibo believe that UX is more important than UI?

Tibo believes UX is more important than UI because the core focus should be on functionality, ease of use, and providing a seamless user experience. The interface should be minimalistic and not distract from the platform's primary purpose—playing chess.

What is Tibo’s mindset towards mistakes in software development?

Tibo embraces the idea that mistakes will happen, acknowledging that no one writes perfect code. His mindset is to focus on fixing yesterday's bugs while constantly creating new bugs or features for tomorrow, which keeps the development cycle dynamic and adaptable.

How does Tibo approach feature development in Lee Chess?

Tibo is deliberate about which features to include in Lee Chess. He ensures that any new feature has a logical place in the user interface (UI) and aligns with the platform's overall mission. He avoids adding unnecessary features that would complicate the platform.

What does Tibo mean by 'using the right tool for the right job'?

Tibo emphasizes that developers should choose technologies based on the specific needs of the project. He values using functional programming languages like Scala for large, complex codebases and low-level languages like Rust for performance-critical tasks, avoiding overcomplication by sticking to proven tools.
