Big ideas,
served in small bites.
Tidbit turns dense, intimidating tech into friendly visual guides you can actually digest: system design, databases, AI, and more.
The guides
Pick a shelf and start nibbling.Core concepts behind building scalable, reliable distributed systems. Covers the patterns and trade-offs every backend engineer needs to know.
The classic Gang of Four patterns visualised with UML diagrams and annotated code. Creational, structural, and behavioural patterns in one place.
A deep dive into how PostgreSQL actually works under the hood: storage, indexing, MVCC, transactions, and the WAL explained with diagrams.
Production-grade cloud patterns for event-driven systems, serverless, resilience, data management, and deployment strategies.
From neurons to transformers. Everything you need to understand how large language models are built, trained, and deployed.
The hard engineering problems behind shipping reliable AI agents: memory, concurrency, retries, observability, and failure handling in production.
Foundational CS: arrays, linked lists, trees, graphs, sorting, searching, and complexity analysis. The algorithms every engineer needs to know.
How the internet works: TCP/IP, DNS, HTTP/2, QUIC, routing, packet switching, and the protocols that move data across the globe.
Threads, goroutines, async/await, green threads, locks, deadlocks, and the patterns for building systems that do multiple things at once safely.
Docker, container orchestration, deployments, service discovery, networking, and production container platforms at scale.
SSL/TLS, encryption, hashing, authentication, authorization, common vulnerabilities, and the cryptography you need to build secure systems.
