Backpressure: a system’s way of saying “slow down” before overload turns into timeouts and retries. Understand why it matters and what signals it uses.

Load shedding rejects work during overload so systems stay usable. Learn why it matters, what it looks like, and how it prevents retry storms.

Software debugging fundamentals for developers: mental models, evidence-driven workflows, observability signals, and practical techniques for finding root causes fast.

Networking fundamentals for developers: packets, IP addressing, routing, TCP and UDP, DNS, TLS, and a practical troubleshooting mental model.

Why learn software fundamentals? They outlast frameworks and reduce pain. Build skills that pay off for your career and your users.

Algorithmic patterns reference: two pointers, sliding window, dynamic programming, and 30+ more. Learn to spot patterns and solve problems faster.

Algorithmic patterns explained: why patterns work, how patterns combine, and how to practice recognition without memorizing solutions.

CPU vs GPU vs TPU: learn how processing architectures differ, when to use each, and how latency, throughput, and data movement shape performance.

Data structures guide: arrays, hash maps, sets, stacks, queues, trees, graphs. Types, properties, when to use in Python, JavaScript, Java, C++, Go, Rust.

Master data structure fundamentals: arrays, hash maps, trees, and graphs. Learn how structure choices shape algorithm performance, reliability, and developer sanity.
