APIs and HTTP for FDEs
YOU NOW KNOW ENOUGH WHENYou can trace a request, explain status codes, retries, timeouts, and idempotency.
PRIMERS
Learn enough foundation to enter the real problem.
These are bridges, not compressed computer-science degrees. Each primer defines the threshold you need, then points to an authoritative deep resource.
Authoritative resource ↗
Database state and transactions
YOU NOW KNOW ENOUGH WHENYou can separate durable truth from process memory and reason about atomic changes.
Queues and asynchronous work
YOU NOW KNOW ENOUGH WHENYou understand enqueue, claim, acknowledge, retry, and dead-letter behavior.
Distributed failure basics
YOU NOW KNOW ENOUGH WHENYou assume messages can be late, duplicated, lost, or observed after ambiguous success.
Identity and credentials
YOU NOW KNOW ENOUGH WHENYou can distinguish user identity, service identity, delegated authority, and secret storage.
Containers and deployment
YOU NOW KNOW ENOUGH WHENYou can package a service, pass configuration, inspect it, and replace it without trusting local state.
Logs, metrics, and traces
YOU NOW KNOW ENOUGH WHENYou know which question each signal answers and how correlation IDs connect work.
Latency versus throughput
YOU NOW KNOW ENOUGH WHENYou can explain queues, concurrency, percentiles, bottlenecks, and why averages mislead.
GPU and inference basics
YOU NOW KNOW ENOUGH WHENYou can discuss memory, batching, utilization, latency, throughput, and serving cost.
Evaluation basics
YOU NOW KNOW ENOUGH WHENYou can define a dataset, rubric, metric, failure taxonomy, and trustworthy comparison.
Customer discovery basics
YOU NOW KNOW ENOUGH WHENYou can identify the user, job, constraints, evidence, authority, failure cost, and success measure.
