Minification, uglification, and bundling get lumped together as "build steps," but each does something distinct. Here is exactly what each one changes in your code, with a before/after size example.

Auto-increment IDs leak your record count. Random UUIDs wreck index locality at scale. Here is a framework for choosing a primary key strategy based on how distributed your system actually is.

Retrying a failed GET is harmless. Retrying a failed POST can double-charge a customer. Idempotency keys are the mechanism that makes retrying a payment request safe.

The same API endpoint can return JSON, XML, or HTML depending on one request header. Here is how Accept and Content-Type headers negotiate response format, and what a 406 actually means.

Base64 is not encryption. A hash cannot be reversed to recover a password. Mixing up hashing, encoding, and encryption is one of the most common — and most dangerous — mistakes in application security.

A 429 Too Many Requests response is not a bug — it is the API telling you exactly how to behave. Here is how rate limiting algorithms work and how to build a client that respects them.

Same context window, same maximum output, 2.5x the price. A specification-by-specification and benchmark-by-benchmark comparison of GPT-6 Astra and GPT-5.6 Sol, and a straight answer on when the upgrade pays for itself.
