Python Lazy Imports (PEP 810): The Startup Speedup, Benchmarked
Python lazy imports (PEP 810) land in Python 3.15. I benchmarked boto3, requests and pydantic startup: the real speedup, and how to get most of it today.
Go's JSON v2 (encoding/json/v2): Faster, Stricter, and What Breaks
Go's encoding/json/v2 is a reported 2–10x faster at unmarshaling but flips v1 defaults: duplicate keys, nil slices, case matching. How to enable it and migrate.
Python 3.15: Lazy Imports, frozendict, and Faster Startup
Python 3.15 lands lazy imports, a frozendict builtin, unpacking in comprehensions, and the Tachyon sampling profiler. Here's what changed and what to test.
Rust vs Go in 2026: Which One Should You Learn?
Rust vs Go in 2026: learn Go for 80% of backends, add Rust for the 20% where 5x tail latency and 2–4x less memory pay off. Real benchmarks and salary data.
