LOGGING SUCKS

Traditional logging is inadequate for modern, distributed systems, usually providing little useful context for debugging issues. A shift to "wide events" or canonical log lines, which are single, comprehensive log entries emitted per request per service, may solve this problem. These events are rich in high-cardinality and high-dimensionality data, allowing for powerful queries and analytics instead of string searches.

SCALING LLMS TO LARGER CODEBASES

Scaling LLMs within large codebases requires investments in both guidance and oversight. Guidance focuses on providing LLMs with high-quality context, such as prompt libraries and well-structured, modular codebases, to allow for efficient "one-shot" code generation without needing a lot of rework. Oversight refers to human engineers who validate LLM choices, making sure of architectural integrity and aligned solutions.

EVERYONE IS A STAFF ENGINEER NOW

AI coding agents have become so good that they have fundamentally transformed software engineering, making code implementation inexpensive. This means engineers are increasingly expected to focus on higher-level skills like architectural judgment, system-level thinking, and managing complex contexts across multiple domains. Devs will need to start adapting their workflows, including planning and steering AI agents and developing habits to maintain focus amidst asynchronous work.

I'M A FORMER CTO. HERE IS THE 15 SEC CODING TEST I USED TO INSTANTLY FILTER OUT 50% OF UNQUALIFIED APPLICANTS

A 15-second coding test with a hidden character trick filters out 50% of unqualified remote job applicants, as good candidates would solve the code mentally, while others using interpreters or AI would get an incorrect answer.

YOUR SUPABASE IS PUBLIC

This dev frequently finds Supabase projects with exposed credentials, which, due to a lack of proper Row Level Security (RLS), grant full access to sensitive user data within the database. This vulnerability is surprisingly common. It allows simple `curl` requests to retrieve all user information from unprotected tables. While users are responsible for RLS, Supabase's design could be improved with clearer warnings or default secure configurations to prevent the anon key from becoming a master key.
