Dex Horthy explains why context engineering is key to building more effective AI-assisted software without sacrificing code quality.

Introduction The setup Laying the foundation The foundation: schemas and user roles for modularity Domains Accounts, managed and external Transfers, constrained by a state machine and temporal periods Transfer state history Account auditing Transactions, the immutable events On maintaining business rules via meaningful constraints The transfer state machine Transactions must fall within the transfer period Pending transactions require a pending transfer No future transactions when closing a transfer On capacity planning Working set estimation On write throughput Enabling HOT Updates for Transfers Making sure there are no Unused indexes OLTP Listing The history of a transfer OLAP Balance ledger Incremental maintenance via triggers On serializable isolation On decoupling Benchmarking the startup scenario Seed data Write script: full transfer lifecycle Read script: activity stream and balance Running the benchmark Results Conclusion Appendix A: Full code suite. Introduction There is a deep cultural reflex in modern engineering: whenever a problem appears, reach for a packaged solution instead of thinking from first principles. The result is architectural cargo culting and lots of missed opportunities. Some intentionally absurd-but-familiar examples:

Taste used to be a byproduct of the reps. Agents took the reps. So if you're junior you now have to go get the taste and judgment on purpose. A builder's loo...

Today, at WeAreDevelopers World Congress, we are announcing Google Cloud Run sandboxes in public preview. Cloud Run sandboxes are a native, secure, and ultra-fast runtime environment built specifically for executing untrusted code and agent workloads, starting in milliseconds.

As AI agents commoditize the execution of code, the leverage moves to the two things a machine can’t do for you: deciding what belongs on…

OpenAI は CoT-Control を公開し、リーズニングモデルが思考の連鎖を制御するのに苦戦していることを示しました。これにより、モニタリング性が AI 安全性のセーフガードとして有効であることが裏付けられます。
