HARNESS, SCAFFOLD, AND THE AI AGENT TERMS WORTH GETTING RIGHT

An AI agent is defined as the combination of a core model with a behavior-defining scaffold and an execution-focused harness. These systems use context engineering and sub-agents to manage memory and break down complex objectives into specialized, autonomous tasks. In training scenarios, reinforcement learning structures like rollouts and rewards provide the essential data and scoring mechanisms needed to refine model weights through environmental interaction.

LEAVE ME BEHIND

Traditional software development was a soulful craft rooted in human connection, collaboration, and the expertise gained from trial-and-error. Rejecting generative AI's automation is necessary to preserve this vital human element and maintain programming as an art form.

JEN CAN NEVER LEAVE

Many organizations depend on a single expert's unique judgment for interpreting complex payroll data, as traditional documentation fails to capture this fluid wisdom. AI systems can solve this by processing standard files and flagging ambiguities for human review, turning experts into force multipliers whose insights are encoded into automated, autonomous rules.

NOBODY CRACKS OPEN A PROGRAMMING BOOK ANYMORE

Physical programming book sales are declining because generative AI tools and automated coding assistants have replaced printed manuals by offering instant solutions. Although traditional learning from books fostered a deep understanding, this shift toward AI represents a fundamental change in software engineering, moving developers to higher abstraction levels.

C CONSTRUCTS THAT STILL DON'T WORK IN C++ — AND A FEW THAT CHANGED

C and C++ maintain distinct object models, requiring developers to focus on specific standards (C23 or C++20) for code validity, and while some features align, memory management using C functions like malloc remains risky in C++. Effective cross-language development demands isolating C-specific features and translating them into robust C++ types to guarantee safety and clear ownership.
