Edgevane

Cumulative Layout Shift remains one of the most frustrating user experience problems on the web. Aisha breaks down the root causes — from font loading to dynamic ad injection to lazy-loaded images — and presents a systematic approach to achieving zero CLS scores using modern CSS techniques and resource hints.

Teaching Machines to Write Code: Building Son of Anton

Bertram Gilfoyle

Systems Architect @Pied Piper

Gilfoyle is the systems architect at Pied Piper, where he designed and maintains the company's server infrastructure. A self-described Anton LaVeyan Satanist and an uncompromising engineer, he built the AI system known as Son of Anton — a code-generation engine trained on Pied Piper's proprietary middle-out compression algorithm. He has strong opinions about proprietary software, server rack airflow, and why your deployment pipeline is wrong.

Pied Piper

Code generation is only as good as the architecture underneath it. Gilfoyle walks through the design of Son of Anton — Pied Piper's AI-assisted code generation system — from training data curation and model architecture to the custom server infrastructure that runs it. He covers the hard tradeoffs between latency and accuracy, why most AI coding tools get context windows wrong, and the systems engineering required to make machine-generated code actually trustworthy in production.
