My coding-agent sessions are more expensive now. The useful spend is the part that turns mistakes into better tests, graders, prompts, and checks.
Camping Indoors in San Francisco
My first week in San Francisco: paperwork, an unfurnished apartment, two cats, Bay Trail runs, and waiting for furniture.
Coding Agents for Inspectable Browser Tools
Building frontend-only tools for load flow and Mandelbrot zooming gave me concrete ways to inspect older technical models.
Dropout as Shared-Parameter Bagging
A concrete way to understand dropout in deep learning: sampled subnetworks with shared weights, standing in for a much more expensive ensemble.
Studying with the 11-Inch M3 iPad Air
Notes on the 11-inch M3 iPad Air for reading, handwriting, and remote access without turning it into a laptop replacement.
One Manifest for Responsive Images
I replaced scattered responsive-image conventions in a Next.js static site with one generated manifest for variants, dimensions, and runtime lookup.
Make Internal Tools Cheap to Try
AI-assisted prototypes make small workflow ideas cheap to test before they compete for dedicated engineering time.
Codex for Site Edits, Sora for Visual Sketches
How Codex made small website edits easier to make from a phone, while Sora still feels more useful for exploratory visuals than finished work.
Depth Changes Scaling, Not Just Capacity
Chapter 6 separates representational capacity, parameter efficiency, and learnability—and shows why depth changes scaling, not just expressiveness.
Math Foundations for Deep Learning
Part I of Goodfellow, Bengio, and Courville works best as shared vocabulary for later chapters, with proof details still worth supplementing.
Planning and Verification in AI-Assisted Coding
How my AI-assisted coding workflow shifted from quick snippets to clearer briefs, review checkpoints, and build/lint/test verification.
Static Markdown Inside This Next.js Site
How repo-backed Markdown becomes static HTML without a CMS, database, or runtime admin surface.
