Slicing continuous art into a paged carousel breaks in specific ways. Here are the ones I hit.Thu, 09 Jul 2026 00:00:00 GMThttps://markostankovic.org/devlog/golden-fingerprints-generative-art/https://markostankovic.org/devlog/golden-fingerprints-generative-art/A refactor can shift one gradient band by a pixel and no test notices, until it ships. I regression-test my generative engines by committing SHA-256 hashes of the raw pixel and sample arrays. Here is the harness, and the rules that keep it from lying.Tue, 07 Jul 2026 00:00:00 GMThttps://markostankovic.org/devlog/skill-vibe-test-decay-probe/https://markostankovic.org/devlog/skill-vibe-test-decay-probe/Claude Code skills steer an agent well on turn one. I built skill-vibe-test to check whether the steering survives a long session, pointed it at one of my own skills, and had to throw most of the result away. Here is the part that held up, and how I know which part that is.Tue, 07 Jul 2026 00:00:00 GMThttps://markostankovic.org/devlog/zero-dollar-media-stack/https://markostankovic.org/devlog/zero-dollar-media-stack/My apps needed launch media: music beds, UI sounds, ambient video. Instead of licensing stock, I built numpy engines that synthesize all of it. Six music moods, 33 sound effects, fifteen scenes, nine overlay loops, every render deterministic and copyright-clean.Tue, 07 Jul 2026 00:00:00 GMT
