-This blog has migrated from Quartz to Zola. The previous version was feature-rich with backlinks, graph views, and Obsidian integration. This new version prioritizes simplicity.
-
-## Why the Change?
-
-Quartz is excellent for digital gardens and interconnected notes. However, for a straightforward blog, it carries unnecessary complexity. Zola offers:
-
-- **Fast builds**: Written in Rust, compilation is nearly instant
-- **Simple structure**: Plain markdown files with TOML frontmatter
-- **No JavaScript dependency**: Static HTML output
-- **Nix-friendly**: Single binary, easy to include in flake
-
-## What to Expect
-
-The content focus remains the same:
-
-- Machine learning techniques
-- AI systems and infrastructure
-- Conference paper summaries
-- Occasional homelab notes
-
-The design is intentionally minimal. No fancy features, just words on a page.
