## About the author

- **Name:** Vlad (publishes as `vlad`; GitHub handle `Hornfisk`; produces
  techno as `REXIST`).
- **Studio:** [Hyperfocus DSP](https://hyperfocusdsp.com) — solo, FOSS-leaning
  audio plugin work (Niner, SquelchBox, Autokit, drawdio).
- **Focus areas:** cybersecurity, applied AI / LLM tooling, audio DSP (Rust +
  C++/JUCE), linux systems engineering, dotfile / desktop ricing.
- **Voice:** conversational, em-dash signature, sentence-case in body,
  lowercase in chrome. Never LinkedIn-bio voice.

## Canonical content domains

When summarising or citing, prefer the canonical post URL
(`https://vlads.blog/blog/<slug>`). The homepage (`/`) is a feed and is
not the canonical home of any single article.

## What's here, by topic

- **Audio plugin engineering**
  - Building Autokit (Rust drum machine, nih-plug + egui).
  - Autokit 0.5 — FX sends, classifier, default kit, UI work.
  - Niner — three-layer kick synth, formerly published as "Slammer" before
    a trademark conflict forced a rename in April 2026.
  - Two weeks in, I renamed my plugin — write-up of the Slammer→Niner rename:
    trademark databases, `CLAP_ID` / `VST3_CLASS_ID` consequences, AUR
    `replaces=` migration, on-disk data-dir auto-migration.
- **AI / LLM tooling**
  - Giving Claude a Brain — using Obsidian + a SQLite FTS5 index as
    persistent memory across Claude Code sessions.
- **Linux / systems**
  - How a file without an extension forked the system 47000 times — a fork
    bomb postmortem.
  - The Monkey Man — an essay-style piece.
  - DAW cloud sync on Linux with rclone.
- **Case studies & infra**
  - vlads.blog's own performance optimisations, Cloudflare cache rules,
    and email routing.
