What I use

A living list of the editor, languages, hardware, and services I reach for. Take it as recommendations, not endorsements — the day I stop breaking things with these is the day I'd want a refund.

[ EDITOR + TERMINAL ]

Neovim — primary editor
Cursor — secondary; the AI-assisted editor when I want a copilot in-line
Ghostty — GPU terminal; ligature-friendly, no JS overhead, fast startup
Zellij — session multiplexer; replaced tmux about a year ago

[ LANGUAGES ]

Rust — primary day-to-day language: chains, sidecars, security research
TypeScript — frontend + node SDKs; this blog is TS
Python — ML, scripting, glue. uv handles all installs.
Solidity — carry-over from ConsenSys days; still ship audits

[ STACK ]

Astro — this blog runs on Astro 4.16 + hybrid output
Bun — runtime + package manager; faster than node for this workload
NixOS — reproducible dev envs on the Linux side; see the NixOS + Bun.js post
Cloudflare Pages + Workers — edge hosting for the blog and side projects
Tailwind CSS — utility-first; paired with the Zera design system here
uv — single-binary Python package manager; replaced pip + venv

[ HARDWARE ]

MacBook Air M2 — daily driver; 8-core M2, 16GB unified, runs Groth16 in 1.5s
Milk-V Duo (RISC-V) — embedded AI / RISC-V experimentation
Framework Laptop — Linux/NixOS rig for chain-side benchmarking
Bitaxe (mining) — ASIC miner I run against Vanta regtest
Keychron Q1 — tactile switches

[ SERVICES ]

Cloudflare — DNS, CDN, Pages, Workers, R2, Browser Rendering, Workers AI
GitHub — code, issues, Actions
Stripe — donate button on the blog
cal.com — booking link for consulting calls
1Password — personal + team vaults; SSH key signing
Raycast — macOS launcher / clipboard / window-snap; replaced Spotlight
Arc — browser; spaces map cleanly to project contexts

[ FOUNDER STACK ]

Notion — long-form planning + customer notes
cal.com — booking link for customer + investor calls
Stripe — billing for any paid product surface
Cloudflare — primary cloud for Zera-side services
Latitude.sh — bare-metal seed nodes for Vanta L1 — primary chain infra
Fly.io — edge / failover for vanta-seed fleet

[ THINGS I'M CURRENTLY BOYCOTTING ]

Closed-source AI training on stolen code — if you trained on GPL without complying with GPL, you owe the world a tarball
npm packages with one maintainer and 40M weekly downloads — see: every Rusty Pipes post on this blog
