VGI Injector: A Tiny HTTPS Download-and-Execute Binary in Zig

I needed a self-contained binary that downloads a program over HTTPS and exec's it — small enough to run in a FROM scratch container with nothing else. Go and Rust couldn't get small enough. Zig could.

TIME Data Type Compatibility Across Databases

A survey of the TIME data type across 14 databases, comparing supported ranges, maximum values, and whether the special value 24:00:00 is accepted.

Telemetry for DuckDB Extensions Without the Pain

I open-sourced the telemetry client I use across Query.Farm's DuckDB extensions. It's two files, one function call, and it only collects platform and version info.

Releasing vgi-rpc: An RPC Framework Built on Apache Arrow

I built an RPC framework for Python that uses Apache Arrow IPC as the wire format and Python Protocol classes as the interface definition. No .proto files, no codegen — just type annotations.

Acronym-Aware Case Conversions in the DuckDB Inflector Extension

The Inflector extension for DuckDB now supports configurable acronyms, so case conversions preserve terms like HTML, API, and URL as fully uppercase — configured through a native DuckDB setting.

What I've Been Working On

Full activity log →

I've been deep in infrastructure and ecosystem work these past few months, balancing core database improvements with cross-language open-source contributions. February was all about DuckDB compatibility sprawl—future-proofing two dozen extensions while shipping a complete vgi-rpc ecosystem across Python, C++, Go, and TypeScript. I've also been leveling up Apache Arrow with custom metadata support and hunting down silent data drops, plus teaching weather apps to care about paw safety.

  • Led DuckDB 1.5 compatibility efforts across the Query-farm extension portfolio, opening 40+ PRs to standardize documentation and future-proof extensions like airport, shellfs, and inflector.
  • Contributed upstream Arrow enhancements across JavaScript, Swift, Rust, and Go implementations, adding custom metadata support for RecordBatch IPC messages that fixed production data loss scenarios.
  • Shipped a complete vgi-rpc ecosystem with production-ready implementations, unified branding, Cloudflare-hosted documentation, and Apache 2.0 licensing across all language variants.
