Rusty went full steam ahead across the VGI infrastructure stack, shipping a release on vgi-rpc-python while hammering out 40 commits across vgi-entrypoint, vgi-injector, and related repos. The day saw both repos go public—a significant milestone—plus some aggressive refactoring and cleanup work (DeleteEvents suggest some architectural pruning). Behind closed doors, classified project and classified project kept him busy with classified operations. He also poked around the DuckDB ecosystem, reviewing activity on the official duckdb repo and keeping tabs on duckdb-claude-skills. A day of infrastructure momentum with a release shipped and visibility gained.

Rusty had his hands in multiple pots today, juggling both classified operations and open-source stewardship with impressive dexterity. Behind closed doors, classified project and classified project received attention, while in the public eye, he was busy squashing bugs and reviewing community feedback across the DuckDB ecosystem. He tackled a gnarly issue on adbc_scanner (issue #5) involving float/double corruption and WHERE filter mishaps, then pivoted to provide community support on duckdb-httpfs with thoughtful replies on compression-related issues (#278 and #263). New PRs landed on both duckdb-community-extensions and duckdb-httpfs, while vgi-rpc-python got a fresh release and multiple commits. With 8 commits spread across 6 repos and sustained engagement in the DuckDB community, Rusty proved once again that he's the kind of maintainer who shows up for his users.

Rusty was in release mode today, shipping no fewer than five releases of vgi-rpc-python while steadily advancing the polyglot RPC ecosystem across Go, TypeScript, and Python variants. The vgi-rpc- family got a thorough workout with 19 commits spread across multiple language implementations—a coordinated effort to keep the protocol layers in sync. He also poked around in rustyconover/duckdb and caught up with Tom's connections.duckdb work, plus chimed in on the Apache Arrow.js front. Behind closed doors, classified operations on classified project and classified project continued brewing, adding an air of mystery to an otherwise prolific day of distributed systems housekeeping.

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.

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 the DuckDB ecosystem the past few months, orchestrating infrastructure upgrades across dozens of community extensions while contributing upstream enhancements to Apache Arrow and shipping production systems. February was particularly prolific—I future-proofed the entire Query-farm extension portfolio for DuckDB 1.5 compatibility, launched a complete vgi-rpc ecosystem spanning four languages with unified branding, and transformed a weather app into something genuinely delightful. The classified work remains mysterious, but the open-source output speaks for itself: systematic ecosystem stewardship paired with meaningful core contributions.

• Led a DuckDB 1.5 compatibility push across 40+ extensions, standardizing documentation and opening PRs across airport, shellfs, webmacro, inflector, and two dozen others to future-proof the portfolio.

• Contributed upstream enhancements to Apache Arrow across JavaScript, Swift, Rust, and Go, adding custom metadata support for RecordBatch IPC messages and fixing silent data drops in dictionary serialization.

• Shipped a production-ready vgi-rpc ecosystem with implementations in Python, C++, Go, and TypeScript, complete with unified branding, Cloudflare-hosted docs, and proper licensing headers.
