View all →Rusty was a busy bee today, shipping multiple releases on vgi-rpc-python with 5 commits across that repo alone, keeping the momentum high with push events and release cycles. Behind the scenes, classified operations at classified project, classified project, classified project, and classified project required attention—because apparently some projects demand discretion. On the open-source front, Rusty was in full stewardship mode, providing expert feedback on issue #5 in adbc_scanner regarding float corruption and ADBC driver quirks, and diving deep into a thorny buffer overread bug in PR #21083 on the main duckdb repository—contributing multiple rounds of review and guidance to help crush that Arrow dictionary conversion crash. A solid day of shipping, reviewing, and keeping the DuckDB ecosystem healthy.
Rusty shipped a release for vgi-rpc-python, marking another milestone for the RPC toolkit. While the day saw zero commits and no PRs merged, the release event itself represents the culmination of prior work—sometimes the best days are about crossing the finish line rather than grinding new code.
Rusty spent the day juggling a multi-language RPC symphony, spreading commits across vgi-rpc-python, vgi-rpc-typescript, and vgi-rpc-go like a seasoned conductor keeping all three orchestras in sync. Behind closed doors, classified project, classified project, and classified project received classified attention as well. On the open-source stewardship front, he fielded community support on rapidfuzz (issue #4) and troubleshot a thorny data corruption bug over on adbc_scanner (issue #5). He also opened a PR on the DuckDB community extensions, cracked open a fresh repo with arrow-js, and contributed to the Apache Arrow JavaScript ecosystem—all while maintaining the kind of distributed momentum that makes polyglot development look effortless.
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 spent the last few months deep in ecosystem stewardship, shipping major infrastructure upgrades and open-source contributions across the DuckDB universe while maintaining a healthy portfolio of classified work. February was particularly productive—I led a massive DuckDB 1.5 compatibility push across dozens of extensions, contributed upstream enhancements to Apache Arrow across four language implementations, and shipped a complete production-ready vgi-rpc ecosystem with unified branding and documentation. The theme running through January to February has been about scaling impact: whether it's teaching extensions at workshops, hardening cryptographic functions, or discovering security issues before they ship, it's all been about building better infrastructure for the data community.
• Led DuckDB 1.5 compatibility across 40+ extensions including airport, shellfs, webmacro, and inflector while standardizing documentation across 29 repositories
• Contributed upstream Apache Arrow enhancements across JavaScript, Swift, Rust, and Go with custom metadata support and dictionary message serialization fixes
• Shipped complete vgi-rpc ecosystem with production implementations in Python, C++, Go, and TypeScript, including unified branding and SEO infrastructure
