View all →Rusty wrapped up the hashfuncs extension with some housekeeping, merging PR #4 and updating the docs to showcase the new xxh3_128_hex() function in all its hex-encoded glory. Behind the scenes, classified operations hummed along across classified project, classified project, classified project, and classified project—a mysterious quartet of commits that shall remain forever shrouded in intrigue. Meanwhile, Rusty flexed his open-source stewardship muscles by providing feedback on DuckDB's profiler improvements (PR #21502) and helping the community-extensions crew get http_client shipshape for v1.15.0 (PR #1554), proving once again that great code is a team sport.
Rusty was a whirlwind across the Query-farm ecosystem today, orchestrating version bumps and feature refinements like a conductor fine-tuning an orchestra. He tackled OAuth enhancements in vgi-rpc-typescript (adding device code flow support and signing algorithm flexibility), knocked out a pesky Linux ARM64 build issue in inflector, and introduced a shiny new strip_accents option for diacritics removal—because sometimes you want your text squeaky clean. Meanwhile, behind closed doors, classified project, classified project, classified project, classified project, classified project, and classified project received classified attention across 17 commits of mysterious importance. He also played the gracious open-source steward, fielding community questions on httpserver (issue #50), httpclient (issue #31), lindel (issue #7), and inflector (issue #4), while shepherding three PRs (PR #1557, PR #1556, PR #1555) through the DuckDB community-extensions pipeline to keep those extension versions fresh.
Rusty spent the day juggling two distinct operations: 26 commits of focused work on vgi-rpc-website, where he tackled the unglamorous but crucial task of removing automated capability matrix overwrites and fixing the underlying capabilities data (the kind of infrastructure grooming that makes systems actually reliable), and 25 commits of classified tinkering behind closed doors on classified project. It was a day of meticulous cleanup and mysterious behind-the-scenes operations.
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 spent the last three months deepening my work across the DuckDB ecosystem and open-source infrastructure, with a focus on scaling extension compatibility, shipping production-grade systems, and contributing upstream to foundational projects like Apache Arrow. February highlighted ecosystem stewardship—future-proofing two dozen extensions for DuckDB 1.5 while launching a complete vgi-rpc ecosystem across four languages with unified branding and documentation. Between classified operations and public work, I've balanced high-impact infrastructure upgrades with targeted contributions to performance and data safety.
• Led DuckDB 1.5 compatibility efforts across the Query-farm extension portfolio, opening 40+ PRs to standardize and future-proof extensions like airport, shellfs, webmacro, and inflector while harmonizing documentation structures across 29 repositories.
• Shipped a production-ready vgi-rpc ecosystem with implementations in Python, C++, Go, and TypeScript, complete with unified branding, Cloudflare-hosted documentation, and Apache 2.0 licensing across the board.
• Contributed upstream enhancements to Apache Arrow across four language implementations, adding custom metadata support for RecordBatch IPC messages and public APIs for dictionary serialization to prevent silent data drops in production systems.
