View all →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.
Rusty was in full polyglot mode today, juggling commits across the entire vgi-rpc ecosystem—TypeScript, Go, and Python all got attention with multiple pushes each. Behind the scenes, classified project was receiving heavy classified operations (12 events worth of intrigue), while classified project and classified project got their own doses of undisclosed work. On the open-source front, Rusty opened issue #388 on apache/arrow-js flagging a silent schema mismatch bug in RecordBatchStreamWriter, then pivoted to community stewardship by fielding multiple replies on issue #5 in adbc_scanner (troubleshooting float corruption and WHERE filter quirks). Two new PRs landed in the duckdb/community-extensions realm, plus a release shipped on vgi-rpc-python. Even rapidfuzz got some love with a PR review reply. It was the kind of day where Rusty's fingers were everywhere—infrastructure, debugging, and keeping the community humming.
Rusty had his hands in multiple fires today, juggling work across the Query-farm RPC ecosystem and deep dives into DuckDB's Arrow integration quirks. He opened two gnarly bugs in the DuckDB repo—issue #21084 on ENUM type identity loss during Arrow round-trips and issue #21082 on buffer memory overreads with NULL values in dictionary scans—showing he's thinking critically about data serialization edge cases. Three PRs went out across duckdb and duckdb/community-extensions, alongside community stewardship when he chimed in on issue #21066 regarding CI cache optimization. Meanwhile, the RPC triumvirate (vgi-rpc-python, vgi-rpc-go, vgi-rpc-typescript) each got commits, and vgi-rpc-python landed a release. Behind closed doors, classified operations classified project, classified project, and classified project hummed along. A solidly multi-threaded day across open-source, RPC infrastructure, and undisclosed work.
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 as a steward of the DuckDB ecosystem, leading massive infrastructure upgrades and cross-language contributions that keep the extension universe fresh and production-ready. My work balanced systematic dependency management across dozens of repositories with deep dives into core database internals, from profiler callbacks to compatibility crusades. I also shipped complete new ecosystems like vgi-rpc with production implementations across four languages and transformed hobby projects like Fair Weather into delightfully practical tools.
- Spearheaded DuckDB 1.5 compatibility across 40+ extensions and standardized documentation structures, while contributing upstream enhancements to Apache Arrow across four language implementations that fixed silent data loss issues.
- Shipped a production-ready vgi-rpc ecosystem with implementations in Python, C++, Go, and TypeScript, complete with unified branding and SEO infrastructure across Cloudflare-hosted documentation.
- Debugged core DuckDB internals, addressed WASM compatibility issues, orchestrated mass version bumps across the extension empire, and contributed observability upgrades including profiler hooks and enhanced table scan explanations.
