The v0.2.0 release of my @duckdb.org quack protocol TypeScript client now also supports Apache Arrow as inputs/outputs: github.com/tobilg/quack...

Today I'm releasing the first experimental build of CereusDB, a WebAssembly build of Apache Sedona's single-node SedonaDB: github.com/tobilg/cereu...

On the weekend, I built an experimental VS Code extension that enables using Ghostty as terminal inside the IDE. It works already fairly well with AI tools like Claude Code or OpenAI Codex for those who do not like the internal terminal. marketplace.visualstudio.com/items?itemNa...

My @duckdb.org in-browser terminal now supports v1.5.0. You can upload local datasets, query remote data and even generate automatic visualizations: duckdb-terminal.com

I created a simple OCR CLI tool for macOS that can be used to pipeline plain and structured text contents to AI tools from images, without having to upload the images to the model providers. It can remove PII data with a simple flag as well. github.com/tobilg/simpl...

Just updated my Ducklings project to @duckdb.org v1.5.0. You can also deploy it to @cloudflare-dev.bsky.social Workers if you have a Pro plan, e.g. to query Parquet files in R2. github.com/tobilg/duckl...

Whoa, this thing is so fast...

Introducing polyglot - A Rust/Wasm SQL transpiler for more than 30 SQL dialects. It has 100% coverage for sqlglot‘s test fixtures. github.com/tobilg/polyg...

I just burned through the $50 Opus 4.6 fast mode credits with a single subagent in less than 14 minutes... As far as I understood the usage is currently 50% discounted as well. Not sure who's the target group of this tbh. 🙃

🎞️ The slide decks and talk recordings of last Friday's developer meeting are out! duckdb.org/events/2026/...

What if you could talk to your @duckdb.org? 😃 This was a fun experiment using local Whisper model and a local Text-to-SQL proxy to actually query your database with your voice! The extension will be released soon...

It ran 11.5 hours iterating from a single prompt until the disk was full with 40GB Rust build artifacts 😬 Impressive what the new Claude Code task system can do w/o any MCPs/skills/etc.

Ducklings was updated to the latest @duckdb.org v1.4.4 - Run DuckDB on @cloudflare.social Workers with R2 support github.com/tobilg/duckl...

Claude Code is happily fixing bugs & refactoring the application since more than 5.5 hours since the last prompt... Who needs Ralph, Gas Town and the likes?

AI Observer now supports session transcripts for imported and live sessions, as chat or timeline view. This all runs entirely on your machine, without sending data anywhere. Give it a try: ai-observer.dev

Just crossed 3B token/week on Claude Code 😂

Just ask Claude Code whether implementation steps can be parallelized...

Got Claude Code Max 20x three days ago and since then I average at 500M token/day 😬

My @duckdb.org Terminal now also supports using local AI tools via Text-to-SQL proxy:

Claude Code just one-shotted a migration of a fairly complex Electron app to Tauri in about 20min... Planning mode with a few lines prompt -> Success. Incredible.

If you're building or using local-first applications that need Text-to-SQL generation, and have a subscription of Claude Code, Codex, Gemini, OpenCode or Continue, this might come handy: github.com/tobilg/text-...

A minimal DuckDB Wasm build for browsers and serverless environments like @cloudflare.social Workers github.com/tobilg/duckl...

I have @duckdb.org running on @cloudflare.social Workers

I love it, Claude Code overloaded the second day in a row... Great to pay $$$ for this.

@duckdb.org Wasm on @cloudflare.social Workers was achieved internally 👍

AI Observer has a landing page now ai-observer.dev

AI Observer v0.2.0 was released with many improvements: - Import historical sessions from Claude Code, Gemini CLI, and Codex CLI local files - Export telemetry to Parquet - Embedded pricing for 65+ models with automatic cost calculation - Dashboard export/import support.

Over the holiday I built a single-binary observability app for Claude Code, Codex and Gemini. It supports gathering metrics, logs and traces via the OTLP exporter. Configure custom dashboards, view and search logs, view metric timeline data and trace waterfalls. Built upon @duckdb.org

Today I used Claude Code to debug an issue of the Gemini CLI 🤷🏼‍♂️ github.com/google-gemin...

All I want for Christmas is... an Apache Iceberg Workbench in the browser!?

New blog post: tobilg.com/posts/using-...

In seven weeks, we will host the first DuckDB Developer Meeting in Amsterdam. We have four exciting talks lined up on building extensions in DuckDB, encryption in DuckDB, DuckPL and GizmoEdge. For more details and the registration links, please head to duckdb.org/events/2026/...

My DuckDB Terminal now has a user guide, and was updated to the latest DuckDB v1.4.3 and ghostty-web v0.4.0 terminal.sql-workbench.com/guide/

New blog post: TypeScript scripts as @duckdb.org table functions tobilg.com/posts/typesc...

DuckDB Terminal has been updated, it now supports auto-magic charts, data downloads and many other features: terminal.sql-workbench.com

New @duckdb.org Web Terminal just dropped: terminal.sql-workbench.com

Migrated @sql-workbench.com on the weekend from AWS (CloudFront, S3, Route 53, etc.) to @cloudflare.social Pages... Went from >400 lines of CloudFormation IaC to 5 lines of wrangler.jsonc

In DuckDB v1.4.2, we shipped a number of features and improvements to the DuckDB-Iceberg extension: insert, update, and delete statements are all supported now. Read Tom Ebergen's new article on these features at duckdb.org/2025/11/28/i...
