Ink is great, glad it’s gotten such a widespread adoption thanks to all those agentic tools
Are the new macbooks any good? Or would one just get an ipad pro and a remote vm to run Claude Code?

more movement to agentic behavior & computer use

cheaper than sonnet but on par (slightly better than) Sonnet 4.0

My friends at DuckDB Labs are hiring a DevOps Engineer (on-site in Amsterdam).

I know from experience that working on open source is fantastic, and this is a great opportunity.

DuckDB Labs provides services around the DuckDB in-process OLAP data management system directly from its main developers.

Yes, using Pub/Sub, Storage and BiqQuery right now - Cloud Run, potentially some GKE and Load Balancer with SSL cert handling is next. At least the plan looks very promising so far.
Have a Google cloud project which I’m working on recently, and I must say it’s a quite nice experience overall so far
An info message / warning by the OS would be nice
Turns out I was running my external hard-drive on the wrong port on my Mac Studio 🤪 And who fixed it? Claude Code.
Isn’t there something like max turns? Also, make it use (generic) sub agents
That’s actually not as bad as I expected it to be. Running verification scripts is a bit involved, but other than that can be a quite simple Test setup
Buckle up, I'm gonna use "terraform test" 😅

Built cryptographically-verified endorsements for at://work. The core innovation isn’t just cryptography, it’s the consent model. Both parties must explicitly agree to create a verified attestation. This changes how trust networks form. @atwork.place #ATProtocol
Building Unforgeable Professional Endorsements with ATProtocol - Nick's Blog
Traditional professional endorsements on platforms like LinkedIn lack cryptographic proof—anyone could forge them, and the platform controls the truth. This article introduces a two-record architectur...

The only thing worse than having Discord as the support community for your Open Source project is to use a free Slack space (where all messages disappear after 90 days). ;'(

I'm beginning to suspect that a key skill in working effectively with coding agents is developing an intuition for when you don't need to closely review every line of code they produce. This feels deeply uncomfortable!

what kind of queries / access patterns?
just stuff it into parquet files and dump it into a bucket 😅

We've released Gemini CLI extensions for querying PostgreSQL and MySQL with natural language.

If you're interested, take them for a spin! Oh and we'd appreciate any feedback you'd be willing to share 👇

mostly manual context building (with help of Claude Code or claude.ai) and then keeping track of changes / decisions in a file plus maintaining some sort of quick reference index file about the project (which component does what and where). Those frameworks felt a bit too strict for my cases

Yup. Claude coded a complete DuckDB Extension for me during my lunchbreak with the help of three MCP servers and a handful prompts… Crazy.
At this point, ignoring agentic coding tools is like refusing to use Git because you prefer manually tracking file versions in folders named 'final_v2_ACTUAL_final'
Yes! Also, research tasks in chatgpt or Claude.ai to generate use case specific docs
Prototyping with Claude Sonnet 4.5 is incredible 🧑‍🎨
