Have you been using an MTP setup? I've been having pretty good luck with the Qwen models with the built in MTP heads via https://mtplx.com at around Q4. My main driver rig is an M5 Max MBP work got for me a few weeks ago. Hitting 1000-1200 TPS prefill on Qwen 3.8-Flash-Next there.

having a 64GB mac mini m4 pro the last few years with some increasingly capable usefulness has kept me interested in this stuff in a way that using a paid platform wouldn't have. Similar to running K8s in a homelab, something about interacting with the hardware makes it more engaging/interesting, for me at least.

In general, I'm a big believer in doing more with fewer resources, within reason, and think having local setups really helps me be mindful with what's happening under the hood with these systems and managing context efficiently to get high quality results.

Same! Recently ported some code from httpx -> niquests and the experience has been good, although admittedly the governance of the project seems a little unclear.

I (ok, Qwen 3.7 27B) wrote some benchmarking code to compare throughput, and niquests seems to be substantially more performant for traffic that doesn't need to traverse the public web, e.g. intra cluster service to service communication:

Running httpx... Running httpx2... Running niquests...

> the only big gotcha I encountered was finding, somewhat counter-intuitively, that it's often best minimize partitioning.

For parquet, I think with partitioning, it's really important to be mindful of the ordering of the data within the parquet file and also the query patterns of the main use cases. A little hard to generalize well to every pattern I guess.

For a schema-first (vs. code first) approach (which I think would be a sweet spot for agent driven dashboarding), I'd suggest looking at https://vega.github.io/vega-lite/ or https://vega.github.io/vega/. A little higher level than full D3 but gives you a little higher level approach.

I don't think DuckDB itself can coordinate work across multiple nodes. But you could put it behind an HTTP layer and scale horizontally based on resource utilization?

I've got a couple of different use cases:

- ETL pipelines running on K8s nodes. Using their streaming processing engine means I can run smaller pods/nodes if needed, for datasets that may have required large dataframe-like transformations that may have buffered a big dataset into memory previously.

- A CLI distributed to an internal team to do a postprocessing step on a large modeling dataset - to get it into a consumable format and upload it to a bucket as a .db file.

- A SvelteKit app that used the node duckdb bindings to attach to the .db on the bucket and explore the results through a suite of BI tools. These tables have millions of rows, and would be pretty heavy to store in PG. The DuckDB version works really, really well.

DuckDB is one of the things I've been most excited about in a long time. Introduced it to projects at 3 companies since 2023, greatly lowering resource requirements and running it in a variety of environments. Just having the ability to do out of core bigger than memory data processing on lower end consumer grade hardware is remarkable.

Thanks to the team for everything!

https://github.com/antirez/ds4 coming out at the same time I started a new job and they gave me an m5 max a few months ago was the lightbulb moment for me.

Buf.build, never again. Had a proto evangelist get us ingratiated into their system a few years ago and then they introduced a bunch of rent seeking behavior just to be able to to the code generation, and getting it ripped out was a huge PITA. https://github.com/betterproto/python-betterproto2 was a decent (async, type hinted) python implementation last I checked.
