There needs to be a name for the prompt and context that "runs" an Agent/LLM -- Promptware, Thoughtware, Vibeware?

We now have many different "applications" running on the same models; different Vibeware running on Claude or Llama = different behavior = a different application.

Billion dollar idea: stand up a marketplace on top of Replicated or something which lets people set up a "virtual cloud" that runs other people's jobs in their own environment as a SaaS offering to leverage non-transferable cloud credits.

"Aggregated cloud as a service as a service"

Code review is more important now than ever. I keep seeing posts espousing a view to review AI generated code less, not more. Best of luck to those who wander down that dark path.

It's good to see thoughtful practice shared too --

If data puddles are tiny data lakes, do we need puddle houses?

How do people wrangle all their puddles of data now? Permissions management alone on hundreds of independently owned puddles sounds like home directories all over again.

Feature creep is the norm. If a project is a watercolor portrait, things become muddy shades of brown. Each beautiful addition, vibrant on its own, detracting from the work as a whole.

We must keep composition in mind. Readability is about more than a local change, how does it fit into the whole?

It's a testament to the lifetime elision ergonomics that, even after six years of enjoying regularly writing Rust, I occasionally have to re-up on my borrow checker knowledge.

I'd recommend this oldie-but-goodie for anyone but the most grizzled rustacean: github.com/pretzelhamme...

Software engineering is building with sand. Nothing is permanent. Code is change.

Like buddhist mandalas, there's an ephemerality to the art that must be acknowledged to be accepted.

As AI codegen gets better, code review is becoming an even _more_ important "basic" skill for engineers still mucking in code-land.

If you can't immediately find what's wrong in generated code, you're going to struggle to keep up.

Ever wanted to make a database out of something or query a DB with your own custom language? In SF March 19th?

I'm hosting a hackathon just for you.

Come get weird with DataFusion!

Ever wanted to turn something into a database? What about write a crazy query language? Send SQL to your toaster? This night's for you! DataFusion is like…

The Kesling Criteria (informally) --

A system is a database if:
1) You can ask questions of it
2) It returns data

For Papers We Love last week,
@alexkesling.bsky.social gave a talk on DataFusion and live demoed an increasingly awesome set of Rust databases built with it. If you’re free tomorrow, you should head to Rust NYC where he’ll go deeper on the internals and take it further.

Come learn how to "build" a database with me!

I'm presenting on February 5th at Datadog HQ on the paper "Apache Arrow DataFusion: a Fast, Embeddable, Modular Analytic Query Engine" (andrew.nerdnetworks.org/other/SIGMOD...).
